5-level Cascaded H-Bridge Multilevel microgrid Inverter applicable to multiple DG resources with power quality enhancement capability
(2015-01-01)
This paper presents a 5-level Cascaded H-Bridge Multilevel Inverter (CHMI) able to perform several tasks and applicable to a microgrid with multiple local power sources. The current control strategy is based on the ...
Is income area level associated with blood pressure in adults regardless of individual-level characteristics? A multilevel approach
(ELSEVIER SCI LTDOXFORD, 2012)
This population-based health survey was carried out in Florianopolis, Brazil, to assess the association between adult systolic blood pressure (SBP) and contextual income level, after controlling for potential individual-level ...

Factors That Influence Data Quality in Caries Experience Detection: A Multilevel Modeling Approach
(KARGER, 2010)
Caries experience detection is prone to misclassification. For this reason, calibration exercises which aim at assessing and improving the scoring behavior of dental raters are organized. During a calibration exercise, a ...
Optimal ZCS Modulation for BidirectionalHigh-Step-Ratio Modular Multilevel dc-dc Converter
(2021)
Recent developments in dc powered technologies have increased interest in highly efficient dc-dc converters, especially at high voltage and high-step voltage ratios. Modular multilevel converters (MMCs) are an attractive ...
Sliding Mode Control Of The Modular Multilevel Converter
(2019)
The modular multilevel converter (MMC) has become the most promising converter topology for medium- and high-power applications. In this paper, a sliding mode control (SMC) based method is proposed for the MMC. Based on ...
Training program evaluation in non-standardized context: Complementarity across Factorial and Multilevel Analysis to obtain construct validity evidences.
(2015)
Program evaluation is usually applied to non-standardized intervention contexts. This implies, among others, deficiencies of: a) validated theoretical models
