On a class of functional equations of the Wiener-Hopf type and their applications in n-part scattering problems
(Oxford Univ Press, 2003-12)
An asymptotic theory for the functional equation K-phi=f, where K : X-->Y stands for a matrix-valued linear operator of the form K=K1P1+K2P2+...+KnPn, is developed. Here X and Y refer to certain Hilbert spaces, {P-alpha} ...
Significance map pruning and other enhancements to SPIHT image coding algorithm
(Elsevier Science, 2003-10)
This paper proposes several enhancements to the Set Partitioning in Hierarchical Trees (SPIHT) image coding algorithm without changing the original algorithm's general skeleton. First and foremost, a method for significance ...
Joint channel tracking and symbol detection for OFDM systems with Kalman filtering
(Urban & Fischer Verlag, 2003)
This paper proposes a new joint channel tracking and symbol detection scheme for pilot symbol-assisted OFDM systems in multipath fading. The proposed scheme uses Kalman filters for both channel tracking and subsequent ...
Postprocessing of decoded color images by adaptive linear filtering
(Elsevier Science, 2003-02)
This paper presents an image adaptive linear filtering method for the reconstruction of the RGB (red, blue, green) color coordinates of a pixel from the lossy compressed luminance/chrominance color coordinates. In the ...
On the derivation of some non-linear evolution equations and their progressive wave solutions
(Pergamon-Elsevier Science, 2003-06)
In the present work, utilizing the reductive perturbation method, the non-linear equations of a prestressed viscoelastic thick tube filled with a viscous fluid are examined in the longwave approximation and some evolution ...
Amplitude modulation of nonlinear waves in a fluid-filled tapered elastic tube
(Wiley-V C H Verlag, 2003)
In the present work, treating the arteries as a tapered, thin walled, long, and circularly conical prestressed elastic tube and using the reductive perturbation method, we have studied the amplitude modulation of nonlinear ...
Amplitude modulation of nonlinear waves in fluid-filled tapered tubes
(Consultants Bureau, 2003-12)
We study the modulation of nonlinear waves in fluid-filled prestressed tapered tubes. For this, we obtain the nonlinear dynamical equations of motion of a prestressed tapered tube filled with an incompressible inviscid ...
Failure of an exchange-rate-based stabilization plan in Turkey
(M E Sharpe, 2003-02)
The Turkish exchange-rate-based stabilization plan adopted in 2000 has been a spectacular failure, lasting a mere fourteen months despite a relatively flexible peg regime and preannounced exit strategy. The final three ...
Volumetric ultrasound imaging using 2-D CMUT arrays
(IEEE-Inst Electrical Electronics Engineers Inc, 2003-11)
Recently, capacitive micromachined ultrasonic transducers (CMUTs) have emerged as a candidate to overcome the difficulties in the realization of 2-D arrays for real-time 3-D imaging. In this paper, we present the first ...
Analysis of self-noise in a clock recovery system with a high-order nonlinearity
(IEEE-INST Electrical Electronics Engineers Inc, 2003-11)
This correspondence presents a new technique to compute efficiently the spectra of the in-phase (I) and quadrature (Q) components as well as the cross-spectrum of the in-phase and quadrature (I-Q) components of self-noise ...
