Models and conceptualizations are necessary to understand and design ubiquitous systems that are context–aware not just from a technological point of view. The current technologi...
The Distributed Object Group Framework(DOGF) we constructed supports the grouping of distributed objects that are required for distributed application. From the DOGF, we manage dis...
Textbooks tell us that a birthday attack on a hash function h with range size r requires r1/2 trials (hash computations) to find a collision. But this is quite misleading, being t...
This paper shows a method to verifying the thermal status of complex FPGA-based circuits like microprocessors. Thus, the designer can evaluate if a particular block is working bey...
Services are usually developed and deployed independently; and systems can be formed by composing relevant services to achieve set goals. In such an open and dynamic environment, s...
