Study on the Relationship Between Water Resources Utilization and Economic Development in Hubei Province
Published 2023-01-01“…According to the water footprint theory,the structural characteristics of water footprint and the level of water resources utilization in Hubei Province were analyzed.The analysis results show that:①The water footprint and agricultural water footprint in Hubei Province generally rise with fluctuations,while the industrial water footprint decreases with fluctuations.The agricultural water footprint accounts for 87.8% of the water footprint in the province,which indicates that the water footprint in Hubei Province has significantly different structures.②The water resources utilization and economic growth in Hubei Province show a weak decoupling trend.The economy of Hubei Province develops positively,and the industrial structure is reasonable.The technical effect and economic scale cause major waste of water resources.③The overall water footprint intensity in Hubei Province significantly drops,and the water resources utilization efficiency gradually improves.However,the water footprint intensity in some regions is relatively high,and the water resources utilization efficiency can still be improved.④The water footprint intensity in Hubei Province has a significant spatial autocorrelation,which mainly presents low-low and high-low spatial clustering patterns,and it has an obvious tendency to spread to the surrounding areas.…”

Resource Allocation of Multi-Satellite Beam Hopping Technology Based on System Capacity Maximization
Published 2022-12-01“…Unlike medium and high earth orbit satellites, LEO satellites have the characteristics of small path loss, low propagation delay and high deployment fl exibility.LEO satellites are widely used in real time services, global internet of things, emergency communication and other fi elds.In order to solved the problems of large diff erences in service demand distribution of terrestrial users and low resource utilization in LEO satellite communication systems, a resource allocation algorithm of LEO multi-satellite beam hopping technology based on convex optimization was proposed, which aimed to maximized the system capacity.For multisatellite beam hopping scenarios in LEO satellite communication system, the beam-hopping technology could fl exibly allocated system resources accorded to user needs.Considered the factor of co-channel interference, the service region division scheme based on load balancing and the inter-satellite resource allocation priority scheme was proposed.In order to improved system capacity and resource utilization, it jointly designed a time and power resource allocation algorithm based on convex optimization.The simulation results showed that the proposed scheme could eff ectively reduced co-channel interference and realized the ondemand allocation of system capacity without causing waste of resources.…”

Crowd-based collaboration caching mechanism in smart identifier network
Published 2018-12-01“…Smart identifier network (SINET) is an innovative network architecture.Through dynamic collaboration of service resource,function groups and physical components,the network scalability,resource utilization and service quality were effectively improved by SINET,and an effective solution for the development of industrial Internet of things(IoT) could be provided.To promote content delivery in resource-constrained IoT,caching function was introduced in network components by SINET,and the bandwidth waste caused by traffic redundancy in resource-constrained node could be reduced.Therefore,how to efficiently cache content became an important research topic.Based on SINET architecture,a crowd-based collaboration cache (C2Cache) mechanism was proposed in this scheme.According to the actual network topology,the caching function group was dynamically created and optimized by C2Cache,and a function group as crowd minimum unit to execute the maximum benefit cache (MBC) algorithm was defined to maximize the caching space efficiency.With the self-developed emulation system,named EmuStack,the performance of C2Cache was evaluated.The experimental results show that,comparing with LCE,Random,Prob Cache,LCD and Greedy caching mechanisms,the cache hit rate can be improved effectively,then the average access time can be reduced significantly by C2Cache.In the simulated network scenario,the performance increases 15% to 30%.…”

Secure and verifiable multi-keyword searchable encryption scheme in cloud
Published 2021-04-01“…Due to the advantages of cloud computing, such as virtualization and high scalability, individuals and enterprises are willing to outsource local data storage and computing to cloud servers.However, encryption breaks the linkability between the data.Although searchable encryption (SE) enables cloud servers to provide retrieval services of the encrypted data for data owners, cloud servers who are untrusted, may tamper and delete data, or learn information of the newly added encrypted files with previous trapdoors.Besides, single-keyword search inevitably incurs many unrelated results, resulting in a waste of bandwidth and computing resources.To address the problems above, an efficient and verifiable multi-keyword search encryption scheme was proposed, which could not only supported multiple-keyword search, but also realized the privacy of search pattern and forward security of the outsourced files.In the meanwhile, it also ensured the integrity check of the outsourced data.Through rigorous security verification, the proposed scheme was proved to be secure under the standard mode, and could resist offline keyword guesswork attack (KGA) on untrusted cloud servers.Finally, by comparing the efficiency and performance with the recent three searchable encryption schemes, the experimental results show that the proposed scheme has the best comprehensive performance in terms of function and efficiency among the four schemes.…”
