Detection of jointly active primary systems
(IEEE, 2012)
Recent studies in cognitive radios consider the detection of multiple bands for a better utilization of the spectrum. If the cognitive radio (CR) is an ultra wideband (UWB) or a wideband system then the CR should ensure ...
Detection of Trojans in integrated circuits
(IEEE, 2012)
This paper presents several signal processing approaches in Trojan detection problem in very large scale integrated circuits. Specifically wavelet transforms spectrograms and neural networks are used to analyze power ...
Connected navigation of non-communicating mobile agents
(IEEE, 2012)
This article discusses the connectivity of autonomous mobile robots that do not have communication capabilities. We show that if the group members follow the proposed Local Steering Strategy which utilizes information only ...
Fuzzy logic for decision extraction from product reviews
(Institute of Electrical and Electronics Engineers Inc., 2018)
Most of manufacturers and merchants sell their products via internet websites where customers buy them and write their reviews regarding the purchased product. These reviews carry a lot of information. Prospective customers ...
Why do students prefer search engines over academic databases
(IEEE Computer Society, 2013)
Students' preference of search engines in online information retrieval has been a problem for several reasons. This work tries to share our experience about the reasons why they do not utilize academic databases. Past ...
Effects of channel models and optional data rates on the IEEE 802.15.4a system performance [Kanal modellerinin ve seçime bağli veri hızlarının IEEE 802.15.4a sistem başarımına etkileri]
(2010)
The wireless personal area network standard IEEE 802.15.4a uses ultra wideband impulse radios (UWB-IRs) for precise ranging and location and as well as for communications at low data rates (about 1 Mb/s). In addition to ...
Semiblind joint channel estimation and equalization for OFDM systems in rapidly varying channels
(2010)
We describe a new joint iterative channel estimation and equalization algorithm for joint channel estimation and data detection for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency ...
Post-outage state estimations for outage management
(IFAC Secretariat, 2011)
Real time outage information is required to the utility operators for outage management process. In addition to some basic information regarding the outage post-outage system status will help to improve the response to ...
Electromagnetic interactions of heavy ions at small impact parameters and lepton pair productions
(Institute of Physics Publishing, 2011)
In peripheral collisions the strong electromagnetic fields are produced since the fully stripped heavy ions moves at ultra-relativistic velocities. Lepton pairs especially the electron-positron pairs are the result of this ...
Digital crime and punishment: Turkish online journalism under siege
(International Institute of Informatics and Systemics IIIS, 2012)
Turkish mass media since its beginnings in late 19th century has aimed to gain its role as the fourth estate in Turkish political scene. The freedom of press has been at the paramount of discussions since the foundation ...
