Slowdown factors determine the extent of slowdown that a computing system can experience based on functional and performance requirements. Dynamic voltage scaling (DVS) of a processor based on slowdown factors can lead to considerable energy savings. This paper addresses the problem of DVS in the presence of task synchronization. Tasks synchronize to enforce mutually exclusive access to the shared resources and can be blocked by lower priority tasks. Task slowdown factors that guarantee meeting all task deadlines are computed. Both static and dynamic priority scheduling viz. rate monotonic (RM) scheduling and earliest deadline first (EDF) scheduling, respectively, are studied.

'Time and thyme are not homophones', a 2008 article by Susanne Gahl published in Language, reports a frequency effect differentiating the durations of homophones, for example, time vs. thyme. The article is of fundamental theoretical relevance, as the finding reported has significant implications for research on homophones and the effects of frequency in general. As I show in the present paper, however, the main analysis in Gahl 2008 does not provide quantitative evidence for the effect. The same is true of a follow-up study (Gahl 2009). I provide here a reanalysis based on the original data set, which shows that the frequency effect reported in the original article is real.*
