Martheron's turning bands method for the simulation of spatially correlated data in two or three dimensions requires that the relationship between the covariance obeyed by the realizations first generated on lines, and the covariance of the two or three dimensional process must be solved. In...

A notation system is proposed for the writing of the finite difference equations related to a conduction heat transfer problem in a composite medium with variable thermal properties. An example is worked out with Euler explicit, Euler implicit and Crank-Nicolson methods. Special care is taken of...

The following describes an intertemporal linear programming model capable of determining constrained optimal redevelopment strategies for case study fruit blocks in South Australia's Riverland. Both model specification and potential uses of the model are presented below, while results from...

This paper focuses on models of small or partial systems, which generally tend to be less complex than the usual type of models. Microcomputers provide an ideal vehicle for these exercises, and the capabilities, advantages and limitations of these are discussed. Philisophical advantages of this...

This paper discusses the application of Walsh functions expansion to reduce the order of a linear time-invariant system. First, Model reduction of linear continuous systems by matching the Walsh spectra of output responses of the original and reduced models, subject to the specific inputs, is...

The JINDALEE over-the-horizon radar has required modelling and simulation of both hardware and software concepts during its development. This paper describes three such applications: modelling and simulation of nonlinear radar receivers, validation of signal processing algorithms and data...

This paper is a survey of some applications of Chrestenson functions in multiple-valued logic design, pattern processing and system theory. Since a good survey on some applications of Spectral methods in Computer Science already appeared a few years ago [K81], we will try here to avoid...

An integral of Haar functions yields triangular waveforms at subintervals where the Haar functions initially exist. These waveforms can be expressed by Haar series. Coefficients of their series can be given in quasi binary numbers. If the solutions of ordinary differential equations(ODE) are...
