A Proposed Technique for Harmonic Reduction of Three Phase Cascade Multilevel Inverter (CMLI)

Journal of Engineering and Sustainable Development, 2013
Inverters are widely used in many applications & the object of using the inverter is produce ac voltage with controllable magnitude & frequency. But the inverters where found in both the industrial motor drive industry & in the emerging distributed ...

Modelling Suicide‐Related Communication Dynamics: A Socio‐Cybernetic Framework for Governance

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Suicide‐related phenomena (SPS) are often approached through individual‐level risk factors or moral framings, yet their population‐level dynamics depend critically on how ‘suicide’ becomes observable, circulates and is governed across functionally differentiated systems.

The Hare and the Tortoise in Ecological L2 Learning: Distributed Practice Effects in Vocabulary and Grammar

TESOL Quarterly, EarlyView.
Abstract Research on the distributed practice effect, that is the impact of different intervals between learning sessions, has investigated both intentional and incidental learning of second language vocabulary and grammar targets. This research is complex and has produced conflicting findings: whereas robust effects have been shown for intentional ...

Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

High Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

Controlling common-mode voltages in multilevel inverters

, 2008
This paper proposes a novel method based on pulse width modulation techniques to reduce and control the common-mode voltage in three-phase multilevel inverters. Besides controlling the common-mode voltage, this method is capable of controlling capacitors

Determinants of case outcomes in Rwanda's postgenocide gacaca courts

Criminology, EarlyView.
Abstract Transitional justice trials have become a central mechanism for addressing mass violence and human rights violations, yet little is known about the determinants of case outcomes within these courts—particularly in domestic contexts. This study examines Rwanda's gacaca courts, a localized transitional justice system that tried people suspected ...

A balance between stability and flexibility: Adaptive patterns of self‐regulated learning processes shape game‐based learning

British Journal of Educational Technology, EarlyView.
Abstract To ensure learning efficiency in game‐based learning (GBL), learners must regulate cognitive, affective, metacognitive and motivational (CAMM) processes, collectively known as self‐regulated learning (SRL). SRL is dynamic and non‐linear, characterized by regulatory patterns and CAMM interactions that lead to macro‐level SRL behaviours. In this
