Richard Hamming
Richard Wesley Hamming (February 11, 1915 – January 7, 1998) was an American mathematician whose work had many implications for computer engineering and telecommunications. His contributions include the Hamming code (which makes use of a Hamming matrix), the Hamming window, Hamming numbers, sphere-packing (or Hamming bound), Hamming graph concepts, and the Hamming distance. Born in Chicago, Hamming attended University of Chicago, University of Nebraska and the University of Illinois at Urbana–Champaign, where he wrote his doctoral thesis in mathematics under the supervision of Waldemar Trjitzinsky (1901–1973). In April 1945, he joined the Manhattan Project at the Los Alamos Laboratory, where he programmed the IBM calculating machines that computed the solution to equations provided by the project's physicists. He left to join the Bell Telephone Laboratories in 1946. Over the next fifteen years, he was involved in nearly all of the laboratories' most prominent achieveme ...

From 2007 to 2013, the award was accompanied by a prize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adjunct Professor
An adjunct professor is a type of academic appointment in higher education who does not work at the establishment full-time. The terms of this appointment and the job security of the tenure vary in different parts of the world, but the term is generally agreed to mean a bona-fide part-time faculty member in an adjunct position at an institution of higher education. Terminology An adjunct professor may also be called an adjunct lecturer, an adjunct instructor, or adjunct faculty. Collectively, they may be referred to as contingent academic labor. The rank of sessional lecturer in Canadian universities is similar to the US concept. Americas In the Academic ranks in the United States, United States, an adjunct is, in most cases, a non-Academic tenure, tenure-track faculty member. However, it can also be a scholar or teacher whose primary employer is not the school or department with which they have adjunct status. Adjunct professors make up the majority of instructors in higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calculating Machines
A mechanical calculator, or calculating machine, is a mechanical device used to perform the basic operations of arithmetic automatically, or a simulation like an analog computer or a slide rule. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator and the digital computer. Surviving notes from Wilhelm Schickard in 1623 reveal that he designed and had built the earliest known apparatus fulfilling the widely accepted definition of a mechanical calculator (a counting machine with an automated tens-carry). His machine was composed of two sets of technologies: first an abacus made of Napier's bones, to simplify multiplications and divisions first described six years earlier in 1617, and for the mechanical part, it had a dialed Pedometer#History, pedometer to perform additions and subtractions. A study of the surviving notes shows a machine that could have jammed after a few entries on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Alamos Laboratory
The Los Alamos Laboratory, also known as Project Y, was a secret scientific laboratory established by the Manhattan Project and overseen by the University of California during World War II. It was operated in partnership with the United States Army. Its mission was to design and build the History of nuclear weapons, first atomic bombs. J. Robert Oppenheimer was its first director, serving from 1943 to December 1945, when he was succeeded by Norris Bradbury. In order to enable scientists to freely discuss their work while preserving security, the laboratory was located on the isolated Pajarito Plateau in Northern New Mexico. The wartime laboratory occupied buildings that had once been part of the Los Alamos Ranch School. The development effort initially focused on a gun-type fission weapon using plutonium called Thin Man (nuclear bomb), Thin Man. In April 1944, the Los Alamos Laboratory determined that the rate of spontaneous fission in plutonium bred in a nuclear reactor was t ...

Waldemar Trjitzinsky
Waldemar, Valdemar, Valdimar, or Woldemar is an Old High German given name. It consists of the elements ''wald-'' "power", "brightness" and ''-mar'' "fame". The name is considered the equivalent of the Latvian name Valdemārs, the Estonian name Voldemar, and the Slavic names Vladimir, Volodymyr, Uladzimir or Włodzimierz. The Old Norse form ''Valdamarr'' (also ''Valdarr'') occurs in the Guðrúnarkviða II as the name of a king of the Danes. The Old Norse form is also used in Heimskringla, in the story of Harald Hardrada, as the name of a ruler of Holmgard (Veliky Novgorod).Alison Finlay (2004). ''Fagrskinna: A Catalogue of the Kings of Norway''. Brillp. 236 The ''Fagrskinna'' kings' sagas also have ''Valdamarr'', in reference to both Vladimir the Great and Vladimir Yaroslavovich. People with the name include: Royalty :''Ordered chronologically'' * Valdemar I of Denmark or Waldemar the Great (1131–1182), King of Denmark * Valdemar of Denmark (bishop) (1157/1158–1235 or ...

Hamming Graph
Hamming graphs are a special class of graphs named after Richard Hamming and used in several branches of mathematics (graph theory) and computer science. Let be a set of elements and a positive integer. The Hamming graph has vertex set , the set of ordered -tuples of elements of , or sequences of length from . Two vertices are adjacent if they differ in precisely one coordinate; that is, if their Hamming distance is one. The Hamming graph is, equivalently, the Cartesian product of complete graphs .. In some cases, Hamming graphs may be considered more generally as the Cartesian products of complete graphs that may be of varying sizes.. Unlike the Hamming graphs , the graphs in this more general class are not necessarily distance-regular, but they continue to be regular and vertex-transitive. Special cases *, which is the generalized quadrangle *, which is the complete graph . *, which is the lattice graph and also the rook's graph *, which is the singleton gra ...

Hamming Bound
In mathematics and computer science, in the field of coding theory, the Hamming bound is a limit on the parameters of an arbitrary block code: it is also known as the sphere-packing bound or the volume bound from an interpretation in terms of Sphere packing, packing balls in the Hamming metric into the Space (mathematics), space of all possible words. It gives an important limitation on the efficiency with which any error-correcting code can utilize the space in which its Code word (communication), code words are embedded. A code that attains the Hamming bound is said to be a perfect code. Background on error-correcting codes An original message and an encoded version are both composed in an alphabet of ''q'' letters. Each Code word (communication), code word contains ''n'' letters. The original message (of length ''m'') is shorter than ''n'' letters. The message is converted into an ''n''-letter codeword by an encoding algorithm, transmitted over a noisy communication channel, ch ...

Sphere-packing
In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions (where the problem becomes circle packing in two dimensions, or hypersphere packing in higher dimensions) or to non-Euclidean spaces such as hyperbolic space. A typical sphere packing problem is to find an arrangement in which the spheres fill as much of the space as possible. The proportion of space filled by the spheres is called the ''packing density'' of the arrangement. As the local density of a packing in an infinite space can vary depending on the volume over which it is measured, the problem is usually to maximise the average or asymptotic density, measured over a large enough volume. For equal spheres in three dimensions, the densest packing uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
