Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
The aim of this study is to develop new methods for landslides mapping and water resources protection and management using geotypes and GIS. The first part of this report deals with the conception and the use of a new methodology for groundwaters’ protecti ...
Hot cracking is a spontaneous failure of an alloy during solidification. It is a severe problem for casting industry as it reduces the productivity of cast houses and limits the range of alloys compositions that can be industrially produced. Hot tears occu ...
Al-Zn-Si alloy coatings are widely used for the corrosion protection of steel sheets. In addition to the favorable corrosion properties, the Al-43wt%Zn-1.6wt%Si coatings present several features which are of metallurgical interest. The first one is their s ...
The role of various parameters governing bond behavior is investigated in this paper taking advantage of a simple but efficient finite-element model, whose fundamental aspects are briefly recalled. Several well-documented test results on bond are examined ...
Hot tearing, one of the most severe defects observed in castings, is due to both tensile stresses and lack of interdendritic liquid feeding in the mushy zone. In order to predict this phenomenon, the two-phase averaged conservation equations for mass and m ...
This study, conducted by visits, interviews, and literature search, analyzes how vaccine manufacturers in Brazil and India access technologies for innovative vaccines: through collaborations with academia and research institutions, technology transfer agre ...
Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
We report on the use of the bulge test method to characterize the mechanical properties of miniaturized buckling mode dielectric elastomer actuators (DEA). Our actuator consists of a Polydimethylsiloxane (PDMS) membrane bonded to a silicon chip with throug ...
Presentation at the symposium investigating urban potential for development and renewal in the borough of Southwark. The symposium was a joint effort between the EPFL-lapa, and the London School of Economics - Cities Group, and was hosted by the Tate Moder ...
