Abstract:

The development of spatial structure and form on vertebrate skin is a complex and poorly understood phenomenon. We consider here a new mechanochemical tissue interaction model for generating vertebrate skin patterns. Tissue interaction, which plays a crucial role in vertebrate skin morphogenesis, is modelled by reacting and diffusing signal morphogens. The model consists of seven coupled partial differential equations, one each for dermal and epidermal cell densities, four for the signal morphogen concentrations and one for describing epithelial mechanics. Because of its complexity, we reduce

Abstract:

The main aim of the thesis is to explore the interaction between pattern and process in vegetation ecology using a variety of mathematical and statistical methods. Of particular interest is what information about the dynamics of the underlying system can be gained through a single spatial snapshot, such as an aerial photograph or satellite image. The hypotheses are related to seagrass ecology, whose growth is primarily clonal and broadly exists as a monoculture and thus makes it an ideal candidate to study these interactions. The thesis broadly concerns two forms of spatial pattern and the und

Abstract:

The field of stochastic growth encompasses various different processes which are ubiquitously seen across the physical world. In many systems, stochasticity appears quite naturally, where inherent randomness provides the right setting for the tone of motion and interaction, whose symphony leads to the surprising emergence of interesting patterns and structure. Although on the microscopic scale one can be overwhelmed by the randomness arising from the fluctuating interactions between components, on the macroscopic scale, however, one is mesmerized by the emergence of mathematical beauty and sym

Abstract:

This thesis studies the gradient system that forms spatial patterns such that the minimum distances of pairs among various points are maximized in the end. As this problem innately involves singularity issues, an extended system of the gradient system is proposed. Motivated by the spatial pattern suggested by a numerical example, this extended system is applied to a three-point problem and then to a two-point problem in a quotient space of R2 modulo a lattice.

Abstract:

Structure, in its many forms, is a central theme in theoretical population ecology. At a mathematical level, it arises as nonuniformities in the topology of nonlinear dynamical systems. I investigate a mechanism wherein a chaotic time series can have episodes of nearly periodic dynamics interspersed with more 'typical' irregular dynamics. This phenomenon frequently appears in biological models, and may explain patterns of alternating biennial and irregular dynamics in measles epidemics. I investigate the interaction between spatial structure and density-dependent population regulation with a s

Chapter 2 deals with a linear city model Ã la Hotelling where the two firms share linear transport costs with their customers. Mill pricing and uniform delivery pricing are special limiting cases. We characterize the conditions for the existence of a pure strategy equilibrium in the two-stage location-price game. These enable us to identify the causes for non-existence in the two limiting cases. We solve for the equilibrium of a location game between the duopolists with an exogenously given price. When the two firms are constrained to locate at the same central spot, we show the nonexistence

Abstract:

The recent evidence concerning the nature of cognitive development in Down Syndrome (DS) suggests that it is different than normal development. The neuropathology seen in DS implicates a prenatal interruption of normal neural development as a possible basis for these differences. Since the hippocampal formation (HF) undergoes extensive postnatal maturation and is found to be abnormal in DS, it is proposed that cognitive deficits associated with DS would be most evident in tasks requiring hippocampal function. The performance of DS children at 16-18 months and 28-30 months of age was compared t

Abstract:

Cette thèse traite du contrôle du vol en formation de vaisseaux spatiaux. Le vol en formation permet de réaliser de nouveaux scénarios de missions. De par la diversité des applications envisageables, les travaux sont divisés en deux parties. Dans la première partie, restreinte au contrôle des centres de masse des vaisseaux, une approche est proposée pour modéliser les orbites relatives entre deux satellites en orbite terrestre, tenant compte de l'aplatissement de la Terre. Fondée sur le scénario d‘une mission en orbite de transfert géostationnaire, la problématique d‘une dynamique à paramètre

Abstract:

The spatial arrangements of artifacts and features within archaeological sites have often been used to isolate activity areas and draw inferences about site function. This approach assumes that objects found in close proximity were used for the same task, and that artifacts are usually discarded where they were used. However, the location of artifact abandonment often has more to do with patterns of discard and use/reuse of the site throughout time than with the function or location of activities. This dissertation uses a comparative framework to address how the observed spatial structure of M

Abstract:

Pattern formation in ecological systems refers to a nonuniform distribution of animal and plant species across a landscape. Pattern formation can be observed in many aquatic and terrestrial systems and can provide important insights into their dynamics and ability to cope with environmental changes. In this dissertation, we focus on pattern formation in tidal marshes and oyster reefs, two important habitats that provide a number of essential ecosystem services. Both of these systems have also experienced dramatic losses, prompting much research to investigate their dynamics as and viable resto

Abstract:

Dans la Formation de Shungura l’apparition du comportement de taille de la pierre coïncide avec l’apparition de l’Oldowayen ancien et se concentre sur un laps de temps relativement resserré (Membre F et partie inférieure du Membre G ; 2,32 Ma à 2 Ma), bien que les hominidés fossiles soient présents tout au long de la séquence (3,6 à 1 Ma). Afin de questionner les interrelations et l’évolution entre les occupations humaines de l’Oldowayen ancien et les facteurs environnementaux, une approche multi-scalaire a été développée. Elle permet d’intégrer les très nombreuses données archéologiques (une
