Mobile ad-hoc network is a kind of network which is infrastructure-less and can be designed for fulfilling particular purpose that is served by the establishment of the whole setup on the fly. In this research, we have analysed the detection of black hole attack with prevention solution to black hole attacks on AODV protocol. As mobile nodes send data packets using intermediate nodes and due to week security mechanism, MANET suffers from many intruders attacks. Black Hole attack is a denial of service attack and when a malicious node sends RREP to source node to show its fresh and shortest path to destination and after receiving data packets, drop them or share with another malicious node instead of uncompromised for-warding to destination node. In this study, an approach is proposed for the detection and prevention of black hole attack and making the path secure from malicious node involvement by using Honey-Pot technique and keeping secure the network by broadcasting malicious node address to other nodes in network.


The professional identification of Russian youngers today is largely determined not only by the desire of young people to get one or another profession, but also by their desire to get a professional education that will enable them to receive a higher level of income in the future. That means that the process of professional orientation and professional identification of youth might be managed by the State Educational Policy. The purpose of this management process is the formation of an effective, competitive labor force that allows to reduce the structural unemployment on national labor market.The data of the research is the official statistics, as well as the results of all-Russian author's monitoring research for the period 2001-2017. The research, that we got, shows that the higher education attitudes of Russian youngers, have changed alot.We use the modeling approach to define the features of the modern sector of Higher Education. The social and economical modeling of the higher education system can reveal the main correlation factors of younger’s demand for the higher education programs what will help us to find out the main streams of further professions, training directions, educational technologies development.The results also will allow us to determine the directions for the further development of the system of higher professional education in Russia, to identify competitive areas of education, training areas, and training technologies.

Removal of Diesel Soot Particles by Cyclone and Hydro Cyclone[]

Diesel exhaust is composed of two phases; either gas or particle and both phases contribute to the risk. The reduction of particulate emissions from diesel engine is one of the most challenging problems in modern society. As a special report on global exposure to air pollution and its disease burden 2017, Exposure to PM2.5 the leading environmental risk factor for death, accounting for about 4.2 million deaths ranks 5th worldwide among all risks, including smoking, diet, and high blood pressure.The main particulate fraction of diesel exhaust consists of ultra fine particles. The research aims to reduce the emissions of diesel soot particles from diesel electrical generator using Cyclone and Hydro Cyclone. The Cyclone separator designed as Salcedo model achieved about 8% of soot removal efficiency from a total soot mass concentration (1.2 g/m3). Hydro Cyclone designed by Combine Salcedo Cyclone with Venturi constriction, wherein the exhaust gas stream is contacted with higly pressure liquid stream at least 140 bar to produce a substantially liquid saturated exhaust gas stream. Wet Filtration remove about 90% of soot particles mass in the flow rate of spray water to exhaust gas (0.62 l/m3) below the universally recommended values (1.7 - 0.67 liter water / m3).
