A distributed agent architecture for real-time knowledge-based systems: Real-time expert systems project, phase 1

We propose a distributed agent architecture (DAA) that can support a variety of paradigms based on both traditional real-time computing and artificial intelligence. DAA consists of distributed agents that are classified into two categories: reactive and cognitive. Reactive agents can be implemented directly in Ada to meet hard real-time requirements and be deployed on on-board embedded processors. A traditional real-time computing methodology under consideration is the rate monotonic theory that can guarantee schedulability based on analytical methods. AI techniques under consideration for reactive agents are approximate or anytime reasoning that can be implemented using Bayesian belief networks as in Guardian. Cognitive agents are traditional expert systems that can be implemented in ART-Ada to meet soft real-time requirements. During the initial design of cognitive agents, it is critical to consider the migration path that would allow initial deployment on ground-based workstations with eventual deployment on on-board processors. ART-Ada technology enables this migration while Lisp-based technologies make it difficult if not impossible. In addition to reactive and cognitive agents, a meta-level agent would be needed to coordinate multiple agents and to provide meta-level control

Coordination approaches and systems - part I : a strategic perspective

This is the first part of a two-part paper presenting a fundamental review and summary of research of design coordination and cooperation technologies. The theme of this review is aimed at the research conducted within the decision management aspect of design coordination. The focus is therefore on the strategies involved in making decisions and how these strategies are used to satisfy design requirements. The paper reviews research within collaborative and coordinated design, project and workflow management, and, task and organization models. The research reviewed has attempted to identify fundamental coordination mechanisms from different domains, however it is concluded that domain independent mechanisms need to be augmented with domain specific mechanisms to facilitate coordination. Part II is a review of design coordination from an operational perspective

Indeed, the individual work of the members of the group as well as the group work as a whole need the calendar to guide their activity and to meet the deadlines, milestones, deliverables of a project, etc. Additionally the members of the group should be able to work both offline and online, which arises when members of the group use smartphones and can eventually run out of Internet connection from time to time, or simply want to develop some activities locally. In the former case, they should have access to the calendar locally, while in the later case they should access the calendar online, shared by all members of the group. In both cases they should be able to see eventually the same information, namely the local calendars of the members should be synchronized with the group calendar. For the case of smartphones under Android system, one solution could be using the Google calendar, however, that is not easily tailorable to collaborative group work. In this paper we present an analysis, design and implementation of group work calendar that meets several requirements such as 1) sharing among all of members of the group, 2) synchronization among local calendars of members and global group calendar, 3) conflict resolution through a voting system, 4) awareness of changes in the entries (tasks, members, events, etc.) of the calendar and 5) all these requirements under proper privacy, confidentiality and security mechanisms. Moreover, we extend the sharing of calendars among different groups, a situation which often arises in enterprises when different groups need to be aware of other projects' development, or, when some members participate in more than one project at the same time.Peer ReviewedPostprint (author's final draft

Online interactivity: best practice based on two case studies

The purpose of this paper is to identify and explore best practice in the effective support of online interactivity. Five key issues related to best practice are delineated, based on the experience derived from two case studies. The first case study involved online, collaborative work carried out by twenty-six conversion M.Sc. students following a module on‘Interactive Multimedia Systems'. The online group work was structured around the production of essay-style critiques and the development of prototype multimedia resources. The discussions were structured using the bulletin board facility in WebCT. The second study involved sixty-four second-year undergraduate students following a module on‘Communication via Multimedia’. These students were involved in assessed online discussion groups that aimed to foster a community in enquiry and provide an opportunity for vicarious learning. The assessed discussion groups were based on Netscape Collabra. A comparison of the experience of these two case studies led to the identification of a set of five key issues relating to best practice in the effective support of online interactivity. The first four issues concern the design and implementation of the online learning experiences. The fifth issue involves reflection and improvement on the interventions mad

Ground Rules in Team Projects: Findings from a Prototype System to Support Students

Student team project work in higher education is one of the best ways to develop team working skills at the same time as learning about the subject matter. As today’s students require the freedom to learn at times and places that better match their lifestyles, there is a need for any support for team project work to be also available online. Team working requires that the task roles as well as the maintenance roles are taken into consideration, in that social interactions are just as important as carrying out the tasks of the project. The literature indicates that groupware, whilst effective in supporting the task roles, provides limited support for the maintenance roles of team working in the work place. As groupware was not specifically designed for student team working, it provides limited support for maintenance roles in student team projects. Virtual learning environments similarly provide support for completing the task roles. Many researchers have found that students experience difficulties with their team project work that reduce the perceived benefits of working in a team. It is proposed that helping students to agree on ground rules at the start of a project will improve team cohesion. This paper describes the implementation and evaluation of a prototype system to help students to agree on ground rules as they start their team projects. The system was tested with teams of students carrying out information systems team projects, using an interpretive case study research approach. In this case the teams had the additional problem of being composed of students from across three years of their undergraduate degree programmes, so they did not always have prior knowledge of each other’s preferences. We were trying to establish how useful this software tool would be to these student teams, in starting their project work. The findings showed that some of the student teams did find the ground rules function useful, but the team leaders were the ones who most appreciated its potential. The students may use the outputs in very different ways, but even just looking at the ground rules appeared to get team members thinking about their expectations for team working. Student teams do not often start by thinking about norms, but this study shows a positive benefit of encouraging teams to agree on ground rules at the start of their projects

The Future of American Farming: Broadband Solutions for the Farm Office, Field, and Community

Innovation has long been a hallmark of American agriculture. American farmers have continuously adapted their operations to meet new demand and stay competitive in an increasingly globalized economy.Today, broadband is a necessary tool to innovate farming practices, allowing for more targeted and efficient resource use. Farmers need connectivity in the farmhouse and farm office, in the field, and in the community. But evidence shows that a majority of American farmers lack the connectivity required.How can we deliver the broadband that farmers need?As the Benton Institute for Broadband & Society interviewed farmers, rural service providers, equipment manufacturers, and other agricultural leaders and experts, broad consensus arose around several key outcomes for rural broadband, such as the need for robust upload speeds, accurate network deployment data, and scalable technologies. Farmers know what they need for sustainable, data-driven agriculture that can keep pace with the world's rising food demand. Now it's time to hear them and deploy the broadband networks and adoption strategies they require to continue to innovate and feed the world

Towards a New Dimension in Clinical Information Processing (Keynote)

Process-oriented information systems can be very valuable for the clinical personnel since they may actively support the processes in a hospital. By offering tasks right in time and when all information is available to perform them, and by obeying deadlines and other time constraints, it reduces the administrative overhead. Today’s WF technology is still too limited in order to be broadly applicable in this scenario. However, research in WF technology is making quick progress. In the foreseeable future one can expect very powerful WfMS to appear at the market place, offering a powerful platform for implementing process-oriented information systems, also in the clinical domain. This paper sketches the ADEPT WfMS prototype, which is among the functionally most powerful WfMS and proves that one can really build systems of this kind which offer all this functionality within one system
