Architects form an integral link in the design of e.cient buildings. Energy-e.cient design strategies therefore, require architects and engineers to work closely together in optimising the building shell. However, this is not always practical. Architects must therefore, be able to perform a preliminary thermal analysis if energy e.cient design strategies are to succeed. Existing tools do not ca...

Digalo is a graphic-based software tool for supporting collaborative argumentation and structured discussion. It has been developed in the framework of the DUNES project (IST-2001-34153, http://www.dunes.gr ). Using Digalo consists of synchronously co-creating maps built of written notes inside different cards (represented by diverse geometrical shapes), as well as using different arrows to rep...

Parametric representation of fuzzy numbers (PFN) with derived methods for performing fuzzy arithmetic proves to have better accuracy and similar computational speed to using triangular fuzzy numbers (TFN). These fuzzy numbers (PFN) can be considered a special case of triangular fuzzy numbers (TFN) as they have three additional parameters and their methods for arithmetic operations are further s...

Most efforts to create computer-supported collaborative learning environments have been focused on students. However, without providing appropriate integration of collaborative activities into curricula, these efforts will have little widespread impact on educational practices. To improve education through technology, learning environments for students must be integrated with curriculum develop...

This paper shows a way to treat the different and sometimes contradictory opinions from a group of experts to reach a global agreement about potential future scenarios in strategic planning. To achieve this objective we have worked on the development of a methodology and a software tool that permits the creation of possible future scenarios from individual opinions. The methodology and the soft...

This paper proposes a model for compatibility analysis to support Web Services substitution within cooperative processes. In order to properly take into account both the syntactic and the semantic issues, this model is based on the use of service descriptors and on a software tool environment to perform the semantic analysis of descriptors.

Even though there has been a considerable amount of progress on software development tools, techniques, methodologies and SDLCs, still %68 of software development projects are unsuccessful. In this study, Flexible and Adaptive Life Cycle (FALC) Framework is introduced to manage the utilization of different SDLCs in the projects in order to increase success rates. The FALC Framework provides opp...

DefibViz is a software tool for defibrillation simulation and the visualization of the resulting voltage gradient induced throughout the human heart and torso. This paper presents an extension to DefibViz that provides functionality for the interactive placement of multiple sets of transthoracic electrodes of varying shape, size, and applied voltage. Such a tool may provide biomedical engineers...

Widely used statistical graphs (such as line graphs and bar graphs) are usually accompanied by graphical entities other than the graph proper. Those graphical cues, such as point marks and arrows serve for communicative purposes by bringing certain aspects to the foreground over the others. The present study discusses the results of an experimental investigation, in which the participants produ...

What if {a tourist, a train addict, Dr. Sheldon Cooper, somebody who likes to waste time} wants to visit all metro lines or carriages in a given network in a minimum number of steps? We study this problem with an application to the Parisian metro network and propose optimal solutions thanks to mathematical programming tools. Quite surprisingly, it appears that you can visit all 16 Parisian metr...
