Prédiction spatiale en présence d'erreurs substitutives et modélisation par drap stable
Author(s) :
Fournier, Baptiste
Description :
In geostatistics, the presence of outlying data is more the rule than the exception. Moreover, the statistical analysis of data contaminated by outliers requires caution, particularly when a spatial dependence exists. In order to take into account these possible outliers during the adjustment of the...

Study of cementitious materials using transmission electron microscopy
Author(s) :
Mathur, Prakash Chandra
Description :
An important mode of hydration of Ordinary Portland cement (OPC) is via the formation of a shell of hydration products around cement grains. It has been shown so far that shells form not only in OPC but also around C3A grains in a mixture of alite, C3A and CS and in more restricted form in pure alit...

Characterisation of high-burnup LWR fuel rods through gamma tomography
Author(s) :
Caruso, Stefano
Description :
Current fuel management strategies for light water reactors (LWRs), in countries with high back-end costs, progressively extend the discharge burnup at the expense of increasing the 235U enrichment of the fresh UO2 fuel loaded. In this perspective, standard non-destructive assay (NDA) techniques, wh...

Plasma production and transport in a simple magnetised toroidal plasma
Author(s) :
Podestà, Mario
Description :
This Thesis addresses questions related to transport phenomena and the plasma production mechanisms by injection of microwaves in the electron-cyclotron frequency range in the simple magnetised toroidal plasma TORPEX. The second subject is investigated in detail in Part II. The mechanisms of the int...

Improvement of an urban turbulence parametrization for meteorological operational forecast and air quality modeling
Author(s) :
Muller, Clive
Description :
During the last century, urban pollution has increased with the growth of cities. Urban air quality has become a high priority as it is directly linked to concerns such as human exposure and health. The present work is dedicated to urban air quality modeling with focus on urban meteorology. The main...

Spectroscopy and kinetic studies of electron-hole recombination in CdSe nanoparticles: effect of size, shape, and lattice structure
Author(s) :
Al Salman, Awos
Description :
This thesis presents an experimental study of the energy and time-resolved optical response of chemically prepared CdSe nanoparticles with different sizes, shapes (dots, rods, and tetrapods), and lattice structures (wurtzite and zinc blende). The first part of the thesis concerns a model system: sph...

Understanding the origins and fate of air pollution in Bogota, Colombia
Author(s) :
Zarate, Erika
Description :
Bogota has more than 8 million inhabitants and is the 5th biggest urban agglomeration in Latin America. It has more than one million vehicles and a large number of small industries. High levels of air pollutants are thus detected. The purpose of this work consists in applying air quality modelling t...

The influences of location awareness on computer-supported collaboration
Author(s) :
Nova, Nicolas
Description :
"Where are you?". This recurring question when opening a mobile conversation attests the importance of spatialisation in social interactions. More and more applications support mutual location-awareness: they enable members of a group to locate their partners both in the physical environments and vi...

Design of amphiphilic nanocapsules based on hyperbranched star-block copolymers for the encapsulation and the controlled release of olfactory compounds
Author(s) :
Ternat, Céline
Description :
Effective encapsulation of small, volatile, weakly water-soluble molecules such as flavors and fragrances is necessary to protect them from degradation, to increase their lifetime, and to improve their water dispersion and fixation depending on the substrate of interest. The aim of this project has ...
