Capacitor Voltage Transformer
Voltage transformers (VT), also called potential transformers (PT), are a parallel-connected type of instrument transformer. They are designed to present a negligible load to the supply being measured and have an accurate voltage ratio and phase relationship to enable accurate secondary connected metering. Ratio The PT is typically described by its voltage ratio from primary to secondary. A 600:120 PT will provide an output voltage of 120 volts when 600 volts are impressed across its primary winding. Standard secondary voltage ratings are 120 volts and 70 volts, compatible with standard measuring instruments. Burden and accuracy Burden and accuracy are usually stated as a combined parameter due to being dependent on each other. Metering style PTs are designed with smaller cores and VA capacities than power transformers. This causes metering PTs to saturate at lower secondary voltage outputs saving sensitive connected metering devices from damaging large v ...

Certified Veterinary Technician
Paraveterinary worker is the professional of veterinary science that performs procedures autonomously or semi autonomously, as part of a veterinary assistance system. The job role varies throughout the world, and common titles include veterinary nurse, veterinary technician and veterinary assistant, and variants with the prefix of 'animal health'. The scope of practice varies between countries, with some countries allowing suitably qualified paraveterinary workers a scope of autonomous practice, including minor surgery, whilst others restrict their workers as assistants to other professionals. Nomenclature Veterinary technician / nurse In North America, paraveterinary workers who have completed a course of study, passed an examination, and have a defined scope of practice are called veterinary technicians. Veterinary technicians hold a technician degree in Veterinary Technology. Most Canadian provinces have a formal registration process and, legally, veterinarians must hire reg ...

Hull Classification Symbol
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use. History United States Navy The U.S. Navy began to assign unique Naval Registry Identification Numbers to its ships in the 1890s. The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the battleship ''Indiana'' was USS ''Indiana'' (Battleship No. 1), the cruiser ''Olympia'' was USS ''Olympia'' (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coventry Airport
Coventry Airport is located south-southeast of Coventry city centre, in the village of Baginton, Warwickshire, England. The airport is operated and licensed by Coventry Airport Limited. Its CAA Ordinary Licence (Number P902) allows flights for the public transport of passengers or for flying instruction. Since October 2017, Coventry Airport has been undergoing transition to a general aviation aerodrome offering a flight information service. History First opened in 1936 as Baginton Aerodrome, Coventry Airport has been used for general aviation, flight training, and commercial freight and passenger flights, as well as being a World War II fighter airfield. In 1982, Pope John Paul II celebrated Mass with a crowd of around 350,000 on his only UK visit. In 1994–5, it became a focus for animal rights campaigners who protested at the export of live animals from the airport as freight. From 2004 to 2008, Thomsonfly operated scheduled jet passenger flights from temporary hub fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuously Variable Transmission
A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds. CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and earthmoving equipment. The most common type of CVT uses two pulleys connected by a belt or chain; however, several other designs have also been used at times. Types Pulley-based The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two-halves, so the effective diameter of the pulley is dependent on the distance between the two-halves of the pulley. The V- ...

Northgate Computers
__NOTOC__ Northgate Computer Systems, Inc., based in Eden Prairie, Minnesota, United States, was a mail-order personal computer company, founded in 1987 by Arthur "Art" Lazere. The 1990s were a golden era for mail-order PC business. Consumers were fed up with high prices for IBM, Compaq and other brand-name PCs sold through dealers so they opted to purchase their computers from a catalog. This was a revolutionary idea at the time, because people wouldn't be able to see or touch their computer before buying it. Aside from Dell and Gateway, popular brands of mail-order PCs were Northgate and Zeos. The company was known for its quality systems and keyboards; in particular, its line of OmniKey keyboards was highly praised. The keyboards were particularly valued for their tactile response and durability, and along with IBM's Model M PC keyboards, were considered some of the best in the industry. As such, the company's keyboards were often purchased by users of other manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centroidal Voronoi Tessellation
In geometry, a centroidal Voronoi tessellation (CVT) is a special type of Voronoi tessellation in which the generating point of each Voronoi cell is also its centroid (center of mass). It can be viewed as an optimal partition corresponding to an optimal distribution of generators. A number of algorithms can be used to generate centroidal Voronoi tessellations, including Lloyd's algorithm for K-means clustering or Quasi-Newton methods like Broyden–Fletcher–Goldfarb–Shanno algorithm, BFGS. Proofs Gersho's conjecture, proven for one and two dimensions, says that "asymptotically speaking, all cells of the optimal CVT, while forming a tessellation, are Congruence (geometry), congruent to a basic cell which depends on the dimension." In two dimensions, the basic cell for the optimal CVT is a regular hexagon as it is proven to be the most dense Circle packing, packing of circles in 2D Euclidean space. Its three dimensional equivalent is the rhombic dodecahedral honeycomb, derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver chuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, construction and utility projects. Specially designed versions are made for miniature applications. History Around 35,000 BC, '' Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earliest perforated artifacts, such as bone, ivory, shells, a ...
