Joseph Slepian
Joseph Slepian (February 11, 1891 – December 19, 1969) was an American electrical engineer known for his contributions to the developments of electrical apparatus and theory. Born in Boston, MA of Jewish Russian immigrants, he studied mathematics at Harvard University, from which he was awarded a B.Sc. (1911), a M.Sc. (1912) and Ph.D. on the thesis ''On the Functions of a Complex Variable Defined by an Ordinary Differential Equation of the First Order and First Degree'' advised by George Birkhoff (1913). Meanwhile, he also worked at Boston Elevated Railway. After his Ph.D., he became Sheldon fellow at University of Göttingen in Germany, was at University of Sorbonne in Paris, before becoming instructor of mathematics at Cornell University (1915). He joined Westinghouse Electric in East Pittsburgh (1916) in the railway motor department initially, moving to the research department (1917) at Forest Hills (PA) where he became head (1922), consulting engineer (1926) and ...

Lightning Arrester
A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrester, in most cases to earth. In telegraphy and telephony, a lightning arrester is placed where wires enter a structure, preventing damage to electronic instruments within and ensuring the safety of individuals near them. Smaller versions of lightning arresters, also called surge arresters, are devices that are connected between each conductor in power and communications systems and the earth. These prevent ...

Institute Of Radio Engineers
The Institute of Radio Engineers (IRE) was a professional organization which existed from 1912 until December 31, 1962. On January 1, 1963, it merged with the American Institute of Electrical Engineers (AIEE) to form the Institute of Electrical and Electronics Engineers (IEEE). Founding Following several attempts to form a technical organization of wireless practitioners in 1908–1912, the Institute of Radio Engineers (IRE) was finally established in 1912 in New York City. Among its founding organizations were the Society of Wireless Telegraph Engineers (SWTE) and the Wireless Institute (TWI). At the time, the dominant organization of electrical engineers was the American Institute of Electrical Engineers (AIEE). Many of the founding members of IRE considered AIEE too conservative and too focused on electric power. Moreover, the founders of the IRE sought to establish an international organization (unlike the “American” AIEE), and adopted a tradition of electing some of ...

United States National Academy Of Sciences
The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve '' pro bono'' as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide scie ...

Officer De Academie
An officer is a person who has a position of authority in a hierarchical organization. The term derives from Old French ''oficier'' "officer, official" (early 14c., Modern French ''officier''), from Medieval Latin ''officiarius'' "an officer," from Latin ''officium'' "a service, a duty" the late Latin from ''officiarius'', meaning "official." Examples Ceremonial and other contexts *Officer, and/or Grand Officer, are both a grade, class, or rank of within certain chivalric orders and orders of merit, e.g. Legion of Honour (France), Order of the Holy Sepulchre (Holy See), Order of the British Empire ( UK), Order of Leopold (Belgium) *Great Officer of State *Merchant marine officer or licensed mariner *Officer of arms *Officer in The Salvation Army, and other state decorations Corporations *Bank officer *Corporate officer, a corporate title **Chief executive officer (CEO) **Chief financial officer (CFO) **Chief operating officer (COO) *Executive officer Education *Chief academic of ...

AIEE Lamme Medal
The initially called AIEE Lamme Medal was established in 1924 by the American Institute of Electrical Engineers (AIEE) to recognize members for 'meritorious achievement in the development of electrical apparatus or machinery.' The medal was named in recognition of Benjamin G. Lamme, Westinghouse' chief engineer, who amongst others was responsible for the construction of the Niagara Falls generators. The medal, established in accordance with Lamme's will, bears the inscription "The engineer views hopefully the hitherto unattainable." The medal continued to be awarded as the IEEE Lamme Medal by the board of directors of the Institute of Electrical and Electronics Engineers The Institute of Electrical and Electronics Engineers (IEEE) is a 501(c)(3) professional association for electronic engineering and electrical engineering (and associated disciplines) with its corporate office in New York City and its operation ...

John Scott Medal
John Scott Award, created in 1816 as the John Scott Legacy Medal and Premium, is presented to men and women whose inventions improved the "comfort, welfare, and happiness of human kind" in a significant way. "...the John Scott Medal Fund, established in 1816...". Since 1919 the Board of Directors of City Trusts of Philadelphia provide this award, recommended by an advisory committee. Eugene Garfield is member of the Advisory Committee. In 1822 the first awards were given to thirteen people by the Philadelphia Society for Promoting Agriculture entrusted by the " Corporation of the city of Philadelphia". The druggist John Scott of Edinburgh organized a $4,000 fund which, after his death in 1815 was administered by a merchant until the first award, a copper medal and "an amount not to exceed twenty dollars", was given in 1822. (At the time, $20 could buy one ox or a 12-volume encyclopedia.) Several hundred recipients have since been selected by the City Council of Philadelphia, whic ...

Stroke
A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control. The main risk factor for stroke is high blood pressure. Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-st ...
