Contention City, Arizona
Contention City or Contention is a ghost mining town in Cochise County in the southeastern part of the U.S. state of Arizona. It was occupied from the early-1880s through the late-1880s in what was then known as the Arizona Territory. Only a few foundations now remain of this boomtown which was settled and abandoned with the rise and fall of silver mining in and around the area of Tombstone. History Prospectors Ed Williams and Jack Friday discovered what was to become the Contention and Grand Central mines when their mules broke free from a nearby camp one night. The mules, in search of water, dragged a chain behind them, which allowed Williams and Friday to track the animals the next morning. As they walked, they noticed the gleam of metal where the chain had scraped away the overlying dirt, and upon investigation, they found what would develop into a significant silver lode. The mules were tracked to the nearby camp of well-known prospector Ed Schieffelin, who had been prospec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contention, Oregon
Twickenham is an unincorporated community in Wheeler County, in the U.S. state of Oregon. It is located along the John Day River between Service Creek and Mitchell, Oregon. A bridge at Twickenham carries North Twickenham Road over the river. The locality was originally named ''Contention'' after a quarrel between two of its prominent residents. The Contention post office opened in 1886. A daughter of one of the residents involved in the quarrel suggested that the name ''Twickenham'', after the London suburb in England, would be more dignified than Contention. As it happened, the Contention post office closed in 1895, and a Twickenham post office opened in 1896 in the same general vicinity. It closed in 1917, and mail to Twickenham thereafter has been sent via Fossil, about to the north. After formation of Wheeler County in 1899, Twickenham was suggested as a possible county seat. A county-wide election held in 1900 produced 436 votes for Fossil, 267 for Twickenham, and 82 for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Contention
In computer science, resource contention is a conflict over access to a shared resource such as random access memory, disk storage, cache memory, internal buses or external network devices. A resource experiencing ongoing contention can be described as oversubscribed. Resolving resource contention problems is one of the basic functions of operating systems. Various low-level mechanisms can be used to aid this, including locks, semaphores, mutexes and queues. The other techniques that can be applied by the operating systems include intelligent scheduling, application mapping decision, and page coloring. Access to resources is also sometimes regulated by queuing; in the case of computing time on a CPU the controlling algorithm of the task queue is called a scheduler. Failure to properly resolve resource contention problems may result in a number of problems, including deadlock, livelock, and thrashing. Resource contention results when multiple processes attempt to use the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contention (telecommunications)
In statistical time division multiplexing, contention is a media access method that is used to share a broadcast medium. In contention, any computer in the network can transmit data at any time (first come-first served). This system breaks down when two computers attempt to transmit at the same time. This is known as a collision. To avoid collisions, a carrier sensing mechanism is used. Here each computer listens to the network before attempting to transmit. If the network is busy, it waits until network quiets down. In carrier detection, computers continue to listen to the network as they transmit. If computer detects another signal that interferes with the signal it is sending, it stops transmitting. Both computers then wait for a random amount of time and attempt to transmit. Contention methods are most popular media access control method on LANs. Collision detection and recovery One method to handle collisions in a contention based system is to optimize collision detection an ...

Bus Contention
Bus contention is an undesirable state in computer design where more than one device on a bus attempts to place values on it at the same time. Bus contention is the kind of telecommunication contention that occurs when all communicating devices communicate directly with each other through a single shared channel, and contrasted with "network contention" that occurs when communicating devices communicate indirectly with each other, through point-to-point connections through routers or bridges. Bus contention can lead to erroneous operation, excess power consumption, and, in unusual cases, permanent damage to the hardware—such as burning out a MOSFET. Ian Sinclair; John Dunton"Practical Electronics Handbook"2013. section "Three-state control". p. 208. Description Most bus architectures requires devices sharing a bus to follow an arbitration protocol carefully designed to make the likelihood of contention negligible.. However, when devices on the bus have logic errors, manuf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contention Ratio
In computer networking, the contention ratio is the ratio of the potential maximum demand to the actual bandwidth. The higher the contention ratio, the greater the number of users that may be trying to use the actual bandwidth at any one time and, therefore, the lower the effective bandwidth offered, especially at peak times.UK OFCOM research report annex on broadban/ref> A ''contended service'' is a service which offers the users of the network a minimum statistically guaranteed contention ratio, while typically offering peaks of usage of up to the maximum bandwidth supplied to the user. Contended services are usually much cheaper to provide than uncontended services, although they only reduce the backbone traffic costs for the users, and do not reduce the costs of providing and maintaining equipment for connecting to the network. Examples by country In the United Kingdom, a Rate Adaptive Digital Subscriber Line ( RADSL) connection used to be marketed with a contention ratio bet ...

FV4401 Contentious
FV 4401 ''Contentious'' was a prototype British air-portable tank destroyer of the early 1960s. At least one prototype was constructed and tested, although no production vehicles were built or saw service. Project ''Prodigal'' The vehicle was developed as part of '' Project Prodigal'', which give rise to the CVR(T) series of British light tanks and related vehicles. as research into future armoured fighting vehicles. The intention was to produce an air-portable tank destroyer. The vehicle was to provide for a flexible strategic response to conflicts around the vestiges of the Empire. Despite the low intensity of such conflicts, it was assumed that the increasing supply of Soviet T-54 tanks to satellite states would require an anti-tank capability greater than previous light tanks. This was ''not'' seen as a substitute for a main battle tank, which would have to be heavily armed to deal with the massed and thickly armoured Soviet tanks of the Cold War. In particular, there w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument
An argument is a statement or group of statements called premises intended to determine the degree of truth or acceptability of another statement called conclusion. Arguments can be studied from three main perspectives: the logical, the dialectical and the rhetorical perspective. In logic, an argument is usually expressed not in natural language but in a symbolic formal language, and it can be defined as any group of propositions of which one is claimed to follow from the others through deductively valid inferences that preserve truth from the premises to the conclusion. This logical perspective on argument is relevant for scientific fields such as mathematics and computer science. Logic is the study of the forms of reasoning in arguments and the development of standards and criteria to evaluate arguments. Deductive arguments can be valid, and the valid ones can be sound: in a valid argument, premisses necessitate the conclusion, even if one or more of the premises is false ...

Controversy
Controversy is a state of prolonged public dispute or debate, usually concerning a matter of conflicting opinion or point of view. The word was coined from the Latin ''controversia'', as a composite of ''controversus'' – "turned in an opposite direction". Legal In the theory of law, a controversy differs from a legal case; while legal cases include all suits, criminal as well as civil, a controversy is a purely civil proceeding. For example, the Case or Controversy Clause of Article Three of the United States Constitution ( Section 2, Clause 1) states that "the judicial Power shall extend ... to Controversies to which the United States shall be a Party". This clause has been deemed to impose a requirement that United States federal courts are not permitted to cases that do not pose an actual controversy—that is, an actual dispute between adverse parties which is capable of being resolved by the ourt In addition to setting out the scope of the jurisdiction of t ...

Contentious Jurisdiction
In English ecclesiastical law, contentious jurisdiction (Latin: ''forum contentiosum'') is jurisdiction over matters in controversy between parties, in contradistinction to ''voluntary'' jurisdiction, or that exercised upon matters not opposed or controverted. The Lords Chief Justices, judges, etc., had a contentious jurisdiction; but, the Lords of the Treasury In the United Kingdom there are at least six Lords Commissioners of His Majesty's Treasury, serving as a commission for the ancient office of Treasurer of the Exchequer. The board consists of the First Lord of the Treasury, the Second Lord of the ..., the Commissioners of Customs, etc., have none, being merely judges of the accounts.
