Abstract:

Plusieurs invariants sont associés à la classe de déformation d'une courbe algébrique réelle lisse à dans une surface algébrique réelle x : son schéma réel, dont l'étude systématique a été proposée par D. Hilbert dans son 16ème problème dans le cas ou x = cp 2, sa classe d'isotopie équivariante dans x, ou encore lorsque la courbe est séparante, son schéma complexe ainsi que les classes d'homologie dans h 2(x,rx;z) réalisées par les composantes de a ra. La première partie de cette thèse établit un lien entre ces deux derniers invariants, en introduisant une forme définie sur h 2(x ; z/lz) a val

Abstract:

La première partie du seizième problème de Hilbert traite de la topologie des courbes algébriques réelles régulières dans le plan projectif. Il est bien connu que bon nombre des propriétés topologiques satisfaites par de telles courbes sont également vraies pour la classe plus large des courbes flexibles, introduites par O. Viro en 1984. Le but de cette thèse est d'approfondir les origines topologiques des restrictions sur les courbes réelles, en lien avec le seizième problème de Hilbert. Nous ajoutons une condition naturelle à la définition de courbe flexible, à savoir qu'elles doivent inters

Abstract:

The study aimed at researching the role of materials in flexible learning teacher education courses, specifically looking at the Eastern Cape Teacher Course as a case study. The research aimed at exploring how courses and materials were developed, selected, used and adapted or redeveloped so as to support the course orientation and the intended outcomes. I did this with the hope that my research might inform the process of improving the role of course materials in flexible learning teacher education courses. I did a naturalistic enquiry within which I interviewed 39 participants (teachers and

Abstract:

L'expérience des changes flexibles qui a duré plus de quinze ans n'a guère permis de vérifier les résultats avancés par le modèle standard d'inspiration keynésienne. Le moins que l'on puisse dire, argumente-t-on, ces résultats s'inspirent d'une analyse incomplète. Les lacunes de ce modèle sont comblés par une reformulation de certaines hypothèses d'une manière plus adéquate à la situation observée. Cette reformulation conduit à l'explication des phénomènes tels le surajustement (ou sous-ajustement) du taux de change, le cercle vicieux (ou vertueux) et les bulles spéculatives rationnelles. Ces

The aim of the dissertation is based on the properties of flexible road pavement structures to develop a mathematical models for predicting the performance of wearing courses used in the pavements of the main roads. The main tasks of the dissertation are as follows: to analyze the main factors influencing the service indices of asphalt concrete pavements and to determine their reasons; to investigate the quality of materials and mixtures used in pavement structural layers of the main roads; to determine the interaction between asphalt concrete pavement composition and the quality indices of mi

Abstract:

Collaborative Learning is the pedagogical approach that considers social interactions as key means to trigger rich learning processes. Collaborative Learning Flow Patterns define best practices to orchestrate collaborative learning activity flow mechanisms (i.e., group formation, roles or resources allocation, phase change). Flow patterns have been experimented and evaluated as effective in small scale settings for decades. Directly applying these pedagogical methods to large learning scenarios is challenging due to the burden that scale represents in the orchestration load or the difficulty o

Abstract:

This study examines the use of concrete waste by-products as a new source of road construction material in Western Australia (WA). The amount of construction waste in Western Australia increases annually, whilst natural rock aggregate is in shortage.This research focuses on whether recycled concrete, derived from various sources such as by-products from the processes of manufacturing ready-mixed concrete and waste from construction and demolition (C&D), is a viable option for use as a base and sub-base course material in road building in WA.A series of laboratory tests were conducted to determ

Abstract:

The purpose of this study was to improve flexible base course performance within the state of Texas while reducing TxDOT’s testing burden. The focus of this study was to revise the current specification with the intent of providing a “performance related” specification while optimizing sample sizes and testing frequencies based on material variability. A literature review yielded information on base course variability within and outside the state of Texas, and on what tests other states, and Canada, are currently using to characterize flexible base performance.
