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. …"

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. …"

Evapotranspiration and water availability response to climate change in the Middle East and North Africa
منشور في 2021"…Outcomes reveal that the MENA region is indeed vulnerable to a surge in temperature, which can increase evapotranspiration losses and decrease water availability. Under the shared socioeconomic pathway (SSP2-4.5), the potential evapotranspiration (PET) has been projected to increase throughout the MENA region by up to 0.37 mm per year during the middle of the twenty-first century (2021–2050) and by up to 0.51 mm per year during the end of the twenty-first century (2071–2100). …"
