Runoff Prediction Based on VMD-LSTM-ARMA Model by LUO Cankun, LIU Hao, HUANG Xin, SHAO Zhuang

“…To increase the accuracy of runoff prediction,a combined prediction model is proposed to solve the problems of runoff prediction.This model consists of the variational mode decomposition (VMD),long and short-term memory (LSTM) network,and autoregressive moving average (ARMA).To reduce the complexity of the incoming traffic,the runoff data is decomposed into three modal components with different frequencies by VMD.The low-frequency modal component inherits the temporal properties of the data and can be processed by constructing the LSTM prediction model,while the two high-frequency sequences are stationary time series and can be processed by constructing the ARMA prediction model.The prediction results of the three subsequences are superimposed to predict the runoff.Finally,the hourly flow data of Dongjiang Hydrometric Station of Xiangjiang river tributary in 2020 are used to forecast the inflow flow,and the results of comparative experiments with other algorithms show that the constructed model can effectively improve the accuracy of the hydrological forecast.…”

A bidirectional authentication protocol for RFID based on Syn by Shanhua ZHAN, Shaorong HUANG

“…The RFID system is made up of three parts:tags,readers and databases.The information between tags and readers are transmitted through wireless channel,which is easy to be intercepted by attackers.A two-way authentication protocol based on word Synthesis operation was proposed.The two remainder theorem was used to encrypt communication messages by the proposed protocol,the difficulty of cracking was increased; In the process of each round of communication encryption,a random number was added to make the communication messages inconsistent,so that the tracking attacks could not be initiated by attackers.In the communication message encryption,the word synthesis algorithms was adopted at the same time,the total calculation of the system could be effectively reduced.A random checking mechanism was introduced at the database,enabling a synchronous attack and other attacks to be effectively resisted by the system.Security analysis shows that the protocol has high security,and performance analysis shows that the protocol has the standard of lightweight computation.…”

Research on P2P streaming media identification based on UDP by Shi DONG, Gang WANG

“…Several popular P2P networks TV were studied,and their differences in port usage and packet size distribution were analyzed thoroughly.By observing the above characteristics,the conclusions that network TV application employs only one port to generate most of UDP traffic in one communicat period were summarized,and the UDP packet sizes in various network TV differ significantly.Thus,a method that can identify P2P application’s UDP traffic accurately and effectively was proposed based on extended flow records.Through identifying and verifying the five P2P streaming application traffic which was called Trace data collected from the backbone channel of CERNET (China education and research network) border in Jiangsu Province,and traffic identification results compared with machine learning algorithms show that the proposed method has a high precision rate and recall rate,high time efficient,and not susceptible to the impact of the proportion of the sample.…”

Prosodic organization of English folk riddles and the mechanism of their decoding by Larysa Taranenko

“…Within the process of cognitive model formation the author performs a conceptual analysis of the riddle compositional structure, presented as a systemic algorithmic scheme. It is confirmed that a characteristic feature of a folk riddle is its division into two elements: the first one is the description of an object, further differentiated into “topic” and “commentary”, while the second one is the riddle answer, or solution, generated directly in the recipient’s mind as a result of his/her mental activities. …”

Optimization strategy on coverage control in wireless sensor network based on Voronoi by Chun-jiang ZHAO, Hua-rui WU, Qiang LIU, Li ZHU

“…Coverage holes directly reduce network performance and become a key problem of wireless sensor network.A detect-repair scheme for area coverage in wireless sensor network with Voronoi was proposed.The strategy achieves the network coverage rate optimization balance with a prerequisite of an acceptable coverage quality of network area.It uses the geometry theories and vector algebra to analyse the sensing range of nodes and the position feature of Voronoi polygon.It can calculate the accurate area of holes and ensure the connectivity of networks with the least number of odes.Simulation results show that the strategy can effectively reduce number of the nodes and the overlapped sensing regions and control redundant nodes.Meanwhile,the strategy has fast convergence speed.It not only realizes the control and optimization of the network coverage,but also outperforms existing algorithms with respect to the coverage of the target region.…”

Task scheduling scheme based on improved particle swarm optimization with biological symbiosis mechanism in cloud computing by Linjie WANG

“…For the issues that the existing task scheduling scheme based on intelligent algorithms can’t obtain the optimal solution in cloud computing and inspired by nature symbiosis,a new task scheduling scheme based on improved particle swarm optimization(PSO)with biological symbiosis mechanism(SM)was proposed.Firstly,the particles in PSO were divided into two populations,and the optimization process were performed alone.Then,after each execution of the k iteration of PSO,the individual in the two populations performed the mutualism and parasitism operation.The search process was optimized by mutualism operation to through the optimal solution region,which could enhance the search ability.The parasitism operation was used to avoid premature convergence by eliminating the poor and introducing the optimal solution.Finally,the optimal solution of the task scheduling was obtained.Simulation results show that the optimal scheduling scheme can obtain the minimum task completion time and response time.…”
