The idea of the triangle was proposed by John Kenneth Galbraith and developed by Sábato as a model of policy-making in science and technology. [1]: 302–303 The model is based on the concept that in order for a scientific-technological system to exist in practice it is necessary for three sectors to be strongly linked together over the long term: the State (which formulates and implements ...
The initial derivation begins with vector addition to determine the orbiting body's position vector. Then based on the conservation of angular momentum and Keplerian orbit principles (which states that an orbit lies in a two dimensional plane in three dimensional space), a linear combination of said position vectors is established.
The matrix–vector multiplication can be done in () arithmetical operations where is the average number of nonzero elements in a row. The total complexity is thus O ( d m n ) {\displaystyle O(dmn)} , or O ( d n 2 ) {\displaystyle O(dn^{2})} if m = n {\displaystyle m=n} ; the Lanczos algorithm can be very fast for sparse matrices.
The Method (Spanish: El método) is a 2005 thriller film directed by Marcelo Piñeyro and based on the 2003 play El mètode Grönholm by Jordi Galceran.. It stars Eduardo Noriega, Najwa Nimri, Eduard Fernández, Pablo Echarri, Ernesto Alterio, Natalia Verbeke, Adriana Ozores and Carmelo Gómez, as the only eight actors in the film.
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

In probability theory, the first-order second-moment (FOSM) method, also referenced as mean value first-order second-moment (MVFOSM) method, is a probabilistic method to determine the stochastic moments of a function with random input variables.
The bond valence is a vector directed along the bond since it represents the electrostatic field linking the ions. If the atom is unconstrained, the sum of the bond valence vectors around an atom is expected to be zero, a condition that limits the range of possible bond angles.
The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is a multi-criteria decision analysis method, which was originally developed by Ching-Lai Hwang and Yoon in 1981 [1] with further developments by Yoon in 1987, [2] and Hwang, Lai and Liu in 1993. [3]
