Site characterization of reclaimed lands based on seismic cone penetration test by Wang, Hao, Wu, Shifan, Qi, Xiaohui, Chu, Jian

“…The derived correlations for the fill materials are found to be significantly different from those proposed for intact soils in literature, mainly due to the difference in geological history and material composition. The application of the new correlations is illustrated through three independent case studies. …”

Opportunities for machine learning to accelerate halide-perovskite commercialization and scale-up by Kumar, Rishi E., Tiihonen, Armi, Sun, Shijing, Fenning, David P., Liu, Zhe, Buonassisi, Tonio

“…In this perspective, we review practical challenges hindering the commercialization of halide perovskites, and discuss how machine-learning (ML) tools could help: (1) active-learning algorithms that blend institutional knowledge and human expertise could help stabilize and rapidly update baseline manufacturing processes; (2) ML-powered metrology, including computer imaging, could help narrow the performance gap between large- and small-area devices; and (3) inference methods could help accelerate root-cause analysis by reconciling multiple data streams and simulations, focusing research effort on areas with highest probability for improvement. …”
