Evaluating predictive performance of sensor configurations in wind studies around buildings

Ian Smith, Maria Papadopoulou

A great challenge associated with urban growth is to design for energy efficient and healthy built environments. Exploiting the potential for natural ventilation in buildings might improve pedestrian comfort and lower cooling loads, particularly in warm an ...

Elsevier2016

Wear is a key problem limiting the lifetime and performance of total hip arthroplasty. The synovial fluid, acting as lubricant, can alleviate the wear of implants but also introduces corrosion. The interaction of mechanical wear and electrochemical corrosi ...

Wear at the asperity level: An atomistic viewpoint

Jean-François Molinari, Ramin Aghababaei, Derek Warner

Tribological problems are particularly difficult to comprehend. Different physical mechanisms (including the environment, plastic deformation, third body interactions, phase transformations, recrystallization) interact at disparate length and time scales. ...

FUTURE POWER POWERING FUTURE: HIGH-PERFORMANCE TRIBOELECTRIC NANOGENERATOR FOR WEARABLE ELECTRONICS

Jürgen Brugger, Xiao Sheng Zhang

This abstract summarized the reported research work on the high-performance triboelectric nanogenrator (TENG) for wearable electronics. The requirement of TENG for wearable electronics was illustrated firstly, and then the developing tendency of flexible T ...

FE modeling of micromotion at the bone-implant interface

Denis Stauffer

Nowadays, pain and mobility issues of the hip such as arthritis bring more and more people to go through a hip replacement. The primary stability of an implant is essential for the long-term success of hip arthroplasty. Excessive micromotion is an indicato ...

Tribo-electrochemical characterization of metallic biomaterials for total joint replacement

Stefano Mischler

Knee and hip joint replacement implants involve a sliding contact between the femoral component and the tibial or acetabular component immersed in body fluids, thus making the metallic parts susceptible to tribocorrosion. Micro-motions occur at points of f ...

Fretting-corrosion behavior of beta titanium alloys in simulated synovial fluid

Stefano Mischler

Fretting-corrosion is a material degradation process resulting from the combined action of a corrosive environment and small displacement fretting wear. In this work, the fretting-corrosion behavior of Ti-12.5Mo, Ti-13Nb-13Zr, and Ti-29Nb-13Ta-4.6Zr, beta ...

Multipactor prediction in Multi-carrier Systems

Michael Mattes

This communication reports the status of the activity corresponding to the ESTEC contract ”RF Breakdown in Multicarrier Systems” (19918/06/NL/GLC/RF). The main objective of this activity is to propose alternatives to the 20-gap-crossing rule for multipacto ...
