Investigations of multi-carrier pulse width modulation schemes for diode free neutral point clamped multilevel inverters
(
Korean Institute of Power Electronics
, 2019 , Article)
Multilevel Inverters (MLIs) are widely used in medium voltage applications due to their various advantages. In addition, there are numerous types of MLIs for such applications. However, the diode-less 3-level (3L) T-type ...
Hybrid-boost modular multilevel converter-based medium-voltage multiphase induction motor drive for subsea applications
(
Korean Institute of Power Electronics
, 2019 , Article)
This paper proposes a hybrid-boost Modular Multilevel Converter (MMC) for the Medium-Voltage (MV) Variable Speed Drives (VSDs) employed in subsea applications, such as oil and gas recovery. In the presented architecture, ...
Evaluation model for e-tourism product: A hidden Markov model-based algorithm
(
Inderscience
, 2014 , Article)
Nowadays, e-tourism is widely pronounced as a kind of web marketing for tourism businesses. Tourist agencies and tourism service providers are able to access their customers directly in a cost-effective way. In this context, ...
Measuring time-varying information flow in scalp EEG signals: Orthogonalized partial directed coherence
(
IEEE
, 2014 , Article)
This study aimed to develop a time-frequency method for measuring directional interactions over time and frequency from scalp-recorded electroencephalographic (EEG) signals in a way that is less affected by volume conduction ...
Treatment as prevention for hepatitis C virus in Pakistan: Mathematical modelling projections
(
BMJ Publishing Group
, 2019 , Article)
Objective Direct-Acting antivirals have opened an opportunity for controlling hepatitis C virus (HCV) infection in Pakistan, where 10% of the global infection burden is found. We aimed to evaluate the implications of five ...
Effect of operational parameters on distillate flux in direct contact membrane distillation (DCMD): Comparison between experimental and model predicted performance
(
Elsevier B.V.
, 2014 , Article)
Membrane distillation (MD) is a thermally driven process where hydrophobic membranes are used to separate saline hot feed solution and cold stream of water and allow water to evaporate due to temperature difference. This ...
Generalized spatial aliasing solution for the dispersion analysis of infinitely periodic multilayered composites using the finite element method
(
American Society of Mechanical Engineers
, 2017 , Article)
The finite element (FE) method offers an efficient framework to investigate the evolution of phononic crystals which possess materials or geometric nonlinearity subject to external loading. Despite its superior efficiency, ...
Field evaluation of membrane distillation technologies for desalination of highly saline brines
(
Elsevier
, 2014 , Article)
Membrane distillation (MD) is a hybrid thermal-membrane desalination process that uses low-grade waste heat and hydrophobic membrane to produce high quality distillate. The MD process can treat highly saline brines that ...
