In the past decade filaments have been recognised as a major structural element of interstellar medium, densest these hosting formation most stars. some star-forming molecular clouds converging networks filaments, also known hub filament systems, can be found. These hubs are believed to preferentially associated massive star formation. As today, there no metrics that allow systematic quantifica...

OBJECTIVE At the end of training, students seem to lack a basic understanding of how to take an organised, relevant medical and social history using a patient-centred approach. The aim of developing the map described in this paper was to provide a framework for such an approach. METHODS Action research was used to continuously modify and refine an interview map that was used by medical clerks...

The GUARDIANS robot swarm is selforganising and can be seen as a hybrid of a (heterogeneous) swarm, a mobile ad-hoc network and an (evolving) topological map of the environment. We assume that robots cooperate in order to deploy themselves, search the area and construct a (online) map of the environment. We present a novel approach of distributing robots on site that takes advantage of a cooper...

Unsupervised topological ordering, similar to Kohonen’s (1982) Self-organizing feature map, was achieved in a connectionist module for competitive learning (a CALM Map) by internally regulating the learning rate and the size of the active neighborhood on the basis of input novelty. In this module winner-take-all competition and the 'activity bubble' are due to graded lateral inhibition between ...

A SpectrophoreTM is a one-dimensional descriptor that describes the three-dimensional molecular field surrounding a molecule generated by a given set of atomic properties. In a typical application, SpectrophoresTM are calculated from the molecular shape in combination with the electrostatic, lipophilic, softness, and hardness potential surrounding the molecules. Given that molecules with simila...

The need for better techniques, tools and practices to analyse ecological and economic systems in an integrated framework has never been so great. Self-organising map (SOM) methods are utilised for this purpose with two examples using regional and global data (ecological and economic) compiled by state and international institutions i.e. Waikato Regional Council and the World Bank. Sustainable ...

The recognition of optical characters is known to be one of the earliest applications of Artificial Neural Networks, which partially emulate human thinking in the domain of Artificial Intelligence. The current paper focuses on the use of neural network in order to mitigate the problems of digital handwriting recognition by using Self-Organizing Map model for fast processing and less processing ...

Navigation in and access to the contents of digital audio archives have become increasingly important topics in Information Retrieval. Both private and commercial music collections are growing both in terms of size and acceptance in the user community. Content based approaches relying on signal processing techniques have been used in Music Information Retrieval for some time to represent the ac...

The paper introduces a novel approach for interactive video browsing that makes video content fully transparent to the user. Video clips are analysed and indexed by two tree structures: a content index tree representing the content of automatically segmented video shots and a time index tree representing the temporal structure. The index top levels give an overview over the entire content. Subs...

The self-organising map (SOM) has been successfully employed as a nonparametric method for dimensionality reduction and data visualisation. However, for visualisation the SOM requires a colouring scheme to imprint the distances between neurons so that the clustering and boundaries can be seen. Even though the distributions of the data and structures of the clusters are not faithfully portrayed ...
