We develop a general, non-probabilistic model of prediction which is suitable for assessing the (un)predictability of individual physical events. We use this model to provide, for...

Abstract. Mobile devices are in roles where the integrity and confidentiality of their apps and data are of paramount importance. They usually contain a System-on-Chip (SoC), whic...
Abstract. Answer Set Programming is a widely known knowledge representation framework based on the logic programming paradigm that has been extensively studied in the past decades....
Specific preference statements may reverse general preference statements, thus constituting a change of attitude in particular situations. We define a semantics of preference re...
Abstract. In 1987 Ernst-R¨udiger Olderog provided an operational Petri net semantics for a subset of CCSP, the union of Milner’s CCS and Hoare’s CSP. It assigns to each proces...
Abstract. We revisit non-monotonic description logics based on circumscription (with preferences) and prove several decidability results for their satisfiability problem. In parti...

Abstract. While groups are generally helpful for the definition of authorization policies, their use in distributed systems is not straightforward. This paper describes a design f...
Vacuity checking is traditionally performed after model checking has terminated successfully. It ensures that all the elements of the specification have played a role in its satis...
Abstract. We consider the problem of verifying whether one action theory can simulate a second one. Action theories provide modular descriptions of state machines, and simulation m...
