Abstract: Phase unwrapping (PU) is a key step in interferometric synthetic aperture radar (InSAR) surface monitoring, which is directly related to the accuracy of the line-of-sight (LOS) displacement observations. Underground coal mining generally results in large… read more here.

Abstract: We consider the problem of Subbotin’s parabolic spline interpolation for functions with large gradient domains. In the case of the common piecewise uniform Shishkin’s mesh we obtain two-sided accuracy estimates for the class of functions… read more here.

DOI: 10.3390/app10176110
Abstract: We present an effective method for the topography characterization of large gradient micro-structure based on digital holographic microscope (DHM). Due to the limitation of numerical aperture of DHM system, high frequency information corresponding to large… read more here.
