Processing of adaptive optics photoreceptor images and application to the study of healthy and diabetic retinas
(2017-11-17)
The introduction of adaptive optics (AO) into vision science has made it possible for clinicians to study the human retina in vivo with high-resolution images. The study of AO images of the cone photoreceptor mosaic is ...
A study on human error, safety culture and risk in radiation oncology
(2017-05-12)
In 2010 the New York Times wrote a series of articles on different radiation procedures including radiotherapy treatments. These articles highlighted a number of incidents that have occurred in the course of radiotherapy ...
A morpho-kinematic and spectroscopic study of bipolar planetary nebulae
(2015-09-28)
In this thesis, studies of the kinematic properties for a sample of Galactic bipolar planetary nebulae, based on optical and infrared observations, were performed us- ing a morpho–kinematic code, optical and NIR diagnostic ...
Polychromatic modelling of the human eye containing a GRIN lens
(2017-12-01)
The ingenuity and complexity of the human eye have attracted the interest of many researchers. In this thesis, we take a closer look at the polychromatic nature of the human eye, with special attention paid to the gradient ...
Quantum dots in bio-imaging and drug delivery
(2015-11-23)
This work explores a range of bionanomaterials, with particular attention to their influence on cell growth, function and fate. Also the issue of intracellular nanoparticles quantification has been addressed in experimental ...
Development of a high time resolution optical polarimeter for astronomy
(NUI Galway, 2018-12-17)
This work started in September, 2014 and initially started as an investigation of
the characterisation issues associated with using Electron Multiplying Charge-
Coupled Devices (EMCCDs) in a two beam polarimeter. It was ...
High Resolution Flood Illumination Retinal Imaging System with Adaptive Optics
(2012-07-16)
Retinal imaging has its advantages both in the research laboratory and medical applications. Acquiring high resolution in-vivo images of the retina requires some form of correction for aberrations. To address that, the ...
A Monte Carlo Investigation in External Beam Radiotherapy
(2011-09-30)
Monte Carlo techniques have been shown to be the most accurate method of
modelling radiation transport and dose deposition. With increasingly complex
radiotherapy techniques being employed in the continuing fight against ...
Development of a Probabilistic Multi-Zone Multi-Source Computational Model for Indoor Air Pollution Exposure Assessment
(2014-02-12)
Airborne Particulate Matter (PM) is a major environmental concern because of its known impacts on human health, and since the developed world population spends approximately 89% of its time indoors, PM in the indoor ...
Multi-wavelength and Polarisation Studies of Pulsars: the Crab, Vela, and PSR J0205+6449
(2014-12-11)
This thesis outlines the findings of a multi-wavelength and polarimetric study of
a number of rotation-powered pulsars. Polarisation studies of pulsars are just one
example of obtaining insight into the geometry of their ...
