Generational diversity and quality of work life: Case study in the Colombian logistic sector
(International Business Information Management Association, IBIMA, 2019)
Drawing upon generational differences in work values and attitudes, this article examines perception of quality of work life of three generational cohorts using survey data collected from 522 employees of the logistic ...
Robust detection and removal of dust artifacts in retinal images via dictionary learning and sparse-based inpainting
(SPIE, 2019)
Retinal images are acquired with eye fundus cameras which, like any other camera, can suffer from dust particles attached to the sensor and lens. These particles impede light from reaching the sensor, and therefore they ...
A Hooke's law-based approach to protein folding rate
(Academic Press, 2015)
Kinetics is a key aspect of the renowned protein folding problem. Here, we propose a comprehensive approach to folding kinetics where a polypeptide chain is assumed to behave as an elastic material described by the ...
Relational Agreement Measures for Similarity Searching of Cheminformatic Data Sets
(Institute of Electrical and Electronics Engineers Inc., 2016)
Research on similarity searching of cheminformatic data sets has been focused on similarity measures using fingerprints. However, nominal scales are the least informative of all metric scales, increasing the tied similarity ...
Fractional sampling theorem for -bandlimited random signals and its relation to the von neumann ergodic theorem
(Institute of Electrical and Electronics Engineers Inc., 2014)
Considering that fractional correlation function and the fractional power spectral density, for -stationary random signals, form a fractional Fourier transform pair. We present an interpolation formula to estimate a random ...
A density functional theory study of the reconstruction of gold (111) surfaces
(American Chemical Society, 2014)
We studied (p × √3) gold (111) surface reconstructions within the DFT/PW91 approximation. Our findings clearly show that the reconstruction is energetically favorable in unreconstructed surfaces equal to or larger than the ...
Noise-Robust Processing of Phase Dislocations using Combined Unwrapping and Sparse Inpainting with Dictionary Learning
(Institute of Electrical and Electronics Engineers Inc., 2019)
The problem of phase unwrapping from a noisy and also incomplete wrapped phase map arises in many optics and image processing applications. In this work, we propose a noise-robust approach for processing regional phase ...
Numerical Approximation of the Maximum Power Consumption in DC-MGs with CPLs via an SDP Model
(Institute of Electrical and Electronics Engineers Inc., 2019)
This brief addresses the numerical approximation of the maximum power consumption in direct-current microgrids (DC-MGs) with constant power loads through a convex optimizing model. The convex formulation is developed via ...
Sequential quadratic programming models for solving the OPF problem in DC grids
(Elsevier Ltd, 2019)
In this paper, we address the optimal power flow problem in dc grids (OPF-DC). Our approach is based on sequential quadratic programming which solves the problem associated with non-convexity of the model. We propose two ...
A vision-based system for the dynamic measurement of in-plane displacements
(Institute of Electrical and Electronics Engineers Inc., 2014)
Computer vision has advanced markedly in the last decade and has had new applications such as the analysis of the behavior of structures. The analysis of displacement and deformation of structures is an important process ...
