Column separation on both the upstream and downstream sides of a valve in an aviation kerosene pipeline was the subject of an investigation involving the method of characteristics to solve the partial differential equations governing pressure transient propagation. Particular at…
Active vibration control techniques are widely used in linear time-invariant and nonlinear systems. However, there still exist many difficulties in the application of conventional active vibration control techniques, including the following: (1) In application, some of the degre…
The research presented in this thesis has been performed over the course of three years under funding from the European Office of the United States Air Force (EAORD) as a part of a long-term project to collect high quality data for the validation of computational mechanics model…
An approximate analytical technique for determining the survival probability and first-passage probability density function (PDF) of nonlinear multi-degree-of-freedom (MDOF) structural systems subject to an evolutionary stochastic excitation vector is developed. The proposed tec…
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 original contribution to knowledge made by this research work is demonstrating the benefits of differentially fed balanced transmit antenna in modern communication system. Extensive experimental studies have established the fact that a true differential amplifier feeding a b…
The focus of this dissertation is to present novel algorithms and techniques in wireless network systems aiming at performance optimisation. This thesis provides contribution to knowledge on the following topics: (a) sum rate maximisation of two interfering users in an Orthogona…
Compound Parabolic Collector (CPC) has numerous advantages such as high optical efficiency and wide applications. This thesis describes experimental and theoretical investigations of the effects of solar radiation available, design and orientation on different configurations of …
This thesis presents the findings of a research study investigating the energy-absorbing characteristics of the foam sandwich cores reinforced with aluminium, steel and carbon fibre-reinforced polymer (CFRP) cylindrical tubes under quasi-static and dynamic loading conditions. In…
The utilisation of process chains is considered as a way forward to achieve cost effective and high throughput production of miniaturised devices. However there are no methodologies to analyse systematically process chains and thus to inform their development and design new ones…
The performance of conical diffusers with axial and swirling flew has been considered. As a necessary starting point the various criteria used for defining performance have been reviewed and have been extended to swirling flew cases. A new 'AREA-PLOT' method, which unifies prese…
Almost 40 to 57% of Enterprise Resource Planning (ERP) projects fail to realise any benefit, run over budget or time. Only a few published works explicitly focus on ERP Critical Success Factors (CSFs) in Make-to-Order (MTO) manufacturing small and medium size enterprises (SMEs).…
This research work focused on evaluations of improving the acceleration, cold start transient performances and emissions in a common rail direct injection (CRDI) turbocharged diesel engine. The temperature impacts on the engine emissions were investigated at ambient temperatures…
The dynamic performance of a turbocharged diesel engine during transient operation has been studied. For appropriate analysis of data obtained from engine transient operation, four alternative automated filtering methods were implemented on the cycle-by-cycle in-cylinder pressur…
The thesis presented herein comprises of the work undertaken to research novel methods of Phased array ultrasonic inspection of complex steam turbine blade roots as found in the power generation industry. The research was conducted as part of the Engineering Doctorate scheme, ad…
Mathematical and computer-based models provide the foundation of most methods of engineering design. They are recognised as being especially important in the development of integrated dynamic systems, such as “control-configured” aircraft or in complex robotics applications. The…
This thesis presents an investigation on the churn to annular flow pattern boundary in an 11 m tall, 127 mm id vertical riser. Experimental data on film thickness, pressure drop and drop size and velocity was analysed and interpreted. Entrained fraction, interfacial and wall she…
This thesis examines the rheological behaviour and film formation of greases and oils under elastohydrodynamic (EHD) conditions. It approaches the lubrication of non-conforming contacts from tribological as well as from dielectric point of view. The experimental work was carried…
