Fuzzing

Fuzzing, or fuzz testing, is an automated software testing technique that feeds programs large numbers of malformed inputs and monitors for crashes, hangs, and memory errors.

Fuzzy cognitive map

A fuzzy cognitive map (FCM) is a graph-based modeling method in which weighted, signed causal links connect concepts and simulations support decision making in complex systems.

Fuzzy cognitive mapping

Fuzzy cognitive mapping is a modeling method that represents concepts and weighted causal relationships as a graph, simulating how activation spreads to support scenario analysis and decisions.

Fuzzy entropy

Fuzzy entropy is a measure of the degree of fuzziness of a fuzzy set, defined by De Luca and Termini in 1972 without reference to probability.

Fuzzy inference system

A fuzzy inference system is a computational method that maps inputs to outputs through if-then rules over fuzzy sets, used in control systems such as cement kilns since 1978.

Fuzzy k-means clustering

Fuzzy k-means clustering, also called fuzzy c-means, is a soft clustering algorithm that assigns each data point fractional memberships in every cluster rather than one hard label.

Fuzzy linear programming

Fuzzy linear programming (FLP) treats the parameters, constraints, or objectives of linear programming models as fuzzy, so constraints and goals are satisfied to varying degrees.

Fuzzy PID control

Fuzzy PID control is a control engineering method that uses fuzzy logic rules to adjust the gains of a PID controller online, or to build a nonlinear PID directly from fuzzy rules.

Fuzzy rough sets

Fuzzy rough sets are a hybrid mathematical model combining fuzzy set theory's graded membership with rough set theory's approximations, introduced by Dubois and Prade in 1990 and used mainly for feature selection.

Fuzzy time series

Fuzzy time series is a forecasting method, introduced by Song and Chissom in the early 1990s, whose observations are fuzzy sets or linguistic values rather than crisp numbers.

FV101 Scorpion

The FV101 Scorpion is a British light tank that led the seven-vehicle CVR(T) family, serving from 1973 to 1994 and fighting in the Falklands and Gulf wars.

FV107 Scimitar

The FV107 Scimitar, also known as the Alvis Scimitar, was a British light reconnaissance tank armed with a 30 mm cannon, in service from 1971 to 2023.

FV432

The FV432 is a British tracked armored personnel carrier, the most common variant of the FV430 series, built by GKN Sankey and in service from 1963.

FX-05 Xiuhcoatl

The FX-05 Xiuhcoatl, also known as the FX-05, is Mexico's indigenously designed 5.56×45 mm NATO assault rifle, adopted to replace the Heckler & Koch G3 in Mexican Army service.

FxLMS algorithm

The FxLMS algorithm is an adaptive control algorithm for active noise control, filtering its reference signal through an estimate of the secondary path to remain stable.

FxPro

FxPro is a London-headquartered online broker offering CFDs on forex, stocks, indices, metals, and cryptocurrencies, serving clients in more than 170 countries through UK-, Cyprus-, and Bahamas-regulated entities.

FZG gear test

The FZG gear test is a standardized gear-rig test developed at the Technical University of Munich's Gear Research Centre, best known for rating lubricating oils by scuffing resistance.

G-code

G-code is a language of preparatory G and miscellaneous M codes used to program CNC machine tools and 3D printers, standardized as ISO 6983 and DIN 66025.

G-EO

The G-EO is a stationary end-effector robotic gait trainer made by Reha Technology AG of Olten, Switzerland, using programmable footplates to simulate walking and stair climbing in rehabilitation.

G-LOC

G-LOC, or G-induced loss of consciousness, is unconsciousness in pilots of high-performance aircraft caused by sustained G forces draining blood from the head, leaving about 28 seconds of incapacitation.

G-Shock

G-Shock, also known as Casio G-Shock, is a line of shock-resistant wristwatches made by the Japanese company Casio. Its first model, the DW-5000C, was released in 1983.

G-spot vibrator

A G-spot vibrator is a sex toy with a curved or angled, vibrating shaft designed to stimulate the Gräfenberg spot, a contested erogenous area on the front vaginal wall.

G-suit

A G-suit, also called an anti-G suit, is a garment worn by aviators and astronauts that squeezes the legs and abdomen to prevent blackout during high acceleration.
