These years are close to those of the influenza pandemics of the period 1890-1930. The estimated risk of an ind...
متن کاملImproving Energy Efficiency Via Speculative Multithreading on MultiCore Processors
The advance in semiconductor technologies has increased the number of transistors on a die, resulting in the continuous improvement in microprocessor performance. However, the increase in power consumption and hence in power density is about to stop the progress in microprocessor performance. While supply voltage reduction is commonly known as an effective technique for power savings, it increa...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
