Lagrangian coherent structures and trajectory similarity: two important tools for scientific visualization
This thesis studies the computation and visualization of Lagrangian coherent structures (LCS), an emerging technique for analyzing time-varying velocity fields (e.g. blood vessels and airflows), and the measure of similarity for trajectories (e.g. hurricane paths). LCS surfaces and trajectory-based …

Accuracy in scientific visualisation
Quite often, accuracy is a neglected issue in scientific visualization. Indeed, in most of the visualizations there are two wrong assumptions: first, that the data visualized is accurate. Second, that the visualization process is exempt from errors. On these basis, the objectives of this thesis are …

A framework for the visualization of multidimensional and multivariate data
High dimensionality is a major challenge for data visualization. Parameter optimization problems require an understanding of the behaviour of an objective function in an n-dimensional space around the optimum - this is multidimensional visualization and is a natural extension of the traditional …
