The development of the plastic electronics industry has drawn great interest and inspired technology innovations in a broad area. This has stimulated the rapid development of flexible circuitry manufacturing technologies, including advances in conductive inks, printing technolog…
The motivation for this research is the synthesis and characterisation of nanostructured oxide materials for potential applications in renewable energy generation or storage. In particular, the research in this thesis addresses the development of nanostructured oxide materials w…
The ISO 9000 standards are widely used throughout the world, and are becoming the most important quality standards. Thousands of enterprises all over the world have already adopted these standards, with many more in the process of doing so. A range of benefits can be achieved by…
The overall aim of this research is to devise a climate change engagement modelling with an associated platform that would contribute to successfully engage the public and prompt them to move away from anti-environmental behaviour and closer to a sustainable lifestyle. The resea…
Nanoemulsions have been receiving a lot of interest due to their advantages: creaminess, better stability and more efficient delivery of neutraceuticals to the body. This work has developed the understanding of how to produce nanoemulsions efficiently using two high pressure dev…
The introduction of ceramic matrix composites (CMCs) for structural applications in the hot section of a gas turbine provides many potential benefits over conventional alloy materials, including facilitating elevated operating temperatures. The development of an oxide-oxide CMC …
Acoustic cavitation plays an important role in a broad range of biomedical, chemical and engineering applications, because of its magnificent mechanical and chemical effects. Particularly, the irradiation of the multi-frequency acoustic wave could be favouritely employed to prom…
The increasing size and flexibility of large wind turbine blades introduces significant aeroelastic effects, which are caused by fluid-structure interaction. These effects might result in aeroelastic instability problems, such as edgewise instability and flutter, which can be de…
The endurance of an aircraft can be increased in the presence of failures by utilising flight control systems that are tolerant to failures. Such systems are known as fault tolerant flight control systems (FTFCS). FTFCS can be implemented by developing failure detection, identif…
This thesis presents Computational Fluid Dynamics (CFD) simulations of renewable turbines akin to those used for wind, hydro, and tidal applications. The models developed took the form of actuator discs with the solution of incompressible Reynolds-Averaged Navier-Stokes equation…
In modern manufacturing industry, precision components are typically produced on Computer Numerical Controlled (CNC) machine tools which translate their accuracy onto machined parts. This accuracy is affected by a set of different motion errors caused by inherent imperfections i…
The sensors most commonly used for monitoring machine health are wired accelerometers because of their high performances and good stability. However, these transducers are usually large in size; require an external power source. Hence, there is a need for cheaper and reliable al…
Foreseen expansion and increasing complexity of power distribution networks will increase demand for accurate metering of electric energy flow. The current transformer (CT) is widely used in measurement systems and has direct effect on the overall accuracy of electric power meas…
Demand response (DR) is able to contribute to the secure and efficient operation of power systems. The implications of adopting the residential DR through smart appliances (SAs) were investigated from the perspective of three actors: customer, distribution network operator, and …
Task Planning is developed for an autonomous mobile robot in order to support the robot to accomplish tasks in various degrees of environmental complexity. This environment can be fixed or deterministic (as in a factory), dynamic (as in the human domestic household), or non-dete…
In this thesis an elastohydrodynamic lubrication (EHL) solution method has been developed for helical Gears. Helical gears mesh with each other and develop contact areas under load that are approximately elliptical in shape. The contact ellipses have aspect ratios which are larg…
Among the steady progression of disasters worldwide lie the numerous instances of fatality where crowds gather. The scale of these is particularly high at the Hajj in Makkah, where there are exceptionally high numbers of pedestrians in a number of confined areas and, depending o…
This research demonstrates that rubber particle size affects concrete workability and water permeability to a greater extent than fresh density and strength. Concrete with rubber particles of larger size tends to have a higher workability and fresh density than that with smaller…
