Feige–Fiat–Shamir Identification Scheme
In cryptography, the Feige–Fiat–Shamir identification scheme is a type of parallel zero-knowledge proof developed by Uriel Feige, Amos Fiat, and Adi Shamir in 1988. Like all zero-knowledge proofs, it allows one party, the Prover, to prove to another party, the Verifier, that they possess secret information without revealing to Verifier what that secret information is. The Feige–Fiat–Shamir identification scheme, however, uses modular arithmetic and a parallel verification process that limits the number of communications between Prover and Verifier. Setup Following a common convention, call the prover Peggy and the verifier Victor. Choose two large prime integers ''p'' and ''q'' and compute the product ''n = pq''. Create secret numbers s_1, \cdots, s_k coprime In mathematics, two integers and are coprime, relatively prime or mutually prime if the only positive integer that is a divisor of both of them is 1. Consequently, any prime number that divides does not divi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fee-for-service
Fee-for-service (FFS) is a payment model where services are unbundled and paid for separately. In health care, it gives an incentive for physicians to provide more treatments because payment is dependent on the quantity of care, rather than quality of care. However evidence of the effectiveness of FFS in improving health care quality is mixed, without conclusive proof that these programs either succeed or fail. Similarly, when patients are shielded from paying (cost-sharing) by health insurance coverage, they are incentivized to welcome any medical service that might do some good. Fee-for-services raises costs, and discourages the efficiencies of integrated care. A variety of reform efforts have been attempted, recommended, or initiated to reduce its influence (such as moving towards bundled payments and capitation). In capitation, physicians are not incentivized to perform procedures, including necessary ones, because they are not paid anything extra for performing them. FFS is t ...

Farmer Field School
A farmer field school (FFS) is a group-based learning process that has been used by a number of governments, NGOs, and international agencies to promote integrated pest management (IPM). The first FFSs were designed and managed by the UN Food and Agriculture Organization in Indonesia in 1989. Since then, more than two million farmers across Asia have participated in this type of learning. A farmer field school brings together concepts and methods from agroecology, experiential education and community development. As a result, hundreds of thousands of rice farmers in countries such as China, India, Indonesia, Philippines and Vietnam have been able to reduce the use of pesticides and improve the sustainability of crop yields. FFSs have also produced other developmental benefits that are broadly described as 'empowerment': FFS alumni in a number of countries are involved in a wide range of self-directed activities including research, training, marketing, and advocacy.

Full Flight Simulator
Full flight simulator (FFS) is a term used by national (civil) aviation authorities (NAA) for a high technical level of flight simulator. Such authorities include the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA). There are currently four levels of full flight simulator, levels A through D, with level D being the highest standard and being eligible for zero flight time (ZFT) training of civil pilots when converting from one airliner type to another. In about 2012, these FFS levels will be changed as a result of work by an international working group chaired by the UK Royal Aeronautical Society Flight Simulation Group (RAeS FSG), which rationalised 27 previous categories of flight training device into 7 international ones. This work has been accepted by ICAO and is published under ICAO document 9625 Issue 3. The new Type 7 Full Flight Simulator will be the old Level D with enhancements in a number of areas including motio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fringe Field Switching
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free-fall Sensor
An accelerometer is a tool that measures proper acceleration. Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame; this is different from coordinate acceleration, which is acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards (by definition) of g ≈ 9.81 m/s2. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero. Accelerometers have many uses in industry and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. Vibration in rotating machines is monitored by accelerometers. They are used in tablet computers and digital cameras so that images on screens are always displayed upright. In unmanned aerial vehicles, accelerometers help to stabilise flight. W ...

Facial Feminization Surgery
Facial feminization surgery (FFS) is a set of reconstructive surgical procedures that alter typically male facial features to bring them closer in shape and size to typical female facial features. FFS can include various bony and soft tissue procedures such as brow lift, rhinoplasty, cheek implantation, and lip augmentation. Faces contain secondary sex characteristics that make male and female faces readily distinguishable, including the shape of the forehead, nose, lips, cheeks, chin, and jawline; the features in the upper third of the face seem to be the most important, and subtle changes in the lips can have a strong effect. Candidates For some transgender women, FFS is medically necessary to treat gender dysphoria. It can be just as important or even more important than genital forms of sex reassignment surgery (SRS) in reducing gender dysphoria and helping trans women integrate socially as women; data on these sorts of outcomes are limited by small study size and confoundi ...

French Frigate Shoals
The French Frigate Shoals ( Hawaiian: Kānemilohai) is the largest atoll in the Northwestern Hawaiian Islands. Its name commemorates French explorer Jean-François de La Pérouse, who nearly lost two frigates when attempting to navigate the shoals. It consists of a crescent-shaped reef, twelve sandbars, and the La Perouse Pinnacle, the only remnant of its volcanic origins. The total land area of the islets is . Total coral reef area of the shoals is over . Tern Island, with an area of , has a landing strip and permanent habitations for a small number of people. It is maintained as a field station in the Hawaiian Islands National Wildlife Refuge by the United States Fish and Wildlife Service. The French Frigate Shoals are about northwest of Honolulu. In the 20th century, the shoals were used by the Imperial Japanese Navy as part of an operation to attack Hawaii; afterwards, a small United States Navy base was established there to prevent it from being used again. After th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swiss Federal Railways
Swiss Federal Railways (german: link=no, Schweizerische Bundesbahnen, ''SBB''; french: link=no, Chemins de fer fédéraux suisses, ''CFF''; it, Ferrovie federali svizzere, ''FFS'') is the national railway company of Switzerland. It is usually referred to by the initials of its German, French, and Italian names, either as SBB CFF FFS, or used separately. The Romansh version of its name, ''Viafiers federalas svizras'', is not officially used. The official English abbreviation is "SBB", instead of the English acronym such as "SFR", which stands for ''Swiss Federal Railways'' itself. The company, founded in 1902, is headquartered in Bern. It used to be a government institution, but since 1999 it has been a special stock corporation whose shares are held by the Swiss Confederation and the Swiss cantons. It is currently the largest rail and transport company of Switzerland, and operates on most standard gauge lines of the Swiss network. It also heavily collaborates with ...
