Small-Signal Stability in Low-Voltage DC-Grids
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents a general methodology for small signal stability analysis in low voltage de grids considering four type of terminals, namely: constant power, constant voltage, constant current and constant impedance. ...
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 ...
Isohyetal maps of daily maximum rainfall for different return periods for the Colombian Caribbean Region
(MDPI AG, 2019)
In Colombia, daily maximum multiannual series are one of the main inputs for design streamflow calculation, which requires performing a rainfall frequency analysis that involves several prior steps: (a) requesting the ...
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 ...
Genetic Advances in Post-traumatic Stress Disorder
(Elsevier Doyma, 2018)
Post-traumatic stress disorder, or PTSD, is a condition that affects a subgroup of individuals that have suffered a previous traumatic event capable of generating changes at a psychological and behavioural level. These ...
Two-dimensional Einstein manifolds in geometrothermodynamics
(2013)
We present a class of thermodynamic systems with constant thermodynamic curvature which, within the context of geometric approaches of thermodynamics, can be interpreted as constant thermodynamic interaction among their ...
Influence of sex and task difficulty on switching attention
(Universitat de Barcelona, 2017)
In this paper, we study complex or executive attention based on sex and difficulty of switching attention task. An experimental study was carried out using a mixed complex 2 × 4 design in which 48 students participated ...
Acquisition and Analysis of Cognitive Evoked Potentials using an Emotiv Headset for ADHD Evaluation in Children
(Institute of Electrical and Electronics Engineers Inc., 2019)
Attention-deficit/hyperactivity disorder (ADHD) is a neurological condition that affects the quality of life of the patients. It can be diagnosed using a combination of psychological tests. In addition to that, the brain ...
Rasch Analysis of the Q-CHAT in Colombian Toddlers with Autism Spectrum Disorder
(Springer New York LLC, 2019)
The objective of this study was the validation of the Colombian version of The Quantitative Checklist for Autism in Toddlers (Q-CHAT) by means of the Rasch Rating Scale Model. The Q-CHAT was applied to parents of 100 ...
An infinite family of relativistic magnetized finite thin disks
(Institute of Physics Publishing, 2011)
An infinite family of relativistic finite thin disk model with magnetic field is presented. The model is obtained for solving the Einstein-Maxwell equations for static spacetimes by means of the Horsk-Mitskievitch generating ...
