A Method for Protecting the Information-telecommunication Networks At Objects Being of Critical Importance Against Computer Network Attacks 51_2.pdf

The article deals with the problem of providing security and protection of information in information-telecommunication networks. It is well known that in order to ensure safety and information security, it is necessary to identify facts of hacks on computer networks with a high probability. There are a large number of systems and methods for detecting the destructive software attacks on a protected network. However, the existing technical solutions do not allow to achieve the required detection probability and recognition of types of destructive software attacks aimed at complex traffic shaping. The authors propose a way to protect the information-telecommunication networks against the effect of destructive complex traffic patterns through the introduction of a new distinction for detecting the class of computer network attacks and fixing it in time. The method provides an adaptive correction of the established access control rules taking into account the objective parameters of served traffic for the conservation of probability-time characteristics of subscriber service quality without increasing the performance of computing resources at the communication node.

Objects being of critical importance, information-telecommunication networks security, protection against computer network attacks, destructive complex traffic.

Effectiveness of the Use of Aviation Telecommunication Systems When Ensuring Flight Safety 51_3.pdf

The performance of any process, system, or device is a relationship between an achieved end result and resources that were spent on achieving this result. This review addresses to the effectiveness of an air traffic management system in regard to its telecommunications software. The ensuring of flight safety while maintaining a specified level of regularity and efficiency of aircraft operations is an ultimate goal of the air traffic management and its component parts of air traffic control. In this case, it is necessary to find the relationship between the indicators characterizing the ultimate goal of air traffic control (flight safety) and the telecommunication resources used. In the general case, it is best to solve this task sequentially in two stages. At the first stage, to estimate the effectiveness of the use of the flight-operations telecommunication systems of aircrafts, i.e. to select indicators characterizing their ultimate goal and find a correlation with the telecommunication resources used. At the second stage, the indicators characterizing the ultimate goal of the use of telecommunication systems can be considered as resources for determining the values of indicators characterizing the ultimate goal of air traffic control (indicators of the level of the flight safety management). This research paper examines the first stage of the mentioned approach, i.e. it assesses the effectiveness of the flight-operations telecommunication systems of aircrafts through the use of telecommunication resources. Frequency-domain and energy characteristics are considered as such resources. Probabilistic characteristics of these contacts are studied taking into account the stochastic nature of telecommunications contacts.

Mathematical Models of Hierarchical Systems Information Space 51_7.pdf

The article deals with the ability of the mathematical physics methods application to the modeling of hierarchical systems information space. The information space is created with the situation information flows from objects of the lowest hierarchy level and the arrangement flows from upper objects. Spatial coordinates reproduce the hierarchical levels and the structural units of objects. A knowledge level at a certain place and in a particular time is selected as overall performance of information space. A two-dimensional model of noninteracting information flows is built. The model is created with a set of parabolic equations that reflect the data distribution through the structural units of objects of different hierarchy levels. The application of the partition method for solving problems under homogeneous and nonhomogeneous boundary conditions is described. The examples of information wave distribution in a system at periodic external interferences are provided. The two-dimensional model of interacting information flows is represented by partial differential equations with two spatial coordinates. The problem-solving procedure in stationary and nonstationary cases under certain boundary conditions and external interferences is shown.

Methods and Means for Measuring the Thermal Resistance of Integrated Circuits 51_10.pdf

The article deals with methods and means for measuring the thermal resistance of integrated circuits. The standard measuring methods and a modulation method using heating power varying harmonically are compared. The operation principles of thermal resistance meter based on the modulation method, its software and functionality are described. The results of thermal resistance measurements obtained according to the Industry Standard OST 11 0944-96 (method of constant die temperature) and with the use of modulation method are represented. The results of both methods were demonstrated to go with each other within the standard method accuracy. It is indicated that the ability to measure not only the total resistance ”junction-to-case” but also individual thermal resistance components, e.g. the “junction-chip carrier” components, is a merit of the modulation method. This could be used when testing the quality during mounting the die into the case.

Application of Fuzzy Models in the Analysis of Processes in Organizational-technical Systems 51_11.pdf

The article discusses the application of the Fuzzy models for time series analysis. The main aspect of the analysis is the formation of groups of similar processes. For the grouping of processes, they are considered in the form of discrete time series. Traditional methods for clustering time series based on point-by-point clustering, on attributes or models, do not take into account the nature of the behavior of the time series, which ensures the information content and quality of clustering. To solve this problem, a clustering algorithm based on a fuzzy approach, called Fuzzy Behavior Clustering (FBC approach), was proposed. The proposed time series clustering approach considers the behavior of time series at three levels of the hierarchy (at the level of the general tendency, the level of the parameters and at the level of values). The behavior of time series at the level of the main tendency is described by means of linguistic terms. At the heart of the FBC-approach lie a fuzzy representation of time series and an algorithm for a linguistic assessment of the main tendency. The application of the FBC-approach for analyzing and clustering time series of KPI dynamics of IT project developers based on data from the repository is provided.

Fuzzy behavior clustering, fuzzy clustering behavior, combined clustering of time series, the linguistic terms, extraction of fuzzy tendencies of time series.

Technical State Control of Complex Systems Via Fuzzy Model 51_12.pdf

The paper describes the management method of industrial equipment technical condition based on heterogeneous data systematization using a mathematical apparatus of fuzzy sets. The paper presents a fuzzy model for describing (estimating) the object technical state. This model allows a single way to process different types of information about an object and bring it to a unified form. The paper describes physical meaning of universal indicator of the object state - Technical State Index (ITS) in the view of fuzzy sets theory. The parameters dimensionality reducing method is proposed for multicriteria analysis. The problem of objects ordering (ranking) is solved. A fuzzy structural-parametric model for intellectual decision-making support in the technical state control of complex systems (including industrial equipment) consisting of many composite elements with unique parameters is proposed. The algorithm for calculating ITS of complex technical systems is considered. The up-to-date approach described in the paper will allow to apply computer information processing methods for implementation in problem-oriented control systems and decision support systems to increase equipment reliability and management efficiency. The paper presents the results of the proposed method implementation as equipment technical state management information system of gas transportation enterprise. Conclusions are formulated and prospects of further scientific research in this field are reflected.

Matching of Project Alternatives to the Main Aircraft 51_13.pdf

A method for matching design alternatives is proposed, it is based on the consistent application of correlation, factor analysis with the subsequent construction of polynomial models by the least squares method and the Brandon method. A multiparametric approach to the analysis and synthesis of the design solution variant is formulated, based on the formalized process and allowing to realize the uniqueness of the solution for individual elements (on the example of the wing) of the main aircraft, at the stage of the preliminary design. A technique for taking into account the influence of the characteristics of one design alternative on the other and their transfer to calculations at the stage of preliminary design of the main aircraft is proposed. The set of obtained polynomial models is seen as a transition function, on the basis of which it is possible to construct a surrogate model that allows data generation on varieties of smaller dimension to solve non-standard design problems as part of a complex technical system - the main aircraft or its element in the appearance.
