3D Reconstruction of Surface Topography using Ultrasonic Transducer
free download
Image reconstruction can be termed as the first stage of Computer Vision. The task of regenerating a 3D or a 2D image from a given target object involves the use of sensors. The type of sensor to use are design and requirement respective, since different type of sensors This paper develops an adaptive backstepping optimal control scheme for a fractional-order chaotic magnetic-field electromechanical transducer with the saturated control inputs. A dynamical analysis is used to check for abundant dynamical behaviors of the system by

LncRNA IGFBP4-1 promotes tumor development by activating Janus kinase-signal transducer and activator of transcription pathway in bladder urothelial
free download
Insulin-like growth factor binding protein 4 1 (IGFBP4 1), a new long noncoding RNA (lncRNA), has been reported to contribute to tumorigenesis and has been suggested to be a poor prognostic marker in human lung cancer. However, there still lacks basic studies thatAlthough finite state transducers are very natural and simple devices, surprisingly little is known about the transducibility relation they induce on streams (infinite words). We collect some intriguing problems that have been unsolved since several years. The transducibility
