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, ...

Precision Monolithics
Precision Monolithics, Inc. also known as PMI, was an American company based in Santa Clara, California, that developed and produced mixed signal and linear integrated circuits (ICs). It was a pioneer in the fields of digital-to-analog converters and operational amplifiers. The company was founded in 1969 by Marv Rudin and Garth Wilson, who had both left Fairchild Semiconductor at the end of 1968. Wilson was circuit design manager under Rudin, who managed linear circuit R&D at the Fairchild Semiconductor R&D Laboratory in Palo Alto from 1966 to 1968. At the beginning, Wilson was vice president responsible for engineering and production, and reported to Rudin, who was president and marketing manager. Jim Grugan from Fairchild joined shortly after incorporation as vice president of administration, responsible for finance, facilities and purchasing. Immediately after financing and incorporation, they offered founder stock and hired IC designers George Erdi from Fairchild and Dan Doo ...

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 requir ...

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. 76 T ...

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 ch ...

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 ...

Significant Figures
Significant figures (also known as the significant digits, ''precision'' or ''resolution'') of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something. If a number expressing the result of a measurement (e.g., length, pressure, volume, or mass) has more digits than the number of digits allowed by the measurement resolution, then only as many digits as allowed by the measurement resolution are reliable, and so only these can be significant figures. For example, if a length measurement gives 114.8 mm while the smallest interval between marks on the ruler used in the measurement is 1 mm, then the first three digits (1, 1, and 4, showing 114 mm) are certain and so they are significant figures. Digits which are uncertain but ''reliable'' are also considered significant figures. In this example, the last digit (8, which adds 0.8 mm) is also considered a significant figure even though ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
