This work is devoted to the study of the phenomena expansion and collapse for difference polymer models. We investigate the 1 + 1 dimensional self-interacting and partially directed self-avoiding walk, usually referred to by the acronym IPDSAW. The IPDSAW is known to undergo a extended-collapsed transition at a critical point _c. We develop a new method to study the partition function of this model, from which we derive a variational formula for the free energy. This variational formula allows us to prove the existence of the collapse transition and to identify the critical point in a simple way. We provide the precise asymptotic of the free energy close to criticality. We then establish some path properties of the random walk inside the collapsed phase (_ > _c). Finally, we study the IPDSAW subject to a force. We show how to detect the presence of a re-entrant phenomenon without fully solving the model

Analyse statistique d'évaluations sensorielles au cours du temps by
Stéphanie Ledauphin(
Book
)
2 editions published in 2007 in French and held by 2 WorldCat member libraries worldwide
Sensory analysis of food products is most often based on scores given by panellists according to a list of descriptors that characterize the products. A statistical method for analyzing sensory profiling data obtained by means of fixed vocabulary is discussed. It consists in a procedure for weighted averaging the data sets associated with the assessors taking account of the extent to which these assessors agree with the general point of view. The method of analysis also provides an overall index of the performance of the panel and performance indices associated with the various assessors. In conventional sensory profiling, the evaluation focuses on an overall assessment and does not reflect the dynamic process of the sensory perception in the course of time. This is the reason why Time Intensity (TI) curves are becoming more and more popular notwithstanding the poor performance of the assessors and the tricky statistical issues these curves pose. In particular, a common feature of the TI curves is that each assessor tends to generate a characteristic shape, called 'subject signature'. The functional approach adopted herein is specifically based on the identification and the correction of the 'signature' effect of the assessors by adjusting the individual curves. The cornerstones of the method are the use of the projection upon a B-spline basis and alignment procedures. Other sensory analysis over time exist such as the study of the decay of organoleptic perception of the products. We propose to use Markov chains and Hidden Markov chains to model this decay and focus on the graphical comparison of the evolution of several products

Perturbations de la transition d'adsorption dans des modèles de polymères by
Alexandre Legrand(
)
1 edition published in 2021 in English and held by 1 WorldCat member library worldwide
Cette thèse étudie deux modèles de polymères, chacun présentant un phénomène de transition de phase d'adsorption. Le premier modèle concerne un polymère interagissant avec son solvant et avec un mur dur. Si l'affinité chimique du polymère avec le solvant est suffisamment faible, le polymère s'effondre sur lui-même pour former un globule compact. Dans ce régime, nous étudions l'interaction entre le globule et le mur, et explicitons un phénomène de transition de surface. Nous donnons également un équivalent asymptotique exact de la fonction de partition du polymère effondré dans le cas où il n'y a pas de mur. Le second est une modélisation du phénomène de dénaturation des brins d'ADN, ou plus généralement de deux polymères pouvant s'accrocher entre eux. Nous étudions l'effet que des inhomogénéités dans la composition des polymères ont sur la transition de dénaturation, en terme de (non)-pertinence d'un champ de désordre fortement corrélé. Nous étudions également la limite d'échelle de désordre intermédiaire de ce modèle

On the Lyapunov exponent of random transfer matrices and on pinning models with constraints by
Benjamin Havret(
)
1 edition published in 2019 in English and held by 1 WorldCat member library worldwide
This work is made of two independent parts. The first (Chapters 1 and 2) is devoted to the study of the Lyapunov exponent of a product of random transfer matrices. This Lyapunov exponent appears repeatedly in the statistical mechanics literature, notably in the analysis of the Ising model in some special disordered environments. The focus is on a singular behaviour that has been pointed out in the physical literature: we provide a mathematical analysis of this singularity. In the second part (Chapters 3, 4 and 5) we consider a variation of the Poland-Scheraga model for DNA denaturation. This variation aims at modeling the case of circular DNA. We provide a complete analysis of the homogeneous model, including free energy regularity and critical behaviour, as well as path properties. We also tackle the disordered case, for which we prove relevance of disorder both for the free energy and the trajectories of the system
