Multi-mode optical fiberMulti-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 100 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. The standard G.651.1 defines the most widely used forms of multi-mode optical fiber.
Mode de défaillanceLe mode de défaillance est la forme observable du dysfonctionnement d’un produit ou d’une opération du système étudié. Il sert de base de travail dans l'élaboration d'une analyse de type AMDEC Un mode de défaillance doit répondre aux caractéristiques suivantes : Il est relatif à la fonction étudiée. Il décrit la manière dont le système ne remplit plus sa fonction. Il s'exprime en termes techniques précis (court-circuit...) Il existe 5 modes génériques de défaillance : perte de la fonction fonctionnement in
Boat buildingBoat building is the design and construction of boats and their systems. This includes at a minimum a hull, with propulsion, mechanical, navigation, safety and other systems as a craft requires. Wood is the traditional boat building material used for hull and spar construction. It is buoyant, widely available and easily worked. It is a popular material for small boats (of e.g. length; such as dinghies and sailboats). Its abrasion resistance varies according to the hardness and density of the wood and it can deteriorate if fresh water or marine organisms are allowed to penetrate the wood.

HolotypeA holotype is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept.
