Investigating the informative brain region in multiclass electroencephalography and near infrared spectroscopy based BCI system using band power based features
Ergün, Ebru; Aydemir, Önder; Korkmaz, Onur Erdem (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 ... -
Measurement and mapping of the GSM-based electromagnetic pollution in the Black Sea region of Turkey
Tüysüz, Burak; Mahmutoğlu, Yiğit (Taylor & Francis Inc, 2017)Electromagnetic pollution caused by mobile communication devices, a new form of environmental pollution, has been one of the most concerning problems to date. Consequences of long-term exposure to the electromagnetic ... -
A new evolutionary preprocessing approach for classification of mental arithmetic based EEG signals
Ergün, Ebru; Aydemir, Önder (Springer, 2020)Brain computer interface systems decode brain activities from electroencephalogram (EEG) signals and translate the user's intentions into commands to control and/or communicate with augmentative or assistive devices without ... -
Production of ultrafine PVDF nanofiber-/banonet-based air filters via the electroblowing technique by employing PEG as a pore-forming agent
Toptaş, Ali; Çalışır, Mehmet Durmuş; Kılıç, Ali (PMC, 2023)Particles with diameters smaller than 2.5 μm (PM2.5) can penetrate the respiratory system and have negative impacts on human health. Filter media with a porous surface and nanofiber/ nanonet structure demonstrate superior ... -
