Discover a single quadrupole GC-MS system that can exceed regulatory requirements and facilitate the simultaneous analysis of PAHs in water and soil samples.

This article proposes an optimization model for simultaneous estimation of an origin-destination (O-D) matrix and a travel-cost coefficient for congested networks in a logit-based stochastic user ...

Procedures for the computation of the Fisher exact test of 2X2 tables by means of the alignment and multiplication of appropriate binomial coefficients are reviewed and extended to larger tables.

This paper presents a new Jacobi-type method to calculate a simultaneous Schur decomposition (SSD) of several real-valued, nonsymmetric matrices by minimizing an appropriate cost function. Thereby, ...

We develop a family of parallel algorithms for the SpKAdd operation that adds a collection of k sparse matrices. SpKAdd is a much needed operation in many applications including distributed memory ...
