A New Data Driven Long-Term Solar Yield Analysis Model Of Photovoltaic Power Plants, Biplob Ray, Rakibuzzaman Shah, Md Rabiul Islam, Syed Islam

Faculty of Engineering and Information Sciences - Papers: Part B

Historical data offers a wealth of knowledge to the users. However, often restrictively mammoth that the information cannot be fully extracted, synthesized, and analyzed efficiently for an application such as the forecasting of variable generator outputs. Moreover, the accuracy of the prediction method is vital. Therefore, a trade-off between accuracy and efficacy is required for the data-driven energy forecasting method. It has been identified that the hybrid approach may outperform the individual technique in minimizing the error while challenging to synthesize. A hybrid deep learning-based method is proposed for the output prediction of the solar photovoltaic systems (i.e. proposed PV …

On Masking And Releasing Smart Meter Data At Micro-Level: The Multiplicative Noise Approach, John Brackenbury, P. Y. O'Shaughnessy, Yan-Xia Lin

Faculty of Engineering and Information Sciences - Papers: Part B

Smart meter electricity data presents privacy risks when malicious agents gain insights of private information, including residents’ lifestyle and daily habits. When allowing access to record-level data, we apply the multiplicative noise method to mask individual smart meter data, which simultaneously aims to minimise disclosure of a dwelling’s consumption signal to any third party and to enable accurate estimation of the sum of a cluster of households. Three testing criteria are introduced to measure the performance of multiplicative noise masking approach relevant to the smart meter data. We propose a novel ‘Twin Uniform’ noise distribution and derive relevant theoretical results. …

Surficial Sediment Data From The Shoalhaven River Delta: Bed Channel And Adjacent Beach, Rafael C. Carvalho, Colin D. Woodroffe

Faculty of Science, Medicine and Health - Papers: Part B

Estuaries on wave-dominated coasts generally comprise three sedimentary environments: fluvial sands and gravels derived from the catchment; marine sands characteristic of the beaches and nearshore; and silts and clays that accumulate in the sheltered central basin. Estuarine transition to deltaic form occurs when geomorphological maturity is achieved during coastal evolution. Sedimentary plains become infilled and a narrow channel connects the catchment and facilitates the transport of fluvial sediments to the coast. Here, we present modern sedimentary data that supports the idea that the wave-dominated Shoalhaven system in southeastern Australia has transitioned from an estuary to delta, transporting fluvial sediments to …

Are Urban Development And Densification Patterns Aligned With Infrastructure Funding Allocation? Examining Data From Melbourne 1999-2015, Nicole T. Cook, Ilan Wiesel, Fanqi Liu

Faculty of Social Sciences - Papers (Archive)

Densification of cities and suburbs is a contentious issue for many communities in lower-density settings. Local opposition to densification is often premised on concerns about the inadequacy of existing infrastructure to support growing populations and is strongest and most successful in wealthier neighbourhoods. While the urban consolidation agenda in cities such as Melbourne and Sydney is justified in policy contexts as a strategy to improve utilisation of existing infrastructure in built up areas, densification over time also produces new demand for services. Whether or not densification drives new infrastructure spending is therefore an important question in the governance of social …
