Architecture Optimization of Functions of Airborne Equipment Complexes on the Basis of Integral Modular Avionics 000_3.pdf

The article deals with the process of designing of an airborne equipment complex based on integrated modular avionics. For a more complete disclosure of the advantages of the new architecture of the complexes, the authors propose to single out the process of designing the architecture of the product functions in the form of a tree in a separate stage. Taking into account that the design process of the complex is closely connected with the process of assessing its security at all stages, the article shows that the design of the product function architecture should be intermediate between technical analysis and safety analysis and the process of circuit design of the product. That allows to perform a primary assessment of the product fault safety level, formulate requirements for the application of methods in order to increase its reliability and fault safety at the early stages of design. Optimization of the architecture of the product functions also allows to justify the hardware requirements of the complex.

On Application of Elliptic Curves in Some Verifiable Protocols of Secret Sharing 000_4.pdf

The threshold secret sharing is the secret sharing with n participants for the structure of access in which all coalitions supporting at least t participants for some t are authorized, and all coalitions with smaller number of participants are unauthorized. The special role is given to perfect secret sharing schemes in which shares of a secret of any unauthorized coalition don't allow to obtain any information on value of a secret. One of well-known perfect secret sharing schemes is the Shamir's one. In the Shamir's scheme, the dishonest dealer can distribute incompatible shares from which they will never recover the initial secret to participants. In this case, the checked secret sharing schemes are applied. Such schemes allow each participant to check compatibility of the share with shares of a secret of other participants. For this purpose, complementary to a secret share, some additional information allowing to check the given secret share is transferred to each participant. The well-known checked schemes are Feldman-Shamir's one and Pedersen-Shamir's one. Pedersen-Shamir's one is perfect. Modifications of Feldman-Shamir and Pedersen-Shamir schemes on elliptic curves which application allows to reduce considerably the sizes of parameters of protocols and to increase their cryptography firmness are considered.

The Automated System of Coding and Classification of Production Objects 000_7.pdf

Increasing efficiency of design and technological training in conditions of multi-nomenclature serial production can be ensured by coding and classification of parts. Therefore, the paper provides theoretical substantiation of classification characteristics of parts and their grouping. A method for coding details is proposed, in accordance with which details are assigned an impersonal code of its design characteristics according to the United Design Documentation System (SUDD) classifier. Technological characteristics of the parts are coded in true values from the drawing. In practice, the technique was implemented when creating a regional data bank about details that contains information on 150 thousand items. The article shows the functional-structural scheme of the automated system for coding and classification (ASCC) of parts, consisting of four subsystems: coding of parts, generalization of parts characteristics, selection of design solutions, output of technical documentation. At industrial enterprises, ASCC allows to significantly increase the labor productivity of designers and technologists in the preparation of production and the quality of the design decisions they make.

Development of the Algorithm for Defining Wind Parameters Ultrasonically 000_8.pdf

This paper considers the option of constructing an ultrasonic sensor of wind speed and direction with changing the operating time of sound passage in the atmosphere, depending on the speed and direction of motion of the medium. The variant of placing ultrasonic emitters and receivers allowing to exclude affect of temperature, humidity and atmospheric pressure at the speed of sound is proposed. The paper describes the algorithm which allows to find the wind speed and direction from the data on sound propagation time. The algorithm also allows to determine the wind speed and direction with the same accuracy regardless of the direction of air flow. The sensor described in the article has not any moving parts which improves its reliability and excludes the influence of atmospheric parameters on the speed of sound, that makes it possible to use such device in a variety of climatic conditions and obtain wind speed and direction with the same accuracy.

The System for Modelling the Cluster Simulating Processes of Big Data Analysis 000_9.pdf

The subject area for processing Big Data with the use of cluster systems is described in the article. The paper examines the existing methods of processing Big Data on which the proposed solution for increasing the efficiency of the cluster functioning is based. As basic solutions for building and proposing ways to increase the efficiency of the cluster, the Hadoop technology and the MapReduce methodology were chosen. The efficiency of cluster systems involves consideration of cluster processes in the form of the hierarchical architecture consisting of three levels: cluster node level, cluster segment level and cluster topology level. The paper indicates solutions that can be useful in order to improve the efficiency of cluster resource allocation by choosing the topology of cluster construction, using the more efficient load-balancing algorithm, and using graphics processors, which involves distributing computational loads between CPU and GPU. Recommendations proposed in the article are verified experimentally.

The Complex of Ontological Support for Processes of Solving New Design Tasks in Development of Systems With Software 000_11.pdf

The article presents a method of ontological support increasing efficiency of project thinking, when in the development of a software intensive system, the designer discovers the need to solve a new design task. Support is provided in the conditions of application of the version of the project thinking, in the processes of which the means of question-answer and case-oriented approaches are included, which ensure the constructive formation of the project task tree. The components of the tree register not only the texts of task statements but also the question-answer reasoning of the processes of solving each task. The proposed method of ontological support is aimed at the search for design errors, their correction and prevention, as well as on the extraction of useful questions and support of understanding processes in the design process in real time. In addition, it allows you to identify in the texts the cause-effect relationship and the «part-whole» relationship. The basis of the proposed method is the use of question-answer and precedent-oriented approaches to work with the project task, the formulation of which is built in the process of its conceptual solution.

Neuro Network Model and Software Package for Human Functional State Determining 000_12.pdf

The article considers the problem of determining the functional state of intoxication of a person. For its solution, the authors propose a method based on the analysis of data pupillograms - time series characterizing the dynamics of changing the size of the pupils of the person on light-pulse exposure. As a tool for data mining and model building in order to determine the functional state of the person the authors propose to use the mathematical apparatus of artificial neural network - single layer perceptron. The original neural network model is proposed, and its adequacy is evaluated. In order to improve the efficiency of its practical use, a method of reduction of a neural network structure based on genetic algorithm is being developed. The proposed method is a two-stage genetic optimization that allows to determine the significant input features for a neural network on a given input feature space in order to optimize the structure of neurons in the hidden layer. The results of the experiments on the basis of the developed program complex have shown high efficiency of determination of the person functional state based on the reduced neural network model. The model can be effectively used in intelligent surveillance systems in public safety systems, as well as in medical diagnostics as a tool for contactless determination of the functional state of intoxication of a person.
