The paper presents a theory of body collision with pit corner.The theory can be successfully applied in approaching tasks coping with the orientation of details in technological processes and control systems, the motion of elements natio celebrate eyeshadow palette in mechanisms having a gap, collisions in motion of different sport objects, the ana
The tail gear reducer is an important component of the helicopter transmission system, and bearing preloading is a key link in the assembly of the tail gear reducer, which directly affects the stability, service life, and noise of the helicopter tail rotor.According to the bearing support configuration, a force model of the preloaded bolt is establ
A water quality parameter retrieval scheme based on the UAV push-broom hyperspectral images was designed and validated for assessing the ecological health of Zhang read more Wei Xin River in Dezhou distinct, China.First, a UAV carrying a push-broom hyperspectral imager that is lightweight and has a small size was used to acquire high spatial and hy
The thermal characteristics of modified hybrid nanoparticles have been studied between two parallel walls with applications of entropy generation and nonlinear thermal radiation.Three types of nanoparticles namely copper oxide (CuO), copper nanoparticles (Cu) and aluminum oxide (Al2O3) are utilized to thermal determination of heat transfer.The cont
Many viruses occur in apple (Malus domestica (Borkh.)), but no information is available on their seed transmissibility.Here, we report that six viruses infecting apple trees, namely, apple chlorotic leaf spot virus (ACLSV), apple green crinkle-associated virus sensationnel kiyari (AGCaV), apple rubbery wood virus 2 (ARWV2), apple stem grooving viru
