Engineering Physics

Digital Representation
Digital is an abstraction of analog voltage
Voltage is a continuous, physical unit
Typically ranging from 0 to 5 volts on PCs
Digital logic abstracts it to 2 distinct levels  “1” or positive (typically 2.5 V or greater)  “0” or negative (typically less than 1 volt)
Eases design and manufacturing

Solubility parameters of carbon quantum dots (CQDs) are important physical properties to deploy CQDs in various applications such as organic light emitting diodes (OLEDs), light-converting materials in LEDs, and photoluminescent sensors for metal ion detection. Because of the low toxicity and tunable emission most CQDs have been designed to be water-soluble and biocompatible; oilsoluble CQDs that are essential for OLEDs are not yet explored.

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

The limits of current micro-scale technology is approaching rapidly. As the technology is going toward nano-scale devices, physical phenomena involved are fundamentally different from micro-scale ones. Principles in classical physics are no longer powerful enough to explicate the phenomena involved in nano-scale devices. At this stage, quantum mechanic sheds some light on those topics which cannot be described by classical physics. The primary focus of this research work is the development of an analysis technique for understanding the behavior of strongly perturbed harmonic oscillators.

The overall aim of this study is to determine the most effective way to reduce the radiation dose to the breast during non-breast related CT scans, whilst still maintaining a suitable image quality. This study will attempt to compare the doses and noise of various protocols that can be used for dose reduction, including tube current modulation, bismuth breast shields and manual reduction of tube current.

The objective of this research is to study the effect of onset of physical fatigue/stress during isometric and dynamic contractions based on the changes in physiological signal i.e. SEMG. Therefore, the intention of this present investigation is to assess the repeatability of common muscle fatigue measures, including amplitude and spectral measures of EMG and further, to determine the adequacy of different measures in detection of onset of localized muscle fatigue.

Tensegrity is a structural system constructed of tensile cables and compressive bars. This thesis proposes several general methods for creating tensegrity structures. The author has developed new methods for creating specific tensegrity cells and the corresponding computer code. Furthermore, the author has constructed various physical models to validate the methods. A proposal for an observation tower on top of the Eureka building in Melbourne has also been devised by the author.

The primary aim of this research was to further develop the sensing and estimation module of the CHMS framework with an improved multimodal inference model of MWL as needed for the application in aerospace CPHS. Here the focus of this research was on the implementation of a multimodal inference model of MWL that would be developed and experimentally tested. This was done with the purpose of studying the viability of real‐time system adaptation in aerospace systems.

This research project "Prioritisation in infrastructure asset maintenance" aims to develop a reliable and accurate decision-making method for improving the maintenance prioritisation of irrigation infrastructure. The method should utilise agreed evaluation criteria, based on existing organisational policies and risk frameworks, and real-time data representing the physical condition of assets to prioritise them for maintenance.

This study uncovers a wide range of complex transport dynamics in transiently forced aquifers that has profound implications for the understanding and quantification of solute transport in these important groundwater systems. And the results in this thesis predict that complex transport structures and dynamics arise in natural transiently forced aquifers around the world. When such dynamics do arise, it will lead to mixing and reactive transport patterns that are very different from those predicted by conventional Darcy flow models.

The calculations showed that the results are comparable to the best MOFs for the hydrogen storage up to date. The results also elucidated that the gravimetric hydrogen uptakes depend on the special surface area and pore volume of the MIL-88s. These important structural features, if properly improved, lead to an increase in the capability of hydrogen storage in MIL-88s.
