Differential evolution-based pulse-width modulation technique for multiphase MC
Ali M.; Iqbal A.; Anees M.A.; Khan M.R.; Rahman K.; Ayyub M.... more authors ... less authors ( Institution of Engineering and Technology , 2019 , Article)This paper addresses multiphase matrix converter (MPMCs) modulated with Venturini's classical scalar approach. The solution to obtain time-varying modulation functions was limited to 3 × 3 configuration, which was later ... -
Fourier Transform Infrared (FT-IR) and Laser Ablation Inductively Coupled Plasma–Mass Spectrometry (LA-ICP-MS) Imaging of Cerebral Ischemia: Combined Analysis of Rat Brain Thin Cuts Toward Improved Tissue Classification
Balbekova A.; Lohninger H.; van Tilborg G.A.F.; Dijkhuizen R.M.; Bonta M.; Limbeck A.; Lendl B.; Al-Saad K.A.; Ali M.; Celikic M.; Ofner J.... more authors ... less authors ( SAGE Publications Inc. , 2018 , Article)Microspectroscopic techniques are widely used to complement histological studies. Due to recent developments in the field of chemical imaging, combined chemical analysis has become attractive. This technique facilitates a ... -
Genetic Algorithm based SHE-PWM for 1- ø and 3- ø Voltage Source Inverters
Kumari, M.; Ali, M.; Ahmad, Salman; Ashraf, I.; Azeem, A.; Tariq, M.; Bin Arif, M. Saad; Iqbal, Atif... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In medium voltage high power application of voltage source inverter (VSI), low switching frequency pulse width modulation (LSPWM) techniques offer better efficiency and better thermal management as the switching loss ... -
Modulation with metaheuristic approach for cascaded-MPUC49 asymmetrical inverter with boosted output
Lodi, K. A.; Ali, M.; Tariq, M.; Meraj, Mohammad; Iqbal, Atif; Chakrabortty, R. K.; Ryan, M. J.... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)This work introduces a 49-level Asymmetrical Inverter (AMLI) with boosted output based on the cascaded operation of two 7-Level Modified Packed U-Cell inverters (MPUC-7). The converter is capable of operation with a boosted ... -
Pass-fail decisions for borderline performers after a summative objective structured clinical examination
Ali M.; Pawluk S.A.; Rainkie D.C.; Wilby K.J. ( American Association of Colleges of Pharmacy , 2019 , Article)Objective. To determine what expert assessors value when making pass-fail decisions regarding pharmacy students based on summative data from objective structured clinical examinations (OSCE), and to determine the reliability ... -
Prevalence and correlates of autism spectrum disorder in Qatar: a national study
Alshaban F.; Aldosari M.; Al-Shammari H.; El-Hag S.; Ghazal I.; Tolefat M.; Ali M.; Kamal M.; Abdel Aati N.; Abeidah M.; Saad A.H.; Dekair L.; Al Khasawneh M.; Ramsay K.; Fombonne E.... more authors ... less authors ( Blackwell Publishing Ltd , 2019 , Article)Background Few epidemiological data on autism spectrum disorders (ASD) exist for Arabic countries. We conducted the first survey of ASD in Qatar, a population with high consanguinity level. Methods This cross‐sectional ... -
Scalar Modulation Strategy for Even-Phase-Output Matrix Converter
Ali, M.; Khan, M. R.; Ayyub, M.; Rahman, K.; Iqbal, Atif ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Even phase drives in conjunction with multiphase matrix converter is a smart solution in connecting them to a three-phase source. It reduces the area required to install such drive due to the omission of bulky dc-link ...
