Extrusion is widely used to construct models in 3D cadasters. However, the basic extrusion approach only supports relatively simple conditions, and a 3D cadastral data model that supports extruded 3D models that are associated with their corresponding footprints is not available. In this paper, we present a new extrusion approach based on non-overlapping footprints (EABNOF) that supports relati...

Bibliometrics has the ambitious goal of measuring science. To this end, it exploits the way science is disseminated trough scientific publications and the resulting citation network of scientific papers. We survey the main historical contributions to the field, the most interesting bibliometric indicators, and the most popular bibliometric data sources. Moreover, we discuss distributions common...

biocapacity The potential productivity of the biologically productive space within a specified country, region, or territory. biologically productive space Areas of land and water capable of supporting photosynthesis at sufficient rates to provide economically useful concentrations of biomass. Marginal and unproductive regions, such as deserts, tundra, and the deep oceans, are excluded. The glo...

A new reactive strategy for multi-path routing in mobile ad-hoc networks is presented. Given a pair of communicating stations, we use the complete set of minimal-length paths – a so-called corridor – between the two. The potentially high number of paths within a corridor is efficiently installed by virtue of a new destination-discovery mechanism that is exclusively based on broadcast transmissi...
