Introducing Glaciohydrological Model Calibration Using Sentinel‐1 SAR Wet Snow Maps in the Himalaya‐Karakoram

open access: yesWater Resources Research
Field‐based studies are limited in Himalaya‐Karakoram (HK); therefore, remote sensing and glaciohydrological modeling provide alternative solutions to investigate runoff evolution under changing climate conditions.

Allometric relationships between total height and diameter for volume estimation of bottomland hardwood oaks in Arkansas

open access: yesFrontiers in Forests and Global Change
Bottomland hardwood (BLH) forests are a unique ecosystem that plays an important role in the provision of ecosystem services, both ecologically and economically. This study modeled allometric relationships between total tree height and diameter at breast

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Constraining 2D Hydrogeological Inversion With 3D Lithological Data

open access: yesWater Resources Research
In hydrogeology, piezometric data are the key constraints for model calibration. Their limits for three‐dimensional (3D) parameterization have often been pointed out, with water heads commonly regarded as having too little sensitivity to vertical ...

Does Updating Driving Factors Improve Land-Use Simulation? A Controlled Comparison of Target-Driven Versus Baseline-Driven CLUE-S Modeling in Xiamen, China

open access: yesLand
Conventional applications of the CLUE-S model rely on a static driver assumption, using driver data and their associated coefficients from a base year to simulate land-use patterns for a future target year—an approach that implicitly assumes temporally ...

TerraSAR-X Calibration Ground Equipment

open access: yes, 2007
The Microwaves and Radar Institute regularly performs calibration campaigns for spaceborne SAR systems, among which have been X-SAR, SRTM, and ASAR. In 2007, the German SAR satellite TerraSAR-X will be launched.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Calibration for Stratified Classification Models

open access: yesCoRR, 2017
In classification problems, sampling bias between training data and testing data is critical to the ranking performance of classification scores. Such bias can be both unintentionally introduced by data collection and intentionally introduced by the algorithm, such as under-sampling or weighting techniques applied to imbalanced data. When such sampling
