Double check - Wikipedia, the free encyclopedia The only replies to a double check are king moves, as capturing the checking piece (except by the king, which in the process moves out of check-by-the-other-piece) is not an option since there are two of them, and interposition is likewise impossible as there would be two lines of attack to block. The most common form of one check involves one piece moving to deliver check, at the same time revealing a discovered check from a piece behind (such a check is an inherent part of the type of smothered mate known as Philidor's legacy). In chess, a double check is a check delivered by two pieces at the same time. en.wikipedia.org /wiki/Double_check   (316 words)

Check valve - Wikipedia, the free encyclopedia A double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines. A clapper valve is a type of check valve used in or with firefighting, and has a hinged gate (often with a spring urging it shut) that will only remain open in the outflowing direction. A check valve is a mechanical device, a valve, that normally allows fluid or gas to flow through it in only one direction. en.wikipedia.org /wiki/Check_valve   (200 words)

Check kiting - Wikipedia, the free encyclopedia Check kiting is any sort of fraud that involves drawing out money from one bank account that does not have sufficient funds to cover the check. Check kiters typically write a check on one account, then deposit into their second bank account (this type of check is referred to as a kite). Check kiting is one of the many bank frauds perpetrated by Frank Abagnale, who wrote a book about his escapades, which was later made into a movie called Catch Me If You Can. en.wikipedia.org /wiki/Check_kiting   (294 words)

Discovered attack - Wikipedia, the free encyclopedia The discovered check is a subset of this, where the unmasked attack is a check (conceivably, the piece moving away can also give check; in that case a double check results). Discovered attacks in general, and discovered checks in particular, can be extremely powerful, as the piece moved can make a threat independently of the piece it reveals. This scenario is often referred to as a discovered check (or attack) with capture. en.wikipedia.org /wiki/Discovered_attack   (294 words)

Reality Check 2000 Reality Check is conducted in association with Education Week and funded by the Pew Charitable Trusts and the GE Fund. Reality Check shows that few parents have a solid base of information about how well their child or their child's school performs compared with others, but parents who are familiar with school report cards are much more knowledgeable. Reality Check suggests that many schools have either not adopted some changes advocated by reformers, or that many teachers, parents, and students are unaware of them. www.publicagenda.org /specials/rc2000/reality.htm   (598 words)

Check-raise - Wikipedia, the free encyclopedia A check-raise in poker is a common deceptive play in which a player checks early in a betting round, hoping someone else will open. The player who checked then raises in the same round. This might be done, for example, when the first player believes that an opponent has an inferior hand and will not call a direct bet, but that he may attempt to bluff, allowing the first player to win more money than he would by betting straightforwardly. en.wikipedia.org /wiki/Check-raise_(poker)   (171 words)

Rain check - Wikipedia, the free encyclopedia The former is particularly useful if the merchant was having a sale on the item, as the customer can return later and use the rain check to purchase the item at the sale price even if the item is no longer on sale. Others argue that the origin of the term comes from American baseball - early stadiums were often roofless, and in the event of rain the stadium managers would distribute raincheck slips which allowed ticket holders to watch the game at a later date without purchasing an additional ticket. The term is also used in social interactions - "I'll have to get a raincheck on that" is a polite way to turn down an invitation to a party, a date, or a social get-together. en.wikipedia.org /wiki/Rain_check   (208 words)

Parity checks The idea of a parity check is to make an extremely primitive message digest. To find out the parity of a message, we add up the bits in the message; if the number of 1's is even, then we say that the message has even parity (or parity zero). If the number of 1's is odd, then we say that the message has odd parity, (or parity 1). www.iu.hio.no /data/QIC/info2/node8.html   (208 words)

Chess - Wikipedia, the free encyclopedia In chess, when a king is directly attacked by one or more of the opponent's pieces, the player is said to be in 'check'. Chess is sometimes seen as an abstract wargame; as a "mental martial art", and teaching chess has been advocated as a way of enhancing mental prowess. Chess is one of the world's most popular games; it has been described not only as a game, but also as an art, science, and sport. en.wikipedia.org /wiki/Chess   (208 words)

Encyclopedia: Buddy check The buddy check is a procedure carried out by SCUBA divers using the buddy system where each diver checks that the other's diving equipment is configured and functioning correctly. Check that these are secured to the diver, or else placed in a spot where they can be handed down once the diver is in the water. A secondary aim is to ensure that the buddy is familiar with the weight system of the diver being checked, and is able to operate them in an emergency www.nationmaster.com /encyclopedia/Buddy-check   (208 words)

Blank Check (film) - Wikipedia, the free encyclopedia Blank Check is a 1994 Disney live action movie about a boy whose bicycle is run over by an anonymous bank robber.

Betting (poker) - Wikipedia, the free encyclopedia In stud poker played in the United States, it is customary to signal folding by turning all of your cards face down. The bring-in is normally assigned on the first betting round of a stud poker game to the player whose upcards indicate the poorest hand. Finally, if a player folds out of turn in a stud poker game, the player in turn may demand that his upcards remain exposed until he has completed his turn. en.wikipedia.org /wiki/Check_(poker)   (4764 words)

Perpetual Calendars In the game of chess, perpetual check is a special case of draw by threefold repetition, in which one player forces the repetition by a series of checks. Perpetual check can also occur in other chess-like games, although the rules relating to it may be different. Perpetual motion machines are divided into two subcategories defined by which law of thermodynamics would have to be broken in order for the device to be a ''true'' perpetual motion machine. www.wwwtln.com /finance/144/perpetual-calendars.html   (1273 words)

parity Parity checks are still widely used for error checking in memory devices, where errors are likely to occur at random points. The problem with parity checks is that, in practice, errors do not affect randomly-placed bits in a message, but tend to occur in bursts: runs of all 1s or all 0s. All these (8, 7) parity check codes have exactly the properties: errors affecting one bit can be detected, but no errors can be corrected. www.kevinboone.com /compdict/compdict_parity.html   (1273 words)

Check digit calculation, Modulus 11, National Serials Data Program (Library of Congress) The purpose of a check digit is to guard against errors caused by the incorrect transcription of an ISSN. The modulus 11 basis using the weighting factors 8 to 2 for calculating the check digit is one of the most efficient systems for detecting transcription errors. It should be noted that the check digit is an essential and inseparable part of the ISSN. www.loc.gov /issn/check.html   (232 words)

Check In chess, if the king is in check and the threat cannot be stopped by interposing a piece, and the king cannot be moved without placing him back into check at the new location (or the king cannot be moved), the king is said to be checkmated and the game is over. In chess, when a check is answered by a check, particularly when this second check is delivered by a piece blocking the first, it is termed a cross-check. A check or cheque is a document instructing a financial institution to pay a specific amount of a specific currency from a specific demand account held in the issuer's name with that institution. www.brainyencyclopedia.com /encyclopedia/c/ch/check.html   (232 words)

check.html Check valves are used to prevent flow reversal, but due to the inertia and friction of the check valve components, limited flow reversal will still occur. Regardless of the initial velocity of the flow (as long as the check valve is fully open) the reverse velocity at which the valve closes is dependent only upon the valve geometry, mass of the valve, and the deceleration of the flow. The two objectives of this paper are: (1) to present a test method by which check valves can be dynamically tested for sudden closure due to reverse flow; and (2) to discuss the valve and pipe characteristics which affect the reverse velocities and pressure surges at the check valves. www.engineering.usu.edu /cee/faculty/rahm/check.html   (2017 words)

Safetyreliefvalves.Net Check valves allow the flow of liquids or gas in once direction and closes automatically when the flow stops or is reversed. The check valve is composed of a poppet, spring and surrounding polymers which are made from precision injection molded polymer. Some of the check valve systems they manufacture have the BASF Ultraform® which is an Acetal co-polymer as standard resin mainly due to its strength and chemical resistance and integrates poppet made of the similarly chemical resistant Santoprene® from Advanced Elastomer Systems. www.safetyreliefvalves.net /CheckValve.php   (593 words)

Check Valve The silent check valve applied on the outlet of the pump should be selected carefully, and it must be able to resist the highest pressure, the largest water hammer effect and the biggest fluid impact. The silent check valve is applied on lift pipe or fluid pipe with pressure. The valve gate, with restoring force, will be closed at suitable speed when the pump is shut down to separate the collision and noise between the inertia fluid (positive pressure) and the back flow (negative pressure) caused by power off. www.solenoidvalves.co.uk /CHF.htm   (203 words)

Longitudinal redundancy check - Wikipedia, the free encyclopedia A combination of longitudinal and vertical redundancy check allows the detection and correction of single bit errors. The block check formation rules are applied in the same manner to each character. In telecommunication, a longitudinal redundancy check (LRC) or horizontal redundancy check is a form of redundancy check based on the formation of a block check following preset rules: en.wikipedia.org /wiki/Longitudinal_redundancy_check   (181 words)
