Ruido Magnético Barkhausen y Emisión Magneto Acústica en probetas de aleación Fe-1 wt % Cu
(2009-11)
Tanto el Ruido Barkhausen (RB) como la Emisión Magneto Acústica (EMA), en materiales ferromagnéticos, dependen de las características microestructurales de los mismos y forman parte de las técnicas de caracterización no ...
Numerical model of UOE steel pipes: Forming processand structural behavior
(ASOCIACIÓN ARGENTINA DE MECÁNICA COMPUTACIONAL AMCA, 2007)
Deepwater pipelines are designed to withstand, without collapsing, the external pressureand bending imposed on them, either by the laying process or by the topology of the sea bottom. In
previous publications CINI researchers ...
Molecular rotational diusion detected by dierential fluorescence energy
(2000-03-01)
In this paper, we present a complete study of the influence of the molecular rotational diffusion movement in the fluorescence signal when a sample is excited by two short pulses. The study includes the calculations of ...

Simultaneous measurement of deformation and thickness change in polymer films
(2006-08-14)
We present experimental results in deformation measurement and thickness change in polymer films employing Fourier domain interferometry. The set-up is a Michelson configuration in which interference signal betweeen light ...
Simple method for thickness measurement in opaque samples with a Michelson-Sagnac interferometer
(2008-04-24)
We present in this work a method to measure thicknesses of opaque samples. The technique combines the use of low coherence interferometry with a Michelson-Sagnac configuration. This ring set-up let us to measure both faces ...
