In response to infection by pathogens, plants deploy various and complex defense mechanisms. Resistance can be expressed locally and systemically, depending on the nature of the inducing stimulus. For instance, after infection by a necrotizing pathogen, resistance develops throughout the plants, in tissues distant from the initial site of infection. This form of resistance, called systemic...

Tourism and culture are strongly intertwined. People can experience culture before, during and after their journey, both in the offline and in the online world. Arguably, the internet is among the main sources of inspiration and information retrieval for tourists, who navigate social media and websites to know more about the destination, its products and services. Following the developments in...

Understanding the performance of software is complicated. For several performance metrics, in addition to the algorithmic complexity, one must also consider the dynamics of running a program within different combinations of hardware and software environments. Such dynamical aspects are not visible from the code alone, and any kind of static analysis falls short. For example, in reality, the...

After injury to the adult central nervous system (CNS), permanent deficits remain to a large part due to limited cell renewal, axonal regeneration and reestablishment of functional connectivity. Evidence indicate that the lack of axonal regeneration is partly due to the myelin-associated inhibitory factor Nogo-A. A therapeutical strategy to overcome this inhibition is to prevent the neurite...

This thesis is a collection of properties and applications of linear barycentric rational interpolation, mainly with the weights presented by Floater and Hormann in 2007. We are motivated by the counterintuitive and provable impossibility of constructing from equispaced data an approximation scheme that converges very rapidly to the approximated function and is simultaneously computationally...

Knowledge and information make our lives easier and more enjoyable. In this thesis we use techniques and concepts from statistical physics and probability theory to explore several models of complex systems where information plays a prominent role. When building these models we tried to capture main aspects of real systems but also to keep the models simple and analytically solvable. We begin the...

Nous présentons dans cette thèse une approche d’analyse uniforme pour la reconnaissance de la structure physique des documents à contenu varié. Après une introduction à la problématique traitée dans cette thèse, nous présentons une synthèse des traitements usuels dans le domaine de la reconnaissance des documents. Dans cette synthèse, nous présentons aussi les structures usuelles...
