Students in global service-learning and similar programs frequently encounter substantial social, cultural, political, and ethical differences when working with project partners in different countries and regions. Neglecting such differences can lead to project failures and/or disempowered communities. In response to these challenges, educational resources have been developed to teach students to think about how the people, social structures, and other contextual factors associated with projects can affect, and be affected by, students’ designs. Yet, there remains a scarcity of valid and reliable instruments to evaluate the effectiveness of such interventions. The purpose of this study is create a theoretically and …

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 …

Adventures in paragraph writing: the development and refinement of scalable and effective writing exercises for large enrollment engineering courses. The ability to communicate effectively is a highly desirable attribute for today’s graduating engineers. Additionally, the inclusion of communication components in technical courses has been shown to enhance learning of technical content and can be leveraged to satisfy non-technical learning outcomes. However, the incorporation of such components in undergraduate engineering curricula remains challenging due to resource limitations, credit hour crunches, and other issues. This paper presents the design considerations and preliminary results from our ongoing work to create an effective, transferrable, …

Australian railways offer an efficient and economic mode for transporting freight and passengers across all States. Conventionally, rail tracks are positioned on ballast for reasons including economy (availability and abundance), rapid drainage, and high load bearing capacity. However, the ballast becomes fouled due to the intrusion of fines either from the subgrade or surface which impairs track drainage. In order to maintain serviceability, it is necessary to maintain adequate drainage capacity in the track. To identify the risk associated with fouling, it is important to understand the effects of the amount of fouling on drainage conditions. In this present study …

The ability to collect data using sensor-based technologies is increasing within a public technical means. As governments in rapidly-urbanising developing nations seek to address the climatic, social and economic challenges of the 21st century, there is a progressive requirement to map and articulate civil infrastructure. When a local government needs to proactively react to impending and disruptive phenomena they increasingly look to data and technology to help them manage and respond accordingly. Mobile social media, in a citizens-as-sensors paradigm, offers the potential to collect data with which to advance our capacity to understand and promote resilience of cities to both …
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 …

Evolving Formative Assessment For And With Ubiquitous Technologies, Nadine Adams, Anne Porter
Faculty of Engineering and Information Sciences - Papers: Part A
Formative assessment is a vital part of the learning process. It guides student learning and prepares them for summative assessment. The feedback that accompanies formative assessment is valuable for students' learning. The combination of formative assessment and feedback facilitate the development of self-efficacy. Technology is not only changing the way students study and learn but also how assessment is conducted and managed. Globalisation and corporatisation of universities has changed the way academics work and has had an effect on teaching, assessment and feedback. This paper looks at how formative assessment in an enabling mathematics course has been developed to take …

Background: b-amyloid (Ab) plaques in brain’s grey matter (GM) are one of the pathological hallmarks of Alzheimer’s disease (AD), and can be imaged in vivo using Positron Emission Tomography (PET) with 11C or 18F radiotracers. Estimating Ab burden in cortical GM has been shown to improve diagnosis and monitoring of AD. However, lacking structural information in PET images requires such assessments to be performed with anatomical MRI scans, which may not be available at different clinical settings or being contraindicated for particular reasons. This study aimed to develop an MR-less Ab imaging quantification method that requires only PET images for …

An Approach For Online Assessment Of Rooftop Solar Pv Impacts On Low-Voltage Distribution Networks, Md Jan-E- Alam, Kashem Muttaqi, Darmawan Sutanto
Faculty of Engineering and Information Sciences - Papers: Part A
Assumption-based offline analysis tools may not be able to provide sufficient and accurate information for the corrective decision making to mitigate solar photovoltaic (PV) impacts in the future distribution grids. This is mainly due to the increasing penetration level of intermittent power generation resources and also the fluctuating behavior of consumer demand. Online assessment tools can assist to manage PV impacts and aid to mitigate those on a real-time basis. This paper proposes an approach for online assessment of rooftop PV impacts on low-voltage (LV) networks using real-time network data. A variable-width sliding window will be used to provide the …

Ireland's Tidal Energy Resource: An Assessment Of A Site In The Bulls Mouth And The Shannon Estuary Using Measured Data, Fergal O'Rourke, Fergal Boyle, Anthony Reynolds
Articles
The issues associated with Ireland’s over reliance on fossil fuels to meet energy demands have sparked an interest in renewable energy. Renewable energy resources typically are intermittent and vary significantly in energy intensity. Tidal energy however has the advantage of predictability over large time scales and high power densities. A study of Ireland's tidal-current-energy resource has identified several viable sites. As part of this resource assessment, Acoustic Doppler Current Profilers were installed at two locations along Ireland's west coast, at a site in the Bulls Mouth and the Shannon Estuary. The Acoustic Doppler Current Profilers measured tidal current speed and …

Context-Aware Mobile Augmented Reality Visualization In Construction Engineering Education, Arezoo Shirazi
Electronic Theses and Dissertations
Recent studies suggest that the number of students pursuing science, technology, engineering, and mathematics (STEM) degrees has been generally decreasing. An extensive body of research cites the lack of motivation and engagement in the learning process as a major underlying reason of this decline. It has been discussed that if properly implemented, instructional technology can enhance student engagement and the quality of learning. Therefore, the main goal of this research is to implement and assess effectiveness of augmented reality (AR)-based pedagogical tools on student learning. For this purpose, two sets of experiments were designed and implemented in two different construction …

Recent research in ethics education shows a potentially problematic variation in content, curricular materials, and instruction. While ethics instruction is now widespread, studies have identified significant variation in both the goals and methods of ethics education, leaving researchers to conclude that many approaches may be inappropriately paired with goals that are unachievable. This paper speaks to these concerns by demonstrating the importance of aligning classroom-based assessments to clear ethical learning objectives in order to help students and instructors track their progress toward meeting those objectives. Two studies at two different universities demonstrate the usefulness of classroom-based, formative assessments for improving …
