This thesis investigates the choice behaviour of first year undergraduate students through proposing and testing a conceptual model. The psychological constructs of personal values, motivation, selection criteria, demographic and socioeconomic factors introduced as underlying drivers provide invaluable insight into the pathways of influence and relationships between student types and their preference towards a particular degree program at a particular university.

Two major areas of the scorecard development process were identified as having much capacity for improving credit scoring models. These are the application of 1) better classifiers and 2) variable selection techniques. However, the application of an artificial immune system for developing scorecards as well as the use of other variable selection techniques, other than stepwise regression, in credit scoring are quite limited as indicated by the scarcity of published materials in these two areas in the current literature.

With a view of providing investors with a better understanding of the risk and return relationship in the A-share market over the past decade, this thesis adapts several empirical models to the circumstances in China and conducts four empirical analyses. The analysis is undertaken employing the returns on the Chinese A-share market, the Chinese B-share market and the Hong Kong H-share market together with a series of developed stock markets.

A Bayesian approach with frequentist validity has been developed to support inferences derived from a BLevel A^ in vivo-in vitro correlation (IVIVC). Irrespective of whether the in vivo data reflect in vivo dissolution or absorption, the IVIVC is typically assessed using a linear regression model. Confidence intervals are generally used to describe the uncertainty around the model. While the confidence intervals can describe population-level variability, it does not address the individual-level variability.

Objectives of thesis: Study on phenol treatment in water by ozonation process combined with catalysts. An empirical kinetic model and one quadratic regression equations were built based on experimental data for destroying phenol by heterogeneous catalytic ozonation process with response variables (initial pH, ozone concentration, catalyst concentration and reaction time). Application of phenol treatment in coking wastewater.

Apart from trying to shed sufficient light on the dominant capital structure in South Africa, this study attempts to answer the question of: what is the role of capital structure in firm valuation? In addition, the role of other market and economic variables like taxation will be assessed using a regression model and data drawn from financial markets.

(BQ) In this paper, working current, working voltage, oil pressure, spark gap Pulse On Time and Pulse Off Time on Material Removal Rate (MRR) and Surface Finish (Ra) has been studied. Empirical models for MRR and Ra have been developed by conducting a designed experiment based on the Grey Relational Analysis. Genetic Algorithm (GA) based multi-objective optimization for maximization of MRR and minimization of Ra has been done by using the developed empirical models. Optimization results have been used for identifying the machining conditions.
