log-log paper
5.To overcome the difficulties that the centralized information retrieval system has in coverage, freshness, access control, specialty, and network load, a scalable distributed information retrieval system was designed and implemented. The statistical information and search engine log was used to describe resource, the log-based CORI algorithm proposed in this paper is used to select resource.
7.This paper develops a sonar simulation system that is an important component in integrated simulation system. According to the new Doppler Velocity Log fixed on underwater vehicle and correlative documents about acoustic modelling and signal processing, this paper carefully analyses the error source of the Doppler Velocity Log, then builds a model for the Doppler Velocity Log and develops a sonar simulation system.
9.On the basis of Rytov?s variance and using Andrews? model, log-intensity variance for partial coherent beam transmitting through strong turbulence is deduced in this paper.
10.This model is constructed by one Omega -1 +Omega network and one simplified Omega -1 ×Omega network with series-wound connection pattern, and the total switches are 2N log N-N/2.As the melioration of FuO network, this paper presents a rotative Omega -1 ×Omega network ,whose switches are N log N-N/2,more less than FuO network,with the given routing algorithm, the network can realize non-blocking multiple multicast.
