DOI: 10.1002/mrm.29419
Abstract: In an MRI system, the static magnetic field homogeneity is strictly required especially in ultrahigh field situations. However, owing to the engineering tolerances and system errors, the magnetic field homogeneity of a magnet usually cannot… read more here.

DOI: 10.11591/ijeecs.v13.i1.pp147-154
Abstract: Sharp development progress of information technology has affected many aspects including data security. This is because classified data are often transferred between systems. In this case, data hiding exists to protect such data. Some methods… read more here.
