Recently, a demand of adaptive multimedia service, which supports multimedia service migration according to user's location and characteristics of user device, is increased. In this paper, we propose a service migration system, which becomes aware of user device using intelligent agent. And we design and implement the ontology-based intelligent agent, which is aware of the context in its environment. Moreover, we implement a context reasoning system using location information.

Preplanned recovery using redundant trees in vertex-redundant or edge-redundant graphs is extended to the case where each edge has a cost and the goal is to find a pair of working and protection trees such that the cost of the working tree is as low as possible. We present efficient heuristic algorithms for this problem. Extensive computational results show that the cost of the working tree found with our algorithm is within 19% of the cost of a minimum spanning tree on the average, while the smaller cost of the working and protection trees found by the original algorithm without QoS consideration is about 95% over the cost of a minimum spanning tree on the average.

In this paper, we propose a space compression technique for digital circuits for minimizing the storage for the circuits under test while maintaining the fault coverage information. In this technique, a compaction tree is generated based on the circuit under test. The detectable error probability is calculated by using the Boolean Difference Method. The output modification is employed to minimize the number of faulty output data patterns which have the same compressed form as the fault-free patterns. The compressed outputs are then fed into a syndrome counter to derive the signature for the circuit. Simulations were performed on known combinational circuits and the results indicate that the loss in fault coverage caused by compression is in the range of 0-10% which is rather small.
