Termination of heavy-duty synthetic fibre ropes has long been an issue of concern in marine environments. Recent serious rope accidents and new requirements for lighter ropes with better performance in mooring lines have encouraged industry to look for new methods for increasing line performance using existing ropes. One way of increasing rope performance is to use efficient methods for rope termination. This is why the main objective of this study has been to investigate a new method for rope termination. Rope failure usually happens inside or very close to termination due to high stress concentration areas. The new method, "The Vaseghi Stress Relief Socket", has been proposed to improve the high stress concentration areas inside sockets and move failure points along the rope. The new method has increasedthe tensile performance of existing ropes up to 13%. It should also be addedthat the ropes in this study are mainly used in marine environmentsfor mooring oil platforms. Considering the results of the tensile and cycling tests, The Vaseghi Stress Relief Socket, proved a great potential for replacement of existing methods of termination e.g. the splice. It should also be noted that the reproduction of the socket termination is more consistent than that of other methods of termination. Tensile properties of ropes using `The Vaseghi Stress Relief Socket' were initially a matter of concern, for rope termination is the most important feature of ropes.In fact, if there is a termination failure in tensile tests, the rope will not be considered efficient for mooring purpose even though its other performancesare excellent. Load cycling was the second property that was considered. Acoustic Emission monitoring was performed to find out the relation between the load-extension behaviour of the rope using The Vaseghi stress Relief socket and the AE signals. Finally, the finite element modelling of socket helped to investigate the stress concentration areas in the socket to optimise the amount of the reinforcing material and identify the weak point areas in the socket, which could lead to further research studies for new designs.

In recent years, the nasal route has received a great deal of attention as convenient and reliable method of systemic administration of drugs, due to its benefits of reduced pain, precise drug delivery and eliminated risk of intravenous needles. The pharmaceutical industries are facing a competitive challenge introducing novel devices for the nasal drug delivery, which is better than commercially available, unit dose and squeeze bottle sprayers. The purpose of this study is to develop such a device for the nasal drug delivery that would satisfy the needs of the patients, physicians and pharmacist. An electronically controlled multi-dose nasal drug delivery device is developed as a result of the study. The parts of the device are designed to satisfy customer needs. The developed parts are redesigned for manufacture and assembly, considering the DFMA principles. The conceptual design was tested for its functionality by developing working prototypes of using rapid prototyping techniques. Suitable materials and manufacturing processes for parts of the device are determined, and the manufacturing and assembly cost of the device is estimated to justify affordability.

Eco-efficiency improvements in manufacturing is a controversial subject for researchers, practitioners as well as policy makers. The widely accepted definition of "doing more with less" is not accurate enough to guide the design of improvements that can deliver products in a sustainable way. The outcome of these challenges is evident through significant environmental performance variations across various levels of manufacturing operations. The study is driven by the complexity of manufacturing systems and sought to offer design support for practitioners that aim to improve eco-efficiency. A maturity model has been developed in this work that simulates the influence of manufacturing practices on eco-efficiency. The model takes the form of a maturity grid (PMGE) that overlooks practices at process, management systems and top-management levels and incorporates 15 dimensions of performance overall. Evidence shows that practices tend to evolve from reactive to proactive as manufacturing systems mature and embrace eco- efficiency as a systemic property. It was also found that mature companies achieve improvements in energy and resources by relying on existing internal capabilities. Tools to facilitate research and intervene with practitioners in real-life problems were developed and tested. The researcher combined research findings and tools into a maturity-based method (PMGEM) for eco-efficiency improvements. The method intends to help practitioners plan and design eco- efficiency improvements aligned to existing internal capabilities and adopt a more proactive behaviour to environmental challenges. PMGEM was ultimately applied in two case studies with ultimate goal to help practitioners resolve real-life challenges. The applications were positively commented and encourage further work in this field. The researcher envisages that methods such as PMGEM are deeply needed in manufacturing to support practitioners approach complex concepts such as eco-efficiency. Simplification and decomposition techniques with a clear intended use can facilitate the implementation of ambitious improvement strategies for sustainable development.
