1Variable star designation — Variable stars are named using a variation on the Bayer designation format of an identifying label (as described below) combined with the Latin genitive of the name of the constellation in which the star lies. See List of constellations for a… …
2Variable star — A star is classified as variable if its apparent brightness as seen from Earth changes over time, whether the changes are due to variations in the star s actual luminosity, or to variations in the amount of the star s light that is blocked from… …
3Variable displacement — is an automobile engine technology that allows the engine displacement to change, usually by deactivating cylinders, for improved fuel economy. The technology is primarily used in large, multi cylinder engines. Many automobile manufacturers have… …
4Variable gauge axles — (VGA) are axles that allow railway vehicles to pass from tracks of one rail gauge to a different gauge. Variable gauge axles are used to allow the running of trains between Spain and France, Europe and Russia, Kazakhstan and China, and Mongolia… …
5Variable retention — is a relatively new silvicultural system that follows nature s model by always retaining a significant part of the forest after harvesting. Variable retention harvests serve to promote desired natural regeneration while preserving unique features …
6Variable length intake manifold — (VLIM) is an automobile engine manifold technology. As the name implies, VLIM can vary the length of the intake tract in order to optimize power and torque, as well as provide better fuel efficiency.There are two main effects of variable intake… …
7Variable valve actuation — Variable Valve Actuation, or VVA, is a generalised term used to describe any mechanism or method that can alter the shape or timing of a valve lift event within an internal combustion engine. There are many ways in which this can be achieved,… …
8Variable envelope return path — (VERP) is a technique used by some electronic mailing list software to enable automatic detection and removal of undeliverable e mail addresses. It works by using a different return path (also called envelope sender ) for each recipient of a… …
9System F — System F, also known as the polymorphic lambda calculus or the second order lambda calculus, is a typed lambda calculus. It was discovered independently by the logician Jean Yves Girard and the computer scientist John C. Reynolds. System F… …
10Variable-order Markov model — Variable order Markov (VOM) models are an important class of models that extend the well known Markov chain models. In contrast to the Markov chain models, where each random variable in a sequence with a Markov property depends on a fixed number… …
