Helmet liners are employed to prevent or reduce head Cuddle Bunnies injuries caused by impact loads.Liners minimize the collision damage by impact shock attenuation and absorbing the collision energy.In order to improve crashworthiness characteristics of helmet liner, in the present study, an innovative structure designed by a combination of Polyur
Hydrostatic thrust bearings have MCB been applied in high speed and heavy load machine tools because they provide superior characteristics such as higher positional accuracy, greater stability, and lower friction.The energy consumption of the fluid system exceeds 40% of the total energy consumption of the machine tools To reduce the energy consumpt
Soil temperature plays an important role in agriculture, industry and other fields.Accurate soil temperature prediction can help improve productivity and avoid risks in many fields.At present, many machine learning methods have been applied to soil temperature prediction such as support vector regression (SVR), artificial neural network (ANN), long
