Ugo Tiberio
Ugo Tiberio (Campobasso, 19 August 1904 – Livorno, 17 May 1980) was an Italian engineer, naval officer and university teacher, best known for his role in the development of the Gufo radar. He was the nephew of naval officer and scientist Vincenzo Tiberio. Biography Born in Campobasso in 1904 from Alberto Tiberio and Maria Rachele De Feo, he was directed to a career in the Navy by his maternal uncle Vincenzo de Feo. After graduating in engineering at the University of Naples in 1927, he specialized in electrotechnics at the Higher School of Engineering in Rome in 1932.

Campobasso
Campobasso (, ; ) is a city and ''comune'' in southern Italy, the capital of the region of Molise and of the province of Campobasso. It is located in the high basin of the Biferno river, surrounded by Sannio and Matese mountains. Campobasso is renowned for the craftsmanship of blades (including scissors and knives), a fact well documented since the 14th century. It is also famous for the production of pears and scamorza (cheese). The city is home of the University of Molise and of the Archdiocese of Campobasso-Boiano. History The origins of Campobasso are disputed. According to the most widely held theory, the city was founded by the Lombards before the 8th century as a fortified camp on the slope of the hill where the castle stands. The original name was ''Campus vassorum'', suggesting that the city was the seat of the vassals of the duke of Spoleto. After the Norman conquest of Southern Italy, Campobasso lost its importance as a defensive stronghold, but became a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Cape Matapan
The Battle of Cape Matapan () was a naval battle during the Second World War between the Allies, represented by the navies of the United Kingdom and Australia, and the Royal Italian Navy, from 27 to 29 March 1941. Cape Matapan is on the south-western coast of the Peloponnesian peninsula of Greece. After the interception and decryption of Italian signals by the Government Code and Cypher School (GC&CS) at Bletchley Park (the decrypted intelligence codenamed Ultra), ships of the Royal Navy and Royal Australian Navy, under the command of Admiral Sir Andrew Cunningham, intercepted and sank or severely damaged several ships of the Italian '' Regia Marina'' under Squadron-Vice-Admiral Angelo Iachino. The opening actions of the battle are also known in Italy as the Battle of Gaudo. Background In late March 1941, as British ships of the Mediterranean Fleet covered troop movements to Greece, Mavis Batey, a cryptanalyst at Bletchley Park, made a breakthrough, reading the Ital ...

Doppler Effect
The Doppler effect (also Doppler shift) is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. The ''Doppler effect'' is named after the physicist Christian Doppler, who described the phenomenon in 1842. A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer. Compared to the emitted frequency, the received frequency is higher during the approach, identical at the instant of passing by, and lower during the recession. When the source of the sound wave is moving towards the observer, each successive cycle of the wave is emitted from a position closer to the observer than the previous cycle. Hence, from the observer's perspective, the time between cycles is reduced, meaning the frequency is increased. Conversely, if the source of the sound wave is moving away from the observer, each cycle of the wave is emitted from a position farther from ...

University Of Palermo
The University of Palermo () is a public university, public research university in Palermo, Italy. It was founded in 1806, and is currently organized in 12 Faculties. History The University of Palermo was officially founded in 1806, although its earliest roots date back to 1498 when medicine and law were taught there. Starting from the second half of the 16th century, from their seat at the Collegio Massimo al Cassero, the Jesuit Fathers granted degrees in Theology and Philosophy - subjects in which they had been masters for over 200 years. In 1767 they were expelled from the kingdom by Ferdinand I of the Two Sicilies, Ferdinand I, until 37 years later, when they returned to take their seat - which in the meantime had been turned into the Regia Accademia. At this time, Ferdinand I decided to grant a good seat to the Accademia, moving its location to the Convent of the Teatini Fathers next to the Church of St. Giuseppe. In 1806, the university was officially founded. After the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captain

Italian Naval Academy
The Italian Naval Academy (Italian: ''Accademia Navale'') is a coeducational military university in Livorno, which is responsible for the technical training of military officers of the Italian Navy. History The Hospitals The Hospital of St. James The Naval Academy stands on the former site of the Hospital of St. James, built in the 1640s for the quarantine of ships' crews from the Levant, which were previously diverted to the islands of Giglio and Elba. The Hospital of St. Leopold The Hospital of St. Leopold was designed by Ignatius Fazzi and built a little further south in 1773, by order of Leopold II. It was equipped with several towers, one of which served to guard the coast, two chapels and two cemeteries. It remained an active hospital until 1846.

Spanish Civil War
The Spanish Civil War () was a military conflict fought from 1936 to 1939 between the Republican faction (Spanish Civil War), Republicans and the Nationalist faction (Spanish Civil War), Nationalists. Republicans were loyal to the Left-wing politics, left-leaning Popular Front (Spain), Popular Front government of the Second Spanish Republic. The opposing Nationalists were an alliance of Falangism, Falangists, monarchists, conservatives, and Traditionalism (Spain), traditionalists led by a National Defense Junta, military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international Interwar period#Great Depression, political climate at the time, the war was variously viewed as class struggle, a War of religion, religious struggle, or a struggle between dictatorship and Republicanism, republican democracy, between revolution and counterrevolution, or between fascism and communism. The Nationalists won the war, which ended in early 1939, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regia Marina
The , ) (RM) or Royal Italian Navy was the navy of the Kingdom of Italy () from 1861 to 1946. In 1946, with the birth of the Italian Republic (''Repubblica Italiana''), the changed its name to '' Marina Militare'' ("Military Navy"). Origins The was established on 17 March 1861 following the proclamation of the formation of the Kingdom of Italy. Just as the Kingdom was a unification of various states in the Italian peninsula, so the was formed from the navies of those states, though the main constituents were the navies of the former kingdoms of Sardinia and Naples. The new Navy inherited a substantial number of ships, both sail- and steam-powered, and the long naval traditions of its constituents, especially those of Sardinia and Naples, but also suffered from some major handicaps. Firstly, it suffered from a lack of uniformity and cohesion; the was a heterogeneous mix of equipment, standards and practice, and even saw hostility between the officers from the various f ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Waves
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, nickel, and their alloys. All substances exhibit some type of magnetism. Magnetic materials are classified according to their bulk susceptibility. Ferromagnetism is responsible for most of the effects of magnetism encountered in everyday life, but there are actually several types of magnetism. Paramagnetic substances, such as aluminium and oxygen, are weakly attracted to an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
