Many hardware cache prefetching mechanisms have been proposed to improve cache per formance Most of them rely on spatial locality prediction based on continuously monitoring miss addresses While this kind of spatial locality prediction is useful in reducing the num ber of capacity and compulsory misses it may not be e ective in reducing the number of con ict misses This paper presents the desig...

Tripping is presumed to be the principal cause for falls during walking. At minimum toe clearance, the potential for trip-related falls is considered to be highest. Thus, controlling minimum toe clearance is essential for walking without tripping. In theory, the central nervous system should therefore give priority to accurate control of the variability in minimum toe clearance, as compared to ...

Email: [email protected] In this study, we focused on the gait of Parkinson’s disease (PD) and presented a gray box model for it. We tried to present a model for basal ganglia structure in order to generate stride time interval signal in model output for healthy and PD states. Because of feedback ro...

Objectives: The Microsoft KinectTM is reported to have compelling potentials for gait analysis in medicine; however, there are few data on its comparison with observational gait analysis (OGA). This study compared the Microsoft KinectTM and the OGA in the assessment of gait parameters of apparently healthy adults. Methods: Ninety-seven apparently healthy young male adults participated in this ...

Since processor becomes faster and faster and memory system improves less, the access time of memory system becomes significantly important. To narrow the gap between processor and memory system, a more clever way of utilizing cache are needed. In this project, I’m trying to design a small device and algorithm to prefetch blocks from lower level memory to L1 D-cache efficiently and correctly. T...

BACKGROUND Walking is a complex cognitive motor task that is commonly completed while performing another task such as talking or making decisions. Gait assessments performed under normal and "dual-task" walking conditions thus provide important insights into health. Such assessments, however, are limited primarily to laboratory-based settings. OBJECTIVE The objective of our study was to creat...

Walking humans prefer to use the stride rate that results in the lowest rate of metabolic energy expenditure. Mechanical power requirements have been suggested to underlie the metabolic response, but mechanical power is consistently reported to be minimal at stride rates 20-30% lower than preferred. This may be due to limitations in how total mechanical power has been computed, as well as a fai...

The kinematics of the hindlimb during terrestrial treadmill locomotion in Dicamptodon tenebrosus were compared between larval and metamorphosed individuals at different speeds. Coordinates of marker points on the salamander's midline, pelvic girdle and left hindlimb were digitized from high-speed videos (200 fields s-1). These yielded kinematic variables describing trunk flexion, pelvic girdle ...
