A Low-Inertia and High-Stiffness Cable-Driven Biped Robot: Design, Modeling, and Control

Mathematics
In this paper, a biped robot system for dynamic walking is presented. It has two 2-degree-of-freedom (DOF) lightweight legs and a 6-DOF hip. All the joint pulleys of the legs are driven by motors that are placed at the hip using steel cables.

Combined Management of Meniscus Root Tear and High Tibial Osteotomy: A Surgical Strategy Using 3‐Dimensional Printing [PDF]

Arthrosc Tech
Abstract Combining high tibial osteotomy with meniscal posterior root repair is technically challenging because of the limited metaphyseal bone stock, the proximity of the transtibial tunnel to the osteotomy site, and the risk of implant conflict or tibial fracture.

Tribocorrosion of total hip replacements [PDF]

, 2012
The performance of metal-on-metal total hip replacements is largely determined by their propensity to degrade in vivo. Degradation occurs through the complex interactions between wear and corrosion (termed tribocorrosion) and leads to the production of ...
