Maniobras de llenado y vaciado en grandes conducciones. Aplicación a una tubería de fundición DN400 en Massamagrell (Valencia, España)
(2020-01-31)
Air pockets inside hydraulic installations during filling and emptying processes can generate pressure surges and negative pressure, respectively. Serious damages can be occurred in pipelines. In order to analyse hydraulic ...
Passivity-based control of islanded microgrids with unknown power loads
(2020-10-12)
In this paper, the control problem of microgrids (MGs)operating in islanded mode is approached from a passivity-based control perspective. A control scheme is proposed that, relying only on local measurements for the power ...
PI-PBC Approach for Voltage Regulation in Cuk Converters with Adaptive Load Estimation
(2020-11-25)
This paper proposes a proportional-integral passivity-based controller (PI-PBC) for supporting voltage in linear loads integrated with Ćuk converters. An adaptive load estimator is also employed to avoid current measurements ...

(2020-04-04)
School violence alludes to peer bullying and aggression in school. The field of communication has studied school violence by analyzing the influence of media and interpersonal relationships on aggressive behaviors. This ...
A Comparative Study on Power Flow Methods for Direct-Current Networks Considering Processing Time and Numerical Convergence Errors
(2020-12-03)
This study analyzes the numerical convergence and processing time required by several classical and new solution methods proposed in the literature to solve the power-flow problem (PF) in direct-current (DC) networks ...
Environmental life cycle assessment for a large-scale gold mining
(2020-07)
Mining, generally speaking, is an industry which consumes water in an intensive way, and when metal fineness is less and more mineral is extracted, it will also increase the consumption of this source. Just in the last 40 ...
