Biosolids Reduction By The Oxic-Settling-Anoxic Process: Impact Of Sludge Interchange Rate, Galilee U. Semblante, Faisal I. Hai, Heriberto A. Bustamante, Nelly Guevara, William E. Price, Long D. Nghiem
Faculty of Engineering and Information Sciences - Papers: Part A
The impact of sludge interchange rate (SIR) on sludge reduction by oxic-settling-anoxic (OSA) process was investigated. The sludge yield of an OSA system (a sequencing batch reactor, SBR, integrated with external anoxic reactors) was compared to that of a control (an SBR attached to a single-pass aerobic digester). SIR (%) is the percentage by volume of sludge returned from the external reactor into the main bioreactor of the OSA, and was varied from 0-22%. OSA achieved greater sludge reduction when fed with unsettled sewage (sCOD=113 mg/L) rather than settled sewage (sCOD=60 mg/L). The SIR of 11% resulted in the highest …
The Impact Of Electronic Health Records On Risk Management Of Information Systems In Australian Residential Aged Care Homes, Tao Jiang, Ping Yu, David M. Hailey, Jun Ma, Jie Yang
The Impact Of Electronic Health Records On Risk Management Of Information Systems In Australian Residential Aged Care Homes, Tao Jiang, Ping Yu, David M. Hailey, Jun Ma, Jie Yang

To obtain indications of the influence of electronic health records (EHR) in managing risks and meeting information system accreditation standard in Australian residential aged care (RAC) homes. The hypothesis to be tested is that the RAC homes using EHR have better performance in meeting information system standards in aged care accreditation than their counterparts only using paper records for information management. Content analysis of aged care accreditation reports from the Aged Care Standards and Accreditation Agency produced between April 2011 and December 2013. Items identified included types of information systems, compliance with accreditation standards, and indicators of failure to meet …
The Impact Of Social Media Policy And Use On Value Creation: A Survey Research, Uuf Brajawidagda, Akemi T. Chatfield
The Impact Of Social Media Policy And Use On Value Creation: A Survey Research, Uuf Brajawidagda, Akemi T. Chatfield

Organizations need to provide effective policies in aligning their social media use with organizational goals to realize the expected benefits of social media. However, while social media use has been studied, social media policy research is lacking. This study aims to examine impacts of social media policy and active use on value creation. Drawing on the Model of IT/Business Value, we assessed the interplay between social media policy and social media use on value creation in a survey research conducted with Indonesia's disaster management agencies. Our analysis results of 124 survey responses show that social media use and social media …
Mri Geometric Distortion: Impact On Tangential Whole-Breast Imrt, Amy Walker, Peter E. Metcalfe, Gary P. Liney, Vikneswary Batumalai, Kylie L. Dundas, Carri Glide-Hurst, Geoff P. Delaney, Miriam M. Boxer, Mei Ling Yap, Jason Dowling, David Rivest-Henault, Elise M. Pogson, Lois C. Holloway

The purpose of this study was to determine the impact of magnetic resonance imaging (MRI) geometric distortions when using MRI for target delineation and planning for whole-breast, intensity-modulated radiotherapy (IMRT). Residual system distortions and combined systematic and patient-induced distortions are considered. This retrospective study investigated 18 patients who underwent whole-breast external beam radiotherapy, where both CT and MRIs were acquired for treatment planning. Distortion phantoms were imaged on two MRI systems, dedicated to radiotherapy planning (a wide, closed-bore 3T and an open-bore 1T). Patient scans were acquired on the 3T system. To simulate MRI-based planning, distortion maps representing residual system …
Impact Resistance Of Ultra-High Strength Concrete Beams With Frp Reinforcement, Alex M. Remennikov, Matthew Goldston, M Neaz Sheikh
Impact Resistance Of Ultra-High Strength Concrete Beams With Frp Reinforcement, Alex M. Remennikov, Matthew Goldston, M Neaz Sheikh
Faculty of Engineering and Information Sciences - Papers: Part A
Composite materials, including Fibre Reinforced Polymer (FRP) bars, have been used for decades in the structural and civil engineering sectors over traditional steel reinforcement. The main reasons for this are that FRP composites possess a number of advantages. They are non-corrosive, non-conductive, and lightweight and possess high longitudinal tensile strength. This paper presents the results of an experimental investigation into the effects of the use of glass FRP (GFRP) bars as internal reinforcement on the behaviour of concrete beams with high strength concrete (HSC) and ultra-high strength concrete (UHSC). Both static and dynamic (impact) behaviours of the beam have been …

Utilizing battery storage devices in plug-in electric vehicles (PEVs) for grid support using vehicle-to-grid (V2G) concept is gaining popularity. With appropriate control strategies, the PEV batteries and associated power electronics can be exploited for solar photovoltaic (PV) impact mitigation and grid support. However, as the PEV batteries have limited capacity and the capacity usage is also constrained by transportation requirements, an intelligent strategy is necessary for an effective utilization of the available capacity for V2G applications. In this paper, a strategy for an effective utilization of PEV battery capacity for solar PV impact mitigation and grid support is proposed. A …

Composite materials, including Fibre Reinforced Polymer (FRP) bars, have been gaining momentum as alternatives to traditional steel reinforcements in civil and structural engineering sectors. FRP materials are non-corrosive, non-conductive, and lightweight and possess high longitudinal tensile strength, which are advantageous for their use in civil infrastructure. This paper presents the results of an experimental investigation into the effects of the use of glass FRP (GFRP) bars as internal reinforcement on the behaviour of concrete beams. Both static and dynamic (impact) behaviours of the beam have been investigated. Twelve GFRP reinforced concrete (RC) beams were designed, cast and tested. Six GFRP …
