Abstract: The object of research is the dynamic characteristics for target groups of social networks. The subject of this study is to analyze the methods and models of the evolutionary characteristics of the social graphs of large dimension. The study examines in detail the approaches of analysis, quantitative characteristics graph models. Synthesized an algorithm to analyze the dynamic characteristics for target groups of social networks. The experimental results show the fact of adding a user to the subject area of interest, as well as visualize the entire process in real time. The developed software tools can be useful for further development and research topics related to the social network. When solving tasks used methods of mathematical logic, graph theory, mathematical statistics, the apparatus of mathematical analysis, linear algebra, mathematical modeling methods, theory of algorithms, as well as object-oriented programming techniques. The novelty of the study is to determine the dynamic characteristics of the target groups of social networks, as well as the visualization of the entire process in real time. The main conclusions of the study is that the developed software tool will enable to trace cause and effect indicators of changes in the social graph. The proposed prototype of the software will be of interest primarily marketers, system analysts, and professionals involved in the analysis and the study of social networks.

Abstract: Modern systems of computer vision use intelligent algorithms that solve a wide class of problems from simple text recognition to complex systems of spatial orientation. One of the main problems for developers of such systems is in selection of unique attributes which remain invariant to various kinds of transformations. The article presents a comparative analysis of methods of detection and spatial localization of groups of point objects. The reviewed methods are compared by the performance and efficiency at specified dimensions. As of today there are no universal approaches to determine of such attributes, and its’ selection depends on the context of the problem being solved and on the registered conditions of observation. Various kinds of descriptors such as points, lines, angles and geometric primitives can be selected as dominating attributes. The authors study  algorithms for detection of groups of point objects based on the minimum spanning tree (MST) and using a model of associated continuous image (ACI).

Abstract: The article discusses the question of automated processing and analysis of the gels images gathered as a result of electrophoresis of samples containing products of polymerase chain reaction (PCR). The proposed approach allows to significantly increase the speed of the DNA-analysis. The authors state that one of the  resource and time-consuming stages of the forming of initial data is the analysis of digital images of the results of chemical reaction. The article reviews the development of necessary theoretical methods and practical implementations of automated image analysis. It is noted that one of the  resource and time-consuming stages of the forming of initial data is the analysis of digital images of the results of chemical reaction. The presented development of an automated system based on the methods of pattern recognition and analysis of digital images of gels allows to minimize the time-consuming operation performed manually and to increase the quality of the result. The article brings the algorithm for automated recognition and assigning of unique lines that define the field of primers and products of PCR. Comparative analysis of the manual methods and created approach shows that the automated system is one and a half order of values faster. The massive usage and accuracy of this method also increases the economic benefits from the use of this product.

Abstract: In this paper we propose a new systematic approach to monitor forest fires over large areas. Established architecture of the complex, as well as effective methods of centralization and decision-making. Scientific and technical challenge is to create a system of distributed video surveillance to solve the problem of early detection of forest fires. This article discusses the existing fire detection approaches: the use of specialized towers, fire detection methods from the air, with the use of aircraft of various classes, a holistic approach to forest fire monitoring system uses satellite monitoring, video monitoring system. The described system is designed for the detection of forest fires and the determination of their spatial coordinates in real time. For the operation of the software complex towers and existing infocommunication data transmission medium can be used. This article analyzes existing approaches in the field of forest fire monitoring. A new systematic approach to problems of this kind, which is characterized by high performance and maximum efficiency of the concept solutions with minimal resource costs.
