Wiebke Helm,Sebastian Schmideleracting the vibration information that can reflect the different operation states of elevator, the signal is preprocessed by the multi-threshold denoising method of wavelet packet, and the predicted data is extracted by feature information. The vibration acceleration signals of elevator in X, Y and Z

Christiane Fritze,Monika Kiegler-Griensteidl the performances of misaligned hydrodynamic journal bearing. The geometric model of a misaligned bearing is established. Quadratic programming is used to study the influence of wall slip on the hydrodynamic lubrication performance of a two-dimensional journal bearing. The numerical simulation metho

https://doi.org/10.1007/978-3-540-79743-2re. Using the HFSS microwave simulation software, a half-wave dipole feed structure was first designed, and a slotted dielectric Fresnel lens antenna was designed based on the half-wave dipole feed structure. Then, through simulation and comparison of the effect of different full-wave periods w on t
