In this report we seek to evaluate the utility of dirichlet multinomial mixture (DMM) modelling of network metadata in roles such as source characterisation, detection of cyber security events, or volume filtering in support of same.
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.

In this report a material model taking strength and damage accumulation into acccount is implemented in the CTH hydrocode.
A static check-calibration of a Turbulent Flow Instrumentation (TFI) Dynamic Pressure Measurement System (DPMS) is performed and documented in this report.
Defence experimentation brings significant value, but also significant overheads. Therefore to achieve rapid development it is important to strike a balance between working on real systems and surrogate systems (when there is a straightforward translation to Defence systems and/or scenario). The emergency services domain is one such non-Defence surrogate system offering significant potential to mitigate many of these overheads.
This report proposes an M&S framework for evaluating ship performance in support of Royal Australian Navy acquisitions.
In this report we compare analytical and finite element solutions utilising COMSOL for calculating the magnetic induction of a permeable spherical shell with an internal current band in uniform magnetic induction.
An experimental investigation of an underwater explosion (UNDEX) induced whipping response was conducted on a submerged platform. The platform was subjected to eight near-field, non-contact UNDEX events, using two explosive charge sizes at three longitudinal positions along the hull length, coinciding with predetermined peak and node positions of the natural bending mode responses of the platform.
The Emerging and Disruptive Technology Assessment Symposium (EDTAS) series is a technology foresighting program under the Next Generation Technologies Fund designed to provide key insights and information on emerging and potential technologies over the longer term. In November 2017, DST joined with Noetic Group and the University of Melbourne to hold an EDTAS on Advanced Materials and Manufacturing.
In this report we focus on solving the Schrödinger equation numerically for several simple potentials using Fourier and Chebyshev pseudo-spectral methods.
