Enabling the user of a graph drawing system to preserve the mental map between two different layouts of a graph is a major problem. Whenever a layout in a graph drawing system is modified, the mental map of the user must be preserved. One way in which the user can be helped in understanding a change of layout is through animation of the change. In this paper, we present clustering-based strateg...

Enaminones are chemical compounds consisting of an amino group (−N=) linked through a C=C to a C=O group. In this research, four various enaminone structures were theoretically optimized. These enaminone structures have been studied for substituent effect on hydrogen bond, method and basic set effects on the geometrical parameters, vibrational frequencies and etc. Drawing molecular structures a...

In Situational Method Engineering, the concepts of both fragment and chunk have been proposed as the atomic element. These are examined here in terms of their conceptual integrity and in terms of how they may be used in method construction, drawing parallels to show that the similarities are more than the differences. The new ISO/IEC 24744 standard metamodel is used as a conceptual framework to...

GIS are an important tool to deal with spatial data as well the Bayesian method is a powerful technique to statistical data analysis. This paper describes the state of the art on GIS and Bayesian Inferential Models softwares integration and shows alternatives to improve it. Resumo. O objetivo deste artigo é descrever o estado da arte da integração entre SIG e Modelos Inferenciais Bayesianos, co...

Conceptual maps have been used in many areas as a means of capturing and representing knowledge. Several authors have explored the use of visual tools to enhance the learning process. Thinking maps as well as frame games use visual patterns of relationships (learners thinking processes) to structure knowledge. Based on their graphical structure it is possible to recognize the thinking process(e...

Previous conceptual structure editors have focussed on providing specialised drawing tools. Although the drawing operations in these tools produce the appropriate notation, they can not directly support the language of conceptual structures. Authors are required to consider both the logistics of creating neat drawings, as well as their meaning. Logicians investigating new proof techniques are h...
