Geometrical Segmentation of Point Cloud Data by Spectral Analysis

Sergey Alexandrov
A principal step towards solving diverse perception problems is segmentation. Many algorithms benefit from initially partitioning input point clouds into objects and their parts. In accordance with cognitive sciences, segmentation goal may be formulated as to split point clouds into locally smooth convex areas, enclosed by sharp concave boundaries. This goal is based on purely geometrical considerations and does not incorporate any constraints, or semantics, of the scene and objects being segmented, which makes it...

think - The university of the future begins today

The central theme of the 2014 Annual Report is human thinking. In an interview, University President Hartmut Ihne and 3Sat moderator Gert Scobel discuss the concept of thought: "Should we be allowed to give up our autonomy voluntarily?" Our university’s Language Centre Director James Chamberlain examines to what extent thinking varies in different languages. Professor Paul Plöger from the Department of Computer Science explains why robots have tremendous problems understanding complex relationships in open environments....

Gay Community Periodic Survey: Sydney 1996-2002

Peter Hull, Paul Van de Ven, Garrett Prestage, Patrick Rawstorne, Andrew Grulich, June Crawford, Susan Kippax, Daniel Madeddu, David McGuigan & Antony Nicholas
Gay Community Periodic Surveys surveys are regularly conducted in Sydney, Melbourne, Brisbane, Cairns, Canberra, Adelaide and Perth to monitor changes in sexual and other risk practices over time among Australian gay men who are gay community attached, recruited from gay sex-on-premises venues, social sites and clinics.

Gove Northern Territory harbour feasibilty studies. March 1968.

P. B. Stone, D. N. Foster & R. C. Nelson
Investigations to provide design data for shipping operations on the gulf of Carpentaria at Gove.Waves due to trade winds and tropical cyclones were forecast for two possible harbour locations. The likely characteristics of seiche at one site was found unlikely to affect shipping. Current and sand movements were studied. Model studies investigated breakwater overtopping and harbour protection.

Investigation of EM31 anomalies at Yarramanbah/Pump Station Creek, on the Liverpool Plains of New South Wales. April 1998.

R. I. Acworth & R. Beasley
Describes the results of a detailed investigation program of the black soils of the Liverpool Plains, New South Wales, to determine the origin of high bulk electrical conductivity anomalies measured using a GEONICS EM31. Minimally disturbed core was obtained to 10m depth at four locations. Core was split into 100mm increments and tested for moisture content, cation exchange capacity, laboratory conductivity, grain size, XRD and fluid chemistry of 1:5 extracts. Field investigations involved conductivity imaging...

Monkey Mia: a hydrodynamic investigation. June 1998.

D. A. Luketina, I. P. King & L. M. Lyons
This report outlines the methodology and results of a RMA10 hydrodynamic model investigation funded by the Department of Conservation and Land management (W.A.) into the hydrodynamics of Monkey Mia lagoon and Shark Bay. More specifically, the model results show the dilution of a variety of neutrally buoyant pollutant releases in Monkey Mia Lagoon (Red Cliff Bay). In addition, the key processes governing the dilution are elucidated.

Berowra Creek: a hydrodynamic investigation. June 1998.

D. A. Luketina, D. C. van Senden & D. Piper
This report outlines the methodology for the analysis and interpretation of the results of a field investigation carried out in 1995 into the hydrodynamics of Berowra Creek, New South Wales. This investigation is centred around a three month set of data collected from May to August 1995. The data analysis is used to elucidate dominant physical processes so that models can be developed to predict flushing rates within the estuary.

Mitigation of siltation in farm water storages. May 1969.

R. T. Hattersley & R. C. Nelson
Present practices for the prevention of siltation in rural storages are reviewed in this report and compared with overseas practices. An anlysis of the effectivesness of conventional silt tanks is provided based on the approximate theories for settling of granular solids in sedimentation basins. A limited gtoup of case studies was made in an endeavour to highlight significant factors for the control and prevention of siltation in rural storages as topics for further research.

The assessment of the water resources of the Territory of Papua and New Guinea. October 1964.

C. H. Munro
Discusses importance of hydrological data collection. Present state of data collection in Papua New Guinea., New Britain, New ireland, Bougainville and Manus. Need for a national network. Detailed plan given, togther with proposals for training the indigenous people.

Flood forecasting for the City of Launceston. August 1960.

D. N. Foster

Wind induced oscillations of power station stacks. October 1962.

C. R. Dudgeon
Wind induced oscillations of welded steel smokestacks at Ptrmont have led to local buckling and fatigue cracks near the base. Observed double-amplitudes of the tops at 200 nfeet have been 2 to three feet. The most direct means of eliminating periodic interference or "buffeting' would be to prevent the regular shedding of eddies from upstream cylinders. The fitting of spoilers to the stacks of the kind investigated by Scruton and Walsh and by Weaver. The...

Finite element solution of two-regime flow towards wells. December 1973.

P. S. Huyakorn
The report has two parts. The first deals with the general theory, variation principles, and finite element methods for confined and unconfined flow problems. Numerical solutions for several transient and steady flow cases in graphical form. The second discusses verification of the analysis by laboratory and field investigations. Type curve methods developed for determining aquifer hydraulic coefficients are presented. Typical pumping test results are compared with the numerical solutions.

Non-continuous porous media flow. November 1965.

K. K. Watson
Non-continuous unsteady flow in unsaturated porous materials is defined and it is shown that time-dependent problems of this type, having varying bnoundary conditions, are represntative of many commonly occurring complex field situations. Experimental design and construction with literature review. Drainage of an initially saturated sand column to atmosphere at its base is studied from experimental and analytical viewpoint noting the hydrological characteristics of the sand fraction under dynamic conditions. Comparison of measured and computed moisture...
