Peer-to-Peer (P2P) video streaming is the fastest growing application of the Internet. One of the main challenge is to provide a high quality of service through the dynamic behavior of the network because a peer may join or leave anytime. Currently, P2P streaming network exist two types of users: streaming users who use mobile devices with 3G/4G connection expect to watch the live video immedia...

We consider extensions and improvements on our previous work [1] on dynamic adaptive video streaming in a multi-cell multiuser “small cell” wireless network. In [1] we treated the case of single-antenna base stations and, starting from a network utility maximization (NUM) formulation, we devised a “push” scheduling policy, where users place requests to sequential video chunks to possibly differ...

To address the clinical problems of joint stiffness, acetabular pain, and component wear, recent bipolar heads have been designed to achieve increased inner bearing range of motion. We tested four designs to determine if this compromises component integrity. Inner bearing ranges of motion were determined and the components then mechanically tested to determine inner bearing pull-out disassociat...

A distributed modeling approach has been developed to describe the dynamic behavior of ring resonators. The model includes the effect of large amplitudes around primary resonance frequencies, material and electrostatic nonlinearities. Through a combination of geometric and material nonlinearities, closed-form expression for third-order nonlinearity in mechanical stiffness of bulk-mode ring reso...

The terms pull and lean production have become cornerstones of modern manufacturing practice. But, although they are widely used, they are less widely understood. In this paper, we argue that while the academic literature has steadily revealed the richness of the pull/lean concepts, the practitioner literature has progressively simplified these terms to the point where serious misunderstandings...
