The idea of Cognitive radio was first presented officially in the article by Joseph Mitola III and Gerald Q. Maguire, Jr. [1]. It was a novel approach for wireless communication that Mitola III later described as "the point in which wireless personal digital assistants (PDAs) and the related networks are sufficiently computationally intelligent about radio resources and related computer-to-computer communications to detect user communications needs as a function of use context, and to provide radio resources and wire less services most ap ...

In theoretical physics, the Brans-Dicke theory of gravitation (sometimes called the Jordan-Brans-Dicke theory) is a well-known competitor of Einstein's theory of general relativity. The theory was developed by Robert H. Dicke and Carl H. Brans, building upon earlier work of Pascual Jordan. At present, both general relativity and the Brans-Dicke theory are compatible with all well accepted observational and experimental evidence. Brans-Dicke theory - Comparison with general relativity.

Homeostasis is the property of an open system, especially living organisms, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms. The term was coined in 1932 by Walter Cannon from the Greek homo (same, like) and stasis (to stand, posture). Homeostasis - Overview. The term is most often used in the sense of biological homeostasis. Multicellular organisms require a hom ...

Risk is the potential harm that may arise from some present process or from some future event. In everyday usage, "risk" is often used synonymously with "probability", but in professional risk assessments, risk combines the probability of a negative event occurring with how harmful that event would be. Thus in many engineering applications (see 2.1 below) Risk = probability of an accident/'event' (eg events per year) times its consequence (eg lost money, ... or deaths, per event).

Stratification is the building up of layers of deposits, and can have several variations of meaning: Social stratification, is the dividing of a society into levels based on wealth or power. Stratification in archaeology are the layers in which objects are found. Stratification (botany). See stratified sampling for the use of stratification in survey sampling. The term "stratified sampling" is also refers a method of variance reduction in Monte Carlo methods. In logic, stratifica

Evangelism is the preaching of the Christian Gospel or, by extension, any other form of preaching or proselytizing. The word evangelist comes from the Koine Greek word εὐάγγελος ("eu-angelos"), meaning bringer of good news. The Koine expression for good news, εὐάγγελιον ("eu-angelion") is used to refer to the four Gospels in the New Testament; and thus the Evangelists are also the authors of the four Gospels -- traditionally known as Matthew, Mark, Luke, and John.

Cognitive radio is a paradigm for wireless communication in which either network or wireless node itself changes particular transmission or reception parameter to fulfill specific tasks. This parameter alteration is based on observations of various factors from external and internal cognitive radio environment, like radio frequency spectrum, user behaviour, network state etc..

An attribute is the following: Generally, an attribute is an abstraction characteristic of an entity In art an "attribute" is an object that identifies a figure; most commonly it refers to objects held by saints in religious paintings that indicate which saint is being represented.

In thermodynamics, a phase is a region of space where matter lies in a given physical configuration, like for example of a liquid phase, or a solid phase, etc. Note that the phase space of thermodynamics, which is the parameter space in which one describes the phases of a system is also a phase space in the mathematical sense of the term, because it is the space of thermodynamic (macroscopic) parameters, like pressure and temperature. In statistical mechanics, a domain which focuses on predicting the thermodynamic ...

Consider a sample of size N drawn from a normal distribution of mean μ and unit variance (i.e., ). The sample mean, , of the sample , defined as has variance . This is equal to the reciprocal of the Fisher information from the sample (this is clear from the definition) and thus, by the Cramér-Rao inequality, the sample mean is effici ...

Given two spaces X and Y, we say they are homotopy equivalent or of the same homotopy type if there exist continuous maps f : X → Y and g : Y → X such that g o f is homotopic to the identity map idX and f o g is homotopic to idY. The maps f and g are called homotopy equivalences in this case. Clearly, every homeomorphism is a homotopy equivalence, but the converse is not tru ...

In the limiting case where is a large number, the deduction distribution of tends towards the binomial distribution with the probability as a parameter, and the induction distribution of tends towards the beta distribution (The frequency probability solution to this problem is : the probability is estimated by the relative frequency.)

A minimax algorithm is a recursive algorithm for choosing the next move in a two-player game. A value is associated with each position or state of the game. This value is computed by means of a position evaluation function and it indicates how good it would be for a player to reach that position. The player then makes the move that maximises the minimum value of the position resulting from the opponent's possible following moves. If it is A' ...

The physical dimensions are the parameters required to answer to the question where and when happened or will happen some event; for instance: When did Napoleon die? — On the 5 May 1821 at Saint Helena (15°56′ S 5°42′ W). They play a fundamental role in our perception of the world around us. According to Immanuel Kant, we actually do not perceive them but they form the frame in which we perceive events; they form the a priori background in which events are perceived. ...

Confidence levels are typically given alongside statistics resulting from sampling. In a statement: we are 95% confident that between 35% and 45% of voters favor Candidate A, 95% is our confidence level and 35%-45% is our confidence interval. It is very tempting to misunderstand this statement in the following way. We used capital letters U and V for random variables; it is conventional to use lower-case letters u and v for their observed values in a particu ...
