Mantis Shrimp Capture Technique.m4v
No full textThis short video was taken by Diarmaid Ó Foighil in the Indian River Lagoon (Florida) and it demonstrates the bait-and-capture technique (Goto et al., 2018) used by first author Teal Harrison* to collect Lysiosquilla scabricauda specimens. A bait fish was placed directly over a submerged host mantis shrimp burrow opening and once a resident emerged, its raptorial appendages were sequentially grasped by hand and, as it tired, the specimen was slowly pulled upward out of its burrow.*Teal A.

‘Centering’ Teaching Excellence in Higher Education
No full text[EN] This paper explores the complexity of ‘teaching excellence’ (Kreber, 2002) in contemporary higher education. It describes how a university academic, who has been the recipient of numerous teaching awards, questions if they really are an ‘excellent teacher’ and if their student-centered philosophy is sustainable. An analysis of data related to teaching and learning effectiveness over a seven year period highlights a significant weakness in how the academic approached the teaching of undergraduate students. This had a subsequent negative effect on several levels. The paper concludes by describing the merits of academics ‘centering’ themselves between the corporate university and the needs of students in striving for ‘teaching excellence’.Lane, D.

Collision Avoidance using Lane Departure Warning and Obstacle Determination in the Automotive Environment
No full textStatistics show that worldwide motor vehicle collisions lead to significant death and disability as well as significant financial costs to both society and the individuals involved. This thesis aims to address this issue by proposing a system for the detection of lane departures and obstacles, two of the leading causes of road fatalities by collisions. Awareness of the environment that surrounds a vehicle can make driving and manoeuvring of the vehicle much safer for all road users. The primary focus of this thesis is the development of an image processing system to detect lane departure using a single, forward facing visible spectrum camera. This system uses a novel lane marking segmentation algorithm in accordance with national standards for lane markings and identifies lane departure using guidelines issued by the International Organisation for Standardization. Issues with a single camera-based LDW system can arise when other road users occlude the field of view of the sensor, or by glare from oncoming headlamps and bright sunlight on the sensor. To address these problems, a lane departure warning system that utilises multiple cameras is also presented. This multi-camera system is more robust to errors caused by lane marking occlusions, sensor failure, and glare that a single camera-based system can suffer from. Object detection is a large area of research in the field of automotive technologies. By displaying the surroundings of the vehicle and the included objects to the driver in a useful and intuitive way, this aids the driver to safely manoeuvre the vehicle. Similarly, warning the driver of potential obstacles in the trajectory of the vehicle reduces the probability that the vehicle will be in a collision. An examination of the state of the art in object detection and distance determination technologies is presented and from analysis of the limitations in existing systems, a number of novel obstacle detection/distance determination systems are also proposed in this thesis. Overall, this research aims to reduce the number of vehicle collisions and contribute to a safer driving environment

Developing sketching expertise within technology education
No full textAt a time when technological capabilities are perceived to be critical in redefining effective technological education, the introduction of Design and Communication Graphics (DCG) in Irish second level (high) schools has broad implications. Students now have the potential to explore applied geometries, integrated with conceptual thinking in addition to developing essential communication skills. Central to this development is the ability to freehand sketch.
Literature concerning freehand sketching (Verstijnen, 1998b) claims that there is a lack of empirically validated models of instruction which promote the development of sketching ability. This research study set out to explore if it was possible to develop the ability to freehand sketch through appropriate instruction and empirically evaluate any development.
The study was carried out within Initial Technology Teacher Education (ITTE) and involved over 270 undergraduate students. A number of preliminary studies were carried out to address deficiencies identified in the literature relating to freehand sketching. Using a pre and post test design, the study applied a model of sketching activities which ranged along a continuum from observation to imagination. The effectiveness of the model was examined using various methods (such as visual and verbal protocols (Middleton, 2008)) which captured the tacit and implicit nature of sketching behaviour and cognition.
The application of Comparative Pairs (Kimbell, 2008) as an assessment tool for pre and post-instruction conceptual sketches provided a novel method of measuring improvement. It was found that students sketching ability significantly improved as a result of completing the model of activities. The magnitude of improvement was dependent on a number of factors including motivation and previous learning experiences. The model of activities was effective in promoting the ability to use sketching as a communication and problem solving tool. It was found that the model of activities could be delivered by independent teachers. A number of findings relating to students sketching behaviour and cognition were correlated with literature associated with sketching expertise.
The study concludes that freehand sketching skill can be developed through appropriate instruction. An empirically tested model of instruction which promotes sketching ability was designed and validated. This has significant implications for the development of pedagogies within Design and Communication Graphics (DCG) and other technology subjects
