Deception and media manipulation have always been an integral part of wartime propaganda. But never before has it been so easy to create high-quality fabrications of images as well as sound and video recordings. The tendency to react emotionally to these media opens up a whole new possibility...

Täuschung und Medienmanipulation sind seit jeher fester Bestandteil der Kriegskommunikation. Nie zuvor aber war es derart einfach, qualitativ hochwertige Fäl­schungen von Ton-, Bild- und Videoaufzeichnungen zu erstellen. Die menschliche Neigung, emotional auf diese Medien zu reagieren,...

Deception and media manipulation have always been an integral part of wartime propaganda. But never before has it been so easy to create high-quality fabrications of images as well as sound and video recordings. The tendency to react emotionally to these media opens up a whole new possibility...

This paper focuses on the electro-thermal analysis of a doubly-fed induction generator (DFIG) in a wind turbine (WT) with gear transmission configuration. The study of the thermal mechanism plays an important role in the development of cost-effective fault diagnostic techniques, design for...

Base station sites (BSSs) powered with renewable energy sources have gained the attention of cellular operators during the last few years. This is because such “green” BSSs impose significant reductions in the operational expenditures (OPEX) of telecom operators due to the possibility of...

Research in marine current energy, including tidal and ocean currents, has undergone significant growth in the past decade. The horizontal-axis marine current turbine is one of the machines used to harness marine current energy, which appears to be the most technologically and economically...

Off grid telecom base stations in developing nations are powered by diesel generators. They are typically oversized and run at a fraction of their rated load for most of their operating lifetime. Running generators at partial load is inefficient and, over time, physically damages the engine. A...

This article describes how a drastic failure of a machine is caused by insulation collapse which results heavy interruption as well as losses. The stable operation of a generator mainly depends upon the stator winding insulation. In past, various testing and repairing techniques have been...

Urban litter is generated by human societies everywhere. Some litter is recyclable waste. In this study, the acronym RMSW is used to refer to recyclable municipal solid waste generated in streets. Public attitude towards RMSW generation, generators’ perceptions, and quantification of RMSW in...

This paper attempts to identify the underlying causes and costs of own generation of electric power in Africa. Rigorous empirical analysis of 8483 currently operating firms in 25 African countries shows that the prevalence of own generation would remain high (at around 20%) even if power...

A wind farm for the deployment of pumping mode AWE (airborne wind energy) systems is presented in this paper. The topology presented is suitable for the deployment of such systems in a marine or similarly inaccessible environment. A brief technical description of AWE is provided, outlining the...

Convergence of a sequence of bivariate Archimedean copulas to another Archimedean copula or to the comonotone copula is shown to be equivalent with convergence of the corresponding sequence of Kendall distribution functions.No extra differentiability conditions on the generators are needed.

This paper is an evaluation of the employment role of Cart Pushing in Metropolitan Lagos and how it sustains the operators and by extension family members. Currently, Lagos accommodates 65% of industries in Nigeria, which account for the attraction of people from every part of Nigeria in search...

The efficiency of micro gas turbine generator is affected significantly by the temperature level in the micro gas turbine system. If the operation temperature of generator and compressor increases, the efficiency of generator and compressor decreases, greatly. This study investigates the heat...

The purpose of this paper is to provide an analytical review of wind turbine-generator systems for stand-alone applications. The review focuses on variable-speed wind turbines, as the future trend in wind energy conversion, in contrast with the traditional fixed-speed wind turbines....

A vertical axis wind turbine has been designed to electrify a novel kind of telecommunication tower. This paper presents the design of a generator for this purpose. The generator is a permanent magnet generator rated at 10 kW. It has an unusually large diameter to fit on the outside of the...

The wind farm generators are new energies sources in the Algerian electrical networks, as every project their placements are determined by the wind assets of the site suitability (economic evaluation), its proximity to the power grid of which it will be connected (technical assessments). The...

The non-uniformity of the air temperatures and the slow flow rate at the plane collector exit constitute the main cause of the limitations of the solar drying systems. In order to obtain an uniform and a variable flow rate for different uses, a hot air generator using concentrated solar...

The performance of an MHD generator utilizing plasma as working fluid has been assessed from the viewpoint of the second law of thermodynamics. The plasma flow in the generator linear duct has been solved by dividing the channel cross-section to an inviscid core region and the viscous boundary...

Bei der Nutzung von Umwelt und Natur konkurriert die heutige Generation mit zukünftigen Generationen. Mineralische Brennstoffe wie Erdöl, die wir heute verwenden, sind in der Zukunft nicht mehr vorhanden, metallische Rohstoffe lediglich durch die Wiederverwendung teilweise zurückgewinnbar....

The development of the competitive electricity supply market in the United Kingdom and government support for renewable energy technologies is discussed. Non-Pooled trading in renewable electricity is described and economic comparisons are made of electricity prices. Experiences in the new...
