Tethering
Tethering or phone-as-modem (PAM) is the sharing of a mobile device's cellular data connection with other connected computers. It effectively turns the transmitting device into a modem to allow others to use its cellular network as a gateway for Internet access. The sharing can be done wirelessly over wireless LAN (Wi-Fi), Bluetooth, IrDA or by physical connection using a cable like USB. If tethering is done over Wi-Fi, the feature may be branded as a personal hotspot or mobile hotspot, and the transmitting mobile device would also act as a portable wireless access point (AP) which may also be protected using a password. Tethering over Bluetooth may use the Personal Area Networking (PAN) profile between paired devices, or alternatively the Dial-Up Networking (DUN) profile where the receiving device virtually dials the cellular network APN, typically using the number ''*99''#. Mobile devices' OS support Many mobile devices are equipped with software to offer tethered Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airport Hot Spots
An airport is an aerodrome with extended facilities, mostly for commercial air transport. They usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Airport operations are extremely complex, with a complicated system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Spot (cricket)
Hot Spot is an infra-red, infrared imaging system used in cricket to determine whether the ball has struck the batsman, bat or pad. Hot Spot requires two infrared cameras on opposite sides of the ground above the field of play that are continuously recording an image. Any suspected nick or bat/pad event can be verified by examining the infrared image, which usually shows a bright spot where contact friction from the ball has elevated the local temperature. Where referrals to an off-field third umpire are permitted, the technology is used to enhance the on-field umpire's decision-making accuracy. Where referrals are not permitted, the technology is used primarily as an analytical aid for television coverage. Use The system's principal application in cricket is in deciding whether the ball has struck the batsman's bat or pad – this determination being critical in determining if a batsman is Dismissal (cricket), out or not out, not on Appeal (cricket), appeal for Leg bef ...

Hot Spot (casting)
A casting defect is an undesired irregularity in a casting (metalworking), metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. They are broken down into five main categories: ''gas porosity'', ''shrinkage defects'', ''mould material defects'', ''pouring metal defects'', and ''metallurgical defects''. Terminology The terms "defect" and "" refer to two specific and separate things in castings. Defects are defined as conditions in a casting that must be corrected or removed, or the casting must be rejected. Discontinuities, also known as "imperfections", are defined as "interruptions in the physical continuity of the casting". Therefore, if the casting is less than perfect, but still useful and in tolerance, the imperfections should be deemed "discontinuities". Types There are many types of defects which result from many different causes. Some of the solutions to certain defects can be the cause for another type of de ...

Airport Diagram
Airport diagrams, airport charts, or aerodrome charts are airport maps that are designed to assist ground traffic to move around complex runway and taxiway configurations. Regulation International Civil Aviation Organization (ICAO) Annex 4 "Aeronautical Charts" Chapter 13 "Aerodrome/Heliport Chart" specifies that the chart "shall provide flight crews with information which information which will facilitate the ground movement of aircraft" between the aircraft stand and the runway. For helicopter movement, the chart shall provide information between the helicopter stand, the touchdown and lift-off area, and the final approach and take-off area; the chart should also supplement information along helicopter ground and air taxiways and air transit routes. In addition, essential operational information should also be provided. Content According to ICAO, airport diagrams shall show coordinates, field elevations, runways, Airport apron, aprons, taxiways, hot spots, taxiway routes, ai ...

Recombination Hotspot
Recombination hotspots are regions in a genome that exhibit elevated rates of recombination relative to a neutral expectation. The recombination rate within hotspots can be hundreds of times that of the surrounding region. Recombination hotspots result from higher DNA break formation in these regions, and apply to both mitotic and meiotic cells. This appellation can refer to recombination events resulting from the uneven distribution of programmed meiotic double-strand breaks. Meiotic recombination Meiotic recombination through crossing over is thought to be a mechanism by which a cell promotes correct segregation of homologous chromosomes and the repair of DNA damages. Crossing over requires a DNA double-stranded break followed by strand invasion of the homolog and subsequent repair. Initiation sites for recombination are usually identified by mapping crossing over events through pedigree analysis or through analysis of linkage disequilibrium. Linkage disequilibrium has iden ...

Hot Spot Effect In Subatomic Physics
Hot spots in subatomic physics are regions of high energy density or temperature in hadronic or nuclear matter. Finite size effects Hot spots are a manifestation of the finite size of the system: in subatomic physics this refers both to atomic nuclei, which consist of nucleons, as well as to nucleons themselves, which are made of quarks and gluons, Other manifestations of finite sizes of these systems are seen in scattering of electrons on nuclei and nucleons. For nuclei in particular finite size effects manifest themselves also in the isomeric shift and isotopic shift. Statistical methods in subatomic physics The formation of hot spots assumes the establishment of local equilibrium, which in its turn occurs if the thermal conductivity in the medium is sufficiently small. The notions of equilibrium and heat are statistical. The use of statistical methods assumes a large number of degrees of freedom. In macroscopic physics this number usually refers to the number of atoms or molec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Hotspot
A biodiversity hotspot is a ecoregion, biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into "Hotspots: Earth's Biologically Richest and Most Endangered Terrestrial Ecoregions" and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as Endemism, endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hots ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of Radioactive decay, radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants produces ionizing radiation (namely alpha particle, alpha, beta particle, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Spot (veterinary Medicine)
Pyotraumatic dermatitis, also known as a hot spot or acute moist dermatitis, is a common infection of the skin surface of dogs, particularly those with thick or long coats. It occurs following self-inflicted trauma of the skin. Pyotraumatic dermatitis rarely affects cats. Signs The dog persistently licks, chews, scratches or rubs at a focal area of skin, which quickly causes hair loss. The skin becomes red, moist and weeps. The affected area is obviously defined and separate from the surrounding healthy skin and coat. Usually only one area of the skin is affected. The size of the affected area is variable. If the area is difficult for the dog to scratch, or if the disease is caught early, hair may still be present. Areas commonly affected include the rump above the tail, the head and neck near the ears, and the top and sides of the lumbar area. Cause Pyotraumatic dermatitis is caused by self-inflicted trauma to the skin, which is incited by pain or irritation, such as infestation ...

Hotspot (geology)
In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying Mantle (geology), mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii hotspot, Hawaii, Iceland hotspot, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of plate boundary, tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. The alternative plate theory (volcanism), plate theory is that the mantle source beneath a hotspot is not anomalously hot, rather the crust above is unusually weak or thin, so that lithospheric extension permits the passive rising of melt from shallow depths. Origin The origins of the concept of hotspots lie in the work of J. Tuzo Wilson, who postulated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
