A stain-free detection system for electrophoresis
In this thesis, a novel stain free detection system for slab gel electrophoresis is examined. Currently, stained techniques are used to identify electrophoretic bands in gels. The stains utilized in these methods involve health risks since they are mutagenic. Also stains like EtBr are intercalating …

Characterization of the Acquisition Parameters of a Submersible Gamma-Ray Computed Tomography System
<p>"The purpose of this work is to study a component of a submersible gamma-ray computed tomography (CT) system used in the non-destructive testing of irradiated nuclear fuels. The first section of this study proposes two acceleration approaches for rapidly modeling a transmission-type gamma-ray …

A Multi-Resolution Direct Numerical Simulation of Turbulent Stratified Flows with High Prandtl Numbers
The turbulent structure of stratified open-channel flow subjected to a radiative volumetric heat source modelled by the Beer–Lambert law, for Prandtl numbers (𝑃𝑟) ranging 0.07 to 7, is investigated using direct numerical simulation (DNS). Most prior DNS studies of stratified turbulent open-channel …

Development of a method for automating effective patient diameter estimation for digital radiography
… lack of data containing a direct measurement of the patient diameter in the examination orientation or height and weight. This has meant that National Diagnostic Reference Levels (NDRLs) for paediatric radiographic examinations have not been updated in the UK since 2000, despite significant …

Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications
… routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be …

Phantom and computational studies towards the clinical translation of gas in scattering media absorption spectroscopy into neonatal respiratory care
… used by Robert Bunsen and Gustav Kirchhoff in the 1860’s to separate, identify and measure various chemical substances. They defined a line of research, where traces of elements were just detectable with the aid of specialized instruments like the spectroscope, and since then, the absorption …

Miniature gas sensing device based on near-infrared spectroscopy
The identification and quantification of atoms, molecules, or ions concentrations in gaseous samples are in great demand for medical, environmental, industrial, law enforcement and national security applications. These applications require in situ, high-resolution, non-destructive, sensitive, …
