Spatial Representation and Reasoning using the N-Dimensional Projective Approach

The n-dimensional projective approach as a tool for spatial reasoning

In this paper, we describe the n-dimensional projective approach as a hierarchical and modular architecture with a processing mechanism that underlies both spatial backtracking and multiple physical properties of entities. Also, it is shown in Euclidean space how cognitive activities of an agent are improved in terms of flexibility (e.g. alternative solutions), reliability (e.g. error recovery)...

Tesseral spatio-temporal reasoning for multi-dimensional data

1 SUMMARY A quantitative spatio-temporal reasoning mechanism founded on a tesseral representation of space is described. The principal advantages of this mechanism are that it is generally applicable to any N-dimensional space while at the same time providing for eeective manipulation and comparison of objects located within such spaces. These advantages are a direct consequence of the derived ...

A novel model of clinical reasoning: Cognitive zipper model

Introduction: Clinical reasoning is a vital aspect of physiciancompetence. It has been the subject of academic research fordecades, and various models of clinical reasoning have beenproposed. The aim of the present study was to develop a theoreticalmodel of clinical reasoning.Methods: To conduct our study, we applied the process of theorysynthesis in accordan...

A Projective approach to handle 3D spatial data

1. Introduction The choice of relevant data models and data structures is still an important issue in 3D GIS. In the 3D urban GIS context, boundary representation models are usually adopted with different levels of " topology " integration In this work, a new approach based on projective properties of spatial objects has been adopted. The theoretical framework behind this is the Dimensional Mod...
