A Comparative Assessment of Model Predictive Current Control and Space Vector Modulation in a Direct Matrix Converter Matrix converters (MCs) are a very attractive alternative to conventional back-to-back converters with dc links. In this paper, a performance comparison be... Rivera, M,Wilson, A...
T Tanaka,A Masuda 摘要: Rare-earth elements in a whole-rock sample and in major components of the Allende meteorite were investigated; for a few samples, abundances of Ba, Sr, Ca, and Al were also determined. Of the materials investigated in the present work, Ca Al-rich inclusions G ...
737. Find Elements in Matrix Given a matrix, find a element that appear in all the rows in the matrix.You can assume that there is only one such element. 样例 Forexample:Givena matrix:[[2,5,3],[3,2,1],[1,3,5]]return3 哈希表查找 这个倒不是一定得用哈希表,只是用哈希好写一些,...
A method of manufacturing an integrated circuit provides a metrology mark (e.g., alignment mark or overlay mark). The method includes forming a first plurality of first structures arranged in a matrix in a substrate. Portions of the matrix are covered with a mask such that first portions of...
Matrix elements of the type <M||scrO||M¯ > are evaluated using a relativized quark model for the K, D, B, and Bsystems where scrO=[q¯γ(1-γ)q][q¯γ (1-γ)q], scrO=[q¯(1-γ)q] [q¯(1 +γ)q], scrO=[q¯γ(1-γ)q][q¯γ (1+γ)q], and scrO=...

Some numerical simulations are presented to assess the efficiency of the proposed method and the synthesis performance comparisons with matrix pencil method and genetic algorithm are also performed to demonstrate the superiority of the proposed algorithm over traditional algorithm in this literature. 展开 ...
Get a matrix with indicating the elements that were missing in the input data. Convenient for estimating imputation performance.Henning Redestig
The use of matrix modifiers could represent a toxicological risk to the operators. Critical factors should be considered ('metal sheets') for each element in each matrix. For instance 27 factors for Cr in serum have been suggested. 展开 ...
By using the j-j coupling model, all the _-decay nuclear matrix elements are calculated (in terms of radial integrals) for one- and two-nucleon configurations. The operators in terms of which one can describe the entire theory are of five types. Three of these, involving the nucleon moment...
