Textualising British Politics: Deconstructing the subject of British foreign policy

British politics has been described as a sub-discipline crying out for methodological and ideational cross-fertilisation. Where other areas of political science have benefited from new ideas, British politics has remained largely atheoretical and underdeveloped. This has changed recently with the rise of interpretivism but the study of British politics would also benefit from more serious engagement with poststructuralism. With this in mind, I examine how the thought of Jacques Derrida and deconstruction could be useful for thinking through the foundations of British politics, re-examining what appears natural or given and revealing the problematic and contradictory status of these foundations. After suggesting the need to 'textualise' British politics', I illustrate how deconstruction operates in a specific context, that of British foreign policy since 1997. This exploration reveals how certain decisions (such as the invasion of Iraq in 2003) became possible in the first place, and how their basis in an idea of an 'us' and a 'them', a coherent, autonomous subject separate from its object, is deeply problematic. Such a critical reading of British politics is impossible within the dominant interpretivist framework, and opens up new possibilities for thought which form an important supplement to existing ways of studying the field.

Efficient modelling and optimisation of hybrid multilayered plates subject to ballistic impact

Among the key challenges present in the modelling and optimisation of composite structures against impact is the computational expense involved in setting up accurate simulations of the impact event and then performing the iterations required to optimise the designs. It is of more interest to find good designs given the limitations of the resources and time available rather than the best possible design. In this paper, low cost but sufficiently accurate finite element (FE) models were generated in LS Dyna for several experimentally characterised materials by semi-automating the modelling process and using existing material models. These models were then used by an optimisation algorithm to generate new hybrid offspring, leading to minimum weight and/or cost designs from a selection of isotropic metals, polymers and orthotropic fibre-reinforced laminates that countered a specified impact threat. Experimental validation of the optimal designs thus identified was then successfully carried out using a single stage gas gun. With sufficient computational hardware, the techniques developed in this pilot study can further utilise fine meshes, equations of state and sophisticated material models, so that optimal hybrid systems can be identified from a wide range of materials, designs and threats.

An Improvement of Subject Reacquisition by Reasoning and Revision

CCTV systems are broadly deployed in the present world. Despite this, the impact on anti-social and criminal behaviour has been minimal. Subject reacquisition is a fundamental task to ensure in-time reaction for intelligent surveillance. However, traditional reacquisition based on face recognition is not scalable, hence in this paper we use reasoning techniques to reduce the computational effort which deploys the time-of-flight information between interested zones such as airport security corridors. Also, to improve accuracy of reacquisition, we introduce the idea of revision as a method of post-processing.We demonstrate the significance and usefulness of our framework with an experiment which shows much less computational effort and better accuracy.
