Financial Core (also known as FiCore or Fi-Core) refers to a legal carve out that permits workers opposed to participating in a labor union to be employed under the benefits of a union's contracts without compelling them to be a member of that union.
ferrite core memory         
  • Diagram of a 4×4 plane of magnetic core memory in an X/Y line coincident-current setup. X and Y are drive lines, S is sense, Z is inhibit. Arrows indicate the direction of current for writing.
  • A 10.8×10.8 cm plane of magnetic core memory with 64 x 64 bits (4 Kb), as used in a [[CDC 6600]]. Inset shows ''word line'' architecture with two wires per bit
  • Close-up of a core plane. The distance between the rings is roughly 1 mm (0.04 in). The green horizontal wires are X; the Y wires are dull brown and vertical, toward the back. The sense wires are diagonal, colored orange, and the inhibit wires are vertical twisted pairs.
  • One of three inter-connected modules that make up an Omnibus-based PDP-8 core memory plane.  This is the middle of the three and contains the array of actual ferrite cores.
  • One of three inter-connected modules that make up an Omnibus-based (PDP 8/e/f/m) PDP-8 core memory plane.
  • One of three inter-connected modules that make up an Omnibus-based PDP-8 core memory plane.
  • [[Project Whirlwind]] core memory
  • Diagram of the [[hysteresis]] curve for a magnetic memory core during a read operation. Sense line current pulse is high ("1") or low ("0") depending on original magnetization state of the core.

<storage> (Or "core") An early form of non-volatile storage built (by hand) from tiny rings of magnetisable material threaded onto very fine wire to form large (e.g. 13"x13" or more) rectangluar arrays. Each core stored one bit of data. These were sandwiched between printed circuit boards(?). Sets of wires ran horizontally and vertically and where a vertical and horizontal wire crossed, a core had both wires threaded through it. A single core could be selected and magnetised by passing sufficient current through its horizontal and vertical wires. A core would retain its magnetisation until it was re-magnetised. The two possible polarities of magnetisation were used to represent the binary values zero and one. A third "sense" wire, passed through the core and, if the magnetisation of the core was changed, a small pulse would be induced in the sense wire which could be detected and used to deduce the core's original state. Some core memory was immersed in a bath of heated oil to improve its performance. Core memory was rendered obsolete by semiconductor memory. For example, the 1970s-era NCR 499 had two boards, each with 16 kilobytes of core memory. (1996-03-04)

Prepared-core technique

The prepared-core technique is a means of producing stone tools by first preparing common stone cores into shapes that lend themselves to knapping off flakes that closely resemble the desired tool and require only minor touch-ups to be usable.

In contrast to the production of core tools like handaxes, where cores themselves were the end product shaped and trimmed down by removal of flakes, in prepared-core technique large flakes are the product and the core is used to produce them. This shift made it faster and more resource-efficient, as multiple tools could be struck from a single piece of starting material.

Prepared core preparation techniques are grouped under the label Mode 3 technology. The best-known prepared core reduction method is the Levallois technique

Prepared core technology was likely invented independently multiple times at different locations. The regular use of Prepared core technology is associated with large-brained hominins such as Homo heidelbergensis, Neanderthals and modern humans. Its widespread use is the defining characteristic of the Middle Stone Age period in Africa and the Middle Palaeolithic (~300.000 - 40.000 years ago) in Europe.
