Chartered Engineer
Regulation and licensure in engineering is established by various jurisdictions of the world to encourage life, public welfare, safety, well-being, then environment and other interests of the general public and to define the licensure process through which an engineer becomes licensed to practice engineering and to provide engineering professional services and engineered product to the public. As with many other professions and activities, engineering is a restricted activity. Relatedly, jurisdictions that license according to particular engineering discipline define the boundaries of each discipline carefully so that practitioners understand what they are competent to do. A licensed engineer takes legal responsibility for engineering work, product or projects (typically via a seal or stamp on the relevant design documentation) as far as the local engineering legislation is concerned. Regulations require that only a licensed engineer can sign, seal or stamp technical documentation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghana Secondary Technical School
The Ghana Secondary Technical School is a science and technology-oriented high school located in Takoradi on the west coast of Ghana. It is the third oldest high school in Ghana - the oldest 'non-missionary' high school. The School was founded on 9 August 1909 in Accra as Accra Technical School and later changed to Government Technical School. It moved to its current site in Takoradi in 1939. In 1953, the name was changed to Government Secondary Technical School, and in 1970, it was given its current name. Former students of the school are known as Giants, and students in the school are called Tescans. History The school was started in 1909 as a pure Technical School and was then sited at the former premises of the Accountant General (the current site of Kinbu Secondary Technical School in Accra). It was founded in response to the growing demand for technical education in the British colonies at that time. In 1939, the school was moved to Takoradi. The first head was Mr. T. T. ...

Royal Military College Of Science
The Royal Military College of Science (RMCS) was a British postgraduate school, research institution and training provider with origins dating back to 1772. It became part of the Defence Academy of the United Kingdom in 2009, and ceased to exist as an independent unit in 2015. History Predecessors The college traced its history back to the Military Society of Woolwich, founded by two Royal Artillery, artillery officers in 1772 'for the theoretical, practical and experimental study of gunnery'. The Society did not outlast the Napoleonic Wars; but in 1839, inspired by its example, two junior officers (Lt (later Gen Sir) John Henry Lefroy, J. H. Lefroy and Lt (later Maj-Gen) F. M. Eardley-Wilmot baronets, Eardley-Wilmot) proposed the formation of an Institute to train artillery officers along similar lines. This led to the establishment the following year of the Royal Artillery Institution "for the study of science and modern languages". Initially the RA Institution was suppor ...

Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Cockpit
A glass cockpit is an aircraft cockpit that features electronic (digital) flight instrument displays, typically large LCD screens, rather than the traditional style of analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges (nicknamed "steam gauges") to display information, a glass cockpit uses several multi-function displays driven by flight management systems, that can be adjusted to display flight information as needed. This simplifies aircraft operation and navigation and allows pilots to focus only on the most pertinent information. They are also popular with airline companies as they usually eliminate the need for a flight engineer, saving costs. In recent years the technology has also become widely available in small aircraft. As aircraft displays have modernized, the sensors that feed them have modernized as well. Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems (AHRS) and ...

Autopilot
An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"''). The etymology of the nickname is unclear: some claim it is a reference to inventor George De Beeson, who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to King George VI. First autopilots In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerobot
An aerobot is an aerial robot, usually used in the context of an unmanned space probe or unmanned aerial vehicle. While work has been done since the 1960s on robot "rovers" to explore the Moon and other worlds in the Solar System, such machines have limitations. They tend to be expensive and have limited range, and due to the communications time lags over interplanetary distances, they have to be smart enough to navigate without disabling themselves. For planets with atmospheres of any substance, however, there is an alternative: an autonomous flying robot, or "aerobot".Anthony Colozza, Geoffrey Landis, and Valerie Lyons, ''Overview of Innovative Aircraft Power and Propulsion Systems and Their Applications for Planetary Exploration,'' NASA TM-2003-212459 (July 2003link to NASA TM Most aerobot concepts are based on aerostats, primarily balloons, but occasionally airships. Flying above obstructions in the winds, a balloon could explore large regions of a planet in detail for relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Space Exploration
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by robotic spacecraft, uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chief Engineer
A chief engineer, commonly referred to as "ChEng" or "Chief", is the most senior engine officer of an engine department on a ship, typically a merchant ship, and holds overall leadership and the responsibility of that department..Chief engineer's rank is equivalent to the rank of a ship's captain. As a person who holds one of the most senior roles on the ship, they must have excellent communication and leadership skills. They will be expected to regularly work alongside other crew members and external consultants, and most importantly, provide guidance to their team. To be a chief engineer, an engineer must attain a chief engineer's license appropriate to the tonnage, power rating, and type of ship that they are employed on. A chief engineer is ultimately responsible for all operations and maintenance that has to do with any and all engineering equipment throughout the entire ship, and supervises all other engineering officer and engine ratings within the department.
