requirements of direct access of state spaces of large or variable-length keys. Use of hash functions relies on statistical properties of key and function interaction:...

continuation function is represented as a parameter named "k": In the CPS versions, the primitives used, like +& and *& are themselves CPS, not direct style...

equation relates the pair correlation function to the direct correlation function. The direct correlation function is only used in connection with the OZ...

(1969). In this earlier model, supply (specifically labor supply) is a direct function of real wages: more work will be done when real wages are high and...

rotation. The Gudermannian function gives a direct relationship between the circular functions and the hyperbolic functions that does not involve complex...

male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization...

another form of direct democracy, consisting of an assembly open to everyone within a local area or entity. Their roles and functioning have varied throughout...

In mathematics, the exponential function is the unique real function which maps zero to one and has a derivative equal to its value. The exponential of...

transmitted or not. Imperfections in the optics typically have a direct effect on the pupil function, it is therefore an important tool to study optical imaging...

standard sea level values. It so happens that the speed of sound is a direct function of temperature, so instead of a standard temperature, we can define...

Direct costs, in accounting, are costs directly accountable to a cost object (such as a particular project, facility, function, or product). The equivalent...

In quantum physics, a wave function (or wavefunction) is a mathematical description of the quantum state of an isolated quantum system. The most common...

analytic function is a function that is locally given by a convergent power series. There exist both real analytic functions and complex analytic functions. Functions...

In mathematics, an even function is a real function such that f ( − x ) = f ( x ) {\displaystyle f(-x)=f(x)} for every x {\displaystyle x} in its domain...

In mathematics, theta functions are special functions of several complex variables. They show up in many topics, including Abelian varieties, moduli spaces...

a transfer function (also known as system function or network function) of a system, sub-system, or component is a mathematical function that models...

Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through...

In mathematics, a monotonic function (or monotone function) is a function between ordered sets that preserves or reverses the given order. This concept...

{\displaystyle \circ } takes two functions, f {\displaystyle f} and g {\displaystyle g} , and returns a new function h ( x ) := ( g ∘ f ) ( x ) = g (...

of a function is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point. For most common functions, the...
