Power and rate adaptation for MQAM/OFDM systems under fast fading channels
(IEEE, 2012)
In this paper the effect of power and rate adaptation on the spectral efficiency of orthogonal frequency division multiplexing (OFDM) systems using M-ary quadrature amplitude modulation (MQAM) is investigated in the presence ...
Product ımprovement with Quality Function Deployment (QFD) technique
(Trans Tech Publications Ltd, 2012)
The purpose of this paper is to improve a new part for the natural gas sector using Quality Function Deployment (QFD) technique. QFD methodology was chosen for the product improvement process at IGDAS (Istanbul natural gas ...
OFDM with transmit and receive antenna selection based on subcarrier groups
(IEEE, 2012)
In this paper the performance of coded OFDM transmission over multiple antennas is explored when joint transmit and receive antenna selection is employed. The channel is assumed as Rayleigh frequency selective fading channel ...
A Novel Image Steganography Technique based on Similarity of Bits Pairs
(IEEE, 2017)
Steganography is one of the most important information hiding mechanism which can be used along with cryptography for providing adequate data security. The common Steganographic mediums used are text image audio and video ...
Reduction of energy costs and traffic flow rate in urban logistics process
(Elsevier Science, 2017)
Energy cost is a phenomenon relating to logistics and transportation activities of logistics operators as well as governments local authorities and citizens. Actually all the logistics parties may be affected by energy ...
Beacons for Indoor Positioning
(IEEE, 2017)
This work aims to develop a system for the tracking and control of elderly or handicapped people in an indoor environment. We have developed both a special box using an Arduino board and a mobile application on Android to ...
Experimental experience in design education as a resource for innovative thinking: The case of Bruno Munari
(Elsevier Science Bv, 2010)
Design education in general includes various design fields such as product design graphic design communication design and design in engineering. Designing as an activity captures all these various fields. Design refers ...
Visual culture in art teacher education: A Turkish case
(Elsevier Science Bv, 2010)
As globalization impacts Turkish culture the training and preparation of art teachers is increasingly important because these individuals will play a key role in teaching children how to become visually literate in a quickly ...
On-Line Transient Stability Assessment Using Matlab Parallel Programming Environment
(IEEE, 2010)
Transient Stability Assessment (TSA) is the major part of Dynamic Security Assessment (DSA) in an electric power system. On-line TSA has gained more importance for power system security in last two decades. The decreasing ...
Parallel Implementation Of Iterative Rational Krylov Methods For Model Order Reduction
(IEEE, 2010)
Model order reduction (MOR) techniques are getting more important in large scale computational tasks like large scale electronic circuit simulations. In this paper we present some experimental work on multiprocessor systems ...
