    Responses of grassland soil mesofauna to induced climate change by Iwona Gruss, Marta Czarniecka-Wiera, Sebastian Świerszcz, Magdalena Szymura, Tomasz Szymura, Małgorzata W. Raduła

    Published 2025-05-01
    “…Redundancy analysis (RDA) revealed that plant traits explained 37.91% of the variation in mesofauna structure. Structural Equation Modelling (SEM) further supported these findings, showing that climate exerted a strong negative effect on soil quality, which in turn had a pronounced positive influence on plant quality (total effect = 0.678). …”

    Application of Prior-knowledge for Intelligent Gear Fault Diagnosis Under Variable Speed Condition by Pan Can, Li Weihua

    Published 2018-01-01
    “…The vibration mechanism analysis of gear transmission system shows that,the vibration response signal of a gear transmission system contains interference components that vary greatly with the speed and cannot reflect the fault information,the fault characteristics in amplitude spectrum of the vibration response signal have less sensitivity to the variation of running speed. These interference components can be removed with the help of prior-knowledge which is composed of structure parameters,operating parameters and the vibration mechanism of gear transmission system. …”
