  • Application of Single Objective Genetic Algorithm to Optimize Heat Transfer Enhancement from a Flat Plate 

    Javadi, Seyed Mohammad؛ Haghparast, Payam؛ Kahrom, Mohsen (Materials and Energy Research Center, 2012-03-01)
    The optimal shape of a two dimensional turbulator above an isothermal flat plate is found by using numerical simulation. The turbulent boundary layer over the flat plate was disrupted at various situations by inserting a ...

  • Prediction of Work Roll Initial Crown according to Desired Strip Profile in Hot Rolling 

    Samareh salavati pour, Hadi؛ Khademhosseini Beheshti, Hamid؛ Poursina, Mehrdad (Materials and Energy Research Center, 2012-03-01)
    The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed ...

  • The optimal energy carriers substitutes in thermal power plants:A fuzzy linear programming model 

    Kianfar, F.؛ Razzaghi, Talayeh (Materials and Energy Research Center, 2012-03-01)
    In this paper, a dynamic optimization approach for optimal choice of energy carriers in thermal power plants is proposed that analyzes the substitution of energy carriers in short-term planning of a power plant.The model ...

  • A New Acceptance Sampling Design Using Bayesian Modeling and Backwards Induction 

    Niaki, S.T.A.؛ Fallah Nezhad, Mohammad Saber؛ Vahdat Zad, Mohammad Ali (Materials and Energy Research Center, 2012-03-01)
    In acceptance sampling plans, the decisions on either accepting or rejecting a specific batch is still a challenging problem. In order to provide a desired level of protection for customers as well as manufacturers, in ...

  • Moving Load Analysis of Submerged Floating Tunnels 

    Mirzapour, Jamil؛ Shahmardani, Mahdieh؛ tariverdilo, saeed؛ Gheyretmand, Changiz (Materials and Energy Research Center, 2012-03-01)
    The concept of floating submerged tunnels becomes increasingly attractive idea to cross the straits. The structural solution in these bridges includes buoyancy force on tunnel body plus tension in mooring tethers. This ...

  • THEORETICAL AND NUMERICAL STUDY ON THE STRENGTHENED STEEL PLATE SHEAR WALLS BY FRP LAMINATES 

    Nateghi, F.؛ Khazaei-Poul, Masoud (Materials and Energy Research Center, 2012-03-01)
    In this paper, nonlinear behavior of strengthened steel plate shear walls (SPSWs) by FRP laminates theoretically and numerically has been investigated. In the first part, a new method, “the composite-plate frame Interaction ...

  • Effect of collar on time development and extent of scour hole around cylindrical bridge piers 

    Karimaee Tabarestani, Mojtaba؛ Zarrati, A.R. (Materials and Energy Research Center, 2012-03-01)
    An experimental approach was carried out to study the time development and extension of scouring around a circular pier protected by a collar. The experiments included the study of scouring around an unprotected pier as ...

  • Optimization of Lipase Immobilization 

    Alemzadeh, Iran؛ Sayyar Kavardi, Seyyedeh Sepideh؛ Kazemi, A. (Materials and Energy Research Center, 2012-03-01)
    Pseudomonas aeruginosa BBRC-10036 was used for lipase production. The organism secreted the enzyme extracellulary. In order to purify the enzyme, precipitation was done first, and then this lipase has been purified by Ion ...
