We study the model-checking problem for weighted timed automata and the weighted CTL logic by the bisimulation approach. Weighted timed automata are timed automata extended with co...
We introduce ctm, a process calculus which embodies a notion of trust for global computing systems. In ctm each principal (location) is equipped with a policy, which determines its...
Communication structure is a way of improving the effectiveness of group communications by coordinating group members’ individual efforts. This study investigates the use of Del...
High dimensional data visualization is critical to data analysts since it gives a direct view of original data. We present a method to visualize large amount of high dimensional d...
Among the advantages of visual dataflow programming is that it can give the user a sense of location for the data in a computation. This can help novices build a mental picture of...
