Wavelet-Based Entropy Measures to Characterize Two-Dimensional Fractional Brownian Fields
(MDPI, 2020-02-07)
The aim of this work was to extend the results of Perez et al. (Physica A (2006), 365 (2), 282–288) to the two-dimensional (2D) fractional Brownian field. In particular, we defined Shannon entropy using the wavelet spectrum ...
Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
(The Optical Society (OSA), 2013-08)
Different spatial distributions of optical vortices have been generated and characterized by implement- ing arrays of devil’s vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the ...
Dispersion management in two-photon microscopy by using diffractive optical elements
(Optical Society of America, 2013)
We demonstrate efficient generation of wide-field fluorescence signals in two-photon microscopy exploiting diffractive optical elements and short pulses by using a dispersion-compensated beam delivery optics module. ...
Revisiting the random shift approach for testing in spatial statistics
(Elsevier, 2020)
We consider the problem of non-parametric testing of independence of two components of a stationary bivariate spatial process. In particular, we revisit the random shift approach that has become the standard method for ...
CAD training for digital product quality: a formative approach with computer‑based adaptable resources for self‑assessment
(Springer, 2021-01-04)
As the engineering and manufacturing sectors transform their processes into those of a digital enterprise, future designers and engineers must be trained to guarantee the quality of
the digital models that are created and ...
Characterization of Tin/Ethylene Glycol Solar Nanofluids Synthesized by Femtosecond Laser Radiation
(John Wiley & Sons, Ltd., 2016-11-22)
Solar energy is available over wide geographical areas and its harnessing is becoming an essential tool to satisfy the ever-increasing demand for energy with minimal environmental impact. Solar nanofluids are a novel solar ...
Sketch-Based Modeling in Mechanical Engineering Design: Current Status and Opportunities
(Elsevier, 2022-05-08)
Sketch-Based Modeling (SBM) is a field of study that focuses on the automatic creation of 3D models from freehand drawings. Today, two related branches coexist: one aimed at facilitating input for 3D content creation, and ...
Femtosecond filamentation in sapphire with diffractive lenses
(Optical Society of America, 2013)
In this paper, we demonstrate novel properties in the phenomenology of supercontinuum generation in sapphire with diffractive lenses and provide a complete spatial, spectral, and temporal characterization of the so-generated ...
Metrics and barycenters for point pattern data
(Springer, 2020)
We introduce the transport–transform and the relative transport–transform metrics between finite point patterns on a generalspace, which provide a unified framework for earlier point pattern metrics, in particular the ...
Resolution analysis in computational imaging with patterned illumination and bucket detection
(Optical Society of America, 2014)
In computational imaging by pattern projection, a sequence of microstructured light patterns codified onto a programmable spatial light modulator is used to sample an object. The patterns are used as generalized measurement ...
