71Choice function — A choice function (selector, selection) is a mathematical function f that is defined on some collection X of nonempty sets and assigns to each set S in that collection some element f(S) of S. In other words, f is a choice function for X if and… …
72Riesz function — In mathematics, the Riesz function is an entire function defined by Marcel Riesz in connection with the Riemann hypothesis, by means of the power series:{ m Riesz}(x) = sum {k=1}^infty frac{( x)^k}{(k 1)! zeta(2k)}If we set F(x) = frac12 { m… …
73Head-related transfer function — The head related transfer function HRTF , also called the anatomical transfer function ATF , describes how a given sound wave input (parameterized as frequency and source location) is filtered by the diffraction and reflection properties of the… …
74Constructible function — In complexity theory, a time constructible function is a function f from natural numbers to natural numbers with the property that f(n) can be constructed from n by a Turing machine in the time of order f(n). The purpose of such a definition is… …
75store door function — n. a lockset function in which: a) a deadbolt is operated by key from either side and a latch is operated by working trim from either side; or b) a deadlocking latch can be withdrawn by working trim from either side except when both sides… …
76inverse function — noun a function obtained by expressing the dependent variable of one function as the independent variable of another; f and g are inverse functions if f(x)=y and g(y)=x (Freq. 1) • Hypernyms: ↑function, ↑mathematical function, ↑single valued… …
77Foreign function interface — A foreign function interface (or abbr|FFI|Foreign Function Interface) is a mechanism by which a program written in one programming language can call routines or make use of services written in another. The term comes from the specification for… …
78God's utility function — is a phrase coined by Richard Dawkins in his book River Out of Eden. God s utility function is the third chapter in this book. Dawkins uses this phrase to expound the Gene centered view of evolution by equating the phrase to the meaning of life… …
79Terminal function — A terminal function is a function (node) in a parse tree which is a leaf in that parse tree. Background A parse tree is made up of nodes and branches. In the picture below the parse tree is the entire structure, starting from S and ending in each …
80Dimension function — In mathematics, the notion of an (exact) dimension function (also known as a gauge function) is a tool in the study of fractals and other subsets of metric spaces. Dimension functions are a generalisation of the simple diameter to the dimension… …
