The Wavelength-Oriented Microwave Background Analysis Team (WOMBAT) is constructing microwave skymaps which will be more realistic than previous simulations. Our foreground models represent a considerable improvement: where spatial templates are available for a given foreground, we predict the flux and spectral index of that component at each place on the sky and estimate the uncertainties in t...

Single crystal diffuse scattering was collected on the Wombat high-intensity powder diffractometer at the OPAL reactor at the Bragg Institute. The difficulty in measuring diffuse scattering comes from its relatively low intensity compared to the Bragg peaks, a factor of 10−10 smaller. Wombat allows collection of diffuse scattering due to its high intensity and large two-dimensional detector. Di...

In this paper, we present a new attack attribution method that has been developed within the WOMBAT project. We illustrate the method with some real-world results obtained when applying it to almost two years of attack traces collected by low interaction honeypots. This analytical method aims at identifying large scale attack phenomena composed of IP sources that are linked to the same root cau...

This work describes a genetic algorithm for the calculation of substructural analysis for use in ligand-based virtual screening. The algorithm is simple in concept and effective in operation, with simulated virtual screening experiments using the MDDR and WOMBAT data sets showing it to be superior to substructural analysis weights based on a naive Bayesian classifier.

The construction of habitat models is a repeatable technique for describing and mapping species distributions, the utility of which lies in enabling management to predict where a species is likely to occur within a landscape. Typically, habitat models have been used to establish habitat requirements for threatened species; however they have equal applicability for modelling local populations of...

Marsupials are an infraclass of mammals living primarily in Australasia and the New World. Well-known marsupials include kangaroos, wallabies, koala, possums, opossums, wombats and the Tasmanian devil. Three species, the koala, wombat and wallaby were chosen for this study. Three Koala (Phascolarctos cinereus), two wombat (Vombatus ursinus) and three Grey’s wallaby (Macropus greyi) mandibles, w...

Abstract In this study we evaluate the design and efficacy of Wombot, an exploratory robot used to environmental conditions within wombat burrows. Our purpose-built traverses through difficult terrain present in burrows whilst facilitating placement retrieval data loggers. preliminary results suggest that would result a long mite survival time which shows significant risk for spreading infestat...

Ion cyclotron waves at approximately 0.7 the ion gyrofrequency have been observed experimentally in the large volume helicon reactor WOMBAT. These waves are highly localized along the axis of the device where a 8 cm diameter, 2 m long. Ar II plasma column is produced. Spectral measurements reveal a four-wave interaction where energy is down-converted to the ion cyclotron mode from the helicon p...
