Abstract Modern electronics systems consist of not only with the power electronics converters, but also with the friendly user interface which allow you to read the operating parameters and change them. The simplest solution of the user interface is to use alphanumeric display which displays information about the state of the converter. With a few additional buttons you can change the settings. This solution is simple, inexpensive but allows only local control (within walking distance from the system) and the number of displayed information is low. You can create extensive menu, but it causes problems with access to information. This paper presents the example of a rotating energy storage universal solution which is lack of the above mentioned disadvantages

The Media

We have designed, implemented, and deployed a camera control system and a conference controller that provide remote control capabilities for videoconferencing over the Internet. The camera control system allows users to pan, tilt, and zoom the cameras, switch between cameras, and get a picture-in-picture view from their desktops. The conference controller allows conference participants to not only start and stop the media tools on a remote host, but also to dynamically change settings and turn transmission on and off. It supports the vic (video) and vat (audio) Internet videoconferencing tools and enhances their usability by providing an integrated and secure user interface for local and remote control of these applications. This paper describes the design and implementation of the camera control system (devserv and camclnt) and the conference controller (confcntlr). The remote control capabilities offered by these tools have changed the videoconferencing paradigm to one of telepresence. With these tools remote users can “walk” around the room, focus in on objects, and actively participate rather than just observe.

In this project, a system was designed for charging batteries in electric vehicles using photovoltaic panels. Low cost of operation, cheap construction and simple user interface were among the main criteria taken into account. Each energy source was carefully selected and modules were used so that they could power the microcontroller and charge the energy storage source. The solution was patented [1]. This article is a part of a project related to the design of digital control devices with electric drives carried out at the UWM. The control system solutions developed at UWM have been published in the book {15}.

The internet service is provided by a given number of servers located in the main node of internet service provider (ISP). In some cases; the overload problem was occurred because a demand on a given website goes to very high level. In this paper, a fuzzy logic control (FLC) has proposed to distribute the load into the internet servers by a smart and flexible manner. Three effected parameters are tacked into account as input for FLC: link capacity which has three linguistic variables with Gaussian membership function (MF): (small, medium and big), traffic density with linguistic variables (low, normal and high) and channel latency with linguistic variables (empty, half and full); with one output which is the share server status (single, simple and share). The proposed work has been simulated by using MATLAB 2016a, by building a structure in the Fuzzy toolbox. The results were fixed by two manners: the graphical curves and the numerical tables, the surface response was smoothly changed and translates the well-fixed control system. The numerical results of the control system satisfy the idea of the smart rout for the incoming traffics from the users to internet servers. So, the response of the proposed system for the share of server ratio is 0.122, when the input parameter in the smallest levels; and the ratio is 0.879 when the input parameters are in highest level. The smart work and flexible use for the FLC is the main success solution for most of today systems control.

The Right

The study of law focuses, among other aspects, on important issues relating to equality, fairness and justice in as far as free access to information and knowledgeis concerned. The launching of the Open Access to Law Movement in 1992, the promulgation of the Durham Statement on Open Access to Legal Scholarshipin 2009, and the formation of national and regional Legal Information Institutes (LIIs) should serve as an indication of how well the legal world is committed to freely publishing and distributing legal information and knowledge through the Internet to legal practitioners, legal scholars and the public at large aroundthe world. In order to establish the amount of legal scholarly content which is accessible through open access publishing innovations and initiatives, this studyanalysed the contents of websites for selected open access resources on the Internet internationally and in South Africa. The results of the study showed that there has been a steady developing trend towards the adoption of open access for legal scholarly literature internationally, while in South Africa legal scholarly literature is under the control of commercial publishers. This should be an issue for the legal scholarship which, among its focus, is to impart knowledge about the right of access to information and knowledge.

Public Demand

At times of crisis, access to information takes on special importance, and in the Internet age of constant connectedness, this is truer than ever. Over the course of the pandemic, the huge public demand for constantly updated health information has been met with a massive response from official and scientific sources, as well as from the mainstream media. However, it has also generated a vast stream of user-generated digital postings. Such phenomena are often regarded as unhelpful or even dangerous since they unwittingly spread misinformation or make it easier for potentially harmful disinformation to circulate. However, little is known about the dynamics of such forums or how scientific issues are represented there. To address this knowledge gap, this chapter uses a corpus-assisted discourse approach to examine how “expert” knowledge and other sources of authority are represented and contested in a corpus of 10,880 reader comments responding to Mail Online articles on the development of the COVID-19 vaccine in February–July 2020. The results show how “expert” knowledge is increasingly problematized and politicized, while other strategies are used to claim authority. The implications of these findings are discussed in the context of sociological theories, and some tentative solutions are proposed.

Overall Reliability

An ‘ideal* converter would accept the power flow of a 3-phase a.c. system operating with sinusoidal voltage and current, and, without energy storage and by a continuous process, convert to or from d.c. Present-day converters rely, however, on repetitive circuit switching operations, more than 12 per cycle being generally uneconomic despite the cost of the energy storage components required in damping circuits and in the filters to maintain acceptable waveforms. Analysis of the operation of such converters is based on the mathematics of repetitive transients (Laplace and Fourier) and on the use of a d.c. transmission simulator, an extensive model at 10 -7 scale in power, which is also necessary in the development of complex electronic control circuits. There exists a great background of experience contributing to the design of most components of the power circuit. In contrast, the development of the switching device, whether thyristor stack or mercury arc valve, calls for advances in the state of art, both in scientific appreciation and in technology, which must be supported by full scale tests. There is little immediate prospect of the theoretical ‘ ideal * converter, but this is unimportant, provided that development leads to enhanced overall reliability.

The intelligent lighting control system is one of typical applications of the Internet of things. The method of intelligent lighting control system based on industrial wireless technology is proposed in the paper. It used proposed three-point-control technology, and adjusting the brightness of lamps, turn on/off the lamps and a part of fault detection can be realized. At the same time, it can greatly reduce the cost of system. It will be useful to engineer and researchers.
