In this paper, a New Signature Steganography Document Image system based on Beta Elliptic Display prom Modeling is proposed, in the purpose of hiding the Beta Elliptic signature as a secret data into the host document image.The system is sub-divided into two main blocks: steganography embedding and steganography extraction.The Binary Robust Invaria
This paper presents a nonlinear cascaded control design that has been developed to (1) improve the self-sensing speed control performance of an interior permanent magnet synchronous motor (IPMSM) drive by reducing its speed and torque ripples and its phase current harmonic distortion and (2) attain the maximum torque while utilizing the minimum dri
Aiming at the problem of deformation and destruction of the overlying roadway of overhead-mining in very File Cabinet thin seam, the research methods of measuring the roadway loosening circle and 3D laser scanner to monitor the deformation of the roadway using geological radar are studied.The monitoring results show that the severe deformation of t
