Capteur photographiqueUn capteur photographique est un composant électronique photosensible servant à convertir un rayonnement électromagnétique (UV, visible ou IR) en un signal électrique analogique. Ce signal est ensuite amplifié, puis numérisé par un convertisseur analogique-numérique et enfin traité pour obtenir une . Le capteur est donc le composant de base des appareils photo et des caméras numériques, l'équivalent du film (ou pellicule) en photographie argentique.
Graphe de flot de contrôleEn informatique, un graphe de flot de contrôle (abrégé en GFC, control flow graph ou CFG en anglais) est une représentation sous forme de graphe de tous les chemins qui peuvent être suivis par un programme durant son exécution. Dans un GFC, les sommets du graphe représentent un bloc de base, c'est-à-dire un bout de code d'un seul tenant sans sauts ni cibles de sauts. Les cibles de sauts marquent le début d'un bloc de base, tandis que les sauts en marquent la fin. Les arcs représentent les sauts dans le flot de contrôle.
AnglingAngling (from Old English angol, meaning "hook") is a fishing technique that uses a fish hook attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining also exist. Modern angling rods are usually fitted with a fishing reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and traditional cane pole fishing are two rod-angling methods that do not use any reel.
Fishing baitFishing bait is any substance used to attract and catch fish, e.g. on a fishing hook. Bait items are both selected from and placed within the environment in order to capture prey. Traditionally, fishing bait is natural fish food such as night-crawlers, insects, worms, and smaller bait fish. Fishermen also use lures such as processed food, plastic baits and bionic lures to attract fish. Despite the importance of fish's attraction to bait, the way fish react to different baits is quite poorly understood.
Wild fisheriesA wild fishery is a natural body of water with a sizeable free-ranging fish or other aquatic animal (crustaceans and molluscs) population that can be harvested for its commercial value. Wild fisheries can be marine (saltwater) or lacustrine/riverine (freshwater), and rely heavily on the carrying capacity of the local aquatic ecosystem. Wild fisheries are sometimes called capture fisheries. The aquatic life they support is not artificially controlled in any meaningful way and needs to be "captured" or fished.
Pêche commercialeCommercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is also known as industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well.
