The plug-and-play framework makes it possible to integrate advanced image denoising priors into optimization algorithms efficiently solve a variety of restoration tasks generally formulated as maximum posteriori (MAP) estimation problems. alternating direction method multipliers (ADMM) and the regularization by (RED) are two examples such methods that made breakthrough in restoration. However, ...

in this research, the bending analysis of rectangular nanoplates subjected to mechanical loading is investigated. for this purpose, the strain gradient elasticity theory with one gradient parameter is presented to study the nanoplates. from the best knowledge of authors, it is the first time that the exponential shear deformation formulation based on strain gradient elasticity theory is carried...

Principles and concepts of gradient echo (GRE) imaging are the basis of many applications on modern MR-systems. The most obvious difference between Spin Echo and GRE imaging is related to the pulse sequence elements that are used to generate an MR signal (see figure 1). While two rf-pulses (90 and 180) are used for spin refocusing and spin echo generation, GRE imaging is based on only a single ...

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...
