Space time coded OFDM system with transmit and receive antenna selection
(2010)
In this paper antenna selection both at the transmitter and the receiver is proposed for space-time coded (STC) orthogonal frequency division multiplexing (OFDM) systems. Antennas for all-subcarriers or per-subcarrier are ...
A low-complexity KL expansion-based channel estimator for OFDM systems
(2005)
This paper first proposes a computationally efficient pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach employs ...
Programmed cell death in heart failure: Review [Programlı hücre ölümünün kalp yetersizli?indeki yeri]
(2005)
The molecular and biochemical mechanisms of programmed cell death also known as apoptosis have not yet to be fully elucidated. Apoptosis is characterized by active intracellular communication loss of cellular attachment ...
Fault tolerant control with re-configuring sliding-mode schemes
(2005)
In this paper a controller design method for linear MIMO systems is presented which a sliding mode controller is reconfigured in case of system faults. Faults are detected with the residual vector generated from a standard ...
Effect of glurenorm on immunohistochemical changes in pancreatic ? cells of rats in experimental diabetes
(2005)
Immunohistochemical localization of islets of Langerhans of streptozotocin (65 mg/kg ip) induced diabetic + glurenorm (10 mg/kg po) treated female albino rats revealed increase in number of ? cells and insulin immunoreactivity ...

(Emerald Group Publishing Limited, 2012)
Purpose - The purpose of this paper is to identify the B2B e-commerce (B2BEC) usage patterns of North American small- and medium-sized enterprises (SMEs) in their supply chains the contextual factors that influence usage ...
Assessing quality in higher education: New criteria for evaluating students' satisfaction
(Taylor & Francis, 2011)
The aim of this research is to present a new quality assurance model (5Qs) and to examine the major factors affecting students' perception of cumulative satisfaction. The model includes behavioural dimensions of student ...
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 ...
