Automatic recognition of animal vocalisations would be a valuable tool for a variety of biological research and environmental monitoring applications . We report the development of a software system which can recognise the vocalisations of 22 species of frogs which occur in an area of northern Australia. This software system will be used in unattended operation to monitor the effect on frog pop...

Let us consider a set of training examples described by continuous or symbolic attributes with categorical classes. In this paper we present a measure of the potential quality of a region of the attribute space to be represented as a rule condition to classify unseen cases. The aim is to take into account the distribution of the classes of the examples. The resulting measure, called impurity le...

This paper presents a method for inducing logic programs from examples that learns a new class of concepts called rst-order decision lists, de ned as ordered lists of clauses each ending in a cut. The method, called Foidl, is based on Foil (Quinlan, 1990) but employs intensional background knowledge and avoids the need for explicit negative examples. It is particularly useful for problems that ...

This paper deals with global attractor of a quasilinear parabolic system introduced in [1] by Horstmann and Winkler to model chemotaxis. Chemotaxis phenomenon is quite common in biosystem.The survival of many organisms, from microscopic bacteria to the largest mammals, depends on their ability to navigate in a complex environment through the detection, integration, and processing of a variety o...

Sidama farmers rely on rain-fed agriculture and experience a highly variable natural environment. Recurrent drought, erratic rainfall, and crop and livestock loss are common in midand lowland areas, but local people are not passive victims of the changing environment--they use accumulated knowledge and skills to respond to and buffer ecological changes. Based on freelists and in-depth interview...

The symmetric multistep methods developed by Quinlan and Tremaine (1990) are shown to suffer from resonances and instabilities at special stepsizes when used to integrate nonlinear equations. This property of symmetric multistep methods was missed in previous studies that considered only the linear stability of the methods. The resonances and instabilities are worse for high-order methods than ...

Karen Quinlan, the American girl who has lain in deep coma for many months, is still 'alive', that is to say, her heart is still beating and brain death has not occurred. However, several other cases have raised difficult issues about the time of death. Dr Skegg argues that there is a case for a legal definition of death enshrined in statutory form. He suggests that many of the objections to a ...

This paper presents a knowledge/rule based approach to continuous speech recognition. The proposed recognition system (Samouelian, 1994) uses a data driven methodology, where the knowledge about the structure and characteristics of the speech signal is captured explicitly from the database by the use of inductive inference (C4.5) (Quinlan, 1986). This allows the integration of features from exi...
