Estimation of Concentration and Load of Suspended Bed Sediment in a Large River by Means of Acoustic Doppler Technology
(American Society of Civil Engineers, 2014-03)
The standard experimental methods used for sampling suspended loads in large rivers are usually time consuming, unsafe, rather expensive, and have a limited spatial resolution. Acoustic Doppler current profilers (ADCPs), ...
Hypertension linked to allostatic load: From psychosocial stress to inflammation and mitochondrial dysfunction
(Taylor & Francis Ltd, 2019-03)
Although a large number of available treatments and strategies, the prevalence of cardiovascular diseases continues to grow worldwide.émergingévidence supports the notion of counteracting stress as a critical component of ...
A review of the suspended sediment budget at the confluence of the Paraná and Paraguay Rivers
(John Wiley & Sons Ltd, 2009-10)
Abstract. In this paper the sediment budget at the confluence of the Paraná-Paraguay rivers, is updated on the base of new suspended sediment concentrations data, measured during the nineties at carefullly located ...
Predictive current control strategy with imposed load current spectrumIEEE TRANSACTIONS ON POWER ELECTRONICS
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2016)
High-performance control of a three-phase voltage-source converter including feedforward compensation of the estimated load current
(Pergamon-Elsevier Science Ltd, 2009-08)
In this paper a new control strategy for voltage-source converters (VSC) is introduced. The proposed strategy consists of a nonlinear feedback controller based on feedback linearization plus a feedforward compensation of ...
Digital Control of a Three-Phase Four-Leg Inverter to Feeds Non-Linear Loads
(Institute of Electrical and Electronics Engineers, 2021-05)
This paper presents a new control strategy for three-phase four-leg inverters, to meet the requirements of total and individual harmonic content imposed by IEC 61000-2-2 when the inverter feeds a non-linear reference load ...
Anomalous ocean load tide signal observed in lake-level variations in Tierra del Fuego
(American Geophysical Union, 2009-03)
We demonstrate the application of a 100 km long lake as a sensor for studying the tidal effects on Tierra del Fuego main island. The lake-level variations observed in Lago Fagnano reflect both the direct response to the ...
Impact of nonlinear lighting loads on the neutral conductor current of low voltage residential grids
(MDPI AG, 2020-09)
In the last decade, mainly due to political incentives towards energy efficiency, the share of lamps with power electronic interfaces, like Compact Fluorescent Lamps (CFL) and Light Emitting Diode (LED) lamps, has significantly ...
Control Methods for Single-phase Voltage Supply with VSCs to Feed Nonlinear Loads in Rural Areas
(Universidad Tecnológica de Bolivar, 2020-12)
Este artículo aborda el problema de la generación de voltaje sinusoidal en cargas lineales utilizando un inversor de fuente de voltaje (VSI). La estructura port-Hamiltoniana en lazo abierto se utiliza para diseñar un ...
Software Sensor-Based STATCOM Control under Unbalanced Conditions
(Institute of Electrical and Electronics Engineers, 2009-07-24)
A new control strategy for static compensators (STATCOMs) operating under unbalanced voltages and currents is presented in this paper. The proposed strategy adopts a state observer (software sensor) to estimate ac voltages ...
