The range dependence for clutter spectrum is theoretically analyzed and simulated in bistatic airborne sidelooking radar with the vertical and horizontal baselines.

The existence of long-distance dependencies in language makes parsing difficult, that is to say, words and phrases that are related to one another are not necessarily adjacent in a sentence.

Research and simulation of dynamic distance vector QoS routing algorithm;

Second, the classifier creates rule vector according to each groups of keywords and weights, which includes weight vector and distance vector.

With simple implementation and lower requirewment, the DV (distance vector)-based localization algorithms meet the requirement of WSN.

After analyzing several methods of query expansion based on mutual information, this paper introduces the vector distance between terms in documents space to the improvement of mutual information and brings forward a query expansion method based on vector distance in documents space.

Since word order similarity is the main factor to the ranking results,an algorithm based on vector distance is devised to compute word order similarity in this paper.
