Abstract:

One important issue in mechanism design theory is to model agents’ behaviors under uncertainty. The classical approach assumes that agents hold commonly known probability assessments towards uncertainty, which has been challenged by economists in many fields. My thesis adopts alternative methods to model agents’ behaviors. The new findings contribute to understanding how the mechanism designer can benefit from agents’ uncertainty aversion and how she should respond to the lack of information on agen

Abstract:

A high speed stirring apparatus was constructed for following the kinetics of metal ion extraction by chelating agents. The semi-automated system is capable of measuring reactions with half lives of 20 seconds or more with data being collected every second. Experimental data obtained with the device are superior to those collected by batch shakers, fixed interface cells, falling drop, or other stirring devices. The use of a microporous Teflon membrane phase separator along with the thermodynamic relation, the Gibbs Equation, enabled the measurement of drop sizes in a two phase liquid-liquid di

Abstract:

When solutions of various metal 8-quinolinolates or beta-diketonates in an organic solvent were contacted with an aqueous phase and vigorously stirred to generate a large interfacial area, a reversible decrease in the organic phase concentration of the complex was observed. The magnitude of this decrease varied with interfacial area, solvent, temperature, and the nature and concentration of the complex. Analysis of the phenomenon using the Langmuir isotherm showed that the concentration change may be explained by adsorption of significant quantities of the complexes at the increased liquid-liq

Red blood cell hemolysis in sickle cell disease (SCD) releases free hemoglobin.

People interact with each other through natural language to express feelings, thoughts, intentions, instructions etc. These interactions as a result form relationships. Besides names of relationships like siblings, spouse, friends etc., a number of dimensions (e.g. cooperative vs. competitive, temporary vs. enduring, equal vs. hierarchical etc.) can also be used to capture the underlying properties of interpersonal interactions and relationships. More fine-grained descriptors (e.g. angry, rude, nice, supportive etc.) can also be used to indicate the reasons or social-acts behind the dimension

Brannerite, ideally UTi2O6 is a refractory uranium mineral found in many uranium and rare earth element ore deposits around the world, including many in Australia. As brannerite is refractory, ores containing brannerite require more intense leaching conditions than typical uranium ores. Brannerite is the most common refractory uranium mineral, and the most important uranium ore mineral after uraninite (UO2) and coffinite (U(SiO4)1-x(OH)4x). Several high-brannerite uranium deposits in Australia remain un-developed, despite being discovered as early as the 1950s. The aim of this study was to

Abstract:

At least 200,000 m3 of timber are harvested annually using semi-mechanised harvesting systems (SMS) on the Viphya forest plantations in Malawi. Although these systems have long been used on the Viphya, no investigation on their productivity has so far been reported. The absence of local productivity models created uncertainty about the importance of sitebased factors that influence timber harvesting productivity of these systems on the Viphya. Secondly, there is paucity of information regarding the appropriate timber harvesting systems for production maximisation and cost minimisation. T

Abstract:

This thesis is concerned with the structural estimation of macroeconomic models via Bayesian methods and the economic implications derived from its empirical output. The first chapter provides a general method for estimating structural VAR models. The second chapter applies the method previously developed and provides a measure of the monetary stance of the Federal Reserve for the last forty years. It uses a pool of instruments and taking into account recent practices named Unconventional Monetary Policies. Then it is shown how the monetary transmission mechanism has changed over time, focusin

Etude thermodynamique et cinetique de la corrosion electrochimique dans les melanges hf-mf(m=k ou nh::(4)) du cuivre metal entrant, soit pur, soit sous forme d'alliage (monel) dans la construction des cellules industrielles d'electrolyse. Mise en evidence de la formation d'une couche de fluorure de cuivre passivante. Evaluation de l'epaisseur limite de la couche. Etablissement de l'influence de la densite de courant sur le caractere passivant de la couche formee. Proposition d'un mecanisme de corrosion du cuivre

Abstract:

Aujourd'hui, la plupart des entreprises occidentales se sont dotées d'un système de management par projets, caractérisant l'évolution d'une économie de masse à une économie de variété et de réactivité. Il s'ensuit chez les constructeurs une délégation de plus en plus importante aux équipementiers, des responsabilités liées à la conception des composants. Cette tendance nous a conduits aux 3 hypothèses suivantes : (1) l'équipementier doit acquérir la compétence design local dans les années à venir, (2) il doit donc se positionner rapidement en se préparant à participer au processus design à un

Abstract:

Ce travail de thèse porte sur l'extraction et la caractérisation mécanique des fibres de canne à sucre. A partir de la bagasse de canne à sucre, résidu fibreux de l'industrie sucrière, des techniques d'extractions sont mises en place afin d'extraire des fibres techniques, dont l'analyse des propriétés chimiques et physico-mécaniques définira par la suite, les domaines d'application textile possibles. Les fibres de canne obtenues ont d'abord été étudiées d'un point de vue physique et morphologique, à partir de mesures et d'observations de leurs sections et de leurs profils. Ainsi, l'analyse de
