... by the ratio of the frictional and normal impulses, are also derived. Its lower bound is negative, while its upper bound is equal to the kinetic coefficient of friction. Simplified bounds in the case of a nearly vertical impact are also derived. 02 10 2008 12 04 2009 24 09 2009 friction...

..., on the noise sources affecting the measurement, and on the performances of a noise optimal-filtering technique in terms of achievable measurement resolution. In the applications mentioned, the measured impulse is originated by a noncontact force , which may be electromagnetic or inertial (accelerated ions...
