121Ultra exponential function — Articleissues OR=January 2008 other=This article uses nonstandard notations, which are confusing and superfluous.In mathematics the ultra exponential function is a special case of the iterated exponential function more commonly known as tetration …
122Dickman function — The Dickman–de Bruijn function ρ(u) plotted on a logarithmic scale. The horizontal axis is the argument u, and the vertical axis is the value of the function. The graph nearly makes a downward line on the logarithmic scale, demonstrating that the …
123Bessel function — Math. one of several transcendental functions, usually represented as power series, that are solutions to a group of related differential equations. [1870 75; named after F. W. BESSEL] * * * ▪ mathematics also called Cylinder Function, … …
124Artin-Mazur zeta function — In mathematics, the Artin Mazur zeta function is a tool for studying the iterated functions that occur in dynamical systems and fractals.It is defined as the formal power series :zeta f(z)=exp sum {n=1}^infty extrm{card} left( extrm{Fix} (f^n)… …
125Ramp function — The ramp function is an elementary unary real function, easily computable as the mean of its independent variable and its absolute value.This function is applied in engineering (e.g., in the theory of DSP). The name ramp function can be derived… …
126Modulation transfer function (infrared imaging) — The Modulation Transfer Function (MTF) is used to approximate the position of best focus of an infrared imaging system. In an imaging system, best focus is typically achieved when the MTF is between 0.4 and 0.6; most often at 0.5 (50% cutoff… …
127Singular function — The graph of the winding number of the circle map is an example of a singular function. In mathematics, a singular function is any function ƒ defined on the interval [a, b] that has the following properties: ƒ is continuous on [a, b]. (**) there… …
128Boolean function — In mathematics, a (finitary) Boolean function is a function of the form f : B k rarr; B, where B = {0, 1} is a Boolean domain and k is a nonnegative integer called the arity of the function. In the case where k = 0, the function is essentially a… …
