Monte Carlo Solutions for Blind Phase Noise Estimation
(Springer International Publishing Ag, 2009)
This paper investigates the use of Monte Carlo sampling methods for phase noise estimation on additive white Gaussian noise (AWGN) channels. The main contributions of the paper are (i) the development of a Monte Carlo ...
Phase Transitions in Pure and Hybrid Hydrogels: A Fluorescence Study
(Wiley, 2009)
Recent observations on phase transitions around the critical point showed that the critical exponents differed drastically from percolation results and classical results for pure hydrogel systems depending on monomer ...
Analytical Expense Management System
(IEEE, 2009)
Although the development of communication technologies (e.g: UMTS ADSL) allowed the elaboration of multiple users' web applications (e.g. information storage) there are still many improvements on many applications to be ...
Critical Exponents of Thermal Phase Transitions of kappa-Carrageenan in Various Salt Solutions
(Wiley-VCH Verlag GmbH, 2009)
The steady state fluorescence (SSF) technique was employed to study the phase transitions Of kappa-carrageenan in NaCl and KCl solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. Scattered ...

Oxygen Diffusion into Polymer-Clay Composite Films as a Function of Clay Content and Temperature
(Wiley-VCH Verlag GmbH, 2009)
A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films as a function of clay content and temperature. The composite films were prepared ...
Construction of Lossless Ladder Networks With Simple Lumped Elements Connected Via Commensurate Transmission Lines
(IEEE-INST Electrical Electronics Engineers Inc, 2009)
In this work an algorithm to design lossless ladder networks with simple lumped elements connected via commensurate transmission lines is proposed. After giving the algorithm a lumped-element low-pass Chebyshev filter was ...
Modeling the optical properties of WO(3) and WO(3)-SiO(2) thin films
(Elsevier Science Bv, 2008)
The optical properties and surface morphology of sol-gel spin coated WO(3) and WO(3)-SiO(2) composite films annealed at 250 and 400 degrees C are investigated. For the purpose of extracting the optical parameters of the ...
Electrochromic properties of heat-treated thin films of CeO2-TiO2-ZrO2 prepared by sol-gel route
(Elsevier Science Bv, 2008)
CeO2-TiO2-ZrO2 thin films were prepared using the sol-gel process and deposited on glass and ITO-coated glass substrates via dipcoating technique. The samples were heat treated between 100 and 500 degrees C. The heat ...
Performance of transmit and receive antenna selection in the presence of channel estimation errors
(IEEE-INST Electrical Electronics Engineers Inc, 2008)
This letter considers the effect of channel estimation errors on the performance of space-time coded (STC) systems with transmit and receive antenna selection over quasi-static flat fading channels. By performing pairwise ...
