Problem structuring methodsProblem structuring methods (PSMs) are a group of techniques used to model or to map the nature or structure of a situation or state of affairs that some people want to change. PSMs are usually used by a group of people in collaboration (rather than by a solitary individual) to create a consensus about, or at least to facilitate negotiations about, what needs to change. Some widely adopted PSMs include soft systems methodology, the strategic choice approach, and strategic options development and analysis (SODA).
Mixing (mathematics)In mathematics, mixing is an abstract concept originating from physics: the attempt to describe the irreversible thermodynamic process of mixing in the everyday world: e.g. mixing paint, mixing drinks, industrial mixing. The concept appears in ergodic theory—the study of stochastic processes and measure-preserving dynamical systems. Several different definitions for mixing exist, including strong mixing, weak mixing and topological mixing, with the last not requiring a measure to be defined.
UnivariateIn mathematics, a univariate object is an expression, equation, function or polynomial involving only one variable. Objects involving more than one variable are multivariate. In some cases the distinction between the univariate and multivariate cases is fundamental; for example, the fundamental theorem of algebra and Euclid's algorithm for polynomials are fundamental properties of univariate polynomials that cannot be generalized to multivariate polynomials.
Association for Computing MachineryL'ACM (en anglais « Association for Computing Machinery », littéralement « association pour les machines de calcul ») est une association internationale à but non lucratif fondée en 1947, la première à être vouée à l'informatique. Sa mission consiste à développer et soutenir la recherche scientifique et l'innovation informatique. Elle siège dans la ville de New York aux États-Unis. La structure organisationnelle de l'ACM se décline en trois catégories d'antennes : thématiques, professionnelles et étudiantes.
