AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This study presents an analytical model of the dynamics of an axisymmetric liquid bridge confined between two circular pads and subjected to small vertical periodic perturbations. Such system finds important applications in microassembly and microjoint des ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
Nanochannel conductance measurements are commonly performed to characterize nanofluidic devices Theoretical analysis and experimental investigations imply that the nanochannel conductance does not follow the macro-scale models. It is generally accepted tha ...
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 ...
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 ...
