Rudolf Schauffler
Rudolf Schauffler (born 11 August 1889 in Ulm– died 6 February 1968) was a German mathematician, who was most notable for being the nominal head of the Linguistics and Cryptanalysis section of Pers Z S, the Signal Intelligence Agency of the German Foreign Office () before and during World War II. Life Before World War I Schauffler had been a schoolmaster after studying mathematics, physics and languages at the University of Tübingen and the Ludwig Maximilian University of Munich. During World War I he was gassed. During the first world war, Schauffler worked as a cryptanalyst at the German army headquarters. After the war Schauffler found the work of schoolmaster to be too difficult and decided to join Pers Z S. Schauffler was recruited by Kurt Selchow and joined on the 1 December 1918. Selchow who also recruited Werner Kunze, Adolf Paschke, Karl Zastrow, Wilhelm Brandes, and Ernst Hoffmann for the unit as he had known them during the war. Although he did not have a ...

Linguistics
Linguistics is the scientific study of human language. It is called a scientific study because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language, particularly its nature and structure. Linguistics is concerned with both the cognitive and social aspects of language. It is considered a scientific field as well as an academic discipline; it has been classified as a social science, natural science, cognitive science,Thagard, PaulCognitive Science, The Stanford Encyclopedia of Philosophy (Fall 2008 Edition), Edward N. Zalta (ed.). or part of the humanities. Traditional areas of linguistic analysis correspond to phenomena found in human linguistic systems, such as syntax (rules governing the structure of sentences); semantics (meaning); morphology (structure of words); phonetics (speech sounds and equivalent gestures in sign languages); phonology (the abstract sound system of a particular language); and pragmatics (how social con ...

Check Digit
A check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data. It consists of one or more digits (or letters) computed by an algorithm from the other digits (or letters) in the sequence input. With a check digit, one can detect simple errors in the input of a series of characters (usually digits) such as a single mistyped digit or some permutations of two successive digits. Design Check digit algorithms are generally designed to capture ''human'' transcription errors. In order of complexity, these include the following: * letter/digit errors, such as l → 1 or O → 0 * single-digit errors, such as 1 → 2 * transposition errors, such as 12 → 21 * twin errors, such as 11 → 22 * jump transpositions errors, such as 132 → 231 * jump twi ...

West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The FRG's provisional capital was the city of Bonn, and the Cold War era country is retrospectively designated as the Bonn Republic. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camp King
Camp King is a site on the outskirts of Oberursel, Taunus (in Germany), with a long history. It began as a school for agriculture under the auspices of the University of Frankfurt. During World War II, the lower fields became an interrogation center for the German Air Force. After World War II, the United States Army also used it as an interrogation center and intelligence post. The United States CIA used the site to test drugs including LSD on prisoners as part of Project BLUEBIRD, the predecessor to MKUltra. In 1968, it became the command and control center for the United States Army Movements Control Agency - Europe ( USAMCAEUR). Today it has been rebuilt as a German housing area. History Prior to World War II (1926–1939) Prior to World War II, what later became known as Auswertstelle West during World War II, was an educational farm established, in 1936, under the auspices of the University of Frankfurt. Students learned gardening, bee keeping, animal husbandry as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinz Kuntze
The H. J. Heinz Company is an American food processing company headquartered at One PPG Place in Pittsburgh, Pennsylvania. The company was founded by Henry J. Heinz in 1869. Heinz manufactures thousands of food products in plants on six continents, and markets these products in more than 200 countries and territories. The company claims to have 150 number-one or number-two brands worldwide. Heinz ranked first in ketchup in the US with a market share in excess of 50%; the Ore-Ida label held 46% of the frozen potato sector in 2003. Since 1896, the company has used its "57 Varieties" slogan; it was inspired by a sign advertising 21 styles of shoes, and Henry Heinz chose the number 57 even though the company manufactured more than 60 products at the time, because "5" was his lucky number and "7" was his wife's. In February 2013, Heinz agreed to be purchased by Berkshire Hathaway and the Brazilian investment firm 3G Capital for $23billion. On March 25, 2015, Kraft announced its ...

Basic Research
Basic research, also called pure research or fundamental research, is a type of scientific research with the aim of improving scientific theories for better understanding and prediction of natural or other phenomena. In contrast, applied research uses scientific theories to develop technology or techniques which can be used to intervene and ''alter'' natural or other phenomena.

Emil Krebs
Emil Krebs (15 November 1867 in Freiburg in Schlesien – 31 March 1930 in Berlin) was a German polyglot and sinologist. He mastered 69 languages in speech and writing and studied 120 other languages.Cecile und Oskar Vogt Archiv, Düsseldorf, Interview Dr. Zwirner/Mande Krebs im Hirnforschungszentrum Berlin-Buch 1930; Nachruf Prof. Dr. Eduard Erkes, Litterae Orientales 1931, S. 13 und 14 Life Early life Born in Freiburg in Silesia, Germany (now Świebodzice, Poland) on 15 November 1867, Emil Krebs was the son of a master carpenter named Gottlob Krebs and his wife Pauline Scholz. In 1870 he moved with his parents to Esdorf, where he attended primary school. From 1878 to 1880 he attended the Freiburger Realschule (secondary school), and from 1880 to 1887 he studied at the gymnasium in Schweidnitz. The curriculum included Latin, French, Hebrew and Classical Greek, but in addition he studied Modern Greek, English, Italian and later Spanish, Russian, Polish, Arabic and Turkish. ...

Japanese Language
is spoken natively by about 128 million people, primarily by Japanese people and primarily in Japan, the only country where it is the national language. Japanese belongs to the Japonic or Japanese- Ryukyuan language family. There have been many attempts to group the Japonic languages with other families such as the Ainu, Austroasiatic, Koreanic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), there was a massive influx of Sino-Japanese vocabulary into the language, affecting the phonology of Early Middle Japanese. Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords. The basis of the standard dialect moved f ...

Chinese Language
Chinese (, especially when referring to written Chinese) is a group of languages spoken natively by the ethnic Han Chinese majority and many minority ethnic groups in Greater China. About 1.3 billion people (or approximately 16% of the world's population) speak a variety of Chinese as their first language. Chinese languages form the Sinitic branch of the Sino-Tibetan languages family. The spoken varieties of Chinese are usually considered by native speakers to be variants of a single language. However, their lack of mutual intelligibility means they are sometimes considered separate languages in a family. Investigation of the historical relationships among the varieties of Chinese is ongoing. Currently, most classifications posit 7 to 13 main regional groups based on phonetic developments from Middle Chinese, of which the most spoken by far is Mandarin (with about 800 million speakers, or 66%), followed by Min (75 million, e.g. Southern Min), Wu (74 million, e.g. Shangh ...

One-time Pad
In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this technique, a plaintext is paired with a random secret key (also referred to as ''a one-time pad''). Then, each bit or character of the plaintext is encrypted by combining it with the corresponding bit or character from the pad using modular addition. The resulting ciphertext will be impossible to decrypt or break if the following four conditions are met: #The key must be at least as long as the plaintext. #The key must be random ( uniformly distributed in the set of all possible keys and independent of the plaintext), entirely sampled from a non-algorithmic, chaotic source such as a hardware random number generator. It is not sufficient for OTP keys to pass statistical randomness tests as such tests cannot measure entropy, and the number of bits of entropy must be at least equa ...
