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.

The Swiss experience on the wear of railway switches & crossings

Willem-Jan Zwanenburg

Using databases of the Swiss Federal Railways (SBB CFF FFS), statistical analyses are carried out on the expected lifetime of railway switches (points) & crossings and their respective components. The expected lifetimes are attributed to different paramete ...

Asymmetric Gaussian Multiple Descriptions and Asymmetric Multilevel Diversity Coding

Suhas Diggavi

We consider multiple description source coding problem with Gaussian source and mean squared error, for

K=3

descriptions. We obtain an outer bound for the rate region of the problem. We also derive an inner bound for the problem based on successively ref ...

Spillover Benefits of Fusion Energy Programme

Edgard Gnansounou, Denis Bednyagin

This paper aims to develop a novel methodological approach to evaluation of long-term large-scale research, development, demonstration and deployment (RDDD) programs in energy sector. Following the postulates of “new” endogenous growth theory we propose to ...

Rateless coding with partial CSI at the decoder

Michael Christoph Gastpar

A channel model for channels with unknown state and partial state information available causally at the decoder is proposed. The model is based on arbitrarily varying channels (AVCs), and the partial state information is characterized by allowing the decod ...

Plasma silane concentration as a determining factor for the transition from amorphous to microcrystalline silicon in SiH4/H-2 discharges

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Benjamin Strahm

In this work, the microstructure transition from amorphous to microcrystalline silicon is defined in terms of the silane concentration in the plasma as opposed to the silane concentration in the input gas flow. In situ Fourier transform infrared absorption ...

The effect of multifunctionality on the rate of evolution in yeast

Marcel Salathé, Martin Ackermann

Multifunctional genes are expected to evolve at lower rates because mutations in such genes that improve one function might often have deleterious effects on other functions. Here we tested for an association between multifunctionality and evolutionary rat ...

Physico-mechanical properties of Ultra High Performance Fibre Reinforced Concrete

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

The effect of different curing temperatures (from 20 to 40 °C) on the compressive strength and hydration of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) have been investigated between 3 and 28 days, using the loss on ignition test (LOI) and th ...

Improved echo volumar imaging (EVI) for functional MRI

Wietske Van der Zwaag

Echo volumar imaging (EVI) is a 3D modification of echo-planar imaging (EPI) that allows data from an entire volume to be acquired following a single RF excitation. EVI provides a high rate of volumar data acquisition, which is advantageous for functional ...

High count rates with total internal reflection fluorescence correlation spectroscopy

Theo Lasser, Kai Hassler

We achieved photon count rates per molecule as high as with commonly used confocal fluorescence correlation spectroscopy instruments using a new total internal reflection fluorescence correlation spectroscopy system based on an epi-illumination configurati ...

Fast Index Assignment for balanced N-Description Scalar Quantization

Pascal Frossard, Ivana Radulovic

In this paper, we address the design of any number of balanced descriptions using multiple description scalar quantization (MDSQ), based on fast index assignment. The proposed scheme has the advantages of low complexity, and the possibility of being extend ...
