V/f Control of Five-Phase Induction Motor Drive Fed from Cascaded H Bridge Multilevel Inverter
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)A multilevel inverter has its own advantages over normal inverters for high voltage applications such as reduced harmonics, and better AC output. Multi-levels are realized by different techniques e.g. Flying capacitors, ... -
Vaccine Development Against COVID-19 Prior to Pandemic Outbreaks, Using in vitro Evolution and Reverse Genetics
( Frontiers Media , 2020 , Article)Developing vaccines against COVID-19 during or after future pandemic outbreaks will be too slow to save lives. The opinion presented here is that we can anticipate the virus genomic structures that will emerge and cause ... -
Vaccine evaluation and genotype characterization in children infected with rotavirus in Qatar
( Springer Nature , 2023 , Article)Background: We characterized and identified the genetic and antigenic variations of circulating rotavirus strains in comparison to used rotavirus vaccines. Methods: Rotavirus-positive samples (n = 231) were collected and ... -
VacoNet: Variable and connected architecture for data center networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Todays data centers may contain tens of thousands of computers with progressively more specialized and expensive equipments. Thus, the research community has proposed various interconnect topologies e.g FatTree, Dcell and ... -
Vacuum structure and PT -symmetry breaking of the non-Hermetian (iϕ3) theory
( American Physical Society , 2017 , Article)In this work, we study the PT -symmetric (iϕ3) theory using the effective action formalism. To test the accuracy of the used technique, we apply it first to the PT -symmetric (−ϕ4) theory, where we reproduce the same results ... -
VALID-2: A practical modeling, simulation and verification software for distributed systems
( IEEE , 2004 , Conference Paper)Distributed systems verification is one of the main issues in software engineering. It is considered as the major field of the formal specification techniques. However, many difficulties remain. In fact, the principal ... -
Validated finite element models of premolars: A scoping review
( MDPI AG , 2020 , Article)Finite element (FE) models are widely used to investigate the biomechanics of reconstructed premolars. However, parameter identification is a complex step because experimental validation cannot always be conducted. The aim ... -
A Validated Reverse-Phase High Performance Liquid Chromatography (RP-HPLC) Method for the Quantification of Gamma-Tocotrienol in Tocotrienol Rich Fractions of Crude Palm Oil
( Bentham , 2021 , Article)Background: Palm oil and its constituents have wide applications in food, cosmet-ics and pharmaceutical industries. The tocotrienol-rich fractions of crude palm oil have drawn greater research interest in recent years due ... -
Validation and cultural adaptation of the Arabic versions of the Mini?Mental status examination - 2 and Mini-Cog test
( Dove Medical Press Ltd. , 2017 , Article)Introduction: The elderly population is increasing around the world, and the prevalence of dementia increases with age. Hence, it is expected that the number of people with dementia will increase significantly in the coming ... -
Validation of a Novel Fluorescent Lateral Flow Assay for Rapid Qualitative and Quantitative Assessment of Total Anti-SARS-CoV-2 S-RBD Binding Antibody Units (BAU) from Plasma or Fingerstick Whole-Blood of COVID-19 Vaccinees
( MDPI , 2022 , Article)Background: Limited commercial LFA assays are available to provide a reliable quantitative measurement of the total binding antibody units (BAU/mL) against the receptor-binding domain of the SARS-CoV-2 spike protein (S-RBD). ... -
Validation of a risk prediction model for COVID-19: the PERIL prospective cohort study.
( Future Medicine , 2023 , Article)This study aims to perform an external validation of a recently developed prognostic model for early prediction of the risk of progression to severe COVID-19. Patients were recruited at their initial diagnosis at two ... -
Validation of an Arabic version of the Diabetes Treatment Satisfaction Questionnaire in Qatar
( Elsevier , 2016 , Article)Aims: Several instruments evaluate patient-reported outcomes in diabetes mellitus (DM), but almost none are validated for use in Arabic language. The aim of this study is to test the psychometric properties and responsiveness ... -
