In particular, we can obtain much ...
First, a sparse representation model based on the L 1/2 -norm penalty is developed to identify blade vibration frequency and blade-tip displacement. Second, a displacement-to-strain transmissibility (DST) is proposed for strain reconstruction from identified displacement. The mode shapes of the ...

In the stage of image reconstruction,because of the problems that the solution based on L1 regular model is usually not sparse enough and the quality of the reconstructed image needs to be further improved,L1/2 norm is employed to substitute L1 norm to establish the super resolution ...
