Computer-Aided Numerical Inversion of Laplace Transform

Active and Passive Electronic Components, 2000
This paper explores the technique for the computer aided numerical inversion of Laplace transform. The inversion technique is based on the properties of a family of three parameter exponential probability density functions.

Numerical inversion of finite Toeplitz matrices and vector Toeplitz matrices [PDF]

, 1968
Numerical technique increases the efficiencies of the numerical methods involving Toeplitz matrices by reducing the number of multiplications required by an N-order Toeplitz matrix from N-cubed to N-squared multiplications.

Computational Approach for Differential Equations with Local and Nonlocal Fractional-Order Differential Operators

Journal of Mathematics, 2023
Laplace transform has been used for solving differential equations of fractional order either PDEs or ODEs. However, using the Laplace transform sometimes leads to solutions in Laplace space that are not readily invertible to the real domain by ...

Language influences on numerical development – Inversion effects on multi-digit number processing

Frontiers in Psychology, 2013
In early numerical development, children have to become familiar with the Arabic number system and its place-value structure. The present review summarizes and discusses evidence for language influences on the acquisition of the highly transparent ...

Numerical evaluation of two and three parameter Mittag-Leffler functions

, 2015
The Mittag-Leffler (ML) function plays a fundamental role in fractional calculus but very few methods are available for its numerical evaluation. In this work we present a method for the efficient computation of the ML function based on the numerical ...

Evolution law of dominant flow channel of water flooding in partially enclosed fault reservoir

Youqi dizhi yu caishoulu
A partially enclosed fault reservoir is a common reservoir type. The partially enclosed faults caused by low-order faults lead to different fluid flow and distribution laws of remaining oil between partially enclosed fault reservoirs and completely ...

Inverse Kinematics of a Serial Robot

MATEC Web of Conferences, 2016
This work describes a technique to treat the inverse kinematics of a serial manipulator. The inverse kinematics is obtained through the numerical inversion of the Jacobian matrix, that represents the equation of motion of the manipulator.

Numerical Approximation of Probability Mass Functions Via the Inverse Discrete Fourier Transform

, 2012
First passage distributions of semi-Markov processes are of interest in fields such as reliability, survival analysis, and many others. The problem of finding or computing first passage distributions is, in general, quite challenging.
