An Atm System Model And Wireless Channel Simulation, Karen Dunne
An Atm System Model And Wireless Channel Simulation, Karen Dunne
Masters
Congestion in the low frequency regions of the electromagnetic spectrum and demand for support of high bandwidth applications has prompted widespread investigations into networking technologies and communications media. Traditional networking technologies such as Ethernet that are not capable of adequately supporting high bandwidth applications (e.g. videoconferencing) are being replaced by high speed, high bandwidth technologies such as Asynchronous Transfer Mode (ATM). In the communications media market, wireless systems are becoming ubiquitous due to their ease of installation and maintenance costs. In this research, the networking technology of interest is ATM. ATM used a cell switching architecture that allows seamless support …

Usability is a significant factor in the creation of quality software products which is an important focus of the software engineering syllabus. Usability is also a significant factor in the study of Human-Computer Interaction (HCI). Despite the connection, software quality and the rigours of the software engineering discipline are not used in the teaching of HCI and visa versa. Consequently, students undertaking software engineering courses are not fully exposed to usability issues and HCI students often miss out on the disciplines of software engineering. This paper presents a quality focused conceptual model - the Software Quality Star - which can …
An Investigation Into The Causes And Effects Of Legacy Status In A System With A View To Assessing Both Systems Currently In Use And Those Being Considered For Introduction, Patricia O'Byrne
Other resources
This dissertation analyses the area of legacy systems and determines the effects that are exhibited in legacy systems, presenting them in a legacy effect determination framework, so that management can ascertain whether the system they have is a legacy system. An analysis of legacy causal criteria is carried out, resulting in a table of legacy causes. A new definition of legacy systems is put forward, by defining legacy status as a status held by a legacy system. “A system exhibits legacy status if it is deficient in terms of its suitability to the business, its platform suitability or application software …

Using Xml To Network Distributed Analytical Instruments: Back To The Future?, Benjamin Jung, Damon Berry, Jane Grimson
Conference Papers
There has been a paradigm shift in medical informatics standards in recent years from the message-oriented approach to a more distributed systems approach. However, despite all the early promise of distributed applications, they haven't been widely adopted in the health domain for various reasons. As a result, despite an increasing need for a standardised distributed solution for analytical laboratory instruments, many implementers of instrument interfaces are still using proprietary serial interfaces which do not support distribution. The emergence of the eXtended Markup Language (XML) specification in 1998 revived the fortunes of the messaged oriented methodology. This paper presents a partial …
A Process For Appraising Commerical Usability Evaluation Methods., Ronan Fitzpatrick, Alan Dix
A Process For Appraising Commerical Usability Evaluation Methods., Ronan Fitzpatrick, Alan Dix
Conference papers
Recent international quality standards and European Community legislation have identified new software quality factors. These new factors include suitability, installability and adaptability. Other quality factors need to be reviewed in the light of these developments. This has impacted on established commercial usability evaluation methods to the extent that it is appropriate to ask if these evaluation methods comply with the new standards and legislation. In order to answer this question the commercial evaluation methods need to be appraised (meta-evaluation) using a suitable method appraisal process. This paper describes such an appraisal process which specifically addresses the many considerations raised by …
Strategies For Evaluating Software Usability, Ronan Fitzpatrick
Strategies For Evaluating Software Usability, Ronan Fitzpatrick
Articles
This paper presents a usage analysis and taxonomy of methods which are used to evaluate the usability of computer systems. To accommodate the analysis and taxonomy, a matrix of strategies which can be used for effective usability evaluation is presented. Such an analysis, taxonomy and strategies support human-computer interaction (HCI) professionals who have the responsibility for ensuring computer system usability. The strategies outlined are named Virtual Engineering, Soft Modelling, Hard Review and Real World. This paper also uses a composite set of existing popular generic evaluation methods which can be used as part of these strategies. The methods used are …
A Corba-Base Integration Of Distributed Electronic Healthcare Records Using The Synapses Approach, Jane Grimson, William Grimson, Damon Berry, Gaye Stephens, Eoghan Felton, Dipak Kalra, Pieter Toussaint, Onno Weir

The ability to exchange in a meaningful, secure, and simple fashion relevant healthcare data about patients is seen as vital in the context of efficient and cost-effective shared or team-based care. The electronic healthcare record (EHCR) lies at the heart of this information exchange, and it follows that there is an urgent need to address the ability to share EHCR's or parts of records between carers and across distributed health information systems. This paper presents the Synapses approach to sharing based on a standardized shared record, the Federated Healthcare Record, which is implemented in an open and flexible manner using …

Strategic managers and IS professionals who are responsible for specifying, acquiring and producing quality software products are not supported by the endless flow of new international standards, legislation and user requirements. In order to clarify the current situation for everybody concerned with software quality, and especially those interested in usability, there is a need for a new review and evaluation of the various strands that contribute to software quality. By way of review this paper recalls the original software quality factors which were defined twenty years ago by McCall et al. and presents a methodical analysis and synthesis of three …
Software Quality: Definitions And Strategic Issues, Ronan Fitzpatrick
Software Quality: Definitions And Strategic Issues, Ronan Fitzpatrick
Reports
This paper contains two sections relating to software quality issues. First, the various definitions of software quality are examined and an alternative suggested. It continues with a review of the quality model as defined by McCall, Richards and Walters in 1977 and mentions the later model of Boëhm published in 1978. Each of McCall's quality factors is reviewed and the extent to which they still apply in the late 1990s is commented on. The factors include, integrity, reliability, usability, accuracy, efficiency, maintainability, testability, flexibility,interface facility (interoperability), re-usability and transferability (portability). They are subdivided into external and internal quality factors. Interrelationships …

An Expert System-Based Approach To Hospitality Company Diagnosis, Andrew Balfe, Peter O'Connor, Ciaran Mcdonnell
Conference papers
This paper describes the development of a prototype Expert System-based Analysis and Diagnostic (ESAD) package for the Hotel and Catering Industry. This computerised tool aids the hospitality manager in methodically scrutinising the hotel unit and environment, combining key information with systematic reasoning. The system searches through its extensive knowledge base, investigating complicated relationships. The number of possibilities considered is increased which will broaden the depth and breadth of the analysis and therefore should improve the quality of the managers decision making.
