One of the most important components in the value of gemstones is how clean and free of inclusion the stone is. Based on the broad used technique of visual inspection, the designed expert system automatically checks the surface of the ruby samples and detects three main components: ruby, calcite and mica. Based on this data, the system was able to assess the amount of clean ruby surface of the specimens...
Intensive development of information systems has led to an increase in malicious software, which is associated with the emergence of new types of cyber attacks. Expanding impact of cyber attacks aimed at a variety of resources information system initiates creation of special countermeasures that can be effective in the emergence of new types of threats from unknown or ill-defined properties. There...
The statement was formulated and the mathematical modeling of the stressed-strained state (SSS) problem of the soil mass considering mass and heat transfer under filtering of salt solutions in the three-dimensional case was conducted. There is obtained the numerical solution of respective boundary value problem.
The paper studies the process of correlation for SIEM systems based on analyzing the structures of security event types. The approach to automated analysis of security events as input data with dynamic content is proposed. For the automated analysis of events the paper suggests to build a graph of types of events with direct and indirect links between them. Processing of security input data means...
The paper is devoted to the issues of design of secure cyber-physical systems based on embedded devices. It aims to develop a generalized approach to the design of secure systems based on embedded devices. Current approaches to design secure software and embedded devices are analyzed. The design lifecycle for secure embedded devices system is proposed. Advantages and disadvantages of the approach...
This work presents a mathematical model of a mobile robot based on a wheel-mover for the movement on nonlinear ferromagnetic surfaces. The paper consists of the original geometrical relationships between the magnetically-operated wheel-mover's components and an analysis of their properties. The authors created a simulation of a wheel moving on an arbitrary ferromagnetic surface (inclined and vertical)...
In this paper the water quality is explored using the fuzzy cognitive analysis. Fuzzy cognitive maps of Silov are used as a tool for analysis and modeling. The proposed method is based on the iterative calculation and analysis of system indicators of the fuzzy cognitive maps of Silov for a certain period of time. Presented a fuzzy cognitive map, calculated system parameters and the analysis of the...
The DCT is widely used in compression algorithms and image decompression. Perhaps decline their resource consumption by optimizing DCT. In article descried optimization by means of decomposition the DCT matrix (dimension n = 4, 8 and 16) into dolled up multipliers especially for minimization multiplication. Moreover, it is will allow lower cost for storage matrix in memory. Obtained by decomposition...
Security Information and Event Management (SIEM) solutions are expensive, difficult to handle, and still a further security system without interface to existing Network Access Control (NAC) or other security components of an enterprise. Thus, the research project CLEARER [2] aims at developing a security system, which extends existing NAC systems with SIEM functionality, additional analyzing methods...
Distributed system for sampling and analysis of electroencephalograms is proposed and implemented in alpha state. The system is based on the previously developed database for archiving of the electroencephalograms in Ukrainian National Grid infrastructure. The new components of the system include EEG sensors for laboratory animals, simulations software and data procession algorithms. The first application...
Software for simulation of large networks of coupled non-linear oscillators in clusters, grids and clouds using graphical processing units (GPU) was designed, developed, tested and applied for scientific simulations. The software provides easy integration of new oscillators' models support, dynamic load distribution between hosts' central processing units (CPU) and several GPU devices. Different GPU...
Internet of Things is deeply integrated into all aspects of human life. This is also the case in higher education as well. Introduction of different e-learning tools requires from teachers and students deep knowledge in new emerging techniques. In the article we describe a project oriented approach in studying and 3 case studies on how new technology can improve the e-learning environment in HEIs.
The paper is devoted to development of the computer-based specialized processing the meteorological data in order to analyze and visualize changes in local climate dynamics. In particular, we focus on local seasonal temperature evolution. The peculiarity of the discussed viewpoint is connected with the attempt to take into account variability of seasonal temperature compositions in correlation with...
There has been investigated the effectiveness of fermentation industry sewage waters clearing by means of ultrasound. There has been established that the necessary quality indicators of water are received in as little as an hour of acoustic cavitation activity. While preserving the water, processed by the ultrasound, the meaning of the chemical use of oxygen remained the same during 2 weeks. After...
Mathematical modelling of the salt movement process under filtration salt transfer considering infiltration process in unsaturated-non-saturated layered soil has been carried out. The solution of this problem was received with a finite difference method. As a result of program implementation of the problem, numerical experiments have been performed and an analysis of the results has been done.
The experience of cloud-based computing technologies use in the Smart City class design is analyzed. In the considerable part of applications in the Smart City class design informational technologies of cloud-based computing combined with such technologies as GRID, IoT, BigData, OLAP, GIS are used. At the same time complex solutions systematically considering peculiarities of defined technologies...
Obtained during reporting period important results are considered as new for science. Up to now there were not any publications describing species composition of fauna and ground beetles of European area of Arctic ocean during the whole season. It is ground beetles that represents bright indication of ecological situation change in circumpolar region. For the first time we compiled a close to comprehensive...
Literature analysis shows existence of data about weather influence on man's diseases. Selection of diseases in Arkhangelsk region from multifunctional information system was made. Analysis of people prevalence in several human settlements of Arkhangelsk region by means of statistic methods was conducted. The analysis demonstrated dependence of people prevalence on weather conditions as follows: a...
Preservation of biological diversity is one of priority tasks of the present time. Monitoring of the population during the migration from Europe and nesting on the coast of the Arctic Ocean plays an important role in the protection of European geese population. Traditionally, the main methods of geese population monitoring are those of route and area recording. The authors propose to study geese populations...
The process of human adaptation to the Arctic conditions is accompanied with changes in psychophysiological indicators such as strength and mobility of nervous processes. Extreme conditions have a strong impact on a human brain. This effect is different for people with different laterality. Laterality indicates functional asymmetry of two brain hemispheres. The authors propose software-based evaluation...
