Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Evaluation of the Sex and Species Distribution, Breeding, and Life Expectancy of Zoo‐Housed Chameleons

Zoo Biology, EarlyView.
ABSTRACT More than a third of the 202 identified chameleon species are classified as “vulnerable” or “critically endangered”. No data is available regarding the life expectancy of chameleons kept in zoos. The objectives of this study were to determine the sex and species distribution of chameleons kept in zoological institutions, and to assess their ...

Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Exploring clean energy alternatives to fossil fuels has become a major research focus worldwide. Wind energy is regarded as one of the most promising renewable energy sources due to its clean and sustainable nature. However, wake interactions among turbines significantly reduce power conversion efficiency, making wind farm layout optimization (

Energy Flows Balance of Electric‐Heating Interconnected Microgrids Under Grid‐Forming Converter Integration Based on Heterogeneous Graph Convolutional Network

Energy Internet, EarlyView.
ABSTRACT The combination of electric‐heating interconnected microgrids (EHIMs) with grid‐forming converters (GFMCs) offers a highly promising approach to improving energy management within decentralised energy systems. Despite its potential, precisely modelling and analysing energy flow in such systems remains a considerable challenge due to the ...
