A power system uses control mechanisms to supply the continuous variations in demand, without difference between generation and demand and to deliver energy with minimum requirements of frequency, voltage and reliability. ...

We investigate the onset and development of vortical flow disturbances introduced into the wake of a horizontally fixed flat-plate by means of the controlled motion of a trailing edge flap. The vibrating mechanics of the ...

Self-assembled monolayers (SAMs) of alkylthiols on gold have called considerable attention due to several applications in the modification and control of surface properties, such as wettability, tribology, and biocompatibility. ...

Symmetry and localization properties of defect modes of a one-dimensional bicomponent magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a periodic array of nanostripes, where stripes ...

O objetivo desse estudo foi avaliar o efeito do enriquecimento de piso em gaiolas tradicionais de arame sobre os indicadores comportamentais e fisiológicos de estresse em coelhos no período de verão. Foram utilizados ...

Ferro- or piezoelectrets are dielectric materials with two elastically very different macroscopic phases and electrically charged interfaces between them. One of the newer piezoelectret variants is a system of two ...

RESUMEN: En este trabajo se presenta el estudio y control de cuatro sistemas mecánicos subactuados de tipo péndulo invertido, a saber: Péndulo de Furuta (PF), Péndulo con Rueda Inercial (PRI), Péndulo Invertido Sobre Carro ...

Background: Alcohol intake is associated with oral diseases and bone changes including alveolar bone loss in humans and in experimental animals. The main aim of the present study is to assess the effect of long-term alcohol ...
