1. Development and Evaluation of Nonparametric Mixed Effects Models
Abstract : A nonparametric population approach is now accessible to a more comprehensive network of modelers given its recent implementation into the popular NONMEM application, previously limited in scope by standard parametric approaches for the analysis of pharmacokinetic and pharmacodynamic data. The aim of this thesis was to assess the relative merits and downsides of nonparametric models in a nonlinear mixed effects framework in comparison with a set of parametric models developed in NONMEM based on real datasets and when applied to simple experimental settings, and to develop new diagnostic tools adapted to nonparametric models.

2. A data-driven decision support system for coherency of experts’ judgment in complex classification problems : The case of food security as a UN sustainable development goal
Abstract : Everyday humans need to make individual or collective decisions. Often the decisions aim at achieving multiple goals (thus involving multiple criteria) and rely on the decision maker(s)’ intuition, internal data, as well as external sources of data. READ MORE

3. Design of a Total-Reflection X-Ray Fluorescence Spectrometer and Application to Periphyton Communities
Abstract : The work presented in this thesis deals with the use of total-reflection X-ray fluorescence (TXRF) spectrometry for trace element analysis of periphyton. A TXRF spectrometer was designed and its performance was evaluated with a plankton reference material. For 12 .my. READ MORE

4. Preference cloud theory : modelling imprecise preferences and a new theory for decision under risk
Abstract : This study presents Preference Cloud Theory, a two-step model of decision making under risk. It also includes an experimental study on valuation gap which provides supporting results for the new theory. READ MORE

5. Bilinear optimization in computational decision analysis
Abstract : In real-life decision analysis, significant recognition has been given to theunrealistic expectation of numerically precise information. Many modernapproaches attempting to handle imprecision have focused more on representationand less on evaluation. READ MORE
