Abstract: The article deals with the issues related to the users’ access to the system of topological PC board layout without buying the license for the system because the price of the license may reach dozens or even hundreds of dollars which is not of economic benefit to the majority of developers. This leads to the growing popularity of cloud technologies that allow to get access to the design systems based on inexpensive licenses. Thus, the authors of the present article analyze different services of cloud CAD and define the most popular services. Then the authors compare different kinds of CAD PC board layout and offer to use Topological Router as the topological router created on the cloud. According to the author, Topological Router has the most beneficial features. In addition, the authors define the platform for deploying the cloud. The main research method used by the author is the comparative analysis of parameters and features of CAD PC boards and cloud deployment platforms. The scientific novelty of the research is caused by the fact that so far there haven’t been any practical implementation of WEB-oriented PC board design systems. The test case of the corporate cloud on the basis of the VMware platform has proved it possible to use cloud technologies in creating public access to the topological CAD. To deploy the full function corporate cloud and provide access to virtual CAD through web-interface it is necessary to install the additional server VMware vCenter Server 5.5.

Abstract: The primary objective of the interloper is to keep a swarm of robots from performing their functions by any means including their destruction. The primary goal of the information security system is to provide the proper security level for the swarm of robots against any natural or artificial hindrances for it is necessary to take into account not only the information safety but also physical security of actors. For the physical security of a wide range of facilities (the authors offer to call them 'facilities under potential interloper's influence or FPIP) it is very important to prepare the list of potential threats, especially design threats. The list would allow to design a necessary system for the physical protection of a particular facility and to evaluate its efficiency. The composite element of the design threat is the interloper modeling and therefore development of such a model is a high priority. According to the guidline documents, the interloper model should be based on both the featurs of the facility and performed technological operations (stable factors) and variable factors, i.e. social conditions of the territory where the facility is located, social relations, psychological traits of a particular group of workers and/or individuals as well as the global, country's, regional environment, etc. Therefore, the model should take into account all kinds of factors that are related to various aspects of the reality and often divorced from one another. The authors of the present article analyze the offered interloper models from different points of view. Nevertheless, these models are interconnected, so examination of these connections is one of the goals of the vulnarability analysis. In case the obtained characteristics of the operational interloper model are below the desired characteristics of the design interloper model (for example, the number of interloper agents that can be potentially involved in the destructive activity is lower than the number of interlopers which activities are to be prevented by the designed Information Security System according to the design project prescribed for the facility, i.e. Z>Ó), then the decision about sufficient facility hardness can be made meaning there is no need to perform unscheduled actions (facility vulnarability analysis with ISS performance evaluation, improvement of ISS, changes in the task execution technology, etc.).

Abstract: The subject of the research presented by the authors of the article is the mathematical models of endocardial signals from the main electrophysiological parts of the heart with the specified amplitude-time characteristics of information fragments. The authors of the article offer the mechanism for extending the mathematical models in order to generate normal and/or pathological states of the atrioventricular system conducting endocardial electrical impulses. The article contains the results of the comparison of modeled and actual endocardial signals recorded in the course of minimally invasive eletrophysiological examination. These results demonstrate that the designed models are appropriate and applicable for modeling endocardial signals coming from different parts of the heart. The research method used by the authors is the mathematical modeling using Gaussian functions approximating set elements of the endocardial signal coming from different parts of the intracardial space. The main conclusions of the research are the following: - the authors have proved that Guassian functions are applicable for the aforesaid purposes; - they have also described possible modifications of used functions for modeling signals from other endocardial spheres such as the left atrium pulmonary vein entry, mitral aortal zone and other zones  clinical electrophysiologists are particularly interested in; the authors have also demonstrated how the research results can be implemented in the form of the hardware and software complexes using the modern methodologies for assessing efficiency of treating complex heart rhythm disorders.

Abstract: The research is devoted to one of the physical nanoelectronic effect – resonant tunneling. The authors provide numerical calculations for constructing the MIS-structure based diod and modeling its characteristics. The metal-oxide-silicon semiconductor in the severe depletion mode next to the doped semiconductor has a similar structure. The authors establish the MIS-structure energy band diagram, define energy levels and wave functions of an electron in the quantum well and during tunneling and calcuate the probability of tunneling based on the amounnt of the voltage applied. In the course of calculations the authors use the PTC Mathcad Prime 3.1 visual environment for mathematical modeling and technical computing. The results of the computer modeling allow to define external limit voltage including the amount of voltage that leads to the dielectric breakdown. In addition, the authors define the qualitative dependency between the MIS-structure voltage and the height and width of the energy barrier. The model developed by the authors takes into account the joint influence of several factors which is proved by the coordination of recorded current voltrage characteristic with the experimental characteristics.

Abstract: The subject of the research is the algorithms for evaluating the information value of composite images. Composite images are formed by multispectral vision systems including multispectral enhanced vision systems used in aviation. These systems show the external space for pilots even in bad weather conditions or late at night, thus increasing operational capacities of aerial vehicles. These systems combine information incoming from physically different sensors into one composite image that is supposed to have essential information features coming from all combined video channels. The research is b ased on the computer modeling of image combination in the two-zone TV-thermal enhanced vision system using the actual images made by the visual sensors. The authors offer a new structural-semantic qualitative evaluation of the information value of composite images based on the preservation (distortion) of various information depending on their spectral energy and space characteristics. Based on the aforesaid method of evaluating the information value, the authors compare different methods of combination of images for the two-zone enhanced vision systems.

Abstract: In many sectors and state administration agencies there is a great need in the software designed for specialized calculations like a popular MATLAB system combined with the Simulink graphical programming environment, but dealing with a particular database and task descriptions and not requiring any special payment. The main disadvantage of the MATLAB+Simulink package (apart from its price) is that the Simulink library of graphical primitives is in fact limited by popular and typical engineering calculating tasks. The author of the article emphasizes the need to develop the kind of programming environment which would be based on the freely distributed software. The programming environment described by the author supports on the 'client-server' concept and bases on the Java platform and web-technologies. The client uses the visual graphics editor implemented as a browser application. The server transmits data (task configuration) to the Octave calcuation package and vice versa, calculation results are transmitted to the browser. Data is transmitted online as the JSON line. The author creates the original programming architecture for specialized mathematical calcuation systems based on the freely distributed software. Taking into account the subsystem that stores the task configuration (and needs to be developed further), this architecture becomes the basis for creating specialized systems of the decision making processes in many spheres. The architecture provides a wide range of opportunities for further development.
