Displacement chromatography — is a chromatography technique in which a sample is placed onto the head of the column[n 1] and is then displaced by a solute that is more strongly sorbed than the components of the original mixture. The result is that the components are resolved… … Wikipedia
Matrix (mathematics) — Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… … Wikipedia
Direct stiffness method — As one of the methods of structural analysis, the direct stiffness method (DSM), also known as the displacement method or matrix stiffness method, is particularly suited for computer automated analysis of complex structures including the… … Wikipedia
Finite element method in structural mechanics — Finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by… … Wikipedia
