INTRODUCTION Although total elbow arthroplasty (TEA) is a clinically successful procedure, long-term complications due to bushing wear and osteolysis are a few of the reasons for limited long-term survivorship.[Goldberg, 2008] There is no published information on in vitro wear simulations of total elbow prostheses to characterize and predict in vivo performance nor are there any currently accep...

Development of the power grid towards a more reliable and smarter system requires frequent on-line monitoring of the power components. Power transformers and their bushings are particularly important components in a power transmission system and their insulation degradation may lead to catastrophic failures. Time consuming and costly replacement of these components raise the importance of their...
