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. In 1934-1935 he fulfilled his compulsory military service in the Royal Italian Army, with the rank of second lieutenant in the Engineering Corps, and in July 1935 he was transferred at his own request to the Royal Italian Navy, with the rank of lieutenant in the Naval Weapons Corps. He worked as a researcher in the Higher Institute of Radio Transmissions in Rome until 1936, when he was exonerated from active se ...

Campobasso
Campobasso (, ; nap, label= Campobassan, Cambuàsce ) 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 the 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 ...

Second Lieutenant
Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank. Australia The rank of second lieutenant existed in the military forces of the Australian colonies and Australian Army until 1986. In the colonial forces, which closely followed the practices of the British military, the rank of second lieutenant began to replace ranks such as ensign and cornet from 1871. New appointments to the rank of second lieutenant ceased in the regular army in 1986. Immediately prior to this change, the rank had been effectively reserved for new graduates from the Officer Cadet School, Portsea which closed in 1985. (Graduates of the Australian Defence Force Academy (ADFA) and the Royal Military College, Duntroon (RMC-D) are commissioned as lieutenants.). The rank of second lieutenant is only appointed to officers in special appointments such as training institutions, university regiments and while under probation during training. Tra ...

Battle Of Cape Matapan
The Battle of Cape Matapan ( el, Ναυμαχία του Ταινάρου) 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 Royal Navy 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 ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doppler Effect
The Doppler effect or Doppler shift (or simply Doppler, when in context) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian 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. The reason for the Doppler effect is that when the source of the waves is moving towards the observer, each successive wave crest is emitted from a position closer to the observer than the crest of the previous wave. Therefore, each wave takes slightly less time to reach the observer than the previous wave. Hence, the time between the arrivals of successive wave crests at the observer is reduced, causing an ...

University Of Palermo
The University of Palermo ( it, Università degli Studi di Palermo) is a university located in Palermo, Italy, and founded in 1806. It is 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. A little later in history, 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 King 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, the same King Ferdinand 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. After the unification of Italy in 1860, the Universit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captain
Captain is a title, an appellative for the commanding officer of a military unit; the supreme leader of a navy ship, merchant ship, aeroplane, spacecraft, or other vessel; or the commander of a port, fire or police department, election precinct, etc. In militaries, the captain is typically at the level of an officer commanding a company or battalion of infantry, a ship, or a battery of artillery, or another distinct unit. The term also may be used as an informal or honorary title for persons in similar commanding roles. Etymology The term "captain" derives from (, , or 'the topmost'), which was used as title for a senior Byzantine military rank and office. The word was Latinized as capetanus/catepan, and its meaning seems to have merged with that of the late Latin "capitaneus" (which derives from the classical Latin word "caput", meaning head). This hybridized term gave rise to the English language term captain and its equivalents in other languages (, , , , , , , , , kapitány, K ...

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. Before it was incorporated in the Academy in 1913, it was first transformed into a prison and then a military barracks. The new hospital was considered one of the best in Europe.G.

Regia Marina
The ''Regia Marina'' (; ) was the navy of the Kingdom of Italy (''Regno d'Italia'') from 1861 to 1946. In 1946, with the birth of the Italian Republic (''Repubblica Italiana''), the ''Regia Marina'' changed its name to ''Marina Militare'' ("Military Navy"). Origins The ''Regia Marina'' 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 ''Regia Marina'' 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 ''Regia Marina'' was a heterogeneous mix of equipment, standards and p ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves 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 information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

Magnetic Waves
In physics, electromagnetism is an interaction that occurs between particles with electric charge. It is the second-strongest of the four fundamental interactions, after the strong force, and it is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electricity and magnetism, two distinct but closely intertwined phenomena. In essence, electric forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between ''moving'' charged particles. These two effects combine to create electromagnetic fields in the vicinity of charge particles, which can exert influence on other particles via the Lorentz force. At high energy, the weak force and electromagnetic force are unified as a single electroweak force. The electromagnetic force is responsible for many of t ...
