In core memory, small ring-shaped magnets - the cores - are threaded by two crossed wires, X and Y, to make a matrix known as a plane. When one X and one Y wire are powered, a magnetic field is generated at a 45-degree angle to the wires. The core magnets sit on the wires at a 45-degree angle, so the single core wrapped around the crossing ...
For this reason, later core systems combined the two into a single wire, and used circuitry in the memory controller to switch the function of the wire. However, when Sense wire crosses too many cores, the half select current can also induce a considerable voltage across the whole line due to the superposition of the voltage at each single core.
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. [1] It is a simple wire-frame, two dimensional drawing of a cube with no visual cues as to its orientation, so it can be interpreted to have either the lower-left or the upper-right square as its front side.
In computer science, cycle detection or cycle finding is the algorithmic problem of finding a cycle in a sequence of iterated function values.. For any function f that maps a finite set S to itself, and any initial value x 0 in S, the sequence of iterated function values
Square D is an American manufacturer of electrical equipment headquartered in Andover, Massachusetts. Square D is a flagship brand of Schneider Electric , which acquired the company in 1991. The company was listed on the New York Stock Exchange for 55 years prior to its acquisition without reporting financial loss in any calendar quarter ...
In psychology and cognitive neuroscience, pattern recognition is a cognitive process that matches information from a stimulus with information retrieved from memory. [1]Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory.
The codebreaker tries to guess the pattern, in both order and color, within eight to twelve turns. Each guess is made by placing a row of code pegs on the decoding board. [ 8 ] : 120 Once placed, the codemaker provides feedback by placing from zero to four key pegs in the small holes of the row with the guess.
He appeared in four of the five seasons (primarily seasons three and four) of the HBO program The Wire as Howard "Bunny" Colvin. [4] Wisdom had initially auditioned for the role of Stringer Bell. [5] He has also starred in the 2004 films Barbershop 2: Back in Business and Ray, and the 2007 film Freedom Writers.
