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 network provider, mobile communication network provider, holding 35 ... [...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 that use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after the commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is 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, Electromagnetism, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control ...

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''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (wikt:Appendix:Proto-Indo-European/ǵerh₂-">ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain." An old man has been worn away and is now grey with age. In some Slavic languages, the name ''Drago (given name), Drago'' (and variants: ''Dr ...

KTH - Royal Institute Of Technology
KTH Royal Institute of Technology (), abbreviated KTH, is a Public university, public research university in Stockholm, Sweden. KTH conducts research and education in Institute of technology, engineering and technology and is Sweden's largest technical university. Since 2018, KTH consists of five #Schools, schools with four #Campuses, 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 Techn ... [...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''). Early life 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. Career 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 ...

Mobile Network Provider
A mobile network operator (MNO), also known as a mobile network provider, mobile network carrier, mobile , wireless service provider, wireless carrier, wireless operator, wireless telco, or cellular company, is a telecommunications provider of services that sells, delivers and maintains mobile telephony services to an end user. Overview A key defining characteristic of a mobile network operator is that it must own or control access to a radio spectrum license from a regulatory or government entity, and also that it must own or control the elements of the cellular network infrastructure necessary to provide services to subscribers over the licensed radio spectrum. In addition the operator would also contain other elements like the back haul infrastructure and provisioning computer systems. A mobile network operator typically also has the necessary provisioning, billing, and customer care computer systems, and the marketing, customer care, and engineering organizations needed ...

Ernst Alexanderson
Ernst Frederick Werner Alexanderson (; January 25, 1878 – May 14, 1975) was a Swedish-American electrical engineer and inventor who was a pioneer in radio 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.
