Abstract Change of direction speed, reaction time, sprint and explosive strength are important factors that determine athletes’ performance in the majority sports. From practical standpoint, it is interest to investigate what extent they differ among athletes team individual We compared 7 handball, 11 basketball, 15 male table tennis players four time tests, 505 Agility test, 5m 20m sprints, sq...

A method is described for the sedimentation velocity analysis of solutions composed of macromolecular solutes of widely disparate size. In sedimentation velocity experiments, usually a single rotor speed is chosen for the entire run, and consequently, the range of observable sedimentation coefficients can be severely limited. This limitation can be removed if the speed is varied during the run,...

A system was evaluated for growing plants at reproducible levels of water stress. Beans (Phaseolus vulgaris L.) were grown in vermiculite, transferred to a semipermeable membrane system that encased the root-vermiculite mass, and then placed into nutrient solutions to which various amounts of polyethylene glycol (PEG) 20M were added to control solution water potential. The membrane (Spectrapor ...

In this paper, accuracy improvement in the displacement measurement systems using Dopplerinterferometry method is presented. The cross-talk error reduction methods are also discussed. Based on the mentioned method, a new nano-displacement measurement system is designed. In the designed system, the signal to leakage ratio for moving targets in the range of -20m/s to +20m/s is increased to 55dB. ...

The aim of this study was to determine the influence of run-up speed on take-off technique in the long jump. Seventy-one jumps by an elite male long jumper were recorded in the sagittal plane by a high-speed video camera. A wide range of run-up speeds was obtained using direct intervention to set the length of the athlete's run-up. As the athlete's run-up speed increased, the jump distance and ...

Reconfigurable computing is certainly one of the most important emerging research topics over the last few years, in the field of digital processing architectures. The introduction of run-time reconfiguration (RTR) on FPGAs requires appropriate design flows and methodologies to fully exploit this new functionality. For that purpose we present an automatic design generation methodology for heter...

To shorten time-to-market of VLSI circuit chips, the yield must be ramped up by quickly discovering and rectifying the causes for systematic defects. Due to the shrinking feature size of devices 90nm and below, yield ramp up is becoming more and more difficult. Volume diagnosis with statistical learning is needed to cost effectively discover systematic defects. An accurate and high throughput d...

This thesis investigates the feasibility of utilizing a run-time partially reconfigurable FPGA to implement a sequence of high-speed digital signal processing filters. Rather than reconfiguring the entire device to modify part of a configuration, a modular architecture is designed to allow smaller segments of the device to be individually reconfigured while the remainder of the device continues...
