Inverse Simulation for Hypersonic Vehicle Analysis
19th AIAA International Space Planes and Hypersonic Systems and Technologies Conference, 2014This paper presents the development of an inverse simulation method for hypersonic vehicles and uses the method for design evaluation and trajectory analysis. Inverse simulation is a technique in which the control inputs, required to achieve a desired system output are computed through inversion of the system equations.

Resolution Analysis in Full Waveform Inversion
Geophysical Journal International, 2011We propose a new method for the quantitative resolution analysis in full seismic waveform inversion that overcomes the limitations of classical synthetic inversions while being computationally more efficient and applicable to any misfit measure. The method rests on (1) the local quadratic approximation of the misfit functional in the vicinity of an ...

Sensitivity analysis of lidar inversion algorithms
Applied Optics, 1986The lidar inversion algorithms based on near-end and far-end boundary conditions are reviewed and the recently proposed algorithm featuring the calculation of the boundary value at some middle range is expressed in analytic form. A theoretical assessment of the stability of all three algorithms to uncertainties in the boundary value and assumed ...

Inverse Analysis: Introduction
2011Numerical simulations have been established as a powerful tool used in practically all fields of engineering and science. A large number of commercial codes is developed to solve the, so-called direct problems (or forward problems), which consist of finding the solution in terms of response fields when a complete set of input data defining uniquely the

INVERSE SIMULATION FOR NONLINEAR SYSTEM ANALYSIS
IFAC Proceedings Volumes, 1987Abstract A heuristic analysis tool for nonlinear dynamical systems is described, which is based on the solution of a sequence of optimal control problems. These are solved by a direct shooting method, which uses information of system simulation to update the control parameters into a desired direction.

Impact of Measurement Errors in Inverse Analysis
2017During the first step in the development of any structural system identification method, the method should be validated by noise-free measurements in the first place. Nevertheless, this assumption is far from reality as the measurements in these tests are always subjected to the errors of measurement devices.
