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.

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.

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.

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.

Here we consider the application and suitability of the Joint Photographic Experts Group (JPEG) compression method and a simpler approach to Discrete Probability Density Maps (DPDMs).

In this report we focus on solving the Schrödinger equation numerically for several simple potentials using Fourier and Chebyshev pseudo-spectral methods.

This report provides a unified approach to the design techniques that they used to achieve the specified beam shape and sidelobe levels that are key performance requirements for airborne pulse-Doppler signal processing.
