Effect of pulsating electrolysis parameters on the morphology and structure of Pd-Ag powder

Results are reported from a kinetic study of single and joint deposition of Pd and Ag, and of the morphology, structure and chemical composition of Pd-Ag powders deposited from aminonitrite electrolyte under potentiostatic and pulsating square-wave overpotential. It was established that the Pd content in the powder reaches 50% with increase in the overpotential amplitude and the pulse/pause ratio. The same conditions are required for the deposition of finely divided powders. The form of the Pd-Ag powder is dendritic, but it is less branched compared to that obtained under steady potentiostatic conditions.     

Graffiti: graph-based classification in heterogeneous networks

We address the problem of multi-label classification in heterogeneous graphs, where nodes belong to different types and different types have different sets of classification labels. We present a novel approach that aims to classify nodes based on their neighborhoods. We model the mutual influence of nodes as a random walk in which the random surfer aims at distributing class labels to nodes while walking through the graph. When viewing class labels as “colors”, the random surfer is essentially spraying different node types with different color palettes; hence the name Graffiti of our method. In contrast to previous work on topic-based random surfer models, our approach captures and exploits the mutual influence of nodes of the same type based on their connections to nodes of other types. We show important properties of our algorithm such as convergence and scalability. We also confirm the practical viability of Graffiti by an experimental study on subsets of the popular social networks Flickr and LibraryThing. We demonstrate the superiority of our approach by comparing it to three other state-of-the-art techniques for graph-based classification.

Volatilization of components from zirconia ceramics

Conclusions We investigated volatilization in isothermal conditions of solid solutions of oxides of calcium and yttrium in ZrO₂.The calcium oxide is intensely sublimited from the solid solution of zirconium dioxide, stabilized with CaO at 2000–2100°C. However, during soaking and rapid cooling, destabilization does not occur, even during sublimation of 70–75% CaO. With rise in temperature to 2400–2500°C and a 4 h soak, only 0.5% CaO is preserved in the solid solution, which leads to destabilization and conversion of a large part of the cubic form of ZrO₂ with calcium oxide by fusion, we note sublimation of part of the CaO, and the remaining quantity (3%) is adequate for complete conversion of the zirconia into the stable cubic form.Volatilization of the stabilizing additive occurs in the form of YO at substantially higher temperatures than volatilization of the calcium oxide from the solid solution of zirconium dioxide, stabilized with yttrium oxide. Simultaneously with this we note volatilization of zirconium dioxide in the form of ZrO and ZrO₂.For the use of zirconium dioxide at elevated service temperatures, we would recommend yttrium oxide as a stabilizing additive.Translated from Ogneupory, No. 1, pp. 49–52, January, 1968.     

Evaluation of the mechanical characteristics of soils from static-penetration data

Conclusions 1. The specific resistance of soil not only beneath the cone of the penetrometer but also against the friction couple should be used to define the prediction of the strength and deformation characteristics of silty-clayey soils more precisely from static-penetration data, and the type of clayey soils should also be considered for the strength characteristics.2. For penetrometers equipped with radiation-logging apparatus, it is possible to evaluate mechanical characteristics of soils under field conditions, using the soil's density in addition to the penetration parameters q and f.3. In developing regional statistical relationships, it should be remembered that the extent to which q and f influence . c, and E is determined largely by what types of soil the statistical sample represents and in what range the physical indicators of its conditions vary.4. To define the recommendations of Construction Rule and Regulation 1.02.07-87 more precisely, it is expedient to use resultant correlation relationships (6)–(8) to evaluate , c, and E from static-penetration data for the genetic groups of quartenary deposits investigated.Translated from Osnovaniya, Fundamenty i Mekhanika Grungov, No. 4, pp. 21–24, July–August, 1990.     

Density estimates on the unit simplex and calculation of the mode of a sample

This paper addresses reliable and efficient calculation of the mode of a multivariate sample, which is a classical fusion function. In particular, we focus on the inputs given on the unit simplex, when aggregating elements of Atanassov intuitionistic fuzzy sets, interval-valued fuzzy sets and their extensions, as well as compositional data. We outline the use of a specially designed 2-additive fuzzy measures and the Choquet integral for the purposes of reducing computational complexity in higher dimensions. We present computational analysis and benchmark four different methods of density-based mode estimation.

Design of weave patterns: when engineering textiles meets music

This study aims to present a novel approach in creation of new patterns for woven textiles, which is based on musical scores. Such a design method has not been presented in the literature. It is based on the similarity between the music notation and the 2D coding of woven patterns. Theoretical and practical details on application of the design method are discussed. Weave patterns, based on famous musical pieces, are presented together with exemplary color designs. The four ‘musical’ patterns and their color designs could be considered as successful first attempts that open up additional opportunities for design and production of original, unique fabrics.
