SRESS AND FATIGUE LIFE OF PITTING DEFECTS ON PUMPING UNIT GEAR by BAI YunSong, MUTELLIP AhMat, BAI HaoYu, CHEN Zhi

“…In order to analyze the pitting damage and fatigue life of gear in rack-and-pinion pumping unit, Firstly, the model of rack-and-pinion was established, the elements of tooth surface and root were extracted for static strength analysis, and then compared with contact theory; Secondly, Pitting defects of different sizes were established by elements editing, and the influence of pitting growth on contact stress was analyzed; Finally, fatigue life under different pitting effects was calculated based on linear fatigue damage theory. The results show that with the growth of pitting defects, the contact stress increases and the fatigue life decreases; The pinion interference occurs in the transition section, the stress concentration is worst, and the fatigue life is low, the overall fatigue damage starts from the tooth top; The pitting extend along the tooth profile direction mainly affects the duration of stress concentration, and along the tooth width mainly affects the amplitude of stress change.…”

Research on flood defense mechanism of SDN control layer:detection and mitigation by Qizhao ZHOU, Junqing YU, Dong LI

“…Aiming at the problem of spoofing flood defense in the control layer of SDN, a controller defense mechanism (CDM)was proposed, including a flood detection mechanism based on key features multi-classification and a flood mitigation mechanism based on SAVI.The flood feature analysis module of the control layer was designed for flood detection, and boosting algorithm was used to overlay each feature weak classifier to form an enhanced classifier, which can achieve more accurate classification spoofing flooding attack effect by continuously reducing the residual in the calculation.In CDM, a flood mitigation mechanism based on SAVI was deployed to realize flood mitigation, which performed flood packet path filtering based on binding-verification mode, and updated the flood features of access layer switches with dynamic polling mode to reduce redundant model update load.The experimental results show that the proposed method has the characteristics of low overhead and high precision.CDM effectively increases the security of the control layer, and reduces the time of host classification of spoofing flood attack and the CPU consumption of corresponding controller.…”

Privacy-protected crowd-sensed data trading algorithm by Yong ZHANG, Dandan LI, Lu HAN, Xiaohong HUANG

“…To solve the problem that data privacy leakage of participants under the crowd-sensed data trading model, a privacy-protected crowd-sensed data trading algorithm was proposed.Firstly, to achieve the privacy protection of participants, an aggregation scheme based on differential privacy was designed.Participants were no longer needed to upload raw data, but analyzed and calculated the collected data according to the task requirements, and then sent the analysis results to the platform after adding noise in accordance with the privacy budget allocated by the platform to protect their privacy.Secondly, in order to ensure the credibility of participants, a reputation model of participants was proposed.Finally, in order to encourage consumers and participants to participate in transactions, a data trading optimization model was constructed by considering the consumer’s constraint on the result deviation，the participant’s privacy leakage compensation and platform profit, and a POA based on genetic algorithm was proposed to solve the model.The simulation results show that the POA not only protects the privacy of participants, but also increases the profit of the platform by 29.27% and 20.45% compared to VENUS and DPDT, respectively.…”

“…In view of the nonlinear, stochastic and sudden characteristics of operating environment of cloud server system, a software aging prediction method based on hybrid auto-regressive integrated moving average and recurrent neural network model (ARIMA-RNN) was proposed.Firstly, the ARIMA model performs software aging prediction of time series data in cloud server.Then the grey relation analysis method was used to calculate the correlation of the time series data to determine the input dimension of RNN model.Finally, the predicted value of ARIMA model and historical data were used as the input of RNN model for secondary aging prediction, which overcomes the limitation that ARIMA model has low prediction accuracy for time series data with large fluctuation.The experimental results show that the proposed ARIMA-RNN model has higher prediction accuracy than ARIMA model and RNN model, and has faster prediction convergence speed than RNN model.…”
