Abstract The present paper introduces a Legendre polynomials based interval inversion method for processing multi-borehole logging data. allows the determination of lateral changes layer-thicknesses together with vertical and variations petrophysical parameters along 2D cross-section several boreholes. is assessed using noisy synthetic measurements model made two-layers structure related to hyd...

Damage detection of civil and mechanical structures based on measured modal parameters using model updating schemes has received increasing attention in recent years. In this study, for uncertainty-oriented damage identification, a non-probabilistic structural identification (NSDI) technique an optimization algorithm interval mathematics is proposed. order to take into account the uncertainty q...
