Contribution of Shell Eco-Marathon engineering design experience to soft skills development: A qualitative analysis in the Asian context
Abdulwahed M.; Ahmad S.; Hasna , Mazen; Ghani S.; Benammar M. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)Recent studies emphasize the needs of a wider set of skills engineers require than ever thought. Engineering curricula have been frequently criticized. Engineering design experience is one remedial way of heavy theory ... -
Harmonics minimization in 3-level inverter waveform and its FPGA realization
Ahmad S.; Ganie Z.A.; Ashraf I.; Iqbal A. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)The multilevel inverter (MLI) is more preferred for medium voltage high power application as it produces better quality voltage waveforms (stepped in nature) with reduced harmonic distortion (less THD), operates at less ... -
Low-order harmonics control in staircase waveform useful in high-power application by a novel technique
Ahmad S.; Al-Hitmi M.; Iqal A.; Ashraf I.; Meraj M.; Padmanaban S.... more authors ... less authors ( John Wiley and Sons Ltd , 2019 , Article)Few switching transition in high-power and medium-voltage application of power converters is desirable. The optimal pulse-width modulation (OPWM) at fundamental switching frequency offers a better quality waveform at lower ... -
On auxiliary information-based control charts for autocorrelated processes with application in manufacturing industry
Ahmad S.; Riaz M.; Hussain S.; Abbasi S.A. ( Springer London , 2019 , Article)Multivariate autoregressive (MAR) models are an attractive choice for applications in the processes related to finance, medical, and industry. For the monitoring of such processes, control chart is the most important and ... -
Selected harmonics elimination in multilevel inverter using improved numerical technique
Ahmad S.; Iqbal A.; Al-Ammari R.; Abu-Rub H. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)For medium voltage high power application the modulation technique for power converters based on pre-computed Pulse Width Modulation (PWM) switching patterns can be very useful since the generated harmonic content can be ... -
Selective harmonic elimination in awide modulation range using modified Newton-raphson and pattern generation methods for a multilevel inverter
Al-Hitmi M.; Ahmad S.; Iqbal A.; Padmanaban S.; Ashraf I. ( MDPI AG , 2018 , Article)Considering the aim of having low switching losses, especially in medium-voltage and high-power converters, the pre-programmed pulse width modulation technique is very useful because the generated harmonic content can be ... -
Selective harmonics elimination in multilevel inverter by a derivative-free iterative method under varying voltage condition
Ahmad S.; Meraj M.; Iqbal A.; Ashraf I. ( ISA - Instrumentation, Systems, and Automation Society , 2019 , Article)Selective Harmonics Elimination Pulse width modulation (SHE PWM) presents an alternative modulation technique to operate medium voltage medium and high power converters as it reduces the switching losses. SHE PWM generates ...
