On aggregate composite indicators

Journal of the Operational Research Society, 2017
In this paper it is shown that the unweighted arithmetic average is the theoretically consistent scheme to aggregate composite indicators, derived from the benefit-of-the-doubt model, across decision-making units.

Timber-Lightweight Aggregate Composite Floor Structure

Materials Science Forum, 2012
Nowadays, composite structures based on wood are frequently used. In civil engineering, mostly timber-concrete composite structures are used, particularly in reconstruction of old timber girder floor structures or manufacture of new ones at the reconstruction of old buildings in areas exposed to frequent earthquakes. In new buildings it is mainly glued

The Lightweight Porous Fine Aggregate Composite Based on Secondary Raw Materials

Key Engineering Materials, 2019
The main objective of this study was to carry out more detailed research on the effects of the amount of cement paste on the physical and mechanical properties of porous fine aggregate concrete (PFAC). Fine foamed glass aggregate (prepared of local glass

Compositional distributions in multicomponent aggregation

Chemical Engineering Science, 2008
Abstract We consider the granulation of two components, a “solute” (the component of interest) and an excipient. We specifically focus on cases such that the aggregation kernel is independent of the composition of the aggregating granules. In this case, theory predicts that the distribution of components is a Gaussian function such that the mean ...

Polycrystals, Composites and Aggregates

1999
This chapter covers mixtures which are not homogeneous. In a polycrystalline specimen of a single component only the orientation of the crystallites varies, while in composites and aggregates there are also two or more distinct components forming a mosaic throughout the solid.

Directing Effect of Bacterial Extracellular Polymeric Substances (EPS) on Calcite Organization and EPS–Carbonate Composite Aggregate Formation

, 2020
Mineralized structures generated under biological control are hierarchical composites that consist of biopolymer matrices and minerals. The biopolymer matrix in biological material is developed as membranes or as a network of fibrils, which has ...

Scattering enhancement in colloidal metal–organic composite aggregates

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012
Abstract In analogy to metal nanocomposites, the investigated hybrid organic–inorganic aggregates induce an enhancement of the scattered light. To explain the observed broadening of the absorption band and the wavelength dependence of the scattering, the systems can be considered as a nanoparticle composite.

Aggregation, aggregate composition, and dynamics in aqueous sodium cholate solutions

Journal of Colloid and Interface Science, 1980
The translational mobility of aggregates formed in aqueous sodium cholate solutions was obtained from the self-diffusion coefficient of solubilized decanol, which was determined using the capillary tube method with radioactive labeling. Combining these results with the self-diffusion coefficients of cholate ions, sodium ions, and water molecules the ...
