Vienna University Of Technology
TU Wien (TUW; german: Technische Universität Wien; still known in English as the Vienna University of Technology from 1975–2014) is one of the major universities in Vienna, Austria. The university finds high international and domestic recognition in teaching as well as in research, and it is a highly esteemed partner of innovation-oriented enterprises. It currently has about 28,100 students (29% women), eight faculties and about 5,000 staff members (3,800 academics). The university's teaching and research is focused on engineering, computer science, and natural sciences. History The institution was founded in 1815 by Emperor Francis I of Austria as the '' k.k. Polytechnische Institut'' (Imperial-Royal Polytechnic Institute). The first rector was Johann Joseph von Prechtl. It was renamed the ''Technische Hochschule'' (College of Technology) in 1872. When it began granting doctoral and higher degrees in 1975, it was renamed the ''Technische Universität Wien'' (Vienna Univers ...

Christian Doppler
Christian Andreas Doppler ( (); 29 November 1803 – 17 March 1853) was an Austrian mathematician and physicist. He is celebrated for his principle – known as the Doppler effect – that the observed frequency of a wave depends on the relative speed of the source and the observer. Biography Doppler was born in Salzburg (today Austria) in 1803. After completing high school, Doppler studied philosophy in Salzburg and mathematics and physics at the Imperial–Royal Polytechnic Institute (now TU Wien), where he became an assistant in 1829. In 1835 he began work at the Prague Polytechnic (now Czech Technical University in Prague), where he received an appointment in 1841. One year later, at the age of 38, Doppler gave a lecture to the Royal Bohemian Society of Sciences and subsequently published his most notable work, '' Über das farbige Licht der Doppelsterne und einiger anderer Gestirne des Himmels'' ("On the coloured light of the binary stars and some other stars of the hea ...

Camillo Sitte
Camillo Sitte (17 April 1843 – 16 November 1903) was an Austrian architect, painter and urban theorist whose work influenced urban planning and land use regulation. Today, Sitte is best remembered for his 1889 book, ''City Planning According to Artistic Principles'', in which he examined and documented the traditional, incremental approach to urbanism in Europe, with a close focus on public spaces in Italy and the Germanic countries. Life Camillo Sitte was born Vienna in 1843. As the son of architect Franz Sitte, he was able to work on his father's construction sites during his youth. He was an architect and cultural theoretician whose writings, according to Eliel Saarinen, were familiar to German-speaking architects of the late 19th century. He was educated and influenced by Rudolf von Eitelberger and Heinrich von Ferstel, and on the recommendation of Eitelberger Sitte became the head of the new State Trade School in Salzburg in 1875, but Sitte returned to Vienna in 1883 to e ...

Benno Mengele
Benno Mengele (11 December 1898 in Zwettl, Lower Austria – 15 September 1971 in Vienna) was an Austrian electrical engineer. Mengele studied from 1918 to 1923 at the Vienna University of Technology and worked from 1922 at the Austrian Siemens-Schuckert. He developed protective earthing and fault current, and in 1929, he and Gustav Markt developed the overhead power line (bundle conductors) for high-voltage and ultrahigh-voltage power transmission. He also built the first hydrogen Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic ...-cooled three-phase motor in Austria.

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The surprise attack by the Imperial Japanese Navy on December 7, 1941, led the United States to declare war on the Empire of Japan, making the attack on Pearl Harbor the immediate cause of the United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning, “Waters of Pearl”) or ''Puuloa'' (meaning, “long hill”) by the Hawaiians. Puuloa wa ...

USS Arizona Memorial
The USS ''Arizona'' Memorial, at Pearl Harbor in Honolulu, Hawaii, marks the resting place of 1,102 of the 1,177 sailors and Marines killed on during the attack on Pearl Harbor on December 7, 1941, and commemorates the events of that day. The attack on Pearl Harbor led to the United States' involvement in World War II. The memorial, built in 1962, is visited by more than two million people annually. Accessible only by boat, it straddles the sunken hull of the battleship without touching it. Historical information about the attack, shuttle boats to and from the memorial, and general visitor services are available at the associated USS ''Arizona'' Memorial Visitor Center, which opened in 1980 and is operated by the National Park Service. The battleship's sunken remains were declared a National Historic Landmark on May 5, 1989. The USS ''Arizona'' Memorial is one of several sites in Hawaii that are part of the Pearl Harbor National Memorial. Memorial Conception and funding Du ...

Electronic Oscillator
An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave or a triangle wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clock generators to digital instruments (like calculators) and complex computers and peripherals etc. Common examples of signals generated by oscillators include signals broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers and video games. Oscillators are often characterized by the frequency of their output signal: *A low-frequency oscillator (LFO) is an electronic oscillator that generates a frequency below approximately 20 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
