The new 5G’s wireless networks have started to be deployed all around the world. With them, a large spectrum of services are about to emerge, resulting in new stringent requirements so that 5G targets performances exceed that of 4G by a factor of 10. The services are enhanced mobile broadband (eMBB), ultra reliable and low-latency communication (uR...
Nous ne comprenons pas encore complètement le rôle que les caractéristiques physiques des surfacesexercent sur la réponse hydro-sédimentaire des bassins versants aux précipitations. L’objectif de ce travailde thèse est donc de comprendre de quelle manière les flux hydro-sédimentaires, générés par le climat, sontmodulés par les caractéristiques des ...
A new avenue for handwriting analysis to help diagnose dysgraphia in children, using dynamic oscillatory models, has been investigated. The Parsimonious Oscillatory Model of Handwriting (POMH) is shown to be able to reconstruct the handwriting trace provided that it is sufficiently smooth. For children suffering from dysgraphia, POMH leads to great...
Cette thèse décrit la conception, le développement et l'évaluation de Mono-Replay, une application permettant d'interpréter, à l'aide d'un dispositif de contrôle gestuel, une œuvre enregistrée sur un média (disque vinyle, bande magnétique, fichier audionumérique, fichier midi). Le musicien peut ainsi proposer un parcours de lecture différent de cel...
This dissertation presents a class of representations of spatial point processes. Inspired from the success of wavelet methods in signal processing, these descriptors rely on the convolution of a point process with a family of wavelet filters. From these convolutions are built sets of statistical descriptors of stationary point process, by applying...
In the framework of the acquisition chain and devices built by i2S, the objective of this PhD is to provide efficient algorithms able to merge different acquired images corresponding to slight spatial translational displacements to get a wider super-resolved image. Consequently, this PhD takes place within the general subject of super-resolution. I...
The analysis of Volatile Organic Compounds (VOCs) in exhaled breath is a promising non-invasive approach in medicine for early diagnosis, phenotyping, disease and treatment monitoring and large-scale screening. Proton Transfer Reaction Time-Of-Flight Mass Spectrometry (PTR-TOF-MS) is of major interest for the real time analysis of VOCs and the disc...
Quantum key distribution offers the possibility of cryptography whose security is demonstrated by the laws of quantum physics. The first commercial systems of this technology are now available. This thesis focuses on continuous variable protocols, whose practical implementation is close to modern digital transmission techniques over optical fibers....
We are constantly surrounded by sounds that we continuously exploit to adapt our actions to situations we are facing. Some of the sounds like speech can have a particular structure from which we can infer some information, explicit or not. This is one reason why speech is possibly that is the most intuitive way to communicate between humans. Within...
Autonomous driving requires a detailed understanding of complex driving scenes. The redundancy and complementarity of the vehicle’s sensors provide an accurate and robust comprehension of the environment, thereby increasing the level of performance and safety. This thesis focuses the on automotive RADAR, which is a low-cost active sensor measuring ...
