Fractional Fourier transform method of chirped fringe pattern analysis for profilometry
(2020)
A method is proposed to obtain the 3D profile of an object or the shape of a wavefront. The analysis of linearly chirped cosenoidal fringes is performed in the fractional Fourier domain. © OSA 2020, © 2020 The Author(s)
Highway Planning Trends: A Bibliometric Analysis
(2022)
An efficient highway infrastructure network is a determining factor in promoting the socio-economic development of countries and regions. Highway planning activities are highly important because their results ensure that ...
Iron Oxide Powder as Responsible for the Generation of Industrial Polypropylene Waste and as a Co-Catalyst for the Pyrolysis of Non-Additive Resins
(2022)
For the synthesis of polymeric resins, it is of great importance to review the raw materials and the equipment to be used to avoid the presence of compounds that may affect the effectiveness of the polymerization and the ...
Influence of survey engagement and multiple-choice heuristics in the estimation of the value of a statistical life
(2023)
Estimating the value of non-market goods, such as reductions in mortality risks due to traffic accidents or air pollution, is typically done using stated choice (SC) data. However, issues with potential estimation biases ...
Adaptive control for second-order DC-DC converters: PBC approach
(2021)
This chapter deals with the design of a passivity-based controller for DC-DC converters by using a general representation for second-order converters, that is, buck, boost, buck-boost, and noninverting buck-boost converters. ...
EFFECT of the ENVIRONMENTAL CONDITIONS of TROPICAL CLIMATES on the PERFORMANCE PARAMETERS of A GAS TURBINE POWER GENERATION PLANT Fajardo J. ; Barreto D. ; Castro T. ;
(2020)
It is known that high temperatures adversely affect the performance of gas turbines, but the effect of the combination of atmospheric conditions (temperature and relative humidity -RH- ) on the operation of this type of ...
Detection of broken bars in three-phase motors by using curve fits and classification algorithms
(2022)
Since they transform electrical energy into mechanical energy, three-phase induction motors are one of the main assets that companies have. Therefore, good monitoring of their conditions and diagnosing their faults is ...
Energy Management System for the Optimal Operation of PV Generators in Distribution Systems Using the Antlion Optimizer: A Colombian Urban and Rural Case Study
(2022)
This paper presents an Energy Management System (EMS) for solving the problem regarding the optimal daily operation of Photovoltaic (PV) distributed generators in Alternate Current (AC) distribution grids. To this effect, ...
Hybrid Materials Based on Nanoparticles Functionalized with Alkylsilanes Covalently Anchored to Epoxy Matrices
(2022)
In this work, the surface modification of zinc oxide nanoparticles (ZnO-NPs) with 3-glycidyloxy-propyl-trimethoxysilane (GPTMS) was investigated. The ZnO-NPs were synthesized using the physical method of continuous arc ...
Gender differences in math and reading: Performance, self-concept and expectations
(2020)
Previous studies show gender differences in math and language performance, mainly in adolescents. In this study, we aim to evaluate gender differences in self-concept, subjective value, expectations and academic performance, ...
