Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The Regions of the African Union, African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shady Side Academy
} Shady Side Academy is an independent preparatory school located in the Borough of Fox Chapel (suburban Pittsburgh), and in the Point Breeze neighborhood of Pittsburgh, Pennsylvania. Founded in 1883 as an all-male night school in the Shadyside neighborhood of Pittsburgh, the academy now offers a secular coeducational PK–12 program on four campuses in the city and its suburbs, including a boarding program in the Croft and Morewood Houses of its Senior School Campus. Formed to provide for the education of the sons of newly moneyed industrialists of Pittsburgh's East End, the academy counts the Frick and Mellon families among its early patrons. In 1922 the academy expanded to its sprawling Georgian Senior School campus in the then-countryside of Fox Chapel under the influence of the Country Day School movement. The academy merged with the Arnold School in 1940 to form its Junior School campus and added its stone Tudor manor-style Middle School campus in 1958, emerging in its ...

SubStation Alpha
SubStation Alpha (or Sub Station Alpha), abbreviated SSA, is a Subtitle (captioning), subtitle file format created by CS Low (also known as Kotus) that allows for more advanced subtitles than the conventional SubRip, SRT and similar formats. It is also the name of the popular, now discontinued tool used to edit subtitles. This subtitle format is frequently used in anime fansubs, either to overlay subtitles onto video while it is being encoded (hardsubbing), or to store subtitle data alongside video data, often in a Matroska (MKV) container (softsubbing). It's not commonly used professionally except by Crunchyroll. The current version of SSA is v4.00. There are many #Software support, freeware and open source subtitling applications that support the SSA format.

Strong Subadditivity Of Quantum Entropy
In quantum information theory, strong subadditivity of quantum entropy (SSA) is the relation among the von Neumann entropies of various quantum subsystems of a larger quantum system consisting of three subsystems (or of one quantum system with three degrees of freedom). It is a basic theorem in modern quantum information theory. It was conjectured by D. W. Robinson and D. Ruelle in 1966 and O. E. Lanford III and D. W. Robinson in 1968 and proved in 1973 by E.H. Lieb and M.B. Ruskai, building on results obtained by Lieb in his proof of the Wigner-Yanase-Dyson conjecture. The classical version of SSA was long known and appreciated in classical probability theory and information theory. The proof of this relation in the classical case is quite easy, but the quantum case is difficult because of the non-commutativity of the reduced density matrices describing the quantum subsystems. Some useful references here include: *"Quantum Computation and Quantum Information" *"Quantum Entr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gillespie Algorithm
In probability theory, the Gillespie algorithm (or the Doob-Gillespie algorithm or ''Stochastic Simulation Algorithm'', the SSA) generates a statistically correct trajectory (possible solution) of a stochastic equation system for which the reaction rates are known. It was created by Joseph L. Doob and others (circa 1945), presented by Dan Gillespie in 1976, and popularized in 1977 in a paper where he uses it to simulate chemical or biochemical systems of reactions efficiently and accurately using limited computational power (see stochastic simulation). As computers have become faster, the algorithm has been used to simulate increasingly complex systems. The algorithm is particularly useful for simulating reactions within cells, where the number of reagents is low and keeping track of the position and behaviour of individual molecules is computationally feasible. Mathematically, it is a variant of a dynamic Monte Carlo method and similar to the kinetic Monte Carlo methods. It is used h ...

Static Single-assignment Form
In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a property of an intermediate representation (IR) that requires each variable to be assigned exactly once and defined before it is used. Existing variables in the original IR are split into ''versions'', new variables typically indicated by the original name with a subscript in textbooks, so that every definition gets its own version. In SSA form, use-def chains are explicit and each contains a single element. SSA was proposed by Barry K. Rosen, Mark N. Wegman, and F. Kenneth Zadeck in 1988. Ron Cytron, Jeanne Ferrante and the previous three researchers at IBM developed an algorithm that can compute the SSA form efficiently. One can expect to find SSA in a compiler for Fortran, C or C++, whereas in functional language compilers, such as those for Scheme and ML, continuation-passing style (CPS) is generally used. SSA is formally equivalent to a well-behaved subset of CPS excludi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serial Storage Architecture
Serial Storage Architecture (SSA) was a serial transport protocol used to attach disk drives to server computers. History SSA was invented by Ian Judd of IBM in 1990. IBM produced a number of successful products based upon this standard before it was overtaken by the more widely adopted Fibre Channel protocol. SSA was promoted as an open standard by the SSA Industry Association, unlike its predecessor the first generation Serial Disk Subsystem. A number of vendors including IBM, Pathlight Technology and Vicom Systems produced products based on SSA. It was also adopted as an American National Standards Institute (ANSI) X3T10.1 standard. SSA devices are logically SCSI devices and conform to all of the SCSI command protocols. SSA provides data protection for critical applications by helping to ensure that a single cable failure will not prevent access to data. All the components in a typical SSA subsystem are connected by bi-directional cabling. Data sent from the adaptor can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodrow Wilson
Thomas Woodrow Wilson (December 28, 1856February 3, 1924) was an American politician and academic who served as the 28th president of the United States from 1913 to 1921. A member of the Democratic Party, Wilson served as the president of Princeton University and as the governor of New Jersey before winning the 1912 presidential election. As president, Wilson changed the nation's economic policies and led the United States into World War I in 1917. He was the leading architect of the League of Nations, and his progressive stance on foreign policy came to be known as Wilsonianism. Wilson grew up in the American South, mainly in Augusta, Georgia, during the Civil War and Reconstruction. After earning a Ph.D. in political science from Johns Hopkins University, Wilson taught at various colleges before becoming the president of Princeton University and a spokesman for progressivism in higher education. As governor of New Jersey from 1911 to 1913, Wilson broke with party bosse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selective Service Act Of 1917
The Selective Service Act of 1917 or Selective Draft Act () authorized the United States federal government to raise a national army for service in World War I through conscription. It was envisioned in December 1916 and brought to President Woodrow Wilson's attention shortly after the break in relations with Germany in February 1917. The Act itself was drafted by then-Captain (later Brigadier General) Hugh S. Johnson after the United States entered World War I by declaring war on Germany. The Act was canceled with the end of the war on November 11, 1918. The Act was upheld as constitutional by the United States Supreme Court in 1918. History Origins At the time of World War I, the US Army was small compared with the mobilized armies of the European powers. As late as 1914, the Regular Army had under 100,000 men, while the National Guard (the organized militias of the states) numbered around 115,000. The National Defense Act of 1916 authorized the growth of the Army to 165,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
