Cedergren Medal
The Cedergren Medal is a rarely granted honor awarded to outstanding scientists in electrical engineering by the Cedergren Foundation. Only 14 have been issued since the recognition was created in 1914. Mathematics genius and electrical engineering pioneer Charles P. Steinmetz was the first recipient of the honor's silver medal. The award is administered on behalf of the foundation by the KTH - Royal Institute of Technology, one of Europe's leading technical and engineering universities. In addition to funding the honor, the foundation, which was established in 1909, also uses its endowment fund's investment returns for scholarships to Swedish electro technicians. Namesake Henrik Tore Cedergren (1853-1909) was the founder of Stockholms Allmänna Telefon AB which merged with Lars Magnus Ericsson’s company in 1918 to become Allmänna Telefonaktiebolaget L M Ericsson. Today, Ericsson is the world’s largest mobile communication network provider, holding 35% market share. Part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and ele ...

Charles P
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its dep ...

KTH - Royal Institute Of Technology
The KTH Royal Institute of Technology ( sv, Kungliga Tekniska högskolan, lit=Royal Institute of Technology), abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm. KTH was established in 1827 as the ''Teknologiska institutet (Institute of Technology)'' and had its roots in the ''Mekaniska skolan (School of Mechanics)'' that was established in 1798 in Stockholm. But the origin of KTH dates back to the predecessor of the ''Mekaniska skolan'', the ''Laboratorium mechanicum'', which was established in 1697 by the Swedish scientist and innovator Christopher Polhem. The Laboratorium mechanicum combined education technology, a laboratory, and an exhibition space for innovations. In 1877 KTH received its current name, Kungliga Tekniska högskolan (KTH Royal Institute of Tech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lars Magnus Ericsson
Lars Magnus Ericsson (; 5 May 1846 – 17 December 1926) was a Swedish inventor, entrepreneur and founder of telephone equipment manufacturer Ericsson ( incorporated as ''Telefonaktiebolaget LM Ericsson''). Lars Magnus was born in Värmskog, Värmland, and grew up in the small village of Vegerbol located between Karlstad and Arvika. At the age of 12, Ericsson's father died forcing him to seek work as a miner. He worked until he had enough money to leave the village and move to Stockholm in 1867. He then worked for six years for an instrument maker named ''Öllers & Co.'' who mainly created telegraph equipment. Because of his skills, he was given two state scholarships to study instrument making abroad between 1872 and 1875. One of the companies he worked at was Siemens & Halske. Upon his return to Sweden in 1876, he founded a small mechanical workshop together with his friend Carl Johan Andersson who had also worked at ''Öllers & Co.''. This workshop was actually a form ...

Mobile Network Provider
A mobile network operator (MNO), also known as a wireless service provider, wireless carrier, cellular company, or mobile network carrier, is a provider of wireless communications services that owns or controls all the elements necessary to sell and deliver services to an end user, including radio spectrum allocation, wireless network infrastructure, back haul infrastructure, billing, customer care, provisioning computer systems, and marketing and repair organizations. Operator In addition to obtaining revenue by offering retail services under its own brand, an MNO may also sell access to network services at wholesale rates to mobile virtual network operators (MVNO). A key defining characteristic of a mobile network operator is that an MNO must own or control access to a radio spectrum license from a regulatory or government entity. A second key defining characteristic of an MNO is that it must own or control the elements of the network infrastructure necessary to provide se ...

Ernst Alexanderson
Ernst Frederick Werner Alexanderson (January 25, 1878 – May 14, 1975) was a Swedish-American electrical engineer, who was a pioneer in radio and television development. He invented the Alexanderson alternator, an early radio transmitter used between 1906 and the 1930s for longwave long distance radio transmission. Alexanderson also created the amplidyne, a direct current amplifier used during the Second World War for controlling anti-aircraft guns. Background Alexanderson was born in Uppsala, Sweden. He studied at the University of Lund (1896–97) and was educated at the Royal Institute of Technology in Stockholm and the Technische Hochschule in Berlin, Germany. He emigrated to the United States in 1902 and spent much of his life working for the General Electric and Radio Corporation of America.

John Robinson Pierce
John Robinson Pierce (March 27, 1910 – April 2, 2002), was an American engineer and author. He did extensive work concerning radio communication, microwave technology, computer music, psychoacoustics, and science fiction. Additionally to his professional career he wrote science fiction for many years using the names John Pierce, John R. Pierce, and J. J. Coupling. Born in Des Moines, Iowa, he earned his PhD from Caltech, and died in Sunnyvale, California, from complications of Parkinson's Disease. At Bell Labs Pierce wrote about electronics and information theory, and developed jointly the concept of pulse-code modulation (PCM) with his Bell Laboratories colleagues Bernard M. Oliver and Claude Shannon. He supervised the Bell Labs team which built the first transistor, and at the request of one of them, Walter Brattain, invented the term ''transistor''; he recalled: Pierce's early work at Bell Labs concerned vacuum tubes of all sorts. During World War II he discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
