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 ...
Combined radiofrequency modified maze and mitral valve procedure through a port access approach: early and mid-term results
(Oxford University Press, 2003)
Objective: The aim of this study was to assess the feasibility and effectiveness of irrigated radiofrequency (RF) modified Maze procedure through a port access approach during mitral valve surgery and evaluate early and ...
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 ...
Development of an enzyme immunoassay for the determination of testosterone
(Scientific Technical Research Council Turkey-Tubitak, 2003)
In this study a double antibody enzyme immunoassay for the direct determination of testosterone in plasma was developed. Testosterone 3-O-CMO was conjugated with horseradish peroxidase by the mixed anhydride method and the ...
Comparison of intraoperative transit-time flow measurement with early postoperative magnetic resonance flow mapping - in off-pump coronary artery surgery
(Texas Heart Inst., 2003)
The purpose of this prospective study was to evaluate graft patency of off-pump coronary artery surgery intraoperatively by transit-time flow measurement and to compare this technique with postoperative magnetic resonance ...
Influence of cardiovascular risk factors on the outcome of coronary artery bypass surgery
(Springer Verlag, 2003)
Purpose. To assess the impact of gender age and other cardiovascular risk factors on the outcomes of patients undergoing coronary artery bypass grafting (CABG). Methods. A total of 5 067 consecutive patients undergoing ...
