A voltammetric electronic tongue consisting of several metal electrodes is developed and used to detect TNT in an acetonitrile-water mixture. Viscovery SOMine and feed-forward neural networks are used to detect TNT traces and to design the electronic tongue for optimal detection properties.

A reuse design decision support system based on self-organizing maps

Feldhusen, J., Nagarajah, A., Schubert, S., & Brezing, A. (2011). In The Future of Design Methodology (pp. 67-77). Springer, London.

This article aims at a decision support system for design reuse. Viscovery SOMine is used to create a model of existing hood lock systems of an automotive supplier. By applying the model to specifications for a new hood lock system, the most similar existing solutions can be identified and their visualized properties can be used to support design decisions.

Composite panel damage detection using ultrasonic testing and neural networks

Kral, Z., Horn, W., & Steck, J. (2009).

The focus of this article is to create a structural health-monitoring system for composite components used in modern aircrafts and wind turbines. Viscovery SOMine is used to analyze the high dimensional ultrasonic sound measurements obtained during operation or from different testing methods to detect structural damages.

Clustering of pressure fluctuation data using self-organizing maps

Ogihara, M., Matsumoto, H., Marumo, T., & Kuroda, C. (2009, August). In International Conference on Engineering Applications of Neural Networks (pp. 45-54). Springer, Berlin, Heidelberg.

The pressure fluctuations in a microchannel traversed by an aqueous liquid and an organic liquid are analyzed with respect to the operating conditions of the microchannel. Viscovery SOMine is used in a multi-level approach to first cluster the time series of pressure measurements and then to order the operating conditions according to the distribution of the associated time series in the cluster model. This procedure is repeated once to restrict the model to the interesting cases.

Making sense of sensor data

Cook, D. J. (2007). IEEE Pervasive Computing, 6(2).

This article examines tools and algorithms for analyzing sensor data. Clustering and exploration with Viscovery SOMine is compared to principle component analysis, singular value decomposition and other techniques.

Classification of metal ions according to their complexing properties: a data-driven approach

Pletnev, I. V., & Zernov, V. V. (2002). Analytica Chimica Acta, 455(1), 131-142.

Factor, cluster and self-organizing map analyses are applied to the stability constants of complexes of metal ions and hydrogen with 3960 ligands. Both direct clustering and clustering on the basis of factor analysis established the existence of six different classes of similar cations. The self-organizing map created with Viscovery SOMine visually represents that similarity.
