Design of distributed-element RF filters via reflectance data modeling
(Elsevier GMBH Urban & Fischer Verlag, 2008)
A reflectance-based modeling method is presented to obtain the distributed-element counterpart of a lumped-element network which is described by measured or computed reflectance data at a set of frequencies. Numerical ...
Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008)
In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ...
Design of broadband microwave amplifiers with mixed-elements via reflectance data modeling
(Elsevier GMBH Urban & Fischer Verlag, 2008)
A practical method is introduced to design single-stage broadband microwave amplifiers with mixed lumped and distributed elements via modeling the reflectance data obtained from lumped-element input and output matching ...
Modeling based real frequency technique
(Elsevier GMBH Urban & Fischer Verlag, 2008)
Usually commercially available software tools are used to design matching networks for wireless communication systems. But a properly selected matching network topology with good initial element values must be supplied to ...
Explicit synthesis formulae for cascaded lossless commensurate lines
(Fachverlag Schiele Schon, 2008)
In literature synthesis of cascaded lossless commensurate lines have been realized via some iterative methods. So to be able to obtain the value of an element which is not the first one the designer has to obtain all the ...
Selective liquid-liquid extraction of mercuric ions by octyl methane sulfonamide
(Marcel Dekker Inc, 2003)
N-octyl methane sulfonamide (OMSA) has been demonstrated to be a very efficient reagent for selective extraction of Hg(II) ions from aqueous solutions. The extraction bases on rapid reaction of OMSA with Hg(II) ions yielding ...
Relay-Aided Secure Broadcasting for VLC
(IEEE, 2018)
A visible light communication (VLC) broadcast channel is considered in which a transmitter communicates with two receivers in the presence of an external eavesdropper. Trusted cooperative half-duplex relays are deployed ...
Ethnic fractionalization conflict and educational development in Turkey
(Pergamon-Elsevier Science Ltd, 2019)
We examine the impact of ethnic fractionalization and conflict on limiting the educational development in Southeastern Turkey. Our estimates show that although the armed conflict in the region did not directly hinder ...
Neo-developmentalist turn in the global political economy? The Turkish case
(Routledge Journals Taylor & Francis Ltd, 2018)
The 2008 global economic crisis galvanized the debate on neo-developmentalism as the pendulum of economic thinking began to swing away from neoliberalism. The current shift in the modalities of market governance mainly ...
Non-preemptive priority scheduler with multiple thresholds for network routers
(Pamukkale Univ, 2018)
The vast variety of applications available and being developed for computer networks have different quality of service requirements. One of the most significant ways to satisfy the needs of the applications is the packet ...
