The stability of multi-input and multi-output web-tension systems is an important factor that is required for the roll-to-roll printing machines. This paper analyzes stability for design parameters of a web-tension system of a high-speed gravure printing machine. Analyzed parameters include moment of inertia of the passive dancer, viscous friction coefficient of the dancer system, distances fro...

Dancers spend a lot of time in the relevé position in demi-pointe and en pointe in their training and their careers. Pain from both osseous and soft tissue causes may start to occur in the posterior aspect of their ankle. This article reviews the potential causes of posterior ankle impingement in dancers. It will discuss the clinical evaluation of a dancer and the appropriate workup and radiogr...

This paper discusses a novel method to compensate the eeects of exibil-ity in belt-driven drive trains. Such drives are found in robot manipulators, for example, where drive exibility is undesirable. In some situations, band-width limitations can make exibility diicult to compensate using the primary actuator. In others, the control for the primary actuator is pre-deened and cannot be easily al...
