Twisted nanocolumns for LIBs via phi-sweep method in ion assisted e-beam deposition
(Elsevier Science Sa, 2018)
In this work, twisted nanostructured silicon-copper (with 19%at. copper) thin film is fabricated by glancing angle deposition phi-sweep process of ion beam assisted electron beam evaporation method. The thin film delivers ...
Joint phy/mac layer security design using arq with mrc and null-space independent papr-aware artificial noise in siso systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
Automatic-repeat-request (ARQ) as a MAC layer mechanism and artificial noise (AN) as a physical layer mechanism along with the help of maximal ratio combining (MRC), are jointly designed to achieve secrecy. Basically, a ...
OFDM with index modulation for asynchronous mMTC networks
(MDPI, 2018)
One of the critical missions for next-generation wireless communication systems is to fulfill the high demand for massive Machine-Type Communications (mMTC). In mMTC systems, a sporadic transmission is performed between ...
A speckle-enhanced prism spectrometer with high dynamic range
(IEEE Inst Electrical Electronics Engineers Inc, 2018)
We present a novel spectrometer device offering a wide wavelength range and high resolution. The device builds upon a conventional prism spectrometer; however, an additional scattering medium is introduced to generate a ...
Deep learning- and word embedding-based heterogeneous classifier ensembles for text classification
(Wiley-Hindawi, 2018)
The use of ensemble learning, deep learning, and effective document representation methods is currently some of the most common trends to improve the overall accuracy of a text classification/categorization system. Ensemble ...
Utilization of aerial heterogeneous cellular networks: Signal-to-interference ratio analysis
(Korean Institute of Communications and Information Sciences (K I C S), 2018)
As a component of future communication networks, aerial telecommunication platforms are a promising solution to meet surging traffic demands. These platforms can be used as aerial base stations (ABSs) to build an aerial ...
Complications of 2-level dynamic stabilization: A correlative clinical and radiological analysis at two-year follow-up on 103 patients
(Turkish Neurosurgical Society, 2018)
AIM: To investigate the postoperative complications, such as screw loosening, screw breakage and adjacent segment disease (ASD), in patients who underwent surgery with 2-level dynamic stabilization systems. MATERIAL and ...
Mutual coupling compensation in transmitting arrays of thin wire antennas
(Applied Computational Electromagnetics Society (ACES), 2018)
This paper presents a numerical technique for the compensation of mutual coupling in transmitting arrays of thin wire antennas. The Method of Moments is used to compute the scattering parameters of the array. Using these ...
Busy tone based coexistence algorithm for WRAN and WLAN systems in TV white space
(Institution of Engineering and Technology-IET, 2018)
TV White Space (TVWS) refers to frequency band reserved only for licensed terrestrial TV broadcasting and is opened to unlicensed use under regulatory conditions. While regulations protect licensed systems from interference, ...
Drought hazard, vulnerability, and risk assessment in Turkey
(Springer Heidelberg, 2018)
Drought has multiple impacts on socioeconomic sectors, and it is expected to increase in the coming years due to non-stationary nature of climate change and variability. Drought hazard and vulnerability are investigated ...
