Proposal for a Simplified CFD Procedure for Obtaining Patterns of the Age of Air in Outdoor Spaces for the Natural Ventilation of Buildings

Energies, 2017
Built urban environments modify the air quality of the natural ventilation processes in buildings. The experimental assessment of outdoor air change (OACH) processes is complex due to the air volumes involved.

Judging the Spatial Relevance of Documents for GIR [PDF]

, 2006
Geographic Information Retrieval (GIR) is concerned with the retrieval of documents based on both thematic and geographic content. An important issue in GIR, as for all IR, is relevance. In this paper we argue that spatial relevance should be considered independently from thematic relevance, and propose an initial scheme.

Granularity as a qualitative concept for GIR [PDF]

Proceedings of the 9th Workshop on Geographic Information Retrieval, 2015
We examine the notion of granularity for qualitative thinking about geospatial data and location references. Granularity can be understood as an abstraction of level of detail or spatial resolution. Pure coordinates, which may exhibit strong overprecision for some entities, can be combined with not only hierarchical gazetteer information, but also with
