Voronoi-based 9-Intersection Model for Topological Spatial Relations
TL;DR: A modified version of the 9-intersection model is presented, made by replacing the complement (exterior) of an entity with its Voronoi region and the resulting new model is called Vor onoi-based 9-Intersection model (V9I).

Microscopy and image analysis of the micro-fabric and composition of saline rocks under different phaseCO2-Brine states
Ameh Peter,Ameh Peter,Xiaoqiang Jin,Xianfeng Fan,Kenneth Imo-Imo Eshiet,Yong Sheng,Dongmin Yang +6 more
TL;DR: In this article, the effect of stress corrosion on the micro-fabric, topology of the minerals and the elemental composition of saline rock was evaluated, to understand how this affect transport properties of rocks.

Spatial Query Broker in a Grid Environment
TL;DR: Government agencies, large private corporations and scientific centers are the most common producers and consumers of spatial data that are employed in decision-making systems, analysis tools and experiments.
Journal ArticleDOI
Qualitative topological relations between interval type-2 fuzzy spatial objects
TL;DR: Two methods can be used to describe the relation between two IT2 FSOs; the method proposed in this article conforms to human cognitive habits and meets the requirements of a variety of applications in geographical information systems (GIS).
Journal ArticleDOI
Analyzing topological changes for structural shape simplification
TL;DR: The approaches presented in this study can help to analyze the exact types and locations of topological changes for generalizing convexities and concavities, respectively.

Metaphors We Live By
George Lakoff,Mark Johnson +1 more
TL;DR: Lakoff and Johnson as mentioned in this paper suggest that these basic metaphors not only affect the way we communicate ideas, but actually structure our perceptions and understandings from the beginning, and they offer an intriguing and surprising guide to some of the most common metaphors and what they can tell us about the human mind.
Journal ArticleDOI
Metaphors We Live by
TL;DR: Lakoff and Johnson as discussed by the authors present a very attractive book for linguists to read, which is written in a direct and accessible style; while it introduces and uses a number of new terms, for the most part it is free of jargon.
Journal Article
Maintaining knowledge about temporal intervals
TL;DR: An interval-based temporal logic is introduced, together with a computationally effective reasoning algorithm based on constraint propagation, which is notable in offering a delicate balance between space and time.

The Theory of Parsing, Translation, and Compiling
Alfred V. Aho,Jeffrey D. Ullman +1 more
TL;DR: It is the hope that the algorithms and concepts presented in this book will survive the next generation of computers and programming languages, and that at least some of them will be applicable to fields other than compiler writing.
