On the assumed inherent stability of semi-active control systems
(Elsevier, 2018-03)
Vibration control systems are usually classified into: passive, active and semi-active. Semi-active control systems are based on formerly passive mechanical devices, such as springs and dampers, whose characteristics are ...
Elastomers obtained by crosslinking of α,ω-bis(glycidylether) poly(dimethylsiloxane) as versatile platforms for functional materials
(Elsevier, 2016-12-19)
Elastomers with an interesting set of properties were synthesized by crosslinking α,ω-bis(glycidylether)poly(dimethylsiloxane,PDMS), using two different strategies. The first one was the anionic homopolymerization of ...
Improving Small-Signal Stability of Power Systems with Significant Converter-Interfaced Generation
(Institute of Electrical and Electronics Engineers, 2020-07-21)
This work presents a hierarchical control strategy to improve the stability of electrical networks with significant converter-interfaced generation (CIG). Due to the lack of inertia of CIG systems, these networks can undergo ...
Surface wave energy absorption by a partially submerged bio-inspired canopy
(IOP Publishing, 2018-05)
Aquatic plants are known to protect coastlines and riverbeds from erosion by damping waves and fluid flow. These flexible structures absorb the fluid-borne energy of an incoming fluid by deforming mechanically. In this ...
A Self-Adaptive Contractive Algorithm for Enhanced Dynamic Phasor Estimation
(Institute of Electrical and Electronics Engineers, 2020-05)
In this paper, a self-adaptive contractive (SAC) algorithm is proposed for enhanced dynamic phasor estimation in the diverse operating conditions of modern power systems. At a high-level, the method is composed of three ...
Mathematical and asymptotic analysis of thermoelastic shells in normal damped response contact
(Elsevier Science, 2021-12)
The purpose of this paper is twofold. We first provide the mathematical analysis of a dynamic contact problem in thermoelasticity, when the contact is governed by a normal damped response function and the constitutive ...
IDA-PBC controller design for grid connected Front End Converters under non-ideal grid conditions
(Elsevier Science Sa, 2017-01)
A passivity-based non-linear controller design for three-phase front-end converters used to connect renewable energy sources to the grid is proposed in this paper. The control objective is to inject all the generated power ...
Damping of Fe-Al Alloy Electrodeposited in an Ionic Liquid
(Universidade Federal de São Carlos, 2018-10)
Iron-Aluminium alloys were produced by the electro-deposition of iron-aluminium on a copper substrate. The electro-deposition process was done in the ionic liquid 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate, ...
Application of the modified IDA-PBC for shunt active power filters control
(John Wiley & Sons Ltd, 2016-09)
The design of a passivity-based nonlinear controller for a shunt active power filter to be used for the compensation of harmonic currents consumed by nonlinear loads is presented in this paper. The main objective of designed ...
Potential biological control pseudomonas sp. PCI2 against damping-off of tomato caused by Sclerotium Rolfsii
(Edizioni Ets, 2010-05)
Fluorescent Pseudomonas spp. isolated from the roots of healthy tomato plants were screened for their antagonistic activities against Sclerotium rolfsii, Alternaria alternata and Fusarium solani, three phytopathogenic fungi ...
