With the increasing interest in metamodeling techniques for Domain Specific Modeling Languages (DSML) definition, there is a strong need to improve the language modeling process. One of the problems to solve is language evolution. Possible solutions include maximizing the reuse of metamodel patterns, composing them to form new, more expressive DSMLs. In this paper we improve the process of rapi...

This work describes a way of interactive manipulation of structured objects by interaction rules. Symbols are used as graphical representation of object states. State changes lead to different visual symbol instances. The manipulation of symbols using interactive devices lead to an automatic state change of the corresponding structured object without any intervention of the application. Therefo...

The semantics of programming languages lack a formal, standardized specification language. We focus on control flow semantics and propose a graphical specification framework for these semantics, consisting of three elements: a graphical control flow specification language, a rule-based approach for constructing flow graphs and transformations from the former to the latter. In this thesis we int...

The linear list presentation of results used by most information retrieval systems does not help the user to evaluate the results for relevance. Five alternative presentations, one tabular and four graphical, were designed and implemented. Three of the graphical presentations, bar charts, matrix charts, and scatter plots were existing techniques. The fourth, document maps, was a new visualisati...

PURPOSE The PathVisio-Validator plugin aims to simplify the task of producing biological pathway diagrams that follow graphical standardized notations, such as Molecular Interaction Maps or the Systems Biology Graphical Notation. This plugin assists in the creation of pathway diagrams by ensuring correct usage of a notation, and thereby reducing ambiguity when diagrams are shared among biologis...

An extension to curly arrow rules for the prediction of quantum interference behaviour in conjugated molecular wires widens scope this simple graphical method containing heteroatoms, cross-conjugation and/or non-alternant structures.

Today's graphical user interfaces simulate a perfect world. Windows have always the same look and buttons have identical shapes and colors and are aligned to regular grids. The only distinction between graphical elements is their label. The current visual design of user interfaces ignores the capabilities of modern displays for an eeective visual coding and the resulting uniformness makes it ve...
