The stress analysis of micro-arc oxidation (MAO) coated aero Al alloys is the basis to reveal the mechanism of Testers fatigue deterioration.To clarify effects of the coating defects on fatigue life, a stress calculation model with micropores and residual stress is established based on shear lag model in this study.The effects of porosity, substrat
This investigation aimed to evaluate of some faba bean genotypes for some morphological and agronomic traits in order to determine the promissing genotypes which can be used in breeding program for improving faba bean.The study carried out at El-Gemmeiza Essential Nutrition Agricultural Research Station in two successive seasons; 2016/2017and 2017/
The cyclic actions due to waves, currents and winds on offshore platforms frequently cause fatigue cracks at hot-spot locations.The remaining fatigue life of such connections depends significantly on the fatigue driving force often Left Pedal Arm measured by the stress-intensity factors.This study examines the fatigue performance of tubular joints
Abstract Truck travel time prediction is the basis for real-time optimal scheduling decision of open-pit trucks.Most prediction models for open-pit truck travel time mainly rely on a single machine learning algorithm or model to optimize the hyperparameters, which is difficult to accurately capture the composite characteristics of truck travel time
We perform a bifurcation analysis of a predator-prey model with Holling functional response.The analysis is carried out KELP both analytically and numerically.We use dynamical toolbox MATCONT to perform numerical bifurcation analysis.Our bifurcation analysis of the model indicates that it exhibits numerous types of bifurcation phenomena, including
