The cover of a scientific report
Our scientific output includes report literature

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.

Technical report
An investigation into the use of the Instron ElectroPuls E3000 for the purpose of fatigue crack growth rate testing of structural materials was conducted.

A comparative study of the two methods was carried out to ascertain whether the xCELLigence real-time cell analysis (RTCA) platform could be used to deliver a more objective and robust measure of TCID50.

Research report
A novel wavelet-based sparse signal representation technique is used to separate the main and tail rotor blade components of a helicopter from the composite radar returns. The received signal consists of returns from the rotating main and tail rotor blades, the helicopter body, possible land or sea clutter, and other residual components, which may all overlap in time and frequency; and therefore conventional time and frequency separation techniques cannot be applied. A sparse signal representation technique is now proposed for this problem with the tunable Q wavelet transform used as the dictionary. The proposed algorithm is demonstrated using both simulated and real radar data (X and Ku-band), and is capable of extracting the components of interest successfully.

This report outlines the results of a scoping study, subject matter expert discussions and workshop, and use case development for automated and autonomous systems for Combat Service Support.

Technical report
Armour steels have historically delivered optimised ballistic performance against a range of battlefield threats and continue to be highly competitive armour materials. The relationship between armour steel mechanical properties, specifically their mechanical metallurgy, and ballistic performance is explained, where such performance is primarily determined by material strength, hardness and high strain rate behaviour. Other important topics such as toughness; the adiabatic shear phenomenon; structural cracking; and dual hardness and electroslag remelted armour steels are also discussed along with armour steel specifications and standards.

The as-built out-of-circularity (OOC) deviations from a perfectly round shape and plate thickness variations of a cylinder that is subjected to external pressure are known to have a significant effect on the collapse strength and must be accurately represented in finite element analysis to obtain accurate results. Often it is necessary to interpolate measurements from a relatively coarse grid to a refined finite element model and methods that have wide general acceptance are Fourier series and bi-linear interpolation. These methods have been implemented in an Excel spreadsheet to produce node and element data that can be used directly in the Strand7 finite element package, but the methods employed are suitable for other software as well.

Technical report
System(s)-of-Systems (SoS) is broadly acknowledged as an engineering challenge for defence organisations, due to high complexity of various military SoS and their development processes. This report introduces a systems thinking-based approach, SoS thinking, which offers a language and a thoughtful process to conceptualise, understand, communicate about and assess military SoS.
Technical report
Technical report
The mechanical integrity of the propellant bed is a key factor in safe and consistent gun performance. A low strain-rate bed compression test was developed, primarily for use at low temperatures and, in conjunction with the time-temperature superposition principle, to simulate the high strain rates that exist in the gun chamber during ignition.
Technical report
Technical report
Recently, a novel tilted-wire' scatterer model has been developed that can provide an accurate and sparse representation of radar returns from such objects. Following a literature review on compressed sensing algorithms, covering both greedy and lp minimisation methods (0 < p ≤ 1), the report focuses on a comparative study of various greedy pursuit algorithms, using both simulated and real radar data, with a particular emphasis on the use of the tilted-wire scatterer model.

Technical note
These Research Notes form part of a series of notes extracted from work undertaken by Innovation Science in the establishment of Openness and Evolvability assessment Methods and Processes. This set of Research Notes focusses on an introduction to the assessment of Openness. This work was undertaken from the late 1990s to 2007 and focussed on the application to Submarine Combat Systems.
