Numerical Simulation of KBKZ Integral Constitutive Equations in Hierarchical Grids
Applied Sciences, 2021 In this work, we present the implementation and verification of HiGTree-HiGFlow solver (see for numerical simulation of the KBKZ integral constitutive equation. The numerical method proposed herein is a finite difference technique using tree-based grids.

A crossvalidation-based comparison of kriging and IDW in local GNSS/levelling quasigeoid modelling
Reports on Geodesy and Geoinformatics, 2022 This study compares two interpolation methods in the problem of a local GNSS/levelling (quasi) geoid modelling. It uses raw data, no global geopotential model is involved.

Fully complex-valued radial basis function networks: orthogonal least squares regression and classification [PDF]
, 2008 We consider a fully complex-valued radial basis function (RBF) network for regression and classification applications. For regression problems, the locally regularised orthogonal least squares (LROLS) algorithm aided with the D-optimality experimental ...

A kernel-based two-class classifier for imbalanced data sets [PDF]
, 2007 Many kernel classifier construction algorithms adopt classification accuracy as performance metrics in model evaluation. Moreover, equal weighting is often applied to each data sample in parameter estimation.

Meshless Local Petrov-Galerkin Method for 3D Steady-State Heat Conduction Problems
Advances in Mechanical Engineering, 2011 The Meshless Local Petrov-Galerkin (MLPG) method is applied for solving the three-dimensional steady state heat conduction problems. This method is a truly meshless approach; also neither the nodal connectivity nor the background mesh is required for ...
