A general method for approximate solution of one-dimensional Schrödinger equations with a wide range of square-integrable potentials is described. The potential is expanded ...

This paper introduces a novel approach for designing an analog circuit under simultaneous consideration of DC and AC design specifications. Such specifications are restricted ...

The results of filter design obtained by solving non-linear coefficient derived polynomial equations is reported. Taking Butterworth filters as an example, and working with ...

We present extensions to the computer algebra and multimedia environment Mathematica to enable students to investigate signal processing theory. Students interact with the ...

In this paper we give a comuter proof of a new polynomial identity, which extends a recent result of Alladi and the first author. In addition, we rovide computer proofs for ...

A symbolic procedure for deriving various finite difference approximations for the three-dimensional Poisson equation is described. Based on the software package Mathematica, ...

We present a Mathematica program which implements tensor calculus using index notation. Common operations, such as contractions, lowering and raising of indices, ...

Virtually every RF circuit or system design incorporates semiconductor devices such as mixers, diodes, switches, and amplifiers. To some extent, all of these devices exhibit ...

Applying the higher-order averaging method, we study the periodically forced, standard Duffing oscillator. A package of the computer algebra system, Mathematica, recently ...

Although the Johnson-Neyman problem has been well defined in the literature, computational problems have restricted its use by researchers. The computational problems can be ...
