Efficient performance tuning of parallel programs is often hard. Optimization is often done when the program is written as a last effort to increase the performance. With sequential programs each (executed) code segment will affect the completion time. In the case of a parallel program executed on a multiprocessor this is not always true, due to(More)
The agent-based approach has proved useful to modeling phenomena of traditional social fields. Huge numbers of agents are involved in simulating social activities. The agents are heterogeneous and semi-organized to model the social activities. In order to apply agent based simulation results to practical usages, it is necessary to show potential users the(More)
Efficient performance tuning of parallel programs is often hard. Optimization is often done when the program is written as a last effort to increase the performance. With sequential programs each (executed) code segment will affect the total execution time of the program. Thus, any code segment that is optimized in a sequential program will decrease the(More)
In 1991, Denmark established a Patient Insurance Scheme, the fourth Nordic country to do so. Under the various national Nordic schemes, patients can receive indemnification for the consequences of medical injury even where the injury is not caused by negligent treatment. Instead emphasis is laid on whether the injury, viewed in retrospect, could have been(More)
The Capsule Reviews are intended to provide a short succinct review of each paper in the issue in order to bring the content to a wider readership. External intrusion is a serious threat to the security of a system connected to a network. There are two forms of external intrusions: weak and strong. Both forms involve the attacker exploiting a bug of a(More)
