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 reactions of dolomite with portlandite have been studied at well-spaced temperatures between 20 degrees C and 85 degrees C using XRD Rietveld, TG and SEM methods. The results show quantitatively the faster rates of reaction at higher temperature. Isoth ...
Adsorption of N-2 at 77 K and scanning electron microscopy have been used to measure the changes in the support morphology, at nano- and microscale level, along the processes involved in the preparation of a supported Pd catalyst: Pd deposition, doping, an ...
Developing modern software applications typically involves composing functionality from existing libraries. This task is difficult because libraries may expose many methods to the developer. To help developers in such scenarios, we present a technique that ...
Calcium-containing slag material is produced in iron- and steelmaking worldwide, including Finland. One process route utilizing this calcium, being developed towards large-scale application, is the so-called slag2pcc concept. Using ammonium salts, up to 50 ...

Several Hall sensor configurations have been integrated in CMOS 0.35 mu m technology and analyzed in terms of offset at room temperature and offset drift. We searched for the best geometry that would minimize the offset and its corresponding drift. The tar ...
Calcite isocrinid ossicles from the Middle Jurassic (Bathonian) clays in Gnaszyn (central Poland) show perfectly preserved micro- and nanostructural details typical of diagenctically unaltered echinoderm skeleton. Stereom pores are filled with ferroan calc ...
Calcium silicate hydrate (C-S-H) is the main hydrate phase in Portland cements. Its composition
varies depending on the Ca/Si ratio and on the presence of other ions such as aluminium (called CA-
S-H) or alkalis.
This thesis aimed to study the compositi ...
We introduce a suitable concept of weak evolution in the context of the radial quintic focussing semilinear wave equation on R^{3+1}, that is adapted to continuation past type II singularities. We show that the weak extension leads to type I singularity fo ...
A fertilisation experiment was started in the French Alps on an acid grassland at 2000 m in 1989 where lime as calcium carbonate ("liming") and Thomas Slag enriched by potassium chloride ("fertilisation") were added in a random block design until 1992. Sin ...
This work constitutes the first extended analysis of the spatial structure of Type-I ELM filament footprints on the JET outer limiters and upper dump plates. The data is obtained using a wide angle infrared diagnostic (with time resolution of 125 Hz) and c ...
