    Introduction: Patients under the error-prone and complication-burdened extracorporeal membrane oxygenation (ECMO) are looked after by a highly trained, multidisciplinary team. Simulation-based training (SBT) affords ECMO centers the opportunity to equip practitioners with the technical dexterity required to manage emergencies. The aim of this article is to review ECMO SBT activities and technology followed by a novel solution to current challenges. ECMO simulation: The commonly-used simulation approach is easy-to-build as it requires a functioning ECMO machine and an altered circuit. Complications are simulated through manual circuit manipulations. However, scenario diversity is limited and often lacks physiological and/or mechanical authenticity. It is also expensive to continuously operate due to the consumption of highly specialized equipment. Technological aid: Commercial extensions can be added to enable remote control and to automate circuit manipulation, but do not improve on the realism or cost-effectiveness. A modular ECMO simulator: To address those drawbacks, we are developing a standalone modular ECMO simulator that employs affordable technology for high-fidelity simulation.Peer reviewe

    New analytical development in kinematics planning is reported. The INtelligent KInematics Planner (INKIP) consists of the kinematics spline theory and the adaptive logic annealing process. Also, a novel framework of robot learning mechanism is introduced. The FUzzy LOgic Self Organized Neural Networks (FULOSONN) integrates fuzzy logic in commands, control, searching, and reasoning, the embedded expert system for nominal robotics knowledge implementation, and the self organized neural networks for the dynamic knowledge evolutionary process. Progress on the mechanical construction of SRA Advanced Robotic System (SRAARS) and the real time robot vision system is also reported. A decision was made to incorporate the Local Area Network (LAN) technology in the overall communication system

    The Role of Corporate Image and Extension Similarity in Service Brand Extensions

    In this article we examine the role of corporate image in extending service brands to new and traditional markets in the telecommunications sector. With regards to corporate image, service brand extensions are primarily associated with innovation-related attributes, such as order of entry (i.e., pioneers versus followers). Increasingly, firms are extending their services to markets that are beyond the markets that they traditionally have been active in. The results of an experimental study show that consumers evaluate service extensions by providers with an innovative late mover image more favourably that service extensions by companies with a pioneer image in terms of perceived corporate credibility and expected service quality. With regards to these evaluation criteria, it was also found that consumers prefer service brand extensions to related rather than unrelated markets. In addition we find that the relative distance between service providers with an innovative late mover image and pioneers is larger in related markets.marketing ;

    Achieving Corresponding Effects on Multiple Robotic Platforms: Imitating in Context Using Different Effect Metrics

    Original paper can be found at: www.aisb.org.uk/publications/proceedings/aisb05/3_Imitation_Final.pdfOne of the fundamental problems in imitation is the correspondence problem, how to map between the actions, states and effects of the model and imitator agents, when the embodiment of the agents is dissimilar. In our approach, the matching is according to different metrics and granularity. This paper presents JABBERWOCKY, a system that uses captured data from a human demonstrator to generate appropriate action commands, addressing the correspondence problem in imitation. Towards a characterization of the space of effect metrics, we are exploring absolute/relative angle and displacement aspects and focus on the overall arrangement and trajectory of manipulated objects. Using as an example a captured demonstration from a human, the system produces a correspondence solution given a selection of effect metrics and starting from dissimilar initial object positions, producing action commands that are then executed by two imitator target platforms (in simulation) to successfully imitate

    Using tablets for e-assessment of project-based learning

    Get PDF
    Technology is confirmed to be an effective tool for assessment and feedback, in particular for computer-assisted assessment (Irons, 2008; Challis, 2005), producing feedback (Heinrich et al., 2009) and publishing feedback (Bloxham and Boyd, 2007; Denton, 2003; Denton et al., 2008). The arrival of affordable mobile devices has introduced a new means for enhancing the above practices (Fabian and MacLean, 2014; Plimmer and Mason, 2006; Salem, 2013). Student preferences to smart phones and tablet devices steer the technological innovation towards ubiquitous mobile connectivity. Inspired by the benefits of such life and study style, educators have started exploring the use of these technologies. Tablet computers prove to become their preferred choice as they resolve some of the limitations associated with the design, readability and comprehensiveness of the feedback for mobile devices with smaller screens (Strain-Seymour, 2013, Rootman-le Grange and Lutz, 2013). This paper reports how tablets and the Form Connext mobile app have been used for engaging a sample of 300 Business Studies students in in-class online assessment and designing and providing timely comprehensive feedback. The study has followed an action research strategy that is grounded on a continuous and dynamic process of reflection (Carr and Kemmis, 2003) on the effectiveness of assessment of student projects documented electronically through wikis and electronic portfolios. It refines the use of tablets for summative and formative assessment of the project-based learning tasks through three review cycles, each of which incorporated a Reflection and Improvements stage. The experience resulted in enhancement of assessment strategies and contribution to the development of contemporary models of learning through effective assessment and feedback (Carr and Kemmis, 2003). The results of the work confirm that tablet computers are an effective tool in assessing e-materials in larger classes for two primary reasons. Firstly, design of e-forms facilitates rigorous process of reflection and understanding assessment criteria that in turn benefit students when preparing for the assessment. Hence, legible and detailed feedback is produced anytime anywhere with synchronous updates within the marking team. Secondly, students benefit from immediate comprehensive feedback allowing them to reflect on and improve their understanding of subject matters, as well as to engage in discussing specific details of the work that are captured through the form. An unexpected outcome was the enhanced reputation and respect to the tutors amongst students, the triggering of student curiosity and enthusiasm in applying similar approach to their own work. The diffusion for the practice amongst other units and identifying other purposes for which the mobile app could be used are also seen as achievements exceeding the expectations of the project team
