This study uses global numerical model results of ocean and atmospheric circulation, as well as local wind, wave and current meter data, to investigate the structure of the ocean and coastal circulation potentially associated with the transport of oil that affected thousands of kilometers of the Brazilian coast in 2019. Our analysis suggests the oil was brought close to the continental shelf sometime in August 2019 by the southern branch of South Equatorial Current, and was initially advected towards ...

Hysterectomy is a widely performed surgery and neuraxial anesthesia with intrathecal morphine provides superior quality of recovery. Postoperative nausea and vomiting (PONV) is a frequent problem with intrathecal morphine use. Although palonosetron is effective for prevention of PONV after general anesthesia, its efficacy after neuraxial anesthesia has not been established. This study was conducted to compare the use of palonosetron with ondansetron for PONV prophylaxis in patients at a high risk ...

This paper presents a phase-locked loop algorithm adequate for applications regarding single-phase power grids. The proposed approach is based on the correlation of the input signal with a complex one obtained from an adaptive filter aiming at minimizing computational burden and increasing accuracy when compared with a former algorithm previously proposed in the literature. Thus, it is possible to obtain high disturbance rejection, especially when dealing with the presence of subharmonics and interharmonics ...

The increasing penetration of wind energy conversion systems (WECSs) based on the doubly-fed induction generator (DFIG) has raised serious concerns about the stability of modern power systems. One important issue is the frequency control of interconnected networks, which may become more complex owing to the low inertia of wind turbines. In this context, this work presents a novel frequency control approach that associates the grid-side converter (GSC) with a synchronverter. To assess the performance ...

Voltage sags may affect the accurate operation of several equipment connected to power systems. A typical example is the doubly-fed induction generator (DFIG), which is often employed in wind energy conversion systems (WECSs). Since the stator windings are directly connected to the power grid, the generator becomes very sensitive to such power quality disturbances. In this context, this work proposes a fast and accurate algorithm for the detection of voltage sags based on the aggregate value concept. ...

This study presents an auxiliary cell that can be applied to the single-phase full-bridge inverter. The cell employs two auxiliary switches, two auxiliary diodes, one resonant capacitor, and one resonant inductor, as it can be used in both inverter legs so that switching losses are minimised, thus implying increased efficiency and low electromagnetic interference levels. Three possible configurations are investigated and theoretical analyses are carried out. Besides, the control strategy provides ...
