We believe that a deeper understanding of the uses of contexts, in terms of its impact on
knowledge representation structures, as reflected by a corpus of examples, is vital to the …

We have reanalyzed the Voyager radio occultation data for Titan, examining two alternative
approaches to methane condensation. In one approach, methane condensation is facilitated …

Global information systems have the potential of providing decision makers with timely
spatial information about earth systems. This information will come from diverse sources …

Spatial models of ecological and hydrological processes are widely used tools for studying
natural systems over large areas. However, these models lack specific mechanisms for …

We introduce a new modeling approach called meta-modeling and illustrate its practical
applicability to the construction of physically-based ecosystem process models. As a critical …

Most Artificial Intelligence programs lack generality because they reason with a single
domain theory that is tailored for a specific task and embodies a host of implicit assumptions …

We develop a model-based approach to reasoning, in which the knowledge base is
represented as a set of models (satisfying assignments) rather then a logical formula, and …

Playful and gameful design could improve the quality of scientific software. However,
literature about gamification methods for that particular type of software is presently scarce …

Scientists and engineers face recurring problems of constructing, testing and modifying
numerical simulation programs. The process of coding and revising such simulators is …

The process of creating scientific software is expensive. It requires a costly combination of
technical scientific and software development expertise. Much of the process of creating …
