Non-Cartesian actuators are improving applications where they weren't even feasible before. Full definition of their dynamics and kinematics helps designers extract maximum performance from these ...

Kinematics Equation: The branch of physics that defines motion concerning space and time, ignoring the cause of that motion, is known as Kinematics. Kinematics equations are a set of formulas used in ...

The topic and arguments concerning mechanical vs. kinematic alignment of knee replacements can be confusing the first few times you read about it. This month I asked Stephen M. Howell, MD, to respond ...
