Sparsity Preserving Computation for Spectral Projectors
(Amer Inst Physics, 2011)
Several areas of applications such as model order reduction preconditioner design and eigenvalue problems for spectral projectors can be found in the literature. In this paper a fast and sparsity preserving approach for ...
Modelling of Swelling by the Fluorescence Technique in Kappa Carrageenan Gels
(Amer Inst Physics, 2011)
Kappa (-kappa) carrageenan gels prepared with various carrageenan concentrations in pure water were completely dried and then swelled in water vapor. Steady state fluorescence measurements were performed using a spectrometer ...
An energy efficient routing algorithm (X-Centric routing) for sensor networks
(INT INST Informatics & Systemics, 2011)
Recent developments in wireless communications and electronics technologies have enabled the progress in low cost sensor networks. Sensor networks differ from traditional networks in several ways such as the severe energy ...
Bayesian compressive sensing for ultra-wideband channel models
(IEEE, 2012)
Considering the sparse structure of ultra-wideband (UWB) channels compressive sensing (CS) is suitable for UWB channel estimation. Among various implementations of CS the inclusion of Bayesian framework has shown potential ...
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 ...
Space-Time Block Coding for Spatial Modulation
(IEEE, 2010)
Space-time block coded spatial modulation (STBC-SM) which employs space-time block coding (STBC) for spatial modulation (SM) is proposed as a new multiple-input multiple-output (MIMO) transmission scheme. In the STBC-SM ...
Joint Channel Estimation and Equalization for OFDM based Broadband Communications in Rapidly Varying Mobile Channels
(IEEE, 2010)
This paper is concerned with the challenging and timely problem of channel estimation for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying ...
Mobile Application Development for the Estimation of Recurrence in Post-Operative Kidney Cancer Cases
(IEEE, 2018)
In this paper a post-operative recurrence estimation tool called Sorbellini's nomogram for the kidney cancer patients showing no metastates is introduced and a novel application for mobile devices based on this model is ...
