Inclination shift signal: thickness or index measurement in transparent media by transmission of generally astigmatic Gaussian beams
(Elsevier, 2021-04)
The focus error signal is a widespread optical technique that harnesses the shape of a simply astigmatic Gaussian beam to produce an output signal with a well-defined linear range used for many different applications. ...
Slope estimation influences on ice thickness inversion models: A case study for Monte Tronador glaciers, North Patagonian Andes
(Cambridge University Press, 2020-08)
Glacier ice thickness is crucial to quantifying water resources in mountain regions, and is an essential input for ice-flow models. Using a surface velocity inversion method, we combine ice thickness measurements with ...
Equations of bark thickness and volume profiles at different heights with easy-measurement variables
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2012)
The objective of this work was to develop equations of thickness profile and bark volume at different heights with easy-measurement variables, taking as a study case Nothofagus pumilio forests, growing in different site ...
Métodos de medición de espesores de películas delgadas basadas en óxidos semiconductores
(Sociedad Mexicana de Física, 2018-08)
Las películas transparentes basadas en éxidos de Ti, Sn y Zn tienen gran importancia en dispositivos electrónicos tales como sensores, celdas solares y películas conductoras haciendo que las técnicas de caracterización ...
Semiempirical model for analysis of inhomogeneous optically thick laser-induced plasmas
(Pergamon-Elsevier Science Ltd, 2009-10)
Abstract In this paper, a more realistic approach of a non-uniform optically thick plasma in local thermodynamic equilibrium was applied to describe self-reversal of Co I 340.51 nm emission line recorded from a laser-induced ...
Capacitance and resistance measurements of SnO2 thick-films
(Springer, 2008-02-05)
Impedance spectroscopy measurements on SnO2 thick films were carried out in an air atmosphere and for temperatures between 25 0C and 425 0C. Capacitance and resistance analyses reveal the mechanisms responsible for ...
Ionic environment, thickness and line tension as determinants of phase separation in whole Purified Myelin Membranes monolayers
(Elsevier Science, 2021-11)
Purified myelin membranes (PMM) were spread as monomolecular films at the air/aqueous solution interface, and visualized by Brewster Angle Microscopy (BAM) at different lateral pressures (π) on three specific aqueous ...
Variation in reproductive frost susceptibility of wheat cultivars is not associated with variation in glume and lemma thickness
(Elsevier, 2020-11-05)
The thickness of wheat (Triticum aestivum L.) glumes and lemmas (TGL) influences their thermal insulation properties, which in turn, may influence reproductive frost susceptibility. The objectives of this study were to (i) ...
Metastable effects on martensitic transformation in SMAs: Part X. An approach to thermodynamic changes induced for the S-shaped cycles in thick wires of NiTi
(Springer, 2017-04-01)
The transformation and retransformation paths realized at constant stress in wires of NiTi SMAs show a horizontal or “flat” behavior in the hysteretic cycle. After sinusoidal cycling at 0.01 Hz (i.e., training) with a ...
