Large-scale biological sequence assembly and alignment by using computing grid

Large-scale sequence assembly and alignment are fundamental parts of biological computing. However, most of the large-scale sequence assembly and alignment require intensive computing power and normally take very long time to complete. To speedup the assembly and alignment process, this paper parallelizes the Euler sequence assembly and pair-wise/multiple sequence assembly, two important sequence assembly methods, and takes advantage of Computing Grid which has a colossal computing capacity to meet the large-scale biological computing demand.

Access and attitude of rural allied health professionals to CPD and training

Continuing professional development (CPD) activities for allied health professionals are becoming mandatory as a means for professionals to maintain accreditation or skills. To access CPD activities, rural allied health professionals have the added costs of travel, accommodation and information technology access. It is assumed that health professionals in rural areas want access to training and CPD. In 2003, a survey of allied health professionals was carried out in Southwest Victoria, Australia, with the aim of identifying access and attitudes to CPD. Results showed that allied health professionals in Southwest Victoria were highly qualified, wished to access CPD more than four times a year and were prepared to spend a mean rate of $1000 (1300) per annum on CPD activities.

One to one eMarketing strategy alignment: five internet case studies

Despite widespread adoption of new online business models and the rise of online or eMarketing using the Internet (Net) and its current graphical face the World Wide Web (Web), there remains a need for empirical research into specific aspects of eMarketing strategy beyond clickthrough analysis, Web audience analysis and scrutiny of Websites properties to mention the most widely examined elements. This paper discusses Peppers and Rogers (1999) OnetoOne strategy matrix and synthesises their approach with a series of personal interviews with business managers, drawn from a broader empirical study. It does so in an endeavour to improve outcomes from eMarketing strategy and the use of individual Net technologies. The aim is to aid both business practitioner and academician alike in further improving the effectiveness and efficiency gained from using converging technologies in eBusiness.

An exploratory investigation of attitude toward the website and the advertising hierarchy of effects

The paper discusses the findings of a study designed to increase the generalisability, validity and reliability of earlier studies concerning the relationships between attitude toward the ad and aspects of the advertising hierarchy of effects model in the online marketing context. The findings suggest that the traditional advertising hierarchy of effects model is relevant in the online marketing environment, and that investment in online marketing communication can be evaluated using this stable and reliable method. It is, however, suggested that further research is needed to improve the generalisability of the findings.

Robust terminal attitude navigation for autonomous vehicles

Here we define the terminal attitude of the pursuer with respect to a target and present a LQR and H¿ control approach to solving the problem of pursuer achieving a desired terminal attack/approach angle. The intercept or engagement criteria is defined in terms of both minimizing the miss distance and controlling the pursuer's body attitude with respect to the target at the terminal point. This approach in comparison to previous approaches consider the relativistic approach of the pursuer with respect to the target as opposed the absolute velocities of the two dynamic bodies, and have possible applications ranging from autonomous vehicle entry in to a mother craft to nossle engagements in on-flight refuelling or even in precision missile guidance. Here we also suitably formulate the H¿ control ideas directly applicable to the underlying problem and presents both state feedback and output feed back results for the case of finite horizon and non-zero initial conditions together with a optimal parameter value to achieve a desired terminal characteristic in terms of the original weighting parameters.

The impact of communications and understanding on the success of business/IT alignment

This article reports on an investigation of IS stakeholders communication and mutual understanding, and their impact on the success of business / IT alignment. In particular, by following a hermeneutic study of transcripts of two focus groups and several interviews conducted with senior business and IT executives, the paper explores the issues of modern business context and practices, project scope and structure, trust, language and nomenclature, and the barriers to the effective stakeholder communication and  understanding. The study results are finally compared against the standard model of business and IT alignment. The main unexpected finding being executives' pre-occupation with issues of "marginal" value to the alignment model, such as day-to-day management of communicative and understanding effectiveness, as opposed to the fundamental issues of strategy and infrastructure fit.

Community-based study on knowledge, attitude and practice on the mode of transmission, prevention and treatment of the Buruli ulcer in Ga West District, Ghana

Buruli ulcer disease (BUD), a devastating tropical disease caused by Mycobacterium ulcerans, occurs in more than 80% of the administrative districts of Ghana. To elucidate community perceptions and
understanding of the aetiology of BUD, attitudes towards Buruli patients and treatment-seeking behaviours, we conducted a survey with 504 heads of households and seven focus group discussions in Ga West District, Ghana. Although 67% of participants regarded BUD as a health problem, 53% did not know its cause. Sixteen per cent attributed the cause to drinking non-potable water, 8.1% mentioned poor personal hygiene or dirty surroundings, and 5.5% identified swimming or wading in ponds as a risk factor. About 5.2% thought that witchcraft and curses cause BUD, and 71.8% indicated that BU sufferers first seek treatment from herbalists and only refer to the hospital as a last resort. The main
reasons were prospects of prolonged hospital stay, cost of transport, loss of earnings and opportunity associated with parents attending their children’s hospitalization over extended period, delays in being
attended by medical staff, and not knowing the cause of the disease or required treatment. The level of acceptance of BUD sufferers was high in adults but less so in children. The challenge facing health workers is to break the vicious cycle of poor medical outcomes leading to poor attitudes to hospital treatment in the community. Because herbalists are often the first people consulted by those who contract the disease, they need to be trained in early recognition of the pre-ulcerative stage of Buruli lesions.

Fuzzy terminal attitude guidance controller with angle only measurements

This paper introduces the concept of terminal attitude guidance as an alternative to precision guidance and uses fuzzy control ideas in designing a control strategy for a pursuer in countering a manoeuvreing target. The fuzzy controller uses only angle measurements in the control strategy and produces satisfactory results in comparison to the LQR or H∞ type guidance controllers, although they were addressed in a precision guidance context. Both 2D and 3D cases have been considered.

On an alignment condition of the weyl tensor

We generalize an alignment condition of the Weyl tensor given by Barnes and Rowlingson. The alignment condition is then applied to Petrov type D perfect fluid spacetimes. In particular, purely magnetic, Petrov type D, shear-free perfect fluids are shown to be locally rotationally symmetric.

Knowledge enhancement in the change process : social marketing and attitude change leading to improved environmental behaviour

The complexity of relationships between social change and natural resource management has generated interest in the identification of indicators that might provide more streamlined means of monitoring and planning control programmes. This case study highlights the marketing paradigms of benchmarking and social marketing in a not-for-profit governmental environment. Publicly funded programs that require individual and community participation need to be marketed with a view to optimising involvement and commitment of the various stakeholders. A mail survey with a representative sample of 608 respondents was conducted to evaluate the effectiveness of a social marketing program. This study highlights the use of social marketing in a program to overcome an environmental issue by a governmental agency. Changing attitudes and beliefs takes time and often the target audience may not even know they have a problem that needs fixing. This process influences the focus of the social marketing effort which might be organised into three phases: • Raise awareness and knowledge.   •Change attitudes.  • Encourage action. The research conducted in this study illustrates how the various stages in the social marketing process were achieved through knowledge enhancement in an environmental management case study.

On rapid vector alignment in permanent magnet brushless motor

A software replacement for the commutation signals of a permanent magnet brushless motor is presented. The feedback observed acceleration loop or equivalently the high-order position polynomial controller allows finding the initial relative orientation between the two magnetic fields of the motors within a fraction of a second. Also, using the proposed method allows a considerable cost saving, since the transducer that is usually used for this purpose can be eliminated. The cost saving is most obvious in the case of linear motors and angle motors with large diameters. The way the problem is posed is an essential part of this work and it is the reason behind the apparent simplicity of the solution. The method has been tested when a relative encoder was used and the motor current was regulated.
