Prediction of concrete life under coupled dry and wet-sulfate erosion based on damage evolution equation [PDF]
Archives of Civil Engineering, 2023 In a corrosive environment with coupled dry-wet-sulfate action, concrete structures are susceptible to erosion by sulfate ions, which seriously affects the safe operating life.

The interplay of domain-and life satisfaction in predicting life events [PDF]
PLOS ONE, 2020 To better understand the occurrence of major changes in people´s lives like job changes or relocations, we test a model of motivational consequences of life and domain satisfaction using data of the German socio-economic panel study (SOEP) (waves 2005-2015; Ns between 2,201 and 28,720).

Probabilistic fatigue life prediction of metallic components based on continuum damage mechanics
Xibei Gongye Daxue Xuebao, 2021 Based on continuum damage mechanics, a probabilistic method of predicting high-cycle fatigue life for metallic components is proposed. First, macro-meso two-scale stress-strain equations are established by combining Eshelby-Kroner localization law and ...

Entropy and the Predictability of Online Life [PDF]
Entropy, 2014 Using mobile phone records and information theory measures, our daily lives have been recently shown to follow strict statistical regularities, and our movement patterns are, to a large extent, predictable. Here, we apply entropy and predictability measures to two datasets of the behavioral actions and the mobility of a large number of players in the ...

Prediction of the human life expectancy [PDF]
Theory in Biosciences, 2003 We have simulated demographic changes in the human population using the Penna microscopic model, based on the simple Monte Carlo method. The results of simulations have shown that during a few generations changes in the genetic pool of a population are negligible, while improving the methods of compensation of genetic defects or genetically determined ...

Proposed Design Against High-Cycle Fatigue Failure of Metallic Beams Using Lamination [PDF]
Engineering and Technology Journal, 2018 Fatigue analysis helps in predicting life of the component and seeks improvements of the whole process in design phase. Efforts are continually made to combat the fatigue phenomenon, yet certain mechanical components are still failing due to fatigue. The

Damage Distribution Map Based Damage Accumulation Calculation Approach for Welded Joints
Metals, 2023 Fatigue damage accumulation under variable amplitude loadings is vital for the life prediction of welded structures. An approach based on damage distribution mapping is presented. S-N curves of welded joints are utilized to construct fatigue damage zones,
