Multidimensional analysis of similarity data was applied to the domain of a spoken vowel. Thirty-two male speakers provided samples of the vowel [æ]. Judgments of degree of similarity between each pair of vowels were obtained from 100 observers. The similarity judgments provided estimates of psychological distances between the vowels. The distances were used to construct an auditory space, Euclidean in nature, for the vowel samples. Dimensionality of the space was appropriate to account for the distances between vowels. Acoustic data were employed to identify the dimensions. The dimensions related well to frequency and amplitude properties of first, second and third formants, and good predictions as to locations of the vowels in space could be made from the acoustic data. The multidimensional scaling method shows promise as a method for structuring auditory space and for understanding processes of vowel perceptions.

Antivirus software industry is growing rapidly in the world in 2018. The domestic antivirus software industry must be able to compete on a global scale. To face free trade, Indonesia's antivirus software industry must be able to know its position in the minds of consumers, especially domestic consumers. In this research, Smadav will represent the antivirus software industry from Indonesia.In this research want to know how the position of smadav compared with its current competitors, namely Avast, Avira, AVG, Kaspersky, McAfee and Norton. This research is only done to map antivirus software based on similarity according to respondent's perception.This research uses Multidimensional scaling (MDS) method through SPSS software program version 23. The results showed that there are three groups of different antivirus software based on similarity level according to the respondent's perception.On the two-dimensional and three-dimensional maps Norton antivirus software, Avast and Avira have similar resemblance according to the respondent's perception, because the location is closest and is in the same quadrant. Smadav differs according to perceptions of respondents. AVG, McAfee and Kaspersky have similarities according to respondents' perceptions.

In this paper, we presented for the first time a multidimensional scaling approach to find the scaling as well as the ranking of triangular fuzzy numbers. Each fuzzy number was represented by a row in a matrix, and then found the configuration points (scale points) which represent the fuzzy numbers in . Since these points are not uniquely determined, then we presented different techniques to reconfigure the points to compare them with other methods. The results showed the ability of ranking fuzzy numbers

12 students rated the experienced similarities among 16 compound visual-auditory stimuli. Each of 4 colors was combined with each of 4 musical chords to form 16 color-chord impressions. Nonmetric multidimensional scaling of the 16 × 16 matrix of similarity data yielded an orderly and interpretable solution in two dimensions. The results suggest that the color-chord combinations produced psychologically integrated impressions which varied along orthogonal dimensions of darkness (versus lightness) and spread (versus compactness) of chords.

Successive intervals scaling and equal intervals scaling as a preliminary step to multidimensional scaling analysis were compared. The effects of an exponential transformation on the resultant structure were also investigated. For judgments involving similarity of electronics job tasks, neither scaling method nor exponential transformation seemed to affect the emergent structure to any great extent.
