Electrospray of macro-molecules is of great interest in biomedical research for its finely controlled delivery of molecules. This thesis investigated mechanisms involved in electrospray of biological macromolecules. Hyaluronan, i.e. HA, for its biological significance, has been …
The influence of mechanical loading upon bone growth and remodelling has been widely studied. It has been suggested that functional bone growth is evident within the human adult pelvis, where the internal trabecular structure is purported to align to the principal strain traject…
The past recent years have seen a surge of evidence demonstrating the regulation of microRNAs (miRNAs) in a myriad of vascular biology events such as cardiogenesis. Nevertheless, the missing miRNA-link in controlling pluripotent human embryonic stem cell (hESC) fate in different…
The challenge faced by structural designers is becoming increasingly difficult as the imposed design criteria of energy absorbing structures requires weight reduction of structures without compromising cost and crushing performance. The current research is thus aimed at investig…
Optical motion capture is a powerful tool for human motion analysis. However, an intrinsic limitation of this method is its dependence upon line of sight, which when occluded, prevents measurement of position, resulting in data loss and failure of trajectory tracking. The thesis…
New experimental data are reported for free-convection condensation of ethylene glycol and R-113 on three-dimensional pin-fin tubes. Effects of pin geometry and tube thermal conductivity (for copper, brass and bronze giving a mean range of 400, 120 and 80 W/m K over the range of…
An increased demand of quality in the construction industry has been a major cause of finding new systems and developing frameworks that are fit for purpose. Construction companies around the world are trying to increase their productivity and index of quality and they are devel…
Aircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the effects of the shear layer. I…
Accurate and repeatable heat-transfer data are reported for forced-convection filmwise condensation of steam and ethylene glycol flowing vertically downward over two single, horizontal instrumented integral-fin tubes and one plain tube. Vapour-side, heat-transfer coefficients we…
The characteristics of a patient support interface can influence the susceptibility of subjects, particularly there who are immobilised and insensate, to pressure ulcer development. Accordingly, externally powered alternating pressure air mattresses (APAM) are utilised to produc…
Extracellular oxygen concentrations affect cellular metabolism and influence tissue function. Detection methods for these extracellular oxygen concentrations currently have poor spatial resolution and are frequently invasive. Fluorescence Lifetime Imaging Microscopy (FLIM) offer…
In this research we investigate the evaluation of usability evaluations methods (UEMs). In particular we are concerned with evaluating their suitability for the evaluation of location- aware systems. Not all approaches for the evaluation of UEMs have been extensively validated f…
Internal combustion engines are approaching their theoretical maximum efficiency, which could indicate limited future technological improvements in performance and exhaust emissions with standard fuels. In addition, fossil fuel dependence can only be reduced by implementing appr…
This thesis presents the development of three different methods for body joint angle measurement using wearable sensors. Continuous monitoring of patients' movements and activities has recently become one of the active research areas in the field of body sensor network and teleh…
In this thesis I show how self-assembled monolayers (SAMs) control the surface energetics and passivation of the oxide-freSi surface, and of semiconductor surfaces in general. The Metal-Insulator-Semiconductor (MIS) structure, suggested for cheap yet efficient solar cells, deman…
The Ultra-Wideband (UWB) system has emerged as a major solution for wireless communication due to its wide bandwidth and high data rate. As the deployment of UWB gathers pace, consumer electronic devices, PC peripherals and mobile devices manufacturers are striving to develop th…
This thesis consists of two main parts. In the first part a detailed wireless sensor node model based on CC2430, a system-on-chip IEEE802.15.4 compliance wireless transceiver manufactured by Chipcon, is proposed. The accuracy of the proposed sensor node model is compared with so…
The characterization of the oil based clay response used as a backing material during ballistic impact of light armor testing is essential in assessment of level of potential injury, and effectiveness and certification of the body armor. The current standard for quantification o…
