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 pathophysiology of the restless legs syndrome (RLS) is poorly understood. One index symptom is the urge to move, increasing at night. It is largely accepted that movement in RLS is "involuntary" and that the generators are below the level of the neocor ...
The equilibrium rheological properties of a range of isotropic exfoliated and intercalated hyperbranched polymer (HBP)/montmorillonite (MMT) clay nanocomposites have been investigated using low strain oscillating shear measurements at temperatures above th ...
The effects of the size (pseudo-generation number) and nature of end groups on physical and rheological properties were investigated for a series of hyperbranched polyesters based on an ethoxylated pentaerythritol core and 2,2-bis-(hydroxymethyl) propionic ...
Experiments on vortex shedding from a cylinder placed in uniform flows of low concentration polymer solutions are reported for Reynolds numbers from 50 to 150. The fluids used were aqueous solutions of polyethylene oxide (PEO) and rheological characterizat ...
The aim of this thesis has been to assess the potential of branched polymers as novel exfoliants for layered silicates and their application in polyurethanes. Three different types of –OH functional branched polymers have been studied: dendrimers, hyperbra ...
This project explores a new approach in the automatic calibration of a structured light system without need of prior knowledge neither on the intrinsic or extrinsic parameters of the camera and projector, nor on the environment. ...
We synthesized molecules containing one or two dendritic segments and a rigid-rod-like segment with their structures in the solid state. The molecules with rod-dendron or dendron-rod-dendron architecture had biphenyl ester rigid segments and 3,4,5 tris(re- ...
Next Generation Business Handbook offers strategies for the next generation of business success from the best business schools around the world. * Presents fresh ideas from the young, up-and-coming business thinkers and experts from the world's best busine ...
When the effects of physical aging below Tg are erased, the rheological response of a series of aliphatic hyperbranched polyesters is Newtonian and the melt viscosity scales roughly linearly with Mw at high Mw, indicating entanglement to be absent. The rhe ...
The use of a tetrafunctional epoxy-based additive to modify the molecular structure of poly(ethylene terephthalate) (PET) was investigated with the aim of producing PET foams by an extrusion process. The molecular structure analysis and shear and elongatio ...
