We present an evaluation of the Graphical Modeling Framework (GMF) based on our experiences in developing an editor for the risk modeling language CORAS using GMF. Our main hypothesis is that GMF shortens development time and results in more reliable and maintainable systems than alternative approaches which are not based on code generation. We conclude that the hypothesis is true, but that the...

A common assumption for many process-centred support environments is that they provide the same process support at different levels of the organization. We believe that the required process support from one level to another of an organization varies. In this paper we propose a framework that divides process support into three levels: Individual, group and team level. Further, we characterize ea...

Senspectra is a computationally augmented physical modeling toolkit designed for sensing and visualization of structural strain. The system functions as a distributed sensor network consisting of nodes, embedded with computational capabilities and a full spectrum LED, which communicate to neighbor nodes to determine a network topology through a system of flexible joints. Each joint, while servi...

AnnAGNPS (Annualized AGricultural Non-point Source), a continuous simulation and distributed pollution model, is widely applied in evaluating non-point source pollution and watershed management practices. However, the complexity of required input data and modeling procedure keep it from being an efficient modeling tool. An integrated GIS interface was developed to facilitate organizing and prep...

This paper presents a novel modeling interface and method that uses two-dimensional (2D) data. In general, 2D computer graphics are most commonly used to depict 2D structures. However, many computer games often depict three-dimensional (3D) structures using 2D computer graphics. We define such an expression as an overhead view. Although an overhead view has no 3D structure, we can perceive an a...

Modeling and rendering human hair remains to be one of the most challenging computer graphics problems. This paper presents a new interactive hair modeling system featured with a user-friendly sketching interface. With the sketching interface, any user, even a first time user, can create a hair model of his/her desired style just in a few minutes simply by interactively drawing several strokes ...

For direct manipulation environment with force feedback, we propose a kind of string-based two-handed multi-fingers haptic interface device. The system can sense the positions of three fingertips and wrist on each of the user's hand. Force feedback can be perceived when the position of the finger comes into contact with the virtual object. We explain in detail about the algorithms used in the f...

Summary: Molecular Integrated Development Environment (MolIDE) is an integrated application designed to provide homology modeling tools and protocols under a uniform, user-friendly graphical interface. Its main purpose is to combine the most frequent modeling steps in a semi-automatic, interactive way, guiding the user from the target protein sequence to the final three-dimensional protein stru...
