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.
A method for preparing and observing clay platelets for size and shape analysis using scanning electron microscopy (SEM) was developed. Samples of the clay platelets were prepared by polyelectrolyte-assisted adsorption onto a pyrolytic graphite surface. Th ...
A technique for high resoln. anion photodetachment spectroscopy is presented that combines velocity map imaging and anion threshold photodetachment. This method, slow electron velocity-map imaging, provides spectral line widths of better than 1 meV. Spectr ...
Three-dimensional (3D) electron microscopy (3DEM) aims at the determination of the spatial distribution of the Coulomb potential of macromolecular complexes. The 3D reconstruction of a macromolecule using single-particle techniques involves thousands of 2D ...
The combination of synchrotron-based X-ray absorption and fluorescence computed tomographies (CT) is a new method allowing a noninvasive and nondestructive determination of the three-dimensional (3D) mineralogy with micrometer resolution of sub-millimeter ...
This thesis focuses on the rigid-body registration of a three-dimensional model of an object to a set of its two-dimensional projections. The main contribution is the development of two registration algorithms that use a continuous model of the volume base ...
The In composition is investigated in GaN/InGaN multi-quantum wells (QWs) by measurement of the local lattice distortion in high-resolution electron microscopy (HREM) images taken along the [1120] zone axis by image processing. The direct peak-finding proc ...
By means of transmission electron microscopy (TEM) the structure of chemically ordered regions in Zr-doped Pb(Mg1/3Ta2/3)O-3 has been studied. Large coherent ordered domains were obtained by the addition of 5 mol% PbZrO3. The results obtained by convention ...
An 8x4 avalanche diode array in a 0.8μm CMOS process uses single photon counting for time-of-light range finding with 100ps 40mW decollimated laser pulses. An accuracy of 618μm is achieved from 15cm to 1m with 10e4 pulses. ...
Based on spectral interferometry and wavelength multiplexing, we demonstrate that a combination of these methods could lead to a 3D imaging system. This system has the advantage of a one-dimensional geometry transmission channel and a limited scanning need ...
Intra-operative MR imaging is an emerging tool for image guided (neuro)surgery. Due to the small size of the magnets and the short acquisition time, the images produced by such devices are often subject to distortions. In this work, we show the particular ...
