M Lavrauw - 《Innovations in Incidence Geometry Algebraic Topological & Combinatorial》 被引量: 21发表: 2005年 Parallel Computation of AX and aTX This paper describes how to carry out the matrix-vector multiplications Ax and ATx on parallel computers where A is a sparse matrix arising from the...
sparse matrixTriplet-list is a frequently used storage structure for sparse matrix, and the addition of sparse matrix is also a frequently used operation. This paper enumerates three kinds of algorithm to implement the addition of sparse matrix. Moreover, it also compares and analyzes the ...
Evidence from high-resolution transmission electron microscopy demonstrated that the rod- or plate-like structures have simple cubic structures, whereas the spherical α-dispersoids are coherent with the Al matrix along the [101] zone axis of Al, resulting in finer dispersoids, higher thermal ...
count of WBCs in the body. Initial attempts were made by Aldred S. Warthin in 1906 [12], who suggested the use of a diluent that preserved the blood cells. A manual count of the cells was then performed to determine the ratio of cells and their counts. Presently, there are two ...
The large-scale matrix's numerical calculus is one of the hot spots in the parallel numerical operation domain, the traditional methods to realize large-scale matrix numerical operation is generally established the following thought: dividing the large-scale matrix into some sub-blocks. Large-scale ...
The most common Zn alloy systems consist of Zn-Mg-, Zn-Li-, Zn-Mn-, Zn-Ag-, and Zn-Cu-based alloys [3]. Due to the microgalvanic corrosion between the intermetallic phase and the matrix, the strengthening effect of the multiphase Zn alloy usually comes at the expense of the ...
However, Co-Cr-Mo-W bears higher melting temperature (about 1400 ◦C) than that of 316L, which results in holes in the surface because of the lower energy input that leaves residual unmelted Co-Cr-Mo-W powder in the matrix and thus leads to a poor surface bonding of 316L + 10Co-...
