Aksel Berg
Aksel Ivanovich Berg (russian: Аксель Иванович Берг; – 9 July 1979) was a Soviet scientist in radio-frequency engineering and Soviet Navy Admiral, Hero of Socialist Labour. He was a key figure in the introduction of cybernetics to the Soviet Union. Early life Berg's father was General Johan (Ivan) Berg, of Finland-Swedish origin, and his mother was Italian. Aksel was 11 when his father died, and Aksel was matriculated to Saint Petersburg navy school. Berg joined the Imperial Russian Navy in 1914 and served as junior navigating officer on the Russian battleship Tsesarevich and as liaison officer on the British submarine HMS E8, which was operating in the Baltic in alliance with Russia. Soviet times Before the German-Soviet war After the revolution Berg served in the Red Navy 1918–22. In 1918 he participated in the Ice Cruise of the Baltic Fleet.

Orenburg
Orenburg (russian: Оренбу́рг, ), formerly known as Chkalov (1938–1957), is the administrative center of Orenburg Oblast, Russia. It lies on the Ural River, southeast of Moscow. Orenburg is also very close to the Kazakhstan-Russia border, border with Kazakhstan. Population: Name Several historians have tried to explain the origins of the city's name. It was traditionally accepted that the word "orenburg" means a fortress on the Or River, River Or. In all probability, the word combination "orenburg" was proposed by , the founder of the city. In 1734, in accordance with his project, a package of governmental documents was worked out. This was the starting point for Orenburg as a fortress city near the meeting of the Or (river), Or and Ural rivers. On 7 June 1734, "A Privilege for Orenburg" (tsar's edict) was ordered by Anna of Russia, Empress Anna Ioannovna. While the construction site of the main fortress changed many times (down the River Ural), the name "Orenburg" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Submarine Flotilla In The Baltic
A British submarine flotilla operated in the Baltic Sea for three years during the First World War. The squadron of nine submarines was attached to the Russian Baltic Fleet. The main task of the flotilla was to prevent the import of iron ore from Sweden to Imperial Germany. The success of the flotilla also forced the German Navy in the Baltic to keep to their bases and denied the German High Seas Fleet a training ground. The flotilla was based in Reval (Tallinn), and for most of its career commanded by Captain Francis Cromie. The flotilla originally consisted of six E-class and five C-class submarines. The smaller C-class submarines reached the Baltic Sea from the White Sea via northern rivers; the long-range E-class submarines managed to enter the German backwaters by passing undetected through the narrow and shallow Danish Straits. Two submarines were lost to stranding and one went missing, now presumed sunk by a mine. In 1918, the German occupation of Tallinn and the Br ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

Cybernetic
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics. London: Chapman & Hall, p. 1. including in ecological, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, conversation, and the practice of cybernetics itself. Cybernetics' transdisciplinary and "antidisciplinary" character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

Microelectronic
Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller. These devices are typically made from semiconductor materials. Many components of normal electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive. Digital integrated circuits (ICs) consist of billions of transistors, resistors, diodes, and capacitors. Analog circuits commonly contain resistors and capacitors as well. Inductors are used in som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiolocation
Radiolocation, also known as radiolocating or radiopositioning, is the process of finding the location of something through the use of radio waves. It generally refers to passive uses, particularly radar—as well as detecting buried cables, water mains, and other public utilities. It is similar to radionavigation, but radiolocation usually refers to passively finding a distant object rather than actively one's own position. Both are types of radiodetermination. Radiolocation is also used in real-time locating systems (RTLS) for tracking valuable assets. Basic principles An object can be located by measuring the characteristics of received radio waves. The radio waves may be transmitted by the object to be located, or they may be backscattered waves (as in radar or passive RFID). A stud finder uses radiolocation when it uses radio waves rather than ultrasound. One technique measures a distance by using the difference in the power of the received signal strength (RSSI) as co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Barbarossa
Operation Barbarossa (german: link=no, Unternehmen Barbarossa; ) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. The operation, code-named after Frederick Barbarossa ("red beard"), a 12th-century Holy Roman emperor and German king, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories. Their ultimate goal was to create more (living space) for Germany, and the eventual extermination of the indigenous Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. In the two years leading up to the invasion, Nazi Germany and the Soviet Union signed political and economic pacts for st ...

Sevastopol
Sevastopol (; uk, Севасто́поль, Sevastópolʹ, ; gkm, Σεβαστούπολις, Sevastoúpolis, ; crh, Акъя́р, Aqyár, ), sometimes written Sebastopol, is the largest city in Crimea, and a major port on the Black Sea. Due to its strategic location and the navigability of the city's harbours, Sevastopol has been an important port and naval base throughout its history. Since the city's founding in 1783 it has been a major base for Russia's Black Sea Fleet, and it was previously a closed city during the Cold War. The total administrative area is and includes a significant amount of rural land. The urban population, largely concentrated around Sevastopol Bay, is 479,394, and the total population is 547,820. Sevastopol, along with the rest of Crimea, is internationally recognised as part of Ukraine, and under the Ukrainian legal framework, it is administratively one of two cities with special status (the other being Kyiv). However, it has been occupied b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Cruiser Molotov
''Molotov'' (russian: Молотов) was a Project 26bis of the Soviet Navy that served during World War II and into the Cold War. She supported Soviet troops during the Siege of Sevastopol, the Kerch-Feodosiya Operation and the amphibious landings at Novorossiysk at the end of January 1943. The ship was extensively modernized between 1952 and 1955. She was renamed ''Slava'' (russian: Слава, ''Glory'') in 1957 after Vyacheslav Molotov fell out of favour. ''Slava'' was reclassified as a training ship in 1961 before being sold for scrap in 1972. Description ''Molotov'' and her sister ''Maxim Gorky'' had heavier armor and were slightly improved from the first two ''Kirov''-class cruisers of Project 26, and were thus designated Project 26bis. She was long at the waterline, long overall, with a beam of and a draft between . She displaced at standard load and at full load.Yakubov and Worth, p. 84 Her steam turbines produced a total of during her sea trials, reac ...
