New time-dependent slip inversion of Slow Slip Events: application to the 2006 Guerrero SSE

Mathilde Edmée Lucette Radiguet de la Bastaie

The 2006 Slow Slip Event in Guerrero, Mexico, is one of the world's largest SSE observed up to now. Thanks to the development of the Guerrero GPS network, the 2006 event was recorded at 15 continuous GPS stations that allowed a detailed study of the surfac ...

Analytic Sensing: Noniterative Retrieval Of Point Sources From Boundary Measurements

Dimitri Nestor Alice Van De Ville, Thierry Blu, Djano Kandaswamy

We consider the problem of locating point sources in the planar domain from overdetermined boundary measurements of solutions of Poisson's equation. In this paper, we propose a novel technique, termed "analytic sensing," which combines the application of G ...

Identity Aware Sensor Networks

Christina Fragouli, Suhas Diggavi, Lorenzo Keller, Mahdi Jafari Siavoshani

In a significant class of sensor-network applications, the identities of the reporting sensors are an essential part of the reported information. For instance, in environmental monitoring, the goal is to reconstruct physical quantities over space and time; ...

The surface Laplacian operator of the potentials on a bounded volume conductor has a unique inverse

In the discussion on the use of the surface Laplacian (SL) of the distribution of bioelectric potentials on the body surface, the question remained open whether a complete specification of the SL of the potential over the surface bounding a volume conducto ...

Cardinal Exponential Splines: Part I—Theory and Filtering Algorithms

Michaël Unser, Thierry Blu

Causal exponentials play a fundamental role in classical system theory. Starting from those elementary building blocks, we propose a complete and self-contained signal processing formulation of exponential splines defined on a uniform grid. We specify the ...

Le management des communautés virtuelles

Olivier Glassey

In the last three decades the management of information technologies has become a major issue in most organizations. In this context, virtual communities (VC), as a means to technologically foster collective social exchanges, are often proposed as viable s ...
