Abstract. We extend discrete-timed Petri nets with a cost model that assigns token storage costs to places and firing costs to transitions, and study the minimal cost reachability...
ÐReal-time middleware services must guarantee predictable performance under specified load and failure conditions, and ensure graceful degradation when these conditions are violat...
The ability to model the evolution of software technology trends is valuable to many stakeholders in industry, academia, and government. Yet we often depend exclusively on the opi...
A prototype Basic LOTOS interpreter, augmented for modelling real-time systems, is described. Primitive actions are treated as time-consuming, with separate start and end points, ...
We propose an HMM model for contour detection based on multiple visual cues in spatial domain and improve it by joint probabilistic matching to reduce background clutter. It is fu...
