This paper wishes to illustrate the functioning of 400/220 kV Rosiori power substation from National Power Grid – Romania, during the permanent regime and the behaviour of the electric equipment of the power substation regarding this phenomenon. According to the obtained results, we suggest that the power substation functioning of quality parameters, according to the new requirements of ENTSO – E (European Network of Transmission System Operators for Electricity. The objectives of the study: each new or upgraded power substation being the critical power infrastructure should be subject to a well-functioning risk assessment, by: simulation of different operating modes, assessment of occupational health and safety risks, assessment of security risks an assessment of reliability parameters, in the context of ensuring safety and security of electricity supply.

Today, television has emerged as the major source of entertainment and learning in our country. It has changed the lifestyle of people and become a major influence on the culture. Some students use Television and an educational tool, on the other hand, some uses it as a leisure tool. In particular, televisions impact on young people has garnered the most attention by academia and has been one area of intense study and debate. In fact, there are thousands of studies about television and its impact on young children and adolescence teenagers. For example, scholars know how many hours of television children and young students’ alike watch each day and how many television sets are in the average household. Moreover, they know where in the household these devices are located and much about children’s access to them. They know the types of programming they view and what kinds of programming different groups prefer. According to recent studies, almost every single student in the world watches television each and every day. Kinds of television programs, especially the serials, film clipping, news and news based programmes, sports and cartoons, affect people irrespective of gender, age and other demographic variables. Many people arises question as to whether television is really beneficial or does it has an actual impact on the viewer. This review article will provide us with an insight to some of the question that arises.

The article examines the state of aerospace activity, the prospects of development and directions of increasing the competitiveness of aviation, rocket and space technology in the countries of the world and Ukraine in the context of the new industrial revolution and Ukraine’s in-depth integration with the EU. It has been established that today both the aviation industry and the rocket and space complex of Ukraine need to change the priorities of development, reorganization, restructuring. There also exists the need for significant investments in order to modernise the production on the basis of advanced production technologies of the new industrial revolution (Key Enabling Technologies / Advanced Manufacturing) together with converged technologies. It is proved that considering the interests of Ukraine’s national security under conditions of increased military threat, the air-space industry may, after a certain modernisation, play a leading role in the creation of a defence shield of the state. It is recommended that the Consultative working groups of the National Academy of Sciences of Ukraine, academic institutions and independent experts should be involved in forecasting and clarifying the priorities of the development of Ukraine’s aerospace complex in the context of its integration into the world and European aerospace.

Using magnetohydrodynamic equations (MHD), we investigate plasma waves. This magnetohydrodynamic model for isothermal, gravitationally stratified plasma in a horizontal inhomogeneous magnetic field yields the dispersion equation and reflection coefficient for MHD waves. The speeds of Alfven and sound are both constant. For linearized per turbations, analytical solutions can be derived using this approach. They show the Alfven mode, as well as the fast and slow magnetoacoustic modes. Gravity has an effect on these modes. The dispersion equation describes gravito-acoustic waves in the nonmagnetized situation.

Mobile adhoc networks is a perpetual and autogenous organization without framework, and the mobile nodes are coupled cordlessly. Owing to the deficiency of framework assistance, reliable data distribution is a demanding process in mobile adhoc networks and this mobile adhoc network is unguarded to many categories of attacks. A black hole attack in Mobile Adhoc networks cites to an attack by the malevolent node which strongly get hold of the path from sender to the receiver, by means of perversion of subsequence word. With regard to diminish the menace from the malevolent node, the authors encompass the notion of trust in mobile adhoc networks. In this paper, we cope with a packet dropping misconduct named Black hole Attack and we propounded a new hybrid trust based secured algorithm hinged on four new parameters to scrutinize, whether the transitional nodes are transmitting the packets correctly to the adjacent nodes. This paper presents a new hybrid trust based concept to pinpoint the malevolent node hinged on the computation of trust value. Using ns2 simulator, we analyse the performance of our proposed method and proved the detection efficiency. The investigated results shows that our proposed work can precisely diagnose the malevolent nodes and assure a good packet delivery ratio and network throughput.
