Signal shadowing and multipath fading are two challenging phenomena in wireless communications. The goal of this thesis is to improve the statistical models and the mathematical tools required for description and analysis of some specific fading scenarios, namely lognormal shadowing, two-wave...
Development of an Efficient Quasi-3D Microfluidic Flow Model and Fabrication and Characterization of an All-PDMS Opto-Microfluidic Flow CytometerDownload
In this thesis, development of a novel microfluidic flow model, and, fabrication and testing of microfluidic cytometer for potential cell detection and sorting applications are described. The model is formulated by decomposing the flow profile along the height of microfluidic device into a...
Design of Asynchronous Cooperative Spectrum Sensing Scheme and Wideband Dynamic Spectrum Access Algorithm for Cognitive Radio NetworksDownload
Dynamic spectrum access (DSA) is a promising solution for mitigating the problem of crowded radio spectrum and enhancing the utilization efficiency of spectrum resources, making it a hot research topic. In DSA, spectrum sensing is crucial and cooperative spectrum sensing (CSS) is confirmed as a...
Development of compact fluorescent spectrometers and field deployable optical solids content monitoring devicesDownload
Two techniques were used to develop industrial and environmental sensing devices: fluorescence spectrometry and light scatter. The focus of the thesis is to develop real-time, portable and economical sensors using these techniques for environmental detection and management of tailings slurries. A...
A non-invasive label-free cytometry technique has been developed and advanced. This laser light scattering technique, alternative to the conventional fluorescent-activated flow cytometry (FACS) using biomarkers, identifies a micro scale particle or biological cell based on its two-dimensional...
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...
The cancellation of co-channel interference (CCI) is extremely vital in the nextgeneration wireless systems, where universal frequency reuse is commonly used to maximize the capacity. The implementation of CCI cancellation at the receivers instead of the transmitters minimizes the additional...
Development of Microfluidic Chips and a Customised Flow Control System for use in a Label-Free CytometerDownload
Conventional cytometry uses fluorescently labelled cells that are laborious and costly to prepare. Using a label-free technique, individual cells can be differentiated by light scattering patterns, a result of different physical attributes. This thesis describes the development of a microfluidic...
Magnesium is a promising material for solid state hydrogen storage applications owing to its high theoretical capacity of 8.2 wt% (H/Mg). Unfavourable thermodynamics coupled with poor kinetics leads to unacceptably slow sorption rates at modest temperatures and pressures. Approaches to increasing...
Strong nanoscale light-matter interaction is often accompanied by ultra-confined photonic modes and large momentum polaritons existing far beyond the light cone. A direct probe of such phenomena is difficult due to the momentum mismatch of these modes with free space light however, fast electron...
