Fr.: interaction fondamentale
Any of the four interactions in nature between bodies of matter and that are mediated by one or more particles. Also called the → fundamental force.

→ one, + -idan infinitive suffix.
1, 2, 3) iveš; 3) godâz (#)
1) The act or process of fusing; the state of being
→ fused; that which is fused; the result of fusing.
From M.Fr. fusion, from L. fusionem, from fusus, p.p. of fundere "to pour, melt."
Verbal noun form of → fuse.
General: Time that is to be or come hereafter.
M.E. futur, from O.Fr., from L. futurus "about to be," irregular suppletive future participle of esse "to be."
Âyandé "future" agent noun/adjective of âmadan "to come, to occur, to become," from Mid.Pers. âmatan; O.Pers. gam- "to come; to go," Av. gam- "to come; to go," jamaiti "goes;" Proto-Iranian *āgmatani; Skt. gamati "goes;" Gk. bainein "to go, walk, step;" L. venire "to come;" Tocharian A käm- "to come;" O.H.G. queman "to come;" E. come; PIE root *gwem- "to go, come."
future light cone
maxrut-e nuri-ye âyandé (#)
Fr.: cône de lumière futur
The set of all points in a → space-time diagram that are reached by signals travelling from a specified point at the speed of light.
Fr.: duvet, poils fins
1) Loose, light, fibrous, or → fluffy matter.
Of unknown origin; cf. Du. voos "spongy, woolly."
Porz "short fuzzy ends of fibers on the surface of cloth, any downy coating," of unknown etymology.
The first step carried out in a → fuzzy logic system during which a → crisp set of → input data are gathered and converted to a → fuzzy set using fuzzy → linguistic variables, fuzzy linguistic terms, and → membership functions.
The state or condition of being → fuzzy.
Fr.: flou, crépu
Fr.: image floue, ~ estompée
Same as → blurred image.
fuzzy inference system
râžmân-e darbord-e porzvâr
A way of → mapping an → input space to an → output space using → fuzzy logic. FIS uses a collection of fuzzy → membership functions and rules, instead of Boolean logic, to reason about data. Also called → fuzzy logic system.
A process used in a → fuzzy logic system where the → truth value for the premise of each rule is computed and applied to the conclusion part of each rule. This results in one fuzzy set to be assigned to each output variable for each rule.
Fr.: logic flou
A mathematical logic that recognizes more than simple → true and → false → propositions. With fuzzy logic, propositions can be represented with degrees of truthfulness and falsehood. In this system, → truth values are → fuzzy sets without sharp boundaries (→ crisp set) in contrast with → classical logic. Fuzzy logic is applied to a wide range of problems including: industrial control, domestic goods, decision making, robotics, intelligent machines, and image processing in medicine.
fuzzy logic system
râžmân-e guyik-e porzvâr
Fr.: système de logic flou
An engineering system which uses → fuzzy logic. It generally consists of four main components: → fuzzification interface (fuzzifier), → fuzzy rule base, → fuzzy inferencing unit, and → defuzzification interface (difuzzifier). Also called → fuzzy inference system.
