Probabilistic power flow analysis of power systems with PV and wind using monte carlo method
(Institute of Electrical and Electronics Engineers Inc., 2023)
With the increase in renewable energy systems, the increasing uncertainties in power systems make the analysis with deterministic power flow method insufficient. Probabilistic load flow allows us to see the distribution ...
Challenges and future perspectives on production, storage technologies, and transportation of hydrogen: A review
(Wiley, 2024)
Hydrogen plays an essential role in the energy-transition process. Even though currently almost 80-96% of hydrogen is produced from fossil fuel sources in the world, the exciting feature of hydrogen is that it can be ...
Comparative implementation of thermoelectric coolers in transformer cooling
(Taylor & Francis Ltd., 2023)
In this study, using a comprehensive experimental methodology, thermoelectric coolers (TECs) are used for transformer cooling in contrast to classical methods such as air, oil, and water. The effects of this operation are ...
New modified carrier-based level-shifted PWM control for NPC rectifiers considered for implementation in EV fast chargers
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)
In this study, the aim is to evaluate three-phase (3ϕ) AC/DC neutral point-clamped (NPC) power factor-corrected (PFC) multilevel converter performance for electric vehicle (EV) fast chargers. Power factor correction for ...
Enhancing filtration performance of submicron particle filter media through bimodal structural design
(Wiley, 2023)
Depth filtration is a widely utilized mechanism for submicron aerosol filtration using disposable filter cartridges and facemasks. The filter media should be carefully engineered to reach high filtration efficiency and ...
The role of intrinsic atomic defects in a Janus MoSSe/XN (X = Al, Ga) heterostructure: a first principles study
(Institute for Condensed Matter Physics, 2023)
The interactions between different layers in van der Waals heterostructures have a significant impact on the electronic and optical characteristics. By utilizing the intrinsic dipole moment of Janus transition metal ...

(Elsevier Gmbh, 2013)
The effects of W doping on the characteristical properties of SnO2 thin films prepared by sol-gel spin coating method were investigated. the SnO2 thin films were deposited at various W doping ratios and characterized by ...
Comparative study of single-phase multilevel cascaded transformerless inverters with different modulation methods
(Elsevier, 2024)
This paper presents an in-depth exploration of a single -phase multilevel cascaded H5 (CH5) transformerless inverter employing both phase-shifted PWM (PS-PWM) and level-shifted PWM (LS-PWM) methodologies. A comparative ...
Electromagnetic interference shielding using biomass-derived carbon materials
(Elsevier, 2024)
The growing concern over electromagnetic radiation (EMR) emitted by electronic devices has raised awareness of its adverse effects on human health and electronic operations, thus increasing interest in electromagnetic ...
Investigating the informative brain region in multiclass electroencephalography and near infrared spectroscopy based BCI system using band power based features
(Taylor & Francis Ltd., 2024)
In recent years, various brain imaging techniques have been used as input signals for brain-computer interface (BCI) systems. Electroencephalography (EEG) and near-infrared spectroscopy (NIRS) are two prominent techniques ...
