In this article we present an approach to object tracking handover in a network of smart cameras, based on self-interested autonomous agents, which exchange responsibility for tracking objects in a market mechanism, in order to maximise their own utility. A novel ant-colony inspired mechanism is used to learn the vision graph, that is, the camera(More)
OBJECTIVES This study examined the effects of outdoor air pollutants in Sydney, Australia, on daily mortality. METHODS Time-series analysis was performed on counts of daily mortality and major outdoor air pollutants (particulates, ozone, and nitrogen dioxide) in Sydney (1989 to 1993) with adjustment for seasonal and cyclical factors. Poisson regression(More)
OBJECTIVE To determine the prevalence of iodine deficiency in primary school children in an Australian urban population. DESIGN AND SETTING A cross-sectional survey of school children aged 5-13 years attending a public school on the Central Coast of New South Wales in November 2000. PARTICIPANTS 324 (70%) of the 465 children enrolled in the school (180(More)
The functional consequences of the G80A RFC SNP on the expressed reduced folate carrier protein were evaluated by looking at the relationship between intake of folate, plasma folate and cellular stores of the vitamin. The effect on homocysteine was also examined. Homocysteine is a thiol that is known to be inversely associated with folate, and which is(More)
Smart cameras perform on-board image analysis, adapt their algorithms to changes in their environment, and collaborate with other networked cameras to analyze the dynamic behavior of objects. A proposed computational framework adopts the concepts of self-awareness and self-expression to more efficiently manage the complex tradeoffs among performance,(More)
To solve multi-objective problems, multiple reward signals are often scalarized into a single value and further processed using established single-objective problem solving techniques. While the field of multi-objective optimization has made many advances in applying scalarization techniques to obtain good solution trade-offs, the utility of applying these(More)
OBJECTIVES To determine whether pregnant women and their newborns show evidence of iodine deficiency, and to examine the correlation between maternal urine iodine concentration (UIC) and newborn thyroid-stimulating hormone (TSH) level. DESIGN A cross-sectional study. SETTING Hospital antenatal care services (March-May 2004) and private obstetrician(More)
In a study of the effects of indoor air pollution on the respiratory health of children in Newcastle, Australia, parental reports of symptoms experienced by children over the previous 12 months were compared with a prospective record of symptoms of cough and wheeze. Parents of 390 children aged 8-11 years completed a questionnaire about child and family(More)
—Novel computing systems are increasingly being composed of large numbers of heterogeneous components, each with potentially different goals or local perspectives, and connected in networks which change over time. Management of such systems quickly becomes infeasible for humans. As such, future computing systems should be able to achieve advanced levels of(More)
OBJECTIVES To describe the implementation of guidelines for vaccine storage in general practice, and their effectiveness in achieving optimum vaccine storage temperatures in fridges. DESIGN Repeated cross-sectional surveys over time--phase 1 1996/97, phase 2 1998/99, phase 3 1999/2000. SETTING Central Coast, New South Wales. PARTICIPANTS Phase 1--all(More)
