Despite many advantages that could be gained through belonging to enterprise networks, only a few networks continue running businesses after the governments stop their funding. One of the reasons is the lack of a model that evaluates the benefits from the firm’s point of view. The objective of this work is to develop a model that estimates the benefits in horizontal collaborative networks, for ...

Simultaneous multithreading (SMT) and chip multiprocessing (CMP) both allow a chip to achieve greater throughput, but their thermal properties are still poorly understood. This paper uses Turandot, PowerTimer, and HotSpot to evaluate the thermal efficiency for a Power4/Power5-like core. Our results show that although SMT and CMP exhibit similar peak operating temperatures, the mechanism by whic...

Exploration and mapping are fundamental prerequisites for autonomous robots operating in initially unknown environments. In this paper, we evaluate simple yet efficient frontier-based exploration strategies. Furthermore, we discuss improvements to the classic frontier-based exploration strategy by Yamauchi et al. that further shorten the resulting exploration paths and present results from a co...
