Assessment of local covariance estimation through Least Squares Collocation over Iran [PDF]
Covariance determination as the heart of Least Squares Collocation gravity field modeling is based on fitting an analytical covariance to the empirical covariance, which is stemmed from gravimetric data.

A recovered Moho model by integrated inversion of gravity and seismic depths in Iran
This research aims to define the depth of Moho in Iran by collocation method using gravimetric data with seismic information. The definition of the Moho in the Iranian region is of considerable importance due to the geological complexity of the area also

A collocation method for two-point boundary value problems [PDF]
This article is concerned with the use of collocation by splines to numerically solve two-point boundary value problems. The problem is analyzed in terms of cubic splines first and then extended to the use of quintic and septic splines. Consideration is given both to convergences as the mesh is refined and to the bandwidth of the matrices involved ...

Adaptive Wavelet Collocation Method for Simulation of Time Dependent Maxwell's Equations [PDF]
This paper investigates an adaptive wavelet collocation time domain method for the numerical solution of Maxwell's equations. In this method a computational grid is dynamically adapted at each time step by using the wavelet decomposition of the field at ...
