The method of Watson's Transformation, well known in high frequency scattering, is applied to a two-dimensional, orthogonal eigenfunction series of rectangular harmonic functions, which provides the solution to a typical boundary value problem of Laplace's equation. A new infinite, so-called...

The paper describes the features of the new generation of digital signal processors, including the Intel 2920 and Texas Instrument TMS320, and their suitability for continuous system simulation. Whilst these devices have applicability for high-speed, real-time simulation, their lack of...

The description of the boundary element method, B.E.M., for transient heat conduction problems is given. A simple count of the number of function evaluations concludes that the application of B.E.M. to such problems can be expensive in spite of the good accuracy.

AUTOSIM is an automatic, discrete event simulation generator developed by the Operations Research Section at the BHP Newcastle Steelworks. It has now been used for a number of years in developing simulation models in an industrial environment. The system to be simulated is first described as an...

A review of the recent results on solving various system problems via orthogonal polynomial aeries and Fourier series is presented. An attempt is made to unify these results and apply them to particular analysis and synthesis problems such as identification, solution of state-space equations ,...

A simple and efficient method to characterize beam motion in particle accelerator simulations, using the Hadamard transform, is presented. The importance of computational efficiency in this particular application is explained and some limitations of the method are indicated.

The systems of Haar function (HF), Rademacher functions (RF), Walsh functions (WF), and block pulse functions (BPF) have played a significant role in the fields of applied mathematics and engineering applications so far in the 20th century. Some of these systems of piecewise constant basis...

Discrete event digital simulation techniques can play a useful role in the design phase of major engineering projects. An example of such an application is described. It concerns a simulation study of a proposed coal transhipment terminal to be built on Batam Island, Indonesia. The study...

The use of complementary variational principles in finite element analysis is examined. It is shown that complementary finite element solutions provide an element by element measure of the accuracy of the solution. By solving a problem repeatedly, beginning with a coarse mesh and refining those...
