Multiscale Modeling of Thermo-Mechanical Coupling Between Atomistic and Continuum Domains

The motivation to study multiscale problems such as friction and crack propagation/nucleation has triggered the development of multiscale models. The state-of-the-art multiscale models that have been developed until today are successfully applied to a vari ...

Spatially Dispersive Graphene Single and Parallel Plate Waveguides: Analysis and Circuit Model

Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

The propagation of surface waves along spatially dispersive graphene-based 2-D waveguides is investigated in detail. Graphene is characterized using a full-k(rho) conductivity model under the relaxation-time approximation, which allows to obtain analytical ...

Surface Plasmons on Graphene Sheets: Effect of Spatial Dispersion and Magnetostatic Bias

Juan Ramon Mosig, Julien Perruisseau-Carrier

We study the characteristics of surface plasmons propagating along graphene sheets, focusing on the effect of spatial dispersion and applied magnetostatic bias, and taking into account the influence of the surrounding media, applied electrostatic biasing f ...

Spatial filters for bridging molecular dynamics with finite elements at finite temperatures

Jean-François Molinari, Guillaume Anciaux, Srinivasa Babu Ramisetti

We present the application of digital filters to split the energy spectrum of an atomistic zone simulated with molecular dynamics into low and high energy components. After a brief background on digital filters, we describe the procedure used to select a c ...

Fano Resonances in Plasmonic Nanostructures

Benjamin Gallinet

Surface plasmons are able to generate extremely strong and confined optical fields at a deep-subwavelength scale, far beyond the diffraction limit, and now play a central role in nanosciences. A proper combination of plasmonic nanostructures can support Fa ...

Discovering relevant spatial filterbanks for VHR image classification

Devis Tuia

In very high resolution (VHR) image classification it is common to use spatial filters to enhance the discrimination among landuses related to similar spectral properties but different spatial characteristics. However, the filters types that can be used ar ...

Efficient Discriminative Projections for Compact Binary Descriptors

Vincent Lepetit, Tomasz Piotr Trzcinski

Binary descriptors of image patches are increasingly pop- ular given that they require less storage and enable faster processing. This, however, comes at a price of lower recognition performances. To boost these performances, we project the image patches t ...

On the Relevance of Sparsity for Image Classification

Pascal Fua, Engin Türetken, Vincent Lepetit, Germán González Serrano, Roberto Rigamonti, Matthew Brown, Fethallah Benmansour

In this paper we analyze empirically the importance of sparsifying representations for classification purposes. We focus on those obtained by convolving images with linear filters, which can be either hand designed or learned, and perform extensive experim ...

Spatio-Chromatic Decorrelation by Shift-Invariant Filtering

Pascal Fua, Sabine Süsstrunk, Matthew Brown

In this paper we derive convolutional filters for colour image whitening and decorrelation. Whilst whitening can be achieved via eigendecomposition of the image patch covariance, this operation is neither efficient nor biologically plausible. Given the shi ...

Low-Power and Widely-Tunable Linearized Biquadratic Low-Pass Transconductor-C Filter

Seyed Armin Tajalli, Yusuf Leblebici

A sixth-order low-pass

g_m

-C filter with a very wide tuning range (

f_c

= 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks. A single stage folded-cascode transcon ...
