TL;DR: Through the process of establishing new similarity measures, one not only can determine the similarity between two contours but can also identify the particular geometric relation present between them.
Abstract: New measures of similarity between two contours are proposed. They are based on the residual errors of the optimal bivariate transforms between the two contours. Through the process of establishing new similarity measures, one not only can determine the similarity between two contours but can also identify the particular geometric relation present between them. The results of contour recognition and identification experiments demonstrate the usefulness of the new similarity measures in real world applications.

TL;DR: Spermathecae and associated structures in 18 species of New Zealand Aradidae representing all 8 subfamilies are described and the bearing of these on the relationships of the subfam families and on taxonomy is commented on.

Journal ArticleDOI
TL;DR: In this paper, all the higher order terms in the expansion of the lineshape functions are proved to be finite at the resonance peaks as well as in the wings of the absorption lines, implying that the critique is unreasonable.

Journal ArticleDOI
TL;DR: Based on the projection operator method, a theory of direct interband optical transition due to electron-phonon interaction is introduced in this paper, where the line shape function contains the phonon energy in a different way in the energy denominators.

TL;DR: Substitution reactions of Δ-cis-β-[Rh(SS-EDDp)Cl 2 ] − with amino acids, however, resulted in isomerization to the Δ cis-α-product or retention of configuration depending on the reaction condition.

Journal ArticleDOI
TL;DR: The relationship between the dyeing behaviors and the changes in fine structure has been discussed in this paper, where the authors measured changes in amorphous and crystalline regions of the fibers, and the structural change in fibers was related to the dyeability for C I. Disperse Violet 1 (1, 4-diaminoanthraquinone).
Abstract: Nylon 6, heat-set nylon 6 and nylon 66 have been treated with aqueous formic acid solutions of various concentrations for a predetermined time at a fixed temperature. The changes in weight loss, water absorption, shrinkage, crystallinity, crystallite size were measured in order to estimate the change in amorphous and crystalline regions of the fibers, and the structural change in fibers was related to the dyeability for C. I. Disperse Violet 1 (1, 4-diaminoanthraquinone). These parameters, except the dyeability, increased with increasing the concentration of formic acid until the fibers were dissolved completely in concentrated formic acid solutions (ca. 59% solution for nylon 6, ca. 62% solution for heat-set nylon 6, and ca. 68% solution for nylon 66). In particular, the loss in weight gradually increased when the samples were treated with formic acid solution at a concentration lower than 50%. Correspondingly, the dyeability gradually increased at a concentration lower than 50%. However, the dye uptake showed a marked decrease when the loss in weight was markedly observed. From results obtained the relationship between the dyeing behaviors and the changes in fine structure has been discussed.
