Reflectance data model with mixed lumped and distributed elements for wireless communication systems
(IEEE, 2005)
In this paper, a new method is presented to model the given reflectance data obtained from a "passive one-port physical device", as a lossless two port consists of lumped and distributed elements. Basis of the new method ...
Forward-looking IVUS imaging using an annular-ring CMUT array
(IEEE, 2005)
A 64-element, 1.15mm diameter annular-ring CMUT array was characterized and used for forward-looking IVUS imaging tests. The array was manufactured using low temperature processes suitable for CMOS electronics integration ...
A lumped circuit model for the radiation impedance of a 2D CMUT array element
(IEEE, 2005)
Elements of a 2D array used for 3D acoustic imaging have dimensions smaller than half of the acoustic wavelength due to the Nyquist criteria for spatial sampling. Therefore, analyses involving circuit models for the array ...
A sequential Monte Carlo method for blind phase noise estimation and data detection
(IEEE, 2005)
In this paper, a computationally efficient algorithm is presented for blind phase noise estimation and data detection jointly, based on a sequential Monte Carlo method. The basic idea is to treat the transmitted symbols ...
A new coding method for speech and audio signals
(IEEE, 2005)
In this paper a new representation or modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={S R } and Envelope vector E={E K } Sets (PSEVS). ...
A miniature real-time volumetric ultrasound imaging system
(SPIE-Int Soc Optical Engineering, 2005)
Progress made in the development of a miniature real-time volumetric ultrasound imaging system is presented. This system is targeted for use in a 5-mm endoscopic channel and will provide real-time, 30-mm deep, volumetric ...
Predictive vector quantization of 3-D polygonal mesh geometry by representation of vertices in local coordinate systems
(IEEE, 2005)
A large family of lossy 3-D mesh geometry compression schemes operate by predicting the position of each vertex from the coded neighboring vertices and encoding the prediction error vectors. In this work, we first employ ...
Frequency selective fading channel estimation in OFDM systems using KL expansion
(IEEE, 2005)
This paper proposes a computationally efficient, linear minimum mean square error (MMSE) channel estimation algorithm based on KL series expansion for OFDM systems. Based on such expansion, no matrix inversion is required ...
Determination of pre-gelation and post-gelation activation energies during free radical crosslinking copolymerization
(Taylor & Francis Ltd, 2005)
Steady-state fluorescence (SSF) and dilatoraetric techniques were used to study the free-radical crosslinking copolymerization (FCC) of styrene (S) and divinylbenzene (DVB) in bulk. The gel points (t g) were recorded by ...
Optimal nonlinear control of two-link flexible arm with adaptive internal model
(2005)
The control of highly nonlinear multi-link flexible arms is subject to uncertainties caused by backlash, payload changes and external disturbances.Therefore, adaptive and robust control of multi-link flexible arms is a ...
