    Further developments in the Taylor 'V' type VAWT concept
    (Pergamon Press, Elsevier, 1986) Robotham, A; Sharpe, DJ; Taylor, DA; Boyle, GA
    This paper describes the development of the Taylor 'V' Type Vertical Axis Wind Turbine (V-VAWT) which was first described at the 1983 ISES Solar Energy Congress in Perth, Australia. The aerodynamic performance prediction model VAWTTAY has been enhanced in VAWTTAY6. Further wind tunnel tests have been carried out using two-bladed models, and two of these are described. These tests have produced results which have demonstrated that power control of the V-VAWT can be achieved by varying the pitch of the blade tips. The design of a prototype 5kW machine, that utilises lightweight, composite blades, and the the continued development of the V-VAWT concept is discussed.

    A unified approach to multivariable discrete-time filtering based on the Wiener-theory
    (Institute of Mathematics ASCR, 1987) Barrett, JF; Moir, TJ
    Several theories of discrete-time optimal filtering are in current use but the relationships between these theories is not always appreciated. By using a slightly modified form of the Wiener theory, a unification of the various methods is obtainable. In the present paper this approach is used to discuss in the multivariable case, instantaneous filtering, one-step delayed filtering, fixed-lag filtering, and prediction. It is shown that the one-step delay filter has a natural feedback structure related to the Kalman filter. The relation of the theory with the Hagander -Wittenma rk filter is also discussed.

    Visual Impact Assessment - There's more to it than meets the eye!
    (Mechanical Engineering Publications Ltd, 1992-03-25) Robotham, AJ; Quilleash, P
    The visual impact of a wind farm is one of the major causes of concern for all current U.K. wind farm projects. Often visual impact is the singlemost important issue on which a planning application is judged. A fair and honest assessment of the visual impact of a wind farm demands the co-operation of the developer, the planning authority, the public, and other interested parties. Visual impact assessment also demands that each individual involved in the planning process make their own judgement, because it is inadequate for this issue to be decided by a single individual.

    Progress in the development of a video-based wind farm simulation technique
    (International Atomic Energy Agency (IAEA), 1992-03-25) Robotham, AJ
    The progress in the development of a video-based wind farm simulation technique is reviewed. While improvements have been achieved in the quality of the composite picture created by combining computer generated animation sequences of wind turbines with background scenes of the wind farm site, extending the technique to include camera movements has proved troublesome

    Knowing the wheat from the weeds in noisy speech
    (International Speech Communication Association (ISCA), 1997) Moir, T; Agaiby, H
    This paper introduces a word boundary detection algorithm that works in a variety of noise conditions including what is commonly called the 'cocktail party' situation. The algorithm uses the direction of the signal as the main criterion for differentiating between desired-speech and background noise. To determine the signal direction the algorithm calculates estimates of the time delay between signals received at two microphones. These time delay estimates together with estimates of the coherence function and signal energy are used to locate word boundaries. The algorithm was tested using speech embedded in different types and levels of noise including car noise, factory noise, babble noise, and competing talkers. The test results showed that the algorithm performs very well under adverse conditions and with SNR down to -14.5dB.

    International collaborative learning - the facilitation process
    (EdMedia, 1999) Clear, Tony
    International collaborative learning is becoming more viable through a variety of Internet enabled software products. Group Support Systems appear to offer promise. But it is not well understood how to facilitate the teaching and learning process in electronic environments. If education is to involve an interactive process of collaborative inquiry and dialogue between remote groups of learners, then designing meaningful learning experiences presents challenges in logistics, technology support, software design, and pedagogy. To better model the facilitation process in such environments, a theoretical framework based on an extension of Adaptive Structuration Theory is suggested. This framework is then related to experiences with custom application software development using Lotus Notes Domino(TM), internal trials and a limited scale collaborative learning exercise between students at Auckland Institute of Technology and Uppsala University. The paper concludes by providing some recommendations for the redesign of the application, suggesting revisions to the collaborative process based on the framework presented, and discussing further extensions to the trials.

    A collaborative learning trial between New Zealand and Sweden - using Lotus Notes Domino in teaching the concepts of Human Computer Interaction
    (ACM, 1999) Clear, Tony
    This paper reports the results of a collaborative learning exercise between students at Auckland Institute of Technology and Uppsala University. The exercise was conducted using both a Lotus Notes Domino collaborative database and electronic mail to support students working in remote groups to perform a common task. Issues concerning the logistics of such an exercise, student participation and evaluations of the process, ethical considerations and the quality of the learning process are discussed. Some conclusions are drawn concerning the value of Group Ware technology to support this form of collaborative learning, and suggestions are made for future developments.

    Knowledge skills and abilities demanded of graduates in the new learning environment
    (NACCQ, 1999) Young, A.; Senadheera, L.; Clear, Tony
    Changes in technology and employer demands require that we regularly survey our stakeholder communities to ensure the relevance and currency of what we are teaching, and the qualifications we offer to prepare our students for practice. At a presentation to an IT breakfast of the NZCS Auckland Branch in October 1998, the audience were surveyed in order to gauge how well we were doing in developing tomorrow's practitioners. Topics surveyed were: the relative importance of different technical skills required by employers, the key trends that we need to prepare graduates for, the impact of the Internet on skills required, the most urgent up skilling requirements of employees and the relative value of vendor vs. formal Polytechnic qualifications. The results of the survey are reported, the key findings analysed and some strategies are suggested which address the identified gaps.

    A framework for product development
    (NTNU/DTU, Technical University of Denmark, 1999) McAloone, TC; Robotham, AJ
    Since the introduction of Integrated Product development in 1985, industry has widely been using this model to understand and articulate their design, business and production activities. Recently, however, the picture has started to alter, as the nature of industry’s business has had to adapt to a much more complex world and in many cases, Integrated Product Development is no longer a sufficient way of describing industry’s product development activity. This paper uses the model of Integrated Product Development as a start-point to exploring the changes that industry has been undergoing over the fifteen years since it was introduced and attempts to make pointers in the direction of a new framework for product development, which should guide industry in the future. The key research challenges that this paper identifies include: developing a framework that identifies and supports a multi-aspect approach to product development; understanding the strategic conditions that affect product development; developing a coherent approach to product quality based on product-life thinking; addressing environmental needs in a proactive manner through innovation techniques; and understanding both organisational and technical knowledge-management for improved product development

    Improving conceptual design quality by use of QFD & DFMA processes
    (WDK, 1999-08-24) Bush, SA; Robotham, A
    This paper will consider how Quality Function Deployment (QFD) and Design for Manufacture and Assembly (DFMA) processes can be used to improve the design quality of products at the concept stage. We appreciate that both QFD and DFMA are techniques that have been used for some time by mature product developers, and the successes achieved using each have been widely reported. Here, though, we will share our experiences of using these tools with novice designers, i.e. student engineers.

    Practitioners of design for quality
    (WDK, 1999-08-24) Robotham, AJ
    Building in high quality continues to be the driving force of new product development activity in industry. Yet as we come to the end of the 1990s and look forward to the challenges in Design Research of the new millennium, Design for Quality does not appear to attract the attention or interest of many design researchers. Importantly, if research attention is not paid to Design for Quality, how can we expect to educate and train future design practitioners to master this critical dimension of product development? The purpose of this paper is to consider the current status of Design for Quality, explore the skills designers require to be effective practitioners of Design for Quality, and to identify some of the challenges the design research community needs to face

    A multi-discipline approach linking related disciplines and stakeholder communities to develop business expertise for the new technological environment
    (Australian Academic Press, 2000) Petrova, K.; Sinclair, R.
    Although teaching institutions are typically well behind business in adopting new technologies, an attempt is being made at the Auckland University of Technology to introduce a new field of study and a new technological environment for its delivery - a comprehensive programme in eBusiness studies. The university works very closely with its stakeholder communities particularly in identifying new programme needs to ensure a balance is achieved between technical skill and business focus. As a result of this collaboration an operational model comprising a total of eight modules was constructed with the aim of integrating the proposed eBusiness qualifications within the structure of an existing Bachelor of Business degree. This paper discusses the background and development of a module called "Electronic Transactions and Security" and the interrelationship between other modules within the eBusiness field of study. The module comprises transaction processing, transaction security and risk management and has evolved into a multi-discipline partnership between the Accounting and Finance and Information Technology business disciplines. New digital technologies - such as on-line collaboration and on-line resource sharing and exchange will be an integral part of the teaching and learning process.

    Dimensions of distance learning for computer education
    (ACM, 2000) Clear, Tony; Meyer, J.; varden, S.; Rugeli, J.
    In this paper, we explore what is variously termed distance learning (DL), asynchronous, online, Web-based, and Web-supported learning in terms of how it can support and perhaps even improve the fields of education involving computing. We use the term distributed education to cover all mentioned topics. We describe how the incorporation of these methods can benefit computer education. These benefits arise because of the nature of the computing field, the profound requirements for students to understand concepts and acquire skills as opposed to mere exposure to facts, and our assessment that distributed education has the potential to address many of the challenges identified. We conclude with suggestions on the incorporation of distributed methods into computer education.

    What is the new paradigm in product quality?
    (Department of Control and Engineering Design, Technical University of Denmark, 2000) Robotham, A; Guldbrandsen, M
    The current product quality paradigm is founded upon a customer-focused product development process, in which the functionality and behaviour of a product are designed to fulfil the needs of customers, and technological innovation is used to expand the capability and enhance the performance of the product. However, this view of product quality does not reflect the current practices of today's leading manufacturers, who now offer "total solutions" based upon an integrated package of products and services with well defined characteristics tailored to individual needs. Concepts such as globalisation, mass customisation, product branding, e-commerce, and sustainability suggest that a new product quality paradigm is evolving. This paper will discuss our current understanding of product quality issues and outline our vision of the new quality paradigm for product developers.

    Using Groupware for international collaborative learning
    (IEEE, 2000) Clear, Tony; Daniels, M.
    The paper reports the lessons learned from a two year collaborative learning trial between students at Auckland University of Technology (AUT) and Uppsala University. The trials took place using a combination of email and a custom developed Lotus NotesTM database. The first trial involved a case study in which students performed different roles in designing a software solution for an Auckland based nailcare distributor. The second trial built upon the knowledge base of the earlier trial, and required students to evaluate and rank the previous design proposals. A theoretical model developed from the group support systems literature guided some of the changes in the second trial. The software, the collaboration process and the evaluation methods evolved over the course of these trials. The challenges of creating global student communities within a short collaboration window in existing courses of study are discussed. Further extensions to this research are proposed and some general recommendations are made

    GPS observations in Thailand for hydrological applications
    (TERRAPUB, 2000) Takiguchi, H; Kato, T; Kobayashi, H; Nakaegawa, T
    We report the delineation of the onset of the Asian Monsoon based on GPS sensing of water vapor in Thailand. We conducted GPS observations at five sites in Thailand since March 1998 under the hydrological project called GAME-T. The objective of the project is to clarify the water and energy cycle system in the Asian Monsoon area. As a preliminary analysis, we used data from March to June 1998 and estimated the water vapor content in the zenith direction (PWV) every 30 minutes using GIPSY software (GPS-PWV). A comparison of the resultant PWV with those estimated from rawinsonde data (Sonde-PWV) suggested that, generally, the long term trends of both GPS-PWV and Sonde-PWV are consistent and a rapid increase of water vapor content is visible in May, which corresponds to the onset of the Monsoon. However, systematic differences between GPS-PWV and Sonde-PWV are eminent. The RMS of the difference (RMSD) between Sonde-PWV and GPS-PWV reaches about 8.7 mm. This large RMSD can be reduced to about 5 mm by removing some unreliable sonde data and making a linear correction to Sonde-PWV. In addition, a comparison of GPS-PWV with other meteorological data (temperature, humidity, and rainfall) showed that there is a strong correlation between a rapid increase of GPS-PWV and heavy rainfall in Bangkok and in Chiang Mai, which may be used to judge the onset of the Monsoon in the area accurately.
