The combination of spatial access methods and computational geometry in geographic database systems [PDF]

open access: yes, 1991
Geographic database systems, known as geographic information systems (GISs) particularly among non-computer scientists, are one of the most important applications of the very active research area named spatial database systems. Consequently following the

Spatial grouping resolves ambiguity to drive temporal recalibration. [PDF]

open access: yes, 2011
Cross-modal temporal recalibration describes a shift in the point of subjective simultaneity (PSS) between 2 events following repeated exposure to asynchronous cross-modal inputs-the adaptors. Previous research suggested that audiovisual recalibration is
