III-nitride terahertz photodetectors for the reststrahlen gap of intersubband optoelectronics
(Spie-Int Soc Optical Engineering, 2017)
We report the development of terahertz intersubband photodetectors based on GaN/AlGaN quantum wells, covering the frequency range that is fundamentally inaccessible to existing III-V semiconductor devices due to Reststrahlen ...
Classification of EEG based BCI signals imagined hand closing and opening
(Ieee, 2017)
Brain-computer interfaces allow people to manage electronic devices such as computers without using their motor nervous system. When the brain is in a function, nerve cells in the brain communicate with each other with ...
Geotechnical assessment of a slope stability problem in the Citlakkale residential area (Giresun, NE Turkey)
(Springer Heidelberg, 2017)
Because of the rapidly growing population, new settlement areas are required, and finding an appropriate location is always difficult, especially in mountainous areas. in these regions, efficient use of the existing ...
Graphene terahertz plasmons: A combined transmission spectroscopy and raman microscopy study
(Amer Chemical Soc, 2017)
Graphene provides a promising materials platform for fundamental studies and device applications in plasmonics. Here we investigate the excitation of THz plasmon polaritons in large-area graphene samples on standard oxidized ...
Geotechnical investigations and remediation design for failure of tunnel portal section: a case study in northern Turkey
(Science Press, 2017)
Mass movements are very common problems in the eastern Black Sea region of Turkey due to its climate conditions, geological, and geomorphological characteristics. High slope angle, weathering, dense rainfalls, and anthropogenic ...
The design steps of a hybrid energy system
(Polish Acad Sciences Inst Physics, 2017)
In this paper the design stages of a mixed photovoltaic-wind energy system, supplied with solar and wind energy was discussed. First, general information about the employed wind turbines and solar panels is given and their ...
Çoklu ardışık DFBÇ vericilerine ait belirsizlik fonksiyonunun pasif algılama uygulamaları için incelenmesi
(Ieee, 2017)
Passive radars are systems that do not have a transmitter of their own but can detect and track targets using "transmitters of opportinuity" in the environment. Particularly in recent years, the work in this area has gained ...
Investigation of GSM, LTE and Wi-Fi electromagnetic radiation in dwellings
(Polish Acad Sciences Inst Physics, 2017)
Electromagnetic radiation exposure increases with the rise of the wireless communication devices. Electromagnetic radiation, especially near 2400 MHz band, has gradually increased with the widespread of wireless fidelity ...
OFDM performance of ultra wideband in wireless body area network channel
(Polish Acad Sciences Inst Physics, 2017)
Data transfer for health monitoring can be highly critical because of life dependency transmitted data. IEEE 802.15.6 is a standard for wireless body area network published in 2012 to satisfy the reliability which is ...
Soft magnetic properties of HfxCo100-x thin films
(Springer, 2017)
HfxCo100-x thin films (in the atomic weight range of x = 30-36) were growth on Si (100) substrates by direct current (DC) magnetron sputtering method. Thin films produced with atomic compositions in this context depicted ...
