Large-scale inverse problems arise in a variety of significant applications in image processing, and efficient regularization methods are needed to compute meaningful solutions. This chapter surveys three common mathematical models including a linear, a separable nonlinear, and a general nonlinear model. ...
Different from the past negative views of elastomer covers for their filtering effect on mechanical signals, this work utilizes its signal diffusion effect to make mechanical stimulus detectable by a sparse sensor array. As a continuous layer, the stress distribution inside the elastomer layer has a...
