Extrapolation-Aware Gaussian Process Configuration for Small-Sample Complex-Equipment Cost Estimation

Complex-equipment cost estimation often relies on very small historical datasets, and new targets may fall partly outside the feature ranges represented by those data. This study examines whether two observable data-state indicators can provide a transparent basis for configuring...

An integrated remote sensing framework reveals zone-specific ecological response trajectories to open-pit mining on the Qinghai-Tibet plateau

Rapid mining expansion on the Qinghai-Tibet Plateau threatens its fragile alpine and arid ecosystems, with complex and spatially heterogeneous impacts, underscoring the need for long-term quantitative monitoring to support effective management. To address gaps in prior work that...

Prioritizing key performance indicators for maintenance management in public hospitals: a hybrid SEM–machine learning approach

Purpose Public hospital maintenance operates under growing service pressure, yet existing frameworks often rely on data-intensive systems or broader facility outcomes, offering limited guidance on which maintenance key performance indicators (KPIs) should be prioritized under res...
