Investigation of the Law of Natural Gas Phase Behavior during the Migration and Reservoir Formation by Longlong Li, Jiaren Ye, Minqi Li, Lin Pan

“…Using this model, we found that if the free-phase natural gas accumulated in the DF1-1 structural reservoir is completely dissolved in the water-soluble phase, the required formation water volume is much higher than the actual calculated formation water storage. Therefore, it can be inferred that the natural gas generated from the source rock of the DF13-1 structure mainly migrated and accumulated in the form of the free phase.…”

Edge computing privacy protection method based on blockchain and federated learning by Chen FANG, Yuanbo GUO, Yifeng WANG, Yongjin HU, Jiali MA, Han ZHANG, Yangyang HU

“…Aiming at the needs of edge computing for data privacy, the correctness of calculation results and the auditability of data processing, a privacy protection method for edge computing based on blockchain and federated learning was proposed, which can realize collaborative training with multiple devices at the edge of the network without a trusted environment and special hardware facilities.The blockchain was used to endow the edge computing with features such as tamper-proof and resistance to single-point-of-failure attacks, and the gradient verification and incentive mechanism were incorporated into the consensus protocol to encourage more local devices to honestly contribute computing power and data to the federated learning.For the potential privacy leakage problems caused by sharing model parameters, an adaptive differential privacy mechanism was designed to protect parameter privacy while reducing the impact of noise on the model accuracy, and moments accountant was used to accurately track the privacy loss during the training process.Experimental results show that the proposed method can resist 30% of poisoning attacks, and can achieve privacy protection with high model accuracy, and is suitable for edge computing scenarios that require high level of security and accuracy.…”

Carrying Capacity Evaluation of Water Resources in Jiangsu Province Based on PSR Model-Comprehensive Weighting Method by LI Zhijun, WANG Chao

“…According to the economic and social development and conditions of water resources in Jiangsu Province,this paper established a pressure-state-response evaluation index system based on the PSR model and determined index weight based on the comprehensive weighting method combining entropy weight method with AHP.In addition,the paper calculated the relative closeness based on the TOPSIS model and comprehensively evaluated the carrying capacity of water resources in Jiangsu Province from 2011 to 2019.The results show that the carrying capacity of water resources in Jiangsu Province from 2011 to 2019 always maintained at a medium level,and the relative closeness fluctuated between 0.4 and 0.6,with the maximum and minimum values being 0.582 in 2014 and 0.406 in 2015,respectively.After 2015,the relative closeness increased again.Furthermore,in the next four years,although the relative closeness fluctuated,the amplitude was slight,and the value varied between 0.45 and 0.47.As a result,it indicates that the carrying capacity of water resources in Jiangsu Province has tended to be stable and gradually developed positively.…”
