VSC with direct PI power control for frequency compensation in a microgrid: A PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2019)
The power systems with low inertia such as microgrids require advanced control strategies to improve their performance. These type of grids use voltage source converters to interconnect renewable energy sources and storage ...
Wirtinger's Calculus for the Load Flow in Power Distribution Grids
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper shows a Wirtinger's-Calculus based loadflow methodology for power distribution grids. This approach allows to obtain an algorithm which works directly on the complex domain maintaining some useful symmetries and ...
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. ...
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 ...
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 ...
Flexible Liquid Crystal Polymer based complementary split ring resonator loaded quarter mode substrate integrated waveguide filters for compact and wearable broadband RF applications
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper the flexible Liquid Crystal Polymer (LCP) substrate is used to implement broadband wearable/foldable conformal bandpass filters that use compact cavity resonators working under the principle of quarter mode ...
Wireless passive sensing application using a cavity loaded evanescent mode half mode substrate integrated waveguide resonator
(2011)
In this work, an evanescent mode half mode substrate integrated waveguide (HMSIW) resonator is designed for a wireless passive sensing application at 5 GHz. The wireless pressure sensor has been implemented by placing a ...
