Abstract The simple digital filters are not sufficient for digital modeling of systems with distributed parameters. It is necessary to apply more complex digital filters. In this work, a set of filters, called the digital function filters, is proposed. It consists of digital filters, which are obtained from causal and stable filters through some function transformation. In this paper, for several basic functions: exponential, logarithm, square root and the real power of input filter, the recursive algorithms of the digital function filters have been determined The digital function filters of exponential type can be obtained from direct recursive formulas. Whereas, the other function filters, such as the logarithm, the square root and the real power, require using the implicit recursive formulas. Some applications of the digital function filters for the analysis and synthesis of systems with lumped and distributed parameters (a long line, phase shifters, infinite ladder circuits) are given as well.

The Current and future leaders live in a turbulent and chaotic environment, where the real power of acting derives from the recognition of the concept of change and looking for options. In this type of environment a lot of competence is necessary for the leaders to survive. The aim of this study case was to explore i.e. gain a clearer picture of the position of the leader, their characteristics, functions, levels, the core and the factors affecting the leader and their leadership. To see what type of leader the people want simply to draw conclusions about the characteristics, qualities and techniques of a leader and their leadership. So that in the end, to have empirical proof of the leader. The set goal in this study case is today’s leaders in everyday process, starting from the very beginning of their work, to serve as an example in developing inter-personal skills at the same time as treating people with dignity and respect. In other words, they have to possess leadership skills, characteristics and the necessary actions. This research aims at finding out the real attributes that is the profile of a leader and their leadership running an organization regardless if it is economic, political, and military or some other non-governmental organization. The values are more than a set of rules, they are not only behavior code, and they say what a leader should be every day in every action that they take. The values shade the leaders’ identity and the organization that they run.

This paper proposes Enhanced Frog Leaping Algorithm (EFLA) to solve the optimal reactive power problem. Frog leaping algorithm (FLA) replicates the procedure of frogs passing though the wetland and foraging deeds. Set of virtual frogs alienated into numerous groups known as “memeplexes”. Frog’s position’s turn out to be closer in every memeplex after few optimization runs and certainly, this crisis direct to premature convergence. In the proposed Enhanced Frog Leaping Algorithm (EFLA) the most excellent frog information is used to augment the local search in each memeplex and initiate to the exploration bound acceleration. To advance the speed of convergence two acceleration factors are introduced in the exploration plan formulation. Proposed Enhanced Frog Leaping Algorithm (EFLA) has been tested in standard IEEE 14,300 bus test system and simulation results show the projected algorithm reduced the real power loss considerably.

AbstractA multi-terminal voltage-source-converter (VSC) based high voltage direct current (HVDC) system is concerned for its flexibility and reliability. In this study, a control strategy for multiple VSCs is proposed to auto-share the real power variation without changing control mode, which is based on “dc voltage droop” power regulation functions. With the proposed power regulation design, the multiple VSCs automatically share the real power change and the VSC-HVDC system is stable even under loss of any one converter while there is no overloading for any individual converter. Simulation results show that it is effective to balance real power for power disturbance and thus improves operation reliability for the multi-terminal VSC-HVDC system by the proposed control strategy.

In this paper Enhanced Spider (ES) algorithm is proposed to solve reactive power Problem. Enthused by the spiders, a new Enhanced Spider (ES) algorithm is utilized to solve reactive power problem. The composition is primarily based on the foraging approach of social spiders, which make use of of the vibrations spread over the spider web to choose the position of prey. The simulation results demonstrate high-quality performance of Enhanced Spider (ES) algorithm in solving reactive power problem.  The projected Enhanced Spider (ES) algorithm has been tested in standard IEEE 57,118 bus systems and compared to other reported standard algorithms. Results show that Enhanced Spider (ES) algorithm is more efficient than other algorithms in reducing the real power loss.

The Russo-Georgia war in 2008 and the conflict in Ukraine in 2014 galvanized the countries, which are namely squeezed between NATO and Russia into considering their strategies again. The paper examines Russia’s efforts to maintain its influence in its “near abroad” in the face of NATO’s enlargement. It principally focuses on identifying the challenges particular countries face as obstacles to NATO accession. The arguments raised in the paper prove that, the primary reasons of Russia-Georgia War and Ukraine conflict are associated with these countries’ NATO aspiration. An argument regarding the Alliance’s reluctance to actively engage in partner nations is also presented. The objective of the study is to consider the repercussions of NATO aspiration and introduce the real prospects of cooperation with NATO. The research methods primarily used in the book are comparative analysis and synthesis.

The creative and cultural sectors in the United Kingdom largely exclude the working classes. Even the small number of working-class people who do ‘make it’ into these sectors often find themselves and their work badly treated by those who hold the real power. This article explores some of the experiences of working-class artists navigating the cultural sector and how exclusion, prejudice and precarity impacted and continue to impact them. It takes as its focus the filmmaker Alan Clarke and the playwright Andrea Dunbar, who were at the height of their success in the 1980s. It also considers the writers Darren McGarvey and Nathalie Olah, whose work has achieved prominence in recent years. It is through this focus I hope to demonstrate the long continuum of challenges for working-class creatives. This article also considers how, on the occasions when they are allowed the space they deserve, working-class artists have created powerful shifts in cultural production. Finally, it details some of the changes needed for working-class people to be able to take their rightful place in contributing to cultural life and the societal risks involved if they are denied that place.

The Mass Media

During the last years the mass media have paid less and less attention to parliamentary activities. That is so because the real decision making, the real power, has shifted from the legislature to the executive. There are also other reasons for the declining interest in parliament: its complicated functioning, the limited interest of parliament in topical subjects, the often lengthy and technical debates.  Parliament and mass media could, however, try to bridge the gap between eachother, e.g. by broadcasting special programmes on parliamentary activities.  This might give the parliament a chance to reconquer a portion of its lost power.  However, it remains to be proved that there is a genuine political willingness to restore the legislature as the dominant political power centre. The mass media cannot and may not be a party to this conflict. They can only be a tool.

The Erotic

The article considers the erotic genre of traditional Chinese art, chun gong hua (‘spring palace paintings’), which was developed in painting. The study uses comparative - historical, cultural and historical methods, as well as methods of systematization, analysis and synthesis. The author traces the formation and evolution of the genre, reveals its specific features. The paper analyzes the system of artistic images of the works of chun gong hua, reveals that they are based on the ideas of Taoism, which are visualized through painting, which made it possible to reveal a second, meaningful plan of paintings filled with metaphors and allegories. Particular attention is paid to the characterization of expressive means, specific techniques and visual techniques of the genre. The study shows that due to the richness of images, artistic and expressive means and techniques, juxtaposition of the conditional and the real, double transformation of nature, the first impression of seemingly pornographic images of naked bodies and erotic scenes is subdued. The high artistry of the ‘spring palace paintings’ allows us to attribute them to the unique works of Chinese traditional art.
