A new, open-loop, reduced order model is proposed for the swash plate dynamics of an axial piston pump. The difference from previous reduced order models is the modeling of a damping mechanism not reported previously in the literature. An analytical expression for the damping mechanism is derived. The proposed reduced order model is validated by comparing with a complete nonlinear simulation of the pump dynamics over the entire range of operating conditions.

In this paper, we present a first exposition of an automatic closed captioning system designed to assist hearing impaired users in telemedicine. This system automatically separates telehealth conversation speech between a health care provider and a client into two streams and provides real-time captions of health care provider's speech to client. The captioning system is based on the state-of-the-art technology of large vocabulary conversational speech recognition, encompassing speech stream separation, acoustic modeling, language modeling, real-time decoding, confidence annotation, and human-computer interface, with innovations made in several components. The system currently handles a vocabulary size over 46 K. Real-time captioning performance at the average word accuracy of 77.95% is reported.

A stable strain feedback control design is proposed for a flexible two-link manipulator using a model with partial differential equations directly. Stability is established using a Lyapunov-based design.
