Rapid screening and optimization of CO2 enhanced oil recovery operations in unconventional reservoirs: A case study
Published 2025-04-01“…Based on the results of model interpretability, the genetic algorithm (GA) was coupled with RF (RF-GA model) to optimize the CO2-EOR process. The proposed framework was validated by comparing the GA-RF predictions with simulation results under different reservoir conditions, which yielded a minimum relative error of 0.34% and an average relative error of 5.3%. …”

Market Efficiency and Stability Under Short Sales Constraints: Evidence from a Natural Experiment with High-Frequency Resolution
Published 2025-02-01“…Firstly, we derive the theoretical price with put–call parity from seven series index options. Using a “threshold error correction model” (TECM), we find a more efficient price adjustment to new equilibria for upward adjustments than for downward adjustments. …”

Optimal payload lengths of reliable multicast schemes
Published 2011-01-01“…Using total transmission time-the time needed to guarantee reliable data dissemination——as judgment criterion,the payload length selection problem was investigated for three multicast solutions which are based on simple feedback retransmission,Reed-Solomon codes,and LT fountain codes,respectively,with the consideration of packet overhead.A theoretical analysis method was proposed to determine the optimal payload lengths,which was verified by simulations.Analyses and simulations indicate,for variable packet overhead sizes and link bit error rates,each method considered has its optimal payload length.As link bit error rate increases,the performance gain brought by the selection of optimal pay-load lengths becomes more significant.Among the three solutions,the reliable multicast solution based on LT fountain codes has the most outstanding performance.…”

Friction stir welding tool trajectory error on the load capacity of EN AW-2024-T3 aluminum alloy joints
Published 2025-12-01“…Since the FSW-capable robot has low stiffness, a HAAS TM1P milling machine was used to simulate the robot's motion, incorporating recorded deviation errors. The welding process of 1 mm thick sheets was first conducted under ideal rectilinear conditions, establishing optimal parameters: feed rate of 200 mm/min, tool rotational speed of 1517 rpm, and plunge depth of 1.46 mm. …”
