Ulrich W. Kulisch
Ulrich W. Kulisch (born 1933 in Breslau) is a German mathematician specializing in numerical analysis, including the computer implementation of interval arithmetic. Experience After graduation from high school in Freising, Kulisch studied mathematics at the University of Munich and the Technical University of Munich where in 1961 he completed his dissertation (''Behandlung von Differentialgleichungen im Komplexen auf dem elektronischen Analogrechner'') under Josef Heinhold. After his postdoctoral qualification in 1963, he was acting Professor for Numerical Mathematics of the University of Munich from 1964 to 1966, and from 1966 Professor of Mathematics and Director of the Institute of Applied Mathematics at the University of Karlsruhe. During his time in academia, Kulisch spent several sabbaticals abroad. He spent time in 1969/1970 at the Mathematics Research Center of the University of Wisconsin–Madison under Ramon Edgar Moore; in 1972/1973 and 1978/1979 at IBM's Thomas J. ...

Pascal-XSC
Pascal is an Imperative programming, imperative and Procedural programming, procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structure, data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's variable (computer science), scalars and array data type, arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as list (abstract data type), lists, tree (data structure), trees and gr ...

Mathematics Genealogy Project
The Mathematics Genealogy Project (MGP) is a web-based database for the academic genealogy of mathematicians.. By 31 December 2021, it contained information on 274,575 mathematical scientists who contributed to research-level mathematics. For a typical mathematician, the project entry includes graduation year, thesis title (in its Mathematics Subject Classification), '' alma mater'', doctoral advisor, and doctoral students.. Origin of the database The project grew out of founder Harry Coonce's desire to know the name of his advisor's advisor.. Coonce was Professor of Mathematics at Minnesota State University, Mankato, at the time of the project's founding, and the project went online there in fall 1997.Mulcahy, Colm;The Mathematics Genealogy Project Comes of Age at Twenty-one(PDF) AMS Notices (May 2017) Coonce retired from Mankato in 1999, and in fall 2002 the university decided that it would no longer support the project. The project relocated at that time to North Dakota State U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibliographisches Institut
The German publishing company was founded 1826 in Gotha by Joseph Meyer, moved 1828 to Hildburghausen and 1874 to Leipzig. Its production over the years includes such well-known titles as ' (encyclopaedias, since 1839, see '), ' (animal life, 1863–1869, 4th ed. 1911–1918); ' (dictionaries on every aspect of the language, since 1880); ' (guide books, 1862–1936); ' (home and foreign literature); atlases (', '), newspapers (''Koloniale Zeitschrift'') and others. The buildings of the company were completely destroyed by the bombing raids on Leipzig 1943/1944; the company itself expropriated by the communist regime of East Germany in 1946 and turned into a '. The shareholders moved the company to Mannheim in West Germany in 1953 (). Titles like ', ', ' and ' appeared again. In Leipzig remained the , operating in the same field, publishing '", ' etc. In 1984 amalgamated with its biggest competitor in the market of reference works, of Wiesbaden to Bibliographisches Institu ...

Gesellschaft Für Angewandte Mathematik Und Mechanik
Gesellschaft für Angewandte Mathematik und Mechanik ("Society of Applied Mathematics and Mechanics"), often referred to by the acronym GAMM, is a German society for the promotion of science, founded in 1922 by the physicist Ludwig Prandtl and the mathematician Richard von Mises. The society awards the Richard von Mises prize annually. In 1958 the GAMM and the ACM together worked out the "ALGOL 58 Report" at a meeting in Zurich.

C-XSC
Interval arithmetic (also known as interval mathematics, interval analysis, or interval computation) is a mathematical technique used to put bounds on rounding errors and measurement errors in mathematical computation. Numerical methods using interval arithmetic can guarantee reliable and mathematically correct results. Instead of representing a value as a single number, interval arithmetic represents each value as a range of possibilities. For example, instead of saying the height of someone is approximately 2 meters, one could using interval arithmetic, say that the height of the person is definitely between 1.97 meters and 2.03 meters. Mathematically, using interval arithmetic, instead of working with an uncertain real-valued variable x, one works with an interval ,b/math> that defines the range of values that x can have. In other words, any value of the variable x lies in the closed interval between a and b. A function f, when applied to x, yields an inexact value; f ...
