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 craze formation and failure typical of many glassy polymers have been investigated using an elastic spring network to model both bulk and crazed polymer material. The elastic properties of the network springs were modified, using simple rules, to captu ...
AIM: To propose a method for obtaining non-invasive highly accurate measurements of arterial diameter, thickness and pressure at a single location on a peripheral arm artery, and use this data to estimate the status of the arterial wall. METHODS: Diameter ...
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 elastic properties of carotid arteries of spontaneously hypertensive rats (SHR) and normotensive controls (Wistar-Kyoto rats [WKY]) were examined in vivo, in situ, and in vitro. The changes of internal diameter were measured with a high-resolution A-mo ...
The effect of an elastic deformation on optical properties of an aeolotropic medium (piezo-optic effect) is explicitly established from an energy function. Then is deduced the number of distinct coefficients ruling this effect in the special case of quartz ...
In this paper, the stability of a displacement sensor assembled with Sn96 (tin- silver) solder, Sn62 (tin-leadsilver) solder or conductive silver-loaded epoxy glue was compared. In the absence of humidity or thermal cycling, the glue was found to be much b ...
The growth of highly strained InxGa1-xAs (x > 0.25) epitaxial layers on GaAs(001) undergoes a 2D-3D growth mode transition beyond a certain ''critical thickness''. As suggested previously, it has been found that the driving force of this transition is the ...
We propose a new, simple way of constructing elastic tubes which can be used to model the nonlinear elastic properties of large arteries. The tube models are constructed from a silicon elastomer (Sylgard 184, Dow Corning), which exhibits a nonlinear behavi ...
