Walking around the preferred speed: examination of metabolic, perceptual, spatiotemporal and stability parameters
منشور في 2024"…Results indicated a significant main effect of speed on all studied variables. While metabolic, perceptual and spatiotemporal values were sensitive to the smallest change in speed (i.e., 0.5 km·h<sup>−1)</sup>, a significant increase in the rate of carbohydrate oxidation and decrease in % fat oxidation were only observed at speeds above PWS. …"

Measurements of roll, steering, and the far-field wake in track cycling
منشور في 2022"…The accuracy of the roll angle calculations is dependent on the fidelity of the modelled cyclist path and decreases for higher riding speeds. Experimental measurements of the steering angle show a reasonable agreement to theoretical calculations, albeit with reduced steering angles on the bends at higher speeds. …"

A control algorithm to increase the efficient operation of wind energy conversion systems under extreme wind conditions
منشور في 2022"…<p dir="ltr">This paper aims to increase the power production of gearless permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) in strong (greater than 25 m/s) wind speed regions. In general, most wind turbines cut off when wind speed is over the cut-out rate; as a result, the power generation of the wind farm decreases. …"

Credit bureaus and financial constraints do corruption matter?
منشور في 2022"…The estimation outcomes suggest that countries with higher levels of corruption might produce less transparent and falsified information that would make access to sources of financing more difficult for firms. Our findings suggest that curbing corruption creates more efficient credit bureaus that, in turn, decrease financial constraints for firms. …"
