Klaus Matthes
Klaus Matthes (January 20, 1931 – March 9, 1998) was a German mathematician, known as the founder of the theory of marked and infinitely divisible point processes. From 1981 to 1991 he was the director of the GDR Academy of Sciences' Institute of Mathematics in Berlin. Early years Matthes studied from 1948 to 1954 mathematics at Humboldt University of Berlin. He obtained his PhD from his alma mater in 1958, advised by Heinrich Grell and Kurt Schröder. In 1963 he received the habilitation, with Willi Rinow as one of the referees.

Probability Theorists
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty."Kendall's Advanced Theory of Statistics, Volume 1: Distribution Theory", Alan Stuart and Keith Ord, 6th Ed, (2009), .William Feller, ''An Introduction to Probability Theory and Its Applications'', (Vol 1), 3rd Ed, (1968), Wiley, . The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%). These conce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sanssouci
Sanssouci () is a historical building in Potsdam, near Berlin. Built by Prussian King Frederick the Great as his summer palace, it is often counted among the German rivals of Versailles. While Sanssouci is in the more intimate Rococo style and is far smaller than its French Baroque counterpart, it, too, is notable for the numerous temples and follies in the surrounding park. The palace was designed and built by Georg Wenzeslaus von Knobelsdorff between 1745 and 1747 to meet Frederick's need for a private residence where he could escape the pomp and ceremony of the royal court. The palace's name is a French phrase (''sans souci'') that translates as "without concerns", meaning "without worries" or "carefree", emphasising that the palace was meant as a place of relaxation, rather than a seat of power. Sanssouci is little more than a large, single-story villa—more like the Château de Marly than Versailles. Containing just ten principal rooms, it was built on the brow of a ter ...

Boris Vladimirovich Gnedenko
Boris Vladimirovich Gnedenko (russian: Бори́с Влади́мирович Гнеде́нко; January 1, 1912 – December 27, 1995) was a Soviet Ukrainian mathematician and a student of Andrey Kolmogorov. He was born in Simbirsk (now Ulyanovsk), Russia, and died in Moscow. He is perhaps best known for his work with Kolmogorov, and his contributions to the study of probability theory, particularly extreme value theory, with such results as the Fisher–Tippett–Gnedenko theorem. Gnedenko was appointed as Head of the Physics, Mathematics and Chemistry Section of the Ukrainian Academy of Sciences in 1949, and became Director of the NASU Institute of Mathematics in 1955. Gnedenko was a leading member of the Russian school of probability theory and statistics. He also worked on applications of statistics to reliability and quality control in manufacturing. He wrote a history of mathematics in Russia (published 1946) and with O. B. Sheynin the section on the history of probability ...

Stochastic Geometry
In mathematics, stochastic geometry is the study of random spatial patterns. At the heart of the subject lies the study of random point patterns. This leads to the theory of spatial point processes, hence notions of Palm conditioning, which extend to the more abstract setting of random measures. Models There are various models for point processes, typically based on but going beyond the classic homogeneous Poisson point process (the basic model for ''complete spatial randomness'') to find expressive models which allow effective statistical methods. The point pattern theory provides a major building block for generation of random object processes, allowing construction of elaborate random spatial patterns. The simplest version, the Boolean model, places a random compact object at each point of a Poisson point process. More complex versions allow interactions based in various ways on the geometry of objects. Different directions of application include: the production of models ...

Branching Process
In probability theory, a branching process is a type of mathematical object known as a stochastic process, which consists of collections of random variables. The random variables of a stochastic process are indexed by the natural numbers. The original purpose of branching processes was to serve as a mathematical model of a population in which each individual in generation n produces some random number of individuals in generation n+1, according, in the simplest case, to a fixed probability distribution that does not vary from individual to individual. Branching processes are used to model reproduction; for example, the individuals might correspond to bacteria, each of which generates 0, 1, or 2 offspring with some probability in a single time unit. Branching processes can also be used to model other systems with similar dynamics, e.g., the spread of surnames in genealogy or the propagation of neutrons in a nuclear reactor. A central question in the the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queueing Theory
Queueing theory is the mathematical study of waiting lines, or queues. A queueing model is constructed so that queue lengths and waiting time can be predicted. Queueing theory is generally considered a branch of operations research because the results are often used when making business decisions about the resources needed to provide a service. Queueing theory has its origins in research by Agner Krarup Erlang when he created models to describe the system of Copenhagen Telephone Exchange company, a Danish company. The ideas have since seen applications including telecommunication, traffic engineering, computing and, particularly in industrial engineering, in the design of factories, shops, offices and hospitals, as well as in project management. Spelling The spelling "queueing" over "queuing" is typically encountered in the academic research field. In fact, one of the flagship journals of the field is ''Queueing Systems''.
