A coarse structure on a set is a collection of subsets of (therefore falling under the more general categorization of binary relations on ) called controlled set s, and so that possesses the identity relation, is closed under taking subsets, inverses, and finite unions, and is closed under composition of relations.
Typically, the coarse problem corresponds to a grid that is twice or three times coarser. Coarse spaces (coarse model, surrogate model) are the backbone of algorithms and methodologies exploiting the space mapping concept for solving computationally intensive engineering modeling and design problems.
All possible polar topologies on a dual pair are finer than the weak topology and coarser than the strong topology. The complex vector space C n may be equipped with either its usual (Euclidean) topology, or its Zariski topology. In the latter, a subset V of C n is closed if and only if it consists of all solutions to some system of polynomial ...
Kosher salt is a pure, coarse-grained, additive-free salt that doesn’t include any anti-caking agents or iodine; it is less salty than fine-grained table salt and the preferred option of most ...
The more gray, the coarser your new texture will be, which means the more adjustment you’ll have to styling it. It’s best to stick with a style that you already love,” he advises.
A partition α of a set X is a refinement of a partition ρ of X—and we say that α is finer than ρ and that ρ is coarser than α—if every element of α is a subset of some element of ρ. Informally, this means that α is a further fragmentation of ρ. In that case, it is written that α ≤ ρ.
More than 70% of sodium consumed ... kosher salt — traditionally used for koshering meat prepared according Jewish dietary laws— is coarser than table salt or sea salt. It’s mined, but not ...
Coarse sandpaper, a form of paper where an abrasive material has been fixed to its surface, allowing rapid removal of material by rubbing. Coarse structure , on a set X is a collection of subsets of the cartesian product X × X with certain. properties which allow the large-scale structure of metric spaces and topological spaces to be defined.
