Emerging models for context-aware role-based access control pose challenging requirements over policy administration. In this paper we address the issues raised by the decentraliz...

The specification of a simulation model of a complex traffic intersection using the Hierarchical Modeling And Simulation System-Java (HiMASS-j) is presented.
A novel method of hierarchical implicit modeling is presented, in which an implicit object is modeled by using a hierarchy of implicit surfaces. The hierarchy provides both layere...
Abstract: We introduce the input-output automaton, a simple but powerful model of computation in asynchronous distributed networks. With this model we are able to construct modular...
The dynamic texture (DT) is a probabilistic generative model, defined over space and time, that represents a video as the output of a linear dynamical system (LDS). The DT model ...
