Signal processing with sinusuidal waveforms as basis functions has dominated the electrical engineering discipline. Yet, a large class of signals arising from natural processes may be more efficiently represented by exponentials with complex or purely real exponents, rather than by exponentials...

This paper considers the numerical solution of the elliptic self-adjoint second order and the biharmonic equations using a variety of accelerated versions of the Modified Alternating Direction Preconditioning (MADP) method developed in [4]. The resulting iterative schemes possess rates of...

An approximate method based on the diffusion equation is presented for analyzing a non-Markovian machine repair problem. The basic argument used in this approximation is that in the repair stage, the number of failed machines at time t, N(t), is almost always non-empty under heavy-traffic...

In the south east of South Australia the Woods and Forests Department manages a large area of radiata pine plantations that provide log to a variety of utilisation plants; including three large sawmills, smaller sawmills, a pulpmill, a ply mill and a preservation plant.

A novel realization method of two-dimensional digital filters based on well known transforms (Discrete Fourier, Walsh-Hadamard, etc.) is presented. The method proposed here creates realizations which have parallel structure and high throughput rates. It is shown that such realizations are...

Geostatistical techniques are used today to obtain the best linear unbiased estimate for block parameter values in mineral deposits. For mineral deposits with sample data that is lognormally distributed the proportional effect is often observed where there is a linear relationship between the...

After a short review of the data compression technique through orthogonal transforms, and a brief account of the basic features of multi-microprocessor systems, a fast Walsh transform-based multi-microprocessor data compression system is presented and tested using real ECG waveforms.

The derivation of a mathematical model for heat and mass transfer in a packed bed reactor subject to vertical fluid flow is discussed. If certain simplifying assumptions can be made, and if there is no vertical movement of the bed, then the model can be reduced to a simple form in two dimensions...
