Which gates are universal for quantum computation? Although it is well known that certain gates on two-level quantum systems (qubits), such as the controlled-not, are universal when assisted by arbitrary one-qubit gates, it has only recently become clear precisely what class of two-qubit gates is universal in this sense. We present an elementary proof that any entangling two-qubit gate is universal for quantum computation, when assisted by one-qubit gates. A proof of this result for systems of arbitrary finite dimension has been provided by Brylinski and Brylinski; however, their proof relies on a long argument using advanced mathematics. In contrast, our proof provides a simple constructive procedure which is close to optimal and experimentally practical. © 2002 The American Physical Society.

Simulations and universal quantum computations using an entangling Hamiltonian and local unitaries were performed. A specific two-qubit example was given to illustrate the techniques and the general algorithm was described for the case of an arbitrary two-qubit systems. The efficiency of the algorithm and the effect of errors were then discussed.

The paper reports the outcomes of one module of a collaborative learning project aimed at the development of leadership capacity in district health management teams in the East Cape province of South Africa. A work‐based learning methodology was selected for the module with the intention of developing strategic and procedural knowledge bases within these teams as a way of addressing the complex problems of policy implementation in South African state organisations. The paper demonstrates the effectiveness of collaborative work‐based projects in developing team members’ capacity to solve difficult workplace problems and to implement strategy in a challenging operational environment. It endorses the role of leadership coaching in the development of, and ability to leverage, important strategic knowledge resources that reside within and between team members. The paper concludes with an example that demonstrates the developing ability of team members to initiate successful collaboration around the resolution of complex service delivery problems.

In this paper, a novel edge-oriented neural-network-based adaptive interpolation scheme for natural image is proposed. An image analysis module is used to classify pixels of the input image into non-oriented class and oriented class. The bilinear interpolation is used to interpolate the non-oriented regions and a neural network is proposed to interpolate the oriented regions. High-resolution digital images along with supervised learning algorithms can be used to automatically train the proposed neural network. Simulation results demonstrate that the proposed new resolution enhancement algorithm can produce higher visual quality of the interpolated image than the conventional interpolation methods.

The main barriers to the level of electronic data interchange required to seamlessly integrate services offered by legacy systems in an Internet environment are the need for applications to share a common data definition and the non-heterogeneity in database platforms. This paper details a collaborative research initiative between the Penrith City Council, Penrith Australia and the Centre for Advanced Systems Engineering (CASE) at the University of Western Sydney. It details the development of a fully functioning XML-based prototype system that provides effective integration of services offered by a collaborating group of legacy systems. The key contribution of this work is to provide an open systems based infrastructure that allows collaborating legacy systems, based on heterogeneous database and server platforms, to offer an integrated query service over the Internet.

© 2002 IEEE. This paper describes an industrial experience in process improvement at one of the Unisys development labs in Australia. Following a Capability Maturity Model (CMM) mini-assessment, the organization is undertaking significant changes in the requirements management process, which include the introduction of group session approaches to requirements analysis and a structured method for writing requirements. An empirical evaluation of the process improvement indicates tangible benefits as well as perceived long-term benefits during design and testing. Findings suggest that a more thorough requirements analysis results in more clearly defined, better understood and specified requirements, and an enhanced ability to address the market needs and product strategy requirements. The catalyst behind these improvements includes project management leadership, managing the human dimension, collaboration among stakeholders and senior management support.

Architecture is a central concept in the engineering of computer based systems. Given a standard architectural representation, the architecture of systems can be discussed, drawn, reasoned about and classified. Complex architectures may benefit from visualisation. Currently, tools that visualise architectures do so in two-dimensions. Above and beyond visualising the form (or structure) of the architecture in three dimensions, other characteristics of the architecture (e.g. Modularity, Performance, Evolvability, and Openness) can be shown through the visualisation. This paper focuses on the "drawing" of architectures or what is referred to as Architectural Visualisation.

© Springer-Verlag Berlin Heidelberg 2002 Use-case modelling provides a means of specifying external features of a system during requirements elicitation. In principle, use cases can be used to size the system about to be built but, for that, a standard format for their documentation is required. Furthermore, gathering use-case metrics requires a software development process that produces complete use-case descriptions in a repeatable way. Here, we set out the requirements for such a standardization so that use cases can be metricated. Once accomplished, it is possible to evaluate the important research questions of whether use-case attributes such as size and complexity can be controlled and whether use-case metrics are sufficiently rigorous for estimating effort. Finally, we note that this added rigour applied to use cases should improve the consistency and quality of communication between client and developer, helping to ensure that the right system is built.

Formalising a measurement is often preceded by rich discussion of the ideas, and the development of general understanding of the meaning of concepts, often over decades. As a consequence, data required to fit into a representational measurement system is usually readily available and there is a general acceptance of the intention of the measure. This paper reports on a research project which has formalised the measurement of a relatively new body of knowledge, open systems. Open systems rely on standards to guarantee interoperability, portability, scalability and user portability. The Internet is the most successful of the open systems in existence, in terms of interoperability and scalability. The first of four issues was that since the project was a research contract, and because there were very few generally understood notions of measurement foundations (or relations) within open systems, the aims and the requirements of the measurement were formalised into a measurement requirements specification (MRS). A second issue concerns the building of a relational model. Building relations in a representational measurement model is relatively straightforward in the case where the measurement entity has been around. A third issue concerned the use of the measures when the measures were (not surprisingly) complex, and had to be combined by biased combiners, the values of which not all parties would naturally agree. A fourth issue raised in the paper is the extent of the validation of the measures which was required because of the contract.

© 2002 IEEE. Organizations invest in B2B and workflow management systems to enable seamless integration of multiple transaction systems that support their business processes. However, knowledge of the organization's performance becomes buried within internal processing of the B2B workflow platform. This research introduces a framework that analyses workflow audit logs, utilizing DSS principles together with agent technologies, to feedback the organization's performance measures. We apply this framework to a private trading exchange case study where suppliers participate in an interorganizational order fulfillment workflow. Agents refine the organization's knowledge of supplier productivity and commitment as they learn from interactions over time with trading partners.

Organisations are re-engineering their B2B communications to be performed through web services. Their aim is to create modularised services that support the business processes within their organisation and also those external entities that participate in these same business processes. This improvement is at the expense of the organisation's knowledge of its performance, as this knowledge will become buried within the internal processing of the web service platform. This research introduces an approach to reclaim and improve this knowledge for the organisation by establishing a framework that enables the definition of web services, together with the logging and analysis of the enactment of web services. This framework utilises web service concepts, DSS principles, and agent technologies, to enable feedback on the organisation's performance measures through the analysis of the web services. We apply this framework to a specific case study where suppliers participate in an inter-organisational workflow via a Private Exchange in the context of order fulfilment. A key benefit of this work is that the data is stored once but provides information both to the organisation acting as the customer and the organisation acting as the supplier. It therefore removes the need for development of internal performance monitoring tools to monitor web services performance.

Neonatal intensive care units (NICUs) require equipment and facilities to assist and monitor premature (and some full-term) babies. This equipment outputs physiological and clinical data, but current research does not provide doctors with techniques for capturing this data in a format that is suitable for analysis and research. Additionally, regional hospitals provide limited NICU support, but, without access to a neonatologist, the baby must be moved to another hospital. This paper details a framework for clinical and physiological data capture, the storage structures within the e-Baby data warehouse, and information access through a secure intranet/Internet browser. The key contribution of this work is the infrastructure that provides a platform for patient information data capture, storage, display and analysis. A key benefit of this work is to provide a mechanism for neonatologists to receive information directly from a regional hospital, thereby preventing, in some cases, the immediate need to move the baby.

© 2002 IEEE. Software development is considered to be a dynamic process where demands for changes seem to be inevitable. Modifications to software are prompted by all kinds of changes including changes to the requirements. This type of changes gives rise to an intrinsic volatility, which has several impacts on the software development lifecycle. This paper describes our findings of an extensive survey based empirical study of requirement volatility (RV) and its impact on software project performance. In particular, findings reveal that requirement volatility has a significant impact on schedule overrun and cost overrun in software projects. Our investigation also examined factors that contribute to the extent of requirement volatility and found that variables such as frequent communications between users and developers and usage of a definable methodology in requirements analysis and modeling have impact on the stability of requirements.
