ensemble comportant différents types d'appareillage associés à un ou plusieurs circuits électriques de départ alimentés par un ou plusieurs circuits électriques d'arrivée, ainsi que des bornes pour les conducteurs neutre et de protection.
[IEV number 826-16-08]Distribution switchboards, including the Main LV Switchboard (MLVS), are critical to the dependability of an electrical installation. They must comply with well-defined standards governing the design and construction of LV switchgear assemblies
A distribution switchboard is the point at which an incoming-power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard. A distribution switchboard is divided into a number of functional units, each comprising all the electrical and mechanical elements that contribute to the fulfilment of a given function. It represents a key link in the dependability chain.
Consequently, the type of distribution switchboard must be perfectly adapted to its application. Its design and construction must comply with applicable standards and working practises.
[Schneider Electric]Распределительные щиты, включая главный распределительный щит низкого напряжения (ГРЩ), играют решающую роль в обеспечении надежности электроустановки. Они должны отвечать требованиям соответствующих стандартов, определяющих конструкцию и порядок изготовления НКУ распределения электроэнергии.
В распределительном щите выполняется прием электроэнергии и ее распределение по отдельным цепям, каждая из которых контролируется и защищается плавкими предохранителями или автоматическими выключателями.
Распределительный щит состоит из функциональных блоков, включающих в себя все электрические и механические элементы, необходимые для выполнения требуемой функции. Распределительный щит представляет собой ключевое звено в цепи обеспечения надежности.
Тип распределительного щита должен соответствовать области применения. Конструкция и изготовление распределительного щита должны удовлетворять требованиям применимых стандартов и учитывать накопленную практику применения.
[Перевод Интент]

[Перевод Интент]The switchboard, central to the electrical installation.
Both the point of arrival of energy and a device for distribution to the site applications, the LV switchboard is the intelligence of the system, central to the electrical installation.
[Schneider Electric]Распределительный щит – «сердце» электроустановки.
Низковольтное комплектное устройство распределения является «сердцем» электроустановки, поскольку именно оно принимает электроэнергию из сети и распределяет её по территориально распределенным нагрузкам.

11 Ayrton, William Edward
[br]b. 14 September 1847 London, Englandd. 8 November 1908 London, England[br]English physicist, inventor and pioneer in technical education.[br]After graduating from University College, London, Ayrton became for a short time a pupil of Sir William Thomson in Glasgow. For five years he was employed in the Indian Telegraph Service, eventually as Superintendent, where he assisted in revolutionizing the system, devising methods of fault detection and elimination. In 1873 he was invited by the Japanese Government to assist as Professor of Physics and Telegraphy in founding the Imperial College of Engineering in Tokyo. There he created a teaching laboratory that served as a model for those he was later to organize in England and which were copied elsewhere. It was in Tokyo that his joint researches with Professor John Perry began, an association that continued after their return to England. In 1879 he became Professor of Technical Physics at the City and Guilds Institute in Finsbury, London, and later was appointed Professor of Physics at the Central Institution in South Kensington.The inventions of Avrton and Perrv included an electric tricycle in 1882, the first practicable portable ammeter and other electrical measuring instruments. By 1890, when the research partnership ended, they had published nearly seventy papers in their joint names, the emphasis being on a mathematical treatment of subjects including electric motor design, construction of electrical measuring instruments, thermodynamics and the economical use of electric conductors.

[këm'pju:të:] n 1. makinë llogaritëse; kompjuter, ordinator. 2. llogaritës, njehsues (person)- Kompjuteri është pajisje elektronike shumë e ndërlikuar që shërben për regjistrimin, transmetimin dhe përpunimin e informatave që mund të manifestohen si llogaritje, udhëheqje të proceseve, përpunim i tekstit, të dhënave të ndryshme si dhe për përdorime më të përgjithëshme. Kompjuteri, marrë në kuptimin e gjerë, përbëhet prej dy komponentëve të quajtura: harduer ( hardware - pjesë fizike e tij) dhe softuer ( software - programet dhe udhëzimet për punë). Me fjalë tjera, softueri është pjesa programore e hardueri pjesa mekanika e kompjuterit.● Hardueri përmban komponentet fizike të kompjuterit siç janë: tastiera ( Keyboard), monitori, shtypësi ( Printer), miu ( Mouse), disku i ngurtë ( Hard Disk), njësia e diskut, disketa ( Floppy Disk), njësia e disketës, CD-ROM-i ( CD ROM), njësia e CD-ROM-it, vizatuesi, modemi, lexuesi ( Scanner), kamera digjitale etj.● Softueri përmbanë programet dhe të dhënat të cilat e udhëzojnë kompjuterin në punën e tij, literatura, dokumentacioni dhe udhëzimet në lidhje me kompjuterin. Hardueri mund të krahasohet me gramafonin e disqet, ndërsa softueri me muzikën e inçizuar në disqe.)Zhvillimi historik i kompjuterit- Njeriu gjithmon ka tentuar të zgjidhë edhe problemet monotone, të vështira dhe të papërshtatshme. Gjatë zgjidhjeve të këtyre problemeve ka hasur në punë të vështira fizike, prandaj, çdo here ka tentuar që të liroj veten nga këta punë duke menduar makina të lloj-llojshme. Një makinë e këtyllë për lehtësimin e llogaritjeve aritmetike është makina e quajtur Abacus për të cilën dihet se është në përdorim prej para 5000 vjetëve. Kjo makinë i ngjanë numratores së sotme të cilën e përdorin nxënësit në klasë të pare dhe njihet si zanafilla e kompjuterëve të sotëm. Prej kohës së zbulimit të Abacusit e deri në shekullin 17 historia e zhvillimit të kompjuterëve nuk posedon të dhëna për ndonjë lëvizje në rrugën e zhvillimit të kompjuterëve.- Gjatë shekullit 17, respektivisht në vitin 1614 matematikani skocez J. Napier zbulon logaritmet dhe në vtin 1622 W. Oughtred ndërton kompjuterin (makinën) logaritmik cirkular për llogaritjen e logaritmeve.- Në vitin 1649 Blaise Pascal ndërton makinën mekanike për kryerjen e operacioneve aritmetike. Makina e Pascalit është e ndërtuar prej disa dhëmbëzorëve të cilët në lëvizje vendohen mekanikisht (me dorë). Ideja e konstruktimit të një makine-kalkulatori (kalkulator quhet makina e cila kryen operacionet aritmetike) ka qenë lehtësimi i punës së të atit të tij i cili ka qenë puntor i tatimeve (mbledhës i tatimeve) dhe ka patur nevojë për shumë llogaritje.- Në vitin 1672 G.W. Laibniz në Pariz projekton kalkulatorin mekanik më të përsosur nga dy të parët i cili me sukse do t'i kryej katër operacionet elementare aritmetike. Kufizimi në realizimin konkret të këtij kalkulatori ka qenë teknologjia e dobët e asaj kohe prandaj ky projekt ka ngelur i pa realizuar. Është interesant të përmendet se Laibnitz ka qenë pioneri i parë në hulumtimin e sistemit binar i cili përdoret në ndërtimin e kompjuterëve të sotëm. Gjatë 150viteve në vazhdim të gjithë tentimet për zhvillimin e kalkulatorëve kanë qenë të inspiruar nga kalkulatori i Laibnitzit.- Në vitin 1822 Anglezi Charles Babbage paraqet projekt të një kalkulatori krejtësisht të ndryshëm i dedikuar për llogaritjen e tabelave për funksione të caktuara. Projekti i këtillë do të finansoheshe nga qeveria Angleze e asaj kohe dhe do të përdoreshe për llogaritjen e tabelave për navigacionin detar. Për shkak të kompleksitetit dhe kushteve financiare e teknologjike ky projekt nuk u krye, në vitin 1842 definitivisht projekti u ndërpre. Makinën e këtillë Babbage e quajti makina diferenciale. Projektin e makinës diferenciale me sukse e realizuan Suedezët në vitin 1854 nën udhëheqen e P. G. Scheutza (duke i zbatuar sqarimet dhe vërejtjet e dhëna nga Babbage në 7000 faqe të shkruara) dhe makina e fituar nën pogon mekanik me sukse i llogariti tabelat (për 80 orë ka logarit 10000 logaritme).- Në vitin 1835 Babbage erdhi në idenë e konstruktimit të një makine programabile me funksionet që i kanë kompjuterët e tanishëm (me njësinë aritmetike-logjike, memorjen, etj.). Makinën e këtillë e quajti makina analitike. Për shkak të krizave finaciare dhe të vështirësive teknologjike kjo makinë ngeli vetëm në fazën e projektimit në letër por dha një inpuls të fuqishëm në zhvillimin e kompjuterëve të mëtutjeshëm.- Koha moderne fillon me përdorimin e energjisë elektrike në makinat për llogaritje. Në vitin 1884 emigranti gjerman në Amerikë Herman Holerith patenton makinën e pare elektrike e cila do të mund të rendit (sortoj) kartelat e shpuara me të dhënat për banorët e Amerikës. Makina e Holerithit në lëvizje vendoheshte me ndihmën e baterive. Qëllimi i kësaj makine ishte renditja e kartelave me të dhënat e banorëve të Amerikës të regjistruar në vitin 1890. Holerithi ishte inzhenier dhe punonte në institutin e statistikës, problem në atë kohë ishte përpunimi statistikor i të dhënave. Kështu regjistrimi statistikor në teren zgjatë disa muaj ndërsa përpunimi zgjate disa vjetë por bile edhe dhjetra vjetë dhe kur të dhënat përpunoheshin rezultatet e fituara ishin të vjetëruara (sepse regjistrimi statistikor zakonisht bëhet çdo 10 vjetë). Qeveria e asaj kohe shpall konkurs për përpunimin automatik të të dhënave me qëllim të përshpejtimit të përpunimit. Holerithi pasi punonte në institutin ku bëheshte përpunimi i të dhënave të këtylla, e njihte problemin dhe për këtë qëllim patentoi makinën e tij. Kështu me ndihmën e 56 makinave të Holerithit u aritë që të dhënat statistikore për popullsinë e Amerikës të përpunohen vetëm për gjashtë javë (në atë regjistrim Amerika doli me 62 622 250 banorë).- Pas këtij suksesi Holerithi themeloi kompaninë për prodhimin dhe huazimin e këtyre makinave (makina quheshe Tabulating Machine) me emrin Tabulating Machine Company e cila në vitin 1924 u bashkua me disa kompani të tjera dhe ndëroi emrin në IBM (International Business Machines), e njohur edhe sot.- Në vitin 1936 gjermani K. Zuse në Berlin arrinë të konstruktoj kalkulatorin programabil i cili do të mund të zgjidhë barazimet lineare. Zuse ariti të konstruktoj makinën e pare e cila shfrytëzonte sistemin binar, këtë makinë e konstriktoi në katër modele të njëpasnjëshëm Z1, Z2, Z3 dhe Z4, por modeli Z4 ngeli vetëm si ide interesante.- Me fillimin e luftës së dytë botërore interesimi për makina llogaritëse (kompjuterë) u zvoglua dhe gjithnjë mendohej në përmirësimin e armatimit. Mirëpo për prodhimin e armëve të reja artilerike nevoitej një hulumtin më i thellë dhe llogaritje të vështira, për hulumtime dhe llogaritje të thella nevoiteshe kohë e cila mungonte. Në vitin 1942 Fakulteti Moore School of Electrical Engineering nga Universiteti i Pensilvanisë bashkë me institutin Ballistic Research Laboratory nga armata Amerikane filloi hulumtimet për një makinë-kompjuter i cili do t'u lehtësonte punën puntorëve në industrinë ushtarake për prodhimin e armatimit artilerik respektivisht do të llogaritë tabelat balistike. Projekti deri në 1943 ishte në fshehtësi. Në vitin 1943 filloi ndërtimin nën udhëheqjen e udhëheqësve të projektit John W. Mauchly dhe J. Presper Eckert. Kompjuteri i menduar u quajt ENIAC (Electronic Numerical Integrator and Computer) dhe në përdorim u lëshua më 15 Shkurt 1946. Kompjuteri ENIAC meret si kompjuteri i parë i formës dhe me funksionet e kompjuterëve të sotëm. Me konstruktimin e ENIAC-ut fillon edhe gjenerata e parë e zhvillimit të kompjuterëve. Vlenë të përmendet se idenë për ndërtimin e kompjuterit të këtillë (në vitin 1930) e dha matematicienti John V. Atanasoff i cili në atë kohë punonte me kompjuterët analog për zgjidhjen e barazimeve lineare në lëminë e kërkimeve operacionale si dhe matematikani i shekullit 20 John von Neuman i cili ariti që teoretikisht ta përpunojë idenë dhe të bëjë sistematizimin e idesë.- Kompjuteri ENIAC përmbante afër 18000 llëmba elektronike, peshonte afër 30 tonë, zënte sipërfaqe prej 150 m2.- Kompjuterët e prodhuar prej vitit 1946 deri 1953 (kompjuterët EDVAC, ILLIAC, MANIAC etj.), njihen si gjenerata e parë dhe karakterizohen me llëmbat elektronike.- Me zbulimin e tranzistorit fillon gjenerata e dytë, kjo gjenerat zgjat prej vitit 1953 deri 1964. Tek kompjuterët e gjeneratës së dytë fillon zbatimi i gjuhëve të larta programore (Fortran-i paraqitet në vitin 1957, Algol në vitin 1961, etj.)- Gjenerata e tretë e kompjuterëve fillon në vitin 1964 dhe vazhdon deri në vitin 1971, kompjuterat e konstruktuar në këtë periudhë karakterisohen me qarqet e integruara-çipat.- Gjenerata e katër e kompjuterëve fillon në vitin 1971, kompjuterët e kësaj gjenerate karakterizohen me qarqet integrale të dendësisë së madhe LSI dhe VLSI (V-very). Gjenerata e katër e kompjuterëve ende është e hapur, PC kompjuterët e sotëm i takojnë gjeneratës së katër.- Për dallim nga katër gjeneratat e para kompjuterët e të cilave bëjnë përpunimin e të dhënave, kompjuterët e gjeneratës pestë e cila fillon në vitin 1981 bëjnë përpunimin e njohurive. Në këtë gjeneratë bien makinat e quajtura Robot.- Kompjuterët e gjeneratës së gjashtë (njëherit gjenerata e fundit e kompjuterëve) e cila fillon në vitin 1986 merren me përpunimin e inteligjencës. Kompjuterët e kësaj gjenerate quhen Neurocomputers (Kompjuterët neural, Kompjuterët biologjik) të cilët në punën e tyre tentojnë të imitojnë trurin dhe sistemin nervorë të njeriut. Këta kompjuterë në fillim të jetës mësojnë (me metoda speciale eksperimentale) dhe pastaj janë në gjendje të veprojnë pa prezencën dhe ndikimin e njeriut.PJESA PROGRAMORE E KOMPJUTERIT-SOFTUERISistemi operativ- Programet, asemblerët dhe kompajlerët ekzekutohen në kompjuter, në praninë e një mjedisi të caktuar programues. Këtë mjedis programues e përcakton sistemi operativ. Sistemi operativ është një grumbull i programeve i cili manipulon me resurset dhe shërbimet e sistemit kompjuterik (harduerit), siç janë memoria qëndrore, njësitë hyrëse-dalëse, etj. Pra sistemi operativ e komandon (manipulon) me hardverin e sistemit kompjuterik. Programi, në mënyrë implicite apo eksplicite, vetëm përmes direktivave të sistemit operativ mund t'i shfrytëzojë resurset dhe shërbimet e sistemit kompjuterik. Pra programi e urdhëron apo kërkon nga sistemi operativ shfrytëzimin e resurseve kompjuterike.- Nga kjo që u tha më sipër shihet se programet të cilat i shkruajmë (programeve aplikative) në gjuhët larta programuese, nuk e komandojnë harduerin, por i dërgojnë komanda sistemit operativ, i cili më pastaj manipulon me harduer për të arritur te rezultatet e dëshiruara. Kjo do të thotë se sistemi operativ është një lloj ndërmjetësuesi (interfejs) në mes të programeve aplikative dhe harduerit kompjuterik.- Roli kryesor i sistemit operativ është të shërbej si ndërmjetësues në mes të shfrytëzuesit dhe hardverit kompjuterik, dhe në mes të programeve aplikative dhe hardverit kompjuterik.- Ekzistojnë sisteme të ndryshme operative, mirëpo më të njohurat në PC janë MS-DOS dhe MS WINDOWS 95.- MS-DOS ( MicroSoft Disk Operating System), që do të thotë sistemi operativ i diskut i majkrosoftit. Nga këndi i vështrimit të programerit MS-DOS është sistem operativ hierarkial, që përmbanë tri nivele (shtresa), të cilat e ndajnë shfrytëzuesin dhe programet aplikative prej hardverit kompjuterik. Këto shtresa janë BIOS ( Basic Input-Output System që do të thotë sistemi themelor për hyrje-dalje), kerneli i DOS-it, dhe interpretuesi i komandave. Shtresa më e ulët është BIOS-i. BIOS-i kryesisht manipulon me këto njësi hardverike:● Konzolla (tastatiera dhe ekrani);● Printed i përgjithshëm;● Portet serike;● Orën e taktit të kompjuterit;● Diskun startues.- Kerneli i DOS-it, përveq tjerash, ofron shërbimet për:● Manipulimin e folderëve dhe fajllave;● Manipulimin e memories qëndrore;● Kohën dhe datën;● Menagjmentin e programeve aplikative.- Interpretuesi i komandave ka për detyrë që të ekzekutojë komandat të cilat ia jep shfrytëzuesi, duke kyçur edhe leximin dhe ekzekutimin e programeve aplikative.- Edhe pse Windows është paraqitur në mes të viteve 1980, nuk pati ndonjë sukses të madh në treg. Mirëpo me lansimin e verzionit Windows 3.0 më 1990, e sidomos me Windows 3.1 një vit më vonë e gjithë kjo ndryshoi, dhe tani Windows është produkt softverik i dyti më i shituri i të gjitha kohrave, pas MS DOS-it (e sidomos me lajmërimin e Windows 95/98).Windows punon se bashku me DOS-in por sillet si sistem operativ në vehte. Duke i shtuar nivel softverik mbi DOS, Windows-i i shton zgjerime grafike DOS-it.- Popullariteti i Windows-it i ka shtyer shumë programerë dhe shtëpi softverike botuese që të zhvillojnë aplikacione të cilat janë vetëm për Windows. Të gjitha këto aplikacione kanë një pamje të përgjithshme të ngjashme. Nëse dini të drejtoni një strukturë të menysë në një aplikacion të Windows-it atëherë dini të bëni të njejtën gjë edhe në aplikacionet tjera.- Përparësitë kryesore të Windows-it janë:● Platformë multitasking, në të cilën shumë aplikacione mund të ekzekutohen në të njejtën kohë.● Pamje gjenerale e ngjashme e të gjitha aplikacioneve të shkruara për Windows.● Mjedis grafik, i cili manipulohet me ndihmën e miut (apo tastierës).● Mundësia e shkëmbimit të informatave - duke përfshirë fotografi, dokumente, etj. ndërmjet aplikacioneve të ndryshme.● Një numër të veglave ndihmëse, duke përfshirë editor të tekstit, program per vizatim, kalkulator, program komunikues për modem, etj. computer dating [këm'pju:të:deiting] n. takim (dy personash) me ndihmën e sistemit informatik telefonik computerese [këmpju:të'ri:z] n. gj.fol. zhargon i / gjuhë e informatikës● computer game [këm'pju:të:geim] n. lojë elektronike, lojë me kompjuter● computer aided design, computer assisted design [këm'pju:të: eidid di'zain/ ë'sistid] n. vizatim teknik me kompjuter● computerist [këm'pju:tërist] n. amer. informatikan● computerization [këmpju:tërai'zeishën] n 1. trajtim elektronik, kompjuterizim; automatizim. 2. hedhje (të dhënash etj) në kompjuter● computerize [këm'pju:tëraiz] vt 1. informatizoj, kompjuterizoj; përpunoj në kompjuter. 2. hedh në kompjuter● computer language [këm'pju:'længwixh] n. gjuhë programimi● computer literate [këm'pju:'litërit] adj. që ka njohuri në informatikë, që njeh kompjuterin● computer operator [këm'pju:'opëreitë:(r)] n. kompjuterist, person që punon në/me kompjuter● computer programmer [këm'pju:'prëugræmë:(r)] n. kmp. programist● computer science [këm'pju:'saiëns]n. informatikë● computer studies [këm'pju:'stadis] n. informatikë* * *kompjuter -
13 Hopkinson, John
[br]b. 27 July 1849 Manchester, Englandd. 27 August 1898 Petite Dent de Veisivi, Switzerland[br]English mathematician and electrical engineer who laid the foundations of electrical machine design.[br]After attending Owens College, Manchester, Hopkinson was admitted to Trinity College, Cambridge, in 1867 to read for the Mathematical Tripos. An appointment in 1872 with the lighthouse department of the Chance Optical Works in Birmingham directed his attention to electrical engineering. His most noteworthy contribution to lighthouse engineering was an optical system to produce flashing lights that distinguished between individual beacons. His extensive researches on the dielectric properties of glass were recognized when he was elected to a Fellowship of the Royal Society at the age of 29. Moving to London in 1877 he became established as a consulting engineer at a time when electricity supply was about to begin on a commercial scale. During the remainder of his life, Hopkinson's researches resulted in fundamental contributions to electrical engineering practice, dynamo design and alternating current machine theory. In making a critical study of the Edison dynamo he developed the principle of the magnetic circuit, a concept also arrived at by Gisbert Kapp around the same time. Hopkinson's improvement of the Edison dynamo by reducing the length of the field magnets almost doubled its output. In 1890, in addition to-his consulting practice, Hopkinson accepted a post as the first Professor of Electrical Engineering and Head of the Siemens laboratory recently established at King's College, London. Although he was not involved in lecturing, the position gave him the necessary facilities and staff and student assistance to continue his researches. Hopkinson was consulted on many proposals for electric traction and electricity supply, including schemes in London, Manchester, Liverpool and Leeds. He also advised Mather and Platt when they were acting as contractors for the locomotives and generating plant for the City and South London tube railway. As early as 1882 he considered that an ideal method of charging for the supply of electricity should be based on a two-part tariff, with a charge related to maximum demand together with a charge for energy supplied. Hopkinson was one the foremost expert witnesses of his day in patent actions and was himself the patentee of over forty inventions, of which the three-wire system of distribution and the series-parallel connection of traction motors were his most successful. Jointly with his brother Edward, John Hopkinson communicated the outcome of his investigations to the Royal Society in a paper entitled "Dynamo Electric Machinery" in 1886. In this he also described the later widely used "back to back" test for determining the characteristics of two identical machines. His interest in electrical machines led him to more fundamental research on magnetic materials, including the phenomenon of recalescence and the disappearance of magnetism at a well-defined temperature. For his work on the magnetic properties of iron, in 1890 he was awarded the Royal Society Royal Medal. He was a member of the Alpine Club and a pioneer of rock climbing in Britain; he died, together with three of his children, in a climbing accident.[br]Principal Honours and DistinctionsFRS 1878.

14 Sperry, Elmer Ambrose
[br]b. 21 October 1860 Cincinnatus, Cortland County, New York, USAd. 16 June 1930 Brooklyn, New York, USA[br]American entrepreneur who invented the gyrocompass.[br]Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.[br]Principal Honours and DistinctionsJohn Fritz Medal 1927. President, American Society of Mechanical Engineers 1928.BibliographySperry filed over 400 patents, of which two can be singled out: 1908. US patent no. 434,048 (ship gyroscope); 1909. US patent no. 519,533 (ship gyrocompass set).Further ReadingT.P.Hughes, 1971, Elmer Sperry, Inventor and Engineer, Baltimore: Johns Hopkins University Press (a full and well-documented biography, with lists of his patents and published writings).LRD -

SUBJECT AREA: Electronics and information technology[br]b. 26 June 1913 Stourbridge, Worcestershire, England[br]English physicist who was jointly responsible for the construction of the EDS AC computer.[br]Educated at King Edward VI Grammar School, Stourbridge, where he began to make radio sets and read Wireless World, Wilkes went to St John's College, Cambridge, in 1931, graduating as a Wrangler in the Mathematical Tripos in 1934. He then carried out research at the Cavendish Laboratory, becoming a demonstrator in 1937. During the Second World War he worked on radar, differential analysers and operational research at the Bawdsey Research Station and other air-defence establishments. In 1945 he returned to Cambridge as a lecturer and as Acting Director of the Mathematical (later Computer) Laboratory, serving as Director from 1946 to 1970.During the late 1940s, following visits to the USA for computer courses and to see the ENIAC computer, with the collaboration of colleagues he constructed the Cambridge University digital computer EDSAC (for Electronic Delay Storage Automatic Computer), using ultrasonic delay lines for data storage. In the mid-1950s a second machine, EDSAC2, was constructed using a magnetic-core memory. In 1965 he became Professor of Computer Technology. After retirement he worked for the Digital Electronic Corporation (DEC) from 1981 to 1986, serving also as Adjunct Professor of Computer Science and Electrical Engineering at the Massachusetts Institute of Technology from 1981 to 1985. In 1990 he became a research strategy consultant to the Olivetti Research Directorate.[br]Principal Honours and DistinctionsFRS 1956. First President, British Computer Society 1957–60.

[br]b. 14 April 1898 Leominster, Massachusetts, USAd. 11 December 1983 Summitt, New Jersey, USA[br]American electrical engineer who discovered that the application of negative feedback to amplifiers improved their stability and reduced distortion.[br]Black graduated from Worcester Polytechnic Institute, Massachusetts, in 1921 and joined the Western Electric Company laboratories (later the Bell Telephone Laboratories) in New York City. There he worked on a variety of electronic-communication problems. His major contribution was the discovery in 1927 that the application of negative feedback to an amplifier, whereby a fraction of the output signal is fed back to the input in the opposite phase, not only increases the stability of the amplifier but also has the effect of reducing the magnitude of any distortion introduced by it. This discovery has found wide application in the design of audio hi-fi amplifiers and various control systems, and has also given valuable insight into the way in which many animal control functions operate.During the Second World War he developed a form of pulse code modulation (PCM) to provide a practicable, secure telephony system for the US Army Signal Corps. From 1963–6, after his retirement from the Bell Labs, he was Principal Research Scientist with General Precision Inc., Little Falls, New Jersey, following which he became an independent consultant in communications. At the time of his death he held over 300 patents.[br]Principal Honours and DistinctionsInstitute of Electronic and Radio Engineers Lamme Medal 1957.Bibliography1934, "Stabilised feedback amplifiers", Electrical Engineering 53:114 (describes the principles of negative feedback).21 December 1937, US patent no. 2,106,671 (for his negative feedback discovery.1947, with J.O.Edson, "Pulse code modulation", Transactions of the American Institute of Electrical Engineers 66:895.1946, "A multichannel microwave radio relay system", Transactions of the American Institute of Electrical Engineers 65:798.1953, Modulation Theory, New York: D.van Nostrand.1988, Laboratory Management: Principles \& Practice, New York: Van Nostrand Rheinhold.Further ReadingFor early biographical details see "Harold S.

18 prototype
1) прототип, макет(от греч. prototypon - прообраз) частичная, предварительная версия программы (приложения) или первичная версия системы, служащая для её оценивания и/или более глубокого понимания сущности проблемы, рисков, правильности требований и т. п. Прототип может быть аппаратным (hardware prototype, physical prototype) и программным (software prototype, virtual prototype). Прототип может содержать дополнительное оборудование и средства диагностики, которые не войдут в состав конечного продукта."Sun introduced its first real product, the Sun-2, in late 1982. The Sun-1 was essentially prototype" (Karen Southwick). — В конце 1982 г. фирма Sun представила свой первый реальный продукт - рабочую станцию Sun-2, так как Sun-1 по существу была только прототипом.
Almost all products get prototyped at least once during their design. — Почти все изделия (продукты) в процессе разработки по крайней мере единожды проходили этап макетирования см. тж. conceptual prototype, evolutionary prototype, hardware prototype, horizontal prototype, laboratory prototype, mock-up, paper prototype, pilot prototype, procedure prototype, production prototype, prototype declaration, prototype device, prototype language, prototype system, prototyping, prototyping board, research prototype, software development, throwaway prototype, vertical prototype, virtual prototype

разработка ПО, программированиеметодология и совокупность этапов создания программы, приложения, системы. Для встраиваемого ПО на первых этапах его разработки обычно используется компьютерное моделирование (simulation), поскольку (если) ещё не создана целевая аппаратура; следующие этапы - это лабораторные прототипы (laboratory prototype), пилотные прототипы (pilot prototype) и, наконец, реальная производственная система (production system)Англо-русский толковый словарь терминов и сокращений по ВТ, Интернету и программированию. > software development
