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 theories used up to now to model theoretically and numerically nanostructures, and more specifically semiconductor heterostructures, do not allow to include efficiently at the envelope function level, in a k · p approach, the effects imposed by a possi ...
We present a symmetrization algorithm for geometric objects. Our algorithm enhances approximate symmetries of a model while minimally altering its shape. Symmetrizing deformations are formulated as an optimization process that couples the spatial domain wi ...
In this paper, we present further improvements in the subdomain multilevel approach (SMA), one of the techniques used for fast full-wave analysis of large printed antennas and circuits. The time for filling the method of moments (MoM) matrix is improved in ...
A no. of promising synthetic catalysts for the hydrolytic degrdn. of RNA have been developed in recent years. Some of them show remarkable selectivity for pyrimidine nucleotides. The general problem of all these studies is to distinguish between real effec ...
This chapter introduces the field of Mixed Reality that merges the real and virtual worlds seamlessly. To develop a Mixed Reality system, two fundamental problems should be addressed: tracking and user interface. Tracking in Mixed Reality is defined as the ...
As observed by variable-temperature and -pressure C-13 NMR, intramolecular carbonyl scrambling in Ir2Rh2(CO)(12) and Ir-4(CO)(11)(mu-SO2) proceeds via a 'change of basal face' mechanism. In both cases the site exchange process has a positive activation vol ...
Ce projet s’inscrit dans le cadre du projet européen de neurochirurgie PICO (Paraendoscopic Intuitive Computer assisted Operating system) auquel participe le groupe VRAI du LSRO. Le but de ce projet est de proposer une interface multimodale (voix + mouveme ...
We describe a tabletop environment used in vocational schools to teach theoretical concepts to apprentices in lo gistics through the use of a small-scale model of a ware house. It provides a Tangible User Interface in the form of wooden shelves, metallic p ...
Nowadays, computer interaction is mostly done using dedicated devices. But gestures are an easy mean of expression between humans that could be used to communicate with computers in a more natural manner. Most of the current research on hand gesture recogn ...
We record double resonance spectra of the 4nu(1) band of jet-cooled C-13-methanol using single rotational state selection in the nu(1) fundamental and subsequent promotion of the selected molecules to the fourth vibrational level. We then detect transition ...
