This is a simple program for calculation of diamagnetic dipolar and CSA relaxation, DD cross-relaxation and DD-CSA cross-correlation rates between user-specified nuclear spin ...

Within the lowest-order Born approximation, we present an exact calculation of the time dynamics of the spin-boson model in the ohmic regime. We observe non-Markovian effects ...

The main goal of this paper is to show how the computer algebra system Mathematica allows us to study and to develop some topics on Operator Theory. In particular, some ...

The control.m package solves some basic control engineering problems: calculation of zeros and poles of transfer functions, plotting of Nyquist diagrams, Bode diagrams, root ...

Designed to make problem solving fun by showing students how to use Mathematica to perform calculations. Covers topics in arithmetic, sequences, algebra, quadratic equations, ...

The attached notebook has a Mathematica function which tabulates elements in a given chemical formula and gives the number of respective atoms. From then on, it is easy to ...

In biology and medicine many substances and drugs enter the system not at regular time intervals but rather according to a random process. In the present article a situation ...

A network of polymer chains, which is undergoing an external deformation, is considered. Each of the network chains is linear and consists of segments interacting by nematic ...

In this work, the stress resultants and displacements (due to in-plane loading) of circular rods with variable cross-sections are calculated by using the initial values ...

A Mathematica implementation of the program LERG-I is presented that performs the reduction of the tensor integrals, encountered in one-loop Feynman diagram calculations, to ...
