Late cenozoic tectonics and paleomagnetism of North Cauca Basin intrusions, Colombian Andes: Dual rotation modes
(ELSEVIER SCIENCE BV, 1996-09-15)
Further paleomagnetic results are reported from 18 sites in Late Tertiary hypabyssal igneous rocks adjacent to the Romeral fault system which forms the eastern boundary of the North Cauca Basin. The paleomagnetic directions ...
Acoustic displacement tetrahedra developed using the IET rules
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-09-01)
A four node, displacement based, acoustic element is developed. In order to avoid spurious rotational modes, a higher order stiffness is introduced. The higher order stiffness is developed from an incompatible strain field ...
Non-intrusive detection of rotating stall in pump-turbines
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTDUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2014-10-03)
When operated far from their optimum conditions, pump-turbines may exhibit strong hydrodynamic instabilities, often called rotating stall, which lead to substantial increase of vibration and risk of mechanical failure. In ...
Multiple rotation assessment through isothetic fringes in speckle photography
(OSAGrupo de Investigación de Óptica AplicadaEscuela de Ciencias y Humanidades, 2007-04-20)
The use of different pupils for storing each speckled image in speckle photography is employed to determine multiple in-plane rotations. The method consists of recording a four exposure specklegram where the rotations are ...

(OPTICAL SOC AMER, 2007-05-10)
The use of different pupils for storing each speckled image in speckle photography is employed to determine multiple in-plane rotations. The method consists of recording a four-exposure specklegram where the rotations are ...
LOCALIZATION OF SLIDING BIFURCATIONS IN A ROTATIONAL OSCILLATOR WITH DOUBLE CAM
(UNIV NAC COLOMBIA, FAC NAC MINAS, 2011-06-01)
In this work, nonsmooth and non-conventional bifurcations, also called sliding bifurcations are analyzed in a system with multiple discontinuity boundaries. The singular point tracking (SPT) method is used to locate ...

(ELSEVIER SCIENCE BV, 1996-01-01)
Paleomagnetism and magnetic fabrics of Mio-Pliocene hypabyssal rocks of the Combia event, Colombia: tectonic implications
(Akademie Ved Ceske Republiky, 2017-10-01)
Mio-Pliocene hypabyssal rocks of the Combia event in the Amaga basin (NW Andes-Colombia), contain a deformational record of the activity of the Cauca-Romeral fault system, and the interaction of terranes within the Choco ...

Acoustic displacement triangle based on the individual element test
(Universidade de Sao Paulo, 2012-01-01)
A three node -displacement based-acoustic element is developed. In order to avoid spurious rotational modes, a higher order stiffness is introduced. This higher order stiffness is developed from an incompatible strain field ...
