Applied Sciences, Vol. 16, Pages 8618: Frequency-Selective Station Diagnostics for Diffuse Volcanic Degassing: Integrating Soil-Gas Flux with Paired-Depth Pressure and Temperature Measurements

2+ week, 1+ day ago   (409+ words) Diffuse volcanic-degassing stations record environmental and instrument-driven variability across minutes to seasons. A flux record alone does not identify which forcing components reach the monitored layer or whether the acquisition chain alters them. We present a local three-channel diagnostic integrating…...

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

2+ week, 6+ 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 7980: Numerical Investigation of Drilling Process for Complex Polar Ice Interlayers: An F-DEM Study

1+ mon, 2+ day ago   (487+ words) Subglacial drilling through polar ice–rock transitional zones is frequently hindered by severe load fluctuations and instability induced by strong formation heterogeneity. This study investigates the coupled drilling mechanics across pure ice, an ice–rock mixture, and bedrock using a…...

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,…...
