Towards Modeling Dynamic Behavior with Integrated Qualitative Spatial Relations
نویسندگان
چکیده
Situation awareness and geographic information systems in dynamic spatial systems such as road traffic management (RTM) aim to detect and predict critical situations on the basis of relations between entities. Such relations are described by qualitative calculi, each of them focusing on a certain aspect (e. g., topology). Since these calculi are defined isolated from each other, dependencies between then are not explicitly modeled. We argue, that a taxonomy—containing a plethora of special cases of inter-calculi dependencies—can only be defined in a consistent manner, if evolution of entities and the relations of calculi are grounded in a unified model. In this paper, we define such a unified model, which is used to derive a taxonomy of inter-calculi dependency constraints contained in an ontology utilizing various spatial calculi. The applicability of this approach is demonstrated with a case study in RTM, and concluded with lessons learned from a prototypical implementation.

متن کاملOn the effect of grain size on rock behavior under cyclic loading by distinct element method
It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
متن کاملSpatial Reasoning with Integrated Qualitative-Metric Fuzzy Constraint Networks
Qualitative Spatial Reasoning can be greatly improved if metric information can be represented and reasoning can be performed on it; moreover, modelling vagueness and uncertainty in both qualitative and metric relations allows reasoning in a more flexible way about data coming from real world. In this paper Rectangle Algebra is integrated with a bi-dimensional Point Algebra by defining a set of...
