A New Cumulative Fatigue Damage Rule Based on Dynamic Residual S-N Curve and Material Memory Concept

open access: yesMetals, 2018
This paper introduces a new phenomenological cumulative damage rule to predict damage and fatigue life under variable amplitude loading. The rule combines a residual S-N curve approach and a material memory concept to describe the damage accumulation ...

Predicting offspring life span [PDF]

open access: yesScience, 2019
Life History Environmental and life choices affect health and reproduction. Several studies show that these effects extend to the next generation and sometimes beyond. Zipple et al. have examined a longitudinal dataset of a natural population of baboons in southern Kenya. Individuals in this group can live up to 30 years. The dataset was collected over

Specification-Driven Predictive Business Process Monitoring

open access: yes, 2019
Predictive analysis in business process monitoring aims at forecasting the future information of a running business process. The prediction is typically made based on the model extracted from historical process execution logs (event logs).

Cavitation erosion of polyethylene and chloroprene rubber for liners

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Resin lining is widely used as an anti-corrosion method for steel pipes. Since cavitation sometimes occurs near valves in piping system, it is necessary to consider not only the corrosion resistance but also the erosion resistance.

Postreproductive Life Predicted by Primate Patterns [PDF]

open access: yesThe Journals of Gerontology Series A: Biological Sciences and Medical Sciences, 2000
Regression analyses of primate life spans on recently revised female body and brain masses of Old World primates predict a human life span of between 72 years and 91 years-estimates that exceed the age of human menopause (and prior estimates) by well over 20 years.
