Additive Distances and Quasi-Distances Between Words
: We study additive distances and quasi-distances between words. We show that every additive distance is finite. We then prove that every additive quasi-distance is regularity-pres...

Rate-independent phase transitions in elastic materials: A Young-measure approach
A quasistatic evolution problem for a phase transition model with nonconvex energy density is considered in terms of Young measures. We focus on the particular case of a finite num...

Evaluation of the distance spectrum of variable-length finite-state codes
The class of variable-length finite-state joint source-channel codes is defined and a polynomial complexity algorithm for the evaluation of their distance spectrum presented. Issu...

On integer values of Kloosterman sums
Abstract. In this note we use Carlitz's lifting formula for Kloosterman sums and some results from the theory of cyclotomic fields to show that a Kloosterman sum over a finite...

Self-deployment of mobile sensors on a ring
Mobile sensors can self-deploy in a purely decentralized and distributed fashion, so to reach in finite time a state of static equilibrium in which they cover uniformly the enviro...
