How can we represent spatial information in maps in a cognitively adequate way? The present article outlines a cognitive conceptual approach that proposes primitive conceptual elements from which maps can be constructed. Based on work in geography that starts with abstract models of geographic phenomena, namely modelisation chorematique by R. Brunet (1980, 1987), we coin primitive conceptual el...

Residue curve maps are a powerful tool for the preliminary design of Reactive Distillation (RD). In this study, residue curve maps of the n-butyl acetate synthesis reaction were calculated based on the Langmuir–Hinshelwood–Hougen–Watson kinetic and UNIQUAC models to calculate the physical properties of the system. The results showed that the unstable node branch emerged from the n-butyl ace...

Conceptual models of information systems emerge as the result of cooperation among diierent user groups. There are however few research eeorts focused on providing collaboration support for this activity. This thesis aims at suggesting methods and tools originating from CSCW research eld for supporting collaborative conceptual modeling. A framework for studying collaboration support for user pa...

extended abstractintroductiona map is a drawing ground features on one side of the paper. the cartographic maps are representations of the earth upon a flat surface in the smaller scale than it’s true. large scale maps cover relatively small regions in great detail and small scale maps cover large regions such as nations, continents and the whole globe. logical connection between the features a...

We describe tools that use conceptual maps to manage the atomic content of a e-learning platform and to assess the conceptual learning of the students.

Advanced computer-based concept-mapping tools are suggested to have the potential to foster spatial learning strategies and processes of individual knowledge management like the acquisition, organization, representation, (self-) evaluation, communication, localization and utilization of knowledge. In addition, they have the potential to represent not only conceptual knowledge, but also content ...

Interoperability and integration of digital concept mapping tools has not been widely prioritized and supported by software developers. Digital alternatives to paper-based concept mapping (from simple digital whiteboard to dedicated concept mapping software) are increasingly popular among educators, but computer-based concept maps are still difficult to analyze, assess, expand or export to othe...

The objective of the presented research is to construct a model of a patient’s health that is based on the idea of cognitive map, a graphical knowledge-representation tool. The application of the proposed model for medical diagnosis is the practical goal of the research. Initially, we provide a brief review of the related works on medical decision support systems and cognitive maps. Afterwards,...

The traditional spatial data models model space in terms of points, lines, and regions. These models employ a disjoint dimension model in which a spatial object can only consist of a zero, one, or twodimensional point set. However, such models cannot adequately represent spatial reality. For example, consider a river network that contains both rivers and lakes. Intuitively, this river network i...
