Numerical Linear Algebra
Numerical linear algebra, sometimes called applied linear algebra, is the study of how matrix operations can be used to create computer algorithms which efficiently and accurately provide approximate answers to questions in continuous mathematics. It is a subfield of numerical analysis, and a type of linear algebra. Computers use floating-point arithmetic and cannot exactly represent irrational data, so when a computer algorithm is applied to a matrix of data, it can sometimes increase the difference between a number stored in the computer and the true number that it is an approximation of. Numerical linear algebra uses properties of vectors and matrices to develop computer algorithms that minimize the error introduced by the computer, and is also concerned with ensuring that the algorithm is as efficient as possible. Numerical linear algebra aims to solve problems of continuous mathematics using finite precision computers, so its applications to the natural and social sciences ar ...

SIAM Journal On Matrix Analysis And Applications
The ''SIAM Journal on Matrix Analysis and Applications'' (until 1989: ''SIAM Journal on Algebraic and Discrete Methods'') is a peer-reviewed scientific journal covering matrix analysis and its applications. The relevant applications include signal processing, systems and control theory, statistics, Markov chains, mathematical biology, graph theory, and data science. The journal is published by the Society for Industrial and Applied Mathematics. The founding editor-in-chief was Gene H. Golub, who established the journal in 1980. The current editor is Michele Benzi (Scuola Normale Superiore).

Editor In Chief
An editor-in-chief (EIC), also known as lead editor or chief editor, is a publication's editorial leader who has final responsibility for its operations and policies. The highest-ranking editor of a publication may also be titled editor, managing editor, or executive editor, but where these titles are held while someone else is editor-in-chief, the editor-in-chief outranks the others. Description The editor-in-chief heads all departments of the organization and is held accountable for delegating tasks to staff members and managing them. The term is often used at newspapers, magazines, yearbooks, and television news programs. The editor-in-chief is commonly the link between the publisher or proprietor and the editorial staff. The term is also applied to academic journals, where the editor-in-chief gives the ultimate decision whether a submitted manuscript will be published. This decision is made by the editor-in-chief after seeking input from reviewers selected on the basis of re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Candler Dobbs
Samuel Candler Dobbs (November 8, 1868 – October 31, 1950) was president (1919-1920) and chairman of The Coca-Cola Company, from 1919 to 1922. Early life and education Dobbs was born in 1868 in Georgia. He was the son of Harris Henry Dobbs, and cousin of Asa Griggs Candler, founder of The Coca-Cola Company. Career Dobbs began his career as an Atlanta-based Coca-Cola salesman, during which he persuaded Joe Biedenharn of the ''Biedenharn Candy Company'' to set up a Coca-Cola dispenser in this store and order the beverage on a regular basis, thereby fueling sales and recognition of the Coca-Cola name. Dobbs later became the company's sales manager and president. In 1909, Dobbs became president of the Associated Advertising Clubs of America, now the American Advertising Federation (AAF), and began to make speeches on the subject. Philanthropy and legacy In January 1939, Dobbs made a $1,000,000 unrestricted gift to the Emory University. Several endowed chair A financial endowmen ...

Endowed Chair
A financial endowment is a legal structure for managing, and in many cases indefinitely perpetuating, a pool of financial, real estate, or other investments for a specific purpose according to the will of its founders and donors. Endowments are often structured so that the inflation-adjusted principal or "corpus" value is kept intact, while a portion of the fund can be (and in some cases must be) spent each year, utilizing a prudent spending policy. Endowments are often governed and managed either as a nonprofit corporation, a charitable foundation, or a private foundation that, while serving a good cause, might not qualify as a public charity. In some jurisdictions, it is common for endowed funds to be established as a trust independent of the organizations and the causes the endowment is meant to serve. Institutions that commonly manage endowments include academic institutions (e.g., colleges, universities, and private schools); cultural institutions (e.g., museums, libraries, ...

Los Alamos National Laboratory
Los Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.The site was variously called Los Alamos Laboratory and Los Alamos Scientific Laboratory. Chosen for its remote yet relatively accessible location, it served as the main hub for conducting and coordinating nuclear research, bringing together some of the world's most famous scientists, among them numerous Nobel Prize winners. The town of Los Alamos, directly north of the lab, grew extensively through this period. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preconditioners
In mathematics, preconditioning is the application of a transformation, called the preconditioner, that conditions a given problem into a form that is more suitable for numerical solving methods. Preconditioning is typically related to reducing a condition number of the problem. The preconditioned problem is then usually solved by an iterative method. Preconditioning for linear systems In linear algebra and numerical analysis, a preconditioner P of a matrix A is a matrix such that P^A has a smaller condition number than A. It is also common to call T=P^ the preconditioner, rather than P, since P itself is rarely explicitly available. In modern preconditioning, the application of T=P^, i.e., multiplication of a column vector, or a block of column vectors, by T=P^, is commonly performed in a matrix-free fashion, i.e., where neither P, nor T=P^ (and often not even A) are explicitly available in a matrix form. Preconditioners are useful in iterative methods to solve a linear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Systems
In systems theory, a linear system is a mathematical model of a system based on the use of a linear operator. Linear systems typically exhibit features and properties that are much simpler than the nonlinear case. As a mathematical abstraction or idealization, linear systems find important applications in automatic control theory, signal processing, and telecommunications. For example, the propagation medium for wireless communication systems can often be modeled by linear systems. Definition A general deterministic system can be described by an operator, that maps an input, as a function of to an output, a type of black box description. A system is linear if and only if it satisfies the superposition principle, or equivalently both the additivity and homogeneity properties, without restrictions (that is, for all inputs, all scaling constants and all time.) The superposition principle means that a linear combination of inputs to the system produces a linear combination ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
