Division

Bad Arguments, 2018
We describe the capabilities and limitations of two daylighting computer programs, the algori thms used 'in each, resul ts of val ida tion studies, and sample resul ts using each of these programs. We also describe features now under development for both

Joint Spatial Division and Multiplexing—The Large-Scale Array Regime

IEEE Transactions on Information Theory, 2012
We propose joint spatial division and multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of the correlation of the channel vectors in order to allow for a large number of antennas at the base station while requiring ...

The division “Synergistes”

Anaerobe, 2007
The "Synergistes" group of organisms are a phylogenetic cluster of Gram-negative anaerobes related to Synergistes jonesii, sufficiently distinct from all other phyla to be considered a distinct phylum or Division. They are widely distributed in nature although normally only a minor constituent of the bacterial community in each habitat.
