Driver training and education initiatives are often considered the cornerstone of many organisational fleet safety approaches, however there is currently little evidence regarding the effectiveness of such interventions. Similarly, the evidence regarding the value of other programs such as driving incentives also remains mixed, as fleet managers search to identify cost-effective methods to reduce the burden of fleet crashes. This paper reports on the development and implementation of a driving diary within a fleet setting that aims to increase personal insight and safety through the identification of aberrant driving behaviours. The driving diary is based upon brief intervention techniques used successfully in the health care arena over the last twenty years, and thus the tool aims to reduce engagement in unsafe driving practices. The driving diary is currently being trialled with a large sample of fleet drivers in Queensland. Drivers are being asked to keep a driving diary for ten days, noting times and places associated with unsafe driving behaviour. A follow up survey and formative focus groups is underway to determine the relative effectiveness and utility of the intervention in a fleet setting. It is hoped the intervention will prove to be a time limited, low cost, evidenced-based tool that can influence behavioural change. In addition, it is anticipated the results of this project will add to the body of knowledge regarding fleet safety, particularly the driver behaviour change literature. This paper will further outline the major advantages and pitfalls associated with developing safety interventions within the fleet industry, as well as provide direction for future research-based initiatives.

We investigate the possibility of using fractal geometry to construct radiating elements for phased array radar. We seek to understand whether the characteristics of individual fractal designs can give rise to multi-band or broadband performance and we do this by looking at Hilbert curves, log-periodic and circular-log-periodic radiating elements. We present the theory and discuss software that has been developed in order to model fractal elements and we present our findings accordingly., The original document contains color images.

Occupational fleet safety is an emerging issue for organisations across Australia and overseas. Research has shown that road crashes are the most common cause of work-related fatalities, injuries and absences from work. Changes in industry/employer accountability, business processes, Occupational Health and Safety, Chain of Responsibility (COR), Workers Compensation legislation, insurance and third party coverage, and a generally more litigious environment require industry to address and subsequently develop more comprehensive programs to improve fleet safety. Historically, organisations opt for a silver bullet or singular reactive strategy towards fleet safety, determined primarily from an asset management approach. Research has revealed that a single reactive approach is ineffective in improving long-term occupational fleet safety. This paper focuses on examples of case study research conducted by the Centre for Accident Research and Road Safety – Queensland (CARRS-Q), involving fleet safety of three large and diverse Queensland and nationwide industry organisations. From analysis and investigation of vehicle crash/incident data, industry focus groups, and organisational safety and work-related driving survey questionnaires, current fleet safety practices and high risk groups and processes are identified. Subsequently, data from research and analysis reveals inadequacies in fleet safety practices current within organisations and enables the identification of future occupational fleet safety intervention strategies.

A transverse resonance mode matching technique has been developed to analyse passive microwave and millimetre wave waveguides and components. This technique possesses superior computational efficiency when compared to more general approaches such as the finite element method. This advantage is particularly useful for analysing broadband components used in electronic warfare systems. In this report, the theory behind this transverse resonance analysis is presented in detail. Theoretical results for several waveguiding structures are presented and compared with experimental or published data to verify the analysis.
