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 ...
A simple neuro-Heuristic computational intelligence algorithm for thin film flow equation arising in physical models
(Ieee, 2017)
In this study, computational method are used for finding the approximation in the solution of thin film flow problem using stochastic solver like genetic algorithm (GA) and pattern search (PS). the mathematical model is ...
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 ...
Remote leak hole localization for underwater natural gas pipelines
(Ieee, 2017)
A vast amount of natural gas pipelines are installed underwater and they can be punctured because of various reasons such as corrosion and their increasing ages. in this study, nature of acoustic signals which are generated ...
A parametric study on exergetic performance of a YSZ electrolyte supported SOFC stack
(Inderscience Enterprises Ltd, 2017)
This paper presents a parametric study on the exergetic performance assessment of an electrolyte supported solid oxide fuel cell (SOFC) stack. Considering the operating and design parameters of yttria stabilised zirconia ...
Sualtı doğalgaz boru hatlarında uzaktan sızıntı algılama
(Ieee, 2017)
Undewater natural gas pipelines whose numbers and ages are increasing day by day can be punctured because of various reasons. in this study, nature of acoustic signals generated by leakages on pipelines is examined and a ...
Zihinsel aritmetik tabanlı EEG sinyallerinden öznitelik çıkartımı
(Ieee, 2017)
Analysis of mental arithmetic based electroencephalography (EEG) signal can be helpful for patients who have difficulty learning or understanding arithmetic or have autism spectrum disorders. It is difficult to separate ...
Ekvatoral elektrojetin çok katmanli iletişim kanalı olarak modellenmesi ve FM radyo sinyalleri üzerindeki etkilerinin incelenmesi
(Institute of Electrical and Electronics Engineers Inc., 2017)
Equatorial Electrojet is a narrow current stream flowing to the east during daytime hours in the low-latitude ionospheric E region. This current acts as a channel and can cause distortions in the signals used for passive ...
Beyin-bilgisayar arayüzü uygulamalarında etkin kanalların belirlenmesi
(Ieee, 2017)
Brain computer interface systems are modeled to facilitate lives of patients who have not a problem in their cognitive functions but also can not move their muscles. the performance of such systems highly depends on features ...
A novel efficient PV - battery powered LED lighting scheme
(Ieee, 2017)
This paper presents a novel fully controlled, flexible and self-adjusting LED lighting PV-Battery powered scheme using a pulse-width modulation (PWM) switching. This scheme is controlled a dual-loop error driven, time ...
