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.
Genotypic analysis was performed on 48 Mycobacterium tuberculosis complex strains collected from a hospital in Dhaka city. Deletion analysis showed that the isolates were all M. tuberculosis; 13 of them were found to be of the "ancestral" type, while 35 we ...
The electronic structures of different phosphates were studied by using the DV-X alpha cluster molecular orbital method, Experimental data on crystal structures from x-ray diffraction measurements were used to set up realistic model clusters. Theoretical X ...
Microscopic processes induced by the controlled deposition of mass selected silver clusters on graphite (HOPG) and Pt(111) are investigated. The implantation of silver clusters into the HOPG surface is analyzed. The first step consists in a systematic stud ...
Reaction of [Ru6C(CO)16]2− with an excess of AgX (X = Cl, Br or I) affords heteronuclear clusters of formula [{Ru6C(CO)16Ag2X}2]2− in 80% yield, which for X = I and X = ...
The energy levels of (TiO2)2, (TiO2)3, and (TiO2H)2 clusters were calcd. using ab initio SCF methods considering both crystal and relaxed geometries. Systematic changes in the valence-level resulting from geometry relaxation are found, which may be related ...
Equilibrium geometries and electronic properties of neutral Cu-n (n = 2, 3, 4, 6, 8, 10) clusters are determined via first principles calculations which treat s and d electrons on an equal footing. Overall, we find ground state and local minimum structures ...
An HMM-based speaker clustering framework is presented, where the number of speakers and segmentation boundaries are unknown \emph{a priori}. Ideally, the system aims to create one pure cluster for each speaker. The HMM is ergodic in nature with a minimum ...
A comparison of photoemission spectra from Ag clusters deposited on silicon oxide and on cleaved silicon substrate has allowed us to discriminate initial and final state effects in the binding energies of the valence band and of the 3d core level of the me ...
In nanocatalysis, clusters deposited on solid, well-defined surfaces play an important role. For the detection of size effects it is, however, important to prepare samples consisting of deposited clusters of a single size, as their chemical properties chan ...
