GF(2)
(also denoted \mathbb F_2, or \mathbb Z/2\mathbb Z) is the finite field of two elements (GF is the initialism of ''Galois field'', another name for finite fields). Notations and \mathbb Z_2 may be encountered although they can be confused with the notation of -adic integers. is the field with the smallest possible number of elements, and is unique if the additive identity and the multiplicative identity are denoted respectively and , as usual. The elements of may be identified with the two possible values of a bit and to the boolean values ''true'' and ''false''. It follows that is fundamental and ubiquitous in computer science and its logical foundations. Definition GF(2) is the unique field with two elements with its additive and multiplicative identities respectively denoted and . Its addition is defined as the usual addition of integers but modulo 2 and corresponds to the table below: If the elements of GF(2) are seen as boolean values, then the addition is th ...

Fluorine
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative reactive element, it is extremely reactive, as it reacts with all other elements except for the light inert gases. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial abundance. Fluorite, the primary mineral source of fluorine which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb meaning 'flow' gave the mineral its name. Proposed as an element in 1810, fluorine proved difficult and dangerous to separate from its compounds, and several early experimenters died or sustained injuries from their attempts. Only in 1886 did French chemist Henri Moissan isolate elemental fluorine using low-temperature electrolysis, a process still employed for modern pr ...

DKW (''Dampf-Kraft-Wagen'', en, "steam-powered car", also ''Deutsche Kinder-Wagen'' en, "German children's car". ''Das-Kleine-Wunder'', en, "the little wonder" or ''Des-Knaben-Wunsch'', en, "the boy's wish"- from when the company built toy two-stroke engines) was a German car- and motorcycle- marque. DKW was one of the four companies that formed Auto Union in 1932 and thus became an ancestor of the modern-day Audi company. In 1916, Danish engineer Jørgen Skafte Rasmussen founded a factory in Zschopau, Saxony, Germany, to produce steam fittings. That year he attempted to produce a steam-driven car, called the DKW.Odin, L.C. ''World in Motion 1939 – The whole of the year's automobile production''. Belvedere Publishing, 2015. ASIN: B00ZLN91ZG.

Alta F2
The Alta Car and Engineering Company was a British sports and racing car manufacturer, commonly known simply as Alta. Their cars contested five FIA World Championship races between 1950 and 1952, as well as Grand Prix events prior to this. They also supplied engines to a small number of other constructors, most notably the Connaught and HWM teams. Early history The company was founded by engineer Geoffrey Taylor (1903–1966) in Surbiton, Surrey, and produced its first automobile in 1929. Alta's first vehicle was a sports car powered by a 1.1L engine, featuring an aluminium block, wet liners, and shaft-driven twin overhead camshafts, which Taylor designed himself. It was offered in naturally aspirated or supercharged form giving . A choice of four speed non- synchromesh or pre-selector gearboxes was available. These were mounted on a low-slung chassis frame with open two- or four-seat bodies. Thirteen were made, of which five are thought to survive. This design, and i ...

H&BR Class F2
The H&BR Class F2 (LNER Class N12) was a class of 0-6-2T steam locomotives of the Hull and Barnsley Railway. It was designed by Matthew Stirling and nine locomotives were built by Kitson & Co. in 1901. Equipment The locomotives had domeless boilers and rounded cabs and were fitted with vacuum brakes. After the Grouping in 1923, they were rebuilt with a variety of boilers, some domed and some domeless. Use They were used for goods trains, banking, assembling mineral trains in colliery sidings and occasionally for passenger work. Withdrawal All but one were withdrawn between 1936 and 1938. The survivor passed to British Railways British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997.

EMD F2
The EMD F2 was a freight-hauling diesel locomotive built by General Motors Electro-Motive Division between July 1946 and November 1946. It succeeded the FT model in GM-EMD's F-unit sequence, and was replaced in turn by the F3. The F2 was in many respects a transitional type between those two; it kept the rated D8 generator from the FT due to late development of the new D12 generator intended for the F3, but in a revised carbody design and internal layout that would be continued through the rest of the F-unit series. 74 cab-equipped lead A units and 30 cabless booster B units were produced. There are no reliable recognition features for an F2. They were built with what has become known as 'Type 1' side panels, with three portholes and no filter grilles, but this was carried over into early F3 production and in any case, could be changed later by the customer. Like some early F3s, they were built with small side numberboards on the nose. They, and all subsequent F-units, are re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
