The Multi-model Data Processing Algorithms of the Mobile Radar System 38_1.pdf

The creation features of trajectory processing algorithms for mobile multi-position radars and the software complex for 3D-simulation of a situation, radar surveillance and data exchange (virtual polygon) processes are considered. The combining data and the trajectory processing are carried out based on multi-model procedures of a simultaneous distinction and evaluation of dynamic vector parameters.To examine and debug algorithms, designed for the trajectory processing, a software virtual polygon is developed, which provides a virtual 3D-polygon modeling, including local objects and maneuvering targets, as well as the processes of information acquisition and processing with a given number of mobile radars of various types. The documented materials of all the major processing stages of the observation results of two ‘Reka’ type radars are presented explanatorily. In addition, three models of the objects motion with different dynamic properties are simulated. The developed methods, algorithms, and software can be taken as a basis for the creation of advanced systems designed for the processing of a large number of interacting mobile multi-position radars.

Planning Time Estimation in a Hierarchical Control System 38_3.pdf

Performances of planning efficiency in a hierarchical control system are established. They include the total time distribution laws of plan development in the system from top hierarchical level to separate objects or their collections at all levels. Analytical dependencies of the laws of distribution of total time of development in the system from the laws of planning time distribu-tion on all objects are obtained in general terms. Solutions for standard distribution with known central tendency and mean square deviations are shown. A simulation model designed to compute the approximate laws of total planning time distribution in the system for various number of objects of all levels is proposed. Experimental results are presented for the system with a set structure and operational efficiency of objects. The plotted analytical and algorithmic dependencies allow to estimate the planning time in the hierarchical control system at the development stage with great precision. Algorithmic dependencies as a simulation model are useful at any laws of planning time distribution on objects. Analytical dependencies are accessible at the distribution laws, which are tolerant to the random values toting. Based on the dependencies ob-tained, it would be possible to create and solve a formalized design problem with optimization of operational efficiency performances at limits for the system cost.

Control Synthesis for Double-link Manipulator 38_4.pdf

A stabilization problem of a doubl-link manipulator program motion on a fixed base is solved in this paper. Totally rigid manipulator links are interconnected by an ideal cylindrical hinge and via the same hinge the first element is fastened to the base. Thus, the manipulator can perform motions in a vertical plane only. The manipulator motions are described by the system of Lagrange equations of the second kind. The problem on synthesis of the motion control of such system involves the construction of the laws of a control moments change that allow the manipulator to carry out the motion given by the program in real conditions of external and internal disturbances, and the inaccuracy of the model itself. A mathematical model of the manipulator controlled motion is constructed in this paper in case of control actions in the form of continuous and discontinuous functions bounded in modulus. By applying Lyapunov’s vector-functions and the comparison systems we justified the implementation of the built control laws in the stabilization task of the spectrum of the manipulator program motions. The novelty of the results includes solving the stabilization problem of the non-stationary and nonlinear formulation, without changing to a linearized model, as well as the ability to stabilize not just one but a whole family of program motions. With the help of Maple’s mathematical package a numerical solution of the received system of differential equations using both continuous and discontinuous control laws is found. The corresponding graphs for the coordinates and velocities of the manipulator links proving the theoretical results are built.

Forecasting Time-series Local Trends in the Big Data Analysis 38_5.pdf

According to the forecasts in the field of IT (IDC) the growth of the stored data volumes obtained from various sources will be doubling every two years until 2020. This tendency will remain stable in the conditions of the data increase generated in the OLTP systems, on social networks and by devices in case of mutual exchange of information during the intensive development of the data warehouse, "cloud computing", "the Internet of things" and "digital production" technologies. All that gives rise to a considerable interest in the Big Data analysis and processing from both business and a scientific community. The technology of analytical OLAP-systems for the analysis of the large data, focused on providing a visualization of the multidimensional data and the formation of interactive reports, is one of the most popular in decision support and Business intelligence systems. A promising technology in the field of analysis in addition to the OLAP-systems and aiming at identifying hidden patterns in the large data, is a technology of time series data mining. The most important tasks of time series data mining certainly should include forecasting time series points. A scientific basis of the methodology of the local trends forecasting as fuzzy trends for univariate time series (numeric and non-numeric) which lead to the fuzzy time series are discussed in this article. The solution to this problem is interesting both in theoretical and practical aspects. It is known that fuzzy time series models are proven themselves for a short length time series, and for a long length time series a large computation is required. This paper proposes a k-trend algorithm for extracting local trends out of the big data, considered as a time series, and a time series model in terms of fuzzy local trends is shown. An effect of applying the proposed approach, expressed in a significant reduction of the computational cost when using a fuzzy time series model is shown.

The Algorithm for the Frequency-dependent Thermal Impedance Parameter Identification of Thermal Circuits of the Semiconductor Devices 38_6.pdf

The limit functionality and reliability of semiconductor devices (SD) are determined by the active region temperature of the device structures when the SD is operating as a part of electronic equipment. For practical applications, this temperature is calculated in accordance with the principle of thermoelectric analogy based on the equivalent thermal circuit which is presented as an electric circuit of several series-connected RC-elements, each of which corresponds to a specific layer of the SD-structure. The effectiveness of the SD-assembly quality control and the reject of devices with heat sink defects depend on the accuracy of determining the parameters of their equivalent thermal circuit. A brief analysis of the known methods for identifying and determining the parameters of the SD equivalent thermal circuit over the transient thermal characteristics is presented. A more accurate algorithm for the identification and the calculation of the parameters of equivalent thermal circuits in the form of SD multilink RC circuit for the frequency dependence of the modulus and the phase of the thermal impedance is proposed. The algorithm approbation is performed in terms of the identification and the calculation of the parameters of the thermal model of a low-power hetero junction LED of the Vishay production TLCR5800 type. The possibilities of automation of the proposed algorithm in terms of mass control are considered.

Mathematical Modeling and Numerical Analysis of a Thermal State of Turbo-mashine Blades Affected By a Supersonic Dispersed Flow 38_7.pdf

The development of the advanced gas-turbines must ensure their operation under the conditions of an increasing temperature of a working body to improve the efficiency during in a reliable and efficient operation. In this paper, a mathematical model and a method of a numerical research of a thermal state of turbo-machine blades affected by a supersonic dispersed flow including a gas-dynamic temperature stratification phenomenon are introduced. The adequacy of a turbulent dispersed boundary layer model was verified by comparing the calculation of the heat transfer coefficients of the dispersed flow in the nozzles with the experimental data. In order to improve the accuracy of the calculated prediction of the thermal state of the blades due to obtaining the reliable data, as well as the efficiency of cooling systems for the increasing resource of the blades, a software and information complex integrated into the Solid Works package is currently being developed on the base of the Turbo Works package at the Department of Heat Power Engineering of Ulyanovsk State Technical University. The research results of the temperature stratification will be included into this software and information complex as a unique information base. As the analysis of the numerical study results shows, the application of the developed convective-film cooling temperature provides the temperature reduction to the trailing edge of the turbo machine blade by 1.6 times compared with the convection cooling.

Solution to the Problem of Runtime Diagnostics of Ionospheric Radio Links 38_9.pdf

The contributors has developed the algorithms and implemented the specialized software designed for on-line data processing of ionoshperic sounding by chirp signals, which includes algorithms designed for automatic scan and the computation of key characteristics of arbitrary frequency radio channels based on the separation of signal-to-noise time series and the subsequent estimation of their statistical parameters. This software tools can be used for the automation of control process of frequency resources of ionospheric radio links. The experimental validation of efficiency of the frequency-domain signal extraction algorithm during automatic processing of the experimental radiosonde data obtained at different times of day and on different radio links was also completed. The results of this validation demonstrate the effectiveness of the procedure proposed. A feature of this software is to obtain estimates of radio channel parameters on the basis of the signal processing in the time domain, rather than in the frequency domain and to use methods of detection of abnormal samples in experimental measurements when extracting analyzable signals.

Ontological Retrieval of Technical Documents on the Basis of an Intelligent Agent Model 38_11.pdf

An intelligent agents modeling for the formation of information requests to an electronic archive of technical documents is considered in this paper. The intelligent agent contains an ontological description of the designer profile, which is expressed as a fragment of the domain ontology. In fact, the intelligent agent has information about the preferences of the electronic archive user. This information has a conceptual representation and it dynamically changes depending on the changing needs of the user. The designer profile is periodically updated with the concepts of the subject area from Wikipedia, so the applied ontology is expanding automatically. Basing on the user’s profile the intelligent agent solves the problem of the information retrieval of technical documents more effectively. The information retrieval algorithm is based on an ontological model which considers the user's query and a technical document as a set of concepts. The objectives of the intelligent agent are a replenishment of the information about the user’s needs in the designer profile, a conversion of the user query to a conceptual view and finding of the text documents requested by an electronic archive user. In the research process the subsystems of an ontological searching and an automatic generation of a concept network for the ontology were developed. Computational experiments were performed with these subsystems, which prove the effectiveness of the implemented approaches.

Structural Design of Configured Patterns of Avionics Parts 38_13.pdf

The paper presents a set of means for structural designing the configured patterns of avionics parts. The specificity of the offered approach to designing this kind of an equipment is defined with the use of means of conceptual experimenting. Such type of experimenting suggests a reflection of the life cycle of any pattern to a semantic memory of the question-answer type. The structure and attributes of the semantic memory cells are focused on coding of models of questions and answers from the viewpoint of their use in solving the creative tasks. In such modeling, any conceptual experiment is conducted as automated mental experiment the structure and content of which are operatively used in designing of patterns.Configured patterns as a specialized equipment for manufacturing and checking of avionics parts have a set of features the main of which are the following: complicated geometrical forms, small rigidity, greater scales, strict requirements to accuracy of manufacturing. Moreover, in the creation of each pattern, it should repeat not only the geometrical forms of the corresponding detail, but needed utility forms should be included to the pattern also. Such additional components of the patterns are oriented on conditions of their use, for example, in assembly operations with other parts. Necessity to take into account the diverse points of view on a pattern leads to creative tasks, which had better to solve preliminary (before making a pattern) on models, by experimenting with their decisions. The decisions that are offered in the paper are realized and checked up in the toolkit WIQA (Working In Questions and Answers) the environment of which supports conceptual modeling and conceptual programming. For designing the configured patterns, cartographical modeling of the structure and specifications of patterns, and also pseudo-code programming of their laser processing are included in WIQA functions. Inclusion in the life cycle of designing the patterns the opportunities of experimenting with their conceptual models leads to increasing the automation degree of designing and quality of its results, reducing the technological time of pattern production. The use of experimenting also promotes the prevention of mistakes and detection of mistakes, and it facilitates the porting of numerical control programs to other CNC laser cutting machine tools.

Automated Grouping of Machine Components Such As Rotation Bodies Using Cluster Analysis 38_14.pdf

In a multiproduct batch production the technological basis for the computer numerical control (CNC) machine tools engineering can only be a properly selected group of parts. Therefore, on the basis of the cluster analysis application a methodology is developed which enables to quantify the similarity of the parts based on constructive and technological characteristics and to implement the parts sections. As a objective function (or as a grouping criterion) a following condition is adopted: a maximal usage of at least one CNC machine processing parts of a particular group for a year.In practice, the method is implemented in terms of a regional components data bank, which contains the information about 130 thousand types of parts. The calculations of the distances between clusters are performed on PC by means of a software product ‘STATISTIKA’, which enables to get a result automatically in a form of a dendrogram after the initial data is intro-duced. The dendrogram shows an optimal sequence of all clusters unification. As a result of calculations, nine groups of parts are formed which meet the objective function and which are appropriate to use as a process basis of the design of the range of advanced CNC-lathe machines. The specification requirements for the engineering of the range of advanced CNC-lathe machines are coordinated with the machine-tool enterprises of Moscow, Samara, and Ulyanovsk.
