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 ...

3D angle: angle between the mechanical axes before and after derotation.

When multi-joint reaching movements are made within a rotating reference frame, additional interaction torques are generated in the form of Coriolis forces. Coriolis forces are a function of the cross ...

George Spagna, chair of the physics department at Randolph-Macon College, explains. Stars and planets form in the collapse of huge clouds of interstellar gas and dust. The material in these clouds is ...
