Optimal control in heterogeneous domain decomposition methods

Some new domain decomposition methods (DDM) based on optimal control approach are introduced for the coupling of first- and second-order equations on overlapping subdomains. Several cost functionals and control functions are proposed. Uniqueness and existe ...

Concept expansion using semantic fisheye views

Pearl Pu Faltings, Vincent Jean Fabrice Schickel

Exploratory search over a collection often requires users to iteratively apply a variety of strategies, such as searching for more general or more specific concepts in reaction to the information they encounter. Rich semantic models, such as WordNet, are p ...

The M-Term Pursuit for Image Representation and Progressive Compression

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

This paper introduces a sparse signal representation algorithm in redundant dictionaries, called the M-Term Pursuit (MTP), with an application to image representation and scalable coding. The MTP algorithm belongs to the framework of the matching pursuit ( ...

Analysis of dynamic traffic equilibrium with departure time choice

We present and analyse a model of the combined choice of departure time and route in a congested road network. Using the property of equilibrium solutions that for each origin-destination pair the total cost associated with travel is identical for all trav ...

Optimal femoral head contour segmentation in CT images using dynamic programming

Charles Baur, Gaëtan Marti

We present a new contour segmentation method for femoral head detection in CT images. The principal idea underlying our approach is to represent the contour using active rays. Each ray has internal energy (continuity and smoothness constraints), as well as ...

Polyharmonic Smoothing Splines for Multi-Dimensional Signals with 1 ⁄ $ ||ω|| ^{ \tau } $ -Like Spectra

Michaël Unser, Dimitri Nestor Alice Van De Ville

Motivated by the fractal-like behavior of natural images, we propose a new smoothing technique that uses a regularization functional which is a fractional iterate of the Laplacian. This type of functional has previously been introduced by Duchon in the con ...

Route choice relevance in complex urban network micro- simulation models

André-Gilles Dumont, Emmanuel Bert

In dynamic models, like microsimulation, dynamic traffic assignment is based on the use of traffic conditions measured during the simulation process in order to keep o sort of equilibrium between demand and supply. Route choices are consequently done by kn ...

Historical based traffic assignment in microsimulation for advanced traveller information systems assessments

André-Gilles Dumont, Emmanuel Bert

In dynamic models, like microsimulation, dynamic traffic assignment is based on the use of traffic conditions measured during the simulation process in order to keep o sort of equilibrium between demand and supply. Route choices are consequently done by kn ...

Explicit infiltration equations and the Lambert W-function

David Andrew Barry

The Green and Ampt infiltration formula, as well as the Talsma and Parlange formula, are two-parameter equations that are both expressible in terms of Lambert W-functions. These representations are used to derive explicit, simple and accurate approximation ...

How to repair CSK using small perturbation control - Case study and performance analysis

Thomas Schimming, Slobodan Kozic, Kumiko Oshima

In this paper we study coded modulation schemes based on iterated chaotic maps. In particular, we consider

CSK

-like systems in which a chaotic map is switched depending on the payload. We show how small perturbation control can substantially improve the ...
