New Possibilities and Applications of the Least Squares Collocation Method
Least squares collocation method (LSC) is a versatile numerical method for solving boundary value problems for PDE. The present article demonstrates the abilities of LSC to solve various problems – in particular, calculations of bending of isotropic ...

Least-Squares Collocation With Integer Parameters [PDF]
The prediction of spatially and/or temporal varying variates based on observations of these variates at some locations in space and/or instances in time, is an important topic in the various spatial and Earth sciences disciplines. This topic has been extensively studied, albeit under different names.

On the uncertainty of height anomaly differences predicted by least-squares collocation
A network of pointwise available height anomalies, derived from levelling and GPS observations, can be densified by adjusting a gravimetric quasigeoid using least-squares collocation.

Volterra Black-Box Models Identification Methods: Direct Collocation vs. Least Squares
The Volterra integral-functional series is the classic approach for nonlinear black box dynamical system modeling. It is widely employed in many domains including radiophysics, aerodynamics, electronic and electrical engineering and many others ...

Modeling of Inhomogeneous Spatio-Temporal Signals by Least Squares Collocation
AbstractThrough inverse modeling and adjustment techniques, the geodesists try to derive mathematical models from their measurements to get a better understanding of various processes in the system Earth. Sophisticated deterministic and stochastic models are developed to achieve the best possible reflection of reality and the remaining uncertainty.The ...

Generalized method of least squares collocation [PDF]
summary:Two general solutions of the collocation problem of physical geodesy are given. Their mutual equivalency and equivalency of them to the classical solution in the regular case are proved.

A High-Resolution Gravimetric Geoid Model for Kuwait Using the Least-Squares Collocation
A new gravimetric geoid model, the KW-FLGM2021, is developed for Kuwait in this study. This new geoid model is driven by a combination of the XGM2019e-combined global geopotential model (GGM), terrestrial gravity, and the SRTM 3 global digital elevation ...
