Resource Efficient Configuration of an Aircraft Assembly Line

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.

1916-2016. The 1916 Easter Rising

Commissioned by An Post to commemorate the centenary of the Easter Rising, this illustrated book draws on eye-witness accounts to assess this key turning-point in modern Irish history. Leading historian Fearghal McGarry explores the impact of events at the General Post Office, as well as setting the rebellion in its wider historical context. His account concludes with an assessment of the Rising's commemoration since 1916 and a commentary on the definitive stamps issued by An Post to mark the formative event in the emergence of an independent Irish nation.

Still Rising: The Career Politician in the British House of Commons, the Cabinet and the Shadow Cabinet

There is a public perception that politicians in the United Kingdom are increasingly detached from the electorate due to the apparent increase in the number of ‘career politicians’ with a professional background in politics. This article examines the occupational backgrounds of successful candidates to the House of Commons of the United Kingdom between the 1997 and 2010 general elections, comparing the parliamentary compositions of the three main political parties (Conservatives, Labour and Liberal Democrats) during this period, and the Cabinet and Shadow Cabinet as of 2014. By evaluating original and secondary quantitative data, it is argued that professionalised politicians have increased in the House of Commons relative to other occupational backgrounds, and are even further disproportionately represented in the senior teams of each major party.

Enhanced durability of Li-O2 batteries employing vertically standing Ti nanowire array supported cathodes

Ti nanowire arrays vertically standing on Ti foam prepared by a facile corrosion method were used as self-supported Li-O₂ battery cathodes. The batteries exhibited enhanced durability at high rate current densities (e.g. cycling 640 times at 5 A g^-1).
