Abstract: The present invention provides an electronic documents management system and method for classifying, publishing, searching and locating electronic documents. Electronic documents are classified and published via an ontological description consisting of at least one vector, each vector comprising at least one feature-value pair. Each vector's slot corresponds to a feature and the vector's range of each slot corresponds to the set of all possible values of each feature. In order to classify an electronic document, two hashing functions are applied. A first hashing function maps each feature to a slot number, corresponding to a coordinate in the appropriate vector. A second hashing function maps the value of each pair to a numeric value of a slot, corresponding to the range of each coordinate. The result of the two hashing functions is an ordered vector that can be mapped to a node in hypercube.

Abstract: The present invention relates to a hierarchical system and method for task assignment (TA), coordination and communication of multiple Unmanned Aerial Vehicles (DAV's) engaging multiple attack targets and conceives an ad-hoc routing algorithm for synchronization of target lists utilizing a distributed computing topology. Assuming limited communication bandwidth and range, coordination of UAV motion is achieved by implementing a simple behavioral flocking algorithm utilizing a tree topology for target list routing. The TA algorithm is based on a graph-theoretic approach, in which a node locates all the detectable targets, identifies them and computes its distance to each target. The node then produces an attack plan that minimizes the sum of distances of the UAV's in the subtree of a given node to the targets.
