Cette thèse a pour but d'évaluer l'hétérogénéité crustale et de comprendre son effet sur la propagation des ondes sismiques. Nous étudions l'énergie de la coda de...

Therapeutic embolization is nowadays a first line treatment for haemorrhage, arteriovenous malformation or tumors. Among different embolization agents, non degradable...

In recent years, applications in domains such as telecommunications, network security or large scale sensor networks showed the limits of the traditional...

The assessment of liver fibrosis is an essential source of information for the clinician in the diagnosis, treatment and monitoring of chronic liver disease. Echosens...

A supersolid is an elastic solid which is partly superfluid. Supersolidity which has been experi- mentally observed in 4He in 2004, seems paradoxical and is still...

Many thermodynamic changes occur in reservoir rock when oil is produced. These changes enable scale formation on micrometric rock pores that can block them and...

Une estimation correcte des efforts aux impacts est motivée par le dimensionnement des structures à la rupture sous impact. Le second objectif de ces estimations est...

The main objective of this study is to evaluate the variable thermal and hydric effect, with fissuration effect on the hydraulic behaviour of two concretes. Many...

Optical coherence tomography (OCT) is now an established technique for visualizing the internal morphology of the eye. In the last decade, the aim has been to achieve...

In this physics PHD thesis applied to vegetal physiology we focus on two phenomenons dealing with plants. The capillary ascension of liquids in corners and lodging of...

We study the influence of the VASP protein on dynamics and mechanics of the actin networks that drive cell motility. Our experimental setup is an in vitro bead system...

This study takes place under the guidance of high intensity focused ultrasound therapies (HIFU). The use of ultrasound for guidance allows real time monitoring, but...

Monitoring the evolution of an early age set of parameters on concrete is necessary to predict the early age behaviour of structures. The difficulty lies in the fact...

Les pages qui suivent présentent les travaux que j'ai effectués depuis le début de mes recherches en 1995. Ils ont été menés d'abord au laboratoire d'Analyse Non...
