Bridged Amplifier
Multiple electronic amplifiers can be connected such that they drive a single floating load (bridge) or a single common load (parallel), to increase the amount of power available in different situations. This is commonly encountered in audio applications. Overview Bridged or paralleled modes of working, normally involving audio power amplifiers, are methods of using a two or more identical amplifiers to drive the same load simultaneously. This is possible for sets of mono, stereo and multichannel amplifiers since the amplifier outputs are combined on a per load basis. Depending on the method of combining separate amplifiers, bridging or paralleling, different amplification goals can be served. The result is an amplifier that can be further combined with bridging or paralleling. This approach can be beneficial for driving loads for which using a single-ended amplifier is impossible, impractical or less cost-effective.

Bicyclic Molecule
In chemistry, a bicyclic molecule () is a molecule that features two joined rings. Bicyclic structures occur widely, for example in many biologically important molecules like α-thujene and camphor. A bicyclic compound can be carbocyclic (all of the ring atoms are carbons), or heterocyclic (the rings' atoms consist of at least two elements), like DABCO. Moreover, the two rings can both be aliphatic (''e.g.'' decalin and norbornane), or can be aromatic (''e.g.'' naphthalene), or a combination of aliphatic and aromatic (''e.g.'' tetralin). Three modes of ring junction are possible for a bicyclic compound: * In spirocyclic compounds, the two rings share only one single atom, the spiro atom, which is usually a quaternary carbon. An example of a spirocyclic compound is the photochromic switch spiropyran. * In fused/condensed bicyclic compounds, two rings share two adjacent atoms. In other words, the rings share one covalent bond, ''i.e.'' the so-called bridgehead atoms are direc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridging (networking)
A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments. This function is called network bridging. Bridging is distinct from routing. Routing allows multiple networks to communicate independently and yet remain separate, whereas bridging connects two separate networks as if they were a single network. In the OSI model, bridging is performed in the data link layer (layer 2). If one or more segments of the bridged network are wireless, the device is known as a wireless bridge. The main types of network bridging technologies are simple bridging, multiport bridging, and learning or transparent bridging. Transparent bridging Transparent bridging uses a table called the forwarding information base to control the forwarding of frames between network segments. The table starts empty and entries are added as the bridge receives frames. If a destination address entry is not found in the table, ...

Bridging (programming)
In computer science, bridging describes systems that map the runtime behaviour of different programming languages so they can share common resources. They are often used to allow "foreign" languages to operate a host platform's native object libraries, translating data and state across the two sides of the bridge. Bridging contrasts with "embedding" systems that allow limited interaction through a black box mechanism, where state sharing is limited or non-existent. Apple Inc. has made heavy use of bridging on several occasions, notably in early versions of Mac OS X which bridged to older "classic" systems using the Carbon system as well as Java. Microsoft's Common Language Runtime, introduced with the .NET Framework, was designed to be multi-language from the start, and avoided the need for extensive bridging solutions. Both platforms have more recently added new bridging systems for JavaScript, Apple's ObjC-to-JS and Microsoft's HTML Bridge. Concepts Functions, libraries and ru ...

Bridge
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The '' Oxford English Dictionary'' traces the origin of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impedance Bridging
In audio engineering and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one in which the load impedance is much larger than the source impedance. The load measures the source's voltage while minimally drawing current or affecting it. Explanation When the output of a device (consisting of the voltage source ''V''S and output impedance ''Z''S in illustration) is connected to the input of another device (the load impedance ''Z''L in the illustration), these two impedances form a voltage divider: : V_L = \frac V_S \, . One can maximize the signal level ''V''L by using a voltage source whose output impedance ''Z''S is as small as possible and by using a receiving device whose input impedance ''Z''L is as large as possible. When Z_L \gg Z_S (typically by at least ten times), this is called a ''bridging connection'' and has a number of effects including: * Advantages: ** Reduces the 6dB attenuation incurred by impedance matching ...

Cue Stick
A cue stick (or simply cue, more specifically billiards cue, pool cue, or snooker cue) is an item of sporting equipment essential to the games of pool, snooker and carom billiards. It is used to strike a ball, usually the . Cues are tapered sticks, typically about 57–59 inches (about 1.5 m) long and usually between 16 and 21 ounces (450–600 g), with professionals gravitating toward a 19-ounce (540 g) average. Cues for carom tend toward the shorter range, though cue length is primarily a factor of player height and arm length. Most cues are made of wood, but occasionally the wood is covered or bonded with other materials including graphite, carbon fiber or fiberglass. An obsolete term for a cue, used from the 16th to early 19th centuries, is billiard stick. History The forerunner of the cue was the , an implement similar to a light-weight golf club, with a foot that was generally used to shove rather than strike the cue ball. When the ball was ag ...

Bridge (exercise)
The bridge (also called gymnastic bridge) is an exercise. Many variations of this exercise are employed throughout the world, most commonly the balancing of the body on the hands and the feet. It is intended to improve lower back and gluteus strength. Examples of bridging in sportive or self-defense applications are seen in Kung Fu, Judo, Brazilian jiu jitsu, Capoeira, mixed martial arts, and wrestling. In yoga, this particular pose is called Chakrasana, Urdhva Dhanurasana, or Wheel, while the Westernized nickname "Bridge pose" refers to a less rigorous supine backbend called Setu Bandha Sarvangasana, in which the body is fairly straight from knees to shoulders, and most of the bend is in the knees. Variations The bridging exercise is not a singular movement, but includes a wide range of variations and progressions. There is no single agreed upon "standard" variation of the bridge like with other common bodyweight exercises. Bridge hold The bridge hold is a static variat ...

Grappling
Grappling, in hand-to-hand combat, describes sports that consist of gripping or seizing the opponent. Grappling is used at close range to gain a physical advantage over an opponent, either by imposing a position or causing injury. Grappling is a broad term that encompasses many disciplines. These various martial arts can be practiced both as combat sports and for self-defense. Grappling contests often involve takedowns and ground control, and may end when a contestant concedes defeat, also known as a submission or tap out. Grappling most commonly does not include striking or the use of weapons. However, some fighting styles or martial arts known especially for their grappling techniques teach tactics that include strikes and weapons either alongside grappling or combined with it. Grappling appeared in the 1950s. Types of technique Grappling techniques can be broadly subdivided into clinch fighting; takedowns and throws; submission holds and pinning or controll ...

Mount (grappling)
The mount, or mounted position, is a dominant ground grappling position, where one combatant sits on the other combatants torso with the face pointing towards the opponent's head. This is a favorable position for the top combatant in several ways. The top combatant can generate considerable momentum for strikes (such as punches or elbows) to the head of the opponent, while the bottom combatant is restricted by the ground and by the combatant on top. Other advantages include various chokeholds and joint locks that can be applied from the top. The bottom combatant will usually look to sweep the opponent or transition into a better position such as the guard. Variations of the mount A mount which is very high up on the opponent's chest is referred to as a high mount, and a very low one on the abdomen or even thighs as a low mount. A high mount can be used to pin one of the opponents arms under the knee, so as to prevent him or her from defending effectively. This however might i ...

Bench Pressing
The bench press, or chest press, is a weight training exercise in which the trainee presses a weight upwards while lying on a weight training bench. Although the bench press is a full-body exercise, the muscles primarily used are the pectoralis major, the anterior deltoids, and the triceps, among other stabilizing muscles. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used. The barbell bench press is one of three lifts in the sport of powerlifting alongside the deadlift and squat, and is the only lift in the sport of Paralympic powerlifting. The bench press is an upper body mass-building exercise that stresses some of the body’s largest muscles, including chest, triceps, shoulders, front deltoids, and even upper back. It is also used extensively in weight training, bodybuilding, and other types of training to develop the chest muscles. Bench press strength is important in combat sports as it tightly correlates to punching power. Bench pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billiards
Cue sports are a wide variety of games of skill played with a cue, which is used to strike billiard balls and thereby cause them to move around a cloth-covered table bounded by elastic bumpers known as . There are three major subdivisions of games within cue sports: *Carom billiards, played on tables without , typically 10 feet in length, including straight rail, balkline, one-cushion carom, three-cushion billiards, artistic billiards, and four-ball *Pool, played on six-pocket tables of 7-, 8-, 9-, or 10-foot length, including among others eight-ball (the world's most widely played cue sport), nine-ball (the dominant professional game), ten-ball, straight pool (the formerly dominant pro game), one-pocket, and bank pool *Snooker, English billiards, and Russian pyramid, played on a large, six-pocket table (dimensions just under 12 ft by 6 ft), all of which are classified separately from pool based on distinct development histories, player culture, rules, and termin ...
