Depending on the threat perception to the person, the category is divided into six tiers: SPG, Z+ (highest level), Z, Y+, Y and X. IndividualsKingdom, prisoners are divided into four categories of security. Every adult in prison is assigned a different category, all depending on the crime they committedbe rated as a Category 2 hurricane, if it has winds of between 83 and 95 kn (96–110 mph, 154–177 km/h). When a system becomes a Category 3 hurricane withIn mathematics, a complete category is a category in which all small limits exist. That is, a category C is complete if every diagram F : J → C (whereIn mathematics, a comma category (a special case being a slice category) is a construction in category theory. It provides another way of looking at morphisms:IUCN protected area categories, or IUCN protected area management categories, are categories used to classify protected areas in a system developed byA category killer is a retailer, often a big-box store, that specializes in and carries a deep product assortment within a given category and throughusing Category 1 cable/connectors Class B: link/channel up to 1 MHz using Category 2 cable/connectors Class C: link/channel up to 16 MHz using Category 3specifically category theory, a quasi-category (also called quasicategory, weak Kan complex, inner Kan complex, infinity category, ∞-category, Boardman complexIn electrical engineering utilization categories are defined by IEC standards and indicate the type of electrical load and duty cycle of the loads to easea category (German: Categorie in the original or Kategorie in modern German) is a pure concept of the understanding (Verstand). A Kantian category isA Category 5 Atlantic hurricane is a tropical cyclone that reaches Category 5 intensity on the Saffir–Simpson hurricane wind scale, within the AtlanticThis is a list of the longest-running television shows by category. The criterion for being the longest-running show is by the number of years the showIn mathematics, particularly in homotopy theory, a model category is a category with distinguished classes of morphisms ('arrows') called 'weak equivalences'In mathematics, a triangulated category is a category with the additional structure of a "translation functor" and a class of "exact triangles". ProminentCategory 2 or Category II may refer to: Category 2 cable, a grade of unshielded twisted pair cabling Category 2 tropical cyclone, on any of the TropicalIn category theory, a branch of mathematics, a closed category is a special kind of category. In a locally small category, the external hom (x, y) mapsA syntactic category is a syntactic unit that theories of syntax assume. Word classes, largely corresponding to traditional parts of speech (e.g. nounIn the mathematical field of category theory, the category of sets, denoted as Set, is the category whose objects are sets. The arrows or morphisms betweenThe Categories (Greek Κατηγορίαι Katēgoriai; Latin Categoriae or Praedicamenta) is a text from Aristotle's Organon that enumerates all the possible kindsCategory A services were a class of Canadian specialty television channel which, as defined by the Canadian Radio-television and Telecommunications Commissionwell-behaved type of morphism. A normal category is a category in which every monomorphism is normal. A conormal category is one in which every epimorphismIn category theory, a branch of mathematics, a dagger category (also called involutive category or category with involution) is a category equipped withmathematics, specifically in category theory, an additive category is a preadditive category C admitting all finitary biproducts. A category C is preadditive ifIn mathematics, an abelian category is a category in which morphisms and objects can be added and in which kernels and cokernels exist and have desirableIn mathematics, higher category theory is the part of category theory at a higher order, which means that some equalities are replaced by explicit arrowsAn aircraft approach category is a grouping which differentiates aircraft based on the speed at which the aircraft approaches a runway for a landing.
