We develop a ``hybrid'' model of the proton inelastic structure functions applicable in wide region invariant mass produced states $W$ and momentum transfer $Q$ including deep scattering (DIS), nucleon resonance production, as well close to threshold. DIS is described terms parton distributions together with higher-twist corrections from an available global QCD fit. The resonant part addressed ...

This paper presents an efficient method for updating the structural finite element model. Model updating is performed through minimizing the difference of recorded acceleration of real damaged structure and hypothetical damaged structure, by updating physical parameters in each phase using iterative process of Levenberg-Marquardt algorithm. This algorithm is based on sensitivity analysis and pr...
