Chirp-wave expansion of the electron wavefunctions in atoms
(2014)
The description of the electron wavefunctions in atoms is generalized to the fractional Fourier series. This method introduces a continuous and infinite number of chirp basis sets with linear variation of the frequency to ...
A particle swarm optimization approach to log-gabor filtering in fourier transform profilometry
(OSA - The Optical Society, 2018)
In this work, we propose a particle Swarm Optimization approach to Log-Gabor filtering in Fourier transform profilometry. Encouraging experimental results show the advantage of the proposed method. © 2018 The Author(s)
Standard passivity-based control for multi-hydro-turbine governing systems with surge tank
(Elsevier Inc., 2020)
This paper addresses the problem of control design for hydro-turbine governing systems with surge tanks from the perspective of standard passivity-based control. The dynamic model of a synchronous machine is considered in ...
Design and implementation of a balanced scorecard in a colombian company
(Revista Espacios, 2017)
This article presents the design and implementation of a Balanced Scorecard (BSC) in a medium-sized company in Colombia, providing synthetic indicators for objectives, perspectives and business strategies through key ...
The notion of Kierkegaardian conscience as an implication of the outside world: A critique of the Cartesian approach
(Universidad del Norte, 2019)
This article aims at showing how the Danish philosopher SØren Kierkegaard, through his concept of conscience, criticizes Cartesian skepticism upon affirming the impossibility of doubting the outside world, since the very ...
A convex OPF approximation for selecting the best candidate nodes for optimal location of power sources on DC resistive networks
(Elsevier B.V., 2019)
This paper proposes a convex approximation approach for solving the optimal power flow (OPF) problem in direct current (DC) networks with constant power loads by using a sequential quadratic programming approach. A ...
The maximal subspace for generation of (a,k)-regularized families
(2012)
Let A be a linear operator in a Banach space X. We define a subspace of X and a norm such that the part of A in such subspace generates an (a, k)-regularized resolvent family. This space is maximal-unique in a suitable ...
Element Free Galerkin (EFG) sensitivity study in structural analysis
(Institute of Physics Publishing, 2019)
The present study shows a parametric analysis of the meshfree method, Element Free Galerkin (EFG), on the elastic analysis of a cantilever beam. This study allows us to determine the best convergence conditions of the ...
Umbilical cord and preeclampsia
(IOS Press, 2016)
Preeclampsia is associated with abnormalities in the umbilical cord in several ways: morphological, biochemical and functional. Alteration in blood vessels of the placenta, decidua and circulatory system of the fetus might ...
A machine learning model for occupancy rates and demand forecasting in the hospitality industry
(Springer Verlag, 2016)
Occupancy rate forecasting is a very important step in the decision-making process of hotel planners and managers. Popular strategies as Revenue Management feature forecasting as a vital activity for dynamic pricing, and ...
