In Concern-Orientation, software systems are built with the help of reusable artifacts called concerns, leading to reuse hierarchies, because higher-level concerns may reuse lower-level concerns. At each level in the reuse hierarchy, a concern uses goal modelling techniques to describe the impact of selected variations from the concern on system qualities such as performance, cost, and user con...

This research investigates the issues of authoring reusable BIM components that can be delivered across multiple platforms. A key constraint in the uptake of Building Information Modelling (BIM) technology is interoperability, the ability to accurately and automatically share and exchange data. This has been addressed by the creation of a system of standards; Industry Foundation Classes (Ifcs)....

A new low-cost systematic procedure to obtain high-quality data for model identification is presented. Two major steps compose this methodology: first, a simplified process model is built using a PIMS (Plant Information and Management System) database, which contains limited information about the process behavior. Second, the signal amplitudes and its directions are calculated, as well as the t...

Building information modeling (BIM) tools are increasingly present in the architecture, engineering and construction (AEC) industry. This software tool chain not only requires new knowledge on the level of technology, but moreover, a new knowledge of people related skills and re-configuration of the process. There is hope that BIM tools will increase the degree of process integration and suppor...

Conceptual data modelling is one of the critical phases in Information System (IS) development. In this paper we show the method, software tool and results on automating evaluation of Conceptual Data Model (CDM) from a semantic perspective. The approach is based on mapping ontology with CDM. An ontology that represents domain knowledge and data model are transformed into PROLOG language clauses...

Constructing a model in a hierarchical fashion is a natural approach to managing model complexity, and offers additional opportunities such as the potential to re-use model components. The SBML Level 3 Version 1 Core specification does not directly provide a mechanism for defining hierarchical models, but it does provide a mechanism for SBML packages to extend the Core specification and add add...

This paper presents the prototype of an adaptive faceted semantic browser – Factic. Factic implements our novel method of navigation in open information spaces represented by ontologies based on an enhanced faceted browser with support for dynamic facet generation and adaptation based on user characteristics. It is developed as part of a modular framework that supports personalization based on ...

Easy Java Simulations (Ejs) and Sysquake are two software tools specifically intended for implementation of virtual-labs. They allow easy definition of the virtuallab view (i.e., the model-to-user interface). However, themodel definition capabilities and the numerical solvers provided by these tools are not the state-of-the-art. On the other hand, the use of the object-oriented modelling langua...

In this paper, we present our lessons from the design and use of two educational software tools for teaching behavioral modeling to graduate students of digital art. The tools, PainterAnts and VLab, allow the experimentation and control of simulated ants that paint, or Braitenberg vehicle-like agents (Braitenberg 1984). To better address the target audience of digital art students, we have tran...

We present a software tool platform which facilitates security and performance analysis of systems which starts and ends with UML model descriptions. A UML project is presented to the platform for analysis, formal content is extracted in the form of process calculi descriptions, analysed with the analysers of the calculi, and the results of the analysis are reflected back into a modified versio...
