Weed Eradication Feasibility Analysis

This model combines population dynamics and search theory to calculate the probability that a weed invasion will be eradicated based on the amount of time invested in searching for it.

Oscar's data capture program

Did you ever find yourself trying to read data off a graph for modelling purposes? It is a labourious process requiring rulers, a steady hand and a lot of manual calculations for interpolation. This program will save you a lot of time. All you need is to scan your graphs onto bitmap files. Read your bitmaps into OCapture and click on the points you want to read. That's all there is to it.

SCUAF version 5

Soil Changes Under Agroforestry

This program was originally developed by ICRAF with partial funding from ACIAR. The model has been used extensively to analyse agroforestry systems in Asia and Africa. As part of an ACIAR project I developed a new Windows-based version that uses spreadhseet files for input and output. Running SCUAF 5 requires Excel®, as this software is used by the model to handle data input and output. Despite this additional requirement, version 5 is a vast improvement on older versions, which were based on a laborious question-answer session under the DOS-operating system.

To install follow these steps:

Create a new folder (i.e. C:\SCUAF).
Extract the files from SCUAF5.ZIP into the new folder.
The relevant subfolders will be created in your SCUAF folder when the program is extracted
Run the model by clicking on the SCUAF5.exe icon.
