Prognostics And Health Management
Prognostics is an engineering discipline focused on predicting the time at which a system or a component will no longer perform its intended function. This lack of performance is most often a failure beyond which the system can no longer be used to meet desired performance. The predicted time then becomes the remaining useful life (RUL), which is an important concept in decision making for contingency mitigation. Prognostics predicts the future performance of a component by assessing the extent of deviation or degradation of a system from its expected normal operating conditions. The science of prognostics is based on the analysis of failure modes, detection of early signs of wear and aging, and fault conditions. An effective prognostics solution is implemented when there is sound knowledge of the failure mechanisms that are likely to cause the degradations leading to eventual failures in the system. It is therefore necessary to have initial information on the possible failures (incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pegasus-class Hydrofoil
The ''Pegasus''-class hydrofoils were a series of fast attack patrol boats employed by the United States Navy. They were in service from 1977 until 1993. These hydrofoils carried the designation "PHM" for "Patrol Hydrofoil, Missile." The ''Pegasus''-class vessels were originally intended for NATO operations in the North Sea and Baltic Sea. Subsequently, participation by other NATO navies, including Germany and Italy, ceased and the U.S. Navy proceeded to procure six PHMs, which were highly successful in conducting coastal operations, such as narcotics interdiction and coastal patrol, in the Caribbean basin. History In the late 1960s, NATO developed a requirement for a small, fast warship to counter large numbers of Warsaw Pact missile boats, such as the and es, deciding that a hydrofoil would be the best way to meet this requirement. In 1970 Admiral Elmo Zumwalt, the new Chief of Naval Operations (CNO), keen to increase the Navy's number of surface vessels in a cost-effective ...

Hull Classification Symbol
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use. History United States Navy The U.S. Navy began to assign unique Naval Registry Identification Numbers to its ships in the 1890s. The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the battleship ''Indiana'' was USS ''Indiana'' (Battleship No. 1), the cruiser ''Olympia'' was USS ''Olympia'' (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pretty Hate Machine
''Pretty Hate Machine'' is the debut studio album by American industrial rock band Nine Inch Nails, released by TVT Records on October 20, 1989. Production of the record was handled by NIN frontman Trent Reznor and English producer Flood, among other contributors. The album features a heavily synth-driven electronic sound blended with industrial and rock elements. Much like the band's later work, the album's lyrics contain themes of angst, betrayal, and lovesickness. The record was promoted with the singles " Down in It", "Head Like a Hole", and "Sin", as well as the accompanying tour. A remastered edition was released in 2010. Although the record was successful, reaching No. 75 in the US and receiving highly favorable reviews from critics, Reznor (the band's only official member until 2016) feuded with TVT over promotion of the album, which led him to eventually sign with Interscope Records. ''Pretty Hate Machine'' was later certified triple-platinum by RIAA, becoming one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nine Inch Nails
Nine Inch Nails, commonly abbreviated as NIN and stylized as NIИ, is an American industrial rock band formed in Cleveland in 1988. Singer, songwriter, multi-instrumentalist, and producer Trent Reznor was the only permanent member of the band until his frequent collaborator, Atticus Ross, joined in 2016. The band's debut album, ''Pretty Hate Machine'' (1989), was released via TVT Records. After disagreeing with TVT about how to promote the album, the band signed with Interscope Records and released the EP ''Broken'' (1992). The following albums, ''The Downward Spiral'' (1994) and ''The Fragile'' (1999), were released to critical acclaim and commercial success. Following a hiatus, Nine Inch Nails resumed touring in 2005 and released the album ''With Teeth'' (2005). Following the release of the album ''Year Zero'' (2007), the band left Interscope after a feud. Nine Inch Nails continued touring and independently released ''Ghosts I–IV'' (2008) and ''The Slip'' (2008) before a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proto-Hmong–Mien Language
Proto-Hmong–Mien () is the reconstructed ancestor of the Hmong–Mien languages. Lower-level reconstructions include Proto-Hmongic and Proto-Mienic. The date of proto-Hmong-Mien has been estimated to be about 2500 BP by Sagart, Blench, and Sanchez-Mazas. It has been estimated to about 4243 BP by the Automated Similarity Judgment Program (ASJP), however, ASJP is not widely accepted among historical linguists as an adequate method to establish or evaluate relationships between language families. Reconstructions Reconstructions of Proto-Hmong–Mien include those of Purnell (1970), Wang & Mao (1995), Ratliff (2010), and Chen (2013), and Ostapirat (2016). Proto-Hmongic (Proto-Miao) has also been reconstructed by Wang (1994), while Proto-Mienic (Proto-Mjuenic; reconstruction excludes Biao Min and Zao Min) has been reconstructed by Luang-Thongkum (1993). Ratliff (2010) Martha Ratliff (2010) used 11 criterion languages for her reconstruction. #East Hmongic ( Qiandong); Northern ...

Pure Homopolar Motor
A pure homopolar motor (PHM) is an electric motor not requiring brushes, electronics, or semiconductor parts to convert direct current into torque. In other words, this homopolar motor only requires a theoretical homogeneous or actual (constantly or cyclically) homogenized magnetic field and direct current, similarly to the Faraday Homopolar Motor (FHM). The theory of PHM is usually explained using Maxwell's equations. In basic courses on theoretical physics you can learn that such a system should be functional and independent of brushes. This term unifies all devices that work in line with this definition. Examples include the following pure homopolar motor patents: US5977684 (A), PV2011-293 (CZ) application number 2011-293, AU5801890 (A) Another group of patents with a superconductor shield or shield made of so far unknown material (low-voltage semiconductor with high current permeability or material that excludes magnetic field A magnetic field is a ve ...
