Given a query string and a collection of strings, the top-k string similarity search is to find the k most similar strings in the collection to the query string based on edit distance. Most existing works have focused on a filter-and-verify framework to prune non-candidates with some lower bounds of edit distance. The best current implementations require more than 10 seconds answering a top-40 query...
In this paper, we mainly study finite-time input-to-state-stability (finite-time ISS) for the multi-agent systems with communication noise under switching interaction topologies, using the method of ISS, finite-time finite-time ISS-Lyapunov function.
The string similarity join is a basic operation of many applications that need to find all string pairs from a collection given a similarity function and a user-specified threshold. Recently, there has been considerable interest in designing new algorithms with the assistant of an inverted index to support efficient string similarity joins. These algorithms typically adopt a two-step filter-and-refine...
Study effect of different concentrations (1◇10,1◇50,1◇100,1◇200)water extract from Alnus nepalensis D.Don on the seed germination and allelopathic physiology and biochemistry characteristics effects of Pinus yunnanensis Faranch. Pre-test tube method was used with qualitative analysis of organic components of water extract from A.nepalensis D.Don. Results showed that water extract of A. nepalensis...
Local area network (LAN) security evaluation has not only become more important but also affected the LAN or internet advancement and development. Above all, the LAN security characteristics of are analyzed. On the basis, the quality evaluation system framework of LAN security indicator is established. Fuzzy evaluation index system is established to consider various influential factors. As to indexes...
This work studies the performance of a data-driven reduced rank scheme for rapid timing acquisition in multiple access communications. Our results show that when only a limited amount of preamble bits are available, instead of the true second-order statistics (SOS), the reduced rank scheme provides reliable timing information. Exploiting the structure of the multiple access interference, the data...
