We consider the problem of verifying reachability properties of stochastic real-time systems modeled as generalized semi-Markov processes (GSMPs). The standard simulation-based tec...
There is a growing recognition of the need to apply formal mathematical methods in the design of \high con dence" computing systems. Such systems operate in safety critical co...
State Space Analysis is one of the most developed analysis methods for Petri Nets. The main problem of state space analysis is the size of the state spaces. Several ways to reduce ...
In off-line handwriting recognition, classifiers based on hidden Markov models (HMMs) have become very popular. However, while there exist well-established training algorithms, s...
We present a model of access control which provides fine-grained data-dependent control, can express permissions about permissions, can express delegation, and can describe syste...
