Measurement and mapping of the GSM-based electromagnetic pollution in the Black Sea region of Turkey
(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 ...
Etkin epoklar ile motor hayaline dayalı EEG işaretlerinin sınıflandırma doğruluğunun artırılması
(2018)
Beyin bilgisayar arayüzleri (BBA) sadece beyinde üretilen işaretleri kullanarak çeşitli elektronik cihazları kullanmayı olanaklı hale getiren sistemlerdir. Bu sistemlerin yüksek başarımlı olabilmesi için bu işaretlerden ...
Multi-band plasmonic platform utilizing UT-shaped graphene antenna arrays
(Springer, 2018)
In this work, we introduce a plasmonic platform based on UT-shaped graphene antenna arrays. the proposed multi-resonant platform shows three different resonances, which can be independently tuned. the physical origin of ...
Comparison of different controllers and stability analysis for photovoltaic powered buck-boost DC-DC converter
(Taylor & Francis Inc, 2018)
In this study, proportional integral (PI), fuzzy logic (FL), and sliding mode (SM) control of DC-DC buck-boost converter are presented. the obtained results were compared for these controller methods. the converter system, ...
A new target radar cross section based passive radar surveillance receiver positioning algorithm on real terrain maps
(Spolecnost Pro Radioelektronicke Inzenyrstvi, 2018)
Placing surveillance receivers on passive radar systems is a complex task because of the dependence on third party vendors. This paper presents an efficient and robust algorithm for positioning passive radar surveillance ...
A passive acoustic based system to locate leak hole in underwater natural gas pipelines
(Academic Press Inc Elsevier Science, 2018)
Underwater natural gas pipelines can be punctured for a variety of reasons, but the most notable are corrosion and aging. This study proposes a novel passive acoustic based system, to detect acoustic signals, locate the ...
Decoding of binary mental arithmetic based near infrared spectroscopy signals
(Ieee, 2018)
There has been an increase interest for functional near-infrared spectroscopy (MRS) in recent years since it is a non-invasive technique as well as few restrictions to the subjects and not affected by electrical noise. in ...
Classification of electroencephalography signals recorded during olfaction of some spices
(Ieee, 2018)
Responses to different information from the sensory organs of the brain can be analyzed by various brain imaging techniques. Among these techniques, electroencephalography (EEG) is widely used because it is performed at a ...
Classification of brain responses to the various spice odors
(Ieee, 2018)
Since one of the main goal of the human brain is to take and evaluate stimuli that comes from sensory organs, it is possible to measure their functionality. in this study we classified the electroencephalography signals ...
Efficiency improvement for a DC-DC quadratic power boost converter by applying a switch turn-off lossless snubber structure based on zero voltage switching
(Kaunas Univ Technology, 2018)
So as to keep the converter in small size, high switching frequencies are normally used. As a result, in higher frequencies, switching losses seriously affect the efficiency. Current and voltage stresses on power switch ...
