The equation of motion of a discrete linear system has the form of a second-order ordinary differential equation with three real and square coefficient matrices. It is shown that, for almost all ...

In addition to Fitts’ Law, we (Schmidt, Zelaznik, Hawkins, Frank & Quinn, 1979) proposed a linear speed-accuracy trade-off. These two laws appear to be fundamentally different. We have begun a series ...

Computer scientists have devised an innovative and elegantly concise algorithm that can efficiently solve systems of linear equations that are critical to such important computer applications as image ...
