Laboratory For Energy Conversion
The Laboratory for Energy Conversion (LEC) formerly known as Turbomachinery Laboratory (LSM) was founded in 1892 by Aurel Boleslav Stodola. As part of the Federal Institute of Technology Zurich (ETH). The laboratory has been headed by some of the most prominent mechanical engineers in the history of turbomachinery. Areas of research The current research projects at LEC cover the fields of: * energy economics and policy * performance and reliability of wind energy * minimizing high-cycle fatigue failure of compressors * efficiency improvements of turbomachines * aircraft noise suppression * cooling and thermal management * laser produced plasma source ( EUV) and debris mitigation * development of a mobile power pack * novel measurement techniques * biomedical diagnostics Awards Amongst many noted achievements, LEC has recently developed the FENT probe. This probe, for the first time, enables measurement of entropy generation in Turbomachinery. The highly rated peer-revie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public University
A public university or public college is a university or college that is in state ownership, owned by the state or receives significant government spending, public funds through a national or subnational government, as opposed to a private university. Whether a national university is considered public varies from one country (or region) to another, largely depending on the specific education landscape. Africa Egypt In Egypt, Al-Azhar University was founded in 970 AD as a madrasa; it formally became a public university in 1961 and is one of the oldest institutions of higher education in the world. In the 20th century, Egypt opened many other public universities with government-subsidized tuition fees, including Cairo University in 1908, Alexandria University in 1912, Assiut University in 1928, Ain Shams University in 1957, Helwan University in 1959, Beni-Suef University in 1963, Zagazig University in 1974, Benha University in 1976, and Suez Canal University in 1989.

Entropy
Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory. It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change, and information systems including the transmission of information in telecommunication. The thermodynamic concept was referred to by Scottish scientist and engineer William Rankine in 1850 with the names ''thermodynamic function'' and ''heat-potential''. In 1865, German physicist Rudolf Clausius, one of the leading founders of the field of thermodynamics, defined it as the quotient of an infinitesimal amount ...

MTU Aero Engines
MTU Aero Engines AG is a German aircraft engine manufacturer. MTU develops, manufactures and provides service support for military and civil aircraft engines. MTU Aero Engines was formerly known as MTU München. History While the Munich-based engine manufacturer Rapp Motorenwerke, and subsequently BMW, had produced aircraft engines since 1913, the modern company regards the formal date of its formation as being 1934, the year in which ''BMW Flugmotorenbau GmbH'' was spun-off from BMW. This step was initiated by the Ministry of Aviation in order to disguise the planned rearmament of the Luftwaffe – as a standalone limited company the ''Flugmotorenbau GmbH'' had less strict disclosure requirements. Additionally, BMW aimed at outsourcing the unforeseeable risk of contributing to the German rearmament. In 1936, BMW built an aircraft engine plant in Allach near Munich, which are the headquarters of MTU Aero Engines today. In 1940, the plant was expanded significantly to start la ...
