People with diabetes occupy approximately 18% of all acute inpatient hospital beds in the UK, compared with 6.5% of the general population. For those undergoing surgery, having diabetes is known to be associated with increased harms, however harm is defined. For those undergoing elective surgery, there is a defined patient journey, starting with re...

Tree breeders must almost always address multiple traits. That entails choosing selection methods and weighing up known or assumed economic-worth functions for traits. Classically, selection methods include independent culling levels, sequential culling for traits within generations, culling for different traits in successive generations (tandem se...
Dans un scénario de transition énergétique où la production et les grands réseaux de distribution d’électricité sont remis en cause, le potentiel de production au niveau des écoulements à faible vitesse est important et reste encore peu exploité. Cette thèse étudie un concept novateur d’hydrolienne permettant de répondre en partie à cette problémat...
Fert est une agri-agence française accompagnant des organisations de producteurs dans treize pays. À Madagascar, elle accompagne le Groupe Fifata. Certains des services proposés par les organisations de producteurs de ce groupe ont vécu ce qu’on appelle un changement d'échelle, c’est-à-dire un processus par lequel une structure cherche à préserver ...
Along with new cryptanalysis techniques, the security of block ciphers is always evolving. When designing new block ciphers, we thus need to consider these new techniques during the security analysis. In this thesis, we show how to build some core operations for block ciphers to improve the security against some attacks. We first start by describin...

Caper Spurge (Euphorbia lathyris) is a weed that is non-edible and have no other competitive use. The oil has a high percentage of mono-unsaturation in fatty acid composition hence an excellent non-edible feedstock for biodiesel production. The aim of this work is to model the production of biodiesel from E. lathyris using methanol and NaOH catalys...
Reducing the energy consumption of a cloud system while guaranteeing a given quality of service level is a crucial problem encountered today by cloud providers. We consider an auto-scaling model where virtual machines are turned on and off depending on the queue's occupation (or thresholds). This model represents the variability of allocated resour...
In this thesis, we investigate whether maximizing the coverage of taxis can be beneficial when the goal is to minimize the waiting times of the clients. When dispatching taxis, often only current requests are taken into account and not future ones. We examined how beneficial it can be to take coverage into account. For taxi companies it is importan...
District heating systems (DHS) are considered the best alternative to individual heat boilers as they have higher efficiency and enable the use of sustainable heat sources, like geothermal heat sources or waste heat from industry. Currently, most DHSs are operated by choosing a temperature once every day depending on the weather. This setting is ch...
L’étude de la biomécanique de la locomotion en fauteuil roulant manuel (FRM) a pour objectif de limiter le risque d’apparitions de blessures du membre supérieur, en optimisant la facilité à se déplacer. De nombreuses études ont montré qu’un ajustement des réglages du FRM avait un impact sur la mobilité. Néanmoins, les modèles utilisés dans la litté...
