Separation Logic with inductive definitions is a well-known approach for deductive verification of programs that manipulate dynamic data structures. Deciding verification conditions in this context is usually based on user-provided lemmas relating the inductive definitions. We propose a novel approach for generating these lemmas automatically which is based on simple syntactic criteria and dete...

We study a relativistic plasma containing charged chiral fermions in an external electric field. We show that with the presence of both vector and axial charge densities, the electric field can induce an axial current along its direction and thus cause chirality separation. We call it the chiral electric separation effect (CESE). On a very general basis, we argue that the strength of CESE is pr...

Videoconference systems have been around the market for a long time. Their aim is to provide a way of carrying out meetings without the need for having physical presence of the participants. However, the sense of realism achieved by these systems is usually far away from the one expected by the people involved in the communication. In this paper, we present several advances in audio signal proc...

In cutting plane methods, the question of how to generate the “best possible” set of cuts is both central and crucial. We propose a lexicographic multi-objective cutting plane generation scheme that generates, among all the maximally violated valid inequalities of a given family, an inequality that is undominated and maximally diverse w.r.t. the cuts that were previously found. By optimizing a ...

Polygeneration of hydrogen, heat, and power has been shown to improve overall plant efficiency by creating more products and introducing synergy which improve fuel cell performance (Figure 1). The integration of an absorption chiller with a high temperature fuel cell for polygeneration of combined cooling, heating, hydrogen, and power is studied. Steady-state and dynamic computer models are uti...
