Establishing A Project Based Learning Environment For First Year Engineering Students, Brad Stappenbelt
Establishing A Project Based Learning Environment For First Year Engineering Students, Brad Stappenbelt
Faculty of Engineering - Papers (Archive)
A project-based learning environment was recently established for first-year engineering students at the University of Western Australia. At the focus of this educational approach was a real international development project run within the core undergraduate unit Introduction to Professional Engineering. Students embarking on the professional development component of the engineering degree were traditionally taught about the role of the engineer, social and cultural engineering considerations, the multi-disciplinary nature of large engineering projects and team working and communication skills with minimal involvement in project and group work. The various concepts covered were treated primarily on an abstract theoretical level. Despite the …

This paper considers a hybrid maintenance policy for a single component from a heterogeneous population. The component is placed in a socket, and the component and socket together comprise the system. The s-population of components consists of two sub-populations with different failure characteristics. By supposing that a component may be in a defective but operating state, so that there exists a delay time between defect arrival and component failure, we consider a novel maintenance policy that is a hybrid of inspection and replacement policies. There are similarities in this approach with the concept of ldquoburn-inrdquo maintenance. The policies are …

This paper examines the implementation of a project-based learning approach in the first year engineering curriculum at the University of Western Australia (UWA). As part of this initiative, the Engineers Without Borders (EWB) Challenge was employed as the focus of student activity within the core undergraduate unit Introduction to Professional Engineering. This unit is the foundation of the professional development component of the engineering degree at UWA. The EWB Challenge provided students with the opportunity to learn about professional engineering whilst contributing towards a real international development project. To create a successful project based learning environment, a comprehensive tutor training …
A Bio-Inspired Robotic Locomotion System Based On Conducting Polymer Actuators, Gursel Alici, Daniel Gunderson
A Bio-Inspired Robotic Locomotion System Based On Conducting Polymer Actuators, Gursel Alici, Daniel Gunderson
Faculty of Engineering - Papers (Archive)
This paper presents the conceptual design and testing of a bio-inspired locomotion system activated through ionic-type conducting polymer actuators, which can operate both in dry and wet environments. The locomotion system is proposed for a mini autonomous crawling device for applications typified by pipe inspection, search, inspection and data gathering in confined spaces, which require mini-robotic systems. The locomotion system is based on the cilia, which has a simple planar bending motion. This type of motion can be provided by bending-type polymer actuators (one-end fixed and the other-end free cantilever beam). The actuators mounted on a printed circuit board and …
A Method To Design Transmission Resonances Through Subwavelength Apertures Based On Designed Surface Plasmons, Jinsong Liu, Lan Ding, Kejia Wang, Jianquan Yao
A Method To Design Transmission Resonances Through Subwavelength Apertures Based On Designed Surface Plasmons, Jinsong Liu, Lan Ding, Kejia Wang, Jianquan Yao

A plasmonic metamaterial is proposed for which an array of subwavelength apertures is pierced into a metallic foil whose one flat surface has been made with periodic rectangle holes of finite depth. Designed surface plasmons sustained by the holes are explored when the size and spacing of the holes are much smaller than those of the apertures. The transmission property of electromagnetic waves through the metamaterials is analyzed. Results show that the designed surface plasmons characterized by the holes could support the transmission resonances of the incident wave passing through the subwavelength apertures, and that the peak transmission wavelengths could …
A Comparative Study On Field, Temperature, And Strain Dependences Of The Critical Current For Doped And Undoped Mgb2 Wires Based On The Percolation Model, Sangjun Oh, Jung Ho Kim, Kyuhwan Cho, Chulhee Lee, Chan-Joong Kim, S. X. Dou, M Rindfleisch, Mike Tomsic, Jung-Ho Ahn

Field, temperature, and strain dependences of the critical current for a SiC doped multifilamentary in situ MgB2 wire have been studied. Measurement results were compared with that of the undoped wire, and the origin of the difference in the critical current is discussed. The critical current can be calculated with the percolation model considering the effect of anisotropy. The temperature dependence of the fitting parameters, the upper critical field along the ab-plane, and c-axis is compared with the dirty-limit two-gap theory. To assess the validity of the fitting parameters, resistive transition has been measured especially to …
