Study on the Effect of Foundation Pit Excavation on the Deformation of Adjacent Shield Tunnel by Cirong Lu, Long Huang

“…The following conclusions are drawn: (1) the excavation of adjacent foundation pit will cause excessive displacement, settlement, and structural convergent deformation of shield tunnel, causing structural damage such as increasing of faulting, water leakage, and seeping. (2) With the decrease of the distance between the tunnel and the foundation pit, the convergent deformation of the tunnel increases continuously, and when the distance is less than 30 m, the increase of segment thickness greatly improves the convergent deformation of the structure. (3) The increase of segment thickness has no obvious effect on the resistance to longitudinal deformation. …”

Study on Directional Control Curtain Grouting Technology in Boulder-Cobble Strata by HAN Yu, YANG Jian, CAO Chunding

“…The boulder-cobble strata has the characteristic of stranger permeability along the downstream direction of the river,but the impervious curtain perpendicular to the river is difficult to form.In order to solve this problem,the grouting pipe based on embedded flower pipe technology is reformed by directional mechanical transformation.The limited energy emitted by the slurry from the pulse grouting pump is used to make the slurry penetrate along the square direction of vertical seepage,and the direction is controllable,and the grouting material and process flow are optimized.The two indexes of certain pressure and single stage suction are taken as the grouting end standard,the problems that traditional grouting method of large-size stratum such as boulder-cobble stratuml is difficult to start pressure,the cement consumption is large,and the slurry permeability path usually extends to the upstream and downstream of the river are effectively solved.The grouting test shows that the directional curtain grouting technology has good applicability to the large particle size floating gravel stratum.After the directional control grouting treatment,the water permeability is greatly reduced,which meets the anti-seepage requirements of medium and low dam foundation;it has reference significance for similar projects.…”

Vibe++ background segmentation method combining MeanShift clustering analysis and convolutional neural network by Zihao LIU, Xiaojun JIA, Sulan ZHANG, Zhiling XU, Jun ZHANG

“…To solve problems of noise points and high segmentation error for image shadow brought by traditional Vibe+ algorithm, a novel background segmentation method (Vibe++) based on the improved Vibe+ was proposed.Firstly, binarization image was acquired by using traditional Vibe+ algorithm from surveillance video.The connected regions were marked based on the region-growing domain marker method.The area threshold was obtained with difference characteristics of boundary area, the connected regions below threshold were treated as disturbing points.Secondly, five different kernel functions were introduced to improve the traditional MeanShift clustering algorithm.After improving, this algorithm was fused effectively with partitioned convolutional neural network.Finally, program of classification of trailing area, non-trailing area and trailing edge area in the resulting image was performed.Position coordinates of the trailing area were calculated and confirmed, and the trailing area was quickly deleted to obtain the final segmentation result.This segmentation accuracy was greatly improved by using the proposed method.The experimental results show that the proposed algorithm can achieve segmentation accuracy of more than 98% and has good application effect and high practical value.…”

Passive biometric electronic lock via UHF RFID by Xiang ZOU, Jinsong HAN, Yuhang QU, Jian XIAO, Xian XU

“…A biometric lock design method was proposed based on the internal features of human body, namely PBLock.It used the backscattered RF signals to collect the impedance characteristics of human fingertips through the contact between human fingers and tags.The advantage of such authentication method is that the human impedance was not easy to be stolen, and it was fully integrated with the hardware characteristics of the device (RFID tags), which greatly increased the difficulty for the attacker to copy and clone.To ensure the availability and efficiency of the system, an optimization authentication mechanism was proposed by cutting tag antenna, which effectively improved the impedance sensitivity.Moreover, the feasibility of passive drive was discussed by using the electromagnetic energy advantage of RFID system.Through a large number of experimental evaluations, the authentication accuracy of PBLock can reach 96%, and the average time cost of a single authentication is 1.4 seconds.Some attack models were presented based on practical environment.The results show that PBLock can effectively prevent counterfeiting attack, impersonation attack and replay attack, which provides an opportunity for the secure application of new biometric electronic locks.…”

Optimization and research on RFID anti-collision algorithm based on adaptive multi-dimension division code by Zhi-jin LI, Jie ZHOU, IAO-Jie Q, Wen-juan WU

“…Under the circumstance of many tags and many collisions,when multi-dimension division code algorithm is applied,the average number of times the reader calls each tag C(n) approximated to a limit 4/3,and the data conveyed by calling each tag tends to be a relatively small constant.However,under the circumstance of few collisions,the average number of times the reader calls each tag and the average data conveyed were relatively large.The adaptive multi-dimension division code algorithm,and the optimization of adaptive multi-dimension division code algorithm were proposed.The adaptive multi-dimension division code algorithm could adaptively decrease the MDDC dimensions according to the numbers of tags,and encode the tags again,hence greatly decrease the average number of times the reader calls each tag even under the circumstance of few tags.Therefore,in RFID system,adaptive multi-dimension division code algorithm can significantly improve the efficiency of searching for tags no matter in many collisions or in few collisions.…”

Text coverless information hiding method based on synonyms expansion and label delivery mechanism by Zhen ZHANG, Jiaming NI, Ye YAO, Lichun GONG, Yujuan WANG, Guohua WU

“…To solve the problems of low hiding capacity and weak detection resistance, a method of coverless information hiding based on synonyms expansion and label delivery mechanism was proposed.To begin the proposed method, the secret information were divided into several keywords, then those keywords were embedded in different carrier texts respectively.Considering the interchangeability of synonyms in Chinese, using the word similarity calculation method based on HowNet,it was possible to filter synonyms which met the contextual semantics.For the purpose of increasing hiding capacity, various keywords or their synonyms were embedded in the same carrier text as much as possible.At the same moment, when recording the positional parameters of the secret information in each carrier text, those parameters were converted into a binary sequence in a fixed format, which was used to generate carrier text.Finally, the carrier texts and generated text were sent to the receiver.Comparison of the results with those of other studies confirm that the proposed method not only makes great improvement in hiding capacity and detection resistance, but also reduces the overhead of establishing and maintaining databases by using small text database.…”
