Modifying the stochastic model to mitigate GPS systematic errors in relative positioning
(2007-12-01)
The GPS observables are subject to several errors. Among them, the systematic ones have great impact, because they degrade the accuracy of the accomplished positioning. These errors are those related, mainly, to GPS ...
Identification of transmission line parameters from temporal measurements of currents and voltages in their terminals: Influence oh the length line
(2012-12-11)
The objective of this paper is to show a methodology to estimate transmission line parameters. The method is applied in a single-phase transmission line using the method of least squares. In this method the longitudinal ...

Weighted Generalized Inverses, Oblique Projections, and Least-Squares Problems
(Taylor & Francis, 2005-09)
A generalization with singular weights of Moore–Penrose generalized inverses of closed range operators in Hilbert spaces is studied using the notion of compatibility of subspaces and positive operators.

General two-dimensional least-squares image subtraction
(2010)
A very general two-dimensional solution to the image convolution problem is presented extending the least-squares approach of Bramich. Image convolution is of wide applicability in astronomical data reduction including, ...
