Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Fluctuations of the frictional force arising from the stroke of a finger against flat and sinusoidal surfaces are studied. A custom-made high-resolution friction force sensor, able to resolve ...

Many physical sound field synthesis techniques have been studied. To implement these techniques, a large-scale reproduction system is usually required with a large number of loudspeakers, D/A ...
