Prefabrication and suspended splicing of continuous concrete box girders by segment short-line matching method;

In this paper,a mechanism of query-biased summarization is presented based on passage matching and density distribution.

The subject about the sequence acquisition under large frequency offset and low signal to noise ratio in DS sys- tems was researched,and evaluation of the influence on system detection-rates and ability against frequency offset when sectional matching mode implemented was presented in this paper.
