Following the first full term of regional government in the province since 1972, the Northern Ireland Assembly election held on 5 May 2011 saw the continuation of several trends. Foremost, the Democratic Unionist Party and Sinn Féin bolstered further their positions as leaders of their respective communities, with the Social Democratic and Labour Party and Ulster Unionist Party losing yet more ground. Building on their decision to enter power-sharing government together in 2007, the two largest parties framed themselves as the progressive choice for voters. As this was the first Assembly election since St Andrews (2006), much of the campaign dialogue centred on the prospect of a Sinn Féin First Minister, a concern highlighted by both unionist parties. The campaign also focused on ‘normal’ socio-economic political issues and possible institutional reform. The absence of inter-party conflict led to the campaign being perceived as the most mundane in living memory, with fears of a record low turnout realised.

This paper presents an automated design framework for the development of individual part forming tools for a composite stiffener. The framework uses parametrically developed design geometries for both the part and its layup tool. The framework has been developed with a functioning user interface where part / tool combinations are passed to a virtual environment for utility based assessment of their features and assemblability characteristics. The work demonstrates clear benefits in process design methods with conventional design timelines reduced from hours and days to minutes and seconds. The methods developed here were able to produce a digital mock up of a component with its associated layup tool in less than 3 minutes. The virtual environment presenting the design to the designer for interactive assembly planning was generated in 20 seconds. Challenges still exist in determining the level of reality required to provide an effective learning environment in the virtual world. Full representation of physical phenomena such as gravity, part clashes and the representation of standard build functions require further work to represent real physical phenomena more accurately.

The design of efficient assembly systems can significantly contribute to the profitability of products and the competitiveness of manufacturing industries. The configuration of a an efficient assembly line can be supported by suitable methodologies and techniques, such as design for manufacture and assembly, assembly sequence planning, assembly line balancing, lean manufacturing and optimization techniques. In this paper, these methods are applied with reference to the industrial case study of the assembly line of a Skycar light aircraft. The assembly process sequence is identified taking into account the analysis of the assembly structure and the required precedence constraints, and diverse techniques are applied to optimize the assembly line performance. Different line configurations are verified through discrete event simulation to assess the potential increase of efficiency and throughput in a digital environment and propose the most suitable configuration of the assembly line.

The recent drive towards timely multiple product realizations has caused most Manufacturing Enterprises (MEs) to develop more flexible assembly lines supported by better manufacturing design and planning. The aim of this work is to develop a methodology which will support feasibility analyses of assembly tasks, in order to simulate either a manufacturing process or a single work-cell in which digital human models act. The methodology has been applied in a case study relating to a railway industry. Simulations were applied to help standardize the methodology and suggest new solutions for realizing ergonomic and efficient assembly processes in the railway industry.

The results presented in this thesis have been achieved under the Ph.D. project entitled “Nonaqueous Sol-Gel routes to doped metal oxide nanoparticles: Synthesis, characterization, assembly and properties”. The purpose of this study is the investigation of metal oxide nanostructures doped with metals of a diverse nature, leading to different type of applications. The easier control over the reaction kinetics in solvothermal routes, compared to aqueous methods, allows to better match the reactivity between metal oxide precursors, paving the way to a facile and low temperature production of doped oxides. In this manuscript diverse examples of the exploitation of the “Benzyl Alcohol Route” are discussed. Such a powerful pathway was utilized for the synthesis of transition metal doped zirconia, hafnia and various perovskites, and the study of their magnetic properties, as well as the synthesis of rare earth doped zirconium oxide. A further extension, proving the solidity of the synthetic method, is shown for the preparation of Li4Ti5O12 nanocrystals carrying excellent electrochemical properties for lithium-ion battery applications. Finally, the effect of doping and other reaction parameters on the assembly of the nanocrystals is discussed. These studies were carried out principally at the University of Aveiro, as well as at the University of Montpellier II and at the Seoul National University due to complementary available expertises and equipments.
