This study addresses the limitation of traditional kiln roofs,which are typically designed for specific kilns,by developing a movable roof compatible with most ceramic kilns.It also incorporates a 5G private network communication framework for data transmission,optimizes cloud server communication protocols,and enables remote,lowlatency batch control of the roof within enterprise campuses.The system consists of the kiln roof,a temperature controller,a data transfer unit(DTU),and a cloud server.It allows for setting temperature thresholds to automatically raise or lower the roof,as well as realtime temperature monitoring via DTU for remote manual control.The cloud server records historical data on roof operations and corresponding temperatures.Experimental results demonstrate that the movable kiln roof effectively achieves its intended objectives,reducing kiln manufacturing costs,minimizing labor requirements,and enhancing the intelligent operation of ceramic kilns. 展开更多

Power consumption of the 5th generation mobile communication technology(5G)mobile networks has become a critical issue due to high power consumption and dense deployment of base stations(BSs).This problem is even more pronounced in railway scenarios,where traffic patterns exhibit strong burstiness and BSs face prolonged idle periods along the railway.Despite this,there is currently no effective and comprehensive solution that integrates multiple energy-saving strategies.Therefore,it is essential to design specific energy-saving schemes applied to the railway scenarios.This paper proposes a joint multivariate energy-saving approach with multiple time granularities for the private 5G networks for railways(5G-R).Specifically,it formulates an energy minimization problem involving the joint optimization of BS sleeping,remote radio unit(RRU)sleeping,antenna selection,and symbol shutdown under quality of service(QoS)constraints according to the railway traffic.Given that the response cycle of each strategy differs,a hierarchical energy-saving optimization scheme with multiple time granularities is employed.Additionally,a heuristic approach based on genetic algorithm(GA)is proposed to successively solve the energy minimization problem at each time granularity.Simulation results demonstrate that the proposed scheme significantly reduces power consumption in 5G-R systems,achieving up to 50.4%energy savings while meeting network traffic demands. 展开更多

A multi-homed VPN architecture based on extended SOCKSv5 and TLS was proposed. The architecture employs a dynamic connection mechanism for multiple proxies in the end system,i n which the security-demanded transmission connections can switch smoothly among the multiple proxies by maint aining a coherent connection context.The mechanism is transparent to application programs and can support th e building of VPN.With the cooperation of some other security components,the mechanism guarantees the reso urce availability and reliability of the end system against some attacks to the specific ports or hosts. 展开更多
