Multi-parameter inverse analysis research based on Comsol Multiphysics and Matlab

2010 International Conference On Computer Design and Applications, 2010
This paper constructs a parameter inverse analysis model for the diffusion analysis experiments of multi-ion transport model. It transforms multi-parameter inverse analysis problem into an optimization problem for nonlinear constrained planning. The optimization principle, the sequential quadratic programming method (SQP) for optimization and its ...

Multi-Parameter Inversion and Thermo-Mechanical Deformation Decoupling using I-DIC

Experimental Mechanics, 2016
The simultaneous and accurate identification of multiple thermo-mechanical parameters of superalloy materials in complicated service condition is an important and difficult problem. In this paper, an integrated digital image correlation (I-DIC) method was developed to address this issue.

POCS-based geophysical constraints in multi-parameter Full Wavefield Inversion

Proceedings, 2013
Simultaneous updating of several parameters in Full Wavefield Inversion (FWI) can lead to poor convergence and unsatisfactory results due to cross-talk among various inversion parameters. Even more dangerously, certain parameter combinations may correspond to physically unrealizable models, leading to instabilities in forward simulations. Both types of

Inversion for Multi-Parameter Depth-Profiles: Thermal Conductivity and Thermal Impedance

1999
Recently, the depth profile reconstruction of the thermal conductivity or diffusivity of inhomogeneous samples has attracted considerable interest [1–4]. But in most of these works, a mathematical model for unknown profiles was a prior assumed, then some parameters were adjusted to fit the measured data.

RNN-Based Full Waveform Inversion for Robust Multi-Parameter Bone Quantitative Imaging

Computer Methods and Programs in Biomedicine
The full waveform inversion (FWI) method plays a significant role in bone quantitative imaging. It is shown that even a small deviation in transducer positions can lead to a considerable variation in frequency-domain signals, and result in a marked decline in the performance of frequency-domain full waveform inversion (FDFWI).
