Occupational Surname
In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community. Practices vary by culture. The family name may be placed at either the start of a person's full name, as the forename, or at the end; the number of surnames given to an individual also varies. As the surname indicates genetic inheritance, all members of a family unit may have identical surnames or there may be variations; for example, a woman might marry and have a child, but later remarry and have another child by a different father, and as such both children could have different surnames. It is common to see two or more words in a surname, such as in compound surnames. Compound surnames can be composed of separate names, such as in traditional Spanish culture, they can be hyphenated together, or may contain prefixes. Using names has been documented in even the oldest historical records. Examples of surnames are documented in the 11th ce ...

Joseph Rademacher (soldier)
''Brothers at War'' is a 2009 documentary film directed by Jake Rademacher and produced by Rademacher and Norman S. Powell. The film follows several US soldiers in the Iraq War. The film's executive producers are actor, director, and Presidential Citizens Medal recipient Gary Sinise and Secretary of Defense Medal for Outstanding Public Service recipient David Scantling. ''Brothers at War'' won the Best Documentary Feature Award at the 2008 GI Film Festival. The film features an original score by Lee Holdridge and an original song--"Brothers in Arms"—by John Ondrasik of Five for Fighting. Synopsis Filmmaker Jake Rademacher sets out to understand the motivation, sacrifice and experience of his two younger brothers, Isaac and Joe, serving in Iraq. The film depicts the toll the life-threatening work and separation take on the parents, siblings, wives and children of the soldiers. As the film develops, however, it becomes clear that an underlying motivation for Jake is to prove h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rademacher's Theorem
In mathematical analysis, Rademacher's theorem, named after Hans Rademacher, states the following: If is an open subset of and is Lipschitz continuous, then is differentiable almost everywhere in ; that is, the points in at which is ''not'' differentiable form a set of Lebesgue measure zero. Differentiability here refers to infinitesimal approximability by a linear map, which in particular asserts the existence of the coordinate-wise partial derivatives. Sketch of proof The one-dimensional case of Rademacher's theorem is a standard result in introductory texts on measure-theoretic analysis. In this context, it is natural to prove the more general statement that any single-variable function of bounded variation is differentiable almost everywhere. (This one-dimensional generalization of Rademacher's theorem fails to extend to higher dimensions.) One of the standard proofs of the general Rademacher theorem was found by Charles Morrey. In the following, let denote a Lipschitz-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rademacher Distribution
In probability theory and statistics, the Rademacher distribution (which is named after Hans Rademacher) is a discrete probability distribution where a random variate ''X'' has a 50% chance of being +1 and a 50% chance of being -1. A series (that is, a sum) of Rademacher distributed variables can be regarded as a simple symmetrical random walk where the step size is 1. Mathematical formulation The probability mass function of this distribution is : f(k) = \left\{\begin{matrix} 1/2 & \mbox {if }k=-1, \\ 1/2 & \mbox {if }k=+1, \\ 0 & \mbox {otherwise.}\end{matrix}\right. In terms of the Dirac delta function, as : f( k ) = \frac{ 1 }{ 2 } \left( \delta \left( k - 1 \right) + \delta \left( k + 1 \right) \right). Bounds on sums of independent Rademacher variables There are various results in probability theory around analyzing the sum of i.i.d. Rademacher variables, including concentration inequalities such as Bernstein inequalities as well as anti-concentration inequalit ...

Rademacher Complexity
In computational learning theory (machine learning and theory of computation), Rademacher complexity, named after Hans Rademacher, measures richness of a class of real-valued functions with respect to a probability distribution. Definitions Rademacher complexity of a set Given a set A\subseteq \mathbb^m, the Rademacher complexity of ''A'' is defined as follows:Chapter 26 in : \operatorname(A) := \frac \mathbb_\sigma \left \sup_ \sum_^m \sigma_i a_i \right where \sigma_1, \sigma_2, \dots, \sigma_m are independent random variables drawn from the Rademacher distribution i.e. \Pr(\sigma_i = +1) = \Pr(\sigma_i = -1) = 1/2 for i=1,2,\dots,m, and a=(a_1, \ldots, a_m). Some authors take the absolute value of the sum before taking the supremum, but if A is symmetric this makes no difference. Rademacher complexity of a function class Let S=(z_1, z_2, \dots, z_m) \in Z^m be a sample of points and consider a function class \mathcal of real-valued functions over Z^m. Then, ...

House Of Rademacher
Rademacher is a Rhenish family of ancient nobility, that has its roots in the village of Rodemack in Lorraine. They also settled in Middelburg, Netherlands and in the latter also in North Rhine-Westphalia (Aachen), East Prussia (Tilsit), Latvia (Riga) and Hesse (Frankfurt). History Ancestry The genealogical tree of the House of Rademacher leads back to the noble family ''de Rodemack'' from the village of Rodemack in Lorraine. The first document alluding the House of Rademacher from 1264 names the Rademacher coat of arms. On July 13, 1549 Charles V. awarded a patent of nobility to the House of Rademacher, only accrediting the already existing state of nobility. Family tree The first known locum of the dynasty was Dipoldus de Rodemack, who was born in 904. In the 11th to 12th century the name changed to von Rodemack, von Rodemacker and then von Rademacker. But the actual name ''von Rademacher'' was already in use in the 13th century. As a Templar Matthias Ă„gidius von Rademacher ...

Rudolf Rademacher
Rudolf "Rudi" Rademacher (19 June 1913 – 13 June 1953) was a German military aviator who served in the Luftwaffe during World War II. As a fighter ace, he was credited with 97, potentially up to 126, aerial victories—that is, 97 aerial combat encounters resulting in the destruction of the enemy aircraft—claimed in over 500 combat missions. The majority of his victories were claimed over the Eastern Front, with sixteen claims over the Western Front, all of which were achieved while flying the Messerschmitt Me 262 jet fighter. Rademacher was born on 19 June 1913 in Lüneburg, Province of Hanover, a province of the Kingdom of Prussia. He served in the Luftwaffe of Nazi Germany. Following flight training, he was posted to ''Jagdgeschwader'' 54 (JG 54—54th Fighter Wing) in 1941, operating on the Eastern Front. He claimed his first aerial victory on 9 January 1942. In March 1943, Rademacher joined ''Schwarm'', flight of four aircraft, headed by Walter Nowotny, the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pete Rademacher
Thomas Peter Rademacher (November 20, 1928 – June 4, 2020) was an American heavyweight boxer. A gold medalist at the 1956 Olympics, he became the only person to challenge for the world heavyweight championship in his first professional bout when he faced Floyd Patterson in Seattle on August 22, 1957. He compiled a 15-8-1 record over 23 professional bouts. A former college football player at Washington State, Rademacher took up boxing as a form of rehabilitation during his recovery from rheumatic fever, which he contracted in military school. Amateur career In his amateur career, Rademacher won 72 bouts and lost 7. He won a series of tournaments, including the 1949 and 1951–1953 Seattle Golden Gloves (he lost in 1950 to Zora Folley, who was his frequent opponent throughout his boxing career), and the US Amateur Championship as a heavyweight in 1953—avenging his earlier loss to Folley. He captured the Chicago Golden Gloves, the All-Army championship, and the Serv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
