Abstract: A wireless secure communication method based on RIS-NOMA under complex channel conditions, the method including: firstly, an intelligent surface is assume to be disposed between the base station and legitimate NOMA users, and between the base station and eavesdroppers; the signal to interference plus distortion noise ratio (SIDNR) for the legitimate NOMA user and the eavesdropper is calculated in the presence of RHI in the system; secondly, considering shadow fading and to simplify the overly complex calculation process, the probability density function and cumulative distribution function of the shadow fading are approximated; finally, the outrage probability and intercept probability of the legitimate users and eavesdroppers are calculated.

Abstract: Hydraulic two-side rolling-cut shears, including: a front transport roller device, a rear transport roller device, a shear body, and a roller carrier. The front transport roller device includes a laser scriber, a magnetic alignment device, and a pinch roller device. The rear transport roller device includes a vertical guide roller. The laser scriber is disposed on the front end of the front transport roller device. The magnetic alignment device is disposed in the middle part of the front transport roller device. The pinch roller device is disposed on the rear end of the front transport roller device in front of the shear body. The roller carrier is disposed longitudinally in the middle of the shear body. The vertical guide roller is disposed on the rear transport roller device and behind the shear body.
