Ground Potential Rise
In electrical engineering, earth potential rise (EPR), also called ground potential rise (GPR), occurs when a large electric current, current flows to earth through an earth grid electrical impedance, impedance. The potential relative to a distant point on the Earth is highest at the point where current enters the ground, and declines with distance from the source. Ground potential rise is a concern in the design of electrical substations because the high potential may be a hazard to people or equipment. The change of voltage over distance (potential gradient) may be so high that a person could be injured due to the voltage developed between two feet, or between the ground on which the person is standing and a metal object. Any conducting object connected to the substation earth ground, such as telephone wires, rails, fences, or metallic piping, may also be energized at the ground potential in the substation. This transferred potential is a hazard to people and equipment outside the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaussian Process Regression
In statistics, originally in geostatistics, kriging or Kriging (), also known as Gaussian process regression, is a method of interpolation based on Gaussian process governed by prior covariances. Under suitable assumptions of the prior, kriging gives the best linear unbiased prediction (BLUP) at unsampled locations. Interpolating methods based on other criteria such as smoothness (e.g., smoothing spline) may not yield the BLUP. The method is widely used in the domain of spatial analysis and computer experiments. The technique is also known as Wiener–Kolmogorov prediction, after Norbert Wiener and Andrey Kolmogorov. The theoretical basis for the method was developed by the French mathematician Georges Matheron in 1960, based on the master's thesis of Danie G. Krige, the pioneering plotter of distance-weighted average gold grades at the Witwatersrand reef complex in South Africa. Krige sought to estimate the most likely distribution of gold based on samples from a few borehole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General-purpose Register
A processor register is a quickly accessible location available to a computer's processor. Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only. In computer architecture, registers are typically addressed by mechanisms other than main memory, but may in some cases be assigned a memory address e.g. DEC PDP-10, ICT 1900. Almost all computers, whether load/store architecture or not, load items of data from a larger memory into registers where they are used for arithmetic operations, bitwise operations, and other operations, and are manipulated or tested by machine instructions. Manipulated items are then often stored back to main memory, either by the same instruction or by a subsequent one. Modern processors use either static or dynamic random-access memory (RAM) as main memory, with the latter usually accessed via one or more cache levels. Processor registers are norm ...

G-protein Coupled Receptor
G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large protein family, group of evolutionarily related proteins that are cell surface receptors that detect molecules outside the cell (biology), cell and activate cellular responses. They are coupled with G proteins. They pass through the cell membrane seven times in the form of six loops (three extracellular loops interacting with ligand molecules, three intracellular loops interacting with G proteins, an N-terminus, N-terminal extracellular region and a C-terminal intracellular region) of amino acid residues, which is why they are sometimes referred to as seven-transmembrane receptors.

Ground-penetrating Radar
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. This nondestructive method uses electromagnetic radiation in the microwave band ( UHF/ VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks. GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter and antenna emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Practice Residency
There are two forms of institution-based training for general dentistry available for dental school graduates in the United States: * General practice residency (GPR) * Advanced education in general dentistry (AEGD) Program details Both GPRs and AEGDs can be 1-year programs with an option available to continue for a second year or they may be a two-year program from the start. They allow the new dentist to further hone his or her skills in most of the traditionally defined disciplines of dentistry while at the same time increasing one's speed and refining one's techniques. These programs also afford trainees the opportunity to learn from the attending dentists who serve a supervisory role, something generally unavailable in private practice. While a GPR is a hospital-based program, an AEGD is usually not and the differences between the two types of programs are generally a result of this distinction. Both types of programs afford the trainee with a larger patient pool than he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georgia Public Radio
Georgia Public Broadcasting (GPB) is a state network of PBS member television stations and NPR member radio stations serving the U.S. state of Georgia. It is operated by the Georgia Public Telecommunications Commission, an agency of the Georgia state government which holds the licenses for most of the PBS and NPR member stations licensed in the state. The broadcast signals of the nine television stations and 19 radio stations cover almost all of the state, as well as parts of Alabama, Florida, North Carolina, South Carolina and Tennessee. The network's headquarters and primary radio and television production facilities are located on 14th Street in Midtown Atlanta, just west of the Downtown Connector in the Home Park neighborhood. The facility and GPB are also a major part of Georgia's film and television industry, and in addition to commercial production occurring at the GPB facilities, some production companies also rent production offices from GPB.

Glider Pilot Regiment
The Glider Pilot Regiment was a British airborne forces unit of the Second World War, which was responsible for crewing the British Army's military gliders and saw action in the European theatre in support of Allied airborne operations. Established during the war in 1942, the regiment was disbanded in 1957. During its short existence, the unit gained the dual distinction of being both the shortest-lived regiment in British Army history and the unit that accrued the highest casualty rate per head. Formation The German military was one of the pioneers of the use of airborne formations, conducting several successful airborne operations during the Battle of France in 1940, including the Battle of Fort Eben-Emael. Impressed by the success of German airborne operations, the Allied governments decided to form their own airborne formations. This decision would eventually lead to the creation of two British airborne divisions, as well as a number of smaller units. The British airborne es ...
