Simplex
In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope in any given dimension. For example, * a 0-dimensional simplex is a point, * a 1-dimensional simplex is a line segment, * a 2-dimensional simplex is a triangle, * a 3-dimensional simplex is a tetrahedron, and * a 4-dimensional simplex is a 5-cell. Specifically, a ''k''-simplex is a ''k''-dimensional polytope which is the convex hull of its ''k'' + 1 vertices. More formally, suppose the ''k'' + 1 points u_0, \dots, u_k \in \mathbb^ are affinely independent, which means u_1 - u_0,\dots, u_k-u_0 are linearly independent. Then, the simplex determined by them is the set of points : C = \left\ This representation in terms of weighted vertices is known as the barycentric coordinate system. A regular simplex is a simplex that is also a regular polytope. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motor Rail
Motor Rail was a British locomotive-building company, originally based in Lewes, Sussex, they moved in 1916 to Bedford. In 1987 loco manufacture ceased, and the business line sold to Alan Keef Ltd of Ross-on-Wye, who continue to provide spares and have built several locomotives to Motor Rail designs. History The origins of the Motor Rail company can be traced back to the patenting of a gearbox by John Dixon Abbott of Eastbourne in 1909 ("Change speed and reversing gearbox suitable for use in motor-trams", UK Patent 18314). In March 1911, he formed The Motor Rail & Tramcar Co Ltd, with his father John Abbott and brother Tom Dixon Abbott. The stated aim of the business was developing the gearbox and incorporating it in tramcars and railcars. At about the same time operations moved to Lewes, Sussex and rented space in the Phoenix Foundry of John Every, where they developed a narrow-gauge rail vehicle around the Dixon-Abbott gearbox using a twin cylinder water-cooled Dorman engin ...

Mercedes Simplex
The Mercedes Simplex was an automobile produced from 1902 to 1909 by the Daimler Motoren Gesellschaft (DMG, Daimler Motor Society, a predecessor of Daimler-Benz and Daimler-Chrysler). It continued the use of the Mercedes name as the brand of DMG, rather than Daimler. The Mercedes Simplex was designed by Wilhelm Maybach in Stuttgart, Germany. It featured powerful engines whose power ranged from 40 to 60 hp. Its large and wide body had a low center of gravity. A highlight of the Simplex family was the model 60 hp. With this car Mercedes laid the foundation of a new car segment, the super-luxury class with an imposing touring Saloon body, it was unlike anything else at the time and quickly established itself well with royalty and aristocrats. Its immense size and luxuries were to set the milestones for the development of this segment, which was continued on by numerous models over the next 70 odd years, including the 630, 770 Grand, 300 Adenauer and terminating in 1981 with ...

Small Innovative Missions For Planetary Exploration
Small Innovative Missions for Planetary Exploration (SIMPLEx) is a planetary exploration program operated by NASA. The program funds small, low-cost spacecraft for stand-alone planetary exploration missions. These spacecraft are intended to launch as secondary payloads on other missions and are riskier than Discovery or New Frontiers missions. The program selects missions from multiple proposals and gives them some money to begin development. After early development they are analyzed to see if they are cost-effective and scientifically valuable during Key Decision Point-C. If they pass Key Decision Point-C then they move into full development. The missions must weigh less than 180 kg. So far only the first two missions have launched, and the remaining missions have struggled to stay within budget and find missions to launch with, and have been removed from multiple launches. Missions On August 8, 2015, the first two SIMPLEx missions were selected: Q-PACE and LunaH-Map.NASASm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simplex Signaling
Simplex signaling (SX) is signaling In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' ... in which two conductors are used for a single telecommunication circuit, and a center-tapped coil, or its equivalent, is used to split the signaling current equally between the two conductors. The return path for the current is through ground. It is distinct from a phantom circuit in which the return current path for power or signaling is provided through different signal conductors. SX signaling may be one-way, for intra-central-office use, or the simplex legs may be connected to form full-duplex signaling circuits that function like composite (CX) signaling circuits with E&M lead control. Simplex is also used to describe a powering method where one or more signal conductors carries direct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simplex Communication
Simplex communication is a communication channel that sends information in one direction only."Simplex" ''The IEEE Authoritative Dictionary of Standard Terms, 7th Ed.'', 2000, Inst. of Electrical and Electronic Engineers, p.1053 The International Telecommunication Union definition is a communications channel that operates in one direction at a time, but that may be reversible; this is termed half duplex in other contexts. A duplex communication channel requires two simplex channels operating in opposite directions at the same time. For example, in TV and radio broadcasting, information flows only from the transmitter site to multiple receivers. A pair of walkie-talkie two-way radios provide a simplex circuit in the ITU sense; only one party at a time can talk, while the other listens until it can hear an opportunity to transmit. The transmission medium (the radio signal over the air) can carry information in only one direction. The old Western Union company used the term simpl ...

Wurlitzer
The Rudolph Wurlitzer Company, usually referred to as simply Wurlitzer, is an American company started in Cincinnati in 1853 by German immigrant (Franz) Rudolph Wurlitzer. The company initially imported stringed, woodwind and brass instruments from Germany for resale in the United States. Wurlitzer enjoyed initial success, largely due to defense contracts to provide musical instruments to the U.S. military. In 1880, the company began manufacturing pianos and eventually relocated to North Tonawanda, New York. It quickly expanded to make band organs, orchestrions, player pianos and pipe or theatre organs popular in theatres during the days of silent movies. Wurlitzer is most known for their production of entry level pianos. During the 1960s, they manufactured Spinet, Console, Studio and Grand Pianos. Over time, Wurlitzer acquired a number of other companies which made a variety of loosely related products, including kitchen appliances, carnival rides, player piano rolls and radi ...
