K. D. Tocher
Keith Douglas "Toch" Tocher (19 March 1921 – 30 December 1981) was a computer scientist known for contributions to computer simulation. Tocher received a first-class BSc in Mathematics in 1941 from University College London, a BSc in Statistics in 1946 from University of London, and a PhD in 1952 at Imperial College London. In 1958, he worked for United Steel Companies under Anthony Stafford Beer, and developed the first discrete-event simulation package, the General Simulation Program (GSP), a program that used a common structure to execute a range of simulations. He was appointed professor of operational research at the University of Southampton in 1980. He was awarded the silver medal of the Operational Research Society The Operational Research Society (ORS), also known as The OR Society, is an international learned society in the field of operational research (OR), with more than 3,100 members (2021). It has its headquarters in Birmingham, England. History The ... in ...

Computer Simulation
Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering. Simulation of a system is represented as the running of the system's model. It can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions. Computer simulations are realized by running computer programs that can be either small, running almost instantly on small devices, or large ...

University Of London
The University of London (UoL; abbreviated as Lond or more rarely Londin in post-nominals) is a federal public research university located in London, England, United Kingdom. The university was established by royal charter in 1836 as a degree-awarding examination board for students holding certificates from University College London and King's College London and "other such other Institutions, corporate or unincorporated, as shall be established for the purpose of Education, whether within the Metropolis or elsewhere within our United Kingdom". This fact allows it to be one of three institutions to claim the title of the third-oldest university in England, and moved to a federal structure in 1900. It is now incorporated by its fourth (1863) royal charter and governed by the University of London Act 2018. It was the first university in the United Kingdom to introduce examinations for women in 1869 and, a decade later, the first to admit women to degrees. In 1913, it appointe ...

Imperial College London
Imperial College London (legally Imperial College of Science, Technology and Medicine) is a public research university in London, United Kingdom. Its history began with Prince Albert, consort of Queen Victoria, who developed his vision for a cultural area that included the Royal Albert Hall, Victoria & Albert Museum, Natural History Museum and royal colleges. In 1907, Imperial College was established by a royal charter, which unified the Royal College of Science, Royal School of Mines, and City and Guilds of London Institute. In 1988, the Imperial College School of Medicine was formed by merging with St Mary's Hospital Medical School. In 2004, Queen Elizabeth II opened the Imperial College Business School. Imperial focuses exclusively on science, technology, medicine, and business. The main campus is located in South Kensington, and there is an innovation campus in White City. Facilities also include teaching hospitals throughout London, and with Imperial College Healthcare ...

United Steel Companies
The United Steel Companies was a steelmaking, engineering, coal mining and coal by-product group based in South Yorkshire and Lincolnshire, England. History The company was registered in 1918 and the following year saw a joining together of steel makers Samuel Fox and Company of Stocksbridge; Steel, Peech and Tozer of Templeborough and Ickles in Rotherham; the Appleby-Frodingham Steel Company of Scunthorpe; and the coal mining and by-products interests of Rother Vale Collieries at Orgreave, Treeton and Thurcroft. Over the years other companies were added to the portfolio: The Sheffield Coal Company, owners of Birley Collieries, Brookhouse and North Staveley collieries, was bought by the United Steel Companies in 1937. This also included coal by-product operations at Orgreave and Brookhouse, suppliers of Metallurgical Coke for Blast Furnaces. The Kiveton Park Colliery Company was taken over in 1944 with reserves from, amongst others, the Barnsley seam being an attractiv ...

Division Algorithm
A division algorithm is an algorithm which, given two integers N and D, computes their quotient and/or remainder, the result of Euclidean division. Some are applied by hand, while others are employed by digital circuit designs and software. Division algorithms fall into two main categories: slow division and fast division. Slow division algorithms produce one digit of the final quotient per iteration. Examples of slow division include restoring, non-performing restoring, non-restoring, and SRT division. Fast division methods start with a close approximation to the final quotient and produce twice as many digits of the final quotient on each iteration. Newton–Raphson and Goldschmidt algorithms fall into this category. Variants of these algorithms allow using fast multiplication algorithms. It results that, for large integers, the computer time needed for a division is the same, up to a constant factor, as the time needed for a multiplication, whichever multiplication algorit ...
