Anatomical Pathology of the Umbilical Cord and Its Maternal and Fetal Clinical Associations in 434 Newborns
(SAGE Publications Ltd, 2018)
Introduction: Umbilical cord (UC) abnormalities and their clinical relations in 434 newborns were analyzed. We had previously reported on clinical associations of long and short UCs with any kind of malformation. This study ...
Semiclassical self consistent treatment of the emergence of seeds of cosmic structure. the second order construction
(Institute of Physics Publishing, 2018)
In this work we extend the results of [1] where, Semiclassical Selfconsistent Configurations (SSC) formalism was introduced. The scheme combines quantum field theory on a background space-time, semiclassical treatment of ...
Passivity-based PI control of a SMES system to support power in electrical grids: A bilinear approach
(Elsevier Ltd, 2018)
A bilinear proportional-integral (PI) controller based on passivity-based formulations for integrating superconducting magnetic energy storage (SMES) devices to power ac microgrids is proposed in this paper. A cascade ...
Art, culture and etnodesarrollo:the pilot experience of mediation in bocas de ure, cordoba.
(2018)
This text presents the transversal technical and methodological challenges that came together in the participatory articulation of the Ethnodevelopment plan and the exercise of empirical community museography for the ...
Passivity-based control for battery charging/discharging applications by using a buck-boost DC-DC converter
(IEEE Computer Society, 2018)
In this paper, a passivity-based control (PBC) theory is applied to control a battery energy storage system (BESS) under current control mode by employing a bidirectional buck-boost DC-DC converter. The proposed controller ...
Nonlinear control for battery energy storage systems in power grids
(IEEE Computer Society, 2018)
This paper presents a nonlinear control strategy to integrate Battery Energy Storage Systems (BESS) in electrical power systems connected through Voltage Source Converters (VSCs). Exact feedback linearization control ...
Optimal conductor size selection in radial distribution networks using a mixed-integer non-linear programming formulation
(IEEE Computer Society, 2018)
In this paper a mixed-integer non-linear programming formulation for optimal conductor selection in radial distribution networks is proposed. The objective function in this problem corresponds to the minimization of power ...
Perception of working conditions on the quality of working life: Employees linked to health companies in Barranquilla, Colombia
(International Business Information Management Association, IBIMA, 2017)
Working conditions and their interaction on Quality of Working Life (QWL) perception in health sector employees from Barranquilla-Colombia were studied and modeled in a sample of 333 people aged between 16 and 73 years ...
Creating emotional proximity with the environment

Distributed energy resources integration in single-phase microgrids: An application of IDA-PBC and PI-PBC approaches
(Elsevier Ltd, 2019)
This paper presents a unified Hamiltonian formulation for controlling distributed energy resources (DERs)in ac single-phase microgrids (SP-MGs)via proportional-integral passivity-based control (PI-PBC), and interconnection ...
