Parallel sequential pattern mining on distributed system

, 2010
碩士本研究以提昇循序樣本探勘效率為目標，發展了一套結合多部電腦的分散式探勘系統。首先，由於直接以支持度預測子任務工作量並不準確，我們提出新的工作量預測方法。而後，本研究提出了一套負載平衡演算法-ADLB，結合動態與靜態分配的特點，對於任務採取分段分配，以達成負載平衡並降低通訊負擔。此外，我們也引用並改進文獻[20]中有關演算法切換的概念，以取得更大幅度效能改善。為驗證系統效能，我們結合了16部電腦進行分散式探勘，實驗結果顯示，本系統在各種不同節點數目下均具有良好加速比，顯示其具有處理大型資料之潛力 ...

Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

Advanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

Advanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...

Decoupling Intrinsic Molecular Efficacy From Platform Effects: An Interpretable Machine Learning Framework for Unbiased Perovskite Passivator Discovery

Advanced Science, EarlyView.
This study establishes an interpretable machine learning framework that disentangles the intrinsic molecular efficacy of passivators from experimental platform effects—enabling unbiased, high‐throughput discovery of effective perovskite surface modifiers.
