The geometric structures, electronic and magnetic properties of Mn-doped ZnO nanowires were investigated using density functional theory. The results indicated that all the calculated energy differences were negative, and the energy of the ground state was 0.229 eV lower than ferromagnetic coupling, which show higher stability in antiferromagnetic coupling.(More)
An image inpainting algorithm based on fractal and image decomposition is proposed in this paper. The image is decomposition into two element structure and texture, which are processed respectively according to their characteristic, structure element is inpainted by CDD (Curvature-Drive Diffusions) algorithm. And texture element is filled by fractal(More)
