DG-FEM solution for nonlinear wave-structure interaction using Boussinesq-type equations

We present a high-order nodal Discontinuous Galerkin Finite Element Method (DG-FEM) solution based on a set of highly accurate Boussinesq-type equations for solving general water-wave problems in complex geometries. A nodal DG-FEM is used for the spatial d ...

Longshore sediment transport estimation using fuzzy inference system

Roham Bakhtyar

Accurate prediction of longshore sediment transport in the nearshore is essential for the control of shoreline erosion and beach evolution. In this paper, the abilities of an hybrid Adaptive-Network-Based Fuzzy Inference System (ANFIS), a Fuzzy Inference S ...

Tomography using multiple wavelengths in digital holography: Method, simulations and experiments

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Florian Charrière

In this paper we present a method for tomographic imaging using multiple wavelengths in digital holographic microscopy. This method is based on the recording at different wavelengths equally separated in the k-domain, in off- axis geometry of the interfere ...

CMOS pixels for subretinal implantable prothesis

Mihai Adrian Ionescu, Philippe Renaud, Marco Mazza

This work reports on the design, fabrication, and characterization of CMOS pixels for subretinal implants, which seems to be an effective way to recover visual capabilities in some types of blindness. Two possible approaches are presented for CMOS pixel im ...

A novel non-diffractive reconstruction method for digital holographic microscopy

Michaël Unser, Christian Depeursinge, Etienne Cuche, Thierry Blu, Pierre Marquet

We present a new method for reconstructing digitally recorded off-axis Fresnel holograms. Currently-used reconstruction methods are based on the simulation and propagation of a reference wave that is diffracted by the hologram. This procedure introduces ...

Water wave-driven seepage in marine sediments

David Andrew Barry

The action of water waves moving over a porous seabed drives a seepage flux into and out of the marine sediments. The volume of fluid exchange per wave cycle may affect the rate of contaminant transport in the sediments. In this paper, the dynamic response ...

Method for simultaneous amplitude and quantitative phase contrast imaging by adjusting reconstruction parameters for definition of digital replica of reference wave and aberration parameters correction digitally

Christian Depeursinge, Etienne Cuche

A method for the numerical reconstruction of digital holograms which allows simultaneously amplitude and quantitative phase contrast imaging. The reconstruction method computes the propagation of the field that would be diffracted by the hologram during a ...

Power laws for the spatial dependence of electrical parameters in the high-voltage capacitive RF sheath

Christoph Hollenstein, Alan Howling

Following the analytical description of the collisionless high-voltage capacitive RF sheath in Lieberman (1988) and of the collisional high-voltage capacitive RF sheath in Lieberman (1989), electrical sheath parameters are calculated for a square-wave ie R ...
