Cross-flow turbines, also known as vertical-axis turbines, are attractive for power generation from wind and water currents. Some cross-flow turbine designs optimize unsteady fluid forces and maximize ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

Background: The extent to which fatigue is related to the velocity of shortening is still not fully understood. Objectives: To examine the effects of fatigue induced by maximal intensity exercise at ...
