Customer expectations of gateway services as well as their information needs are dynamic. The Australasian Virtual Engineering Library (AVEL) has consequently taken an iterative approach to interface design, usability testing and customer needs analysis. User-centred design has ensured that AVEL remains relevant to the way its target audience seeks information to solve “real world” problems. Th...

Software prototyping is considered to be one of the most important tools that are used by software engineers nowadays to be able to understand the customer’s requirements, and develop software products that are efficient, reliable, and acceptable economically. Software engineers can choose any of the available prototyping approaches to be used, based on the software that they intend to develop ...

Knowledge of the responsibilities of engineers is the foundation for answering ethical questions about the work of engineers. This paper defines the responsibilities of engineers by considering what constitutes the nature of engineering as a particular form of activity. Specifically, this paper focuses on the ethical responsibilities of engineers qua engineers. Such responsibilities refer to th...

This paper is on the automation of knowledge-intensive tasks in engineering domains; here, the term “task” relates to analysis and synthesis tasks, such as diagnosis and design problems. In the field of Artificial Intelligence there is a long tradition in automated problem solving of knowledge-intensive tasks, and, especially in the early stages, the search paradigm dictated many approaches. La...

On 5 and 6 May the BMJ held a conference in Oxford to discuss the next 30 years. By invitation, five of the participants prepared working papers, which were circulated beforehand; we print these below, together with an edited version of the discussion. A sixth paper, also prepared for the conference by Professor Rudolf Klein, appears on p 73. The sessions were chaired by Professor Klein and mem...

Beyond Technology—Renaissance Engineers T O compete in newly emerging international markets, industry must be committed to technological change and innovation. Today's power brokers must make an attempt to keep pace with rapid changes in technology, which is somewhat like trying to change the oil in a car while it is traveling 70 mi/h down the highway. In this super-charged atmosphere, engineer...

The golden age of road demand modeling began in the 1950s and flourished 1960s face major construction needs. These macro models, as well econometrics data to be processed, were provided mainly by engineers. A division tasks can observed between engineers charge estimating flows within network transport economists managing these once they are on network. Yet inability explain their decision-mak...
