This paper presents a solution to predict enemy vehicle movements and generate optimal interception paths for military command and control software. Fast and accurate prediction and interception systems can aid command decisions by presenting a refined view of otherwise complex information. The solution presented uses agent based modelling for vehicle movement simulation and a decision tree search to find an optimal interception path. Simulation results are presented to demonstrate the effectiveness of these approaches. © 2011 IEEE.

The high cost of major hazard facility (MHF) accidents, in terms of loss of lives, serious injuries, loss of production and associated cost of reputation and legal costs, require major hazard facilities to operate in a regulated regime designed to control major accidents. The Australian goal-setting regulatory regime is characterised by fragmentation in terms of jurisdiction, administration, reporting of near misses and classification of MHFs. Implementation of MHF regulation falls to the control of State and Federal jurisdictions, leading to some inconsistency in interpretations, as well as the additional complexity of process and high cost of developing Safety Case documentation. Specifically, this expansive rework on compliance activities impacts on all national/international concerns that have operations in multiple states and thereby consequential exposureto higher expenses and competitive disadvantages. The discussions in this paper include: a basic comparison of MHF regulatory framework applied in different Australian jurisdictions and the impact of proposed harmonisation of Australian OHS legislation on reducing the risk of major accidents at MHFs.

In this paper power cepstra measured in shallow waters are derived theoretically to show how a sound source propagating via different paths interferes. From the derivation several useful properties of the power ceptra are revealed, which could be used to classify rahmonic tracks generated by different paths and mechanisms. Sea trial data measured in a shallow water bay are analyzed to verify the properties of the power cepstra. © 2013 IEEE.

An optimal design of preamplifiers is proposed for broadband (BB) passive sonars, in which the frequency response function (FRF) of a preamplifier is optimized to maximize the output signal-to-noise ratio (SNR) of BB passive processing. The optimal design depends on passive source signals, background noise and array shapes. It contrasts with the conventional design where preamplifiers are used for whitening or conditioning hydrophone signals due to historical reasons. A hull-mounted 2-D virtual array is used as an example to show the advantage of the proposed optimal design. © 2013 IEEE.

This review paper will address the Australian history of electronic ceramic materials which were used primarily for their dielectric properties rather than their insulation properties. The history of these materials can be broken down into three main periods. The first period is that prior to 1950, when the electronic components industry was first set-up. The second period from approximately 1950 to 1975 involves the expansion and decline of the capacitor product lines and production capacity under the Ducon Condenser Company. The third period from approximately 1975 and continuing to the current day, involves the manufacture of piezoelectric components and devices through Ausonics Pty Ltd and a group at Plessey Ducon, which was subsequently managed in turn by its successors, Plessey Australia, GEC Marconi, Thomson Marconi and the Thales Australia companies. © 2014, Australasian Ceramic Society.
