It is a software package developed by Department of Computer Science, University of Minnesota, United States, for partitioning unstructured meshes, large irregular graphs, and computing fill-reducing orderings of sparse matrices. It provides two programs partnmesh and partdmesh for partitioning meshes ...
Synonyms Functional decomposition ; Grid partitioning Definition Domain decomposition, in the context of parallel computing, refers to partitioning of computational work among multiple processors by distributing the computational domain of a problem, in other words, data associated with the problem. In the...
Domain decomposition methods in computer science refer to the technique of dividing a major grid into smaller subdomains, followed by further division into minor grids. This method is utilized in parallel computing to optimize load balancing, minimize communication costs, and prevent convergence issues ...
So it seems to me that someone needs to plan on recording all the Presidential (and vice-presidential) debates with a nice array of infrared, high speed, and high-definition cameras. And they need to do it in a public fashion so that every one of these candidates is very aware of it ...
In this paper,a multiplicity-preserving triangular set decomposition algorithm is proposed for a system of two polynomials,which involves only computing th... JS Cheng,XS Gao,Key Laboratory of Mathematics Mechanization,... - 《Journal of Systems Science & Complexity》 被引量: 6发表: 2014年 ...
assumed a convex domain when computing helmholtz’s decomposition. the generalization to non-convex domains involves additional treatment [ 51 ]. as non-convex domains occur in real-world applications (e.g. fans, cavities, and duct systems), schoder et al. [ 31 , 35 ] address them by the...
We propose a fast algorithm for the computing approximate GCD of univariate polynomials with coefficients that are given only to a finite accuracy. The alg... L Zhi 被引量: 73发表: 2003年 A continuum mechanical-based formulation of the variational sensitivity analysis in structural optimization. ...

In Wavelet Analysis and Its Applications, 1998 2.2.2.6 Polyphase representation Definition 2.2.2.6 Given a multidimensional sequence x(n) and a nonsingular matrixR, then its Type-I multidimensional polyphase components are defined as xa(n) = x(Rn + a), wheren∈ ℕ and a∈ (R). Now, ...
2Preliminaries and problem definition Throughout the paper we will useX, a matrix of sizen×m, as our input data. We will writeX⋅iandXi⋅to indicate theith column and row, respectively. We will write‖X‖F2=∑ijXij2to indicate the (squared) Frobenius norm. ...
