Channel adaptive encoding and decoding strategies and rate regions for the three user cooperative multiple access channel
(IEEE, 2008)
For a cooperative Gaussian multiple access channel (MAC), we propose a new channel adaptive three user cooperation strategy, based on a non-trivial extension of block Markov super-position encoding. We obtain the expressions ...
In situ fluorescence study of swelling, sorption and desorption processes in and out of PAAm gels
(Wiley-V C H Verlag GMBH, 2008-05)
Small molecule sorption and desorption in and out of polyacrylamide (PAAm) gels were studied at various temperatures. Pyranine (P(y)) dissolved in water used as a probe. Fluorescence emission intensity, I(p) from P(y) was ...
Temperature effect on drying and swelling of kappa carrageenan gels: A steady state fluorescence study
(Wiley-V C H Verlag GMBH, 2008)
A novel technique based on in situ steady state fluorescence (SSF) measurements is introduced for studying drying and swelling Of kappa(-) carrageenan (kappa carrageenan) gels at various temperatures. kappa(-) carrageenan ...
Fast inter-mode decision and selective quarter-pel refinement in H.264 video coding
(IEEE, 2008)
In H.264 video coding standard, there exist several inter - prediction modes that use macroblock partitions with variable block sizes. Choosing a rate-distortion optimal coding mode for each macroblock is essential for the ...
3-D Vibration analysis of the rectangular micro damaged plates
(Springer, 2008)
In the present work, damaged plates are modeled by the micro-elongation theory which neglects the micropolar effects in Eringen's microstretch theory. The wave propagation problem is Studied and a new wave which does not ...
Travelling waves in a prestressed elastic tube filled with a fluid of variable viscosity
(Springer, 2008)
In this work, treating the artery as a prestressed thin elastic tube with variable radius and the blood as all incompressible Newtonian fluid with variable viscosity, the propagation of nonlinear waves ill Such a composite ...
A cost-efficient bit-serial architecture for sub-pixel motion estimation of H.264/AVC
(IEEE Computer Soc, 2008)
This paper presents a new VLSI architecture for sub-pixel motion estimation in H.264/AVC encoder. It is based on an interpolation free algorithm that causes a high level reduction on memory requirement, hardware resources ...
Damar içi öne bakan ultrasonik görüntüleme için eşdeğer dizi örnekleme yöntemleri
(IEEE, 2009-06-26)
Damar içi öne bakan ultrasonik görüntüleme gerçek zamanlı hacimsel (üç boyutlu) görüntülemeye imkan vermesi bakımından yaygın olarak kullanılmaktadır. Damar içi görüntülemede fiziksel boyutların küçük olması nedeniyle ...
Cryptanalysis of image encryption with compound chaotic sequence
(IEEE, 2009)
Recently, an image encryption algorithm based on compound chaotic sequence was proposed [Tong et al., Image and Vision Computing 26 (2008) 843]. In this paper, we analyze the security weaknesses of the proposal. We give ...
Damariçi yanal kesit görüntüleme için farklı prob yapılarının incelenmesi
(IEEE, 2009-06-26)
Bu çalışmada dönen bir şaftın yanal yüzeyine yerleştirilmiş 8 adet içiçe halka elemanlardan oluşan yana bakan görüntüleme için yeni bir kateter yapısı incelenmiştir. Bu Katater mimarisi basit bir dizi önü alıcı verici ...
