Applied Sciences, Vol. 16, Pages 8845: Characterization of Geothermal Reservoir Structures Based on a Deep Generative Neural Network with Local Edge Pattern Learning

1+ week, 17+ hour ago   (420+ words) Accurate three-dimensional (3D) characterization of geothermal reservoirs is crucial for resource assessment and development, yet it remains a significant challenge due to sparse direct observations and the complex, heterogeneous nature of subsurface geology. While deep learning has emerged as a powerful…...

Applied Sciences, Vol. 16, Pages 8408: Model Test on Thermo-Mechanical Behavior of Pure Friction Piles Under Cyclic Temperature

2+ week, 5+ day ago   (477+ words) Frictional energy piles are a more desirable form of shallow geothermal energy utilization. A pure friction pile condition cannot be achieved in field tests. In this study, foam was placed beneath the model pile tip to weaken the end-bearing resistance....

Applied Sciences, Vol. 16, Pages 7950: Numerical Analysis of Hydraulic Fracture Propagation Behaviors in Ultra-Deep Lattice-like Fractured Reservoirs

1+ mon, 2+ day ago   (447+ words) Ultra-deep lattice-like fractured carbonate reservoirs, formed by multi-period tectonic movements, feature strong heterogeneity, multi-scale fracture nesting, and anisotropic in situ stress. However, hydraulic fracture (HF) propagation behaviors within these complex formations remain poorly understood. In this study, using an unstructured…...

Applied Sciences, Vol. 16, Pages 7818: Target-Protected Multiscale GLRT-CUSUM Detection for Low-SNR Vector Magnetic Anomalies on Ocean Buoys

1+ mon, 1+ week ago   (372+ words) Vector magnetic anomaly detection on ocean buoys is challenged by attitude changes, non-stationary backgrounds, and weak targets that adaptive filters may absorb. We propose an online target-protected framework combining attitude compensation, constant-false-alarm-rate normalized innovation squared (CFAR-NIS) threshold adaptation, target-dwell gating,…...
