to the correct marginals. However, on the QMR network, the loopy be liefs oscillated and had no obvious relation ship to the correct posteriors. We present some initial investigations into the cause of these oscillations, and show that some sim ple methods of preventing them lead to the wrong results

A serendipitous event is a fortunate by-product of some other activity. Therefore, serendipitous crime prevention occurs when actions that are primarily directed towards one area of crime prevention result in reductions in other areas of crime. This was the case with the problems of vandalism of

Most operating systems use interface interrupts to schedule network tasks. Interrupt-driven systems can provide low overhead and good latency at low of-fered load, but degrade significantly at higher arrival rates unless care is taken to prevent several pathologies. These are various forms

system. They delivered the working product on budget and close to schedule and, therefore, claimed a complete success. However, research showed the users had a very negative attitude, blaming the system for an increased workload and for causing widespread disruption because of its perceived failures. A

There has been considerable interest in understanding what may have led to Uganda’s dramatic decline in HIV prevalence, one of the world’s earliest and most compelling AIDS prevention successes. Survey and other data suggest that a decline in multi-partner sexual behavior is the behavioral change

The recent advances in MEMS, embedded systems and wireless communication technologies are making the realization and deployment of networked wireless microsensors a tangible task. Vital to the success of wireless microsensor networks is the ability of microsensors to "collectively perform

Abstract: The fitting of security devices to motor vehicles has become an important approach to the prevention of motor vehicle crime. In cars, manu-facturers have focused primarily on improving perimeter security to prevent breaking-in to the vehicle, and installing devices to prevent parked

. This leaves the door open for other attacks that use more sophisticated methods to mask their traffic. We propose an architecture called Secure Overlay Services (SOS) that proactively prevents DoS attacks, geared toward supporting Emergency Services or similar types of communication. The architecture

is prevented. We evaluate our design through trace driven simulation by comparing it with a pure data cache approach under three different memory ac-cess models. Our experiments show that this scheme is very effective for reducing the data access penalty for scientific programs and that is has moderate success
