The torsion balance is one of the key pieces of apparatus used in experimental searches for weak forces. In the search for an understanding of a Unified Theory, physicists have suggested a number of signatures that are detectable in laboratory measurements. This thesis describes…

Passive porous coatings have been proposed in literature as a means of delaying transition to turbulence in hypersonic boundary layers. The nonlinear stability of hypersonic viscous flow over a sharp slender cone with passive porous walls is investigated in this study. Hypersoni…
A major factor limiting the use and longevity of rare earth based magnetic materials is their susceptibility to aqueous corrosion and associated detrimental effects upon the magnetic properties of the material. This process was investigated through a combination of exposure to s…
The combustion and emissions performance of oxygenated fuels has been investigated in a modern direct-injection spark-ignition (DISI) engine. In particular, the new biofuel candidate, 2,5-dimethylfuran, otherwise known as DMF, has been assessed as a future automotive fuel agains…
The world is facing the challenge of global warming and environment protection. On the other hand, the demand of electricity is growing fast due to economic growth and increase in population. Since the growth in demand is also a heavy factor in energy equations, then the renewab…
Assembly systems today are exposed to market trends that have become increasingly more dynamic and unpredictable, requiring product changes and adjustments which emphasise de need for more flexible systems. The requirement for increased responsiveness has led to the development …
In this study an in depth investigation of successful competitive strategies for small to medium-sized enterprises (SMEs) is undertaken. The overall aim of this study is to analyse the strategic orientation of UK Manufacturing SMEs. In the process, it will test Porter’s (1980, 1…
Nowadays, New Product Development (NPD) has become a business priority in manufacturing companies due to international competition in terms of meeting higher and changing customer requirements, generating high profit at low cost, and maintaining sustainable development and growt…
Design of Experiments (DOE) is a powerful technique for understanding, characterising and modelling products and processes and improving their performance. Whilst the bulk of its literature revolves around how it should be applied, little attention, if any, is devoted to the man…
Laminated fibre reinforced polymer matrix composites have been used in design and manufacture for more than 50 years, exploiting desirable material properties such as high specific strength and stiffness, enabling large weight savings to be made on structural components. To take…
This thesis presents a new concept in steel-concrete-steel sandwich construction in which a bi-directional corrugated-strip core is proposed as an alternative inclined shear connector. The focus is on the feasibility study of fabrication techniques and the theoretical study of t…
In the light of the recent research interest in emulsion formation, this PhD thesis seeks to expand the current body of knowledge regarding the role of various emulsifiers on emulsion formation mechanisms. This study is particularly relevant to the food industries, where formula…
This thesis reports an investigation into the relationships between the tyre strain feature and tyre operating conditions based on finite element analysis and experiments for the development of a strain-based intelligent tyre system, which could estimate the tyre operating chara…
The future of manufacturing in high-cost economies is to maximise responsiveness to change whilst simultaneously minimising the financial implications. The concept of Reconfigurable Assembly Systems (RAS) has been proposed as a potential route to achieving this ideal. RASs offer…
Cutting and packing problems are increasingly prevalent in industry. A well utilised freight vehicle will save a business money when delivering goods, as well as reducing the environmental impact, when compared to sending out two lesser-utilised freight vehicles. A cutting machi…
Three HVOF and a VPS CoNiCrAlY coating were sprayed using Praxair CO-210-24 and Sulzer Metco Amdry 9951 powders. All coatings were subject to vacuum annealing treatments at different temperatures for different exposure times in order to achieve equilibrium microstructures in all…
Woven fabrics have found enormous application in our daily life and in industry because of their flexibility, strength and permeability. The aim of this work was to create a general model for through thickness air permeability and thermal conductivity for different types of text…
The objective of this research is to develop a design process that can optimize an engine casing assembly to reduce tip clearance losses. Performing design optimization on the casings that form a gas turbine engine's external structure is a very tedious and cumbersome process. T…
The research presented in this thesis explores the design and fabrication of microstructured and switchable biological surfaces, which may have potential applications of nanobiotechnology. The thesis focuses on the fabrication of biological surfaces which can be controlled via e…
