A Configurable Matchmaking Framework for Electronic Marketplaces

E-marketplaces constitute a major enabler of B2B and B2C e-commerce activities. This paper proposes a framework for one of the central activities of e-marketplaces: matchmaking of trading intentions lodged by market participants. The framework identifies a core set of concepts and functions that are common to all types of marketplaces and can serve as the basis for describing the distinct styles of matchmaking employed within various market mechanisms. A prototype implementation of the framework based on Web services technology is presented, illustrating its ability to be dynamically configured to meet specific market needs and its potential to serve as a foundation for more fully fledged e-marketplace frameworks

Jeeva: Enterprise Grid-enabled Web Portal for Protein Secondary Structure Prediction

This paper presents a Grid portal for protein secondary structure prediction developed by using services of Aneka, a .NET-based enterprise Grid technology. The portal is used by research scientists to discover new prediction structures in a parallel manner. An SVM (Support Vector Machine)-based prediction algorithm is used with 64 sample protein sequences as a case study to demonstrate the potential of enterprise Grids.Comment: 7 page

Towards solutions for assistive technology

Introduction What is assistive technology? The agreed World Health Organisation definition is "Assistive technology can be defined as “any piece of equipment, or product, whether it is acquired commercially, modified, or customized, that is used to increase, maintain, or improve the functional capabilities of individuals with disabilities” (WHO, 2011) The array of possible assistive technology products and solutions reflects the diversity of the needs of people with disabilities – ranging from digital technologies that can support social engagement, communication, employment, learning, memory, planning and safe guarding services through to products and devices that support mobility and personal care requirements. Typically as the complexities of assistive technology solutions increase, so do the costs and potential risks (if not appropriately set up or maintained). This document is primarily focused on the Assistive Technology solutions derived from aids and equipment. Home and vehicle modifications and prosthetics have not yet been explored in the same level of detail and will be subject of further work. Proposed approach The proposed assistive technology service approach has been developed in line with the strategic goals of the NDIA. It is one aspect of a broader strategic approach the NDIA has to using technologies to enhance its engagement and management of relationships, services and supports with suppliers, providers, participants and the Australian community. The NDIA’s goal is to use technology in its various forms to ensure that services, supports, and communications between all stakeholders are as streamlined as possible and services are timely and effective. This document outlines the elements of a proposed service delivery approach for individuals to access assistive technology solutions and is based on the three key objectives outlined above

Automated software quality visualisation using fuzzy logic techniques

In the past decade there has been a concerted effort by the software industry to improve the quality of its products. This has led to the inception of various techniques with which to control and measure the process involved in software development. Methods like the Capability Maturity Model have introduced processes and strategies that require measurement in the form of software metrics. With the ever increasing number of software metrics being introduced by capability based processes, software development organisations are finding it more difficult to understand and interpret metric scores. This is particularly problematic for senior management and project managers where analysis of the actual data is not feasible. This paper proposes a method with which to visually represent metric scores so that managers can easily see how their organisation is performing relative to quality goals set for each type of metric. Acting primarily as a proof of concept and prototype, we suggest ways in which real customer needs can be translated into a feasible technical solution. The solution itself visualises metric scores in the form of a tree structure and utilises Fuzzy Logic techniques, XGMML, Web Services and the .NET Framework. Future work is proposed to extend the system from the prototype stage and to overcome a problem with the masking of poor scores

Lifeguard: Local Health Awareness for More Accurate Failure Detection

SWIM is a peer-to-peer group membership protocol with attractive scaling and robustness properties. However, slow message processing can cause SWIM to mark healthy members as failed (so called false positive failure detection), despite inclusion of a mechanism to avoid this. We identify the properties of SWIM that lead to the problem, and propose Lifeguard, a set of extensions to SWIM which consider that the local failure detector module may be at fault, via the concept of local health. We evaluate this approach in a precisely controlled environment and validate it in a real-world scenario, showing that it drastically reduces the rate of false positives. The false positive rate and detection time for true failures can be reduced simultaneously, compared to the baseline levels of SWIM

The Theological Principles Underlying Parish Records with Particular Application to their Role in the Design and Evaluation of Computer Software

This paper will document the theological and pastoral underpinnings of LCIS and its immediate successors as a reminder that how we say things and what we do should flow from what we believe. However, these theological and pastoral considerations have more than historical importance. For, although the forms and programs congregations use to keep their records may change, unless our beliefs change, the principles behind their selection and use will remain the same. Clarifying these principles should be helpful to those who wish to understand how they can best utilize their current system for keeping records. Understanding them will help congregations that are selecting new software to pick something that will work well for them, both theologically and practically, so that the software will be a help rather than a burden in their service to Christ’s kingdom. Finally, since many newer programs allow users to adjust their terminology, these pages will provide guidance as to the sorts of terminology that would be most appropriate
