Numerical Inversion of a Characteristic Function
Biometrika, 1973SUMMARY A method is described for finding a bound on the error when a version of the usual characteristic function inversion formula is evaluated by numerical integration. The method is applied to the calculation of the distribution function of a quadratic form in normal random variables.

Numerical inversion of characteristic functions
Scandinavian Actuarial Journal, 1977Abstract To anyone working with characteristic functions, or with Laplace transforms of a non-negative random variable, the three papers by Harald Bohman (1971, 1974, 1975) are invaluable. Numerical integration over an infinite interval is extraordinarily beset with pitfalls (vide Davis & Rabinowitz, 1975) and the publication of actual results achieved

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.
