The Karnaugh map ( KM or K-map) is a method of simplifying Boolean algebra expressions. Maurice Karnaugh introduced it in 1953 [ 1][ 2] as a refinement of Edward W. Veitch 's 1952 Veitch chart, [ 3][ 4] which itself was a rediscovery of Allan Marquand 's 1881 logical diagram[ 5][ 6] aka Marquand diagram[ 4] but now with a focus set on its ...
Fibonacci sequence. In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes ...
Gregg shorthand is a system of phonography, or a phonemic writing system, which means it records the sounds of the speaker, not the English spelling. [ 4] For example, it uses the f stroke for the / f / sound in funnel, telephone, and laugh, [ 8] and omits all silent letters. [ 4] The system is written from left to right and the letters are joined.
n. th root. In mathematics, an nth root of a number x is a number r (the root) which, when raised to the power of the positive integer n, yields x: The integer n is called the index or degree, and the number x of which the root is taken is the radicand. A root of degree 2 is called a square root and a root of degree 3, a cube root.
5S (methodology) 5S ( Five S) is a workplace organization method that uses a list of five Japanese words: seiri (整理), seiton (整頓), seisō (清掃), seiketsu (清潔), and shitsuke (躾). These have been translated as 'sort', 'set in order', 'shine', 'standardize', and 'sustain'. [ 1] The list describes how to organize a work space for ...
The method successively extracts the smaller interruption cycles from a sequence, which models the material memory effect seen with stress-strain hysteresis cycles. [1] This simplification allows the number of cycles until failure of a component to be determined for each rainflow cycle using either Miner's rule to calculate the fatigue damage ...
Gauss–Seidel method. In numerical linear algebra, the Gauss–Seidel method, also known as the Liebmann method or the method of successive displacement, is an iterative method used to solve a system of linear equations. It is named after the German mathematicians Carl Friedrich Gauss and Philipp Ludwig von Seidel.
In numerical linear algebra, the tridiagonal matrix algorithm, also known as the Thomas algorithm (named after Llewellyn Thomas ), is a simplified form of Gaussian elimination that can be used to solve tridiagonal systems of equations. A tridiagonal system for n unknowns may be written as. where and . For such systems, the solution can be ...
