Core (Stone Temple Pilots album)

Core is the debut album by American rock band Stone Temple Pilots, released on September 29, 1992 through Atlantic Records. The album, which peaked at #1 on the Billboard Heatseekers chart and #3 on the Billboard 200, was certified 8x platinum by the RIAA on December 18, 2001, making it the band's best-selling album.

Core (group theory)

In group theory, a branch of mathematics, a core is any of certain special normal subgroups of a group. The two most common types are the normal core of a subgroup and the p-core of a group.

Core (game theory)

In game theory, the core is the set of feasible allocations that cannot be improved upon by a subset (a coalition) of the economy's consumers. A coalition is said to improve upon or block a feasible allocation if the members of that coalition are better off under another feasible allocation that is identical to the first except that every member of the coalition has a different consumption bundle that is part of an aggregate consumption bundle that can be constructed from publicly available technology and the initial endowments of each consumer in the coalition.

An allocation is said to have the core property if there is no coalition that can improve upon it. The core is the set of all feasible allocations with the core property.

Core (radio station)

Core was a digital radio station broadcasting across the UK on the Digital One and streamed online. It was aimed at 16- to 24-year-olds with a focus on new music.

Core (novel)

Core is a science fiction novel by author Paul Preuss. First published in August 1993, it is about a group of scientists who must undertake a dangerous trip to the core of the Earth.

A 2003 film, The Core, was loosely based on this novel.

Core (anatomy)

In common parlance, the core of the body is broadly considered to be the torso. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck.

Core (Persefone album)

Core is an album by metal band Persefone. The album was released on 23 August 2006 by label Soundholic. Persefone re-released Core on April 18, 2014. Core was released worldwide through Vicisolum Records. The album included a 16-page booklet and a bonus track. Pere Revert was involved in the producing of the album (Shin-ken, Spiritual Migration).

Core (functional analysis)

In functional analysis, a discipline within mathematics, a core may be:

  • An essential domain of a closed operator; see Unbounded_operator#Closed_linear_operators; or
  • A radial kernel of a subset of a vector space; see Algebraic interior.

Core (graph theory)

In the mathematical field of graph theory, a core is a notion that describes behavior of a graph with respect to graph homomorphisms.

Core (band)

Core was a stoner rock band from New Jersey during the late 1990s.

Core (optical fiber)

The core of a conventional optical fiber is a cylinder of glass or plastic that runs along the fiber's length. The core is surrounded by a medium with a lower index of refraction, typically a cladding of a different glass, or plastic. Light travelling in the core reflects from the core-cladding boundary due to total internal reflection, as long as the angle between the light and the boundary is less than the critical angle. As a result, the fiber transmits all rays that enter the fiber with a sufficiently small angle to the fiber's axis. The limiting angle is called the acceptance angle, and the rays that are confined by the core/cladding boundary are called guided rays.

The core is characterized by its diameter or cross-sectional area. In most cases the core's cross-section should be circular, but the diameter is more rigorously defined as the average of the diameters of the smallest circle that can be circumscribed about the core-cladding boundary, and the largest circle that can be inscribed within the core-cladding boundary. This allows for deviations from circularity due to manufacturing variation.

Another commonly quoted statistic for core size is the mode field diameter. This is the diameter at which the intensity of light in the fiber falls to some specified fraction of maximum (usually . For single-mode fiber, the mode field diameter is larger than the physical diameter of the core, because the light penetrates slightly into the cladding as an evanescent wave.

The three most common core sizes are:

  • 9 µm diameter ( single-mode)
  • 50 µm diameter ( multi-mode)
  • 62.5 µm diameter (multi-mode)

Core (manufacturing)

A core is a device used in casting and molding processes to produce internal cavities and reentrant angles. The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in injection molding.

An intriguing example of the use of cores is in the casting of engine blocks. For example, one of the GM V-8 engines requires 5 dry-sand cores for every casting.

CORE (real estate)

CORE, sometimes referred to as the CORE Group, is a New York-based, full-service real estate brokerage firm.

Core (architecture)

In architecture, a core is a vertical space used for circulation and services. It may also be referred to as a circulation core or service core. A core may include staircases, elevators, electrical cables, water pipes and risers.

A core allows people to move between the floors of a building, and distributes services efficiently to the floors.
