MaquetteUne maquette est une représentation partielle ou complète d'un système ou d'un objet (existant ou en projet) afin d'en tester et valider certains aspects et/ou le comportement (maquette fonctionnelle), ou simplement à des fins ludiques (maquette de jeu) ou informatives (présentation pédagogique ou commerciale d'une réalisation ou d'un projet). La maquette peut être réalisée en deux ou trois dimensions, à une échelle donnée, le plus souvent réduite ou agrandie pour en faciliter la visualisation ou la manipulation.
Wireless LANA wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. This gives users the ability to move around within the area and remain connected to the network. Through a gateway, a WLAN can also provide a connection to the wider Internet. Wireless LANs based on the IEEE 802.11 standards are the most widely used computer networks in the world.
Dye-sublimation printingDye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage. This understanding of the process was later shown to be incorrect, as there is some liquefication of the dye.
Cost–utility analysisCost–utility analysis (CUA) is a form of economic analysis used to guide procurement decisions. The most common and well-known application of this analysis is in pharmacoeconomics, especially health technology assessment (HTA). In health economics, the purpose of CUA is to estimate the ratio between the cost of a health-related intervention and the benefit it produces in terms of the number of years lived in full health by the beneficiaries. Hence it can be considered a special case of cost-effectiveness analysis, and the two terms are often used interchangeably.
Wireless ad hoc networkA wireless ad hoc network (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes. The determination of which nodes forward data is made dynamically on the basis of network connectivity and the routing algorithm in use.
Impression 3Dalt=Une grenouille en plastique bleue est en cours de construction par une imprimante 3D|vignette|Objet imprimé en 3D par une Ultimaker 2 Go vignette|Imprimante 3D dans un fab lab béninois.L'impression 3D ou fabrication additive regroupe les procédés de fabrication permettant de créer des pièces en volume par ajout de matière en couches successives. Elle s'oppose à la fabrication soustractive. Cette famille de procédés a commencé à se développer au début des années 1980 avec pour objectif principal de faciliter le prototypage rapide, puisque le coût de production est pratiquement indépendant de la quantité produite.
