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.

Sudden drawdown and drainage of a horizontal aquifer

David Andrew Barry, Marc Parlange

Drainage of a saturated horizontal aquifer following a sudden drawdown is reanalyzed using the Boussinesq equation. The effect of the finite length of the aquifer is considered in detail. An analytical approximation based on a superposition principle yield ...

2001

We present a general 3-D spectral collocation method for the analysis of diffractive optical elements (DOEs). The method computes a direct solution to the Maxwell's equations in the time domain. The computational domain is decomposed into a number of small ...

SPIE2000

Diffractive optical elements comprising sub-wavelength aperiodic surface reliefs of finite length require the use of rigorous solvers for Maxwell's equations. We present a detailed analysis of Focusing Grating Couplers (FGC's) using a recently introduced 2 ...

Policy optimization for dynamic power management

Giovanni De Micheli, Luca Benini

Dynamic power management schemes (also called policies) reduce the power consumption of complex electronic systems by trading off performance for power in a controlled fashion, taking system workload into account. In a power-managed system it is possible t ...

Generalized field propagator for arbitrary finite-size photonic band gap structures

Olivier Martin

We investigate the properties of photonic band gap structures of finite size and arbitrary geometry using the density of states deduced from scattering calculations. We first demonstrate this procedure on a finite 2D array of cylinders and then study at op ...

American Physical Society1999

In this paper, the authors further validate a theory presented previously by themselves for evaluating currents induced by external electromagnetic fields on a finite-length horizontal wire above a perfectly conducting ground. They present an approach to g ...

1996

A system of integral-differential equations for evaluating currents and voltages induced by external electromagnetic fields on a finite-length horizontal wire above a perfectly conducting ground is derived under the thin wire approximation. Based on pertur ...

A time-domain iterative approach to correct the transmission line approximation for lines of finite length

Michel Ianoz

We present an iterative approach to correct the results obtained using the transmission line (TL) approximation for lines of finite length above a perfectly conducting X ground. The method can be applied both in the frequency- and in the time-domain. The p ...

1994

The one-dimensional solute transport is analyzed with the convection-dispersion model, including first and zeroth order irreversible reaction. A simple analytical expression is derived for the residence concentration which depends explicitly on the exit co ...
