The knowledge of spatial variability soil properties is useful in the rational use of inputs, as in the site specific application of lime and fertilizer. The objective of this work was to map and evaluate the spatial variability of the…

It has been proposed that forms of dialogue (Keegan, 1993) are differentially related to subject knowledge possessed by the student and the roles that teachers and students play within those dialogues. A reading of the socio-constructivist literature suggests that maximal…

This thesis proposes a knowledge based expert system tool that can be used as an on- line controller for the charging/discharging of an energy storage system in a wind-diesel microgrid. The wind-diesel microgrid is modelled, and a typical energy storage…

In reasoning about multi-agent systems, it is important to look beyond the realm of propositional logic and to reason about the knowledge of agents within the system, as what they know about the environment will affect how they behave. A…

Interest in curriculum is often divided between the work of curriculum theorists on one end and the manifestation of curriculum in the classroom on the other. Researchers are drawn to the study of both of these groups, but a third…

Semantic background knowledge is crucial for many intelligent applications. A classical way to represent such knowledge is through semantic networks. Wikipedia's hyperlink graph can be considered a primitive semantic network, since the links it contains usually correspond to semantic relationships…

Reinforcement Learning is a branch of Artificial Intelligence addressing the problem of single-agent autonomous sequential decision making. It proposes computational models which do not rely on the complete knowledge of the dynamics of stochastic environments. Options are a formalism used…

This thesis investigates possible origins of the distinction between consonant and dissonant auditory events and how persons with and without formal musical training judge the distinction. Two studies comprising six experiments used behavioral methods to explore perceptual and cognitive differences…

In-silico methods used to aid the development of therapeutic drugs have gained utility in the recent past and continue to grow in importance. Small molecule drugs for the use in the treatment of type 2 diabetes were designed using computational…

A new ethical medical dilemma concerns the use of hormone-blockers or medications that put puberty on hold in the care of transgender/transsexual (TG/TS) adolescents. These medications are taken until she is old enough to legally consent to cross-sex hormones. Such…
