A proposal for an air quality monitoring system for Cartagena de Indias
(Latin American and Caribbean Consortium of Engineering Institutions, 2019)
This paper presents an Air Quality Monitoring System for the city of Cartagena de Indias. The goal of this system is to monitor the air quality in the city and to establish the current state of the air Cartagena's citizen ...
Scientific reasoning skills and patterns of use of Information and Communication Technologies. The case of the students of the Universidad de Santander (Valledupar, Colombia)
(2019-10-30)
This research establishes the relationship that has had the development of the skills of scientific reasoning and the patterns of use of tools and resources of information and communication technology (ICT). For that, it ...
Effectiveness of a visual noise warning system on noise levels in a surgical ICU: A quality improvement programme
(Lippincott Williams and Wilkins, 2019)
BACKGROUNDThe effects of noise are harmful to patients in the ICU environment, and the latter are particularly noisy places. High noise levels seem to be a factor in sleep disturbance, which can, in turn, result in increased ...
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 ...
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 ...
A submersible printed sensor based on a monopole-coupled split ring resonator for permittivity characterization
(MDPI AG, 2019)
This work presents a non-invasive, reusable and submersible permittivity sensor that uses a microwave technique for the dielectric characterization of liquid materials. The proposed device consists of a compact split ring ...
Colombian Andean thermal springs: reservoir of thermophilic anaerobic bacteria producing hydrolytic enzymes
(Springer Tokyo, 2019)
Anaerobic cultivable microbial communities in thermal springs producing hydrolytic enzymes were studied. Thermal water samples from seven thermal springs located in the Andean volcanic belt, in the eastern and central ...
On Linear Analysis of the Power Flow Equations for DC and AC Grids with CPLs
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief presents an approximation of the power flow problem for alternating-current (ac) and direct-current (dc) distribution networks by using a linear representation of the hyperbolic constraints i=p/v ↔ II∗ ...
Control for EESS in Three-Phase Microgrids under Time-Domain Reference Frame via PBC Theory
(Institute of Electrical and Electronics Engineers Inc., 2019)
This brief presents a general form of designing passivity-based controllers for electrical energy storage systems (EESS) in three-phase microgrids (TP-MGs) under time-domain reference frame. The control strategy proposed ...
