Monitoring of dynamical processes in PAAm-MWNTs composites by fluorescence method
(Taylor & Francis Ltd, 2012)
Polyacrylamide (PAAm)-multi walled carbon nanotube (MWNT) composites were prepared by free radical cross-linking copolymerization in water. Ammonium persulfate and NN'-methylenebis (acrylamide) (BIS) were used as a free ...
Leveraging saving-based algorithms by master-slave genetic algorithms
(Pergamon-Elsevier Science Ltd, 2011)
Saving-based algorithms are commonly used as inner mechanisms of efficient heuristic construction procedures. We present a general mechanism for enhancing the effectiveness of such heuristics based on a two-level genetic ...
A new energy paradigm for Turkey: A political risk-inclusive cost analysis for sustainable energy
(Elsevier Science, 2011)
Implementing sustainable development policies in order to achieve economic and social development while maintaining adequate environmental protection to minimize the damage inflicted by the constantly increasing world ...
An intelligent approach to machine tool selection through fuzzy analytic network process
(Springer, 2011)
In this study we utilize analytic network process (ANP) a more general form of AHP for justifying stand-alone machine tools out of available alternatives in market due to the fact that AHP cannot accommodate the variety ...
Energy needs for drying of PAAm- kappa C composites prepared with various kappa C contents
(European Polymer Federation, 2011)
Various polyacrylamide (PAAm) - Kappa Carrageenan (kappa C) composite gels were prepared from acrylamide (AAm) N N'- methylenebisacrylamide (BIS) and different kappa C contents by free radical crosslinking copolymerization ...
Characterization Of Mps Capped Cds Quantum Dots And Formation Self-Assembled Quantum Dots Thin Films On A Glass Substrate
(Natl Inst R&D Materials Physics, 2011)
Colloidal powdered and thin film forms of MPS capped CdS quantum dots have been produced by combination of colloidal chemistry and sol-gel method. Nanoparticles were self-assembled directly on a glass substrate using spin ...
The Role of Pyranine in Characterization of PAAm-kappa C Composites by Using Fluorescence Technique
(Springer/Plenum Publishers, 2011)
Polyacrylamide (PAAm) doped by kappa-carrageenan (kappa C) gels were prepared with various amounts of kappa C varying in the range between 0 wt.% and 3 wt.%. Steady-state fluorescence (SSF) technique was employed for ...
(3+3+2) warped-like product manifolds with Spin(7) holonomy
(Elsevier Science Bv, 2011)
We consider a generalization of eight-dimensional multiply warped product manifolds as a special warped product by allowing the fiber metric to be non-block diagonal. We define this special warped product as a (3 + 3 + 2) ...
A New Preconditioner Design Based on Spectral Division for Power Flow Analysis
(Praise Worthy Prize Srl, 2011)
Solution of large sparse linear systems is the most lime consuming part in many power system simulations. Direct solvers based on LU factorization although robust are known to have limited satiability on parallel platforms. ...
