This scientific article presents an analysis of the existing documentation obtained in Scopus (2012-2020) about the religious coping strategies possessed by university students and their usefulness. The study has as objective ...
Pseudo asymptotic solutions of fractional order semilinear equations
(2013)
Using a generalization of the semigroup theory of linear operators, we prove existence and uniqueness of mild solutions for the semilinear fractional order differential equation [mathematical equation] with the property ...
Six Sigma method to assess the quality of the service in a gas utility company
(2022-03-14)
A method to evaluate the quality of service of a customer service centre is proposed based on Six Sigma, and through an empirical and rational approach that allowed an objective perspective during the development of 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 ...
Evaluation of ultrasound by direct contact on convective drying of banana (Musa paradisiaca) slices using Principal Component Analysis and Response Surface Methodology
(2019)
Conventional convective drying is one of the latest techniques used to reduce the amount of water in foods, however, due to the long times of exposure to high temperatures, these techniques can reduce the sensory quality, ...
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 ...
