The Commonwealth Scientific and Industrial Research Organisation (CSIRO) Forestry and Forest Products has developed a PC-based fire spread prediction application that can be used by fire control officers as an aid in strategic planning and resource allocation. This computer application, called Siro Fire, is a DOS protected mode application that incorporates several fire spread models that can be applied to the two major fuel types found in Australia-grass and forest. It uses GIS-derived geographic maps and digital elevation models to calculate the probable spread of a fire across the landscape and displays the results on a graphical representation of the map of the area of concern. The application is being used in the South Australian Country Fire Service as both an operational and training tool. This paper outlines the evolution of previous fire spread simulation software, the development of SiroFire and how SiroFire carries out fire spread simulations using existing fire spread prediction algorithms.

This paper addresses the techniques used to produce a relatively low bit rate for speech coding. The technique initially explored in this work is the linear predictive coder, the most popular method referenced to date. This technique uses algorthims that describe the speech production process during voice and unvoiced sounds. The linear predictive coder attempts to approximate the vocal tract filter over a short period of time. The model, coupled with a specific excitation, can be used for speech synthesis.

A case study involving the use of simulation to analyze options to increase production of a copper production facility in Australia is reported here. A detailed and accurate model was developed capturing the factors affecting production and materials handling. The study resulted in prototype software with an Excel-based interface that allows the user to do further experiments with the model. Animation was used throughout the life cycle of the simulation. The paper illustrates various modeling issues faced and how they were resolved in the modeling of this copper production process. The model allows for experimenting with many options to increase production, including change of pot sizes, casting rates, storage, and other resources' capacities. The study is an example for the usefulness of computer simulation technology to analyze manufacturing systems.
