Binary-coded Decimal
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow). In byte-oriented systems (i.e. most modern computers), the term ''unpacked'' BCD usually implies a full byte for each digit (often including a sign), whereas ''packed'' BCD typically encodes two digits within a single byte by taking advantage of the fact that four bits are enough to represent the range 0 to 9. The precise four-bit encoding, however, may vary for technical reasons (e.g. Excess-3). The ten states representing a BCD digit are sometimes called '' tetrades'' (the nibble typically needed to hold them is also known as a tetrade) while the unused, don't care-states are named ''pseudo-tetrad(e)s'', ''pseudo-decimals'', or ''pseudo-decimal digits''. BCD's main virtue, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicycle Brake
A bicycle brake reduces the speed of a bicycle or prevents the wheels from moving. The two main types are: #Rim brakes, rim brakes and #Disc brakes, disc brakes. Drum brakes are less common on bicycles. Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as #Brake levers, brake levers or Bicycle pedal, pedals; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, #Rod-actuated brakes, rods, or the bicycle chain; and the brake mechanism itself, a #Rim brakes, caliper or #Drum brakes, drum, to press two or more surfaces together in order to convert, via friction, kinetic energy of the bike and rider into thermal energy to be Dissipation, dissipated. History Karl Drais included a pivoting brake shoe that could be pressed against the rear iron tyre of his 1817 . This was continued on the earliest bicycles with pedals, such as the Boneshaker (bicycle)#Boneshaker, boneshaker, which were fitted with ...

Crankset
The crankset (in the US) or chainset (in the UK) is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called ''chainrings'' or ''chainwheels'' attached to the '' cranks'', ''arms'', or ''crankarms'' to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain. Parts Cranks The two ''cranks'', one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals. Lengths Bicycle cranks can vary in length to accommodate different sized riders and different types of cycling. Crank length is measured from the center of the pedal spindle to the center of the bottom bracket spindle or axle. The larger bicycle component manufacturers typically offe ...

Buoyancy Control Device
Buoyancy (), or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may be also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the displaced fluid. For this reason, an object with average density greater than the surrounding fluid tends to sink because its weight is greater than the weight of the fluid it displaces. If the object is less dense, buoy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Credentials In Psychology
This list is of professional and academic credentials in the field of psychology and allied fields in North America, including education, counseling, social work, and family therapy. Degrees Although undergraduate (Bachelor's) degrees for psychology and counseling exist, in most jurisdictions the minimum requirement for professional licensure is a graduate degree (master's or doctorate). ;Associate degrees * Associate of Art (AA) or Associate of Science (AS): Associate degrees are usually two-year degrees and are often offered at community colleges. Many choose to start with associate degrees in counseling psychology, clinical psychology, or related fields, before starting work on degrees which require further education. An associate degree is usually not required in order to enroll in a bachelor's degree program. An associate degree does not meet the requirements for clinical practice or licensure. ;Bachelor's degrees *Bachelor of Arts (BA), Bachelor of Science (BS): Bachelor's ...

Blue Compact Dwarf Galaxy
A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way's 200–400 billion stars. The Large Magellanic Cloud, which closely orbits the Milky Way and contains over 30 billion stars, is sometimes classified as a dwarf galaxy; others consider it a full-fledged galaxy. Dwarf galaxies' formation and activity are thought to be heavily influenced by interactions with larger galaxies. Astronomers identify numerous types of dwarf galaxies, based on their shape and composition. Formation One theory states that most galaxies, including dwarf galaxies, form in association with dark matter, or from gas that contains metals. However, NASA's Galaxy Evolution Explorer space probe identified new dwarf galaxies forming out of gases with low metallicity. These galaxies were located in the Leo Ring, a cloud of hydrogen and helium around two massive galaxies in the constellation Leo. Because of their small size, dwarf galaxies have bee ...

Barrels Per Calendar Day
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the U.K. beer barrel and U.S. beer barrel), oil barrels, and so forth. For historical reasons, the volumes of some barrel units are roughly double the volumes of others; volumes in common use range approximately from . In many connections, the term is used almost interchangeably with ''barrel''. Since medieval times, the term as a unit of measure has had various meanings throughout Europe, ranging from about 100 litres to about 1,000 litres. The name was derived in medieval times from the French , of unknown origin, but still in use, both in French and as derivations in many other languages, such as Italian, Polish, and Spanish. In most countries, such usage is obsolescent, having been superseded by SI units. As a result, the meaning of corresponding words and related concepts (vat, cask, keg etc.) in other languages often refers to a physical contain ...

Bad Conduct Discharge
A military discharge is given when a member of the armed forces is released from their obligation to serve. Each country's military has different types of discharge. They are generally based on whether the persons completed their training and then fully and satisfactorily completed their term of service. Other types of discharge are based on factors such as the quality of their service, whether their service had to be ended prematurely due to humanitarian or medical reasons, whether they had been found to have drug or alcohol dependency issues and whether they were complying with treatment and counseling, and whether they had demerits or punishments for infractions or were convicted of any crimes. These factors affect whether they will be asked or allowed to re-enlist and whether they qualify for benefits after their discharge. United Kingdom There are several reasons why someone may be discharged from the military, including expiration of enlistment, disability, dependency and ...

Beirut Central District
The Beirut Central District is the historical and geographical central business district, core of Beirut, the capital of Lebanon. Also called downtown Beirut, it has been described as the “vibrant financial, commercial, and administrative hub of the country.” It is thousands of years old, with a traditional focus of business, finance, culture, and leisure. The area is situated on the city's northern coast and is easily accessible from all parts of the city. This includes the adjacent port of beirut, Beirut Seaport and Rafik Hariri International Airport. Major roads converge on it or from boundaries to the east, south and west, or line its long seafront to the north. After the city center was destroyed by the Lebanese Civil War, it underwent thorough reconstruction and development, which restored its cultural and economic position in the region. A master plan for reconstructing the city was officially approved by the Lebanese Government in March 1994 after a series of de ...
