AISI 4340 and AISI 4140 are normally used for different structural applications in quenched and tempered state due to their high strength, high abrasion and fatigue resistance but they lack toughness.Presence of dual phase microstructure such as ferrite-bainite and ferrite-martensite in steels have been reported to improve toughness but at the cost
Spatio-Temporal Variability of Anthropogenic and Natural Wrack Accumulations along the Driftline: Marine Litter Overcomes Wrack in the Northern Sandy Beaches of Portugal
Marine litter can end up deposited on sandy beaches and become entangled in the natural wrack, threatening its roles in ecosystems.However, it is currently unknown whether the storage of both artificial and natural accumulations on sandy beaches is correlated.Here, we quantified and compared, by first time, the litter and natural wrack on five sand
Optimization of laser sharpening parameters for diamond grinding wheel based on CNN
To optimize laser sharpening parameters for bronze diamond grinding wheels, the laser sharpening test was VITAMIN B12 CYANOCOBALAMIN 1000MCG carried out on the bronze diamond grinding wheel using the orthogonal test method.The convolutional neural network (CNN) is used to identify the diamond abrasive grains at the pixel level.The protruding height
Radiation Efficiency Enhancement of Graphene Plasmonic Devices Using Matching Circuits
In the present work, the radiation properties of a graphene plasmonic patch antenna are investigated and enhanced in terms of efficiency, utilizing circuit-matching techniques.Initially, the reflection coefficient of graphene surface waves due to discontinuities is studied, while the power flow towards free-space is numerically extracted.This analy
