this paper presents an overview of model updating and particularly its application for updating of frame model. in this article a mathematical model of the frame was produced with finite element method. the frame was subjected to hammer modal testing. then the results of the modal testing were compared with those predicted with the model. this comparison revealed discrepancies between these two...

in this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3he atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. to perform the calculations, we have considered the kinetic term, and coulomb interaction between the particles in our hamiltonian. the calculated properties are free ener...

the computational method based on using the operational matrix of anorthogonal function for solving variational problems is computeroriented. in this approach, a truncated hartley series together withthe operational matrix of integration and integration of the crossproduct of two cas vectors are used for finding the solution ofvariational problems. two illustrative examples are included todemon...
