Development of Wireless Camera Sensor Network model
This paper describes a model of wireless camera sensor network with \sloppy autonomous power sources, taking into account the specifics of such networks. We present new approach to definition of the energy efficiency in camera sensor networks based on user requirements. We also discuss the factors which influence on the image recognition process in sensor nodes and distinguish the levels of intelligence of camera sensor network.
The considered model of the failure rate of CMOS VHSIC design proposed in the article Piskun G.A., Alekseev V.F., "Improvement of mathematical models calculating of CMOS VLSIC taking into account features of impact of electrostatic discharge", published in the first issue of the journal "Technologies of electromagnetic compatibility" for the year 2016. It is shown that the authors claim that this model "...will more accurately assess the reliability of CMOS VHSIC design" is fundamentally flawed and its application will inevitably lead to inadequate results. Alternatively, the proposed model of the failure rate of CMOS VHSIC design, which also allows to take into account the views of ESD, but based on the use of resistance characteristics of CMOS VHSIC to the effects of ESD.
By analyzing the logs of corporate e-mail networks we found a number of patterns, showing how the size of ego-networks of individual employees changes on a day by day basis. We proposed a simple model that adequately describes the observed time dependence of an employee's "social circle". Comparison of experimental data with the theoretical model showed that employees are divided into two groups - with fast and slow changes in their social circles, respectively. We believe that the presence of these groups reflects both project-type and process-type of employees' activities. Comparison of data obtained before and during the global economic crisis has shown that the crisis led to an actual reduction in project-type activities.
Simulating principles of proposed attribute (A) and object-attribute (OA) architectures of computer systems (CS) that implement the dataflow execution model, and the results of a dataflow-supercomputer system simulation are described. A new formalism of "Attribute Nets" (A-nets) is proposed for mathematical modeling of dataflow-CS that differs significantly from apparatus of Petri Nets. This formalism lays foundation for the OA-programming&simulation environment of a dataflow-CS which is used in development programming and test of the OA-supercomputer system.
The given study is devoted to the issues of searching the ways for adaptation to climate change, mitigation of its impact on the economy and population, as well as to the role of increasing energy efficiency in the economies of some countries of Eastern Europe, Caucasus and Central Asia (EECCA). It also relates to the issues of responding to negative trends and emerging challenges caused by climate change. The Report represents several case studies on the above topics implemented in Moldova, Tadjikistan, Kazakhstan, Azerbaijan and the Russian Federation by the network of regional enviuronmental centres. It also contains consideration of possible methodological approaches and recommendations on addressing the above issues in the EECCA region.
The article studies the current Russian and world experience in the state policy in energy saving stimulation. The article analyses the latest changes in Russian legislation in this area. The paper underlines that a number of policy measures used abroad have not been yet implemented in Russia. The paper concludes that the study of foreign experience is extremely important as it helps to boost the transition to the energy-effective economy.
The volume contains articles of scientific staff and faculty of the Department of Computer Science and Applied Mathematics and Scientific-Educational Center of computer modeling of unique buildings and complexes of Moscow State University of Civil Engineering (National Research University), devoted to actual problems of applied mathematics and computational mechanics.
The article discusses the features of energy service contracts as one of the types of state-business interaction in the form of a publicprivate partnership. The purpose of the article is to analyze the main problems accompanying the implementation of energy service contracts on the basis of a case analysis and to develop recommendations for those who are at the stage of concluding such agreements. The following causes of problems between the parties to the energy service contracts are highlighted: methodological, organizational and financial. The following recommendations are developed based on the experience of participation in forensic examinations:1) careful study of the methodology for calculating savings using energy audit;2) the method of calculating the economic effect should be an integral part of the energy service contract;3)careful management of documents in order to be able to begin to resolve the conflict in the pretrial order according to the Civil Code;4) the contractor must make sure that there are economic benefits based on detailed calculations of indicators such as payback period, net present value of the project, internal rate of return, which it is mandatory to compare with the cost of financial resources used in the project.
