In this paper, we propose a super-resolution (pixel grid refinement) method for digital images. It is based on the linear filtering of zero-padded discrete signal. We introduce continuous-discrete observation model to create reconstruction system. The proposed typical real-world imaging systems - an initially continuous signal first undergoes (dynamic) distortions and then subjected sampling ef...

In this paper, we present a multi-resolution smoothed particle hydrodynamics (SPH) method for modeling fluid-structure interaction (FSI) problems. By introducing different smoothing lengths and time steps, the spatial-temporal discretization is applied with resolutions fluid structure. To ensure momentum conservation at coupling, position-based Verlet integration scheme introduced. Furthermore,...

Integer ambiguity resolution is required to obtain precise coordinates for the global navigation satellite system (GNSS). Poorly observed data cause unfixed integer and reduce coordinate accuracy. Previous studies mostly used denoise filters partial algorithms address this problem. This study proposes a sequential method that includes float solution substitution process double-difference (DD) i...
