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.
Correlations between adhesion hysteresis and local friction are theoretically and experimentally investigated. The model is based on the classical theory of adhesional friction, contact mechanics, capillary hysteresis, and nanoscale roughness. Adhesion hys ...
In order to make the transfer of biological principles to engineering problems successful, it is important to study the fundamental properties of biological systems. The goal is to arrive with useful abstractions that are (1) implementable, (2) testable by ...
Our research is centered on the engineering of structures at the mesoscopic length scale. Patterns between the micrometer and nanometer bridge molecules and biological cells to microelectronics and microsystems, and further to the macroworld, and vice vers ...
To characterize the boundary layer development, in the cone of the Francis turbine, wall friction and velocity measurements are performed. The mean wall friction measurements evidence the increasing risk of the boundary layer separation at the cone wall wi ...

Bioremediation: Applied Microbial Solutions for Real-World Environmental Cleanup is a fascinating examination of research and its real-world application. Intended for both academics and practitioners, the book presents information on the legal, scientific, ...
Spent railway ballast is a source of recycled aggregate. Recycling of aggregates contributes to sustainable development by reducing the volume of construction waste going to landfill, reducing transportation and reducing the impact of primary mineral extra ...
Geotechnical centrifuge testing is used to examine the preferential (fingered) flow of a nonaqueous phase liquid (NAPL) in a uniform dry sand. The results of nine experiments, containing a total of 87 observations of NAPL finger behavior, are analyzed. The ...
Railway ballast consists of crushed aggregate and serves as foundation and drainage for railway tracks. Over time, ballast loses its geotechnical properties and cannot be reused within the rail industry but can be sold on to other users to be utilized as a ...
We present some results on coupling Navier-Stokes with shallow water equations for surface flows, and with Darcy's equation for groundwater flows. We discuss suitable interface conditions and show the well-posedness of the coupled problem in the case of a ...
Traditional large-eddy simulation (LES) provides good results on standard benchmark turbulent flows, but engineering applications involving more complex geometries are restricted. This is mainly due to the physical hypotheses of homogeneity, isotropy, or l ...
