Mineral exploration gets artificial intelligence boost
1+ day, 16+ hour ago (407+ words) China unveiled geological mapping and mineral exploration systems powered by artificial intelligence technologies on Friday, marking a shift from decades of expert-driven fieldwork to more accurate, comprehensive and efficient data — and algorithm-based predictions. The two systems — AI-GeoMapping and AI-OreSeeking — were…...
Parabolic SAR Constraint Kinematics & Run Geometry — Indicator by SG_Group
5+ day, 57+ min ago (119+ words) Overview Parabolic SAR Constraint Kinematics & Run Geometry studies how a continuing Parabolic SAR step is formed and how the surrounding run develops. It keeps TradingView's ta.sar() as the plotted SAR series and adds measurements of the run's Extreme Point,…...
Applied Sciences, Vol. 16, Pages 8812: Optimised Machine Learning for MASW-Based Zonation of Weak Alluvial Soils Using Anchor-Based SPT/SCPT Calibration
1+ week, 1+ day ago (433+ words) Weak alluvial soils are difficult to delineate where penetration-test data are sparse and stiffness varies rapidly with depth. This study presents a novel goal-attainment-optimised machine learning framework that combines multichannel analysis of surface waves (MASW) with anchor-based standard penetration test…...

China uses AI to map Earth’s deep mantle
1+ week, 5+ day ago (374+ words) Deep beneath Earth’s surface, at a depth of nearly 2,900 kilometers, the mantle gives way to the liquid outer core. The dynamics of these extreme depths influence tectonic plate movements and contribute to earthquakes and volcanic eruptions. Yet directly studying these…...
Quiescent core in turbulent channel flow with spanwise-uniform roughness | Journal of Fluid Mechanics
2+ week, 18+ hour ago (367+ words) This study examines drag and outer-layer similarity in a rough-wall channel with spanwise-uniform bars at pitch-to-height ratios 6, 12 and 24, using direct numerical simulations at. The quiescent core (QC) is detected via kernel density estimation of the streamwise velocity probability density function…...
P1-KAN: An Effective Kolmogorov-Arnold Network for Hydraulic Valley
2+ week, 1+ day ago (71+ words) A new artificial-intelligence architecture designed to handle the jagged, unruly mathematics of real-world systems has outperformed both conventional neural networks and established optimization software in a demanding test involving a French hydraulic valley. Called P1-KAN, the model is a new…...
