The character of precipitation detected at the surface is the final product of many microphysical interactions in the cloud above, the combined effects of which may be characterized by the observed drop size distribution (DSD).This necessitates accurate retrieval of the DSD from remote sensing data, especially radar as it offers large areal coverag

Currently rail transit has no reliability qualification test standards yet.To verify whether the MTBF of Health LKJ meet the requirements, with the main working environment analysis of LKJ, comprehensive environmental conditions of six kinds of stress which consisted of temperature, humidity, vibration, shock, changes in voltage, surges and electri

This paper presents on the results of radiation studies for three commonly used wireless sensor nodes based on the following protocols: ZigBee, WirelessHART, ISA 100.11a, and network devices built with commercial off-the-shelf (COTS) components.The level of radiation considered is at par with that experienced at Fukushima Daiichi Nuclear Power Plan

Hybrid excitation motor is a combination of permanent magnet motor and electric excitation motor, which can flexibly adjust the air gap magnetic field.At present, the traditional silicon steel sheet core material is widely used, but this material limits the further reduction Car Diffuser of stator iron loss.In this paper, a new type of hybrid excit
