Research and Application of the Formula for Calculating Discharge Coefficient of the Spillway Broad Crest Weir Based on the Binary Nonlinear Fitting by YAN Zhifang, JIA Yunfei, WANG Yu

“…In order to facilitate the use of the discharge coefficient table of broad crest weir in the current design code for Spillway of water conservancy,the discharge coefficient formula of broad crest weir is obtained by fitting the data in the current water conservancy code with bivariate rational function approximation.By Comparing the fitting formula with the current power code formula,the results show that the fitting formula is better than the current power code formula.By comparing the error indexes of fitting formula and power code formula,it is found that the error indexes of fitting formula are in the better range under each value of r/H,while the deviation of each error index of power code from the optimal value is small when r/H≥0.20.The fitting formula is used to calculate a series of discharge coefficients corresponding to water head at different fillet radii of a spillway broad crest weir.Through the analysis of the calculation results,it can be seen that the fitting formula can be used to calculate the discharge coefficient of broad crest weir in engineering design instead of consulting the water conservancy code table.…”

Massive access technology in 6G cellular Internet of things network by Feiyan TIAN, Xiaoming CHEN, Caijun ZHONG, Zhaoyang ZHANG

“…To realize Internet of everything (IoE),the 6G cellular Internet of things (IoT) network need to provide wireless access with low power,massive connectivity and wide coverage.Through the analysis and research on the massive access technology in 6G cellular IoT network,especially in combination with the sporadic characteristics of IoT applications,a new access framework based on the grant-free random access protocol was designed to facilitate efficient massive access with limited spectrum resources.The proposed framework consisted of two phases.One was joint activity detection and channel estimation.The other was data transmission,which was divided into two categories,uplink data transmission and downlink data transmission,according to the different directions of data transmission.Due to the uncertainty of channel state information at the base station under the massive grant-free random access and considering the low power demand of 6G IoT devices,two robust uplink and downlink access algorithms were designed by maximizing the system energy efficiency.Extensive simulation results validate the effectiveness and robustness of the proposed algorithm.…”

Construction method of attack scenario in cloud environment based on dynamic probabilistic attack graph by Wenjuan WANG, Xuehui DU, Dibin SHAN

“…Aiming at the problem of complex multi-step attack detection, the method of attack scenario construction oriented to cloud computing environment was studied.Firstly, a dynamic probabilistic attack graph model was constructed, and a probabilistic attack graph updating algorithm was designed to make it update periodically with the passage of time and space, so as to adapt to the elastic and dynamic cloud computing environment.Secondly, an attack intention inference algorithm and a maximum probability attack path inference algorithm were designed to solve the uncertain problems such as error and fracture of attack scenarios caused by false positive or false negative, and ensure the accuracy of attack scenario.Meanwhile, the attack scenario was dynamically evolved along with the dynamic probability attack graph to ensure the completeness and freshness of the attack scenario.Experimental results show that the proposed method can adapt to the elastic and dynamic cloud environment, restore the penetration process of attacker’s and reconstruct high-level attack scenario, and so provide certain references for building supervised and accountable cloud environment.…”
