Chattez avec Graph Search
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.
Through a collaborative research effort between the Ecole Polytechnique Federal de Lausanne and CIDEM a new kind of cementitious binder has been developed based on the synergy between calcined clays and limestone. Industrial trials carried out in Cuba duri ...
Sharding, or partitioning the system's state so that different subsets of participants handle it, is a proven approach to building distributed systems whose total capacity scales horizontally with the number of participants. Many distributed ledgers have a ...
The interest of German building masters towards hydraulic binders grows at the third decade of the 19th century. This acute interest is stimulated by the import of «Roman Cement» from England and by the acquisition of the knowledge related to it. The disse ...
The recent increase in organoid research has been met with great enthusiasm, as well as expectation, from the scientific community and the public alike. There is no doubt that this technology opens up a world of possibilities for scientific discovery in de ...
Autogenous shrinkage is the unrestrained volume change of cementitious materials occurring at con-stant temperature without any change in mass. It occurs as a consequence of self-desiccation (de-crease of internal relative humidity) and increasing capillar ...
Upon illumination, a dielectric microsphere (mu,S) can generate a photonic nanojet (PNJ), which plays a role in the super-resolution imaging of a sample placed in the mu S's immediate proximity. Recent microscopy implementations pioneered this concept but, ...

The objective of this report is to detail the work done during the TP IV project at EPFL. The idea is to look into the activation of concrete and metallic structures of the EPFL’s nuclear reactor: CROCUS. This study has been done by two ways: MCNP computat ...
At the turn of the 19th century, the production and use of concrete were limited by the unavailability of raw materials to produce good cement in several places. From that time onwards, the progress of chemistry and a number of empirical discoveries opened ...
Aggregate interlock is one of the most significant stress transfer actions in cracked concrete and its understanding is fundamental in order to predict the strength of many concrete structures, particularly members failing in shear. Several test programmes ...
