This report thus investigates the subject of factor screening, for stochastic simulation models, and overviews several solutions to this problem. In particular, sequential bifurcation will be shown to provide a very efficient approach to the problem of factor screening, in comparison to standard one factor at a time classication methods.
Our scientific and technical publications are an important vehicle for the dissemination of our work.
We have several goals for our publications:
- To communicate the results of the research program to clients and fulfil our reporting responsibilities to the Department of Defence.
- To record the results of our research program.
- To communicate the results of scientific research and technical information to Australian industry and academia.
- To increase awareness of and enhance the reputation of DST Group.

A suitable model of the return ground clutter is required to help assess the performance of over-the-horizon radar. Currently, models for the clutter reflected from the sea exist but there are no models for the backscatter from land. The backscatter coefficient, which characterises the backscattered power, can be determined by considering the difference between observed backscatter ionograms and synthesised ionograms.
Five regions in Northern Australia were analysed and a dataset for the land backscatter coefficients was collated. The data analysis involved comparing the difference between observed backscatter ionograms (plots of the return power as a function of group range and frequency) and synthesised ionograms.
The Navy Aviation Systems Program Office (NASPO) requested DST analyse a red substance that had been identified around bearings in the lubrication system of several RTM322 engines.
In this report we propose a concept for a casualty evacuation stretcher with continuous monitoring and automated care functionality.
The present report expands on the analysis of the loading from a buried improvised explosive device (IED) for a variety of sands and soils, where it was considered for only dry calcite sand in a previous DST report.
There has been some work in recent years on investigating the use of machine learning (ML) techniques in order to assist software vulnerability discovery. Motivated by the spectacular success of deep learning (DL) approaches in fields such as computer vision and natural language processing, we propose to study the application of DL techniques to software vulnerability discovery.
In this report we describe a preliminary study on the considerations, assumptions, and options for managing the structural Life-of-Type (LOT) of new Royal Australian Navy (RAN) ships.
