Tensor decomposition and homotopy continuation [PDF]
, 2016 A computationally challenging classical elimination theory problem is to compute polynomials which vanish on the set of tensors of a given rank. By moving away from computing polynomials via elimination theory to computing pseudowitness sets via ...

Finite Element Methods with Artificial Diffusion for Hamilton-Jacobi-Bellman Equations [PDF]
, 2012 In this short note we investigate the numerical performance of the method of artificial diffusion for second-order fully nonlinear Hamilton-Jacobi-Bellman equations. The method was proposed in (M. Jensen and I. Smears, arxiv:1111.5423); where a framework

A discontinuous Galerkin moving mesh method for Hamilton-Jacobi equations [PDF]
, 2007 In this paper we consider the numerical solution of first-order Hamilton-Jacobi equations using the combination of a discontinuous Galerkin finite element method and an adaptive $r$-refinement (mesh movement) strategy.

Numerical methods for Stochastic differential equations: two examples
ESAIM: Proceedings and Surveys, 2018 The goal of this paper is to present a series of recent contributions arising in numerical probability. First we present a contribution to a recently introduced problem: stochastic differential equations with constraints in law, investigated through ...

Continuum Field Model of Street Canyon: Numerical Examples. Part 2
Engineering Transactions, 2015 Continuum field control model of a street canyon is considered. The six separate monocriterial optimal control problems consist of minimization of functionals of the total travel time, of global emissions of pollutants, and of global concentrations of ...

Conditioning moments of singular measures for entropy maximization II: Numerical examples
, 2015 If moments of singular measures are passed as inputs to the entropy maximization procedure, the optimization algorithm might not terminate. The framework developed in our previous paper demonstrated how input moments of measures, on a broad range of ...

Clustering solver for displacement-based numerical homogenization
Theoretical and Applied Mechanics Letters, 2022 Based on strain-clustering via k-means, we decompose computational domain into clusters of possibly disjoint cells. Assuming cells in each cluster take the same strain, we reconstruct displacement field.

On numerical methods for highly oscillatory problems in circuit simulation [PDF]
, 2009 We propose in this paper a novel technique for an efficient numerical approximation of systems of highly oscillatory ordinary differential equations. In particular, we consider electronic systems subject to modulated signals.
