Vityaz-D Autonomous Underwater Vehicle
The ''Vityaz-D'' is the first full-ocean depth, fully autonomous deep submergence vehicle. This Russian Autonomous Underwater Vehicle (AUV) was designed and developed by the Rubin Central Design Bureau for Marine Engineering in St. Petersburg, Russia under contract to the Advanced Research Foundation (Russian acronym: FPI, Fond Perspektivnyh Issledovaniy). The development of ''Vityaz-D'' began in September 2017. The keel-laying ceremony of the AUV was held at Rubin's assembly plant for experimental production in November 2018. It was tested in May 2020 with autonomous dives to 2400 meters in the Sea of Japan, to 5200 meters in the Philippine Sea, and culminating with a 10,028 meter dive into the Mariana Trench (note that the greatest depth of the Mariana Trench is 10,925 meters about 900 meters deeper than this ''Vityaz-D'' dive on 8 May 2020). Russia revealed the ''Vityaz-D'' program at the Army-2020 International Military and Technical Forum held in Kubinka, out ...

RV Vityaz (1939)
''Vityaz'' (russian: Витязь) is a research vessel that was built in 1939 by Deutsche Schiff- und Maschinenbau AG, Bremen, Germany as ''Mars'' for Neptun Line, Bremen. She served with the Kriegsmarine during World War II and was seized by the United Kingdom in 1945. She was renamed ''Empire Forth'' for the Ministry of War Transport (MoWT). She was allocated to the Soviet Union in 1946 under the terms of the Potsdam Agreement and renamed ''Equator'' (russian: Экватор) and later renamed ''Admiral Makarov'' (russian: Адмирал Мака́ров). She was renamed ''Vityaz'' in 1949 and was used as a research vessel. Retired in 1979, she was preserved as a museum ship in 1982. __FORCETOC__ Description When recorded in 1945, the ship was long, with a beam of . She had a depth of and a draught of .

Moore's Law
Moore's law is the observation that the number of transistors in a dense integrated circuit (IC) doubles about every two years. Moore's law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel (and former CEO of the latter), who in 1965 posited a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 41%. While Moore did not use empirical evidence in forecasting that the historical trend would continue, his prediction held since 1975 and has since become known as a "law". Moore's prediction has been used in the semiconductor industry to g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phase Transition
In chemistry, thermodynamics, and other related fields, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma. A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium, certain properties of the medium change as a result of the change of external conditions, such as temperature or pressure. This can be a discontinuous change; for example, a liquid may become gas upon heating to its boiling point, resulting in an abrupt change in volume. The identification of the external conditions at which a transformation occurs defines the phase transition point. Types of phase transition At the phase transition point for a substance, for instance the boiling point, the two phases involved - liquid and vapor, have identic ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

Ultrasonic
Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. History Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on t ...

VE Day
Victory in Europe Day is the day celebrating the formal acceptance by the Allies of World War II of Germany's unconditional surrender of its armed forces on Tuesday, 8 May 1945, marking the official end of World War II in Europe in the Eastern Front, with the last shots fired on the 11th. Russia and some former Soviet countries celebrate on 9 May. Several countries observe public holidays on the day each year, also called Victory Over Fascism Day, Liberation Day or Victory Day. In the UK it is often abbreviated to VE Day, or V-E Day in the US, a term which existed as early as September 1944, in anticipation of victory. The end of all combat actions was specified as 23:01 Central European Time, which was already 9 May in eastern Europe, and thus several former Soviet bloc countries including Russia and Belarus, as well as some former Yugoslav countries like Serbia, celebrate Victory Day on 9 May.
