Inverse Gaussian Autoregressive Models
Journal of Time Series Analysis, 1999A first‐order autoregressive process with one‐dimensional inverse Gaussian marginals is introduced. The innovation distributions are obtained in certain special cases. The unknown parameters are estimated using different methods and these estimators are shown to be consistent and asymptotically normal.

Recent advances in neural network‐based inverse modeling techniques for microwave applications
International journal of numerical modelling, 2020Inverse modeling of microwave components plays an important role in microwave design and diagnosis or tuning. Since the analytical function or formula of the inverse input‐output relationship does not exist and is difficult to obtain, artificial neural ...

IEEE Transactions on Electron Devices, 2001
A simple, implicit, relation for the inversion charge density in the channel of metal oxide semiconductor (MOS) transistors is presented. The relation is continuous and covers the whole operating range, from subthreshold to strong inversion. The derivative of the local inversion charge density with respect to the channel voltage is a simple expression ...

Quantification of rust penetration profile in reinforced concrete deduced by inverse modeling
, 2020Chloride-induced corrosion causes insidious deterioration in reinforced concrete structures. Conventional numerical models for corrosion expansion ignore the penetration of rust into concrete, leading to an overestimation of the rust expansion force in ...
