Multi-Supply voltage design using Cluster Voltage Scaling (CVS) is an effective way to reduce power consumption without performance degradation. One of the major issues in this method is performance and power overheads due to insertion of Level Converting Flip-Flops (LCFF) at the interface from low-supply to high-supply clusters to simultaneously perform latching and level conversion. In this p...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
Polyphase channelizer is an important component of subband adaptive filtering systems. This paper presents an energy-efficient hardware architecture and VLSI implementation of polyphase channelizer, integrating algorithmic, architectural and circuit level design techniques. At algorithm level, low complexity polyphase channelizer architecture is derived using multirate signal processing approac...
Portable digital systems tend to be not just low power but power efficient as they are powered by low batteries or energy harvesters. Energy harvesting systems tend to provide nondeterministic, rather than stable, power over time. Existing memory systems use delay elements to cope with the problems under different Vdds. However, this introduces huge penalties on performance, as the delay elemen...
Background: Vitamin D deficiency (VDD) is prevalent in polycystic ovary syndrome (PCOS) and the relationship between dyslipidemia vitamin status close. This meta-analysis was to evaluate effect of (alone or with co-supplementation) on lipid profile PCOS patients.
In most myogenic systems, synthesis of the intermediate filament (IF) protein vimentin precedes the synthesis of the muscle-specific IF protein desmin. In the dorsal myotome of the Xenopus embryo, however, there is no preexisting vimentin filament system and desmin's initial organization is quite different from that seen in vimentin-containing myocytes (Cary and Klymkowsky, 1994. Differentiatio...
BACKGROUND AND AIM To conduct meta-analyses of all published studies on various aspects of association between vitamin D and tuberculosis (TB). METHODS PubMed and Web of Knowledge were searched for all properly controlled studies on vitamin D and TB. Pooled odds ratio, mean difference or standardized mean difference, and its corresponding 95% confidence interval were calculated with the Cochr...
Background Clinical research has recently demonstrated that vitamin D deficiency (VDD) is highly prevalent in the pediatric intensive care unit (PICU) and associated with worse clinical course. Multiple adult ICU trials have suggested that optimization of vitamin D status through high-dose supplementation may reduce mortality and improve other clinically relevant outcomes; however, there have b...
