    BOLLOCKS!! Designing pervasive games that play with the social rules of built environments

    We propose that pervasive games designed with mechanics that are specifically in opposition with, or disruptive of, social rules of the environment in which they are played, have unique potential to provide interesting, provocative experiences for players. We explore this concept through the design and evaluation of an experimental game prototype, Shhh!, inspired by the juvenile game Bollocks, and implemented on Android mobile devices, which challenges players to make loud noises in libraries. Six participants played the game before engaging in semi-structured interviews, explored through inductive thematic analysis. Results suggest that the game provoked in players a heightened awareness of social rules, as well as a complex social dilemma of whether or not to act. We conclude by presenting a model for designing games that play with the social, as well as physical, rules of the environments in which they are set

    Indirect angle estimation in switched reluctance motor drives using fuzzy logic based motor model

    Copyright © 2000 IEEEIn this paper, a novel rotor position estimation scheme is described that was developed to overcome the drawbacks of the previous sensorless techniques, which were proposed for switched reluctance (SR) motor drives. It is based on fuzzy-logic, and does not require complex mathematical models or large look up tables. The scheme was implemented by using a digital signal processor. The real-time experimental results given in this paper show that the position estimation method proposed can provide accurate and continual position data over a wide range of speeds (zero/low/high), and can also function accurately at different operating conditions (chopping/single pulse mode and steady state/transient operation).Nesimi Ertugrul and Adrian D.

    High robustness and reliability of fuzzy logic based position estimation for sensorless switched reluctance motor drives

    Get PDF
    Copyright © 2000 IEEEIn many applications where motor drives are used, concern. Thus, a major consideration is the reliability of position estimation schemes when sensor less SR motor drive control is employed. Hence, in this paper, the robust of a fuzzy logic based angle estimation algorithm for the switched reluctance motor (SR) motor is described. It is shown using theoretical analysis and experimental results, that by using logic, the angle estimation scheme gains a high level of robustness and reliability. A theoretical and quantitative analysis of the noise and error commonly found in practical motor drives is given, and how this can affect SR motor position estimation. An analysis is also given on the concepts of robustness and reliability. It is shown that the fuzzy logic based scheme is robust to erroneous and noisy signals commonly found in motor drives.Adrian David Cheok and Nesimi Ertugru

The measuring scheme was developed using a graphical programming environment (LabVIEW), a data acquisition card, and external interface hardware. The graphical programming method allows a high degree of software modularity and provides the features needed for sensor zero adjustment, data acquisition and analysis, and automated presentation of results. Furthermore, the experimental setup described in this paper can be used to obtain the magnetization characteristics of other electromechanical devices. Experimentally measured results from a test SR motor using the scheme are presented in the paper.Adrian David Cheok and Nesimi Ertugru

    Importance of branding property developers in Malaysia

    Get PDF
    This paper aims to study the brand consciousness of property purchasers in Malaysia. This study is based on a survey of purchasers in Klang Valley on the brand awareness and the brand personality traits of property developers. 5000 questionnaires were distributed and finally 214 were used for this study. The results show that property purchasers are brand conscious in relation to the property developers and they ranked developers based on the brand personality. Property purchasers look at trend, professionalism and investment as the top 3 priorities in the property brand. The conclusion is that all property firms, designers, real estate agents and stakeholders who?that are involved in property development are to ensure that their products are designed with brand consciousness in mind. The findings in this paper suggest that property designers should pay attention to trend in the property development, property marketers should be professional in dealing with purchasers and the developers should ensure good locations for property investments

    Evaluation of Some Long Bean Lines Using Early and Late Produced Seeds in Two Soil Types

    Get PDF
    Early and late produced seeds of some F9 lines and exotic cultivars of long beans were evaluated on clayey loam and alluvial soil in the University Farm at Serdang. The results showed that pod yield and pod length were not significantly different for seeds produced early or late. Among the genotypes studied, pod yield was more unstable than pod length. However, some lines and Taiwan Stripe Seed performed better than the ,local commercial variety, Local Long-l in both soil types
