It is known that certain structures of the signal in addition to the standard notion of sparsity (called structured sparsity) can improve the sample complexity in several compressive sensing applications. Recently, Hegde et al. [17] proposed a framework, called approximation-tolerant model-based compressive sensing, for recovering signals with structured(More)
The uniformity of polymer melt flow in micro extrusion die determines the quality of products directly. It is the base of extrusion die design. According to rheology testing theory and with the help of capillary rheometer, the reasonable extrusion parameters have been achieved. The comparative micro scale viscosity model is built based on Kelvin-Voigt(More)
