Motion of test particles in a magnetized conformastatic background
(World Scientific Publishing Co. Pte. Ltd., 2018)
A class of exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely determined by a harmonic function only. The motion of ...
The role of women in Rainbow of Peace, by Fray Pedro de Santa María y Ulloa
(Universidad Nacional de Educacion a Distancia, 2017)
This article analyzes the role of women and the Virgin Mary in the vision of the Dominican friar of the XVII century, Fray Pedro de Santa María y Ulloa, the highest representative of the devotion to the Marian prayer in ...
Descriptive analysis of female representations in the Spanish peseta
(Ediciones Hecate, 2017)
A numismatic review about Spanish peseta coins minted between 1869 and 2001 (except for the commemorative pieces) which representing female figures is presented in this scientific article. This paper attempts to locate and ...
Incentivizing alternative fuel vehicles: the influence of transport policies, attitudes and perceptions
(Springer New York LLC, 2018)
This paper aims to evaluate the influence of policies, attitudes and perceptions when incentivizing alternative fuel vehicles. The impact of possible policies such as gasoline taxes increases, purchase price subsidies, tax ...
Control of a SMES for mitigating subsynchronous oscillations in power systems: A PBC-PI approach
(Elsevier Ltd, 2018)
This paper proposes a methodology to control the active and reactive power of a superconducting magnetic energy storage (SMES) system to alleviate subsynchronous oscillations (SSO) in power systems with series compensated ...
Time-Domain Analysis for Current Control in Single-Phase Distribution Networks Using SMES Devices With PWM-CSCs
(Taylor and Francis Inc., 2018)
This paper presents a time-domain analysis for current control in single-phase distribution networks using superconducting magnetic energy storage devices connected through pulse-width modulated current source converters. ...
A New Approach for the Monte-Carlo Method to Locate and Size DGs in Distribution Systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper proposes a new approach for a Parallel implementation of Monte-Carlo method aimed for optimal location and sizing of distributed generators in distribution networks. In this approach, a reduction of the solution ...
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 ...
Logistic regression models for predicting daily airborne Alternaria and Cladosporium concentration levels in Catalonia (NE Spain)
(Springer New York LLC, 2019)
Alternaria and Cladosporium are the most common airborne fungal spores responsible for health problems, as well as for crop pathologies. The study of their behavior in the air is a necessary step for establishing control ...
