In this dissertation we study the electromagnetic properties of planar waveguides
with non-magnetic strongly anisotropic dielectric cores. We develop an analytical
description of the mode propagation in these systems and show that the index
of...

This thesis addresses the problem of learning dynamic Bayesian network
(DBN) models to support reinforcement learning. It focuses on
learning regression tree models of the
conditional probability distributions of the DBNs. Existing
algorithms...

The regulation of behavior is a major issue in early childhood development, with
important implications for children’s adaptive and maladaptive developmental outcomes.
Emerging research suggests that the degree of successful self-regulation...

Maintaining genome integrity is essential for an organism, as mutation
accumulation can lead to cancer, reduced fitness, and heritable diseases in offspring.
Therefore the study of mutations, how they are induced, and how they are prevented is...

This work focuses on the generation and collection of four specific
radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These
nuclides are created by fissioning a highly enriched uranium sample using a
thermal neutron source from...
