Canal de communication (théorie de l'information)vignette En théorie de l'information, un canal de communication ou canal de transmission est un support (physique ou non) permettant la transmission d'une certaine quantité d'information, depuis une source (ou émetteur) vers un destinataire (ou récepteur). Souvent, le canal altère l'information transmise, par exemple en ajoutant un bruit aléatoire. La quantité d'information qu'un canal de communication peut transporter est limitée : on parle de capacité du canal.
Saison 2018 des Cardinals de Saint-LouisThe 2018 St. Louis Cardinals season was the 137th for the St. Louis Cardinals of Major League Baseball (MLB), a franchise in St. Louis, Missouri. It was the 127th season for the Cardinals in the National League (NL), and their 13th at Busch Stadium III. Forbes ranked the Cardinals as the seventh-highest valued team of the 30 teams in 2017 for its 1.9billionvaluation(+6319 million revenue, and $40 million operating income. The Cardinals also had baseball's second-highest local television rating, averaging 7.

Set-builder notationIn set theory and its applications to logic, mathematics, and computer science, set-builder notation is a mathematical notation for describing a set by enumerating its elements, or stating the properties that its members must satisfy. Defining sets by properties is also known as set comprehension, set abstraction or as defining a set's intension. Set (mathematics)#Roster notation A set can be described directly by enumerating all of its elements between curly brackets, as in the following two examples: is the set containing the four numbers 3, 7, 15, and 31, and nothing else.
Dragon Flower Church of the Heart-bound Heavenly WayThe Holy Dragon Flower Church of the Heart-bound Heavenly Way (一心天道龙华圣教会 Yīxīn tiāndào lónghuá shèng jiàohuì), also known simply as Yixin Tiandao (一心天道 "Heart-bound Heavenly Way"), Yizhendao (一真道 "Way of the One Truth") or the Holy Church of the One Truth (一真圣教会 Yīzhēn shèng jiàohuì), or Changmaodao (长毛道 "Way of the Long Hair"), is a Chinese folk religious sect part of the Xiantiandao tradition.

Cutting stock problemIn operations research, the cutting-stock problem is the problem of cutting standard-sized pieces of stock material, such as paper rolls or sheet metal, into pieces of specified sizes while minimizing material wasted. It is an optimization problem in mathematics that arises from applications in industry. In terms of computational complexity, the problem is an NP-hard problem reducible to the knapsack problem. The problem can be formulated as an integer linear programming problem.
Inequalities in information theoryInequalities are very important in the study of information theory. There are a number of different contexts in which these inequalities appear. Entropic vector Consider a tuple of finitely (or at most countably) supported random variables on the same probability space. There are 2n subsets, for which (joint) entropies can be computed. For example, when n = 2, we may consider the entropies and .

Robert KlippelRobert Klippel AO (19 June 1920 19 June 2001) was an Australian constructivist sculptor and teacher. He is often described in contemporary art literature as Australia's greatest sculptor. Throughout his career he produced some 1,300 pieces of sculpture and approximately 5,000 drawings. Klippel was born in Potts Point, Sydney on 19 June 1920. At the age of six, he made his first model ship after being taken on a ferry ride on Sydney Harbour. Model making became a passion. He was educated at Sydney Grammar School.
Ensemblevignette|Ensemble de polygones dans un diagramme d'Euler En mathématiques, un ensemble désigne intuitivement un rassemblement d’objets distincts (les éléments de l'ensemble), « une multitude qui peut être comprise comme une totalité » pour paraphraser Georg Cantor qui est à l'origine de la théorie des ensembles. Dans une approche axiomatique, la théorie des ensembles est une théorie de l'appartenance (un élément d'un ensemble est dit « appartenir » à cet ensemble).
