Improvement and Experimental Study of Loading Mode of Vacuum Preloading Method by WEI Yanbing, LI Zhenxin, LI Yao

“…For the phenomenon of “soil column” occurred in the reinforcement of mud by vacuum preloading method,in order to improve the reinforcement effect of vacuum preloading this paper summarizes and analyzes the formation mechanism of “soil column” for coming to the conclusion that the main reason for the formation of “soil column” is the silting of drainage board,proposes the method of step vacuum loading,concludes that the strength of reinforced soil increases largely under the step vacuum loading method after analysis of the theory of soil mechanics,and verifies it through the indoor model test.The results show that the permeability coefficient of the plastic drainage board decreases slightly and the consolidation settlement value of the reinforced mud is larger under the step vacuum loading,indicating that the step vacuum loading method can reduce the silting of drainage boards,delay the occurrence of “soil column” phenomenon,and improve the overall reinforcement effect of mud.…”

CC-MRSJ:Cache Conscious Star Join Algorithm on Hadoop Platform by Guoliang Zhou, Yongli Zhu, Guilan Wang

“…A cache-conscious MapReduce star join algorithm was presented,each column of fact table was separately stored,and dimension table was divided into several column families according to dimension hierarchy.Fact table foreign key column and corresponding dimension table was co-location storage,thus reducing data movement in the join process.CC-MRSJ consists of two phases:firstly each foreign key column and the corresponding dimension table were joined; then the intermediate results were joined and random accessed measure columns,and so got the final result.CC-MRSJ read only the data needed,and cache utilization is high,so it has good cache conscious feature; it also takes advantage of late materialization,avoiding unnecessary data access and movement.CC-MRSJ has higher performance comparing to hive system based on SSB datasets.…”
