| Research Abstract |
In this research we have developed a smell measurement system by using quartz crystal microbalances and we have found the fundamental components from smell data by using an independent component analysis. Using the self-organizing feature map, we have clustered the independent components and using gas-chromatography, we have identified chemical components of the fundamental elements. Using orthogonal representation of the smell by the fundamental components, we have derived the orthogonal representation of the smell (the smell decomposition). By superposing the chemical components according to the ratio of the weighting factors of the decomposition, we haveproduced a smell (smell composition).
