Enterprises require mechanisms to ensure that their business processes implement and fulfill internal controls in context of regulatory compliance such as Sarbanes Oxley Act. In th...
We present a Prolog program that implements a sound and complete theorem prover for first-order intuitionistic logic. It is based on free-variable semantic tableaux extended by an...
This paper presents an algorithm that achieves hyper-arc consistency for the soft alldifferent constraint. To this end, we prove and exploit the equivalence with a minimum-cost flo...
We describe a mechanism that can be used to drive interfaces from a description logic (DL) model of the domain. A simple layer with limited expressivity sits on top of the DL, wit...
Anonymity means that the identity of the user performing a certain action is maintained secret. The protocols for ensuring anonymity often use random mechanisms which can be descr...
