Cold gas dynamic spraying (CGDS) is a recent development in the field of thermal spraying in which a powder feedstock can be deposited onto a substrate to form a coating without it being heated significantly. The aim of the present study was to investigate the potential for manu…

Polyimides are ubiquitous in the electronics, space science, and research industries due to their thermal stability, ease of use, lifetime, and high dielectric strength. These properties, along with the propensity of polyimides to absorb water vapour, has led to both their use a…
Frequent product model changes have become a characteristic feature in new product development and modern manufacturing. This has triggered a number of requirements such as shortening new product development time and production ramp-up time with simultaneous reduction of avoidab…
Recrystallisation is an important process for grain size control in steel, which is affected by the material grain size, alloy content, temperature, strain and strain rate. A crucial parameter for recrystallisation prediction is known as the Avrami exponent as this affects the r…
This thesis reports the results of an investigation of the effects of adding Tinuvin\(\char{msam10}{0x72}\)327 to PIC-100 acrylate resin on such important parameters as cure depth, critical energy, part density, dimension accuracy and surface quality. Initially, an experimental …
This PhD project was set out to improve the performance of silica gel / water adsorption cooling systems using a number of investigation tools. A novel global lumped analytical simulation model has been constructed for a commercialised two-bed silica gel / water 450kW adsorption…
This thesis presents a coherent, sustained and substantial contribution to the advancement of knowledge or application of knowledge or both in the field of construction management and economics. More specifically, this thesis outlines the strategic development of the built envir…
The growing demand for ever more greener aero engines has led to ever more challenging designs and higher quality products. An investigation into Coordinate Measuring Machine measurement uncertainty using physical measurements and virtual simulations revealed that there were sev…
Total disc arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of TDAs, but one of the most common is a ball-and-socket combination. Contact between the bearing surfaces of such designs can result in high friction…
In recent years, it has been recognised that a better understanding of processes involving particulate material is necessary to improve manufacturing capabilities and product quality. The use of Discrete Element Modeling (DEM) for more complicated particulate systems has increas…
Many foods contain large amounts of saturated fatty acids (SaFa), which are considered unhealthy, and their presence in the diet is one of the contributing factors of cardio-vascular disease, obesity and the inherent risk of diabetes. It has become the driver of food producers t…
Anaerobic digestion technology has not gained widespread acceptance on UK farms due mainly to the long return on investment periods involved. It has been suggested that co-digestion of agricultural and industrial wastes may enhance the economic viability of such installations. B…
The oxidation resistance of four prototype single crystal nickel-based superalloys for industrial gas turbine applications is studied. All contain greater quantities of Cr than in most existing single crystal superalloys; two are alloyed with Si, one with Re. To explain the resu…
Investigations into micro-slot milling of high carbon, high chromium hardened AISI D2 cold work tool steel using 0.5mm diameter coated (TiAlN) tungsten carbide end mills were carried out. Performance was assessed in terms of tool life/tool wear, surface roughness, cutting forces…
A possible way to continuously monitor the whole water distribution system is to equip pipes with many microsensors. If these sensors are to be integrated within the pipe walls, it is important to assess their impact on the structural integrity of the pipes. In order to test a l…
The static and dynamic properties of carbon fibre composites of varying orientation, stacking sequence and geometry has been analysed in terms of modulus and material loss factor up to strain rates applicable to golf club shafts. No noticeable change in modulus or damping was se…
Highly conductive (3.0 - 5.0 x 10 \(^{-4}\) \( Ω\) cm) and transparent (80 – 85% ) ITO films were successfully fabricated on glass and polymer substrates (PET, PEN and PC) by pulsed laser deposition at low temperatures (24 – 150 °C). The influence of deposition conditions on the…
Manufacturers are under pressure to reformulate products to make healthier foods, without changing desirability or flavour. A better understanding of product breakdown under oral conditions is essential to structure novel products which are healthier without consumers noticing. …
Concerns about changes in the quality of the maturing British spruce resource (principally stiffness) have raised doubts about maintaining strength grading pass-rates. Acoustic (or stress wave) instruments provide a non-destructive measurement of stiffness and are increasingly u…
In recent years, Millimetre-Wave (MMW) frequencies (30-300 GHz) have been exploited for a variety of attractive applications such as astronomical observation, medical imaging, aircraft aided-control landing, security and concealed weapons detection. All this was also possible th…
