We present an experimental validation of a recently proposed solution to the problem of finding the input torque command that provides rest-to-rest motion in a given time for a one-link flexible arm. The basic idea is to design an auxiliary output such that the associated input-output transfer function has no zeros. Planning a smooth interpolating trajectory for this output imposes a unique res...

Regulation of horizontal mergers now starts from the presumption that "the vast majority of horizontal mergers pose no market power problems and should simply be approved rapidly" (Schmalensee 1987, p. 44).
