Ryszard Syski
Ryszard Syski (April 8, 1924 in Płock, Poland - June 11, 2007 in Silver Spring, Maryland) was a Polish-American mathematician whose research was in queueing theory. During World War II he was in the Armia Krajowa with his parents, partaking in the Warsaw uprising, being imprisoned in Lamsdorf, Silesia and Bavaria (1944), and joining the Polish Second Corps for fights in Italy (1945). His studies in mathematics started in London, at the Polish University Abroad (1946). He joined ''Automatic Telephone and Electric Co.'' in London (1952). He got his B.Sc. (1954) and Ph.D. (1961) at University of London, on the dissertation ''Stochastic Process in Banach space and its Applications to Congestion Theory''. Encouraged by Thomas L. Saaty he moved to College Park, Maryland, joining the mathematics faculty of University of Maryland (1961–1999), founded the journal Stochastic Processes and their Applications (1973) and was fellow of the Institute of Mathematical Statistics.

Płock
Płock (pronounced ) is a city in central Poland, on the Vistula river, in the Masovian Voivodeship. According to the data provided by GUS on 31 December 2021, there were 116,962 inhabitants in the city. Its full ceremonial name, according to the preamble to the City Statute, is ''Stołeczne Książęce Miasto Płock'' (the Princely or Ducal Capital City of Płock). It is used in ceremonial documents as well as for preserving an old tradition. Płock is a capital of the ''powiat'' (county) in the west of the Masovian Voivodeship. From 1079 to 1138 it was the capital of Poland. The ''Wzgórze Tumskie'' ("Cathedral Hill") with the Płock Castle and the Catholic Cathedral, which contains the sarcophagi of a number of Polish monarchs, is listed as a Historic Monument of Poland. It was the main city and administrative center of Mazovia in the Middle Ages before the rise of Warsaw as a major city of Poland, and later it remained a royal city of Poland.Adolf Pawiński, ''Mazowsze'' ...

Polish Second Corps
The Polish II Corps ( pl, Drugi Korpus Wojska Polskiego), 1943–1947, was a major tactical and operational unit of the Polish Armed Forces in the West during World War II. It was commanded by Lieutenant General Władysław Anders and fought with distinction in the Italian Campaign, in particular at the Battle of Monte Cassino. By the end of 1945, the corps had grown to well over 100,000 soldiers. History Victims of Soviet deportations from occupied Poland in 1939–40 had been processed by the NKVD and sent to prison or exile in Siberia. The Nazi-Soviet pact of August 1939 effectively ended on 22 June 1941 when the German Wehrmacht invaded the USSR. The release of many thousands of former citizens of Poland (including Ukrainians and Belorussians) from the Soviet Gulags, following the signing of the Polish-Russian Military Agreement on 14 August 1941, allowed for the creation of a Polish Army on Soviet soil. Its first commander, General Michał Tokarzewski, began the task of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Markov Chain
A Markov chain or Markov process is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. Informally, this may be thought of as, "What happens next depends only on the state of affairs ''now''." A countably infinite sequence, in which the chain moves state at discrete time steps, gives a discrete-time Markov chain (DTMC). A continuous-time process is called a continuous-time Markov chain (CTMC). It is named after the Russian mathematician Andrey Markov. Markov chains have many applications as statistical models of real-world processes, such as studying cruise control systems in motor vehicles, queues or lines of customers arriving at an airport, currency exchange rates and animal population dynamics. Markov processes are the basis for general stochastic simulation methods known as Markov chain Monte Carlo, which are used for simulating sampling from complex probability dist ...

The Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Watergate scandal ...
