An optimal first-order solver for the TV-$L_1$ optical flow problem

Pierre Vandergheynst, Gilles Puy, Emmanuel D'Angelo

In this study, we address the problem of computing efficiently a dense optical flow between two images under a total variation (TV) regularization and an

Robust Controller Design by Convex Optimization based on Finite Frequency Samples of Spectral Models

Alireza Karimi, Roland Longchamp, Gorka Galdos Sanz de Galdeano

Some frequency-domain controller design problems are solved using a finite number of frequency samples. Consequently, the performance and stability conditions are not guaranteed for the frequencies between the frequency samples. In this paper, all possible ...

An Automated, yet Interactive and Portable DB designer

Anastasia Ailamaki, Ioannis Alagiannis, Debabrata Dash

Tuning tools attempt to configure a database to achieve optimal performance for a given workload. Selecting an optimal set of physical structures is computationally hard since it involves searching a vast space of possible configurations. Commercial DBMSs ...

Processor Speed Control with Thermal Constraints

Giovanni De Micheli, David Atienza Alonso, Srinivasan Murali

We consider the problem of adjusting speeds of multiple computer processors, sharing the same thermal environment, such as a chip or multichip package. We assume that the speed of each processor (and associated variables such as power supply voltage) can b ...

Compressed sensing imaging techniques for radio interferometry

Pierre Vandergheynst, Yves Wiaux, Gilles Puy, Laurent Jacques

Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actually suffice for accurate reconstruction of sparse or compressible signals. We ...

GaN-based embedded 2D photonic crystal LEDs: Numerical optimization and device characterization

Elison de Nazareth Matioli

We present the numerical optimization of GaN-based embedded 2D-Photonic Crystal (PhC) LEDs based on a full 3D scattering matrix model pointing out the importance of a proper vertical design in embedded PhC structures. The growth of such structures followin ...

Compressed sensing imaging techniques for aperture synthesis by radio interferometry

Pierre Vandergheynst, Yves Wiaux, Gilles Puy, Laurent Jacques

Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actually suffice for accurate reconstruction of the signals. We propose new generi ...

Numerical methods and models relevant to transportation applications

Michaël Clément Louis Ghislain Thémans

In this thesis, we focus on standard classes of problems in numerical optimization: unconstrained nonlinear optimization as well as systems of nonlinear equations. More precisely, we consider two types of unconstrained nonlinear optimization problems. On t ...
