Some issues of organization of restoration of railway infrastructure facilities62_3.pdf

The Railway Troops of the Armed Forces of the Russian Federation are intended for technical cover, restoration, demining and barrage of sections (objects) of the RF railroad transport infrastructure in the RF Armed Forces responsibility zone, increasing its survivability and carrying capacity, as well as planning the guidance and operation of floating railway bridges. The railway infrastructure is understood as "a technological complex, which includes subsystems of railway infrastructure, components of subsystems and elements of components of subsystems of railway infrastructure, ensuring the functioning of this complex" [1]. The tasks of the troops include the operation of existing and construction of new sections of railways, bypassing railway (railway) junctions, the construction of temporary railway bridges in order to ensure the actions of troops [2]. When restoring infrastructure facilities for railroad transport, the organization of work management and the promptness of restoring interrupted train traffic play a decisive role, which largely depends on the preparation and decision-making that requires certain engineering calculations. In particular, the development of design documentation for the construction of a bypass of a destroyed section of a road or a railway junction requires a significant amount of time. The most time-consuming document of design documentation is the calculation and construction of a longitudinal bypass profile. The article discusses the issues of automated construction of a longitudinal bypass profile, which can significantly reduce the time required for preparing design documentation, including for laying cable lines to restore the regulation of train traffic.

Railway transport infrastructure, restoration of infrastructure facilities, longitudinal bypass profile, information technology, computer-aided design, automation of calculations, mathematical methods, software.

Calculation of safety index for foreign origin electronic components62_4.pdf

The article deals with problems arising from the use of foreign origin electronic components, being off the line in standby (storage) mode during operation with periodic monitoring of their operability, as well as with possible ways to solve these problems. It proposes the method of assessing the safety index based on determining the characteristics of foreign origin electronic components for the standby (storage) mode. The method is implemented using mathematical models with the activation energy of physical and chemical processes of electronic components degradation. The use of mathematical models to solve the problem may allow forecasting the reliability of products in the most efficient way. The authors give calculations and comparative analysis of the minimum service life (minimum shelf life) at an elevated temperature for several groups of foreign origin electronic components and for several models of external influencing factors.

Logistic support for operation of computer-aided tools of the specific-application control systems62_2.pdf

Complicating functions of computer-aided tools of specific application control systems prioritize the task of keeping a high- degree alert performed by the operations services in the presence of component failures. Besides its primary function, the operations service provides the logistic support, maintenance and repair, storage, etc. Thus, it includes all the functions of the logistic support system. The article deals with such problems of the logistic support as planning, preparing and delivery of spare parts used to repair and recover systems. The authors analyzed customer’s requirements, which ensure stable operation of the specific application computer-aided systems. They discovered that one of activities intended to meet the customer’s requirements is preparing spare parts, which provide the operational onsite repair. Currently there are no governing documents specifying the procedure of spare parts preparation. The article proposes an approach to preparing optimal quantity of spare parts based on failure statistics over the past period and forecasting the number of possible failures over the planned period of time. The authors propose the widely-known method of exponential smoothing as a forecast model, which allows giving an unbiased estimate both for stationary time series, and for polynomial ones.

Suggestions for kill performance forecasting of various objects afloat at the shortest time62_1.pdf

The paper suggests ways to enhance the operational and tactical calculation complexes forming a part of the decision- making support system for naval strength employment. These ways comprise automatic forecasting of kill performance of objects afloat at the shortest time. It gives analytical calculations determining space and time parameters for planning of destroying enemy’s surface combat formations afloat by maneuvering combat formations of surface action groups. The combat formations are supposed to use these parameters to approach to enemy’s forces maneuvering beyond their reach in order to provide an effective engagement range. The paper describes an algorithm of possible optimal allocation of combat formations per objects to be destroyed. It also suggests an algorithm of automatic generation of proposals to the object-destroying schedule including required ammunition calculations employed to destroy an object in order to comply with required level of decision-making effectiveness. The authors give the results of space and time parameters calculations using the module for computer-aided construction of the shortest deployment route.

Fractal clustering of group codes in the system of galois field62_9.pdf

The permutation decoding (PD) of group systematic noise-immune codes is proved to be the most efficient method in using the redundant data entered to the code as against other methods of decoding digital data [1-5]. This opens up the opportunity of solving a complex computational problem of finding an equivalent code (EC), which is used to search for the error vector. The essence of this solution is that the computational procedure of real-time search for EC for each new combination of redundant code is replaced by a preliminary process of training the decoder to put in accordance with each new permutation of characters the generating matrix of EC parameters, which are recorded in the decoder’s memory card during training. Thus, such a memory card is called a cognitive card (CC). The article estimates the memory size of the CC, when using the block code (15,7,5), and shows the possibility of implementing a permutation decoder on basis of existing integrated circuits based on proven statements. For the first time, the apparatus of fractal partitioning of augmented binary Galois fields using the clustering of the common space of code vectors of a given code is used to prove the main statements. An efficient algorithm is presented to search for a set of invertible matrices of rearranged codes that do not provide an EC and for this reason should be primarily detected in the decoding procedure of the received code vectors.

Reduced input redundancy while providing the stability of information-analytical systems in compensating the effects caused by attacker’s destructive actions62_5.pdf

The article describes the information and analytical systems (IAS), the main function of which is processing of large multidimensional arrays of information under conditions of destructive effects caused by attacker. Such conditions require the management of secure data storage. It ensures the data sent for storage by operator is identical to the one used by a decision-maker upon request. The authors propose the subsystem of data integrity control that uses cryptographic hash functions. The applied hash functions are based on the rules for constructing Pascal’s triangle. The paper shows that a distinguishing feature of the subsystem is reducing the input redundancy of control information at a given security level of data processed in the IAS, as well as ensuring new properties, such as the ability to control the integrity of not only the data to be secured, but also the reference hash codes. The article also gives a comparative assessment of the developed subsystem with known methods of data integrity control.

The game model of information conflict between the communications system and the system of destabilizing effects62_7.pdf

The article proposes a model of information conflict between the application specific communications system and the system of destabilizing effects based on the game theory formalism. The model takes into account strategies of destabilizing effects and of communications system protection, as well as their change during the information conflict. It shows that based on the game with direct or mixed strategies, it is possible to substantiate the most probably variants of destabilizing effects, as well as the rational structure of communications system in the conflict. The authors propose decision-making formalized by the opposing parties, when choosing strategies at each stage of the information conflict. The paper describes the rules for choosing the strategy of protection and corresponding structure of the communications system in the form of a minimax criterion. These rules allow searching for a rational structure of the communications system both in the current and in the preventive decision-making for countering the system of destabilizing effects.

Substitution characteristics of factorial sets and criteria for choosing the single substitutions62_12.pdf

The substitution and permutation function, which are presented in the article as elements of a number of factorial sets, are the key functions of cryptographic systems that provide diffusion and mixing of information. A new scale of notation is proposed while analyzing this problem. This is the notation scale of a number of factorial sets. This scale of notation helps to index the elements of a number of factorial sets and establish a one-to-one correspondence between the number and a specific type of substitution. This allows analyzing substitutions characteristics systematically. This paper presents the basic concepts of a number of the factorial sets. It is noted that the permutations of the factorial sets form symmetric permutation groups, and specific permutations (when raised to a power) form cyclic groups. The group axioms are fulfilled for the permutations of a number of factorial sets. Also, the definition domain, the group operation of multiplication, and identical and inverse substitutions are given for them. The number of independent cycles, decrement, inverse, parity and sign are common characteristics of the substitutions of a number of factorial sets. The criteria for choosing single substitutions with the best characteristics are proposed.

Substitution, a number of factorial sets, a number of insensitive cycles, decrement, inverse.

The hypothesis test of covariation functions of quasiperiodic processes systems represented by cylindrical image models62_10.pdf

The generally accepted mathematical model of a wide variety of natural, technical, economic and other objects that exist in time are random processes, for example sea waves, wind, vibrations of engines and hydraulic units, biorhythms, etc. An object is usually described by several parameters, that is a system of random processes or time series. The processes occurring in many objects have a form close to periodic – quasiperiodic, namely there is a periodicity with an element of unpredictability, for example speech sounds, vibrations of various technical objects, daily temperature fluctuations, etc. In order to formulate the problems of processing the quasiperiodic process systems, their mathematical models are required. For this purpose, authors propose models in which the processes are presented in the form of spiral sweeps on autoregressive cylindrical images. A suitable set of parameter values for these models provides a given degree of quasiperiodicity of individual processes and the given covariance relationships between the processes of the system. A criterion is proposed for testing the hypotheses about the correspondence of the observed system of time series to their model of the described type. The authors provide the examples of the application of this criterion with an analysis of the sensitivity to deviations of the model parameters from the expected ones are given.

Quasiperiodic process, covariance function, hypothesis tests, criterion, significance level, test power.

Program development for designing simulators of advanced flight electronic support systems62_14.pdf

The main radio equipment used by aviation specialists are communication, radar and radio navigation systems. Training of students in these areas is a complex task that requires significant efforts of lecturer. The article proposes a concept of simulator designing that are supposed to be adopted in the educational process of civil aviation institutions based on hybrid approach to the virtual simulators designing. Such concept was applied in the development of methodology for designing of simulators for flight electronic support, which involves solving the problem of selective structural synthesis. The problem of selective structural synthesis of design solutions is described using a morphological tree and implies finding the graph edge that ensures meeting a set of rules with the constraints specified in the process of specification drawing up, which is replenished by the developer-user. Due to random nature, the structural optimization method implies a sequential search for possible options. A computer-aided system of simulator designing for flight electronic support systems was developed based on the methodology. The development of a computer-aided system of simulator designing for radio communications, radar and navigation equipment makes it possible to provide effective training of future pilots and air traffic control officers.
