Spatialized Teleconferencing: Recording And 'Squeezed' Rendering Of Multiple Distributed Sites, Eva Cheng, Bin Cheng, Christian H. Ritz, I. Burnett
Spatialized Teleconferencing: Recording And 'Squeezed' Rendering Of Multiple Distributed Sites, Eva Cheng, Bin Cheng, Christian H. Ritz, I. Burnett
Dr Christian Ritz
Teleconferencing systems are becoming increasing realistic and pleasant for users to interact with geographically distant meeting participants. Video screens display a complete view of the remote participants, using technology such as wraparound or multiple video screens. However, the corresponding audio does not offer the same sophistication: often only a mono or stereo track is presented. This paper proposes a teleconferencing audio recording and playback paradigm that captures the spatial location of the geographically distributed participants for rendering of the remote soundfields at the users' end. Utilizing standard 5.1 surround sound playback, this paper proposes a surround rendering approach that `squeezes' …

Study Of Potential Risk Of Dengue Disease Outbreak In Sri Lanka Using Gis And Statistical Modelling, Sumith Pathirana, Masato Kawabata, Rohitha Goonatilake
Study Of Potential Risk Of Dengue Disease Outbreak In Sri Lanka Using Gis And Statistical Modelling, Sumith Pathirana, Masato Kawabata, Rohitha Goonatilake
Adjunct Associate Professor Sumith Pathirana
The increasing incidence of dengue fever has become a priority health issue for Sri Lanka. Recent dengue outbreaks in Sri Lanka show two trends: yearly increase of total number of dengue incidence and increasing dengue outbreaks outside the endemic urbanised areas in the south and the west. Identification of factors responsible for dengue outbreaks and the mapping of potential risk areas in Sri Lanka are long overdue. This study examines the association between weekly rainfall patterns and dengue outbreaks in the western province between 2000 and 2004. Methods: The study develops a model to quantitatively assess the relationship between rainfall …
Robust Distributed Scheduling Via Time Period Aggregation, Shih-Fen Cheng, John Tajan, Hoong Chuin Lau
Robust Distributed Scheduling Via Time Period Aggregation, Shih-Fen Cheng, John Tajan, Hoong Chuin Lau
Shih-Fen Cheng
In this paper, we evaluate whether the robustness of a market mechanism that allocates complementary resources could be improved through the aggregation of time periods in which resources are consumed. In particular, we study a multi-round combinatorial auction that is built on a general equilibrium framework. We adopt the general equilibrium framework and the particular combinatorial auction design from the literature, and we investigate the benefits and the limitation of time-period aggregation when demand-side uncertainties are introduced. By using simulation experiments on a real-life resource allocation problem from a container port, we show that, under stochastic conditions, the performance variation …

Propagation Of Tsunami-Driven Gravity Waves Into The Thermosphere And Ionosphere, Michael P. Hickey, G. Schubert, R. L. Walterscheid
Propagation Of Tsunami-Driven Gravity Waves Into The Thermosphere And Ionosphere, Michael P. Hickey, G. Schubert, R. L. Walterscheid
Michael P. Hickey
Recent observations have revealed large F-region electron density perturbations (~100%) and total electron content (TEC) perturbations (~30%) that appear to be correlated with tsunamis. The characteristic speed and horizontal wavelength of the disturbances are ~200 m/s and ~400 km. We describe numerical simulations using our spectral full-wave model (SFWM) of the upward propagation of a spectrum of gravity waves forced by a tsunami, and the interaction of these waves with the F-region ionosphere. The SFWM describes the propagation of linear, steady-state acoustic-gravity waves in a nonisothermal atmosphere with the inclusion of eddy and molecular diffusion of heat and momentum, ion …

Carolyn Windsor
Purpose – This paper aims to carry out a critical analysis of the proposed Australian emissions trading scheme (ETS) as a complex market solution to reduce greenhouse gases (GHGs). Specifically it seeks to examine the financial regulatory infrastructure that will more than likely oversee the Australian ETS, the same regulatory infrastructure which failed to prevent the global financial crisis.Design/methodology/approach – A critical examination of the financialisation of the atmosphere that follows the growth of the financialisation of capitalism when economic activity shifted from production and service sectors to finance. Financialisation of capitalism is supported by capitalist regulation influenced by neo-liberal …

Climate Change In The Dead Heart Of Australia, Joshua Larsen, Gerald C. Nanson, Timothy J. Cohen, Brian G. Jones, John D. Jansen, Jan-Hendrik May
Timothy Cohen
Despite the absence of large-scale glaciation, the Australian continent has experienced substantial environmental change throughout the Quaternary period. This is especially pronounced in central Australia, where one seventh of the continent is drained internally to the depocentre, and lowest point in Australia, Lake Eyre (Figure 1). Research has shown that at one time, large sandy braided and meandering rivers carried water through dunefields to a large freshwater lake system. Today, the rivers are hostage to the dunefield, and floodwaters might only reach Lake Eyre once every ten years or so. In order to understand the development of this arid desert …

The Effect Of Frictional And Adhesion Forces Attributed To Slurry Particles On The Surface Quality Of Polished Copper, Yi-Koan Hong, Ja-Hyung Han, Tae-Gon Kim, Jin-Goo Park, Ahmed A. Busnaina
Ahmed A. Busnaina
The effect of frictional and adhesion forces attributed to slurry particles on the quality of copper surfaces was experimentally investigated during copper chemical mechanical planarization process. The highest frictional force of 9 Kgf and adhesion force of 5.83 nN were observed in a deionized water-based alumina slurry. On the other hand, the smallest frictional force of 4 Kgf and adhesion force of 0.38 nN were measured in an alumina slurry containing citric acid. However, frictional (6 Kgf) and adhesion (1 nN) forces of silica particles in the slurry were not significantly changed regardless of the addition of citric acid. These …

Low Bit Rate Wideband Wi Speech Coding, C. H. Ritz, I. Burnett, Jason Lukasiak
Low Bit Rate Wideband Wi Speech Coding, C. H. Ritz, I. Burnett, Jason Lukasiak
Dr. Jason Lukasiak
This paper investigates waveform interpolation (WI) applied low bit rate wideband speech coding. An analysis of the evolutionary behaviour of wideband characteristic waveforms (CWs) shows that direct application of the classical WI algorithm may not be appropriate for wideband speech. We propose a modification whereby CW quantisation is performed using classical WI decomposition for the low frequency region and noise modelling for the high frequency region. Wideband WI coders incorporating this modification and operating at 4 kbps and 6 kbps are described. Subjective testing of these coders shows that WI is a promising approach to low bit rate wideband speech …

Parcel Subdivision Automation For Agent-Based Land Use Modelling, Rohan Wickramasuriya, Laurie Chisholm, Marji Puotinen, Nicholas Gill, Peter Klepeis
Nicholas J Gill
To a significant extent rural Australia is transforming into multifunctional landscapes. Amenity migration (i.e. movement of people from metropolitan to rural settings) is a major driving force of this transition in many areas. However, the effects of amenity migration on the receiving landscapes are not yet fully understood. Agent-based land use modelling helps unravel the complex spatio-temporal relationships that affect landscape response to change from amenity migration. A land subdivision module is essential for a complete agent-based land use model developed for these landscapes because the land sold to in-migrants are lots that are subdivided from much larger tracts. In …

Formation And Processability Of Liquid Crystalline Dispersion Graphene Oxide, Rouhollah Jalili, Seyed Hamed Aboutalebi, Dorna Esrafilzadeh, Konstantin Konstantinov, Joselito M. Razal, Simon E. Moulton, Gordon G. Wallace
Gordon Wallace
Rational control over the formation and processability, and consequently final properties of graphene oxide liquid crystalline dispersions has been a long-standing goal in the development of bottom-up device fabrication processes. Here we report, the principal conditions through which such levels of control can be exercised to fine-tune dispersion properties for further processing.
Revisiting 3d Stereo Satellite Image Displays, Frederick R. Mosher
Revisiting 3d Stereo Satellite Image Displays, Frederick R. Mosher
Frederick R. Mosher
Over 30 years ago, there were a number of development efforts to display 3D stereo satellite images and associated weather. Dr. Fritz Hasler showed how the GOES-east and west satellites could be remapped to generate true stereo pairs for obtaining cloud heights and he also showed how artificial stereo images could be generated using derived IR cloud heights to generate parallax shifts for the visible or infrared images. While there was a flurry of interest in the 1980s, the techniques had largely fallen from routine usage until recently. However, technology advances in both satellites and display technology has allowed for …

Mapping The Organizational Relations Within Physical Security’S Body Of Knowledge: A Management Heuristic Of Sound Theory And Best Practice, Richard Coole, David J. Brooks
Mapping The Organizational Relations Within Physical Security’S Body Of Knowledge: A Management Heuristic Of Sound Theory And Best Practice, Richard Coole, David J. Brooks
David J Brooks Dr.
Security Science education at university levels is still in its infancy, with little agreement towards knowledge, curriculum and competency. Therefore, it is essential that educators draw on relevant literature highlighting means of efficient and effective knowledge transfer for tertiary students within the Security Science domain. Such knowledge transfer will reduce the gap between academic knowledge (explicit) and professional competency (tacit knowledge). This paper presents phase one of a multiphase study. A qualitative “systems based knowledge structure” of security domain categories has been conceptually mapped as a domain heuristic. The heuristic drew on research highlighting that experts have both richer depths …

Incentives Critical To Full Wind Power Potential In Nebraska, Michael Neale
Incentives Critical To Full Wind Power Potential In Nebraska, Michael Neale
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
On August 3rd, President Obama and the EPA announced the Clean Power Plan (CPP) with the goal of cutting 32% of carbon emissions nationwide by 2030. The plan institutes carbon reduction requirements for all states based on their current sources of energy, for Nebraska the goal is 40%. The next day, Governor Ricketts and his Attorney General announced they would be fighting the mandate in court; stating the plan is unlawful federal government overreach, while expressing concerns the reduction are infeasible in the timeframe given and will drive up electricity costs. Governor Ricketts misses the point on this. Reducing carbon …
Inverse Modelling Of The Reversely Magnetized, Shallow Plumbing System Hosting Oil Reservoirs Of The Auca Mahuida Volcano (Payeina Retroarc, Neuquén Basin, Argentina), John Paine, Riccardo De Ritis, Guido Ventura, Mariana Longo, Dhananjay Ravat, Fabio Speranza, Massimo Chiappini
Inverse Modelling Of The Reversely Magnetized, Shallow Plumbing System Hosting Oil Reservoirs Of The Auca Mahuida Volcano (Payeina Retroarc, Neuquén Basin, Argentina), John Paine, Riccardo De Ritis, Guido Ventura, Mariana Longo, Dhananjay Ravat, Fabio Speranza, Massimo Chiappini
Earth and Environmental Sciences Faculty Publications
The Auca Mahuida volcano (2.03–0.88 Ma) located east of the Andean thrust front in the Neuquén basin (Argentina) hosts an oil system of thermogenic origin and is affected by the NW–SE striking-faults. Intrusive bodies and the underlying Jurassic sediments constitute the reservoir rocks. Aeromagnetic data collected in the Auca Mahuida area detected multiple dipolar magnetic anomalies, many of which have reverse polarity. Palaeomagnetic measurements on rock samples collected in the field together with available age determinations indicate that the reversely magnetized sources were mainly emplaced during the Matuyama reverse polarity chron while the normal polarity sources were emplaced during the …
