Influence of vehicular traffic on environmental noise spectrum in the tourist route of Santa Marta City
(Elsevier Ltd, 2019)
Transportation demands large amounts of fuel. In particular, road transport greatly contributes to both criteria air pollutants and noise within cities. The influence of vehicular traffic on the environmental noise spectrum ...
A three layer supply chain model with multiple suppliers, manufacturers and retailers for multiple items
(2014)
The replenishment size/production lot size problem both for perfect and imperfect quality products studied in this paper is motivated by the optimal strategy in a three layer supply chain consisting of multiple suppliers, ...
Change and variability: A framework in studies on the first year of life
(Universidad Catolica de Colombia, 2013)
This article presents empirical evidence of variability and change in the performance of young children in causality tasks, highlighting the relevance of nonlinear perspective in studies about the first year of life. Using ...
Conformastatic disk-haloes in Einstein-Maxwell gravity
(2013)
We present a relativistic model describing a thin disk surrounded by a halo in the presence of an electromagnetic field. The model is obtained by solving the Einstein-Maxwell equations on a particular conformastatic spacetime ...
Fractional Fourier analysis of random signals and the notion of α -Stationarity of the Wigner-Ville distribution
(2013)
In this paper, a generalized notion of wide-sense α-stationarity for random signals is presented. The notion of stationarity is fundamental in the Fourier analysis of random signals. For this purpose, a definition of the ...
International technology adoption, R&D, and productivity growth
(Walter de Gruyter GmbH, 2013)
International knowledge diffusion is considered an important source of productivity growth. However, direct observations on such diffusion have not been available at the macro level. We analyze novel data on international ...

Economic dispatch of energy storage systems in dc microgrids employing a semidefinite programming model
(Elsevier Ltd, 2019)
A mathematical optimization approach for the optimal operation focused on the economic dispatch for dc microgrid with high penetration of distributed generators and energy storage systems (ESS) via semidefinite programming ...
Trends and Perspectives of Sustainable Product Design for Open Architecture Products: Facing the Circular Economy Model
(Korean Society for Precision Engineering, 2019)
The purpose of this paper is to perform the analysis of literature review regarding the design of open architecture products (OAP) and their potential benefits within the circular economy (CE) model. The analysis involved ...
LRemoving Dust Artifacts in Retinal Images via Dictionary Learning and Sparse-Based Inpainting
(Institute of Electrical and Electronics Engineers Inc., 2019)
In the field of ophthalmology, retinal images are essential for the diagnosis of many diseases. These images are acquired with a device called the retinal camera. However, often small dust particles in the sensor produce ...
