Discharge Characteristics of Bubbles at Interface Between AlN Ceramic and FC-72 Liquid

Autor: Shenyang Mo, Xuebao Li, Zhibin Zhao, Xiang Cui

Publikováno v: CSEE Journal of Power and Energy Systems, Vol 10, Iss 1, Pp 371-380 (2024)

In order to evaluate the insulation of two-phase immersion cooling in the HV power electronic package, the insulation degradation of the dielectric interface induced by bubbles is investigated. In this paper, a test strategy with 50 Hz unipolar DC an

Achieving optimal trade-off for student dropout prediction with multi-objective reinforcement learning

Autor: Feng Pan, Hanfei Zhang, Xuebao Li, Moyu Zhang, Yang Ji

Publikováno v: PeerJ Computer Science, Vol 10, p e2034 (2024)

Student dropout prediction (SDP) in educational research has gained prominence for its role in analyzing student learning behaviors through time series models. Traditional methods often focus singularly on either prediction accuracy or earliness, lea
