This paper introduces and solves a security problem of pervasive computing: how to define authorizations for offline interactions when trust relationships among entities do not ex...
Chandy et al. proposed the methodology of “self-similar algorithms” for distributed computation in dynamic environments. We further characterize the class of functions computab...
This paper deals with convex relaxations for quadratic distance problems, a class of optimization problems relevant to several important topics in the analysis and synthesis of ro...
