Fender Precision Bass
The Fender Precision Bass (often shortened to "P-Bass") is a model of electric bass guitar manufactured by Fender Musical Instruments Corporation. In its standard, post-1957 configuration, the Precision Bass is a solid body, four-stringed instrument usually equipped with a single split-coil humbucking pickup and a one-piece, 20-fret maple neck with rosewood or maple fingerboard. Its prototype, designed by Leo Fender in 1950, was brought to market in 1951. It was the first electric bass guitar to earn widespread attention and use, remaining among the best-selling and most-imitated electric bass guitars with considerable effect on the sound of popular music. Background The double bass is among the largest and most physically cumbersome instruments which are regularly still transported by the player themselves on their own. It is also hard to hear in large bands or those that use amplified instruments, and it requires specialized skills to play that are distinct from those re ...

Precisionism
Precisionism was a modernist art movement that emerged in the United States after World War I. Influenced by Cubism, Purism, and Futurism, Precisionist artists reduced subjects to their essential geometric shapes, eliminated detail, and often used planes of light to create a sense of crisp focus and suggest the sleekness and sheen of machine forms. At the height of its popularity during the 1920s and early 1930s, Precisionism celebrated the new American landscape of skyscrapers, bridges, and factories in a form that has also been called "Cubist-Realism." The term "Precisionism" was first coined in the mid-1920s, possibly by Museum of Modern Art director Alfred H. Barr although according to Amy Dempsey the term "Precisionism" was coined by Charles Sheeler. Painters working in this style were also known as the "Immaculates", which was the more commonly used term at the time. The stiffness of both art-historical labels suggests the difficulties contemporary critics had in attemptin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precision Club
Precision Club is a bidding system in the game of contract bridge. It is a strong club system developed in 1969 for C. C. Wei by Alan Truscott, and used by Taiwan teams in 1969. Their success in placing second at the 1969 Bermuda Bowl (and Wei's multimillion-dollar publicity campaign) launched the system's popularity. The central feature of the Precision system is that an opening bid of one club is used for any hand with 16 or more high card points (HCP), regardless of distribution. An opening bid of one of a major suit signifies a five-card suit and 11–15 HCP. A one notrump opening bid signifies a balanced hand (no five-card major suit) and 13–15 HCP. Popularity After the success of Taiwan teams in 1969 and 1970 Bermuda Bowls with the system, the entire Italian Blue team switched to Precision Club and won yet another World Team Olympiad in 1972. The modifications to the system were made chiefly by Benito Garozzo and he titled it Super Precision. Today, multiple world cham ...

Precision Drilling
Precision Drilling Corporation is the largest drilling rig contractor in Canada, also providing oil field rental and supplies. History Precision Drilling Ltd. was founded in 1951. In 1987, Precision Drilling was acquired by Cypress Drilling, led by president Hank Swartout, in a reverse takeover which left the company with a fleet of 19 rigs. Swartout led the company through extensive growth until his retirement in 2007. In 2005, Precision sold its energy services and international contract-drilling divisions to Weatherford International for $2.28 billion and reorganized as an income trust. Precision converted from an income trust back to a corporation in 2010. In 2008, Precision acquired its US rival Grey Wolf Inc. for $2 billion, a merger which expanded its rig count in the US, which it had largely left in 2005, over tenfold. The acquisition led to financial difficulties which led to a $330M CAD investment by the Alberta Investment Management Corporation (AIMCo) in 2009, ch ...

Precision And Recall
In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space. Precision (also called positive predictive value) is the fraction of relevant instances among the retrieved instances, while recall (also known as sensitivity) is the fraction of relevant instances that were retrieved. Both precision and recall are therefore based on relevance. Consider a computer program for recognizing dogs (the relevant element) in a digital photograph. Upon processing a picture which contains ten cats and twelve dogs, the program identifies eight dogs. Of the eight elements identified as dogs, only five actually are dogs (true positives), while the other three are cats (false positives). Seven dogs were missed (false negatives), and seven cats were correctly excluded (true negatives). The program's precision is then 5/8 (true positives / sel ...

Precision (march)
''Precision'' is the authorized march of Royal Military College of Canada. The RMC band performs Precision during parades and march pasts, as well as on Ex-Cadet Weekends. History Precision was composed in 1932 by Denise Chabot, wife of Major C. A. Chabot, a Royal Canadian Artillery officer on staff as professor of French at the College at the time. She earned the degree of Associate of the Royal Conservatory of Music and was the president of the Kingston Music Club. ''Precision'' was inspired by "Madelon", one of the popular marching songs sung and whistled by the cadets marching on their way to the Riding School, and the favourite song of the Class of 1932. Mme Chabot improvised a variation on the song, to represent the cadence of the cadets on the march. The composition starts, “We are the gentlemen cadets of RMC We have sworn to love and serve Her Majesty…” Source: Royal Military College of Canada – Review Yearbook (Kingston, Ontario Canada) – Class of 1942 pg. 7 ...

Accuracy And Precision
Accuracy and precision are two measures of '' observational error''. ''Accuracy'' is how close a given set of measurements (observations or readings) are to their '' true value'', while ''precision'' is how close the measurements are to each other. In other words, ''precision'' is a description of '' random errors'', a measure of statistical variability. ''Accuracy'' has two definitions: # More commonly, it is a description of only ''systematic errors'', a measure of statistical bias of a given measure of central tendency; low accuracy causes a difference between a result and a true value; ISO calls this ''trueness''. # Alternatively, ISO defines accuracy as describing a combination of both types of observational error (random and systematic), so high accuracy requires both high precision and high trueness. In the first, more common definition of "accuracy" above, the concept is independent of "precision", so a particular set of data can be said to be accurate, precise, both ...

PA-RISC
PA-RISC is an instruction set architecture (ISA) developed by Hewlett-Packard. As the name implies, it is a reduced instruction set computer (RISC) architecture, where the PA stands for Precision Architecture. The design is also referred to as HP/PA for Hewlett Packard Precision Architecture. The architecture was introduced on 26 February 1986, when the HP 3000 Series 930 and HP 9000 Model 840 computers were launched featuring the first implementation, the TS1. PA-RISC has been succeeded by the Itanium (originally IA-64) ISA, jointly developed by HP and Intel. HP stopped selling PA-RISC-based HP 9000 systems at the end of 2008 but supported servers running PA-RISC chips until 2013. History In the late 1980s, HP was building four series of computers, all based on CISC CPUs. One line was the IBM PC compatible Intel i286-based Vectra Series, started in 1986. All others were non-Intel systems. One of them was the HP Series 300 of Motorola 68000-based workstations, another ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
