Sliding mode reference coordination of constrained feedback systems
(Hindawi Publishing Corporation, 2013-12)
This paper addresses the problem of coordinating dynamical systems with possibly different dynamics (e.g., linear and nonlinear, different orders, constraints, etc.) to achieve some desired collective behavior under the ...
Improving the relationship between reference frames by using the Thin-Plate Spline modelling
(2012-01-01)
The adoption of new geodetic reference systems and/or the availability of new reference frames occur, mainly, by the availability of new data sets. For the use of products in different reference frames, methods are necessary ...
Riemann normal coordinates, Fermi reference system and the geodesic deviation equation
(1999)
We obtain the integral formulae for computing the tetrads and metric components in Riemann normal coordinates and the Fermi coordinate system of an observer in arbitrary motion. Our approach admits an essential enlarging ...

Transformação de coordenadas com modelagem de distorções entre SAD69 e SIRGAS2000 com o uso de Thin-Plate Splines
(Univ Federal Parana, Centro Politecnico, 2014-01-01)
Several countries have been passed by change processes in their fundamental geodesic structure with the focus on the adoption of geocentric reference systems. In Brazil, the adoption of the SIRGAS2000 evolves the coexistence ...
Indirect georeferencing of terrestrial laser scanning data using control lines
(2013-09-01)
An indirect method for the georeferencing of 3D point clouds obtained with terrestrial laser scanning (TLS) data using control lines is presented. This technique could be used for rapid data acquisition where resources do ...
