The peer-to-peer (P2P) based video streaming has emerged as a promising solution for Internet video distribution. Leveraging the resource available at end users, this approach poses great potential to scale in the Internet. We have now seen the commercial P2P streaming systems that are orders of magnitude larger than the earlier academic systems. We believe(More)
UNLABELLED Adolescence is a critical developmental phase during which risk-taking behaviors increase across a variety of species, raising the importance of understanding how brain changes contribute to such behaviors. While the prefrontal cortex is thought to influence adolescent risk taking, the specific ways in which it functions are unclear. Using(More)
Despite being one of the healthiest developmental periods, morbidity and mortality rates increase dramatically during adolescence, largely due to preventable, risky behaviors. Heightened reward sensitivity, coupled with ineffective cognitive control, has been proposed to underlie adolescents' risk taking. In this study, we test whether reward sensitivity(More)
In this paper, an approach that uses dynamic voltage scaling (DVS) to reduce the configuration energy of runtime reconfigurable devices is proposed. The basic idea is to use configuration prefetching and parallelism to create excessive system idle time and apply DVS on the configuration process when such idle time can be utilized. A genetic algorithm is(More)
Multitasking on reconfigurable logic can achieve very high silicon reusability. However, configuration latency is a major limitation and it can largely degrade the system performance. One reason is that tasks can run in parallel but configurations of the tasks can be done only in sequence. This work presents a novel configuration model to enable(More)
Reconfigurable system is a promising alternative to deliver both flexibility and performance at the same time. New reconfigurable technologies and technology-dependent tools have been developed, but a system-level design methodology to support system analysis and fast design space exploration is missing. In this paper, we present a SystemC-based(More)
