A dynamic solid-phase microextraction (SPME) method to sample fresh headspace volatile compounds released during the grinding of roasted coffee beans was described and the analytical results using gas chromatography/mass spectrometry (GC/MS) and GC/olfactometry (GC/O) were compared to those of the conventional static SPME sampling methods using ground(More)
Cache memory is effective in bridging a growing speed gap between a processor and relatively slow external main memory. Almost all of today's commercial processors, not only high-performance microprocessors but embedded ones, have on-chip cache memories. However, energy consumption in the cache memory would approach or exceed 50% of the total consumption by(More)
Along with the growing diversity and complexity of real-time embedded systems, significance of real-time scheduling is increasing. Rate monotonic (RM) and earliest deadline first (EDF) are representative scheduling algorithms for periodic tasks. RM has a merit that tasks with high-priority (short-period) have small jitters and short response times. However,(More)
This study was designed to evaluate any adverse effect of a hot water extract of black soybeans (Glycine max (L.) Merr.), when administered to both sexes of Crj:CD(SD)IGS rats at dietary levels of 0 (control), 0.5, 1.5 and 5.0% (6 rats/sex/group). During the study, the treatment had no adverse effects on clinical signs, survival, body weights, and food and(More)
Giving tasks more urgent deadlines leads to shorter response times in EDF-based scheduling. This paper describes a technique that gives earlier deadlines by virtually advancing release times in the Total Bandwidth Server (TBS) context. This technique improves aperiodic tasks' responsiveness while it guarantees the schedulability of the system. Simulations(More)
