Despite the enormous body of literature studying the typing errors of adults, children's typing errors remain an understudied area. It is well known in the field of Child-Computer Interaction that children are not 'little adults'. This means findings regarding how adults make ty…

Although the history of Virtual Reality (VR) is only about half a century old, all kinds of technologies in the VR field are developing rapidly. VR is a computer generated simulation that replaces or augments the real world by various media. In a VR environment, participants hav…
Currently, mobility is a significantly pervasive term; the concept is being widely used in multiple discussions including social, economic, political, and technological debates. However, the theoretical grounding of the concept is surprising unstable. This thesis aims to offer a…
This explorative study investigates how bureaucratic public sector client organisations deal with information technology (ITO) and business process (BPO) outsourcing in terms of internal management. To supplement the lack of studies emphasising pre-existing client organisational…
This dissertation provides fundamental conceptual building blocks for a new theory of IS implementation. The main argument presented is for a new perspective to supplement and complement the main existing perspectives on IS implementation: the technological determinist perspecti…
The ever increasing demand for higher power devices at higher frequencies has prompted much research recently into the aluminium nitride/gallium nitride high electron mobility transistors (AlN/GaN HEMTs) in response to theoretical predictions of higher performance devices. Despi…
X-ray absorption near edge structure (XANES) experiments on artificial pits of 316L stainless steel were carried out to study the oxidation state and speciation of alloying elements in the pit solution. It was confirmed that the oxidation states of Fe, Cr and Ni are 2+, 3+ and 2…
This thesis starts by reviewing superconductivity in one-dimension where fluctuations cause a loss of supercurrent due to an intrinsic resistance. Solved via the Ginzburg-Landau equations, the theory of thermally activated phase slips given by Langer and Ambegaokar is outlined. …
In this thesis, the design, fabrication and characterisation of a bio-inspired microelectromechanical systems (MEMS) based tactile sensor array is presented. A vast amount of research has been carried out in the area of tactile sensing and various transduction methods have been …
Understanding the physical processes which occur within open-channel flow is necessary if the modelling of river flow is to be improved. This thesis examines in detail the flow in a type of channel which is common in natural rivers yet little researched, the heterogeneous channe…
The World Wide Web has always attracted researchers and commercial search engine companies due to the enormous amount of information available on it. "Searching" on web has become an integral part of today's world, and many people rely on it when looking for information. The amo…
This research presents the study of processing panoramic spherical images for immersive visualisation of real environments and generation of in-between views based on two views acquired. For visualisation based on one spherical image, the surrounding environment is modelled by a…
Originally this research was to investigate the use of hydrostatic bearings in large linear machines, such as linear generators, and determine their viability in a power generation context. It quickly became clear that it was possible to make hydro-static bearings viable, howeve…
Compound semiconductor (III-V) devices are crucially important in a range of RF/microwave applications. High Electron Mobility Transistors (HEMTs), as the best low noise high frequency compound semiconductor devices, have been utilised in various applications at microwave and mm…
Creep damage is a time-dependent deformation in metals under a constant stress at high temperature condition. Since the 1980s, high chromium alloy steel P91 (9%Cr-1%Mo-0.25%V) is highly demanded in high temperature industries (Saha, 2003). Continuum damage mechanism is becoming …
Optical fibre systems have played a key role in making possible the extraordinary growth in world-wide communications that has occurred in the last 25 years, and are vital in enabling the proliferating use of the Internet. Its high bandwidth capabilities, low attenuation charact…
A visible light communication (VLC) system with green technology is available and enables users to use white LEDs for illumination as well as for high data rate transmission over wireless optical links. In addition, LEDs have advantages of low power consumption, high speed with …
Image retrieval plays a major role in many image processing applications. However, a number of factors (e.g. rotation, non-uniform illumination, noise and lack of spatial information) can disrupt the outputs of image retrieval systems such that they cannot produce the desired re…
Radical innovation has been identified as one of the central topics of innovation management, being relevant to the development process, the categories, and the R&D department’s responsibilities for development. Based on the above three individual research conversations, this re…
