Slope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of slopes of soil- and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock. It is performed to assess the safe design of a human-made or natural slopes (e.g. embankments, road cuts, open-pit mining ...
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.
An important example of a log-concave density is a function constant inside a given convex body and vanishing outside; it corresponds to the uniform distribution on the convex body, which explains the term "central limit theorem for convex bodies". Another example: f(x 1, ..., x n) = const · exp(−(| x 1 | α + ⋯ + | x n | α) β) where α ...
v. t. e. In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes. Given a discrete random variable , which takes values in the set and is distributed according to , the entropy is where denotes the sum over the variable's possible ...
Detection limit. The limit of detection ( LOD or LoD) is the lowest signal, or the lowest corresponding quantity to be determined (or extracted) from the signal, that can be observed with a sufficient degree of confidence or statistical significance. However, the exact threshold (level of decision) used to decide when a signal significantly ...
In mathematics, a limit is the value that a function (or sequence) approaches as the argument (or index) approaches some value. [ 1] Limits of functions are essential to calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals . The concept of a limit of a sequence is further generalized to the concept ...
Asymptotic analysis. In mathematical analysis, asymptotic analysis, also known as asymptotics, is a method of describing limiting behavior. As an illustration, suppose that we are interested in the properties of a function f (n) as n becomes very large. If f(n) = n2 + 3n, then as n becomes very large, the term 3n becomes insignificant compared ...
This eigenvalue problem is called the Hermite equation, although the term is also used for the closely related equation ″ ′ =. whose solution is uniquely given in terms of physicist's Hermite polynomials in the form () = (), where denotes a constant, after imposing the boundary condition that u should be polynomially bounded at infinity.
