Authors:
Alex Henni, Bonida Rooinasi
Abstract:
The problems of parallel organization of processes of simulation of dynamic problems of large dimension are described, which are described by systems of ordinary differential equations. The account of the sparseness of the matrixes of coefficients can significantly reduce the complexity of numerical implementation of dynamic models, since each step of integrating such problems, as usual, reduces to the execution of matrix or matrix-vector operations, the optimal implementation of which depends on the possibility of obtaining an effective solution with the use of parallel computers. Particular attention is paid to the methods of compact placement of matrix elements in memory, the execution of matrix operations, as well as the allocation of multiprocessor systems resources when working with sparse matrices.

An Improved Optical System in Dentistry – Transition to a More High Level of Treatment
Authors:
Joseph Jacou
Abstract:
Despite the obvious advantages of using a microscope in dentistry, it is currently used only by high-tech dental centers, located mainly in large cities. One can assume that the reason is a significant cost of equipment. However, studying this issue has shown that the real reason is different – working with a microscope requires a doctor of serious skills and experience with magnifying equipment, and also requires specialist qualifications, and therefore, professional retraining, since the movements of hands when using this equipment are significantly different from manipulations with the usual treatment of teeth. This article outlines the main advantages and briefly considers the possibilities of using optical magnifying systems in dentistry (for example, a dental microscope) and offers an improved optical system in dentistry.

Abstract:
In the paper, the analysis of the restoration of the thermal field configuration by discrete values is carried out using methods of bilinear interpolation and rescaling of Lanczos. An analysis of the mean square deviation and spectral characteristics shows that the minimum hardware does not allow the field to be adequately restored due to the impossibility of registering the high-frequency component. The advantages and disadvantages of alternative methods of representation of a thermal field on the basis of pyrometric sensors are considered.

Abstract:
Telecommunication systems are widely used in almost all branches of human activity. With long-term operations, telecommunications equipment can be damaged, which leads to undesirable information loss. The process of diagnosing the critical states of a telecommunication system is quite laborious and requires an analysis of many factors and parameters in order to accurately identify and eliminate the problem. To speed up this process, neural network technologies can be used. In this article, the main components of the neural network and its applications for the diagnosis of critical states of telecommunication systems are considered.

Artificial Bandwidth Extension for Speech Signals Using Phonetic Classification
Authors:
Abstract:
This article presents a new strategy for implementing artificial bandwidth extension (ABWE) systems for speech signals applied to telephony in packet networks. In the literature, several approaches are proposed; however, there is not yet an adequate procedure that can satisfactorily represent speech segments with concentrated energy at high frequencies. In order to improve the performance of these systems, a new strategy based on phonetic classification is discussed here. The results obtained are evaluated and the quality enhancement of the reconstructed speech signals confirms the effectiveness of the proposed strategy.

Abstract:
This paper proposes a performance evaluation methodology as well as compares some visual quality metrics for perception threshold characterization in images degraded by Gaussian additive noise. Both non-perceptual (SNR and PSNR) and perceptual metrics (MSSIM, IFC, FV and C4) are evaluated. The subjective evaluation experiment that serves as a basis for the presented results is performed with approximately 120 observers, considering a test set with 60 images, divided into five groups. The data analysis seeks to estimate a detection threshold value for each of the metrics evaluated as well as the quality obtained from the corresponding estimate.

Greedy Genetic Algorithm for Selection of Text Corpora Used in Speech Processing Applications
Authors:
Horvath Novikov, Elizabeta Radizinskaia
Abstract:
In recognition, synthesis and speech conversion systems, a text corpus is required to obtain the speech bank taken as a reference in the development of such systems. The selection of this corpus is often performed automatically through the solution of an optimization problem to maximize a function that represents phonetic / prosodic coverage. The state-of-the-art technique for solving such a problem is called additional greedy. When compared to other approaches presented in the literature, additional greedy exhibits low computational complexity; however, it performs poorer results in the optimization process. In order to improve this performance, this paper proposes a procedure for selecting the corpus based on two steps. First, additional greedy algorithms are applied in the selection of a smaller corpus from a larger initial corpus. In the second step, a greedy genetic technique selects a new set of sentences using the resulting corpus of the first step. In this way, a better compromise relationship between complexity and performance is established in the optimization process. To our knowledge, the greedy genetic selection technique has not been used before for this purpose.

Syntagmatic Classification Focusing the Synthesis of Speech
Authors:
Aghastasia Baklanova, Tatiana Ket
Abstract:
The prosody target of concatenated speech synthesis systems is obtained by using modeling algorithms trained in an offline procedure. These algorithms are developed with reference to linguistic characteristics (for example, syllabic separation, tonicity and division into phonological and classification of phrases) of the sentences contained in a recorded speech bank. In this work, a procedure is presented for automatic classification and division of sentences into phonological phrases. The classification is based on rules that result in a hit percentage of 92.86%. Moreover, it can help in the process of predicting pauses, leading to an adequate establishment of concatenated speech synthesis and, consequently, to a better naturalness of synthetic speech.

Refinement of Phonetic Segmentation in Applications of Speech Synthesis
Authors:
Olesa Yacenkova, Valekema Lapina
Abstract:
Speech is generated from the juxtaposition of automatically selected segments of parts restricted in a earlier recorded and partitioned bank in concatenated synthesis. The synthetic speech obtained through this technique presents naturalness influenced by the effectiveness of the segmentation tools. The act of such tools is regularly favored by a mixed method causing from an HMM model through a refinement method of segmentation. This refinement has been successfully accomplished through the use of techniques based on neural networks. In this work, it is proposed a set of networks whose performance is superior to the other topologies of neural networks presented in the literature. In this case, the training of the networks is done by a distribution of the training set based on the borders of phonemes with similarities between them.

A New Non-Maximally Decimated UEPS for Blind Source Separation
Authors:
Salah Al-Din Badran, Abdel-Hamid Soliman, Ismail, Shahin, Alistair Duffy
Abstract:
The problem of blind source separation (BSS) refers to recovering original audio signals, called source signals, from the mixed signals, called convolutive mixtures or observation signals, in a reverberant environment. The mixture is a function of a sequence of original speech signals mixed in a reverberant room or ambient. The objective is to separate mixed signals to obtain the original signals without degradation and without prior information of the features of the sources, such as the locations, the spectral nature or the mixing method. The strategy used to achieve this objective is to use multiband schemes. Multiband schemes work at a lower sampling rate, have less computational cost and a quicker convergence than the full-band approach. For more challenging scenarios, an unequal-passbands scheme with oversampled decimation is proposed for blind source separation application; the greater number of bands, the more efficient the separation. The results are compared to the currently best performing method and three standard methods and show a significant improvement in the computational saving and convergence speed.

Improvement of the Troubleshooting in a Computer Network Based on Matrix of Accuracy
Authors:
Krista Huang, Jessica Berzina
Abstract:
Nowadays, local area networks (LANs) are widely used and probably will be used later. But the larger and more complex the network, the more problems and malfunctions in it can arise. Therefore, it is necessary to increase the fault tolerance and reliability of local computer networks, especially in the structures of enterprises, where LAN is a key tool in the work. Network performance is provided by eliminating bottlenecks in the network nodes and collision domains, which reduce the speed of operation and can lead to the interruption of the signal from the network node. In these cases, it may take a long time to restore the LAN operation, which can lead to idle time and financial losses. Also important is the security of the network, which can be improved by installing network filters, and setting the appropriate security policy for each network node. This article deals with the method of correction of a single failure in a local computing network. The matrix of reach is constructed through the adjacency matrix.

Solution of the Problem of Factorization of the Correlation Matrix of the Multiplayer Dynamic System with Advanced Information Technologies
Authors:
Olenka Mishtik, Anastaciya Onishik
Abstract:
The factorization of a covariance function or its analog in the frequency domain – spectral factorization – is a much more difficult task than the synthesis of a covariance function or spectrum. When considering the factorization problem, two questions arise. The first is connected with the motivation of why it is necessary to study this task in general, and the second one – with the choice of the most effective procedure for factorization. The necessity of studying factorization algorithms follows from the fact that in many tasks there is no information on the process generation, and the known measured characteristics of the output process: covariance function or spectrum. Regardless of any consideration of the discovery or evaluation, it is desirable to find a model for describing the dynamics of process generation, since it can give a deeper understanding of the physics underlying the task. In the context of detection and evaluation, many of the synthesized receivers contain devices for evaluating process parameters. In many tasks, the implementation of the relevant evaluation algorithms requires knowledge of the generation model. This article is devoted to the development of the software application Trinity-factor for determining the noise signals by the factorization method of the correlation matrix of the multidimensional dynamic system.

Generation of Random Removals for Different Types of Source of Light
Authors:
Takumi Ishii, Yuma Saito , Daiki Sakamoto
Abstract:Abstract:
One of the main characteristics of a light instrument is the curve of light intensity. There are many methods for calculating the light intensity curve, and one of the most modern ones used in most automated calculation programs is the Monte Carlo method. The Monte Carlo statistical method is based on the direct mathematical modeling of the research object, which consists in simulating the propagation of rays from the light source, reflection from the reflecting surface and fixing on the calculated plane. The paper considers three main types of light sources: bullet, disk, and cylinder. Formulas for a random beam were derived for a ball source and a disk type. For a cylindrical source, a random beam formula already exists. Also, the influence of the form of the light source on the model of the random beam coming from the source was investigated. The results obtained in the future can be used to generate a random beam, to simulate reflection from the reflecting surface and to the light intensity of the light instrument.

New Method and Device for Measurement of Local Thicknesses of Films from the Frame of the Film Centrifugal Sprayer
Authors:
Naoya Endo, Kazuya Aoki, Yuuki Fujii
Abstract:Abstract:
A very wide range of applications: in the food, chemical, pharmaceutical and other industries for heat and mass transfer between liquid droplets and gas phase in spray drying, absorption, interphase, liquid cooling, gas conditioning and other similar processes. Such a wide range of use of centrifugal film nozzles indicates the high efficiency of this device. The high efficiency of film nozzle operation strongly depends on the parameters of the film flowing from the edges of the nebulizer, in particular the speed of film movement and the distribution of its thickness on the edge of the film-forming device. However, the study of the process of spreading the liquid film when it moves along the rotating wall of the film-forming agent, the process of decay of the film flowing from the edges of the film-forming agent, as well as the measurement of its thickness, is still not sufficiently studied. We have developed a method and device for measuring the local thicknesses of films flowing from the edges of the film-forming device of a film centrifugal atomizer. The proposed new method and device for measuring local film thicknesses of a centrifugal atomizer flowing from the film former is presented in the paper, which allows measuring the film thickness distribution from the film former.

Mathematical Model of a Multi-Frequency Picorecondous Vibrational System with External Capacitive Mems Control
Authors:
Sim Chong-sik Ma, Heo Man, Yang Keon Mangjeol
Abstract:Abstract:
The controllability of generated oscillations is one of the most important characteristics of piezo-resonance oscillation systems, which are increasingly used both in telecommunication systems, where they are traditionally used to form high-stability signals and their processing. In this case, there are two control tasks: the first is to ensure the frequency invariance of the generation relative to the effect of the destabilizing factors (minimization of controllability), which is characteristic of the generators of reference signals and quartz filters; the second is to provide the specified control characteristic (quartz FM modulators). A special significance of the controllability property is acquired when multi-frequency excitation of a quartz resonator, where, in the overwhelming majority of cases, it is necessary to simultaneously solve two problems: to provide invariance with respect to one frequency and to form the necessary control characteristic in relation to another. The future perspective is the application of controlled piezo-resonance oscillatory systems with external capacitive micro-electromechanical control (MEMS) for solving control problems in multi-frequency generators. An adequate mathematical model of a controlled piezoresonance oscillatory system with external capacitive micro-electromechanical control is developed. Recommendations are formulated to optimize the characteristics of the generator control.

Solving the Problem of Calculating the Cold-Saddle Instrument as a Thick-Style Cylinder for Dynamic Loading
Authors:
Lovisa Axelson, Anna Granholm, Alexander Forsman
Abstract:
A fundamentally new formulation of the Lame problem for the calculation of axisymmetric thick-walled shells is considered, taking into account the dynamic nature of the application of the load. The task in this formulation allows us to analyze the influence of dynamic processes on the strength characteristics of the tool, and also take them into account in the engineering methods of calculating and designing the tool. This approach reflects a more realistic picture of the stress-strain state arising in the cold-setting tool in the conditions of automated production of hardware products. The practical value of the study is that this equation is a fundamental equation describing the dynamic state of a thick-walled shell loaded with an axisymmetric load. Using this equation, one can find the spectrum of natural frequencies and proceed to the study of both free and forced oscillations of a cylindrical shell.

Abstract:
The analysis of features of drainage of liquidated mines with submersible pumps is carried out. The necessity of the work of the drainage plant in the state of stabilization of the level in the drainage basin is substantiated. The model of the drainage system with submersible pumps, which works in the mode of stabilization of the level in the drainage system, is proposed – the work “on the tide”. The performed analysis of the simulation results showed the impossibility of using P-regulators and regulators containing an integrative component. It is shown that the necessary control quality can be achieved by using the internal pump supply stabilization circuit and using the PD regulator in the main control circuit.

Abstract:
The article deals with the problem of waste disposal of existing landfills, which entered the stage of disintegration. To improve the efficiency and ecological safety of the utilization of the dispersed phase of waste by various methods, it is suggested to subject them to preliminary preparation. The aim of the research was to substantiate, based on the scientific and experimental results obtained, the choice of means for preparing a disperse phase of landfills for further processing. An analysis was made of the existing methods of waste disposal in accordance with the features of the dispersed phase of solid waste. As applied to them, several methods of preliminary preparation of raw materials are considered, an important stage of which is granulation. Theoretical and experimental studies of such pelletizing methods as pelletizing, fluidization and pressing of the products of TBT decay with the purpose of determining the process parameters significantly affecting the efficiency of the granule formation process and the quality of the resulting granules were carried out. Based on the results of the research, the main regime parameters of the waste granulation technology by various methods were substantiated and recommendations for choosing the method of preliminary preparation for their effective utilization were given.

Abstract:
Estimating the technical condition of manufacturing equipment and defining its residual resource is an important task for companies in the chemical industry. The optional decommissioning of the equipment which has recovered the resource makes it possible to prevent situations of damage, which can lead to the stoppage of the manufacturing processes, the destruction of the equipment and the material damage related to it, as well as such serious consequences as the appearance of fires, explosions, pollution of the environment and the death of the life and the health of the people. The method of the account of the residual resource of gas pipes, which are under rarefaction, is developed. Account is taken of the residual resource of the gas line on the output of the primary gas refrigerators at the base of the inspection materials of its technical condition.

Solution to the Hydrogen Effects in the Palladium-Hydrogen System
Authors:
Hang Mae, Yu Chae-hyeong Maeng, Yun Chun-sang Myeong
Abstract:
The palladium-hydrogen system is a classical metal-hydrogen system both from the point of view of the problems of condensed state physics and in a broader scope of theoretical and practical problems. Any heterogeneity in the distribution of hydrogen, any gradients in the concentration of hydrogen causes the appearance of the corresponding deformations and stresses in the solid. These stresses, by analogy with thermal stresses, are called hydrogen concentration stresses. By analogy with the phenomenon of thermoelasticity, the phenomenon of occurrence of hydrogen concentration stresses in the Me-H system is called the phenomenon of hydroelasticity. In this paper two more hydroelastic effects will be discussed. Namely, the effect of stationary coherent reversible micro-puffing and the effect of moving soliton-like coherent micro-puffing.

Abstract:
The analysis of the expediency of the use of FF-AGC, FB-AGC, MFC-AGC regulators in cold roll forming process control systems is performed by controlling the main drives of the rolling mill stands on power. The concept of combined control of leaf thickness by perturbation with the help of the FF-AGC regulator and intercellular tension on the deflection with the help of the FB-AGC regulator is considered. The MFC-AGC regulator is used as a top-level controller, since it most fully covers the dynamics of the entire rolling mill.

A Parametric Invariant System for Crystalization Processes
Authors:
Pranav Roy, Rohan Chaudhary, Shivani Charan, Soham Kishore
Abstract:
The solution of the problem of invariance implies the definition of such a structure and parameters of the control system, in which the quality of the functioning of the system does not depend on perturbations. The necessary and sufficient conditions for invariance in the output for linear stationary dynamical systems to arbitrary external perturbations are obtained. The processes of growing large-sized scintillation single crystals belong to the class of multidimensional multiply connected control objects whose parameters under industrial production conditions are subject to change. Therefore, for crystallization processes, a control system is needed that ensures the preservation of its main characteristics when the parameters of the control object change over a fairly wide range. A synthesis of a system with parametric invariance of the output for controlling the growth process of a single crystal has been carried out. It is shown that the synthesized control system is able to suppress perturbations characteristic of growth systems.

Integral Newton Laybytska and Second Integral Theory About The Medium
Authors:
Dennis Peters, Dieter Lange, Hermann Scholz, Daniel Fuchs
Abstract:
The definition of an integral in a narrower sense is considered in the article than the Riemann integral. We can assume a new definition, in a sense, a special case of the Riemann integral. In the integral Riemann sum, the function is computed on the left (or right) points –partition of the segment of integration. The basis of the Newton-Leibniz integral lies in the definition of the primitive, differential function, and a special way of selecting points on the partial segments of the partition. The advantage of this approach is the Newton-Leibniz formula and the second integral theorem on the mean, which follows from our theory. The proposed scheme deepens the understanding of the nature of the integral.

Abstract:
The synthesis of SAUs was carried out by the process of biochemical water treatment. As the process of biochemical water treatment involves several complex processes, the synthesis of SAUs was carried out for the three main contours. The control values were determined: the supply of active sludge and air, and also the perturbing factors were determined: the amount of waste water entering the aerotank Q, the volume of waste water in the aerator V, the concentration of pollutants in the flow of Si water. The synthesis of the control system of the compressor and pump units was completed. The controllers are selected and their settings are defined. The performed simulation of dynamic processes in SAU confirmed the effectiveness of the proposed control laws.

Authors:
Ryan Hill, Sam Wilson, Matthew Scott
Abstract:Abstract:
The methods of increasing the accuracy of calculating the quality of service characteristics in a network with self-similar traffic are investigated due to a more accurate determination of the Hurst coefficient depending on the parameter of the Weibull distribution form. Since self-similar traffic (the time interval between applications) is best described by the Weibull distribution, it is for him that a new formula for calculating the coefficient of self-similarity of traffic is obtained. In this case, the calculation of the quality of service characteristics can be performed on the basis of the Norros formula, which is valid for the model fBM / D / 1 / .

Bandwidth Artificial Extension for Speeches in Telephony Using Phonetic Classification
Authors:
Imanuel Christiansen, Jaspar Petersen, Leonardus Johansen, Bengt Jakobsen
Abstract:
This work presents a new strategy to implement artificial bandwidth extension (ABWE) systems for speech signals applied to the public switched telephone network (PSTN). Specifically, here is proposed a strategy based on phonetic classification aiming to satisfactorily represent segments of speech with energy concentrated at high frequencies, surpassing results presented in the literature. To this end, attribute selection techniques applied to limited band speech signals are investigated, improving the classification in broad group phonetic (BGP) with emphasis on the discrimination of phonemes belonging to the fricative phonetic group. Additionally, this work is also discussed the integration of the ABWE system proposed in automatic speeech recognition (ASR) systems applied to the PSTN. In particular, aiming at enhancing ASR in PSTN, the steps of speech signal attribute extraction as well as the stage of construction of the acoustic model are developed based on synthetic broadband (WB) signals estimated from the enhancement of narrowband (NB) signals using ABWE. The results obtained highlight the subjective quality of the reconstructed speech signals and gain in the performance of the RSA, confirming the effectiveness of the strategies proposed in this research.

Abstract:Abstract:
This work deals with the separation of audio signals from which has a priori information, aiming to separate the instruments in a mixture composed of harmonic and percussive elements. Among the usual techniques, the Non-Negative Matrix Factor (NMF) method was chosen, since the quality of the separation of this technique is not conditional on the number of available observations. The experiments are implemented in Matlab environment using the Kullback-Leibler divergences and Itakura-Saito. The results indicate significant improvement in contrast to other methods

Authors:
Dimitur Nazarov , Ekaterina Larin , Anastasiya Gavrilov
Abstract:
In work the criteria of diagnostics of screw connections in ultrasonic tomographic equipment are described. The solution of the problem of increasing the duration of the period from the moment of detection of a defect in a screw connection is given before a decision is taken to localize the emergency situation. Modern control over the change in the ambient temperature, the temperature of the screw connection and the load currents makes it possible to detect the initial moment of weakening of the screw connection contacts, regardless of the level of excess of the admissible temperature of the screw connection. Timely detection of the weakening of the contact connection increases the time period for decision-making by the dispatching personnel.

Authors:
Luisa/Louisa Maier, Johanna Köhler, Emilie Herrmann
Abstract:Abstract:
A comparative analysis of two shadow methods for obtaining a surface profile in an optical microscope is performed. The first method is classical; it is implemented in a double Linnik microscope. The second method is proposed by the authors, it is based on the use of a shadow from a bright source without the use of an optical system. The paper describes a new method, a scheme for its implementation in the form of a module for an optical microscope, a module for a shadow method, and the results of an experimental study of two methods. It is proved that the proposed shadow method has advantages: for equal errors in measuring the height of the profile, it has a larger range of measurements and a substantially lower cost.

On the Scientific Establishment of Environmentally Safe Return in the Plast of Conditional-Plastic Water of Oil And Gas-Condensative Fertilizers with Reception of Iod
Authors:
Christian Accardo, Arianna Spallanzani, Beatrice Morucci
Abstract:
Investigations of the reaction of ozonation of iodidones in mineralized waters in the presence of bromine ions, iron, the regularities of changing the degree of iodine formation from acidity, mineralization of water, changes in the concentration of these ions, the time of ozonation, and the molecular ion ratio of reagents. In particular, with an increase in the time of ozonation, the degree of formation of ozone initially increases, reaches the maximum value under these conditions, and then decreases. Such patterns are observed with decreasing the acidity of the medium, changes in the concentrations of iodine ions, and an increase in the molecular ion ratio. It was established that with the increase of the contact surface between phases the degree of iodine formation increases, indicating mass transfer as a limiting step of the ozonation process. On the basis of experimentally found changes in the concentrations of the reagent, the rate of the ozonation reaction is estimated. The obtained research results can be used to create a more environmentally friendly technology for the extraction of iodine from the accompanying flood waters.

General Electric Color with the Fitness of Physical Function of Hypervalent Interaction
Authors:
Yu Dongbang, Yun Du, Han Ryu
Abstract:
The paper presents solutions to a number of important scientific problems, each of which has not only a special technical but also a natural phenomenon. First of all, the physical phenomenon of a hypervalent interaction, which arises or may arise between structural links in physical and technical dynamical systems with lumped parameters during their continuum motion in phase space, is revealed and described. At the same time, in the topological space of such dynamic systems, the notion of a typical elementary link is introduced as the smallest and structurally indivisible particle. Their set forms one of the sets of this space, and the plurality of subsets of this set, which determines the topological structure on it, complements the pair during its formation. On the basis of such structural units and their inter-valence interaction, two basic outline provisions are introduced into the theory – the principle of the typical elementary units and the principle of their hyper-connectivity. The first determines the rule of division and construction of dynamic systems, and the second – the formation of a topological structure in the event of a subsequent generalization of such objects. The last circumstance allowed to form a generalized structural scheme of a dynamic system, regardless of its physical origin and purpose. The above remains valid for both physical and technical systems of homogeneous or mixed physical nature of their typical elementary units. The aforementioned theoretical foundations are used during the study of one of the classes of electrical systems – electric circuits. This allowed us to introduce and formulate the notion of a generalized electric circuit as an abstract object, which deductively covers all other classes of electric circles. On the basis of the mathematical analysis of the structure of the Lagrange Maxwell equations and taking into account the phenomenon of the hyper-valence interaction, differential equations of the motion of a generalized electric circuit in the first and second systems of generalized electric coordinates were obtained, and its generalized structural and electrical schemes were constructed. Among the known basic elements presented here is the highest level of generalization and allow formalizing the process of mathematical and physical identification of the above-mentioned dynamic systems in the event of their arbitrary physical nature.

Abstract:
Modern information of operational observing the condition of agrarian lands provide an opportunity to provide the appropriate quality control of the implementation of technological operations using modern information technology mechatronic and robotic control systems associated with quality control processors for technological operations, which in the current context of their development have been called “smart” or Smart machines (smart machinery). Such “smart” machines with operational monitoring sensors will become agricultural land at all stages of production of agricultural crop production: basic cultivation, sowing (planting), at the stage of crop maintenance during the growing season and harvesting. “Intelligent” machines “adapt” to the agrobiological state of the soil environment based on information from sensors on the agrobiological state of the soil environment. An important task of operational monitoring of agricultural lands is the so-called “management units” of territorial units with similar parameters of spatial heterogeneity, where similar crop cultivation technologies should be used. These technologies are the basis of the decisionmaking systems decision making system, which allows for the adoption of effective operational decisions based on operational data on the agrobiological state of the soil environment. In this sense, the development and use of a fundamentally new class of agricultural machines – technical systems of operational monitoring of the variability of the agrobiological state of the soil environment of agricultural lands becomes relevant. A model of optimal quality management of a technological operation based on operational data from a technical system of operational observing of the situation of agrarian lands depending on the agrobiological situation of agricultural lands is formulated. This model provides an opportunity to ensure the proper efficiency and quality of the implementation of technological operations in agricultural production.

Abstract:
The paper proposes a theoretical method that calculates the repulpatory apparatuses for washing dispersed tools. Optimization of mass-exchange and kinetic parameters of each stage of the cascade will significantly improve the purity of the product and reduce energy and water consumption. A detailed analysis of the kinetics of washing in conditions of differentiated intensity of mass return was based on the rational distribution of the time of stay (contact) of the interacting flows at the stages of the cascade. Multistage rinsing with differentiated flow rates is an effective water and energy saving system. A typical example of this process concerns the purification of raw resources. The cascading method presented in this paper uses the equations of material stability and kinetics of the process with inequality of productivity coefficients of each level of washing.

Basic Approaches and Features of the Tuman Computers Use
Authors:
Elin Asplund, ludvig Nordgren, Philip Forss
Abstract:
The basic approaches that are used in the construction of modern cloud services are considered. It is shown that cloud services are characterized by mobility, lower aggregate financial costs of organizing data center infrastructure, wide opportunities for automation of network resources and flexibility in working with projects in the context of reorganization of the system. The analysis of advantages, drawbacks and actual areas of application of private, public and hybrid cloud services is carried out. Also, the work outlines features of the use of basic cloud service delivery models: the HaaS model, the infrastructure model (IaaS), the PaaS platform model, and the SaaS software delivery model. The efficiency of measures to support the reliability of the cloud service service is considered, including the provision of the work of servers of the service infrastructure in real time and reliable data storage on the servers. To this end, an algorithm for loading the infrastructure of cloud service during active work with subscribers is constructed and the advantages of using the circuit of balancing hardware resources of the network are shown. In order to ensure reliable data storage in the event of an emergency, it is proposed to use a code that corrects errors; also, the advantages of encoding over simple duplication are calculated, as a function that determines the relationship between the number of additional servers in both cases. The analysis of parameters characterizing the efficiency of services of this type and evolution of cloud computing tendencies is carried out. The advantages and disadvantages of using foggy and rosy computations as a stage of cloud computing development are determined. It is shown that fuzzy calculations can increase the mobility of cloud computing, but within the framework of this approach, the user’s dependence on the reliability of Internet communication remains. The methodology of rosaceous computing is shown as the application in the cloud service architecture of the function of storing “hot” data on the drives located in the user’s internal network and operating in the mode of the FTP servers of the hybrid cloud from the division of resources into public (community servers) and private, and also with the anonymization of hardware resources. The analysis showed that foggy and depressed services are similar to cloud services, but in this case aspects of network infrastructure security, confidentiality of data, anonymity of resources and instantaneous service elasticity are of greater importance.

Method of Displaying Voice Signals in the Task of Recognizing the Speaker
Authors:
Qendrim Pocoli, Ledina Mishaxhi, Kaltrina Idrizi
Abstract:Abstract:
Most cognitive services use speech signals as a source of information, namely: recognition of emotions, speech and identification of the speaker. An actual problem is the creation of a general approach to the reflection of speech signals, devoid of the shortcomings of existing methods of classification in the problem of recognizing the speaker. A new approach to the reflection of linguistic signals as vectors of attributes distributed in time is proposed with the use of a recurrent neural network. To search for an alternative function of displaying the signs of a speech signal, a recurrent neural network consisting of a chain of bi-directional long short-term memories is used in the work. The Euclidean distance is used to simplify the process of equalizing the samples of speech signals. To adjust the weights of the recurrent neural network, the triplet loss approach is used, which is successfully used for face recognition. It has been shown experimentally that using the proposed approach allowed reducing the speaker EER recognition error by 7.5% in comparison with the modern i-vector approach with the dimensionality of the mapping vectors 16 and 100, respectively, for speech signals with a duration of 2 s.

Method of Normalization of Photography of Automobile Range after its Recognition by Video Monitoring Means
Authors:
Kanan Aliyev
Abstract:Abstract:
One of the fastest and most reliable object detectors is the Haar Detector. However, this type of detector in the case of its use for detecting car numbers does not distinguish the exact boundaries of the number. The exact allocation of borders is necessary for further character recognition. Existing algorithms of normalization in many cases cannot cope with the task of precisely allocating the limits of the car number, which reduces the likelihood of correct identification of the number. This paper describes a method for normalizing the image of an automobile number after it was detected by the Haar detector for further character recognition of the number.

Abstract:
Infringement of information security of computer networks can be caused by a multitude of different reasons: the presence of vulnerabilities in operating systems and applications, the implementation of malicious security policies, incorrect configuration of hardware and software, mistakes made in the configuration of security mechanisms, etc. Thus, when designing and operating a computer network, the task is to check whether the security policy provides network configuration parameters and security mechanisms that require the level of security. The work is devoted to the development of an approach to the analysis of the security of computer networks based on the construction of common attack graphs and the development of a system of security metrics, used to assess the level of security of computer networks at different stages of their life cycle.

Abstract:
The task of the synthesis of automatic control systems (ACS) is one of the most complex tasks of designing systems. Such problem is actual for automatic control systems of steam turbines of power units of nuclear power plants. The K-1000-60 / 1500 Steam Turbine presents a series of most powerful domestic steam turbines with a nominal capacity of 1000 MW and a frequency of 25 Hz, which are successfully operated on many other ACSs. Efficiency and trouble-free operation of steam turbines largely depends on the quality of their control systems. The most important task of controlling the steam turbine K-1000-60 / 1500 of the NPP unit is the task of stabilizing the rotor rotation frequency, which is performed by the system of automatic frequency control (AFC). To ensure the safe operation of the turbine after the perturbing effects of the AFC, the frequency deviation from its nominal value in the dynamic modes should be limited to the specified limits, and after the interruption of the effects it should quickly and smoothly return to zero. The article is devoted to the development of a mathematical model of steam turbine as a management model.

The questions of parallel
organization of modeling processes of dynamic problems of large dimension,
which are described by systems of ordinary differential equations, are
considered. Allowance for the sparseness of the coefficient matrices makes it
possible to significantly reduce the complexity of the numerical realization of
dynamic models, since each step of integrating such problems, as usual, reduces
to performing matrix or matrix-vector operations, the optimal realization of
which determines the possibility of obtaining an efficient solution using
parallel computers. Particular attention is paid to the methods of compact

Abstract:Abstract:
In stationary conditions, the
measurement of AP in synchronous manner with three methods that were
implemented in one measuring system, the accuracy of the results is
approximately the same. However, taking into account the peculiarities of the
formation of signals, which are used to evaluate the parameters of systolic and
diastolic pressure, it can be argued that the results of the oscillometric
method with the reference channel under the non-stationary conditions (presence
of motor artifacts, cases of unexpected tone) will be more accurate and reliable.
Therefore, further research is being carried out on the measurement of APs
synchronously with different methods in the presence of motor artifacts, as
well as comparison with measurement methods without a cuff. The paper presents
the system of noise-proof measurement of arterial pressure by
tachoscillographic and oscillometric methods. The results of experimental

a capacitive sensor, a secondary digital converter with digital output, an
optoelectronic information signal transducer, and a processing unit for
recording and measuring information. A model optoelectronic transducer of
information signals is developed and manufactured. The principle of operation
and algorithm of the converter operation are described. At the current model of
the converter, experimental studies have been carried out, which confirmed its
main technical characteristics. The maximum data transmission distance using
the converter is 30 meters. The current consumption of the converter in the
continuous mode of transmission and data was up to 600 mA at a voltage of 5 V.

to reconcile the efficiency of all elements of the system both in the
accumulation of contaminants in the reversible cycle, as well as in their
removal in the treatment devices. To ensure the nonprofit operation of the
system, it is necessary that the accumulation rate of the individual components
of the contamination in the cycle is compensated by an adequate speed of
cleaning of the circulating water. The use of circulating water supply systems
in the unproductive mode leads to an increase in the concentration of pollution,
the balance of which should be ensured by special measures and differentiated

self-shaping of its cutting microrelief, i.e. on the process of self-sharpening
of cutting grains. Recommendations are formulated on the choice of geometric

Abstract:Abstract:
The purpose of the article is
to improve the method of an inclined half-plane for measuring the modulation
transfer function (MPF) of a digital camera. The method of the inclined
half-plane consists of forming an image of the interface of the intensity
difference, the direction of which is a small angle with the direction of the
columns of the matrix receiver of radiation. In this way, the vertically
oriented edge (along the receiver columns) allows for the horizontal function
of line scattering on the radiation receiver. In this case, the response of
each line forms different values of the scattering function of the edge
through different phase values. It is determined that the method of an inclined
half-plane allows to quickly obtaining an IPF camera with a matrix receiver
using one image.

Abstract:Abstract:
A comparative analysis of two

paper describes a new method, a scheme for its implementation in the form of a
module for an optical microscope, a module for a shadow method, and the results
of an experimental study of two methods. It is proved that the proposed shadow
method has advantages: for equal errors in measuring the height of the profile,
it has a larger range of measurements and a substantially lower cost.

Authors:
Özlem Erkin, Muhammed Durak, Ahmet Eren
Abstract:
Most optic access networks
are based on fiber-optic linear paths (FOLP) with a throughput of 10 Gbit / s
optical channels. Improvement of the functional characteristics of FOLP can be
accomplished by various methods, namely: by modular, spatial and polarization
multiplexing with the use of new types of optical fibers with an increased
working band; multi-positional modulation formats for optical signals and
high-density spectral multiplexing of optical channels. The expanded functional
parameters of fiber-optic access networks and ways to increase the efficiency
of the operation of fiber-optic linear paths by using multi-level modulation
formats, multi-core optical fibers and spectral sealing of optical channels are
determined.

Rabia Şen, Mustafa Reis, Hakan Terim
Abstract:Abstract:
The analysis of Nano sized
fractions formed during welding by test electrodes with improved
sanitary-hygienic characteristics, namely, with reduced content of chromium
(VI), was carried out. Evaluated the emission of nanoparticles into the air of
the working zone and the chemical composition of nanosized fractions during
welding with high-alloyed brands of research electrodes with a rutile type of
coating (five grades) and different types of binding with reduced chromium
content (VI). It has been established that welding with experimental electrodes
is accompanied by a considerable emission into the air of the working zone of
particles of the nanoparticle, which differs with the dynamics in time of the
total concentration of nanoparticles, their fractional distribution and the
content of nanosized metals. In the process of welding all the experimental
electrodes in the air of the working zone, nanosized metals were found: chrome,
manganese, zinc, iron, cobalt, copper, silicon. Experimental electrodes at welding
showed a tendency to reduce the emission of air into the working zone of
nanosized metals, in particular, chromium, which corresponds to a decrease in
the content of this element in their composition.

Authors:

Abstract:Abstract:
The purpose of the article is
to improve the method of an inclined half-plane for measuring the modulation
transfer function (MPF) of a digital camera. The method of the inclined
half-plane consists of forming an image of the interface of the intensity
difference, the direction of which is a small angle with the direction of the
columns of the matrix receiver of radiation. In this way, the vertically
oriented edge (along the receiver columns) allows for the horizontal function
of line scattering on the radiation receiver. In this case, the response of
each line forms different values of the scattering function of the edge
through different phase values. It is determined that the method of an inclined
half-plane allows to quickly obtaining an IPF camera with a matrix receiver
using one image.

Abstract:
This paper proposes an

Through this syllabic classifier, we automatically obtain the classification
and division of the syllables of any word in the lexicon. We also present the
rules for the identification of clitic groups necessary for the establishment
of prosody of synthesized speech, since this type of prosodic constituent
forces the resilabination of internal words to these groups. The use of
syllabic contexts and clitic groups in the choice of the best target unit
shows, in informal listening tests, a sensible improvement in the naturality of
the synthesized speech.

general situations and in other very restricted ones. The results of the tests
showed that the rules of alternation of vowel sounds, proposed in this article,
solve most of the problems concerning the differences between names and verbs.

Three main areas of the use of reconfigurable calculators (RC) are identified
in the tasks of creating specialized reconfigurable computing systems. The
general scheme of the low-level model of arbitrary reconfigurable CS is
constructed. The main structural elements of RC are defined: host; reconfigured
array of logical (functional) elements based on FPGA or elements with
reconfigurable structure; memory of the configurations of the reconfigurable
array of logical (functional) elements. It is shown that the common elements of
the computing system model are test devices, load generators, monitoring

Abstract:
The article describes the
principle of maximum speed of information in the diagnostic process. It is
shown that in order to provide a given reliability and to reduce the losses
that may arise due to poor quality diagnostics, it is necessary to apply
measurement methods that allow the structural excess of the measuring part of
the scheme to be used. An approach is developed to increase the reliability of
control and accuracy of control for technical diagnostics, which is achieved by
correction of thresholds in accordance with the calculated coefficients – their

Mathematical
Model of a Multi-Frequency Picorecondous Vibrational System with External
Capacitive Mems Control
Authors:
Alya Danial, Alex Abdullah, Hani Ahmad
Abstract:Abstract:
Generated oscillations is one
of the most important characteristics of piezoresonance oscillation systems,
which are increasingly used both in telecommunication systems where they are
traditionally used to form highly stable signals and their processing. Two
control problems are present: the first is to ensure the invariance of the
generation frequency with respect to the influence of destabilizing factors
(minimization of controllability), which is typical for reference signal
generators and quartz filters; the second is to provide a given control
characteristic (quartz FM modulators). The controllability characteristics
acquire a special significance in the case of multifrequency excitation of a
quartz resonator, where, in most cases, there is a need to simultaneously solve
two problems: ensuring invariance with respect to one frequency and forming the
necessary control characteristic with respect to the other. The use of
controlled piezoresonance oscillating systems with external capacitive
microelectromechanical control (MEMS) for solving control problems in
multifrequency generators is promising for today. An adequate mathematical
model of a controlled piezoresonance oscillatory system with external
capacitive microelectromechanical control is developed. Recommendations are
formulated to optimize the characteristics of the generator control.

Abstract:Abstract:
The known means for
controlling the moisture content of grains using the method of high-frequency
measurements of relative dielectric permittivity are not protected from the
main perturbing factors (unstable dielectric losses, porosity and granulometric
composition), therefore, have measurement errors which far exceed the declared
values. The article describes an improved version of a dielectric moisture
meter, which has a fairly good metrological characteristics due to the minimum
number of structural elements, due to the use of the method of determining the
capacitive component of the current of a sensitive element, which is located
through the informative parameters of a measuring transducer consisting of
successively connected exemplary and sensitive elements.

environments are presented based on the developed theory of the emergence of
material energy redundancy and its development in pursuit of the level of the

the main one in the presentation of the theory of the method is considered. The
method of control allows describing the thermodynamic state of the object of
regulation on the basis of the description of the whole complex of energy
states of the interaction of its parameters in a single control system, which
in turn allows controlling effect on the object of regulation within the specified

Construction
of a Wide-Circuit Antennas Based on A Double-Point Frame Radiator
Authors:
Marie Sefcik, Nikol Woyzeck, Jitka Rovnák
Abstract:
The work is aimed at
increasing the efficiency of mobile short-wave radio systems, creating
small-size broadband directional antennas for installation on mobile objects.
The principle of constructing a wide-band antenna is proposed. The original
radiator in the form of a loop antenna with arbitrary two-point excitation is
investigated. A method for determining the input resistance is described. This
method is based on the results of measurements of the input resistance of the
same antenna for single-input excitation and various loads at its other input.
For calculation and analysis of the input resistance of the frame radiator with
two-point excitation, its representation is used in the form of two open
frames, combined with each other. Simplified engineering relationships are
obtained, which allow analyzing the input resistance of the frame radiator for
arbitrary two-point excitation of its inputs. In these relations, variables
characterizing the input impedances of the frame emitter in the case of a
“short circuit” and “idling” of one of its inputs are used,
which, in turn, can be easily determined experimentally. Using the experimental
results, the following is revealed: when the quadrature excitation of the frame
radiator is equal in amplitude at two opposite points, the level of the active
component of the input resistance of the antenna increases; the limits of the
change in the input impedance of the antenna are substantially reduced, which
makes it possible to provide broadband matching of the antenna with its
relatively small overall dimensions. This property of the frame radiator with
two-point excitation allows us to formulate an assumption regarding the
dependence of the input resistance (resistance of radiation) of a small-sized
antenna also on the method of its excitation, and not only on the overall
dimensions and geometric configuration of the radiator. Directions for further
research in this area are optimizing the shape of the emitter, increasing the
excitation points and choosing the optimal locations, investigating the
directivity characteristics of such an antenna, and developing a wide-band
antenna excitation device.

Increase
of Information Transparency of Transmission
Authors:
Baard Pedersen, Abbelone Olsen, Eeva Nielsen
Abstract:
A method is proposed for
secondary coding of a transmitted non-equally probable primary alphabet in
order to ensure equiprobable transmission of a symbol in the channel with an
accuracy of one percent. The number of different code combinations (“bank”
of the code words of the symbol) is determined to ensure equiprobable
transmission of codewords. To reduce the transmission time, the use of timer
signals is suggested, the optimal length of the timer codeword is determined.
It is shown that, with an increase in the implementation interval (m) for S =
const, the number of possible signal structures grows. At the same time, the
information capacity of one codeword grows. The information capacity of one
niqvist element increases as m increases (up to m 5), and at m
> 5 starts to decrease. For each “m” the information capacity
increases with “S”. It is established that the choice of the
parameter “S” is expediently limited by the value S = 8, since at S
> 8 the probability of mistaken reception of one modulation moment
increases, even in the “good” state of the channel. This is due to
the fact that for S > 8 the value of the information capacity of one
codeword increases, but the losses grow even faster due to an increase in the
error probability.

Abstract:
This paper proposes a new technique of
initialization of processes of blind separation of speech signals in the
frequency domain that focuses on their application in reverberant environments.
The developed method employs directional arrangements of microphones,
resynthesizing the signals through sinusoidal oscillators and Wiener’s work. As
a method of improving the initial solution obtained, the algorithm for
exploring high-order statistical dependencies between frequency components was
adopted. The results obtained with the proposed method are compared to those of
other methods already consolidated in the literature. The experiments were
conducted in several acoustic environments, both simulated and real, in which
mixtures of voice signals were recorded by a set of microphones

which can enhance instrumental characteristics, such as frequency resolution
and accuracy of determining the frequencies of the signal spectrum without

Abstract:tract:
Typical ways of controlling
water level of a water object are presented. In the study of the consequences
of reducing the level of surface water of a Lake, the regularity of modulation
of the frequency of the internal fluctuations of the water basin by the
function of depth was revealed. The method of direct measurement of water
level, based on the solution of the inverse problem, is proposed. Also, a
method for remote measurement of the level that uses the vibration analysis of
the bottom of the seich origin is proposed. Remote measurement allows
multi-channel monitoring using time, frequency and space densification of
vibrations of the bottom of different reservoirs. It is advisable to remotely
measure the water level of remote water objects, which information may be
limited. In addition, it is proposed to use a certain pattern for other
engineering tasks – seismic intelligence, increase of power generation of
hydroelectric power stations, control of displacement in fragmentation of
seismic faults.

Authors:
Batuhan Özbek, Emre Örs, Duygu Gümüş
Abstract:Abstract:
The application of phase
methods for measuring distances is an accurate method. But its use in conductor
lines has certain limitations. The presence of an undefined parameter of damage
or change of line parameters leads to the appearance of an additional phase
shift angle. The application of the phase-frequency approach to the reflection
signals analysis reduces the influence of these factors on the accuracy of the
distance determination.

Authors:
Bo Sòng, Qiang Zhèng, Mei Xiè
Abstract:
The formation of
three-dimensional graphic images is quite a labor-intensive process, since
complex calculations taking into account a large number of parameters are
performed for each point of the scene. With increased screen resolution and the
use of complex lighting models, time constraints are further intensified. In
this regard, the issues of increasing the productivity of the formation of
highly realistic graphic images are important, since it significantly expands
the field of application of computer graphics tools. A method for increasing
the productivity of three-dimensional image formation based on reverse ray
tracing, line and block linear interpolation, smoothing filtering, which allows
obtaining realistic images in an acceptable time, is proposed.

Abstract:Abstract:
The development of

the construction of telecommunication networks, operators relied on existing
statistics on the load, the range of services and user demand, it is now
necessary to take into account, first of all, the “future” demand,
the prospects for increasing the volume of traffic, changes in the composition
of user devices and, accordingly, the types and parameters generated it
traffic. In the recent past, monitoring traffic was a relatively simple task,
in connection with the development of telecommunication networks and the
complication of their topology, total traffic can no longer be seen from one

Abstract:
This article discusses the
solution of the metrological task of super-redundant measurements of the
resistance of resistors and resistive sensors in terms of obtaining not one,
but a number of basic equations of redundant measurements in practical use,
commutation or search of all the variants of connections of three resistors –
Rx, R01 and R02, and their parallel connection to the input resistor Rin the
measuring channel. If in message 1 it was shown the possibility of determining
the parameters of the measurement channel transformation function, its input
resistance, the actual values of the resistors normalized in resistance, the
error in computational data processing, then the message focuses on determining
the set of real numbers of the sought physical quantity. This metrological task
is solved with a linear transformation function of the measuring channel. The
essence of the method of super-redundant measurements and its mathematical
models are described taking into account the influence of the input resistance
of the measuring channel on the final result of measurements. The corresponding
equations of excess measurements of the required physical quantity and the
technical solution of the resistance meter, realizing the method of
super-redundant measurements, are given. The work is of interest for

Before modern manufacture
there is a problem of decrease in cost of repair work and operation of products
taking into account maintenance of the maximum safety. The development of
surface improvement technologies is associated with phenomena occurring in the
contact zone of parts, taking into account the strength characteristics of

friction surfaces, it is possible to significantly increase the life of the
mechanism. Thus, the task of friction, lubrication and wear comes to the fore. The

the effectiveness of the use of natural additives providing compensation for
the dimensional wear of machine elements are presented.

Carit Mogensen, Benete Frandsen, Ilsabeth Iversen
Abstract:
The project is aimed at
addressing an important application that acted acutely within the framework of
the ATO, as well as providing protection against unauthorized attacks on
information on the territory, through the use of unmanned intelligence systems.
The indicated means use two defining principles – radio control, and the
transmission of television information by radio channels. The existing fleet of
unmanned flying and mobile vehicles uses both classical and modern radio data
transmission equipment using noise immunity (FFSS, ADT, GSM, CDMA, etc.).
Therefore, the classical well-known means of Radio-electronic struggle (REB),
which are at the present level, are not capable of ensuring the fulfillment of
two principles and tasks: – suppression (failure in the management of the
trajectory of motion), and most importantly, blocking the transmission of
tele-information in real time, precisely for signal-code design of signals, use
of orthogonal processing and secrecy of transmission on random channels of “broadband
noise-like” communication channels. It is proposed to develop and order
the production of the newest REB based on the use of the original principles of
the phase-frequency theory of measurement and transformation of radio signals.
A description of the new technology for constructing a DAC-ADC and a
programmable conversion characteristic are described. The possibilities of a
new approach in the construction of real measuring and generating systems are
shown. At the heart of the new type of transformation is the use of the
Attenuator-divider. Another area of application of the KTV is the creation of
high-speed and high-speed frequency meters based on the method of coinidence.
Practical tests are given and the real advantages of the method are shown. In
conclusion, a description of the designer of the laboratory complex for the
course “Physics (Electrical and magnetism)” is given, and it shows
its use not only for initial research but also for research purposes.

Investigation
of the Subject Management Efficiency on the Transmission of Information in
Networks of The Standard Wi-Fi
Authors:
Moritz Schwarz,, Anton
Zimmermann, Mia Braun
Abstract:Abstract:
In this paper, the effect of
the Doppler frequency shift effect on the main quality criterion of the
transmission channel for 802.11 Wi-Fi wireless networks has been studied. First
of all, an analysis of wave propagation characteristics in the 2.4 GHz band has
been carried out, and it has been established that the Doppler Effect depends
on the characteristics of the carrier frequency of the signal and the speed of
the receiving equipment. Therefore, any transmission systems with OFDM
modulation are sensitive to displacements in space. The Doppler frequency
offset analysis, as a negative factor in the transmission of information, and
for methods that allow the use of this phenomenon to detect objects and their
position in space, is performed. This made it possible to determine the optimal
conditions for research and to offer a network structure. After conducting
experimental studies, it was discovered that any movement of transceivers of
802.11 standards in space has a significant effect on the effective rate of
transmission of information in the channel. The greatest change in the
efficiency criterion begins at a speed of 1 m / s or more.

Increasing the Function of Thermostatic Converters
Authors:
Hwang Gong, Hyeon Gwak, Im Gyo, Kang Gu
Abstract:
The method of increasing the speed of temperature measurement by using two thermo-resistors with preheating and subsequent averaging of their signals is proposed. The heating of the thermistors is carried out by alternating current of high frequency, which allows controlling the resistance of the thermistor during the heating. To select a constant voltage component on the thermistor, which is proportional to the resistance value of the thermistor, and therefore the measured temperature, a low pass filter is used. The developed temperature meter provides a measurement accuracy of 0.1 ° C at a measurement time t = 2τ, where τ is the time constant of the thermistor. The device can be used to measure temperature at two different points, as well as to measure their difference.

Microprocessor Implementation of the Means for the Vaylet-Diagnostation of the Brake Circle of Frequency-Circular Asynchronous Electric Driver
Authors:
Klaudia Ignasiak, Anna Gajdos, Magdalena Filak
Abstract:
Reliability of the electric drive is of paramount importance both in industry, in agriculture and in electric transport. And the basis for modern automated energy-efficient production is a frequency controlled asynchronous electric drive, which is used in those mechanisms where adjustment of coordinates of speed, position and moment in a wide range is necessary. Due to smaller mass-overall dimensions and high energy efficiency, compared to other types of electric drive, frequency-driven asynchronous electric drives are gaining in popularity, and their applications are becoming more and more widespread. Considering that the failure of a frequency controlled asynchronous electric drive in general or its components can lead to damage to production equipment, stopping of production, resulting in significant material damage, and may endanger the life or health of the work personnel or passengers, in the case of electric transport, the creation of devices that allow the diagnosis of a frequency-controlled asynchronous electric drive or their components is relevant. In the work microprocessor implementation of a means for wavelet diagnostics of the brake circle of the frequency-tested asynchronous electric drive is proposed. The algorithm of functioning of the diagnostic tool, and its hardware part, is necessary for construction of the diagnostic system.

Abstract:
An integral part of the modern diagnostic and treatment process in any medical institution is a complex stationary electronic medical equipment and equipment. A particularly topical issue for massive stationary equipment (tomographs, X-ray machines, life support systems, monitor systems, ultrasonic diagnostics devices, lithotripters, KVF equipment, etc.) that consumes more power, or in the network of which a significant current flows, is the mechanical weakening of current-conducting elements in system of power supply of medical equipment. It was proved that the attenuation of a current-carrying compound leads to a decrease in its heating constant τ, and the value of the constant heating determines the time of establishment of the thermal regime of current-carrying joints. According to the experimental data obtained in the work, graphical dependences of the change in the temperature of current-carrying compounds in electromedical equipment are plotted against time, which confirm the theoretical conclusions.

Efficiency of Extraction of Ions of Heavy Metals from Diluted Solutions by Ion Exchange Method
Authors:
William Forslund, Jesper Granath, Malin Renberg
Abstract:Abstract:
The processes of ion-exchange extraction of heavy metal ions on weakly and strongly acidic cationites have been studied. At concentrations of copper ions below 0.1 μg / dm3, their sorption does not occur on weakly acidic cation exchangers and at concentrations of 1 μg / dm3 on the strongly acidic cation exchange KU-2-8. At a copper concentration of 10-2 μg / dm3, copper is not sorbed when using mixed-action filters. Almost complete recovery of lead is obtained on strongly and slightly acidic cation exchangers, regardless of the concentrations of the initial solutions. When removing lead ions, the recovery rate increases. When using a 2M solution of hydrochloric acid, the desorption efficiency of lead ions reaches 100%. The degree of desorption of copper ions reaches about 90%.

Authors:
Ju Lín, Feng Hé, Lan Guō
Abstract:Abstract:
The experimental and theoretical investigations of the kinematics of the FFT-photo transformation in KCl + 1 mol% LiCl crystals in the charge have been carried out. It is shown that the mechanism of transformation of F centers into FA centers consists in the fact that when irradiated by crystals with light, the F centers move to an excited state and give electrons to the conduction band as a result of the electron-phonon interaction. During the lifetime of electrons in the conduction band, free halo vacancies due to diffusion are stabilized by impurity ions. Then, by attaching electrons, stabilized halide vacancies are converted into FA centers. It has been shown that in X-ray irradiated (γ-rays) crystals of adjacent halogen openings; the tunneling of electrons of excited F centers is only partially. It is proposed to use a tunneling effect to record information with a focused beam from a quantum light generator. You can delete the recorded information with a non-focused beam of light.

Authors:
Rachel Clark, Shannon Parker, Jess Rodriguez
Abstract:
The historiography of the main nodal moments of creation, formation and perspective development of the theory of phase-frequency measurements and transformations of radio signals (FHV and PR) is considered. New features of the decision of the principle limitation of measuring technique (classical), which consists in the fundamental contradiction, the impossibility of simultaneous increase and accuracy and speed of measuring transformations, are established. On the basis of the proposed adequate radio signal signals, it was possible to prove and practically realize frequency meters with a difference of 1 Hz in the time of measurement less than 1 millisecond, for signals with frequencies above 1 MHz, which is 1001000 times better than existing meters of leading manufacturers. A generalized table of the main directions of the application of the theory of FWB and PR is developed and presented. It is shown how the introduction of new approaches led to a generalized theory of quantum measurement transformations, which are possible not only for phase-frequency, but also amplitude parameters, with the principal definition of a key approach based on the method of coincidence. The main types of scientific and technical developments, as well as the creation of fundamentally new approaches, which allowed simultaneously increasing the accuracy and speed of measurements.

Abstract:Abstract:
Methods of recording
biopotential, generating brain, heart or muscle, have two main aspects of
application: medical and research. Medical diagnostics in the conditions of a
hospital is most often based on such methods of non-invasive studies, which use
cumbersome and costly equipment. At the same time, the actual problem is the
autonomous control and current monitoring of the human condition, both for the
purpose of timely detection of critical states, and for determining the
reactions to those or other influences. The work is devoted to solving the
problem of creating a research complex that includes a device for the
preliminary processing of bioelectric signals, their transformation into a
digital form and introduction to a personal computer for the purpose of further
analysis and development of algorithms for the functioning of a portable
autonomous electronic system, which is being developed for the first time.

Abstract:Abstract:
In this article, questions of
dynamic analysis of the executive link of the machine system are considered.
The calculation scheme is analyzed, consists of a spatial system suspended in
space on flexible elements. A mathematical description of the harmonic
oscillator is obtained, which is the executive link of the mobile machine. A
simulation model was created in the Simulink computer environment to study the
dynamics of the loaded executive link of a mobile machine. The model’s response
to forced harmonic oscillations is obtained, which has a quasi-random
character, with sinusoidal action. The result obtained allows us to assume that
oscillations with a wide frequency and amplitude spectrum that can cause
resonance of the elements of the technological system over a wide range of
frequencies arise in the operating unit of the mobile machine.

Abstract:Abstract:
The proposed new methods for
grinding both shaped and stepped surfaces of rotation with a cup-shaped
abrasive tool tipped onto the cone are considered. The methods make it possible
to increase the productivity and quality of the treated surfaces by rationally
loading the working surface of the circle along the contact patch. The increase
in efficiency can be achieved by controlling the distance between the axes,
choosing the angle of straightening of the butt. This allows you to increase
the size of the contact and the possible feed per line. The improvement in
quality is due to the release of the protected base form-forming point and the
appearance of a roughness in the form of a grid. New methods have better dynamics
and allow saving energy due to less time of machining and using of a smaller
overall machine.

Abstract:
The article considers the
choice of the measure of the difference in the results of filtering the
distorted discrete quantized periodic signals in the problem of searching for
optimal values of the parameter of the digital low-pass filter “simple moving
average”, represented in a non-recursive form. To compare the processed
signals, the measures of difference were chosen-the root-mean-square error, the
root of the root-mean-square error, and the mean absolute error. To execute the
experiments, a software library was created to generate periodic discrete
quantized signals, their distortion by means of fluctuation noise (noise) with
normal distribution, and subsequent filtering of the distorted signals. A
series of experiments was performed to generate distorted periodic signals with
different noise levels, and the values of the difference measures for the
filtered signals with different values of the digital filter parameter were
found. As a result of the comparison, a measure is chosen which is characterized
by high visibility of the optimum values of the digital filter parameter at
high noise levels.

Abstract:Abstract:
In this paper, the study of
the influence of the 802.11n WiFi network environment conditions under
interference, such as the combined channel, and the presence of a neighboring
channel for a non-licensed 2.4 GHz frequency band has been conducted. First of all,
an analysis of wave propagation characteristics in the specified range was
performed, and it has been found that there are currently many networks and
devices that interfere with the wireless channel, which greatly impairs the
effective transmission speed. An analysis of the conditions for the emergence
of interference noise, as a negative factor in the transmission of information.
This made it possible to determine the optimal conditions for research and to
offer a network structure. After conducting experimental researches, it was
established that the network operation in combined and adjacent channels
significantly reduces the effective transmission rate of information, while
leaving the network operational, but with a considerably low bandwidth. In addition,
the high level of power of the main petal spectrum from the interference
network brings significant obstacles to the transmission channel, while
increasing the delays, creating collisions and the appearance of a large number
of errors in the packets.

Authors:
Melike Kocak, Busra Younan, Ezgi Taşçı
Abstract:
For the first time on the
basis of bidirectional associative memory, the architecture and algorithms for
the operation of the non-directional discrete neural network associative memory
are proposed. The new memory can be restored by the input vector applied to any
of its input layers of the neurons, a set of N images that are associative to
the input information. This becomes possible due to the fact that the
architecture of the classical two-directional associative memory, which
consists of two sensory layers of elements whose neurons are interconnected by
pairs of weighted bi-directional connections with the corresponding weight
coefficients, is rebuilt by introducing into its structure additional (N -1)
sensory layers of neurons associated with the first layer of sensory elements
in pairs of bidirectional weighted bonds with corresponding weight
coefficients.

Abstract:Abstract:
Composite materials are
widely used in aircraft engineering, providing high strength, rigid, fatigue
and weight characteristics. The purpose of this work is the mathematical
modeling of the influence of constructive and technological factors on the
manufacture of products made of composite materials on their mechanical
properties in the event of violation of continuity during pulsed loads. The
paper uses an extended concept of the orthogonality of the resulting model: an
experiment plan, a model structure and structural elements of an orthogonal
model. For the experiment, a regular plan was chosen 23 × 43 // 32. The
influence of 6 factors on the strength and modulus of elasticity of composite
materials was modeled. The obtained models are stable, adequate and
informative. The use of the concept of experiment planning in modeling the
mechanical properties of composite materials fully confirmed the high
efficiency of this methodological approach and allowed to construct
mathematical models suitable for practical application. The obtained models
allow conducting an exhaustive analysis of the influence of the investigated
factors on the simulated functions, optimizing the values of factors by the
accepted criterion, predicting properties and solving other problems.

Abstract:Abstract:
The requirements for
materials for facing, having high operational properties, combined with
aesthetics and architectural expression, are constantly increasing in line with
the requirements of modern civil and industrial construction. Porous
non-metallic materials are the least resistant to atmospheric factors among the
stone materials that are most widely used in construction. The work is devoted
to the solution of the issue of increasing the atmospheric stability of
building porous nonmetallic materials by impregnating their surface with silicon
organic compounds of various compositions and assessing the stability of their
operational properties under the influence of atmospheric factors.

for combined food products on the basis of the Azov bull and a mixture of plant
ingredients were studied. The results of the studies confirmed the high
consumption properties of fish-plant semi-finished products and indicate high content
of their valuable proteins, mineral elements, in particular Calcium. The
results of researches of physical and chemical parameters of semi-finished
products testify to their high technological feasibility for use in the

CELP
Encoder with Vector Quantization Employing Quick Search
Authors:
Liam Garcia, William Turner, Luke Martinez
Abstract:
CELP (“Code-Excited
Linear Predictive”) encoders are based on the vectorial quantization (QV)
of the excitation. The use of QV allows to achieve good performance in terms of
bit rate and voice quality. By incorporating QV also to the encoding of the LPC
filter parameters, we can further reduce the bit rate of the CELP encoders.
However, the computational complexity involved tends to be very large. In this
work, we present the results obtained in a CELP coder using the QV applied to
the LPC filter. Using a conservative tree search technique we obtained a
reduction of up to 95% in the complexity for the quantization of LPC filter
parameters.

Abstract:
In this work we present a

coder proposed by Atal, whose form of excitation determination was not found in
any previous reference. The proposal is based on the use of several codebooks
to determine a linear combination of codewords referenced by a single index and
with simultaneously determined gain factors, replacing the excitation of the
conventional CELP encoder. The structure studied demonstrated, through
objective and subjective measures, the possibility of obtaining voice
synthesized with the same level of quality as that obtained with the
conventional CELP coder, with lower computational complexity.

Analysis
of the Mathematical Model of Erytrocyt in a Temporary T-Matrix Theory
Authors:
Felix Hoffmann, Luca Schäfer, Maximilian Koch
Abstract:
Mathematical modeling is the
most common method of research in science, and mathematical models themselves
adequately reflect and describe a research object, process or phenomenon
adequately. An important characteristic of the desired mathematical model is
its versatility when applied. The development of techniques, algorithms,
software and technical means for the analysis of the condition of blood cells –
erythrocytes on the basis of modern optoelectronic and laser technologies –
ensure high efficiency, accuracy and non-investability of research. However, for
the correct formulation of the scattering problem, one must take into account
the intensity and polarization of radiation, which is achieved by the
introduction of the Stokes vector parameter and the scattering light matrix. The
optical characteristics of the erythrocyte model were determined: scattering
coefficient, depending on particle size and refractive index, for developing
and analyzing the erythrocyte mathematical model based on the Stokes vector
parameter and the light scattering matrix.

A
New Method of Recognition of a Mobile Object with Three-Coordinated Seismic
Receiving of the Signalizing Means of Protection
Authors:
Aryan Chander, Raj Nara, Arjun Rai
Abstract:
Signaling seismic technical
means of border guarding (TMBG), based on one or more seismic receivers (SR) or
seismic sensors, which is a component of a seismic position guarding device,
may be considered as potential means for the protection of a temporary position
of observation. To protect a temporary position, it’s enough to apply one SR,
the radius of detection of a moving object (MO) – a person who in modern means
is 3050 m, and a vehicle – an order of magnitude more. Suppose that an
observer, an outfit as a source of disturbances, is within a radius of up to 23
meters from the SR. In this case, a powerful or weak, periodic or non-periodic
signal, the interference will be superimposed on a periodic signal from the PO.
In this case, obviously the spectra of signals of interference and MO will be
overlapped, given that the ground is characterized by low-frequency seismic
filtration. The signal from the same MO changes its spectrum, which is recorded
by the SR when changing the distance to the MO. Consequently, in essence, at
the time of mixing the signal from the obstacle placed near the SR and from the
MO, the efficiency of applying such signs of distinguishing the useful signal
as its frequency, spectral difference is lost. Consequently, a new task arises in
the search for an effective signal distinguishing the signal from the PO placed
in the near-range detection zone of the three-coordinate SR of the signaling
device for the protection of the amplitude of the signals. The solution of this
problem is seen using a three-coordinate SR, which in the literature is still
called vector-phase joint venture, three-component SR, trifon.

as an indicator of information security breach. An ensemble of models has been
obtained that makes it possible to detect both typical manifestations of
abnormal network activity and new elements of network anomalies. The models
included in the ensemble have the ability of self-tuning, in this connection,
they can easily adapt to changes in the observed processes.

Monitoring

Authors:
Han Gye, Heo Go, Hong Gok
Abstract:
In this article we consider
the information technology of monitoring, decision-making support and
identification of the student’s health, by which one can characterize the state
of students in terms of determining well-being. The structure of the concept of
well-being was defined, which allowed to build a comprehensive student’s
well-being card. The structure of this card is presented and characterized, which
is the main element for developing the structure of the system. The main
components of the student’s comprehensive well-being card are described and
described: physical, mental and social. Each of these components has its own
data set and is intended to store specific information that is intended to
diagnose the relevant field of the student’s activity. The article presents the
structures of these components. In accordance with the tasks, 4 levels of user
were proposed for work with this technology. The structural scheme of the
system, which consists of three levels: the level of the medical worker, the
level of the manager and the level of the student, on each of which there are
software tools that are designed to work with the relevant subject area, are presented.
Each functional program works with its own database. Between different modules
are organized parallel and contract links. Distribution of the functional
purpose of various structural modules necessitates the construction of a
methodology for the operation of information technology, which will reflect the
step-by-step sequence of data placement in the database. Thus, the article
proposes the architecture of information technology for the identification of
students’ health, which corresponds to the multi-level structure of health
care, provides a complete form of organization of information exchange and
provides an opportunity to integrate it into the structure of a single
technological process, united by a single information flow.

Abstract:
The method of determining the
coefficients of the Kalman filter, in the processing of low-intensity
electronegative retentions, in quantum (“photon”)
electro-retinography, is improved for the task of detecting the risks of
neurotoxication (detection of neurotoxicants, evaluation of their type, quantitative
characteristics, exposure time, etc.), by using the method of screening in
several iterations, with a step change. On the basis of the determined
coefficients, a Kalman filter was synthesized for the processing of a
low-intensity quantum electrolyte signal. Comparison time of the algorithm
determining factors addressed by direct enumeration, and improved search
algorithm with variable step-busting. The low-intensity quantum
electretinosignal, based on the standard electric retino-signal, is simulated.
The processing of the simulated quantum electro-reticulum has been improved by
the improved method of determining the coefficients, which led to a reduction
in the search time of the coefficients by 120 times, and a reduction in the
computational complexity of the search algorithm. The algorithm for determining
the coefficients through direct directed selection is realized in the software
environment of Matlab.

Progressing of Pathologies of Retina
Authors:
Sophie Bos, Sem Berkenbosch, Lucas Berg
Abstract:Abstract:
Idiopathic macular
degradation (IMD) is one of the most common lesions of the central region of
the retina, which involves a retinal defect in the field of yellow spot that
occurs in elderly patients. The main instrument that registers and performs the
analysis of these pathologies is an optical coherent tomography (OCT). For a
detailed assessment of eye condition, it was suggested to evaluate a number of
indicators during diagnosis. The main criteria of the differences in one stage
of the pathology from the other, which allow the detailed examination of the
macular region of the retina of the eye, are as follows: the presence of
swelling in the macular zone, the diameter of the defect formed, as a result of
progression of the IMD, the thickness of the retina in the zone of phoevole,
the thickness of the retina in the zone of phoevas, the state of the central
vision, the presence of detachment of the vitreous body. In order to make a
decision in the conditions of incomplete information about the condition of the
retina of the eye, a model was created that “describes” the course of
the doctor’s thoughts when diagnosis is made. To this end, it was proposed to
develop and implement a block of tuning membership functions, using fuzzy
logic, including fuzzy sets. According to the results of theoretical and
practical research, a system and method of analysis of the macular area of the
retina of the eye have been developed, the application of which on the basis of
the fuzzy logic device increases the efficiency of complex diagnostics of the
retina of the eye.

Abstract:Abstract:
The paper deals with the

geometry of the six infinitely close positions of the mechanism, which consist
of the use of six-point interpolation nodes (Burmester points of the 5th
order), mathematically provide the highest order of touching the connecting
curve of the pivot quadrilateral mechanism to the circular arc at that point.
An analytical-numerical method for the determination of such points is given.
It is established that there are cases when there is only one point of the
Burmester 5th order in the connecting plane, which can be used for the
synthesis of mechanisms.

Speech
Bank Compression for High Quality Concatenated Synthesis Systems
Authors:
Molly Perez, Bethany Thompson , Harry Roberts
Abstract:
Text-to-speech conversion
systems based on the concatenated synthesis technique with unit selection are
able to produce synthetic speech of very good quality, with intelligibility and
naturalness close to human speech. To accomplish this, it is necessary to use
speech banks containing examples of various phonetic and prosodic contexts.
Frequently, banks used in very good quality synthesizers last for tens of
hours, making their memory occupancy very high. In addition to the recording
banks, concatenated synthesis systems use a set of information to calculate
costs in the process of selecting units, contributing to the memory occupation.
The present work presents techniques to reduce the memory occupation of
concatenated speech synthesis systems. The recording bank of the system under
consideration is compressed using the iLBC codec, which provides the random
access capability to the encoded data, fundamental for applications in
concatenated speech synthesis. The parameter bank, in turn, is compressed using
vector quantization of the spectral coefficients in the unit selection process.
The proposed techniques allow reducing the memory occupancy of the considered
system by up to 79%, without great losses in the quality of the synthetic
speech.

Authors:
Julien Déricourt, Maxime Bignon, Alexandre Bilodeau
Abstract:
This work proposes a new
technique of pitch contour conversion for application in voice conversion
systems. In the proposed approach, the pitch contour is modeled by the
superposition of two components: the macroprosodium and the microprosodium. The
components are estimated using the MOMEL (modeling melody) algorithm and
different conversion strategies are used. The performance of the proposed
method is compared with the two methods most used in the literature: conversion
using Gaussian normalization (GN) and Gaussian mixtures (GMM). The subjective
performance of the methods considered is evaluated through two subjective
tests: preference and similarity. The experimental results confirm the adopted
measure, indicating a preference for the proposed method.

Modification
of the Wavelet Analysis Technique to Detect Anomalies in the Computer Network
Traffic
Authors:
David Vida, Daniel Szöke, Tamás Thuri
Abstract:Abstract:
To ensure reliable data
transmission in the network, it is necessary to use adequate methods of detecting
anomalies, which will enable to detect abnormal network traffic, to estimate
the magnitude and parameters of the anomaly. Statistical methods of analysis
are most common for the implementation of technologies for detecting anomalies.
Quantitative analysis of the network based on the statistical approach is based
on the analysis of data sets in the form of dynamic series – statistical
information on the passage of traffic. The work is devoted to solving the
problems of improving the methodological support of the analysis of traffic of
a computer network using the modified wavelet analysis method, in which the
Fourier series acts as an approximating function, the anomalies are identified
on the basis of the deviations of the idealizing profile from the real and
abrupt changes, the detailed coefficients.

Authors:
Francesco Vezzali, Luca Pastine, Matteo Abate
Abstract:Abstract:
With the development of
information technology, there is a growing need for simulation simulation of
complex systems to seek out optimal control parameters for them. In this
regard, there is an increase in the requirements for simulation tools, in
particular, the task of ensuring high speed construction and modification of
simulation models. Solving this problem is proposed using the Petri-object
modeling technology, which is based on the formalized description of the
dynamics of the Petri network system. The work is devoted to the development of
the intellectual component of visual programming of stochastic networks Petri
software of the Petri-object modeling of discrete-event systems. A mechanism
for preserving models constructed by graphic object manipulation in the form of
Java code software is created, as well as the restoration of visual models from
a program code with automatic arrangement of elements of the Petri network so
as to maximize the ease of perception of models and the speed of their construction.

Bases of Developing Economic-Mathematical Model of Analysis of Business
Processes at Industrial Enterprises
Authors:
Hiroki Yamamoto, Kazu Nakamura, Shun Kobayashi
Abstract:
The article presents modern
approaches to the development of an economic and mathematical model for
analyzing business processes at industrial enterprises. The set of developed
functional models (the IDEFØ method with the description of the process of
IDEF3, which complements it), organizational and information (data flow
diagrams-DFD) models allow a detailed analysis of the enterprise, which is
studied, in terms of its business processes, the relationships between them and
the environment. These models answer the question of how processes in the
enterprise proceed in time and space, but the question remains quantifiable on
the flow of data and materials that arises when the lower levels of
decomposition have been achieved during the simulation process. From a
practical point of view, it is interesting to construct an economic and
mathematical model for analyzing a multichannel mass service system with
limited expectations as the most complex and typical case for modern
productions. At the same time, we believe that all n channels of the system are
equally achievable for all applications. Information about the production
process and its characteristics, obtained as a result of economic and
mathematical modeling, allows the subject specialist to carry out a detailed
analysis of the main properties of the process. As a result of this analysis,
specific recommendations can be developed for improving production equipment,
its efficient use, improving product quality and profitability. Therefore, the
method of economic-mathematical modeling is a powerful tool for researching
operations in the field of production processes. According to the research
results: – development of algorithm for building models, which will determine
their types, sequence of development and interconnection; – development models
of enterprise analysis within the framework of the developed algorithm, which
allow to carry out a detailed analysis of the enterprise in terms of its
processes (to the level of individual technological processes), organizational
structure and information flows (databases); – development of the economic-mathematical
model of the analysis of technological processes and software for
implementation of the developed model..

Developed Approach to a Neuro-Interface Manipulator
Authors:
Daan Baas, Emma Beek, Tess Beenhouwer
Abstract:
Neuro-computer Interface (NCI)
(also called the direct neural interface, brain interface, brain-computer
interface) is a system designed to exchange information between the brain and
an electronic device (for example, a computer). In unidirectional interfaces,
external devices can either receive signals from the brain, or send signals to
it. Bidirectional interfaces allow the brain and external devices to exchange
information in both directions. At the heart of the neuro-computer interface,
the biological feedback method is often used. Any movement, perception, or
inner thinking activity is associated with a specific activation pattern of
neurons that interact with each other through electrical impulses. These
currents create an electromagnetic field that can be registered outside the head
using electroencephalography (EEG) and magneto-encephalography (MEG) methods. The
system of constructing a neural interfacial manipulator for the management of
technical devices (including computer equipment) for people with disabilities
is considered. The device being developed can find application in any control
systems for various objects.

Andros Karaulin, Bogdana Kapitsa, Asja Zharkov
Abstract:Abstract:
During making of the surfaces
of the teeth of the gears, the gap between the teeth may reach the values in
which the contact interaction between the teeth becomes shocking. It was found
that during the growth of the gap, the deformation of the surfaces of the teeth
during shock interaction may increase several times compared with static
deformation. When solving dynamic tasks, initially solve the static problem of
contact interaction between elements of conjugation, since the elastic and
deformable characteristics of the material of the conjugate elements do not
depend on the conditions of their interaction. The problem of compression of a
cylinder in diameter from two sides is considered. Local elastic deformations
in this case can be taken by equal contact between two cylinders of the same
radius and the material under the action of compressive forces. The method of
calculation of the maximum allowable gap in conjugation of the teeth of the
toothed clutch is given in the work. Keywords: maximum permissible clearance, gears,
contacts interaction of gears. The paper presents a method for calculating the
maximum permissible gap in the conjugation of the toothed gear teeth.

System

Authors:
Adéla Grzyb, Klara Hašek, Karolína Janáček
Abstract:Abstract:
In accordance with the
accepted classification, the blast furnace belongs to the category of unique
technical objects possessing a complex multi-element structure. Closeness of
the process, high temperatures, the lack of adequate mathematical models and the
need for constant monitoring of the current state of the domain process,
forcing technologists to use indirect methods of diagnosis. A consequence of
this is the provision of blast furnaces with a whole complex of metrological
equipment. The received data are transmitted to the control panel in the form
of graphs of changes in the values of the monitored parameters and signaling
of critical zones. Based on this information, the technologist in real time
should assess the state of the technological process and decide on the method
of management. The ability of a person to adequately perceive and evaluate
information is very limited, therefore, the development of methods for
automatic processing and visualization of information received from sensors is
an urgent task. The synthesis of a system with parametric invariance of the
output for controlling the growth of a single crystal has been carried out. It
is shown that the synthesized control system is able to suppress disturbances
characteristic of growth systems.

Artificial Extension for Speeches in Telephony Using Phonetic Classification
Authors:
Ritsa Chloros, Tatiana Dimitropoulos , Nitsa Michalidis
Abstract:
This work presents a new
strategy to implement artificial bandwidth extension (ABWE) systems for speech
signals applied to the public switched telephone network (PSTN). Specifically,
here is proposed a strategy based on phonetic classification aiming to satisfactorily
represent segments of speech with energy concentrated at high frequencies,
surpassing results presented in the literature. To this end, attribute
selection techniques applied to limited band speech signals are investigated,
improving the classification in broad group phonetic (BGP) with emphasis on the
discrimination of phonemes belonging to the fricative phonetic group.
Additionally, this work is also discussed the integration of the ABWE system
proposed in automatic speeech recognition (ASR) systems applied to the PSTN. In
particular, aiming at enhancing ASR in PSTN, the steps of speech signal
attribute extraction as well as the stage of construction of the acoustic model
are developed based on synthetic broadband (WB) signals estimated from the
enhancement of narrowband (NB) signals using ABWE. The results obtained
highlight the subjective quality of the reconstructed speech signals and gain
in the performance of the RSA, confirming the effectiveness of the strategies
proposed in this research.

of the Effect of the Source Radiation Spectrum Width on the Sensitivity of

Authors:
Dora Vince, Laura Baán, Dóri Török
Abstract:
As light sources,
light-emitting diodes are chosen whose emission spectra correspond to the
absorption spectrum of CO, but differ in spectral width by (4 ÷ 5) times. It
has been found that narrowing of the emission spectrum leads to an increase in
the sensitivity of the optical part of the measuring channel, but the degree of
narrowing of the spectrum affects the linearity of the change in the
information parameter from the change in concentration; The best result is
observed when the absorption spectrum of the gas component and the emission
spectrum of the light-emitting diode match. Ways to increase the optical power
of radiation sources are proposed to increase the signal-to-noise ratio while
maintaining the effect of increasing sensitivity, based on the modernization of
the optical part of the measuring channels.

records them in memory and, if necessary, reproduces. To the inertial trackers
on the very front can be attributed glasses of virtual reality. However, the VR
glasses work only with the mobile display of the mobile device and cannot be
used when you need to control the mouse when the hands are occupied when a
person typing the text in both hands on the keyboard and distracting only in
the case of verification, at such a moment it is sometimes necessary to stretch
to the mouse to set the cursor in a certain place, the more they cannot be used
by people with disabilities. We propose a developed inertial tracker can be
used to work with the computer both at home and in the production, the gaming
industry, and for people with disabilities who cannot use their hands.

Abstract:
An approach to the
development of a mathematical model for the formation of a defect layer in the
process of diamond grinding of parts from the ceramic is proposed. During the
experimental modeling of the contact of diamond grains with the surface being treated,
it is established that with an increase in the dynamic impact on it, the
intensity of defect formation increases, which will adversely affect the

Authors:
David Nelson, Josh White, Jake Carter
Abstract:
A significant reserve for
increasing the milling performance of closed and semi-closed profile (T-shaped,
swallow tail type, etc.), as well as other slotted slotted grooves, is the
elimination of the limitation on the presence of unharmed chips in the processing
zone. An effective remedy for this restriction is the forced removal of chips
by means of devices using the hydrodynamic potential of pressure jets of a
liquid, a water-air mixture, etc. At the same time, the theoretical foundations
of the creation of such devices are not established. Theoretical studies of the
chip removal process for milling of closed profile grooves were performed. A
technique for conducting experimental studies of the chip removal process has
been developed. Experimental studies of the chip removal process have been
carried out.

Analytical
Determination of the Minimum Power Plant at the Succession
Authors:
Camille Ampère, Léa André, Manon Angelle
Abstract:
When machining the axial
tool, the most characteristic deviation from the cylindrical is the cutting of
openings. The presence of cutting openings greatly affects the operational
properties of the site or machine as a whole. The contact surfaces of machine
parts occur at the vertices of the microstructure of the most protruding
surfaces of contacting surfaces. This kind of contact leads to intense wear, as
well as increases the gap between the surfaces. The cause of the formation of
hole fissures is forced oscillations of unbalanced radial force. In this case,
the value of unbalanced radial forces varies according to the periodic law. The
article deals with the problem of analytical determination of the force of the
tool under pressure by the spring of the floating cartridge during the
operation of the control. The use of floating cartridges can significantly
reduce the size of the cut of the treated holes.

Abstract:
The improved mathematical
model of the grinding process allows not only to fully utilize the cutting
power of the working surface of the circle due to the consideration of the
unsteadiness of the process, but also reduces the complexity of the search for
optimal regimes due to: use of generalized grinding regimes the use of
analytical calculations of technical limitations on a technical limitation, the
need for only one experiment to determine the change and current limited
cutting power of the circle. The method of finding optimal processing modes is
considered, which, due to the use of the advanced mathematical model of the
grinding process, taking into account its non-stationary nature, provides an
increase in the productivity of grinding and a reduction in the complexity of
the search of optimal processing modes.

Abstract:
Telecommunication systems are

telecommunications equipment can be damaged, which leads to undesirable
information loss. The process of diagnosing the critical states of a telecommunication

Abstract:
Increasing the reliability of

technical, organizational and economic aspects. In the organization of such
events, the leading role belongs to technical diagnostics, which allows to determine
the state of equipment directly in the process of operation, as well as to
predict its changes. The use of diagnostic tools provides an economic effect
only by reducing the cost of maintenance and repair by 20-25%, due to the
transition to maintenance by actual state, and not by regulations. The
mathematical models of the predictors of the acoustic emission signals at the
level of atomic interactions are presented, which allow obtaining equations of

Processing Techniques for Changing Prosodic Parameters Applied to a
Text-to-Speech Conversion System for the Spoken Language.
Authors:
Maria Hansen, Julie Johansen, Emma Olsen
Abstract:
Text-to-speech conversion
systems aim to transform a text with unrestricted vocabulary into a spoken
message. This process consists of two basic steps. In the first, linguistic
processing techniques perform the extraction of a symbolic representation of the
acoustic parameters from the input text. The symbolic representation is
transformed into a speech signal through signal processing techniques. One of
the methods of speech synthesis is the concatenation of previously recorded
speech segments. The present work presents the development of a technique based
on LPC analysis / resynthesis with residual excitation to alter prosodic
parameters. The objective is to apply it to a text-to-speech conversion system
based on concatenated synthesis for the Spoken language. In this technique,
simple copying and cutting operations are performed on the residue signal,
allowing the pitch to be changed. Changing the duration is done by deleting or
copying entire frames of analysis. This technique presents a reduced computational
load, allowing the implementation in real time. Objective analyzes and
preliminary perceptual tests showed a good performance of the technique.

Abstract:
In this work we present an
objective evaluation of an important class of distortion measures used in voice
coders, in the vector quantization stage of the LPC filter parameters. These
measures are based on the weighting of the quadratic error, when the parameters
of the LPC filter are the LSFs. The evaluation considers computational
complexity and performance in terms of spectral distortion. A comparison of the
efficiency of distortion measurements is presented, using as reference of
quality the spectral distortion (SD). The results indicate that the measurement
of POWER is rarely the best option for the quantification of LSFs. The measures
of the quadratic error and the DIFFERENCE led to performances superior to that
of the quantizer using the measure of the POWER.

compensating the software and hardware of the temperature drift of an optical
meter is proposed, in which the LED is used as a temperature-sensitive element
for the hardware compensation, and for the software it is a temperature sensor.
The hardware and software implementation of the developed method has allowed to
increase its accuracy: the value of the further error of measuring the methane
due to temperature changes was no more than %, which is 4,5 times less than the required value
according to the technical specification for the development of the meter (no
more than %). In this case, in the methane concentration range
of 0 to %, the fundamental absolute error should not exceed %, and the additional error is two times the value of
the fundamental measurement error.

Abstract:Abstract:
The article analyzes the
approaches to the simulation of computer systems (KS) on the basis of
programmable logic integrated circuits (FPGAs). Found that the basic models are
abstract and low-level. The tasks, advantages and disadvantages of each of them
are singled out. It is concluded that the use of low-level models in most cases
is more justified. However, the low speed of their work creates the
preconditions for the development of two models, each of which is used for the
appropriate range of tasks. Recommendation on the use of models is developed.
The problem of debugging nodes and blocks based on the low-level simulation of
FPGA-based computer systems is specified, namely: 1) using the system model as
a test shell when debugging each device; 2) simulation of emergency situations
detected when testing real devices; 3) creating stream tests to detect errors
when interacting with devices; 4) collection of statistics for the evaluation
of arbitration algorithms and data flow management; 5) assessment of system
performance. An analysis of each sub-task has been carried out on the purpose,

Abstract:
The paper is dedicated to the
analysis of the effect of the fluid flow rate on the output signal of a
vibrational frequency density meter – the frequency of auto-oscillations of a
tubular resonator close to its own. To this end, a differential equation is
constructed and solved, describing the intrinsic transverse vibrations of the
tube along which the flow of the liquid is organized. From the obtained
relation connecting the frequency of natural oscillations of a tube with its
geometric dimensions and mechanical parameters, density and velocity of fluid
flow; it follows that with increasing frequency, the resonator frequency
decreases. The article provides a condition, the implementation of which makes
it possible to synthesize in practice the design of vibration-frequency density
sensors, the indications of which depend little on the change in the flow
velocity of the liquid being measured. One of these synthesized densitometer
designs are considered, using a two-cavity sensor.

Abstract:
The work is devoted to
research in the field of improving optical data transmission systems. The
effect of material dispersion on the shape of the optical signal is
investigated. The work assumes limitations: it is believed that the
transmission is carried out in a single-mode fiber with circular polarization;
the signal power is assumed to be sufficiently small. Nonlinear effects are not
taken into account. The signal is considered narrow-band. Under these
conditions, the problem of synthesizing signals possessing optimal dispersion
properties is posed. The dispersion of the signal in the form of a functional
that depends on the spectral density of the signal is introduced. The
optimization issue is expressed as a variation issue with restrictions as
inequalities. Limitations take into account the possibilities of physical
realization of signals. A numerical-analytical approach for solving the
optimization issue is presented. The solution algorithm is based on orthogonal
function systems.

Calculation
of Characteristics of the Self-Simulated Traffic, Approximated by Webbull
Distribution
Authors:
Oxun Fazul
Abstract:Abstract:
The methods of increasing the
accuracy of calculating the quality of service characteristics in a network
with self-similar traffic are investigated due to a more accurate determination
of the Hurst coefficient depending on the parameter of the Weibull distribution
form. Since self-similar traffic (the time interval between applications) is
best described by the Weibull distribution, it is for him that a new formula
for calculating the coefficient of self-similarity of traffic is obtained. In
this case, the calculation of the quality of service characteristics can be
performed on the basis of the Norros formula, which is valid for the model fBM
/ D / 1 / .

Generation of Random Removals for Different Types of Source of Light
Authors:
Deus Samer, Danish Kendi
Abstract:Abstract:
One of the main characteristics of a light instrument is the curve of light intensity. There are many methods for calculating the light intensity curve, and one of the most modern ones used in most automated calculation programs is the Monte Carlo method. The Monte Carlo statistical method is based on the direct mathematical modeling of the research object, which consists in simulating the propagation of rays from the light source, reflection from the reflecting surface and fixing on the calculated plane. The paper considers three main types of light sources: bullet, disk, and cylinder. Formulas for a random beam were derived for a ball source and a disk type. For a cylindrical source, a random beam formula already exists. Also, the influence of the form of the light source on the model of the random beam coming from the source was investigated. The results obtained in the future can be used to generate a random beam, to simulate reflection from the reflecting surface and to the light intensity of the light instrument.

Invariance
of the Symmetry of Optical Pulses
Authors:
Kaylen Nan, Kostia Stognobich
Abstract:
The work is devoted to the
research of analytical properties of mathematical models of optical pulses. A
special case of the influence of material dispersion on the shape of the
optical pulse is considered. It is proved that, when a number of conditions are
satisfied, the symmetry property of the optical pulse proves to be invariant to
the material dispersion in the optical fiber. To prove the stability of the
symmetry of an optical pulse, the properties of even and odd functions are
considered. These functions are combined into a common class of functions with
an even square. The properties of integral transformations with preservation of
symmetry are considered. It is shown that the Fourier transform belongs to this
class of integral transformations. The invariance of the symmetry of the
optical pulse is shown both for the case of second-order dispersion and for
higher-order dispersion. Accordingly, it is justified that the energy
distribution in the spectral region will also be a symmetric function with
respect to the carrier frequency in the case when a symmetric pulse is
introduced into the optical fiber.

Abstract:
Considering the main
components as a vector defining the direction and magnitude of the
“motion” of the dynamic system, one can find the difference between
the directions of motion of the model systems (state of the organism,
characteristic for specific diseases), and the specific patient in the form of
a generalized characteristic – the angle of the total deviation of eigenvectors
of diseases and the patient. The minimum deviation angle will indicate the most
likely diagnosis. Having arranged the increasing magnitude of the angles
between the patient’s vector and disease vectors, one can obtain information
about diagnosis that is similar in probability. This work is devoted to solving
the problem of medical diagnostics from the position of factor analysis on the
basis of a patient’s review, processing of the results of analyzes and
identifying factors that affect the patient’s condition.

Abstract:
Flying saws for medium-grade

energy load of the electric drive of the carrier body (platform) of the flying
saw is in the mode of dispersal from a stationary state, which ends with
spatially-fast synchronization of the cutting tool with a cutting section on a
moving profile. In this connection, the task of energy-efficient control of the
electric drive of the carrier body in the mode of overclocking –

Selection
of Attributes and Phonetic Classification of Speeches of Limited Band
Authors:
Andriana Sumenkova, Namuli Can
Abstract:
This paper presents a
strategy for attribute selection applied to the phonetic classification of
limited band speech signals. In particular, the proposed strategy aims to
improve the phonetic classification in broad group phonetic (BGP) with emphasis
on the discrimination of phonemes belonging to the fricative phonetic group.
Specifically, the characteristic attributes of speech signals are investigated
through methods based on machine learning and component analysis, such as
mutual information (MI) and correlation-based feature selection (CFS). In this
context, several state-of-the-art algorithms are investigated, resulting in a
strategy of identifying the optimal attributes of the limited-band speech
signal that facilitates the distinction between different BGPs. The results of
simulations allow to infer about the selection of the best attributes to be
considered in the composition of phonetic classifiers, proving the
effectiveness of the proposed strategy.

Automatic
Generation of Variants of Lexicals for Speech Recognition Systems
Authors:
Yash Mehmet, Ahmet Taib
Abstract:
In this work, we propose a
strategy for automatic generation of lexical pronunciation variants of a speech
recognition system, independent of speaker. The described variations refer to
phonological processes proper to natural languages, such as insertion or deletion
of segments, segmental assimilation and syllabic structuring. Intra- and
inter-word variations were considered. We compared the number and types of
variants presented in the transcripts obtained automatically with those
performed by an expert linguist and verified that the agreement between them
was very close to 100%.

Restoration
of Images Via Kalman Filtering and Considerations on Quality Evaluation of
Restored Images
Authors:
Maya Rozite, Ramon Pchelka
Abstract:
This article deals with the
use of evolutionary programming (PE) in image restoration systems via Kalman filtering
and the proposal of a measurement for quality evaluation of restored images
based on human visual perception. PE is used in the parametric estimation step
of the reduced order model Kalman filter (ROMKF). As a consequence of the
parametric estimation control function, it presents excellent locations and the
use of optimization algorithms sensitive to the initial conditions, the
traditional strategies restart the restoration process several times, with
different initial conditions, in an attempt to overcome the problems of
undesirable convergence. However, the simulations presented show that the
restart strategy is inefficient and, on the other hand, a single restoration
via ROMKF-PE is sufficient to obtain an image that is representative of the best
that the restoration system can offer. This thesis also proposes a measure to
evaluate the quality of restored images, called composite quality measurement
(MQC), which is based on human visual perception. In the development of MQC,
experiments are performed that evaluate the correlation between human
perception of quality in images and objective measurements of the effects of
frequency distortion and noise injection, considered in isolation. The MQC is
based on the noise quality measure (NQM) and the frequency distortion quality
measurement (MQD), being validated experimentally.

the synthesis with the complete unit bank, with no impairment to the
intelligibility and / or naturalness of the synthesized speech.

Perspectives
of the Use of Blocking Technology in the Network of the Internet River
Authors:
Sharip Denis, Oriane Sagadi
Abstract:
Internet of Things (IoT) is
the next stage in the evolution of the Internet on the way to a comprehensive
Internet (Internet of Everything, IoE). IoT includes a wide range of things,
such as sensors, actuators and services deployed by various organizations and
individuals to support a variety of applications. The term “Internet of
Things” (IoT) was first introduced by Kevin Ashton in 1999 to describe a
system in which physical objects are connected with sensors and the Internet.
The emergence of IoT has become possible thanks to the development of
microcontrollers and network technologies that allow you to connect billions of
different devices at no cost and effort to create applications that are not
platform-dependent. According to Gartner, in 2020, the world will have 20.8 billion
connected devices IoT. This article examines the state and perspectives of
using blockade technology in the Internet of things. The potential advantages
are highlighted and the problems that need to be solved for effective use of
this technology in the Internet environment are highlighted.

Forecasting
Visit of Supermarkets by Regressional Analysis
Authors:
Finaev Sabadini
Abstract:
Based on the analysis of the
methods based on the functioning of such modern means of forecasting as
Regression Analysis and Forecasting, GeneXproTools and “1C Management by
our firm”, the method of forecasting visits to supermarkets was proposed
using regression analysis, which allows to effectively predict the date of
visit and cost of the client on the basis of previous statistics The inputs
include the amount of customer spend, customer ID, and the date of the visit.
In the process of forecasting, the coefficient of “freshness” of data
is introduced, which determines their influence on the final result of
forecasting. Parameters, the arithmetic mean of which is less important than
the measure of the importance of any of the parameters, are eliminated during
the forecasting process. This approach provides high accuracy, since it only
takes into account the actual statistics of each visitor. High speed is due to
the relative simplicity of the linear regression algorithm, as well as the
optimization of the input data depending on their “freshness”.
Testing on the basis of real statistics of visits to the supermarket showed an
increase of accuracy of 8-10% compared with the program analogue.

Successful
Protection Method of Unemployment Level
Authors:
Mian Mehmet, Olez Qasim
Abstract:
The method of forecasting the
unemployment rate with the use of fuzzy regression analysis is proposed, which
allows forecasting the unemployment rate on the basis of the previous
statistics. The inputs include social and economic indicators such as
unemployment, gross domestic product, inflation rate, household income and
living wage. The idea behind the fuzzy regression model is to use an existing
sample of the identified socio-economic indicators to determine the parameters
of membership functions that best fit the corresponding fuzzy output system.
The variables of a fuzzy regression model for determining the level of
unemployment are fuzzy numbers that are in the corresponding calculated
intervals, with known upper and lower bounds, taking into account the error at
each α-level. This approach to forecasting unemployment, based on the fuzzy
regression method, provides high precision and allows you to perform a forecast
at different levels, taking into account possible variations. Studies have been
conducted to predict the unemployment rate based on such socio-economic indicators
as the unemployment rate in the previous period, the gross domestic product,
inflation rate, subsistence minimum and income of the population using the
developed method, as well as taking into account the real values of the
unemployment rate, have shown an increase in the accuracy of the forecast by 4
, 1 percent for the first year of the forecast, 7.2 percent for the second year
and 10 percent for the third year.

A
New Developed Asynchronous Electric Drive with DC Drive
Authors:
Tereza Evanova, Anglinka Ezotova
Abstract:
Linear asynchronous
adjustable electric drive with the ability to measure the electromagnetic
moment is made in the form of a laboratory stand consisting of a constant link,
an IGBT inverter, an optical drive unit, a microprocessor control unit, Hall
current sensors, and a power supply. In the proposed technical solution, the
resultant rotating magnetic field of the stator and the rotor with a constant
amplitude and configuration at a given frequency of the converter is formed. In
this case, the electromagnetic torque is maximal and depends linearly only on
the relative velocity of motion of the resulting field of the machine and the
rotor within the limits of the double nominal load and, accordingly, of the
double slip. To measure the electromagnetic moment, a booth consisting of dual
motors of constant and alternating current, a friction drum brake and a brake
equipped with a dynamometer, as well as a digital motor rotor speed meter was
made. The results of the experiment confirmed the complete analogy of the
developed asynchronous electric drive with DC drive.

Abstract:
This paper presents a new
strategy for the implementation of automatic speech recognition (ASR) systems
applied to the public switched telephone network (PSTN). The state of the art
reports that ASR systems that decode narrowband (NB) signals perform poorly on
systems that operate with wideband (WB) signals. In order to improve the ASR
systems applied to the PSTN, the stages of speech signal attribute extraction,
as well as the stage of construction of the acoustic model (MA), are developed
based on synthetic WB signals estimated from the signal enhancement of NB,
using artificial bandwidth extension (ABWE). Recognition error rate results are
evaluated and prove the effectiveness of the proposed strategy.

Detection
and Treatment of Natural Clicks in Speech Banks Aiming for High Quality Concatenating
Synthesis
Authors:
Kristy Panchenko, Mariana Dilay
Abstract:
The present work studies
certain degradations produced involuntarily by the human vocal apparatus
itself. Such degradations are here called natural clicks or involuntary clicks.
Natural clicks manifest themselves in the form of low intensity cracks. These cracks
can greatly impair the quality of the synthetic speech produced by concatenated
synthesis systems, especially when such cracking is associated with
discontinuities resulting from the concatenation process. The present work aims
to improve the quality of the speech bank and, consequently, the quality of the
synthetic speech. To this end, techniques aimed at the attenuation and / or
suppression of the natural clicks present in a speech bank are addressed.
Reducing the audible effects of clicks is achieved by considering two stages of
processing: detection and treatment itself. Detection techniques based on
fourth order derived inverse flatting, human hearing system modeling, wavelet
decomposition and artificial neural networks are analyzed here. Processing
techniques based on extrapolation, masking, smoothing and pruning are also
studied. The evaluation of both detection and treatment techniques is done by
reference to a 45-minute speech bank, recorded in an appropriate studio by a
professional broadcaster. Perceptual tests based on listening are performed
aiming to evaluate the techniques studied. Test results indicate a significant
improvement in recorded speech quality. The work developed here applies not
only to speech banks aimed at synthesis systems, but can also be considered to
treat any recorded speech.

Abstract:
This article proposes an
algorithm for smoothing of involuntary clicks and the detection, produced by
the vocal tract, which reduces the speech quality. The proposed method aims to
improve the existing speech banks in the concatenation systems. The proposed
technique for detecting clicks considers bandpass filtering in the low-energy
frequency sub-bands in a speech segment, auto-regressive modeling, prediction
error, and comparison with an appropriate threshold. Smoothing, in turn,
performs a weighting of the segment where the click is detected through a
window function in order to reduce the perception of said click.
