Assessing The Vulnerability Of Pumping Stations To Trash Blockage In Coastal Mega-Cities Of Developing Nations, Robert Ighodaro Ogie, Sarah Dunn, Tomas Holderness, Etienne Turpin
Assessing The Vulnerability Of Pumping Stations To Trash Blockage In Coastal Mega-Cities Of Developing Nations, Robert Ighodaro Ogie, Sarah Dunn, Tomas Holderness, Etienne Turpin
Faculty of Engineering and Information Sciences - Papers: Part A
Pumping stations are important flood mitigation infrastructure used in coastal cities to remove accumulating floodwater from low-lying areas, where drainage is naturally poor due to very low slope gradient. In coastal mega-cities situated in developing nations, these pumping stations are often vulnerable to trash blockage as a result of frequent dumping of solid waste in water bodies. Given that blocked pumps are common causes of drainage infrastructure failure, the inability to identify the most vulnerable pumping stations can lead to inefficient allocation of limited resources for preventative maintenance of the drainage system. This study proposes an approach for measuring and …
Assessing Network Compliance For Power Quality Performance, Sean Elphick, Victor Gosbell, Victor Smith, Gerrard Drury, Robert Barr
Assessing Network Compliance For Power Quality Performance, Sean Elphick, Victor Gosbell, Victor Smith, Gerrard Drury, Robert Barr
Faculty of Engineering and Information Sciences - Papers: Part A
IEC standards suggest that a network is compliant if 95% of the sites are compliant. In many cases it is only practical to measure the PQ parameters of some of the sites in a network and to use statistical analysis. The paper examines the minimum number of monitored sites needed to demonstrate compliance with a prescribed degree of confidence - e.g. at the 95% confidence level. Analysis is made of samples extracted randomly from sites included in the Australian Long Term National PQ Survey. The required number of sites is found to vary with the PQ disturbance of concern and …
Assessing The Influence Of Climatic Variables On Electricity Demand, Dao Hoang Vu, Kashem M. Muttaqi, Ashish P. Agalgaonkar
Assessing The Influence Of Climatic Variables On Electricity Demand, Dao Hoang Vu, Kashem M. Muttaqi, Ashish P. Agalgaonkar
Faculty of Engineering and Information Sciences - Papers: Part A
The electricity demand is significantly dependent on the weather information. Such weather information is comprised of different climatic variables such as temperature, humidity, wind speed, evaporation, rain fall and solar exposure which constantly change. Therefore, analysing the impacts of these variables on demand is necessary for predicting the future change in demand. In this paper, the cooling and heating degree days are utilised to capture the relationship between the per capita demand to temperature, which is one of the key climatic variables. In addition, Pearson correlation analysis has been employed to investigate the interdependency between different climatic variables and electricity …
An Approach For Assessing The Effectiveness Of Multiple-Feature-Based Svm Method For Islanding Detection Of Distributed Generation, Mollah R. Alam, Kashem M. Muttaqi, Abdesselam Bouzerdoum
An Approach For Assessing The Effectiveness Of Multiple-Feature-Based Svm Method For Islanding Detection Of Distributed Generation, Mollah R. Alam, Kashem M. Muttaqi, Abdesselam Bouzerdoum
Faculty of Engineering and Information Sciences - Papers: Part A
Islanding detection is a critical protection issue, as conventional protection schemes such as vector surge (VS) and rate of change of frequency relays do not guarantee islanding detection for all network conditions. Integration of multiple distributed generation (DG) units of different sizes and technologies into distribution grids makes this issue even more critical. This paper presents a comprehensive analysis of the effectiveness of a new method for islanding detection in DG networks. The proposed method, which is based on multiple features and support vector machine (SVM) classification, has the potential to overcome the limitations of conventional protection schemes. The multifeature-based …
Assessing Students Understanding Of The Concept Of Free Body Diagrams Using Online Tests, Timothy J. Mccarthy, Thomas Goldfinch
Assessing Students Understanding Of The Concept Of Free Body Diagrams Using Online Tests, Timothy J. Mccarthy, Thomas Goldfinch
Faculty of Engineering and Information Sciences - Papers: Part A
There are many threshold concepts for students to grasp in Engineering Mechanics. Research has shown that one of the critical concepts that must be understood is the Free Body Diagram (FBD). This paper describes an approach to check students’ mastery of simple Free Body Diagrams and to address errors and misconceptions they may have. An online FBD quiz has been designed and implemented in a first year Engineering subject. Teaching material and follow-up support is targeted for students who struggle with the concept until mastery is achieved. These have been based on the theory of threshold concepts and the force …
