Defence Research And Development Canada
Defence Research and Development Canada (DRDC; french: Recherche et développement pour la défense Canada, ''RDDC'') is a special operating agency of the Department of National Defence (DND), whose purpose is to provide the Canadian Armed Forces (CAF), other government departments, and public safety and national security communities with knowledge and technology. DRDC has approximately 1,400 employees across eight research centres within Canada. History After the First World War, national research and development in Canada was organized under the National Research Council (NRC). The NRC was founded in 1925 based on a wartime British recommendation to establish military laboratories in Canada, but by that time the main priorities were developing domestic university and industrial research and civilian projects.Turner, p.15 Greater interest in military applied research arrived in 1935Turner, p.16 when Major-General Andrew McNaughton became President of the NRC.;Turner, p.17 in ...

Government Of Canada
The government of Canada (french: gouvernement du Canada) is the body responsible for the federal administration of Canada. A constitutional monarchy, the Crown is the corporation sole, assuming distinct roles: the executive, as the ''Crown-in-Council''; the legislature, as the ''Crown-in-Parliament''; and the courts, as the ''Crown-on-the-Bench''. Three institutions—the Privy Council ( conventionally, the Cabinet); the Parliament of Canada; and the judiciary, respectively—exercise the powers of the Crown. The term "Government of Canada" (french: Gouvernement du Canada, links=no) more commonly refers specifically to the executive— ministers of the Crown (the Cabinet) and the federal civil service (whom the Cabinet direct)—which corporately brands itself as the ''Government of Canada'', formally known as '' Majesty's Government'' (french: Gouvernement de Sa Majesté, links=no). There are over one hundred ministries, departments and crown corporations and over 300 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manikin
A mannequin (also called a dummy, lay figure, or dress form) is a doll, often articulated, used by artists, tailors, dressmakers, window dressers and others, especially to display or fit clothing and show off different fabrics and textiles. Previously, the English term referred to human models and muses (a meaning which it still retains in French and other European languages); the meaning as a dummy dating from the start of World War II. Life-sized mannequins with simulated airways are used in the teaching of first aid, CPR, and advanced airway management skills such as tracheal intubation. During the 1950s, mannequins were used in nuclear tests to help show the effects of nuclear weapons on humans. Also referred to as mannequins are the human figures used in computer simulation to model the behavior of the human body. ''Mannequin'' comes from the French word ', which had acquired the meaning "an artist's jointed model", which in turn came from the Flemish word ', meaning "l ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most ...

Virtual Reality
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

Dive Tables
The practice of decompression by divers comprises the planning and monitoring of the profile indicated by the algorithms or tables of the chosen decompression model, to allow asymptomatic and harmless release of excess inert gases dissolved in the tissues as a result of breathing at ambient pressures greater than surface atmospheric pressure, the equipment available and appropriate to the circumstances of the dive, and the procedures authorized for the equipment and profile to be used. There is a large range of options in all of these aspects. Decompression may be continuous or staged, where the ascent is interrupted by stops at regular depth intervals, but the entire ascent is part of the decompression, and ascent rate can be critical to harmless elimination of inert gas. What is commonly known as no-decompression diving, or more accurately no-stop decompression, relies on limiting ascent rate for avoidance of excessive bubble formation. Staged decompression may include deep s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DRDC Toronto
DRDC Toronto is a major military research station located at the former site of CFB Downsview in Toronto, Ontario, Canada. It is one of several centres making up Defence Research and Development Canada (DRDC). History The Centre's roots go back to 1939 when the Department of National Defence (DND) recognized the vital importance of human factors in the ability of Canada's armed forces to safeguard the nation in peacetime and at war. Recognizing the importance of aviation medicine to defence, an inter-departmental committee, the Associate Committee on Aviation Medical Research, was established in June, 1939, chaired by Sir Frederick Banting. Laboratory studies in pressure physiology began in the Banting and Best Institute, University of Toronto, where the first decompression chamber for human studies in Canada was set up. To expand the effort, in 1940, the No.1 Clinical Investigation Unit (No1 CIU) was formed at the former Eglinton Hunt Club at 1107 Avenue Road with the constructi ...

CFB Valcartier
Canadian Forces Base Valcartier (CFB Valcartier), now re-designated 2 Canadian Division Support Base Valcartier (2 CDSB Valcartier), is a Canadian Forces base located in the municipality of Saint-Gabriel-de-Valcartier, north northwest of Quebec City, Quebec, Canada. The 2nd Canadian Division is stationed at the base, comprising the 5 Canadian Mechanized Brigade Group and the 2nd Canadian Division Support Group. Origins CFB Valcartier was originally erected as a military training camp in August 1914 as part of the mobilization of the Canadian Expeditionary Force at the onset of World War I. Inaugurated by Jean Chrétien, then Prime Minister of Canada, in 1995, a high bronze figure of a World War I soldier (1995) by André Gauthier at the entrance to CFB Valcartier commemorates the training of Canadian Army volunteers for the European battlefields in World War I. The site was also used as an internment camp for "enemy aliens", mainly eastern Europeans. The name Valcartie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DRDC Valcartier
DRDC Valcartier is a major Canadian military research station at Canadian Forces Base Valcartier, Quebec, one of nine centres making up Defence Research and Development Canada (DRDC). Originally formed at the end of World War II in 1945 as the Canadian Armament Research and Development Establishment (CARDE), the intent was to keep the research teams built up during the war in Canada, as opposed to moving to the United States. Starting in 1951 CARDE implemented a major missile development program, eventually delivering two combat systems, the Velvet Glove air-to-air missile and the Heller anti-tank rocket. Neither was accepted for production, but the basic research was used with local defence contractors to build up familiarity with the new technologies. Starting in 1955 a serious effort to equip Canada with a useful anti-ballistic missile system was undertaken, along with research into the problems of detection and tracking, hypersonic flight, and fuels suitable for use in an ...
