Slow release of trapped homopolymers from a swelling polymeric gel: A fluorescence study
(Taylor & Francis Inc, 2008)
In-situ steady-state fluorescence experiments were performed for studying slow release of pyrene-labeled polystyrene chains from polystyrene gels formed by free-radical crosslinking copolymerization. Atom transfer radical ...
Broadband Decoupling and Matching of a Superdirective Two-Port Antenna Array
(IEEE-INST Electrical Electronics Engineers Inc, 2008)
Decoupling and matching networks may be used to improve the performance of compact antenna arrays where mutual radiator coupling has caused a degradation of the diversity capabilities. A popular network consists of a 180 ...
Influence of pH on the optical and structural properties of spin coated CeO2-TiO2 thin films prepared by sol-gel process
(Elsevier Science Bv, 2007)
Optical and structural properties of mixed CeO2-TiO2 thin films have been investigated by varying the pH of the coating sol. The films were prepared by sol-gel process using spin-coating technique with a spin speed of 2500 ...
Synthesis of cascaded lossless commensurate lines
(IEEE-INST Electrical Electronics Engineers Inc, 2008)
A scattering transfer matrix factorization based algorithm for cascaded lossless commensurate line synthesis is presented. The characteristic impedances of the extracted commensurate lines and the reflection factors of the ...
An intelligent approach to ERP software selection through fuzzy ANP
(Taylor & Francis, 2007)
During the implementations of enterprise resource planning (ERP) systems most companies have experienced some problems one of which is how to determine the best ERP software satisfying their needs and expectations. Because ...
A hybrid approach to machine-tool selection through AHP and simulation
(Taylor & Francis, 2007)
The selection process of a machine tool has been a critical issue for companies for years because the improper selection of a machine tool might cause many problems having a negative effect on productivity precision ...
Blind-phase noise estimation in OFDM systems by sequential Monte Carlo method
(John Wiley and Sons Ltd, 2006)
One of the main drawbacks of orthogonal frequency division multiplexing (OFDM) systems is the phase noise (PN) caused by the oscillator instabilities. Unfortunately due to the PN the most valuable feature namely orthogonality ...
Atomic force microscopy and spectroscopy studies of annealed Ce/Ti/Zr mixed oxide thin films prepared by sol-gel process
(Elsevier Science Bv, 2006)
Mixed Ce/Ti/Zr oxide thin films with a molar ratio of 0.5:0.25:0.25 were prepared using the sol-gel process and deposited on glass substrates by the dip coating technique. The effect of heat treatment temperature on surface ...
A combined fuzzy AHP-goal programming approach to assembly-line selection
(IOS Press, 2007)
In mass production assembly-line balancing (ALB) problem has been a critical and repetitive issue for companies for long time. On the other hand equipment selection for stations has also been another important problem at ...
Prevention of complications in laparoscopic hysterectomy: Experience with 1120 cases performed by a single surgeon
(Elsevier Science, 2007)
STUDY OBJECTIVE: The aim of this study is to describe a safe technique without any ureteral DESIGN: Prospective study (Canadian Task Force classification II-3). SETTING: Centre Hospitalier Interregional Edith Cavell ...
