Scattered Data Interpolation Using Rational Quartic Triangular Patches With Three Parameters
IEEE Access, 2020 This paper discusses the construction of scattered data interpolation scheme based on rational quartic triangular patches with C1 continuity. The C1 sufficient condition is derived on each adjacent triangle. We employ rational corrected scheme comprising

An Efficient Density-Based Local Outlier Detection Approach for Scattered Data
IEEE Access, 2019 After the local outlier factor was first proposed, there is a large family of local outlier detection approaches derived from it. Since the existing approaches only focus on the extent of overall separation between an object and its neighbors, and ignore

Progressive scattered data filtering
Journal of Computational and Applied Mathematics, 2003 The author discusses the construction of a sequence of subsets of decreasing sizes such that their converting radii are small. A method for progressive data reduction, called ``scattered data filtering'', is proposed and analyzed.

An analytical model for turbulence scattered rays in the shadow zone for outdoor sound propagation calculation [PDF]
, 2009 In outdoor sound propagation, an inherent problem of the ray tracing method is its inability to determine the sound pressure level in the shadow zone, where geometrical rays do not penetrate.

A near-surface seismic scattered wave separation method
Petroleum Exploration and Development, 2014 Considering that near-surface scattered waves could not be suppressed by conventional denoise method, this paper analyzes the characteristics of scattered waves and achieves the near-surface scattered wave separation by the seismic interferometry theory.

Construction of Cubic Timmer Triangular Patches and its Application in Scattered Data Interpolation
Mathematics, 2020 This paper discusses scattered data interpolation by using cubic Timmer triangular patches. In order to achieve C1 continuity everywhere, we impose a rational corrected scheme that results from convex combination between three local schemes.
