Computer Science Faculty Research and Publications

Recently, there has been a growing interest in automatically collecting distributed solar photovoltaic (PV) installation information in smart grid systems, including the quantity and locations of solar PV deployments, as well as their profiling information across a given geospatial region. Most recent approaches are still suffering low detection accuracy due to insufficient sample and principal feature learning when building their models and also separation of rooftop object segmentation and identification during their detection processes. In addition, they cannot report accurate multi-deployment results. To address these problems, we design a new system-SolarDetector+, which can automatically and accurately detect and profile distributed …

Insights Into Prey Handling And Feeding Strategies By Ghost Crabs On Sea Turtle Eggs And Hatchlings, Casper Avenant

Research outputs 2022 to 2026

The feeding behaviour on sea turtle eggs and hatchlings by the golden ghost crab Ocypode convexa, a species endemic to the west coast of Australia, was observed in field and laboratory settings using infrared videography. On beaches where ghost crab densities are high, multiple crabs can feed on nests over several nights, often resulting in destruction of clutches. Crabs appear to anticipate the emergence of hatchlings, often congregating near nests in the moments prior to emergence. When feeding on eggs crabs rupture eggshells using the sharp tips of their claws, with tissue subsequently moved to the mouthparts for ingestion using …

Satellite And Eddy Covariance Analysis Reveals Short-Lived Evapotranspiration Changes After Fire In Mediterranean Woodland, Hoang Long Nguyen, Simone Gelsinari, J. Nik Callow, Richard Silberstein, Sally E. Thompson

Research outputs 2022 to 2026

Ecosystem evapotranspiration (ET) varies through space and time in response to environmental gradients and disturbances like fire. Field-based techniques (e.g. eddy covariance) can directly measure how ET responds to fire; however, these measurements are localised and only represent small areas. Remotely sensed ET products can potentially evaluate fire impacts on ecosystem ET, but their performance for this task remains largely unassessed. This paper uses three widely available remote sensing products: the CSIRO MODIS ReScaled ET (CMRSET), MODIS ET (MOD16), and Penman–Monteith–Leuning (PML), to assess ET changes caused by a fuel reduction burn in a Mediterranean woodland in comparison to the …

Thriving In The Tropics, Hansika K. Herath, D. Nicholas Mcletchie

Biology Faculty Publications

Increasing frequency and intensity of global warming pose a profound threat to plant species persistence. Most investigations on plants' resilience to heat events focus on few genotypes of model species. Novel insights into resilience mechanisms will be gained by focusing on natural variation in thermotolerance and its relationship to local-abiotic factors. Additionally, studying species that survived 'ancient periods' of high temperatures provides insight into resilience mechanisms. Within a species, we assessed spatial thermotolerance variation, its association with temperature and light, while testing for thermotolerance sex differences and its relationship with population sex ratios. We used Marchantia inflexa, a species with …

Mitigation Of Pm Eddy Current Losses Using Offset Windings In Coreless Afpm Machines, Matin Vatani, Diego A. Lopez Guerrero, John F. Eastham, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

Permanent magnet eddy current losses can become substantial in coreless stator axial flux permanent magnet (AFPM) machines operating at high speeds and under high electric loading, potentially leading to elevated temperatures and an increased risk of demagnetization. This paper investigates the origins of these losses through a detailed harmonic analysis of the winding factor and introduces a mitigation strategy. The proposed method utilizes two-layer offset windings, effectively minimizing undesirable armature flux harmonics through harmonic interaction between the offset layers. Two cases are studied: one in which each stator layer is connected to a separate inverter and another in which both …
