A storage and access architecture for efficient query processing in spatial database systems [PDF]

, 1993
Due to the high complexity of objects and queries and also due to extremely large data volumes, geographic database systems impose stringent requirements on their storage and access architecture with respect to efficient query processing.

Image processing for optical mapping [PDF]

GigaScience, 2015
Optical Mapping is an established single-molecule, whole-genome analysis system, which has been used to gain a comprehensive understanding of genomic structure and to study structural variation of complex genomes. A critical component of Optical Mapping system is the image processing module, which extracts single molecule restriction maps from image ...

Stimulus saliency modulates pre-attentive processing speed in human visual cortex [PDF]

, 2011
The notion of a saliency-based processing architecture [1] underlying human vision is central to a number of current theories of visual selective attention [e.g., 2].

Integrating process mapping and simulation [PDF]

Proceedings of the 28th conference on Winter simulation - WSC '96, 1996
This paper presents two different yet successful approaches that have been taken for integrating process mapping technology and simulation technology. The discussion is based on two actual implementations in which two different process mapping tools were separately integrated with ProModel simulation software.
