Improving the design of travelling wave type sloshing absorbers
… absorbers are simple structures consisting of a partially full container of liquid with a free surface. The primary objective of this thesis is to investigate the potential to improve the design of rectangular sloshing absorbers through attaching surface roughness elements (obstructions) to …

Design and analysis of privacy-preserving protocols
More and more of our daily activities are using the Internet to provide an easy way to get access to instant information. The equipment enabling these interactions is also storing information such as: access time, where you are, and what you plan to do. The ability to store this information is very …

An investigation of genetic factors impacting sterol profiles in Australian olive oils
Analyses of phytosterol levels in Australian olive oils derived from the cultivar Barnea (Olea europaea L. cv. Barnea)reveal up to 4.8% campesterol, exceeding the IOOC standards that stipulate a level of <4%. It has been observed that sterol profiles appear to remain relatively consistent within …

Some Inequalities Concerning Power Series and Their Interaction With Univalent Function Theory
Power series are fundamental in the study of Geometric Function Theory. In fact, they constitute a major part in Complex Analysis. The purpose of this dissertation is to employ analytic functions defined by power series in two different directions. The first of these discussed in Part I, mainly …

Ecological implications of allelopathic interferences with reference to Phragmites australis
The effects of plant invasions on ecosystem structure and function are well studied but the pathways and mechanisms that underlie these effects remain poorly understood. In depth investigation of invasion mechanisms is vital to understanding why invasive plants impact only certain systems, and why …

The control of turbulent flows around bluff bodies by means of spanwise sinusoidal profiles
Bluff bodies form ubiquitous components of many engineered structures. They are often exposed to turbulent flows, and the subsequent shedding of vortices gives rise to aerodynamic forces with large fluctuating components. As a result, significant oscillations are induced, which can lead to …

Catchment Scale Downscaling of Hydroclimatic Variables from General Circulation Model Outputs
… the atmosphere are considered the dominant cause of climate change. General Circulation Models (GCMs) are used for the projection of climate into future, accounting for the GHG concentrations. However, the coarse spatial resolution of GCM outputs does not permit their direct use in catchment scale …

A Novel Intrabody Communication Transceiver for Biomedical Applications
… uses body tissue as a propagation medium instead of air. While recent studies have shown a degradation of transmission signal for IBC between limb segments, these degradations have yet to be quantified with respect to relative limb positions. The current thesis investigates the influence of human …

Implementation of a digital signal processing (DSP) boost inverter for fuel cell energy generation
This thesis investigates and implements the use of a microprocessor called Digital Signal Processors (DSP) as a controller in the design of a low power inverter used in Fuel Cell energy source. The fuel cell used in this research is a Heliocentris “Constructor”, a 50W proton exchange membrane (PEM) …

Implementation of the IEC61850 international protocol for accurate fault location in overhead transmission lines
The rapid growth of electric power systems has resulted in many utility companies increasing the investment of Substation Automation Systems (SAS). Free marketing, deregulation and competition has brought about greater restrictive requirements to produce reliable, continuous and good-quality power …

Implementation of Renewable Energy to Reduce Carbon Consumption and Fuel Cell as a Back-up Power for National Broadband Network (NBN) in Australia
A reliable power is paramount and loss of power to communication equipment can mean loss of service to clients and loss of millions of dollars to industries. Also, climate is changing; greenhouse gas emissions from human activity are the major cause for global warming.
