A Discontinuous PWM Method for Balancing the Neutral Point Voltage in Three-Level Inverter-Fed Variable Frequency Drives
( IEEE , 2008 , Article)The paper describes a new discontinuous carrier-based pulsewidth modulation (PWM) method for use in variable frequency drives (VFD) driven by three-level inverters. The method introduces three different switching patterns ... -
Discontinuous space vector pulse width modulation techniques for a five-phase quasi Z-source inverter
( IEEE , 2015 , Conference Paper)In this paper, discontinuous space vector pulse width modulation for a five-phase quasi Z-source inverter is presented. Two schemes are introduced for the continuous SVM of five-phase qZSI (SVQ1 & SVQ2) and two schemes of ... -
Discourse relation recognition in translation: a relevance-theory perspective
( Routledge , 2016 , Article)The use of discourse markers in argumentation is an area in which the rhetorical traditions of Arabic and English diverge. While English allows implicit logical links, Arabic demands explicitly marked coherence. Such ... -
Discoursing ‘democratic knowledge’ & knowledge production in North Africa
( Taylor & Francis , 2015 , Other)North Africa (interchangeably used with the term ‘Maghrib’) has historically featured as a contributor to Euro-Med cultures and civilisations. Mesopotamia, Egypt and Phoenicia all at one point in time or another mediated ... -

Discovering citizens reaction toward e-government: factors in e-government adoption
( TECSI FEA USP , 2014 , Article)E-government has been considered as one approach for changing the face of government in the eyes of the citizenry. Therefore, citizens’ socialization in relation to their engagement with e-government should be explored. ... -
Discovering influential users in micro-blog marketing with influence maximization mechanism
(2012 , Conference Paper)Micro-blog marketing has become a main business model for social networks nowadays. On social networking sites (e.g., Twitter), micro-blog marketing enables the advertisers to put ads to attract customers to buy their ... -
Discovery and systematic characterization of risk variants and genes for coronary artery disease in over a million participants
( Nature Research , 2022 , Article)The discovery of genetic loci associated with complex diseases has outpaced the elucidation of mechanisms of disease pathogenesis. Here we conducted a genome-wide association study (GWAS) for coronary artery disease (CAD) ... -
Discovery of new genomic regions and candidate genes implicated in the natural variation of barley peduncle length and plant height
( Springer Nature , 2024 , Article)The cereal plant barley (Hordeum vulgare) has high nutritional content and special characteristics that allow it to withstand adverse weather conditions. The peduncle’s developmental properties under dry (drought and heat) ... -
Discovery of new therapeutic targets in ovarian cancer through identifying significantly non-mutated genes
( BioMed Central Ltd , 2022 , Article)Background: Mutated and non-mutated genes interact to drive cancer growth and metastasis. While research has focused on understanding the impact of mutated genes on cancer biology, understanding non-mutated genes that are ... -
Discovery of Novel Pyridine Derivatives as Anti-Cancer Agents
(2015 , Master Thesis)The International Agency for Research on Cancer indicated that cancer burden was raised in 2012 to 14.1 million incidence cases and 8.2 mortality cases. Consequently, novel approaches are urgently required for further ... -
Discrepancy in MALDI-TOF MS identification of uncommon Gram-negative bacteria from lower respiratory secretions in patients with cystic fibrosis
( Dovepress , 2015 , Article)Introduction: Early identification of microbial organisms from respiratory secretions of patients with cystic fibrosis (CF) is important to guide therapeutic decisions. The objective was to compare the accuracy of ... -
Discrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
( American Society of Civil Engineers (ASCE) , 2020 , Article)The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ... -
Discrete Element Modeling Of Railroad Ballast Under Simulated Train Loading
(2019 , Master Thesis)Ballasted tracks have been widely used in many countries around the world. Ballast layer is the main element in ballasted track. After service, ballast aggregates degrade and deform. Periodical maintenance for ballast ... -
Discrete event simulation for sustainable batch production in food processing
( Dime University of Genoa , 2016 , Conference Paper)In a world faced with depleting resources and hazardous biodegradable food wastes, an efficient planning for the food processing operation is crucial to avoid the adverse potential impact of excess food production. This ... -
Discrete Input Signaling for Secure MISO VLC Systems with Randomly Located Eavesdroppers
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)We study in this paper the secrecy performance of the multiple-input single-output (MISO) visible light communication (VLC) channel in the presence of randomly located eavesdroppers. We consider a system model comprising ... -
Discrete particle translation gradient concept to expose strain localisation in sheared granular materials using 3D experimental kinematic measurements
( ICE Publishing , 2018 , Article)It is well known that the constitutive behaviour of granular materials is influenced by strain localisation into zones of intensive shearing, known as shear bands. The failure mode of specimens tested under axisymmetric ... -
Discrete time domain analysis and optimal design of stationary frame AC current controllers with active damped LCL Filter for high power applications
( IEEE Computer Society , 2014 , Conference Paper)Due to the large variety of renewable power sources, power electronics play an important role in energy conversion. Different power converter topologies are used to interface distributed power generation systems (DPGS) ... -
