Dynamic tracking with simultaneous edge enhancement
(Elsevier Gmbh, 2017-11)
Due to the isotropic edge enhancement, the vortex phase filters are of commonly used in spatial filtering. In general, these filters employ a spiral phase mask on the Fourier plane, the square modulo from this convolution ...
Improving the potential of Enhanced Teager Energy Cepstral Coefficients (ETECC) for replay attack detection
(2022-03-01)
In the scope of voice biometrics, the term replay attack, (RA) refers to the dishonest attempt made by an impostor to spoof someone else's identity by replaying the subject's previously recorded speech close to the Automatic ...
SURFACE-ENHANCED RAMAN SCATTERING: METAL NANOSTRUCTURES COATED WITH LANGMUIR-BLODGETT FILMS
(Sociedad Chilena de Química, 2010)
Harmonic demodulation and minimum enhancement factors in field-enhanced near-field optical microscopy
(Wiley Blackwell Publishing, Inc, 2015-01)
Field enhanced scanning optical microscopy (FESOM) relies on the design and fabrication of plasmonic probes which had to provide optical and chemical contrast at the nanoscale. In order to do so, the scattering containing ...
Surface-enhanced raman scattering: metal nanostructures coated with langmuir-blodgett films
(Soc Chilena Quimica, 2010-12-01)
This review deals with surface-enhancved Raman scattering (SERS) employing Langmuir-Blodgett (LB) films, which serve as model systems for developing theoretical and experimental studies to elucidate the SERS effect. In ...
Enhancing a requirements baseline with scenarios
(Universidad de Belgrano - Facultad de Ingeniería y Tecnología Informática - Proyectos de Investigación, 1997)
Scenarios are well recognised as an important strategy towards understanding the interface between the environment and the system as well as a means of eliciting and specifying software behaviour. We adopt a broader view ...

This review deals with surface-enhancved Raman scattering (SERS) employing Langmuir-Blodgett (LB) films, which serve as model systems for developing theoretical and experimental studies to elucidate the SERS effect. In ...
Separate K-line contributions to fluorescence enhancement in electron probe microanalysis
(Elsevier Science, 2013-01)
The behaviour of the fluorescence enhancement correction factor in electron probe microanalysis, as a function of incident electron energy and take-off angle, is assessed for different binary samples in a wide range of ...
Enhanced transmission via evanescent-to-propagating conversion in metallic nanoslits: role of Rayleigh anomalies
(IOP Publishing, 2014-03)
We analyze the enhanced transmission phenomenon in subwavelength slit structures near a dielectric interface. In particular, we investigate the influence of Rayleigh anomalies in the spectral position as well as in the ...
