Signal, Image and Video Processing, 2021
The quaternion offset linear canonical transform (QOLCT) has gained much popularity in recent years because of its applications in many areas, including image and signal processing. At the same time, the applications of Wigner–Ville distribution (WVD) in

Moving Ground Target Detection With Seismic Signal Using Smooth Pseudo Wigner–Ville Distribution
IEEE Transactions on Instrumentation and Measurement, 2020The main challenging task in moving ground target detection with seismic signals is the extraction of robust feature vectors for accurate localization of a seismic event.

Multichannel maximum-entropy method for the Wigner-Ville distribution
, 2020The Wigner-Ville distribution is a powerful technique for the time-frequency spectral analysis of nonstationary seismic data. However, the Wigner-Ville distribution suffers from the cross-term interference between different wave components in the seismic

Ville numérique, ville événement
Flux, 2010Résumé Les conséquences de la révolution numérique sur la ville et sa planification sont encore loin d’être claires. Après avoir discuté et critiqué un certain nombre d’hypothèses qui ont pu être avancées dans un passé récent concernant l’impact urbain des technologies de l’information et de la communication, comme la dématérialisation des flux ou ...

De l’intérêt pour la nature en ville
Revue d'Économie Régionale & Urbaine, 2019Aujourd’hui, une nouvelle relation semble se tisser entre la ville et la nature. Cet article identifie les elements sur lesquels repose ce nouvel interet pour la nature en ville.

Villes ouvertes, villes accueillantes
2020Comment répondre aux défis posés aux villes par les migrations ? Quelles solutions architecturales et urbaines mettre en place quand les manières actuelles de fabriquer la ville ne savent manifestement pas résoudre les problématiques de l’accueil pour les populations sans domicile ? Les habitants, la société civile et les élus locaux n’ont pas de prise
