Abstract We propose a simple model for distributed query processing based on the concept of array . Such an has fields some data type whose values can be stored different machines. It offers operations to manipulate all in parallel within algebra The arrays considered are one-dimensional and just serve partitioned set. Distributed rest given set types called basic implemented by piece software ...

After more than twenty years busily mapping the human brain, what have we learned from neuroimaging? This review (coda) considers this question from the point of view of structure-function relationships and the two cornerstones of functional neuroimaging; functional segregation and integration. Despite remarkable advances and insights into the brain's functional architecture, the earliest and s...

Distributed or decentralized estimation of covariance, and distributed principal component analysis have been introduced studied in the signal processing community recent years, applications array indicated some detail. Inspired by these, this paper provides a detailed development several algorithms for processing. New are proposed DOA methods like root-MUSIC, total least squares-ESPRIT, FOCUSS...
