Cause Analysis and Control Measures of Waterlogging in Shanghai Zoo Based on MIKE 21 by ZHOU Jing, WANG Huan

“…In order to analyze the cause of waterlogging after the drainage system of Shanghai Zoo reached the standard and explore the best control measures,data analysis and field investigation were carried out,and it was preliminarily determined that the waterlogging in the zoo was related to the poor drainage of the water system and the insufficient drainage pumping station.MIKE 21 was used to build a hydrodynamic model of the water system in the zoo,and the changes in the hydrological characteristic values of the water system under the current drainage condition were simulated and studied.It is concluded that the root cause of waterlogging in the zoo is that the drainage path is blocked,and the drainage pumping station has an insufficient scale and unreasonable layout.In order to promote drainage and remove waterlogging,the water system optimization and waterlogging facility renovation plans were proposed,and the engineering effect of each plan was simulated.Through the comparison of indicators such as drainage rate,drainage time,and maximum drainage time difference in different regions,the effect of each plan in promoting drainage and removing waterlogging was determined.In view of the engineering economy,the plan of expanding culverts and moving some culverts to the river was determined as the best,and the drainage layout was adjusted to achieve the best control effect under the specific investment.…”

FPGA multi-unit parallel optimization and implementation of post-quantum cryptography CRYSTALS-Kyber by Bin LI, Xiaojie CHEN, Feng FENG, Qinglei ZHOU

“…In lattice-based post-quantum cryptography, polynomial multiplication is complicated and time-consuming.In order to improve the computational efficiency of lattice cryptography in practical applications, an FPGA multi-unit parallel optimization and implementation of post-quantum cryptography CRYSTALS-Kyber was proposed.Firstly, the flow of Kyber algorithm was described and the execution of NTT, INTT and CWM were analyzed.Secondly, the overall structure of FPGA was given, the butterfly arithmetic unit was designed by pipeline technology, and the Barrett modulus reduction and CWM scheduling optimization were used to improve the calculation efficiency.At the same time, 32 butterfly arithmetic units were executed in parallel, which shortens the overall calculation cycle.Finally, the multi-RAM channel was optimized to improve the memory access efficiency with alternate data access control and RAM resource reuse.In addition, with the loosely coupled architecture, the overall operation scheduling was realized by DMA communication.The experimental results and analysis show that the proposed scheme implemented can complete NTT, INTT and CWM operations within 44, 49, and 163 clock cycles, which is superior to other schemes and has high energy efficiency ratio.…”

xStripeMerge: efficient wide stripe generation approach based on erasure coding storage by Meiguang ZHENG, Taofei HUA, Xinyu ZHANG, Zhigang HU

“…To address the issue of wide stripe generation in existing erasure coding storage systems, where storage scaling approaches resulted in a significant increase in wide stripe generation bandwidth and stripe merge scheme was constrained by dual-stripes, an efficient wide stripe generation approach was proposed for the wide stripe generation problem under multi stripes merging.Two key operators for the multi-stripes merging progress were defined, and the wide stripe generation problem was modeled as a combinatorial optimization problem.The efficient wide stripe generation approach xStripeMerge was proposed that prioritize the search for narrow-stripes combining schemes with small parity block transmission costs.Experimental results show that xStripeMerge can reduce the wide stripe generation bandwidth by 75% compared to the advanced storage scaling method.The time and space complexity of xStripeMerge is much better than that of the extended dual-stripes merge approach.xStripeMerge can get the wide stripe generation scheme with similar performance in a shorter period of time and it is also suitable for large-scale storage systems.…”

Dynamic cache allocation routing strategy of Internet of things satellite node based on traffic prediction by Weidong WANG, Cheng WANG, Huiwen WANG, Pin XU

“…Aiming at the routing problem of low earth orbit (LEO) Internet of things (IoT) satellite systems,a dynamic cache allocation routing strategy based on traffic prediction for IoT satellite nodes was proposed.Firstly,the space-time characteristics of traffic distribution in the LEO coverage area were analyzed,and an end-to-end traffic prediction model was proposed.Then,according to the traffic prediction result,a dynamic cache allocation routing strategy was proposed.The satellite node periodically monitored the traffic load of the inter-satellite link,dynamically allocated the cache resources of each inter-satellite link between the neighboring nodes.The cache allocation process was divided into two phases,initialization and system operation.At the same time,the traffic offload and packet forwarding strategy when the node was congested was proposed.By comparing the queuing delay and the forwarding delay,it was determined whether the data packet needs to be rerouted.The simulation results show that the proposed routing strategy effectively reduces the packet loss rate and average end-to-end delay,and improves the traffic distribution in the whole network.…”
