Graph Chatbot

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.

Shot noise influence in reconstructed phase images SNR in digital holographic microscopy

Christian Depeursinge, Etienne Cuche, Pierre Marquet, Florian Charrière

We present a study based on simulations describing how shot noise, an intrinsic part of the recording process with a digital camera, influences the quality of the reconstructed phase images under different beams intensities configurations. ...

Uniform magnetic properties for an ultrahigh-density lattice of noninteracting Co nanostructures

Harald Brune, Stefano Rusponi, Nicolas Weiss

We report on the magnetic properties of two-dimensional Co nanoparticles arranged in macroscopically phase-coherent superlattices created by self-assembly on Au(788). Our particles have a density of 26 Tera/in(2) (1 Tera=10(12)), are monodomain, and have u ...

Sociometry Based Multiparty Audio Recordings Segmentation

Alessandro Vinciarelli

This paper shows how Social Network Analysis, the sociological domain studying the interaction between people in specific social environments, can be used to assign roles to different speakers in multiparty recordings. The experiments presented in this wor ...

Clustering And Segmenting Speakers And Their Locations In Meetings

Guillaume Lathoud, Jitendra Ajmera

This paper presents a new approach toward automatic annotation of meetings in terms of speaker identities and their locations. This is achieved by segmenting the audio recordings using two independent sources of information : magnitude spectrum analysis an ...

Intraocular pressure recording system

Stefan Metz, Matteo Leonardi

A new noninvasive approach for intraocular pressure (IOP) measurement allowing continuous monitoring over prolonged periods, regardless of patient's position and activities. The key element of this measurement method is a soft contact lens (1) including at ...

The VidTIMIT Database

This communication describes the multi-modal VidTIMIT database, which can be useful for research involving mono- or multi-modal speech recognition or person authentication. It is comprised of video and corresponding audio recordings of 43 volunteers, recit ...

Storage density of shift-multiplexed holographic memory

Demetri Psaltis

The storage density of shift-multiplexed holographic memory is calculated and compared with experimentally achieved densities by use of photorefractive and write-once materials. We consider holographic selectivity as well as the recording material's dynami ...

Chip based biosensor for functional analysis of single ion channels

Horst Vogel

The functional anal. of single ion channel proteins presents a serious bottleneck in the process of finding new pharmacol. active compds. Currently available single channel recording methods are not suited for automation and miniaturization. However, new t ...

Diffraction efficiency of localized holograms in doubly doped LiNbo(3) crystals

Demetri Psaltis

The diffraction efficiency of M holograms superimposed in the volume of the recording medium is proportional to 1/M-2, me present a method, based on nondestructive localized holograms in a doubly doped LiNbO3 crystal, that allows us to also record M hologr ...
