Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after the commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, Electromagnetism, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control ...

Sagnac Effect
The Sagnac effect, also called Sagnac interference, named after French physicist Georges Sagnac, is a phenomenon encountered in interferometry that is elicited by rotation. The Sagnac effect manifests itself in a setup called a ring interferometer or Sagnac interferometer. A beam of light is split and the two beams are made to follow the same path but in opposite directions. On return to the point of entry the two light beams are allowed to exit the ring and undergo interference. The relative phases of the two exiting beams, and thus the position of the interference fringes, are shifted according to the angular velocity of the apparatus. In other words, when the interferometer is at rest with respect to a nonrotating frame, the light takes the same amount of time to traverse the ring in either direction. However, when the interferometer system is spun, one beam of light has a longer path to travel than the other in order to complete one circuit of the mechanical frame, and so take ...

Stanford University Alumni
Leland Stanford Junior University, commonly referred to as Stanford University, is a private research university in Stanford, California, United States. It was founded in 1885 by railroad magnate Leland Stanford (the eighth governor of and then-incumbent United States senator representing California) and his wife, Jane, in memory of their only child, Leland Jr. The university admitted its first students in 1891, opening as a coeducational and non-denominational institution. It struggled financially after Leland died in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, university provost Frederick Terman inspired an entrepreneurial culture to build a self-sufficient local industry (later Silicon Valley). In 1951, Stanford Research Park was established in Palo Alto as the world's first university research park. By 2021, the university had 2,288 tenure-line faculty, senior fellows, center fellows, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharif University Of Technology Alumni
Sharīf or Sherif (, 'noble', 'highborn'), also spelled shareef, feminine sharīfa (), plural ashrāf (), shurafāʾ (), or (in the Maghreb) shurfāʾ, is a title used to designate a person descended, or claiming to be descended, from the family of the Islamic prophet Muhammad ( ). It may be used in three senses: #In the broadest sense, it refers to any descendant of Muhammad's great-grandfather Hashim (the Banu Hashim or Hashimites, already in Muhammad's day an established clan within the Meccan tribe of the Quraysh), including all descendants of Muhammad's paternal uncles Abu Talib (the Talibids) and al-Abbas (the Abbasids).. #More often, it refers to a descendant of Ali, a son of Abu Talib and a paternal cousin of Muhammad (the Alids), especially but not exclusively through Ali's marriage with Muhammad's daughter Fatima (the Fatimids). In the sense of descendants of Fatima and Ali (the most common one), the term effectively refers to all descendants of Muhammad. #In th ...

International Physics Olympiad
The International Physics Olympiad (IPhO) is an annual physics competition for high school students. It is one of the International Science Olympiads. The first IPhO was held in Warsaw, Poland in 1967. Each national delegation is made up of at most five student competitors plus two leaders, selected on a national level. Observers may also accompany a national team. The students compete as individuals, and must sit for intensive theoretical and laboratory examinations. For their efforts the students can be awarded gold, silver, or bronze medals or an honourable mention. The theoretical examination lasts 5 hours and consists of three questions. Usually these questions involve more than one part. The practical examination may consist of one laboratory examination of five hours, or two, which together take up the full five hours. History The idea of creating the International Physics Olympiad was conceived in Eastern Bloc countries, inspired by the 1959 established Inter ...

International Solid-State Circuits Conference
International Solid-State Circuits Conference is a global forum for presentation of advances in solid-state circuits and Systems-on-a-Chip. The conference is held every year in February at the San Francisco Marriott Marquis in downtown San Francisco. ISSCC is sponsored by IEEE Solid-State Circuits Society. According to ''The Register'', "The ISSCC event is the second event of each new year, following the Consumer Electronics Show, where new PC processors and sundry other computing gadgets are brought to market." History of ISSCC Early participants in the inaugural conference in 1954 belonged to the Institute of Radio Engineers (IRE) Circuit Theory Group and the IRE subcommittee of Transistor Circuits. The conference was held in Philadelphia and local chapters of IRE and American Institute of Electrical Engineers (AIEE) were in attendance.
