Circular Error Probable In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability[1]) is a measure of a weapon system's precision. It is defined as the radius of a circle, centered on the mean, whose boundary is expected to include the landing points of 50% of the rounds.[2][3] That is, if a given bomb design has a CEP of 100 metres (330 ft), when 100 are targeted at the same point, 50 will fall within a 100 m circle around their average impact point. (The distance between the target point and the average impact point is referred to as bias.)Contents1 Concept 2 Conversion between CEP, DRMS, 2DRMS, and R95 3 Use in popular culture 4 See also 5 References 6 Further reading 7 External linksConcept[edit]20 hits distribution exampleThe original concept of CEP was based on a circular bivariate normal distribution (CBN) with CEP as a parameter of the CBN just as μ and σ are parameters of the normal distribution [...More...]  "Circular Error Probable" on: Wikipedia Yahoo 

Pendulum A pendulum is a weight suspended from a pivot so that it can swing freely.[1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period [...More...]  "Pendulum" on: Wikipedia Yahoo 

Covariance In probability theory and statistics, covariance is a measure of the joint variability of two random variables.[1] If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values, (i.e., the variables tend to show similar behavior), the covariance is positive.[2] In the opposite case, when the greater values of one variable mainly correspond to the lesser values of the other, (i.e., the variables tend to show opposite behavior), the covariance is negative. The sign of the covariance therefore shows the tendency in the linear relationship between the variables. The magnitude of the covariance is not easy to interpret because it is not normalized and hence depends on the magnitudes of the variables [...More...]  "Covariance" on: Wikipedia Yahoo

Clear And Present Danger (film) Clear and Present Danger Clear and Present Danger is a 1994 American spy thriller film directed by Phillip Noyce[2] and based on Tom Clancy's novel of the same name. It was preceded by the 1990 film The Hunt for Red October The Hunt for Red October and the 1992 film Patriot Games, all three featuring Clancy's character Jack Ryan. It is the last film version of Clancy's novels to feature Harrison Ford as Ryan and James Earl Jones James Earl Jones as Vice Admiral James Greer, as well as the final installment directed by Noyce. As in the novel, Ryan is appointed CIA Acting Deputy Director, and discovers he is being kept in the dark by colleagues who are conducting a covert war against a drug cartel in Colombia, apparently with the approval of the President [...More...]  "Clear And Present Danger (film)" on: Wikipedia Yahoo 

Root Mean Square In statistics and its applications, the root mean square (abbreviated RMS or rms) is defined as the square root of the mean square (the arithmetic mean of the squares of a set of numbers).[1] The RMS is also known as the quadratic mean and is a particular case of the generalized mean with exponent 2 [...More...]  "Root Mean Square" on: Wikipedia Yahoo 

Circle A circle is a simple closed shape. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius. This article is about circles in Euclidean geometry, and, in particular, the Euclidean plane, except where otherwise noted. A circle is a simple closed curve which divides the plane into two regions: an interior and an exterior [...More...]  "Circle" on: Wikipedia Yahoo 

Radius In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin Latin radius, meaning ray but also the spoke of a chariot wheel.[1] The plural of radius can be either radii (from the Latin Latin plural) or the conventional English plural radiuses.[2] The typical abbreviation and mathematical variable name for radius is r. By extension, the diameter d is defined as twice the radius:[3] d ≐ 2 r ⇒ r = d 2 . displaystyle ddoteq 2rquad Rightarrow quad r= frac d 2 . If an object does not have a center, the term may refer to its circumradius, the radius of its circumscribed circle or circumscribed sphere [...More...]  "Radius" on: Wikipedia Yahoo 

Variance In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. Informally, it measures how far a set of (random) numbers are spread out from their average value. Variance Variance has a central role in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling. Variance Variance is an important tool in the sciences, where statistical analysis of data is common [...More...]  "Variance" on: Wikipedia Yahoo
