Study of wireless experiment platform in 60 GHz by Yuannian QIN, Chuan ZOU, Zhaoyu TENG

“…A scheme of 60 GHz wireless experimental platform was presented.The platform was made up of NI USRP（transceiver module），NetFPGA（data processing module）and PC（control module）.NI USRP was connected with NetFPGA by Gigabit Nthernet interfaces，while NetFPGA was connected with PC by PCI-bus.This experiment platform works on Linux with the help of LabVIEW.The transceiver and data process module are reprogrammable.Many operations such as data stream capturing，classification and speed limit could be done with Linux and PCI.The platform has good performances in open-ended and expansibility.That would be convenient for farther research in channel modeling，timeslot allocation and multiple access algorithms.…”

Research on the Scheme of Churn Suppression for Wireless Mesh Network by Guangxue Yue, Dan Luo, Jiansheng Liu, Mingming Li

“…Through analysis of behavioral characteristics of churn nodes in wireless mesh network, a schema was proposed to improve the speed limit caused by congestion. The basic idea of the approach is to heuristically select the service nodes with lowest churn rate when it accesses the streaming media, where the churn rate is predicted through a utility function. …”

Investigation into Interactions between Accident Consequences and Traffic Signs: A Bayesian Bivariate Tobit Quantile Regression Approach by Xuecai Xu, Željko Šarić

“…Results revealed that (1) low visibility and the number of invalid traffic signs per km increased the accident rate of material damage, death, or injury; (2) average speed limit exhibited a close relation with accident rate; and (3) the number of mandatory signs was more likely to reduce the accident rate of material damage, while the number of warning signs was significant for accident rate of death or injury.…”
