The merging of optimization and simulation technologies has seen a remarkable growth in recent years. A Google search on “Simulation Optimization” returns more than one hundred and thirty thousand pages where this phrase appears. The content of these pages ranges from articles, conference presentations and books to software, sponsored work and consultancy. This is an area that has sparked as mu...

The growth of Internet and web is changing the life style of current generation. In its result, heterogeneous data is available on the web and to retrieve integrated data is a challenge for the researchers and developers. Query optimization techniques are used for information retrieval. In this paper, web centric classical queries processing and optimization techniques, classification of the di...

Optimization of a fixed-bed bioreactor used in wastewater treatment is addressed. The objective of optimization is to maximize the treatment efficiency of the biofilter by manipulating the feed flow rate while satisfying operational constraints. Numerical results indicate that the optimal input is characterized as being on the boundary of the admissible region. Thus, the characterized optimal s...

In this study, the effects of some factors on bacterial growth and ferrous oxidation rates were investigated by Acidithiobacillus ferrooxidan in 250 ml shake flasks. One factor at a time (OFAT) design approach was used for preliminary evaluation of various factors affecting the process, such as pH, initial ferrous and elemental sulfur concentrations, shaker agitation rate, and liquid to flask v...

In our information age, information alone has become a driver of social growth. Information is the fuel of “big data” companies, and the decision-making compass of policy makers. Can we quantify how much information leads to how much social growth potential? Information theory is used to show that information (in bits) is effectively a quantifiable ingredient of growth. The article presents a s...

What is the optimal operation of metabolic networks? This question is interesting to answer, as it would provide information on which underlying principles have shaped metabolic networks during evolution, and it may allow us to identify some simple rules governing the operation of metabolic networks under different growth conditions. Such rules might be important for metabolic network engineeri...
