Block Register Territory
Block register territory (BRT) is a designation applied to some lightly used segments of railroad track in the United States. In these areas, trains are only authorized to move into the territory when a special type of log book is filled out correctly. BRT is described in the General Code of Operating Rules The General Code of Operating Rules (GCOR) is a set of operating rules for railroads in the United States. The GCOR is used by Class I railroads west of Chicago, most of the Class II railroads, and many Short-line railroads. Some railroads in nort ... (GCOR) as Rule 6.15. A standard block register has rows divided into five columns: *An identifier for the train, work crew, or other equipment using the line *The last name of the employee in charge of the equipment or crew *The current date *The time at which the track was entered *The time at which the track was cleared The first four columns of the register are filled out upon entering the block. When the track is exited, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gradient Boosting
Gradient boosting is a machine learning technique used in regression and classification tasks, among others. It gives a prediction model in the form of an ensemble of weak prediction models, which are typically decision trees. When a decision tree is the weak learner, the resulting algorithm is called gradient-boosted trees; it usually outperforms random forest. A gradient-boosted trees model is built in a stage-wise fashion as in other boosting methods, but it generalizes the other methods by allowing optimization of an arbitrary differentiable loss function. History The idea of gradient boosting originated in the observation by Leo Breiman that boosting can be interpreted as an optimization algorithm on a suitable cost function. Explicit regression gradient boosting algorithms were subsequently developed, by Jerome H. Friedman, simultaneously with the more general functional gradient boosting perspective of Llew Mason, Jonathan Baxter, Peter Bartlett and Marcus Frean. ...

Black Russian Terrier
The Black Russian Terrier (russian: Русский чёрный терьер), also known as the Chornyi Terrier (''chornyi'' being Russian for black) is a breed of dog created in USSR in Red Star (Krasnaya Zvezda) Kennel during the late 1940s and the early 1950s for use as military/working dogs. At the present time, the Black Russian Terrier is a breed recognized by the FCI ( FCI's from September 1983), AKC ( AKC's from July 2004), CKC, KC, ANKC, NZKC and other cynological organizations. The contemporary Black Russian Terrier is a working dog, guarding dog, sporting and companion dog. Despite its name, the Black Russian Terrier is not a true terrier: it is believed that about seventeen breeds were used in its development, including the Airedale, the Giant Schnauzer, the Rottweiler, the Newfoundland, the Caucasian Shepherd Dog and other breeds. History The Black Russian Terrier was developed in the former USSR in Red Star (Krasnaya Zvezda) Kennel by the state for use as a milit ...

Business Roundtable
The Business Roundtable (BRT) is a nonprofit lobbyist association based in Washington, D.C. whose members are chief executive officers of major United States companies. Unlike the U.S. Chamber of Commerce, whose members are entire businesses, BRT members are exclusively CEOs. The BRT lobbies for public policy that is favorable to business interests, such as lowering corporate taxes in the United States and internationally, as well as international trade policy, like NAFTA. In 2019, BRT redefined its definition of the purpose of a corporation as participating in stakeholder capitalism, putting the interests of employees, customers, suppliers and communities on par with shareholders. BRT board members include, in 2021, chair Doug McMillon of Walmart, president and CEO, former White House Chief of Staff Joshua Bolten, Mary Barra of General Motors, Tim Cook of Apple, and Chuck Robbins of Cisco. History On October 13, 1972, the March Group, co-founded by Alcoa chairman John D. Harper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vlaamse Radio- En Televisieomroep
The VRT (), is the national public-service broadcaster for the Flemish Community of Belgium. History VRT is the successor to a succession of organisations. The Belgian National Institute of Radio Broadcasting was known as the Nationaal Instituut voor de Radio-omroep (NIR) in Flemish and the L'Institut National de Radiodiffusion (INR) in French, was founded in 1930 and existed until 1960. This became the Belgische Radio- en Televisieomroep (BRT) in 1960 and the Belgische Radio- en Televisieomroep Nederlandstalige Uitzendingen (BRTN) from 1991 to 1998. The NIR/INR and BRT (Radio-Télévision Belge, or RTB, in French) had each been single state-owned entities with separate Dutch- and French-language production departments. They were housed in Le Flagey, formerly known as the Maison de la Radio, from when the new building was completed in 1938 until 1974, when the building became too small. However, in 1977, as part of the ongoing state reform in Belgium broadcasting became r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayrak
Bayrak Radio and Television Corporation ( tr, Bayrak Radyo Televizyon Kurumu; BRT), is the official radio and television broadcasting corporation of the Turkish Republic of Northern Cyprus. History The establishment of BRT dates back to the events of December 1963 when intercommunal violence between the Greek and Turkish communities effectively ended the cooperative Republic of Cyprus splitting the island into two as north and south. Until that time, the Cyprus Broadcasting Corporation (CyBC) was run by Greek Cypriots with minority participation by Turkish Cypriots, who had no independent news source and had to depart from CyBC as the inter communal issues became more violent. Bayrak Radio was established on 25 December 1963 to voice the cause of Turkish Cypriots. Bayrak Radio began as a clandestine homemade station, put together with a few pieces of homemade electrical equipment, which was powered by a car battery. It started transmitting within a limited radius of 2.5&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thyristor
A thyristor () is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means). There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large (breakdown voltage). Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous. Other sources define thyristors as more complex devices that incorporate at least four layers of alternating N-type and P-type substrate. The first thyristor devices were ...

British Rail Telecommunications
British Rail Telecommunications was created in 1992 by British Rail (BR). It was the largest private telecoms network in Britain, consisting of 17,000 route kilometres of fibre optic and copper cable which connected every major city and town in the country and provided links to continental Europe through the Channel Tunnel. BR also operated its own national trunked radio network, providing dedicated train-to-shore mobile communications, and in the early 1980s BR helped establish Mercury Communications’ (now Vodafone) core infrastructure by laying a resilient figure-of-eight fibre optic network alongside Britain's railway lines, spanning London, Bristol, Birmingham, Leeds and Manchester. Realising the enormous commercial potential, BR Telecommunications Limited (BRT) was created in 1992 to exploit its wayleave rights and to take responsibility for the management and maintenance of the industry's voice, data and radio networks associated with the operational running of the railway ...
