Closed captioning (CC) and subtitling are both processes of displaying text on a television, video screen, or other visual display to provide additional or interpretive information.Both are typically used as a transcription of the audio portion of a program as it occurs (either verbatim or in edited form), sometimes including descriptions of non-speech elements.

In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] in terms of two positive parameters, denoted by alpha (α) and beta (β), that appear as exponents of the random variable and control the shape of the distribution.. The beta distribution has been applied to model the behavior of random …

Beta, named after the second letter of the Greek alphabet, is the software development phase following alpha.Software in the beta stage is also known as beta ware. A beta phase generally begins when the software is feature complete but likely to contain several known or unknown bugs. Software in the beta phase will generally have many more bugs in it than completed …

In probability theory and statistics, the beta-binomial distribution is a family of discrete probability distributions on a finite support of non-negative integers arising when the probability of success in each of a fixed or known number of Bernoulli trials is either unknown or random. The beta-binomial distribution is the binomial distribution in which the probability of success at …

History Founding. The method of least squares grew out of the fields of astronomy and geodesy, as scientists and mathematicians sought to provide solutions to the challenges of navigating the Earth's oceans during the Age of Discovery.The accurate description of the behavior of celestial bodies was the key to enabling ships to sail in open seas, where sailors could no longer rely on …

Formal theory. Formally, a string is a finite, ordered sequence of characters such as letters, digits or spaces. The empty string is the special case where the sequence has length zero, so there are no symbols in the string.

Beta Theta Pi (ΒΘΠ), commonly known as Beta, is a North American social fraternity that was founded in 1839 at Miami University in Oxford, Ohio.One of North America's oldest fraternities, as of 2022 it consists of 144 active chapters in the United States and Canada. More than 219,000 members have been initiated worldwide and there are currently around 8,500 undergraduate …

β-lactam antibiotics (beta-lactam antibiotics) are antibiotics that contain a beta-lactam ring in their chemical structure. This includes penicillin derivatives (), cephalosporins and cephamycins (), monobactams, carbapenems and carbacephems. Most β-lactam antibiotics work by inhibiting cell wall biosynthesis in the bacterial organism and are the most widely used group of antibiotics.

Linux (/ ˈ l iː n ʊ k s / LEE-nuuks or / ˈ l ɪ n ʊ k s / LIN-uuks) is an open-source Unix-like operating system based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution.. Distributions include the Linux kernel and supporting system software and libraries, many of which are provided ...

Linear least squares (LLS) is the least squares approximation of linear functions to data. It is a set of formulations for solving statistical problems involved in linear regression, including variants for ordinary (unweighted), weighted, and generalized (correlated) residuals. Numerical methods for linear least squares include inverting the matrix of the normal equations and orthogonal ...
