Extension Language Automation of Embedded System Debugging

Embedded systems contain several layers of target processing abstraction. These layers include electronic circuit, binary machine code, mnemonic assembly code, and high-level procedural and object-oriented abstractions. Physical and temporal constraints and artifacts within physically embedded systems make it impossible for software engineers to operate at a single layer of processor abstraction. The Luxdbg embedded system debugger exposes these layers to debugger users, and it adds an additional layer, the extension language layer, that allows users to extend both the debugger and its target processor capabilities. Tcl is Luxdbg's extension language. Luxdbg users can apply Tcl to automate interactive debugging steps, to redirect and to interconnect target processor input-output facilities, to schedule multiple processor execution, to log and to react to target processing exceptions, to automate target system testing, and to prototype new debugging features. Inclusion of an extension language like Tcl in a debugger promises additional advantages for distributed debugging, where debuggers can pass extension language expressions across computer networks.

Promotion and prevention orientations in the choice to attend lectures or watch them online

When presented with the option to use a new instructional technology, students often face an approach–avoidance conflict. This study explored promotion and prevention orientations, concepts linked to approach and avoidance in Higgins's regulatory focus theory, in the choice to attend lectures or watch them online. Openness, a core disposition in the Big Five Model of personality, and positive attitudes towards the utility of the Internet, reflect promotion orientations that are potentially related to the choice to watch lectures online. By contrast, neuroticism, another core disposition in the Big Five Model, and anxiety about the Internet as a computer technology, reflect a prevention orientation that is potentially related to the choice of attending lectures in class. The results illustrate that both promotion and prevention are at work in the choice to attend lectures or to watch them online. Neuroticism and anxiety about the Internet as a computer technology were related to the choice to attend lectures in class, whereas the perceived utility of the Internet was related to the choice to watch lectures online. Instructional mode choice was not related to examination performance, suggesting that the choice to attend lectures or watch them online has more to do with individual differences in promotion and prevention orientations than with pedagogical characteristics that impact learning.

The electrical distribution network planning problem

In this paper we are dealing with the electrical distribution network planning problem where a network configuration has to be specified in order to meet demand, to satisfy the operating constraints, and to minimize investment, operating, and power–loss costs. The iterative procedure includes several heuristic algorithms to generate a radial network, to choose a set of open feeders to meet the reliability constraint, and to solve the reconfiguration problem in order to reduce the power–loss costs. Furthermore, in order to compare the reliability of potential solutions, a predictive reliability assessment measure is established.

A Manifesto for Agent Technology: Towards Next Generation Computing

The European Commission's eEurope initiative aims to bring every citizen, home, school, business and administration online to create a digitally literate Europe. The value lies not in the objective itself, but in its ability to facilitate the advance of Europe into new ways of living and working. Just as in the first literacy revolution, our lives will change in ways never imagined. The vision of eEurope is underpinned by a technological infrastructure that is now taken for granted. Yet it provides us with the ability to pioneer radical new ways of doing business, of undertaking science, and, of managing our everyday activities. Key to this step change is the development of appropriate mechanisms to automate and improve existing tasks, to anticipate desired actions on our behalf (as human users) and to undertake them, while at the same time enabling us to stay involved and retain as much control as required. For many, these mechanisms are now being realised by agent technologies, which are already providing dramatic and sustained benefits in several business and industry domains, including B2B exchanges, supply chain management, car manufacturing, and so on. While there are many real successes of agent technologies to report, there is still much to be done in research and development for the full benefits to be achieved. This is especially true in the context of environments of pervasive computing devices that are envisaged in coming years. This paper describes the current state-of-the-art of agent technologies and identifies trends and challenges that will need to be addressed over the next 10 years to progress the field and realise the benefits. It offers a roadmap that is the result of discussions among participants from over 150 organisations including universities, research institutions, large multinational corporations and smaller IT start-up companies. The roadmap identifies successes and challenges, and points to future possibilities and demands; agent technologies are fundamental to the realisation of next generation computing.     

The reality of medical work: The case for a new perspective on telemedicine

This paper considers the nature of medical work and how new telemedicine technologies can be developed to support that work. Telemedicine developers attempt to increase communication and collaboration between medical practitioners and between patients and medics, with the goal being to make medical care and information more easily accessible. However, the focus of telemedicine systems appears to have so far been technology centred, and the work they are trying to support is often ignored. We argue that to develop appropriate telemedicine technologies, it is important to understand the nature of medical work, and to examine the manner in which medical practiceactually occurs. Only then will we be in a position to design appropriate telemedicine technologies to support these activities. Unless designers have an insight into the work itself, new technologies will continue to fail to support what telemedicine effectively aims to promote — collaboration and access to distributed knowledge.
