(cont.) to variations in the way functional elements interact with verbal roots. Overall, my work not only contributes to our understanding of how events are syntactically represented, but also explicates interactions at the syntax-semantics interface, clarifying the relationship between surface…

This thesis examines the evolution of Internet based knowledge networks (e-knowledge networks) in the domain of sustainable development. The objective of this thesis is to use an engineering systems approach to understand knowledge networks, identify the barriers to their sustainability…

This report develops a conceptual framework in which to talk about mathematical knowledge. There are several broad categories of mathematical knowledge: results which contain the traditional logical aspects of mathematics; examples which contain illustrative material; and concepts which include formal…

This study investigates an approach of knowledge discovery and data mining in insufficient databases. An application of Computational Taxonomy analysis demonstrates that the approach is effective in such a data mining process. The approach is characterized by the use ot…

The goal of this work involves the developing of an argumentation-based formalism that an agent could use for constructing plans. In this formalism, agents will have certain knowledge about the world, and a set of actions that they will be…

If we are provided a face database with only one example view per person, is it possible to recognize new views of them under a variety of different poses, especially views rotated in depth from the original example view? We…

The use of clocks for timekeeping seems to be a straightforward and almost intuitive routine. Glancing at mechanical clocks designed in Edo period Japan, however, we witness how modern-day intuitions betray our attempts to understand devices created in a culture…

This project investigates how doctoral students make
‘learning leaps’ to recognise and cross conceptual
and skills thresholds in their research and ways in
which they can be best supported to do so. It
responds to current national and international
concerns…
