    A Conditional Simulation Method for Predicting Wind Pressure Fields of Large-Span Spatial Structures by Fangjin Sun, Tiantian Liu, Daming Zhang, Zhonghao Xu

    Published 2021-01-01
    “…However, due to the limited wind pressure data obtained from wind tunnel testing, it is quite meaningful to employ the limited measured data to predict the unknown wind pressure at target points. Considering the complexity of wind pressure fields of large-span spatial structures, a simplified nonparametric method based on conditional simulation is proposed to predict the unknown pressures using the existing data. …”

    A Quality Soft Sensing Method Designed for Complex Multi-process Manufacturing Procedures by Kaixiang PENG, Xin QIN, Jiahao WANG, Hui YANG

    Published 2024-11-01
    “…Both XGBoost and a residual network are used as prediction models to predict waviness.Conclusions The results indicate that, under the same number of selected features, the proposed multi-sensor process variable selection method outperforms the other four correlation-based feature selection methods (PCC, SCC, MI, MIC) in terms of predictive performance, achieving a balance between feature selection time complexity and prediction accuracy. Moreover, compared to the traditional two-dimensional (feature-time) sample construction method, the proposed three-dimensional (feature-time-procedure) sample space representation method, utilizing ResNet for temporal-spatial feature extraction and local-global feature fusion, further improves the model’s prediction accuracy. …”

    Rapid Colonisation of Synanthropic Stone Martens in a Highly Urbanised Region: Insights From Temporal and Spatial Analysis by Karen Cox, Jan Gouwy, Joachim Mergeay, Sabrina Neyrinck, Koen Van Den Berge

    Published 2025-05-01
    “…Using genotypes from 5536 SNPs across 376 stone martens collected between 1995 and 2013, our findings indicate that stone martens successfully expanded through urban environments, yet dispersal was neither entirely random nor strictly distance‐dependent. The initial southeastern stronghold (E1) showed the lowest genetic diversity and limited spatial expansion, while other population sources contributed to recolonisation, highlighting a complex, multi‐source expansion. …”
