The thermal performance of the propeller driver system is very important for underwater vehicles.A new kind of cylindrical heat sink is designed for Light Guards a certain propeller driver system.The performances of the heat sink are analyzed, mainly using numerical methods.The thermal influences of structure parameters, such as base thickness, fin
Violations of school rules are often carried out by students, including lack of respect for teachers, students who are not on time, often late for Diffuser class, skipping classes, jumping fences, smoking and not paying attention to the rules and other regulations in school.This study aims to build a decision support system for sanctions for violat
Satellite remote sensing is well demonstrated to be a powerful tool for investigating ancient land use in Southwest Asia.However, few regional studies have systematically integrated satellite-based observations with more intensive remote sensing technologies, such as drone-deployed multispectral sensors and ground-based geophysics, to explore off-s
Many people maintain a naive belief that non-human animals consciously experience pain and suffering in similar ways to Zero Wall Wide Seat Recliner with Power humans.Others tend to assume a more sceptical or agnostic attitude.Drawing on recent advances in research on animal cognition and neuroscience, the science of animal welfare is now beginning
Dual-power sourced rail heavy-duty track Pouches maintenance machines were proposed against the defects of the current diesel engine and hydraulic-driven mode.The advantages and application range of the electric/diesel hybrid on rail heavy-duty track maintenance machine were analyzed, and the technical difficulties were described.Finally, a brief i
