Numerische Systeminversion (Numerical System Inversion)
auto, 2000Ein Teilproblem bei Trajektorienfolgeregelungen ist die Berechnung eines Eingangssignals für ein gewünschtes Ausgangsverhalten. Bei nichtlinearen Prozessmodellen ist diese Aufgaben-stellung oft nur mit sehr hohem Aufwand oder nur in grober Näherung lösbar. In diesem Beitrag wird ein effizientes Verfahren zur Systeminversion vorgestellt, welches auf dem

Numerical inversion of discontinuous conductivities
Inverse Problems, 2000Summary: An inverse problem is considered to identify the geometry of discontinuities in a conductive material \(\Omega\subset \mathbb{R}^2\) with conductivity \(1+ (k-1)\chi_D\) frm the measurements taken on the boundary \(\partial\Omega\), where \(D\Subset \Omega\) and \(k\) is a known positive constant.

Numerical Case Studies: Inverse Problems
2019Optimization plays a key role in the design of any device or system, and this is especially true for MEMSs. The issue is to find a design space for a device which will satisfy the performance specifications. Often, they include several design criteria which cannot all be met at the same time. This leads to the concept of multi-objective optimization, i.

Numerical inverse computation of reflectivity
High Power Laser and Particle Beams, 2013By analyzing the one-dimensional heat transfer equation under the heat flux boundary condition, a numerical method for inverse computation from the back surface temperature data to the front surface reflectivity data is proposed. The inversely computing program is verified by the positive and inverse computation of one-dimensional heat transfer.

Numerical inversion of Laplace transform
Calcolo, 1967The paper describes a general method for the numerical calculation of Laplace's inverse transform of a given function. The general method is then specialized to two cases in which the computer is shown to be of great use. An appendix contains the solution of the collateral problem of the numerical derivation of a function.

Numerical Laplace Transformation and Inversion
International Journal of Electrical Engineering & Education, 1978The paper presents an efficient basis for the numerical manipulation of the Laplace transform for the purpose of solving transient problems which are not amenable to conventional analytic manipulation. Although the underlying material is not new, the manner of presentation is such as to expose important matters of detail.

NUMERICAL INVERSION OF AXISYMMETRIC INTERFEROGRAMS
Experimental Heat Transfer, 1996A new method is presented for inverting the integrated phase-shift data obtained from an axisymmetric refractive index field. The method is of the onion-peeling type, and was developed specifically to accommodate the features of fringe patterns obtained from reference-beam interferometry.

Numerical Inversion of Laplace Transforms
2004In this chapter we present some procedures for numerically computing inverse Laplace transforms. Several methods based on different approaches have been proposed during the past fifty years. The numerical computation of an inverse Laplace transform is not readily done. It is a so-called ill-conditioned or ill-posed problem. In Chapter 6 we saw that the
