David M. Young Jr.
David M. Young Jr. (October 20, 1923 – December 21, 2008) was an American mathematician and computer scientist who was one of the pioneers in the field of modern applied mathematics, numerical analysis/scientific computing. Contributions Dr. Young is best known for establishing the mathematical framework for iterative methods (a.k.a. preconditioner, preconditioning). These algorithms are now used in computer software on high performance supercomputers for the numerical solution of large Sparse matrix, sparse linear systems arising from problems involving partial differential equations. See, in particular, the successive over-relaxation (SOR) and symmetric successive over-relaxation (SSOR) methods.. When David Young first began his research on iterative methods in the late 1940s, there was some skepticism with the idea of using iterative methods on the new computing machines to solve industrial-size problems. Ever since Young's ground-breaking Ph.D. thesis, iterative methods have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quincy, Massachusetts
Quincy ( ) is a coastal U.S. city in Norfolk County, Massachusetts, United States. It is the largest city in the county and a part of Greater Boston, Metropolitan Boston as one of Boston's immediate southern suburbs. Its population in 2020 was 101,636, making it the seventh-largest city in the U.S. state, state. Known as the "City of Presidents", Quincy is the birthplace of two President of the United States, U.S. presidents—John Adams and his son John Quincy Adams—as well as John Hancock (a President of the Continental Congress and the first signer of the United States Declaration of Independence, Declaration of Independence) and the first and third Governor of Massachusetts. First settled in 1625, Quincy was briefly part of Dorchester, Boston, Dorchester before becoming the north precinct of Braintree, Massachusetts, Braintree in 1640. In 1792, Quincy was split off from Braintree; the new town was named after Colonel John Quincy, maternal grandfather of Abigail Adams and af ...

Iterative Methods
In computational mathematics, an iterative method is a mathematical procedure that uses an initial value to generate a sequence of improving approximate solutions for a class of problems, in which the ''n''-th approximation is derived from the previous ones. A specific implementation of an iterative method, including the termination criteria, is an algorithm of the iterative method. An iterative method is called convergent if the corresponding sequence converges for given initial approximations. A mathematically rigorous convergence analysis of an iterative method is usually performed; however, heuristic-based iterative methods are also common. In contrast, direct methods attempt to solve the problem by a finite sequence of operations. In the absence of rounding errors, direct methods would deliver an exact solution (for example, solving a linear system of equations A\mathbf=\mathbf by Gaussian elimination). Iterative methods are often the only choice for nonlinear equations. Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Society For Industrial And Applied Mathematics
Society for Industrial and Applied Mathematics (SIAM) is a professional society dedicated to applied mathematics, computational science, and data science through research, publications, and community. SIAM is the world's largest scientific society devoted to applied mathematics, and roughly two-thirds of its membership resides within the United States. Founded in 1951, the organization began holding annual national meetings in 1954, and now hosts conferences, publishes books and scholarly journals, and engages in advocacy in issues of interest to its membership. Members include engineers, scientists, and mathematicians, both those employed in academia and those working in industry. The society supports educational institutions promoting applied mathematics. SIAM is one of the four member organizations of the Joint Policy Board for Mathematics. Membership Membership is open to both individuals and organizations. By the end of its first full year of operation, SIAM had 130 memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard S
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below). People named Richard Multiple people with the same name * Richard Andersen (other) * Richard Anderson (other) * Richard Cartwright (other) * Ri ...

Fellow
A fellow is a concept whose exact meaning depends on context. In learned or professional societies, it refers to a privileged member who is specially elected in recognition of their work and achievements. Within the context of higher educational institutions, a fellow can be a member of a highly ranked group of teachers at a particular college or university or a member of the governing body in some universities (such as the Fellows of Harvard College); it can also be a specially selected postgraduate student who has been appointed to a post (called a fellowship) granting a stipend, research facilities and other privileges for a fixed period (usually one year or more) in order to undertake some advanced study or research, often in return for teaching services. In the context of research and development-intensive large companies or corporations, the title "fellow" is sometimes given to a small number of senior scientists and engineers. In the context of medical education in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
