Formative Assessment To Develop Oral Communication Competency Using Youtube: Self- And Peer Assessment In Engineering, Sasha Nikolic, David Stirling, Montserrat Ros
Faculty of Engineering and Information Sciences - Papers: Part A
Obtaining oral communication competency is an important skill for engineering students to prepare them for interacting and working in any professional setting. For engineers, it is also important to be able to present technical information to non-technical audiences. To ensure oral competency, a non-graded formative assessment approach using video with self- and peer assessment was introduced into a final-year engineering thesis course. A low workload approach was used due to growing student numbers and higher pressures on academic staff. A quasi-experimental design was used to investigate the differences between traditional delivery, self-assessment and combined self-assessment with peer feedback. The study …

Field Assessment Of Ballasted Railroads Using Geosynthetics And Shock Mats, Sanjay Nimbalkar, Buddhima Indraratna
Field Assessment Of Ballasted Railroads Using Geosynthetics And Shock Mats, Sanjay Nimbalkar, Buddhima Indraratna
Faculty of Engineering and Information Sciences - Papers: Part A
The ballasted railroads form an integral part of the modern transportation infrastructure in Australia. However, they are subjected to large stresses especially on mixed traffic lines, where heavy freight trains are operated. Under such adverse operational conditions, ballast progressively degrades contributing to overall track deformations and frequent maintenance. Maintaining geometry of ballast embankments is necessary to improve safety and efficiency of railway operations. The use of artificial inclusions (geosynthetics and shock mats) as well as recycled (discarded) ballast in track can be economically viable options. In order to gain more insight, the CGRE has conducted extensive field trials on two …

Assessment Of Interface Shear Behaviour Of Sub-Ballast With Geosynthetics By Large-Scale Direct Shear Test, Mohammad Mahdi Biabani, Buddhima Indraratna, Sanjay Nimbalkar
Faculty of Engineering and Information Sciences - Papers: Part A
A series of large-scale direct shear test were conducted to study the interface shear strength of subballast reinforced with different types of geomembranes and geogrids. The impact of normal stress (σn), shearing rate (SR), relative density (DR) and open area (OA%) on the behaviour of granular material was investigated in unreinforced and reinforced condition. The results revealed that the performance of material was markedly influenced by σn and OA. The results also showed that geogrids provided a greater value of passive resistance owing to have transverse ribs, but the mobilised passive resistance became smaller with increase in OA. The triaxial …

An Assessment Of Image Distortion And Ct Number Accuracy Within A Wide-Bore Ct Extended Field Of View, Bradley Beeksma, D Truant, Lois C. Holloway, Sankar Arumugam
Faculty of Engineering and Information Sciences - Papers: Part A
Although wide bore computed tomography (CT) scanners provide increased space for patients, the scan field of view (sFOV) remains considerably smaller than the bore size. Consequently, patient anatomy which spans beyond the sFOV is truncated and the information is lost. As a solution, some manufacturers provide the capacity to reconstruct CT images from a partial dataset at an extended field of view (eFOV). To assess spatial distortion within this eFOV three phantoms were considered a 30 x 30 x 20 cm3 slab of solid water, the Gammex electron density CT phantom and a female anthropomorphic phantom. For each phantom, …

A Refined General Summation Law For Vu Emission Assessment In Radial Networks, Jayatunga Vitharanage Upuli Priyadarshani Jayatunga, Sarath Perera, Philip Ciufo, Ashish P. Agalgaonkar
Faculty of Engineering and Information Sciences - Papers: Part A
Voltage unbalance (VU) management of power systems requires the development of well researched engineering practices to maintain acceptable VU levels while utilising the total VU absorption capacity of the power system. In this regard, IEC/TR 61000-3-13:2008 prescribes a VU emission allocation methodology based on a stochastic approach which uses a general summation law in order to aggregate numerous sources of unbalance to take into account their random variations. On the other hand, recent deterministic studies on VU emission assessment at the post-connection stage of unbalanced installations present a complex VU factor based approach to determine constituent components of the post-connection …
Performance Based Seismic Assessment Of Bridges Designed According To Canadian Highway Bridge Design Code, M Neaz Sheikh, Frederic Legeron
Performance Based Seismic Assessment Of Bridges Designed According To Canadian Highway Bridge Design Code, M Neaz Sheikh, Frederic Legeron
Faculty of Engineering and Information Sciences - Papers: Part A
Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have been specified, there is no explicit requirement in the CHBDC to check the attainment of such performance objectives for the designed bridges. Also, no engineering parameters have been assigned to the specified performance objectives. This paper correlates seismic performance objectives (both qualitative and quantitative) with engineering …

Faculty of Engineering and Information Sciences - Papers: Part A
Context: A common distributed intelligent system architecture is Multi Agent Systems (MASs). Creating systems with this architecture has been recently supported by Agent Oriented Software Engineering (AOSE) methodologies. But two questions remain: how do we determine the suitability of a MAS implementation for a particular problem? And can this be determined without AOSE expertise? Objective: Given the relatively small number of software engineers that are AOSE experts, many problems that could be better solved with a MAS system are solved using more commonly known but not necessarily as suitable development approaches (e.g. object-oriented). The paper aims to empower software engineers, …

Steel cleanness is an important and growing research area driven by the demands to produce high quality steel. Lowering the inclusion content in steel is an important criterion for clean steel. It is therefore important to better understand the interaction between inclusions and slag to improve the removability of inclusions from liquid steel. For efficient inclusion removal the inclusions must attach/bond with the slag phase. The strength of the attachment can be characterised by the wettability of the slag on the inclusions. In this study, the dynamic wetting of ladle slags of the CaO-Al2O3-SiO2- MgO system on a solid spinel …

Faculty of Engineering and Information Sciences - Papers: Part A
Indirect carbothermal reduction of alumina for the production of aluminium has been claimed to be better compared to the existing Hall-Heroult process in-terms of energy usage, generation of perfluorocarbons and overall greenhouse gas emission. In the process, alumina is reduced to an intermediate compound which is then further reduced to Al. It has been shown from the previous thermodynamic study by the authors that high conversion of alumina can be obtained if it is reduced to Al-chloride, Al-nitride or Al-sulphide. This paper deals with detailed systematic thermodynamic analysis of the process through carbosulphidation route, where alumina is first reduced to …
