Modeling of in situ Biorestoration of Organic Compounds in Groundwater
A convergent numerical method for modeling in situ biorestoration of contaminated groundwater is outlined. This method treats systems of transport-biodegradation equations by operator splitting in time. Transport is ...
Matroid Optimization and Algorithms
This paper reviews matroid optimization and algorithms including applications of matroid intersection; submodular functions and polymatroids; submodular flows and other general models; matroid connectivity algorithms; ...
The Plane-Wave Detection Problem
We study in some detail a simple nonlinear estimation problem, which shares several important features with some inverse problems in wave propagation. We consider the estimation of waveforms and incidence angles of transient ...
Implicit Application of Polynomial Filters in a k-Step Arnoldi Method
The Arnoldi process is a well known technique for approximating a few eigenvalues and corresponding eigenvectors of a general square matrix. Numerical difficulties such as loss of orthogonality and assessment of the numerical ...
On the Optimal Design of Columns Against Buckling
We establish existence, derive necessary conditions, and construct and test an algorithm for the maximization of a column's Euler buckling load under a variety of boundary conditions over a general class of admissible ...
