Effectiveness of Complex Application of Increasing Data Processing Validity Methods 39_1.pdf

An analysis for destructive factors effecting on data processing validity under conditions of complex electromagnetic environment is carried out. It is noted that an electromagnetic pulse (EMP) makes the most hazard effect on computer appliances (CA) functioning. The electromagnetic pulse leads to computer appliances functioning temporary problems, namely to errors or a computer appliance elements physical destruction that is a failure. The fulfillment of requirements for data processing validity under electromagnetic effect is not provided without implementation of increasing validity methods in CA.The article is dedicated to data processing validity researches in case of computer appliances functioning problems caused by an effect of electromagnetic pulse. The methods for the increasing of data processing validity based on information, structure, and temporary redundancy are considered. A procedure for CA data processing validity specification is provided for each of these methods. The paper captures each of these methods benefits and notes that using these methods separately does not provide fulfillment of the requirements to all validity classes that are defined by international standards. To obtain the best possible result, it is necessary to use the combination of all these methods.

Computer appliance, electromagnetic pulse, data processing validity, increasing validity methods’ combination.

Unification of Redundant Code Decoding Algorithms in Integrated Information-management Systems 39_2.pdf

The increasing requirements for control of integrated information-management system elements are caused by the need of application of communication protocols that are heterogeneous in terms of organization and control cycle duration. Thereupon, it is reasonable to use a set of error-controlled codes differing in redundancy, and processed on a common hardware platform, in similar systems to prevent errors in real-time information. To implement this concept it is expedient to use short block codes. They are applicable in the process of small data transmitting and they can be easily transformed to protect a large bulk of data using the cascaded coding technology or on the basis of product codes in 3D or in higher dimensions. The code sequences shortening at specified requirements in terms of data adequacy leads to a need of the flexible synthesis of information on signals received from a continuous communications channel and of soft iterative algorithms of the selected redundant codes processing. Polar code constructions meet this requirement. The paper offers to use the proper code combinations space clustering in order to reduce the polar code combinations processing time interval. The text gives valuable information on a clustering mechanism and cluster number security variants when transmitting over a noisy channel. The authors present the results of polar code decoding simulation models testing using different algorithms that demonstrate the benefits of the proposed data processing method under conditions of low signal-to-noise ratios compared to canonical schemes required for redundant code decoding.

An Analysis of Radar Data Multiplexing, Time and Spatial Bindings 39_3.pdf

The article deals with common approaches to the designing of trajectory data processing system. Fundamentals of maneuvering target trajectory parameter estimation are presented. The software is developed in which two types of trajectory processing are realized and compared in effectiveness. The first type includes standard trajectory signal processing for each type of measurements. The second type supposes integration of all measurement results. The estimation of time and spatial bindings using proposed algorithms is analyzed. The straight-line object motion and maneuvering modeling for data multiplexing algorithm is carried out to perform a comparative analyzes for the proposed algorithms. A procedure of accounting the data receiving time that ensures data load-time binding is proposed. These results can be used for developing software that combines radar data flows in an effort to cluster all changing conditions.

Energy Efficient Terminal Control of the Direct Current Servomotor 39_4.pdf

An optimal (on consumed power) segment length of terminal control of servodrive with a DC motor with zero initial and finite speed is determines. The optimal segment length of terminal control is related to the angular load displacement and the joint inertia. A new calculation formula for the optimal period of terminal control. The dependence of power consumption on the terminal control segment length is investigated.It has a unique minimum at given initial and final conditions and given characteristics of the servodrive. The formula is obtained that allows to evaluate the minimum energy consumption in DC servomotor terminal control. The parameters of the formula are determined by the characteristics of the servodrive, initial and final conditions. The possibility of approximation of the control signal and the angular speed of the servodrive mechanical load in energy-efficient terminal control is demonstrated. The control signal corresponding to the DC servomotor energy-efficient terminal control can be approximated a linear function of the time. The formula is obtained, that allows to calculate the maximum angular speed at the load shaft in energy-efficient terminal control with the DC motor servodrive.A structure chart of the automated control system of the DC servomotor with the terminal control block is presented. Diagrams for the transient processes in energy-efficient terminal and line control of DC motor is plotted.

Mathematical Modeling and Research of Filtering Algorithms While Target Data Tragectory Processing 39_5.pdf

The tracking of a maneuvering target in automated systems is a quite difficult task. A sudden change in speed of a target or change of its movement direction can have a major effect on the result of target movement parameters filtering. There are some methods of target movement characterization in statically indeterminate situations, at which conformities between measured and real objects positions are unknown, such as algorithms using Kalman Filter, multimodel filtering algorithms, and algorithms of intermodel interaction. The goal of this article is a research of algorithms for preliminary processing of target trajectories experimental data, intended for smoothing random interferences. The algorithm based on the spline smoothing function constructed by several trajectory points is also offered to be used to increase accuracy of maneuvering trajectory estimation in target tracking. This algorithm makes it possible to evaluate the intensive change of target movement parameters in case the dynamic movement model is not available, based on measured data and its approximation. The simulation of target movement parameters estimation algorithms proves that this algorithm provides a more exact result in comparison with algorithms using Kalman filter. In addition, this algorithm is quite simple to implement and requires not many computational resources. This algorithm can be used together with multimodel radar data processing algorithms.

Pixel-by-pixel Interframe Geometric Image Deformation Estimation in Assigning the Moving Object Area 39_6.pdf

The comparative analysis of different variants of implementation of pixel-by-pixel interframe geometric image deformation estimation by the example of the task intended for assigning the moving object area has been carried out in this paper. The projections and polar parameters of the reference image have been studied as estimated parameters of shift vectors of its points corresponding to the nodes. Two estimation techniques for the shift vectors field are proposed. In the first case, a pseudogradient algorithm sequentially processes all nodes of the reference image line by line. Each line is processed by the pseudogradient algorithm bidirectionally (“from left to right” and “from right to left”). The coprocessing of results allows compensating the inertia of the recursive estimation. The second technique studies the possibility to increase the processing efficiency by taking into account the correlation of image adjacent lines. The lines are processed one after the other with change in direction after each line. The resultant estimation is made of two values received for each node of the reference image. Two criteria for making the estimation are researched, namely Mean square difference and correlation coefficient. The computational effect is estimated in implementing the techniques proposed.

Evaluation of Object Status Diagnosing Efficiency to Non-random Structures Existance on the Hotelling’s Chart 39_7.pdf

The status of a technical object is often considered emergency if the stability of its operation is broken. multivariate Hotelling’s charts can be used for diagnostics of stability disruption on set of the correlated parameters. The basic criterion of the process stability in this case is the absence of the points above control limit on the chart. However, this criterion does not allow to find out process disruption promptly. For the purpose of increasing sensitivity of the chart to possible failures, it is offered to reveal the presence of nonrandom structures on the chart (the arrangement of points that indicates the process disruption). One more possible way to increase the effectiveness of the control is to use the warning border (the several points that hit in a range between warning and control limits and testify to the process disruption).The effectiveness of these methods is investigated analytically and with the use of statistical tests. The sensitivity substantial increase to possible process disruption is shown by example of the concrete technological process of manufacturing a cover of the sensor of aerodynamic corners.

Workflow Data Modeling for Analysis of Multidimensional Statistical Control Effectiveness 39_8.pdf

The multivariate statistical control of the technological process is usually spent with the use of the Hotelling’s chart. If necessary, the generalized dispersion card is used in the process control disruption. Efficiency of the control is evaluated by means of average run length. It is the number of observations from the moment of the process disruption till the moment of the detection of this disruption.For the purpose of increasing the sensitivity of the control to possible disruptions various approaches are used: the analysis of the special kind of structures on the chart, application of the warning border, modification of charts on the basis of algorithms of cumulative sums and exponentially weighted moving averages and others. Thus the average run length sometimes can be determined analytically and more often it has to be estimated with the results of statistical tests. To carry out such tests the sequence of data vectors of technological process is modelled and also various kinds of disruptions are set. Data modeling is offered to implement on the basis of the multivariate normal disruption with the subsequent parameters check. Spasmodic displacement of an average process level and its trend and also spasmodic and gradual increase of the process dispersion are guarded as the basic process disruptions.

Multivariate control chart, statistical tests, average run length, sequence of data, process disruption.

Numerical Method for Solving a Class of Nonlinear Boundary Value Problems of Aerohydroelastity 39_9.pdf

On the basis of nonlinear models proposed and a numerical method developed for solving corresponding boundary value problems in nonlinear integro-differential equations static instability (divergence) of the pipeline with the fluid flowing in it is investigated. A numerical method for solving the bifurcation problem includes the Runge-Kutta 6-th order method with the error control at each step, Newton's method for solving nonlinear equations and integration with the use of Newton-Kotesa quadrature formulas. Solving the boundary value problem is reduced to solving a Cauchy problem. The complexity of a Cauchy problem is that there is an integral term in the equation. Calculation of this term needs values of the whole integration interval. It makes the direct application of the Runge-Kutta method impossible. To solve this problem (integration) a special iterative process was developed. Numerical realization is provided with the use of a program written in Delphi 7. Bifurcation diagrams showing the dependence between maximal element bending and the inflow velocity are obtained. Moreover, the element’s forms of deflection are specified. The obtained numerical solutions were compared with analytical ones.

Mathematical Modeling in the Problem of Dynamic Stability of a Pipeline 39_10.pdf

The paper presents mathematical models for a viscoelastic pipeline that is a hollow rod containing flowing the fluid (gas). The article is devoted to the problem of the dynamic stability of a pipeline. Linear and non-linear models describe partial differential equations for an unknown function (the displacement of the pipeline points from the equilibrium state). By means of Lyapunov functionals designed stability theorems are formulated and analytical stability conditions for the parameters of the mechanical system and different types of initial conditions are found. The obtained stability conditions are sufficient but not necessary. A mathematical software package is developed to solve this problem. It allows to find an approximate numerical solution of differential equation for describing pipeline vibration and to plot a stability area appropriate to both sufficient and necessary stability conditions. A numerical experiment of stability areas designing is conducted on the basis of the software package. The obtained numerical results are interpreted and compared with analytical stability conditions. The influence of the model parameters variation on the stability is researched.

Pseudocode Programmable Graphics Tools in Automated Systems Designing 39_11.pdf

The article presents the tools for the pseudocode programmable graphics designed for support of automated system engineering at a conceptual stage. The particularity of the approach offered is defined by mapping «block and line» diagrams into a semantic memory of question-answer type. The structure of memory cells and capability of control of cell attributes and values ascribe the semantics, with which programmable actions are liable to occur, to elements of diagrams. The specific diagram image can be converted to a pseudocode program description that can be modified the same way as a source programme code. In addition, the pseudocode diagram presentation can be used for its visualization in the special graphics editor field. Furthermore, mapping the diagram onto its pseudocode presentation offers the opportunity for useful conversions of diagrams that contributes to add model control mechanisms to the design process. The decisions offered have been implemented and tested in the tool-and-modeling environment WIQA (Working In Questions and Answers).

Error Estimation of Thermal Conditions of Measurement Trancdusers With Differential Connection of Sensors 39_13.pdf

The main sources of errors of transducers with sensors differential connections caused by the distinction of thermal conditions of the sensing elements work are considered. Expressions for the distinction of sensors temperature in static and dynamic modes of operation caused by both the distinction of sensors parameters heat and the power dissipated by sensors are obtained. It is shown that instant at grading of the converter with various thermal time constants of sensors the thermal nature error reaches a maximum at a particular instant depending on the relation of thermal time constants. The thermal nature error can also significantly exceed the error in steady conditions.Errors of the differential photodiode are estimated on the basis of obtained expressions, and it is shown that the error of thermal conditions has multiplicative character and depends on the sizes of a light spot. For converters of bridge type the zero temperature drift is proportional to a difference of sensing devices thermal resistance. The more the total thermal resistance of sensors is the more, the more the size of temperature imbalance is.
