Fiber-optic cableA fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for optical communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building.
Processus de Poissonvignette|Schéma expliquant le processus de Poisson Un processus de Poisson, nommé d'après le mathématicien français Siméon Denis Poisson et la loi du même nom, est un processus de comptage classique dont l'équivalent discret est la somme d'un processus de Bernoulli. C'est le plus simple et le plus utilisé des processus modélisant une . C'est un processus de Markov, et même le plus simple des processus de naissance et de mort (ici un processus de naissance pur).
Active-pixel sensorAn active-pixel sensor (APS) is an , which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor.
Processus stochastiqueUn processus ou processus aléatoire (voir Calcul stochastique) ou fonction aléatoire (voir Probabilité) représente une évolution, discrète ou à temps continu, d'une variable aléatoire. Celle-ci intervient dans le calcul classique des probabilités, où elle mesure chaque résultat possible (ou réalisation) d'une épreuve. Cette notion se généralise à plusieurs dimensions. Un cas particulier important, le champ aléatoire de Markov, est utilisé en analyse spatiale.
Business process modelingBusiness process modeling (BPM) in business process management and systems engineering is the activity of representing processes of an enterprise, so that the current business processes may be analyzed, improved, and automated. BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter experts, who have specialized knowledge of the processes being modeled; or more commonly by a team comprising both. Alternatively, the process model can be derived directly from events' logs using process mining tools.
