Managing long-term, research-oriented software projects requires more flexibility and open-endedness than most production-oriented software processes provide. We have been exploring the use of spatial hypertext to manage such projects. Spatial hypertext allows users to place information objects in visual spaces and use visual cues and spatial relations to represent inter-object relations. Over ...

The complexity of mechatronic systems in general and their control software in particular keeps increasing. For years already, model-based development promises to ease a lot of the challenges in the development of mechatronic machine controllers. Still, its adoption by machine builder companies often remains limited to the algorithmic part of the controller, typically using tools such as Mathwo...

This paper presents the design of eLeTK, which is a software system that may be used for enhancing on-line educational environments. The main concept introduced in this paper is represented by educational data/knowledge flow. The data flow is transformed into a knowledge flow provided that all input data represents activity produced by an on-line educational environment. On the other hand, the ...

As one kind of high quantity standardized commodities, the fruit juice product is an essential part to our daily life and overall economy. Therefore, it is necessary and important to design an efficient juicing and filling production line. According to deficiencies of traditional design methods, we propose a new design method by introducing virtual design technologies to develop a hybrid simula...

Many databases in life sciences have been provided in Resource Description Framework (RDF) with their SPARQL endpoints. To support a user in constructing SPARQL queries, we developed a service called SPARQL Builder. Although SPARQL Builder makes a user write a query for obtaining data from LOD, empty results or incorrect data might be retrieved by the query if the SPARQL endpoint for the query ...

Environmental problems caused by fossil fuel consumption, on the one hand, and the upcoming prospect of ending these fuels on the other, attracted much attention towards sustainable architecture. Traditional buildings can be seen as a sample of sustainability; as they have used strategies to cope with the environment, which have been developed over the years, providing users’ comfort cond...

Software architectures are the conceptual tool to share information about key aspects of a software system and to enable reasoning about the principal, most fundamental, and often most difficult-to-change design decisions of the system. Studies of failed software systems give evidence that architecture drift, erosion or degradation is a prevalent problem in industrial practice. But a recent sys...
