Analysis of No.1 Flood Disaster in Poyang Lake Basin in 2020 Based on Natural Disaster System Theory
Published 2022-01-01“…China is one of the countries most hit by flood disasters in the world.Flood disasters have the highest frequency,are distributed in the widest scope,and cause the largest loss in China.It is of great guiding significance to analyze the characteristics of disaster system elements for a better understanding of the evolution process of flood disasters.This study collects the disaster-formative environment (topography and river network),disaster-bearing body (socioeconomy),disaster-inducing factor (daily rainfall),and disaster losses in the core area of the Poyang Lake Basin.Moreover,it investigates the disaster mechanism and evolution process of the No.1 flood disaster in the Poyang Lake Basin in 2020 and discusses the flood prevention and control measures for the Poyang Lake Basin.The results show that the high-intensity rainfall since June was the precondition of the No.1 flood disaster in 2020 in the Poyang Lake Basin,which led to almost saturated soil moisture.Under the joint action of extremely heavy rainfall from 1 to 8 July (strong disaster-inducing factor) and low elevation (high sensitivity of disaster-formative environment) in the core area of the Poyang Lake Basin,the floods spread quickly and flooded the socioeconomic system (disaster-bearing body) of the lake area in a short time.Case analyses of typical flood disasters from the perspective of disaster systems will help improve the capabilities for risk identification,disaster prevention,and disaster mitigation of regional flood disasters.…”

Ineffectiveness of phosphorus binding treatments in a semi-enclosed area of a large, shallow, and hypereutrophic lake
Published 2025-01-01“…We evaluated these applications by comparing total phosphorus (TP), total microcystin, total chlorophyll, and phycocyanin concentrations within the enclosure and the adjacent lake. Some evidence for short-term reductions in TP, microcystin, chlorophyll, and phycocyanin concentrations were observed following each P binding treatment, but all parameters rapidly returned to or exceeded pre-application levels within 2–3 weeks after treatment. …”

Sensitivity and Uncertainty Analysis of the Maximum Fuel Temperature under Accident Condition of HTR-PM
Published 2020-01-01“…The numerical results indicate that the pebble-bed effective conductivity and the decay heat contribute the most of the uncertainty in the DLOFC maximum fuel temperature while this peak fuel temperature is most sensitive to the initial reactor power and the decay heat. In short, uncertainties in these selected eight parameters lead to the two standard deviation (2σ) uncertainty of ±77.6°C (or 5.2%) around the mean value of 1493°C for the maximum fuel temperature under DLOFC accident of HTR-PM. …”

Design of concatenated Hash-Polar code based on segmented CRC code
Published 2022-07-01“…As a linear block code, the polarization code has a lower coding complexity and a definite structure, but when it has a short or medium code length, the performance will be reduced.A design method of concatenated HashPolar codes based on segmented cyclic redundancy check (CRC) codes was proposed, which was based on the original Hash-Polar code and used CRC segmented check for double check.The segmented CRC code could assist the path measurement in the decoding process, that was, modify the decoding path, so as to improve the reliability of path selection and the performance.In addition, the segmented check was to add the check code dispersedly to the input information sequence.If the CRC failed during decoding, the decoding path could be terminated in advance to save unnecessary decoding calculations.Finally, at the end of the decoding, Hash check code verified the modified L paths and selected the best decoding path.The simulation results show that the design method proposed has better bit-error-rate performance than CRC-assisted Hash-Polar (Hash-CRC-Polar).In the Gaussian channel, when the code length is 128 bit, the code rate is 1/2, and the bit error rate is 10<sup>-3</sup>, the Hash-Polar code based on the segmented CRC code proposed achieves a gain of about 0.25 dB over Hash-CRC-Polar.…”
