A highly accurate and effective scheme for solving the time-dependent Schrodinger equation is implemented using Mathematica. The present code achieves a precision of one part ...

In the analysis of the rate of technical progress, we often encounter this kind of problem: how does one treat the relationship between two kinds of indefinite variables? A ...

Packed array technology provides an optimized structure for certain classes of numerical expressions. This technology allows a valuable saving in the storage required and ...

Basic treatment of differential equations. What you will find here: Samples of numerical solution of discrete difference equations. Samples of symbolic solution of systems ...

In this paper, we describe a Mathematica program for the design of distillation columns, clearly a very important topic in chemical industry. In particular, we consider ...

The method of Sharp and Rosenstock for the calculation of Franck-Condon factors (J. chem. Phys. 41, 3453 (1964)) is revised. A few errors in the original contribution and in ...

We discuss the application of MATHEMATICA for automated, symbolic calculation of the cumulant equations of arbitrary order. Like moment equations, these partial differential ...

A complete closed-form solution to the inverse kinematics problem for a 4-DOF manipulator robot is proposed. With the discussion of the existence of the offset and the ...

Annular and perforated plates constitute vital components in mechanical engineering, such as in nuclear reactors. Natural frequencies of components have attracted extensive ...

The representation of the shape of a biconcave erythrocyte by a set of three parametric equations was achieved by using the expressions that transform the curvilinear ...
