An Improved Gaussian Mixture Model-Based Data Normalization Method for Removing Environmental Effects on Damage Detection of Structures
Published 2025-01-01“…Next, on the basis of the constructed GMM, the modal frequency data are normalized to extract damage features that remain unaffected by environmental variations. Subsequently, Hotelling’s T2 statistic and its cumulative form are calculated for the damage features and designated as the damage indicators; meanwhile, the corresponding damage thresholds are also calculated according to the kernel density estimation technique. …”

Spatiotemporal evolution of landscape ecological risk and its driving factors of the Beijing–Tianjin–Hebei major mineral belt, 1985–2022
Published 2025-01-01“…The ‘high-high’ aggregations are primarily located in the northern, central and western parts of the study area, while the ‘low-low’ aggregation zones are mainly located in the southeastern study region. (4) The spatial distribution of landscape ecological risk is predominantly shaped by population density and slope. In the context of interactive factor detection, the positive interaction between slope and average annual temperature, night-time illumination and slope, population density and annual precipitation were identified as exerting a more significant influence on the observed spatial differentiation of landscape ecological risk. …”

UAV LiDAR expands the understanding of forest tree diversity
Published 2025-06-01“…The results revealed that (1) the diversity indices calculated with importance value correlate better with LiDAR features than with relative density; (2) among heterogeneity metrics, Rao’s Q outperformed the coefficient of variation (CV), and heterogeneity metrics overall performed better than structural features in estimating tree diversity; (3) the LiDAR data provided fine-scale structural information, with the highest accuracy for estimating tree diversity achieved at a 1 m spatial resolution; and (4) features from the cover category, including canopy cover (CC), cover of the herbaceous layer (CH), and cover of the tree layer (CT), demonstrated greater robustness and stronger correlations with tree diversity across different spatial resolutions. …”
