Mixed spectral AKNS hierarchy from linear isospectral problem and its exact solutions

Open Physics, 2015
In this paper, the AKNS isospectral problem and its corresponding time evolution are generalized by embedding three coefficient functions. Starting from the generalizedAKNS isospectral problem, a mixed spectralAKNS hierarchy with variable coefficients is

Two dimensional inverse scattering from buried magnetic anomalies

Annals of Geophysics, 2008
This paper deals with the problem of the electromagnetic linear inverse scattering from magnetic anomalies buried in a lossy half space, for a scalar and two dimensional case. First, the formulation of the exact model of the electromagnetic scattering is

Subspace-Based Localization and Inverse Scattering of Multiply Scattering Point Targets

EURASIP Journal on Advances in Signal Processing, 2007
The nonlinear inverse scattering problem of estimating the locations and scattering strengths or reflectivities of a number of small, point-like inhomogeneities (targets) to a known background medium from single-snapshot active wave sensor array data is ...

On an Inverse Scattering Problem for a Discontinuous Sturm-Liouville Equation with a Spectral Parameter in the Boundary Condition

Boundary Value Problems, 2010
An inverse scattering problem is considered for a discontinuous Sturm-Liouville equation on the half-line [0,∞) with a linear spectral parameter in the boundary condition.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
