Application of optical and infrared remote sensing to the retrieval of selected land and sea features
(The University of Waikato, 2001)This thesis discusses two main areas of remote sensing research and thus is divided into two parts. The first part deals with novel methods for sea surface temperature (SST) retrieval using measurements of the Advanced ... -
Investigating the dynamics of a population of spiking neurons across spatial scales
(The University of Waikato, 2021)Mean-field models describe bulk neural activity in terms of population-average action potential (spike) rates, but do not attempt to address the variations in the firing activity of individual neurons and the interactions ... -
Predicting and identifying signs of criticality near neuronal phase transition
(The University of Waikato, 2020)This thesis examines the critical transitions between distinct neural states associated with the transition to neuron spiking and with the induction of anaesthesia. First, mathematical and electronic models of a single ... -
Satellite remote sensing for improvement of groundwater characterisation
(University of Waikato, 2017)Groundwater, the water stored in the subsurface, plays an essential role in water provision for domestic, industrial and agricultural use. Groundwater is also vital for ecology and environment, since it provides base flow ... -
Dynamics and precursor signs for phase transitions in neural systems
(University of Waikato, 2014)This thesis investigates neural state transitions associated with sleep, seizure and anaesthesia. The aim is to address the question: How does a brain traverse the critical threshold between distinct cortical states, both ... -
A Population Model of the Thalamus and its Wave Interactions with the Cortex
(University of Waikato, 2014)In this thesis we construct a population model of the thalamus based on the mean-field cortex developed by Steyn-Ross et al. and Liley et al. We allow interactions between the thalamus and cortex via damped wave equations ... -
Analysis of pattern dynamics for a nonlinear model of the human cortex via bifurcation theories
(University of Waikato, 2014)This thesis examines the bifurcations, i.e., the emergent behaviours, for the Waikato cortical model under the influence of the gap-junction inhibitory diffusion D₂ (identified as the Turing bifurcation parameter) and the ... -
Modelling the spatial effects of the anaesthetic-induced phase-transition in the cerebral cortex
(University of Waikato, 2003)In this thesis I investigate the theoretical stochastic behaviour of a one-dimensional model of the cerebral cortex, exposed to varying concentrations of a general anaesthetic agent. The model is that of Steyn-Ross et al. ...
