|
| Ultrasonic phased arrays will eventually replace conventional ultrasonic methods in many nondestructive evaluation (NDE) applications. However, the transition to phased arrays is not without its pitfalls and challenges. In this report we present a summary of the advantages and limitations of phased-array ultrasonics in NDE, with specific reference to the inspection of thick-section welds. The main advantages offered by phased arrays over conventional systems are increased sensitivity, coverage and speed. ... |

|
| The aim of this study was to quantify the secular changes in body dimensions of Royal Australian Air Force (RAAF) aircrew between 1971 and 2005. Small secular increases were observed for most body dimensions, including height, mass and body mass indices, although a small decline was observed for head girth. These secular changes (except for head girth) were not independent of changes in overall body size. In addition, secular changes ... |

| Social contacts are an important channel for the propagation of disease through a population and should be considered in conjunction with traditional epidemic diffusion. Such channels should always be taken into account for a realistic estimation of a long-term impact of a disease outbreak (natural or malicious) and for the best response options. This paper describes our recent experience in developing a simple agent-based model to simulate disease propagation through ... |

| While the arms industry has undertaken significant steps to globalize, NATO and ABCA (America, Britain, Canada, Australia) military force interoperability levels remain woefully inadequate. Over 60 years ago, NATO and the ABCA program sought to standardize the militaries of their member nations. Each member country agreed to take steps to ensure that interoperability among force elements was achieved. It is clear that a nexus should exist between globalized arms development ... |

| India's extremely diverse society has managed to hold together for over 60 years. There are a number of possible explanations for this, but one explanation that is often underappreciated is popular culture, and especially sports. Specifically, cricket has had a number of effects that would appear to have contributed to social cohesion in India. This thesis asks the following question: What effects has cricket had on the solidification of the ... |

| This project ultimately aims to identify the role of inhibin alpha (INHA) in advanced prostate cancer. The hypothesis to be tested is that INHA is tumor promoting and pro-metastatic in advanced prostate cancer. To date, we have made significant progress towards understanding the role INHA in advanced prostate disease. We have demonstrated that increased INHA expression in highly aggressive, metastatic and androgen-independent prostate cancer cell line, PC3, further promotes its ... |

| Entities in some simulations of military operations move unrealistically from point to point and are not constrained by their turning radius. The fidelity of this representation may be insufficient for operations research studies. In this paper a pursuer intercepting a target is considered, where the pursuer and target are moving at constant speeds in two dimensions and the target has a constant velocity. The minimum feasible path to interception for ... |

| Resistance to sulfur mustard (HD) penetration was investigated for two commercially available thermoplastic elastomers, Santoprene and Alcryn. To pass the Liquid Agent Vapour Penetration Test (LAVPT), Santoprene sheet needed to be at least 1.03 mm thick while Alcryn sheet needed to be at least 0.73 mm thick. Therefore, to pass the LAVPT, Alcryn sheet could be 29% thinner than Santoprene sheet. |
