Walsh (surname)
Walsh is a common Irish surname, meaning "Briton" or "foreigner", literally "Welshman" or "Wales", taken to Ireland by soldiers from Britain, namely Cambro-Norman/Welsh, Cornish and Cumbrian soldiers during and after the Norman invasion of Ireland. It is most common in County Mayo and County Kilkenny. It is the fourth most common surname in Ireland, and the 265th most common in the United States. There are variants including "Walshe", “ Welch”, "Welsh", "Brannagh", and the Irish "Breathnach". Walsh is uncommon as a given name. The name is often pronounced "Welsh" in the south and west of the country. In Great Britain, Guppy encountered the name only in Lancashire. It is the surname of the Barons Ormathwaite. Origins in Ireland There are several Walsh families in Ireland who have recognized coats of arms. These are the Walshs of Ballykilcaven in County Laois whose motto is "Firm" and their crest is a griffin's head. The Walshs of Castlehale in County Kilkenny have a crest ...

Walsh College
Walsh College is a private college focused on business education with its main campus in Troy, Michigan. It was founded in 1922. History The college began with the founding of the Walsh Institute of Accountancy and the introduction of the Pace Accounting Method, at the time an innovative way of teaching accounting. Mervyn B. Walsh, a certified public accountant, purchased a Pace & Pace franchise to offer the Pace Accounting Method exclusively in Detroit. He founded the Walsh Institute of Accountancy on July 7, 1922, and on September 18 of that year, 23 students were enrolled in the first courses at the institute. When Mervyn Walsh retired in 1965, the state of Michigan had adopted a new bachelor's degree requirement for candidates to sit for the Uniform Certified Public Accountant (CPA) Examination. At this time, Michigan's community college system was developing and a pivotal decision was made to build upon, rather than compete with, the community colleges by becoming an uppe ...

Walsh Convention
:''See the Glossary of contract bridge terms for an explanation of unfamiliar words or phrases.'' Walsh is a convention used in the card game of bridge in response to an opening bid of 1. The convention has its origins in the Walsh System developed by Richard Walsh. In general, the Walsh convention is not used in four-card major systems such as Acol, but may be employed in some five-card major systems; especially those that use a prepared club, rather than better minor. The opening bid of 1 will therefore have shown either clubs or a balanced hand. When responder is too weak to force to game diamond suits are bypassed in favour of major suits, regardless of the length of the diamond suit. For example, holding , the response to the opening bid of 1 would be 1 rather than the normal 1. Continuations vary according to other details of the system being played. If Checkback Stayman is being played, then the auction 1 – 1; 1NT – 2 would show this hand and end the auction. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walsh Transform
The Hadamard transform (also known as the Walsh–Hadamard transform, Hadamard–Rademacher–Walsh transform, Walsh transform, or Walsh–Fourier transform) is an example of a generalized class of Fourier transforms. It performs an orthogonal, symmetric, involutive, linear operation on real numbers (or complex, or hypercomplex numbers, although the Hadamard matrices themselves are purely real). The Hadamard transform can be regarded as being built out of size-2 discrete Fourier transforms (DFTs), and is in fact equivalent to a multidimensional DFT of size . It decomposes an arbitrary input vector into a superposition of Walsh functions. The transform is named for the French mathematician Jacques Hadamard (), the German-American mathematician Hans Rademacher, and the American mathematician Joseph L. Walsh. Definition The Hadamard transform ''H''''m'' is a 2''m'' × 2''m'' matrix, the Hadamard matrix (scaled by a normalization factor), that transforms 2''m'' re ...

Walsh Matrix
In mathematics, a Walsh matrix is a specific square matrix of dimensions 2, where ''n'' is some particular natural number. The entries of the matrix are either +1 or −1 and its rows as well as columns are orthogonal, i.e. dot product is zero. The Walsh matrix was proposed by Joseph L. Walsh in 1923. Each row of a Walsh matrix corresponds to a Walsh function. The Walsh matrices are a special case of Hadamard matrices. The ''naturally ordered'' Hadamard matrix is defined by the recursive formula below, and the ''sequency-ordered'' Hadamard matrix is formed by rearranging the rows so that the number of sign changes in a row is in increasing order. Confusingly, different sources refer to either matrix as the Walsh matrix. The Walsh matrix (and Walsh functions) are used in computing the Walsh transform and have applications in the efficient implementation of certain signal processing operations.

Walsh Function
In mathematics, more specifically in harmonic analysis, Walsh functions form a complete orthogonal set of functions that can be used to represent any discrete function—just like trigonometric functions can be used to represent any continuous function in Fourier analysis. They can thus be viewed as a discrete, digital counterpart of the continuous, analog system of trigonometric functions on the unit interval. But unlike the sine and cosine functions, which are continuous, Walsh functions are piecewise constant. They take the values −1 and +1 only, on sub-intervals defined by dyadic fractions. The system of Walsh functions is known as the Walsh system. It is an extension of the Rademacher system of orthogonal functions. Walsh functions, the Walsh system, the Walsh series, and the fast Walsh–Hadamard transform are all named after the American mathematician Joseph L. Walsh. They find various applications in physics and engineering when analyzing digital signals. Historical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Walsh (APD-111)
USS ''Walsh'' (APD-111) was a United States Navy ''Crosley''-class high-speed transport in commission from 1945 to 1946. She was scrapped in 1968. Namesake Patrick Joseph Walsh was born on 19 January 1908 in New York City. He accepted a commission in the United States Naval Reserve as a lieutenant, junior grade, on 4 May 1942. He received instruction at the Naval Training School, Boston, Massachusetts, and later received more specialized training at the Armed Guard School at Little Creek, Virginia, from 16 June 1942 to 22 July 1942. Walsh was Naval Armed Guard detachment commander aboard the merchant ship SS ''Patrick J. Hurley'' in the North Atlantic Ocean on the night of 12 September 1942 when the stealthily surfaced and closed on the ''Patrick J. Hurley''. Undetected, ''U-512'' opened fire on ''Patrick J. Hurley'' with devastating effect. Walsh fell severely wounded in the initial shelling, taking shrapnel in the throat. In spite of the machine-gun fire directed at his ba ...

Fort Walsh
Fort Walsh is a National Historic Sites of Canada, National Historic Site of Canada that was a North-West Mounted Police (NWMP) fort and the site of the Cypress Hills Massacre. Administered by Parks Canada, it forms a constituent part of Cypress Hills Interprovincial Park. The fort was built in June 1875 and was named for its builder, inspector James Morrow Walsh. The fort was intended to curb the illegal whiskey trade, protect Canada's nearby border with the United States, and aid with native policy. These factors had been brought to public attention following the Cypress Hills Massacre of 1873 and resulted in Prime Minister John A. Macdonald's establishment of the NWMP. Assiniboine chiefs Man Who Takes the Coat, Long Lodge, and Lean Man signed adhesion to Treaty 4 at the fort on September 25, 1877. Fort Walsh served as the NWMP headquarters from 1878 to 1882. In 1883 the fort was closed and dismantled. The site of the fort was designated a National Historic Sites of Canada, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
