The standard Arrehenious equation of 0.3% carbon steel is utilized to obtain an optimal deformation path such that the percentage of volume fraction recrystallization should be 1. Xia,"Microstructure and property of a medium carbon steel processed by equal channel angular pressing", materials forum volume 32 –2008, Edited by J. The presence of zone of inhibition clearly indicated the antibacterial activity of silver nanoparticles.
This approach is applied to obtain the desired percentage of volume fraction recrystallization of '1' from an initial value of '0'. Antibacterial assay of synthesized Ag NP was carried out in solid (Nutrient Agar) growth medium against J., Interaction of silver nanoparticles with biological surfaces of Caenorhabditis elegans.

'Investigation and Improvement of Ejector Refrigeration System Using Computational Fluid Dynamics Technique' Energy Conversion and Management 2007; 56–64. Experimental investigation of a novel steam ejector refrigerator suitable for solar energy applications. In this Paper, a new approach for controlling microstructure development during hot working process by percentage of volume fraction recrystallization is proposed. One of the approaches is based on the Optimal Control theory and involves the developing of state space models to describe the material behavior and the mechanics of the process. The elemental composition of synthesized sample was confirmed by EDS analysis.

Applied Thermal Engineering 2008; 7–77Abstract: The strength of any material is dependent on the grain size and percentage of volume fraction recrystallization. Wuhrer© Institute of Materials Engineering Australasia Ltd. Venugopalet.a.l, "Optimization of Microstructure during Deformation Processing Using Control Theory Principles", Scripta Materialia, vol. The DLS analysis showed the particle distribution of synthesized silver nanoparticles in solution, and SEM analysis showed the morphology of nanoparticles.
The values for linear shrinkage, permeability to air and thermal shock averaged 8.57% 69.4, and 29 respectively and these also were within the accepted limits.

Solid density averaged 3.18g/cm3 with 0% saw dust and 2.91g/cm 3 with 40% saw dust, still bringing them closer to the international range of 2.3-3.5g/cm3 . The simulation is done on various values for percentage of volume fraction recrystallization using both the controllers by MATLAB simulink toolbox.  James C ,"Optimization of microstructure development during hot working using control theory,"Metullurgical and Materials Transactions A, Vol 28 A, pp.1921-1930, Sep 1997.
The results showed that the linear shrinkage improved from an average of 8.57% for the three samples for 0% sawdust to an average of 8.32% with 40% addition of saw dust, bringing them closer to the lower range of the international standard of 7-10%. In the other approach PID controller is employed for the plant model (microstructure development).
