A reversible outcome is one that can be changed. For example, the failure of an ongoing project may be avoided if certain actions are taken, while an outcome such as the path of a hurricane cannot be changed under current knowledge. The major benefit of predicting reversible outcomes resides in the possibility to avoid unwanted results. For this purpose, it(More)
Case-based reasoning is a flexible methodology to manage software development related tasks. However, when the reasoner's task is prediction, there are a number of different CBR techniques that could be chosen to address the characteristics of a dataset. We examine several of these techniques to assess their accuracy in predicting software development(More)
BACKGROUND During the 1918-1919 influenza pandemic, nurses and physicians were intensively exposed to the pandemic A/H1N1 strain. There are few published summaries of the mortality experiences of nurses and physicians during the pandemic. METHODS Mortality records from U.S. and British Armies during the First World War and obituary notices in national(More)
BACKGROUND Death rates in military populations outside of combat are often lower than those in the general population. This study considers how this "healthy soldier effect" changes over time. METHODS Standardized mortality ratios were used to compare changes in death rates relative to the Australian population in two large studies of Australian(More)
BACKGROUND This study assessed the extent to which alcohol consumption in a military group differed from the general population, and how alcohol affected the military group's health and social functioning. METHODS A cross sectional survey of military personnel (n = 5311) collected self-reported data on alcohol use (AUDIT scale) and general health, role(More)
BACKGROUND Frequent illness and injury among workers with high body mass index (BMI) can raise the costs of employee healthcare and reduce workforce maintenance and productivity. These issues are particularly important in vocational settings such as the military, which require good physical health, regular attendance and teamwork to operate efficiently. The(More)
Co-registration of clinical images acquired using different imaging modalities and equipment is finding increasing use in patient studies. Here we present a method for registering high-resolution positron emission tomography (PET) data of the hand acquired using high-density avalanche chambers with magnetic resonance (MR) images of the finger obtained using(More)
A method for the non-rigid, multi-modal, registration of vol-umetric scans of human hands is presented. PET and MR scans are aligned by optimising the configuration of a tube based model using a set of Bayesian networks. Efficient optimisation is performed by posing the problem as a multi-scale, local, discrete (quantised) search, and using dynamic(More)
