Analysis of the behavior of daily maximum rainfall within the department of Atlántico, Colombia
(MDPI AG, 2019)
In the Colombian Caribbean region, there are few studies that evaluated the behavior of one of the most commonly used variables in hydrological analyses: the maximum daily rainfall (Pmax-24h). In this study, multiannual ...
Early characteristics and predictors of clinical severity in Autism Spectrum Disorder
(Universidad CES, 2019)
Significant efforts have been made to detect Autistic Spectrum Disorder (ASD) during the first years of life, with positive effects on the prognosis of children. However, in countries such as Colombia early identification ...
An exact MINLP model for optimal location and sizing of DGs in distribution networks: A general algebraic modeling system approach
(Ain Shams University, 2019)
This paper addresses the classical problem of optimal location and sizing of distributed generators (DGs) in radial distribution networks by presenting a mixed-integer nonlinear programming (MINLP) model. To solve such ...
Economic Dispatch of BESS and renewable generators in DC microgrids using voltage-dependent load models
(MDPI AG, 2019)
This paper addresses the optimal dispatch problem for battery energy storage systems (BESSs) in direct current (DC) mode for an operational period of 24 h. The problem is represented by a nonlinear programming (NLP) model ...
Effect of a commercial air valve on the rapid filling of a single pipeline: A numerical and experimental analysis
(MDPI AG, 2019)
The filling process in water pipelines produces pressure surges caused by the compression of air pockets. In this sense, air valves should be appropriately designed to expel sufficient air to avoid pipeline failure. Recent ...
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, ...
Energy consumption feedback devices' impact evaluation on domestic energy use
(Elsevier Ltd, 2013)
Household energy accounts for one of the major contributors to the countries energy balances. It has been shown, that an effective way to achieve energy saving in that sector, is by providing consumers with information and ...
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 ...
Optimal Power Flow on DC Microgrids: A Quadratic Convex Approximation
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief shows a convex quadratic approximation for the optimal power flow (OPF) in direct-current microgrids (dc-μ Grid) via Taylor's series expansion. This approach can be used for solving OPF problems on radial ...
