A seamless reduced basis element method for 2D Maxwell's problem: An introduction

We present a reduced basis element method (RBEM) for the time-harmonic Maxwell's equation. The RBEM is a Reduced Basis Method (RBM) with parameters describing the geometry of the computational domain, coupled with a domain decomposition method. The basic i ...

Adaptive Finite Element Methods for Multiscale Partial Differential Equations

Achim Nonnenmacher

Engineers rely on efficient simulations that provide them with reliable data in order to make proper engineering design decisions. The purpose of this thesis is to design adaptive numerical methods for multiscale problems in this spirit. We consider ellipt ...

Deformable shape models for 2D object segmentation

Robin Thandiackal

Given a set of images showing individual 2D instances of an object class, the goal is to learn object class deformation in 2D for segmentation automatically. Class deformation is modelled by linear combinations of basis shapes. Usually, given segmentation ...

Dense Disparity Estimation from Linear Measurements

Pascal Frossard, Vijayaraghavan Thirumalai

This paper proposes a methodology to estimate the correlation model between a pair of images that are given under the form of linear measurements. We consider an image pair whose common objects are relatively displaced due to the positioning of vision sens ...

Sparse Image Restoration Using Iterated Linear Expansion of Thresholds

Thierry Blu, Hanjie Pan

We focus on image restoration that consists in regularizing a quadratic data-fidelity term with the standard l1 sparse-enforcing norm. We propose a novel algorithmic approach to solve this optimization problem. Our idea amounts to approximating the result ...

The SLICOT Toolboxes for Matlab | Die SLICOT-Toolboxen für Matlab

Daniel Kressner

SLICOT is a comprehensive numerical software package for control systems analysis and design. While based on highly performant Fortran routines, Matlab and Scilab interfaces provide convenient alternative access for users. In this survey, we summarize the ...

Modeling and Flatness of Rigid and Flexible Cable Suspended Underactuated Robots

Philippe Müllhaupt, Basile Graf

A modeling framework is proposed for the control of rigid and flexible cable-like systems such as cranes, together with a systematic algorithm for computing flat outputs of mechanical systems for which the flat output is a linear combination of the free co ...

Repeater Insertion Techniques for 3D Interconnects

Giovanni De Micheli, Vasileios Pavlidis

A new approach for inserting repeaters in 3-D interconnects is proposed. The allocation of repeaters along an interplane interconnect is iteratively determined. The proposed approach is compared with two other techniques based on conventional methods used ...

Alignment of defect levels and band edges through hybrid functionals: Effect of screening in the exchange term

Alfredo Pasquarello, Peter Broqvist, Hannu-Pekka Komsa

We investigate how various treatments of exact exchange affect defect charge transition levels and band edges in hybrid functional schemes for a variety of systems. We distinguish the effects of long-range vs short-range exchange and of local vs nonlocal e ...

The role of ion and electron electrostatic turbulence in characterizing stationary particle transport in the core of tokamak plasmas

Olivier Sauter, Emiliano Fable

A general feature of particle transport in the core of tokamak plasmas is that when core particle sources are small, a stationary peaked density profile is provided by a balance of outward diffusion and inward convection, driven by either neoclassical or t ...
