Oxygen diffusion into polystyrene-bentonite films
(Elsevier, 2009)
A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films. The composite films were prepared from the mixture of surfactant-free pyrene ...
A Robust Localization Framework to Handle Noisy Measurements in Wireless Sensor Networks
(IEEE, 2009)
We construct a robust localization framework to handle noisy measurements in wireless sensor networks. Traditionally many approaches employ the distance information gathered from ranging devices of the sensor nodes to ...
In situ steady state fluorescence (SSF) technique to study drying of PAAm hydrogels made of various cross-linker contents
(Elsevier Science, 2009)
Drying experiments of polyacrylamide (PAAm) gels were performed using steady-state fluorescence (SSF) spectrometer. Pyranine (P) was introduced as a fluorescence probe and intensity of P from various crosslinker content ...
A Simple Iterative Equalizer for Space Time Coded Multiple Antenna Systems
(IEEE, 2009)
In this paperg a simple low complexity iterative receiver for spacetime coded zSTCg transmission is proposed and the pen formance over frequencyyselective fast and quasistatic fading channels is investigatedF Simulation ...
Cascaded Lossless Commensurate Line Synthesis
(IEEE, 2009)
In this paper a synthesis algorithm for cascaded lossless commensurate lines is summarized. The algorithm is based on transfer matrix factorization. Firstly the characteristic impedance of the extracted element is calculated ...
Biomarkers of Secondhand Smoke Exposure in Waterpipe Tobacco Venue Employees in Istanbul Moscow and Cairo
(Oxford University Press, 2018)
Background: Most smoke-free legislation to reduce secondhand smoke (SHS) exposure exempts waterpipe (hookah) smoking venues. Few studies have examined SHS exposure in waterpipe venues and their employees. Methods: We ...
Steady state fluorescence technique for studying phase transitions in PAAm-PNIPA mixture
(Taylor & Francis, 2009)
The steady state fluorescence (SSF) technique was used to study the sol-gel phase transition during free radical crosslinking copolymerisation of various amounts of acrylamide (AAm) and N-isopropylacrylamide (NIPA) mixtures. ...
Polymer-Ceramic Nanocomposites
(Spie-Int Soc Optical Engineering, 2009)
Steady state fluorescence (SSF) and photon transmission (PT) techniques were used for studying film formation from TiO2 and Al2O3 covered polystyrene (PS) latex particles. These films were annealed at elevated temperatures ...
The Politics of Documentary

Towards Faster Branch Outage Simulations Using Simulated Annealing and Parallel Programming
(IEEE, 2009)
Contingency studies such as branch outage and generator outage are among important studies of energy management centers operations. Branch outage modeling on the other hand is one of the basic steps of post-outage state ...
