The uncertainty and complexity of the interdependent global economy have amplified collective exposure of supply chains to disruptive events. In the construction world, the fragmented nature of the temporary project teams and the uncertain operating environment make construction…

Transportation is a central component to most political, economic, social and environmental issues throughout most inhabited societies. The concerns of transport have become widely acknowledged. It is broadly accepted that promoting alternative forms of transport such as walking…
One response to the increasing pressure of urban living is in the re-appropriation of public spaces and urban green to help sustain and enhance the environmental, social and cultural life of cities. But a major paradox arises here: while they are increasingly leaning on voluntar…
There is overwhelming evidence that the development of new, technically sound, engineered and fit-for-purpose critical physical infrastructure is vital for economic growth and stability. With many countries targeting significant levels of capital investment in energy, transport,…
The potential health consequences of carbon nanotube (CNT) exposure is often compared to asbestos and other fibre like materials due to their similar high aspect ratio and potential biopersistence; both are key in driving fibre toxicity and pathogenicity. With similar characteri…
P91 and P92 steels are two ASTM grades of steel which have been used in high temperature applications, such as fossil-fuelled power stations, nuclear power stations and chemical plants. Operating under creep conditions, i.e. high temperature and/or high stress, the welds made fr…
The Lost Foam Casting process has been firmly established for Aluminium and ferrous alloys. This process offers many advantages over conventional casting processes but its full potential has yet to be reached due to the many defects introduced to the casting associated with deco…
The main objective of this research was to understand phenomena occurring during food digestion and nutrients absorption in the small intestine from an engineering perspective. Intestinal flow and mixing processes were simulated using a dynamic in vitro Small Intestine Model (SI…
The thesis summarizes the research on the feasibility investigation of Space-Surface (i.e. a spaceborne transmitter and an airborne receiver) Bistatic Synthetic Aperture Radar (SSBSAR)with a Global Navigation Satellite System (GNSS) which is used as a transmitter of opportunity.…
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…
Food drying techniques such as air and freeze drying are not ideal: high temperatures used during air drying result in degradation of nutrients and sensorial properties, while freeze drying is expensive and therefore only applicable to high value foods. As an alternative to such…
Two sets of electrically small antennas in the form of coplanar meander dipoles have been designed and tested in this study. The meander dipoles are the anti-symmetrical and the symmetrical meander structures. Both sets were based on the 1.0 GHz linear halfwavelength dipole, i.e…
In this thesis high intensity focused ultrasound (HIFU) is utilized for cancer treatment (thermal mode) and treatment of ischaemic stroke (mechanical mode). These two applications were investigated in vitro and in vivo models. MRI was utilized to monitor the lesions created by H…
Wind action is particularly important for tall buildings, both in providing a significant contribution to the dynamic overall loading on the structure and by affecting its serviceability. Whereas low and medium-rise buildings are fairly rigid, tall structures are characterized b…
This thesis studies the relationship between the pairs of resonator output coupling and intra-cavity absorber initial transmission, and the FWHM (full width at half maximum) pulse duration of a continuously pumped passively Q-switched solidstate laser, when the output energy is …
This thesis discusses experimental results of measurement of heat transfer and velocity flow in a heated multiple cavity test rig with axial throughflow. Of particular interest are the internal cylindrical cavities formed by adjacent discs and the interaction of these with a cen…
The thesis describes a programme of work to develop a novel cellulose based fibre. The most important innovative step in this work lies in the manufacture of the fibre from a chiral nematic suspension of plant based cellulose nano-fibrils. In the course of the project a number o…
A study of the factors affecting the packing and porosity of particles has been made and a general theory for the combining of aggregates of varying shapes and sizes in order to achieve minimum porosity is proposed. Arising out of this theory experiments have been carried out fr…
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…
