Mesh Redistribution Strategies and Finite Element Schemes for Hyperbolic Conservation Laws
In this work we consider a new class of Relaxation Finite Element schemes for Conservation Laws, with more stable behavior on the limit area of the relaxation parameter. Combine t...

Sofic and Almost of Finite Type Tree-Shifts
We introduce the notion of sofic tree-shifts which corresponds to symbolic dynamical systems of infinite trees accepted by finite tree automata. We show that, contrary to shifts of...

On Preservation under Homomorphisms and Unions of Conjunctive Queries
Unions of conjunctive queries, also known as select-project-join-union queries, are the most frequently asked queries in relational database systems. These queries are definable b...

Staggered Finite Difference Schemes for Conservation Laws
In this work, we introduce new finite-difference shock-capturing central schemes on staggered grids. Staggered schemes may have better resolution of the corresponding unstaggered ...

Adaptive Finite Element Methods for Fluorescence Enhanced Frequency Domain Optical Tomography: Forward Imaging Problem
In this contribution we introduce adaptive finite element methods for forward modeling in fluorescence optical tomography. Adaptive local mesh refinement increases the accuracy of...
