Republic Of Singapore Air Force Eurocopter AS332 Super Puma Taking Off From The RSS Resolution With The USS Russell On The Horizon - 20040607
A republic, based on the Latin phrase ''res publica'' ('public affair' or 'people's affair'), is a State (polity), state in which Power (social and political), political power rests with the public (people), typically through their Representative assembly, representatives—in contrast to a monarchy. Although a republic is most often a single sovereign state, subnational state entities that have governments that are republican in nature may be referred to as republics. Representation in a republic may or may not be freely elected by the general citizenry. In many historical republics, representation has been based on personal status and the role of elections has been limited. This remains true today; among the List of countries by system of government, 159 states that use ''republic'' in their official names , and other states formally constituted as republics, are states that narrowly constrain both the right of representation and the process of election. The term developed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chilean Navy
The Chilean Navy () is the naval warfare service branch of the Chilean Armed Forces. It is under the Ministry of National Defense (Chile), Ministry of National Defense. Its headquarters are at Edificio Armada de Chile, Valparaiso. History Origins and the Wars of Independence (1817–1830) The origins of the Chilean Navy date back to 1817, when General Bernardo O'Higgins prophetically declared after the Chilean victory at the Battle of Chacabuco that a hundred such victories would count for nothing if Chile did not gain control of the sea. This led to the development of the Chilean Navy, and the first legal resolutions outlining the organization of the institution were created. Chile's First National Fleet and the Academy for Young Midshipmen, which was the predecessor of the current Naval Academy, were founded, as well as the Chilean Marine Corps, Marine Corps and the Supply Commissary. The first commander of the Chilean Navy was Manuel Blanco Encalada. Famous British nav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic Of Singapore Navy
The Republic of Singapore Navy (RSN) is the Naval warfare, maritime Military branch, service branch of the Singapore Armed Forces (SAF) responsible for defending the country against any seaborne threats and as a guarantor of its sea lines of communications. The RSN traces its origins to the Royal Navy when Singapore was still a crown colony of the British Empire. The service was formally established in 1967, two years after its independence from Malaysia in 1965, and had undergone a substantial modernisation ever since – which has led them into becoming the most powerful navy in Southeast Asia. The RSN also regularly conducts operations with the navies of its neighbouring countries to combat Piracy in the Strait of Malacca, piracy and terrorist threats in the congested littoral waters of the Strait of Malacca and Singapore. It also jointly operates the Fokker 50 maritime patrol aircraft with its counterparts from the Republic of Singapore Air Force (RSAF) to provide air surv ...

Turkish Navy
The Turkish Naval Forces (), or Turkish Navy (), is the naval warfare service branch of the TAF. The modern naval traditions and customs of the Turkish Navy can be traced back to 10 July 1920, when it was established as the ''Directorate of Naval Affairs'' during the Turkish War of Independence led by Mustafa Kemal Atatürk. Since July 1949, the service has been officially known as the ''Turkish Naval Forces''. In 2008, the Turkish Navy had a reported active personnel strength of 48,600; this figure included an Amphibious Marines Brigade as well as several Special Forces and Commando detachments.

Electro-optic
Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials. It is closely related to photonics, the branch of optics that involves the application of the generation of photons. It is not only concerned with the " electro–optic effect", since it deals with the interaction between the electromagnetic (optical) and the electrical ( electronic) states of materials. Electro-optical devices The electro-optic effect is a change in the optical properties of an optically active material in response to changes in an electric field. This interaction usually results in a change in the birefringence Birefringence, also called double refraction, is the optical property of a material having a refractive index that depends on the polarizat ...

Real-time Computing
Real-time computing (RTC) is the computer science term for Computer hardware, hardware and software systems subject to a "real-time constraint", for example from Event (synchronization primitive), event to Event (computing), system response. Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".Mordechai Ben-Ari, Ben-Ari, Mordechai; "Principles of Concurrent and Distributed Programming", ch. 16, Prentice Hall, 1990, , p. 164 The term "real-time" is also used in Computer simulation, simulation to mean that the simulation's clock runs at the same speed as a real clock. Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds. A system not specified as operating in real time cannot usually ''guarantee'' a response within any timeframe, although ''typical'' or ''expected'' response times may be given. Real-time processing ''fails'' if not completed within a specified deadline rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hover (helicopter)
Helicopter flight controls are used to achieve and maintain controlled aerodynamic helicopter flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a desired way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades ''cyclically'' during rotation, creating differing amounts of lift at different points in the cycle. To increase or decrease overall lift requires that the controls alter the angle of attack for all blades ''collectively'' by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration. A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a ''mixing unit'', a mechanical or hydra ...

Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their Glider aircraft, glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modularity
Modularity is the degree to which a system's components may be separated and recombined, often with the benefit of flexibility and variety in use. The concept of modularity is used primarily to reduce complexity by breaking a system into varying degrees of interdependence and independence across and "hide the complexity of each part behind an abstraction and interface". However, the concept of modularity can be extended to multiple disciplines, each with their own nuances. Despite these nuances, consistent themes concerning modular systems can be identified. Composability is one of the tenets of functional programming. This makes functional programs modular. Contextual nuances The meaning of the word "modularity" can vary somewhat based on context. The following are contextual examples of modularity across several fields of science, technology, industry, and culture: Science *In biology, modularity recognizes that organisms or metabolic pathways are composed of modules. *I ...
