Determination of the equivalent radii and fractal dimension of polystyrene latex aggregates from sedimentation coefficients
(Academic Press IncSan DiegoEUA, 1998)
Nonintrusive investigation of large Al-kaolin fractal aggregates with slow settling velocities
(2020-10-15)
Although a combination of aggregate characteristics dictate particle settling, it is commonly assumed that large particles have higher terminal velocities. This simplifying assumption often leads to overprediction of large ...
The effect of blending granular aggregates of different origin on the strength of concrete
(Elsevier Science, 2012-03-01)
This work correlates the resistance of concrete cores with the physical properties of the granular material forming it. A basic physical characterization is conducted, taking into account the origin of the grains involved ...
A note on Chambers's 'long memory and aggregation in macroeconomic time series'
(Escola de Pós-Graduação em Economia da FGV, 2003-10-07)
Chambers (1998) explores the interaction between long memory and aggregation. For continuous-time processes, he takes the aliasing effect into account when studying temporal aggregation. For discrete-time processes, however, ...
Structure properties and pore dynamics in aggregate beds due to wetting-drying cycles
(WILEY-V C H VERLAG GMBH, 2006-04)
Aggregate hierarchy and porosity changes in aggregate beds as a consequence of wetting-drying cycles were studied in two Andisols and one Mollisol from Chile, collected at two depths. Bulk density and indirect tensile ...
On the classification of mixed construction and demolition waste aggregate by porosity and its impact on the mechanical performance of concrete
(SPRINGER, 2010)
The properties of recycled aggregate produced from mixed (masonry and concrete) construction and demolition (C&D) waste are highly variable, and this restricts the use of such aggregate in structural concrete production. ...
On the advantage of sharing a holdfast: effects of density and occurrence of kin aggregation in the kelp Lessonia berteroana
(2014)
We investigated the density-dependent and genetic relatedness that regulate the occurrence of inter-individual (genet) fusion forming plurigenotypic organisms in the brown alga Lessonia berteroana. Recruitment generally ...
On the advantage of sharing a holdfast: effects of density and occurrence of kin aggregation in the kelp Lessonia berteroana
(Wiley & Sons, 2015)
We investigated the density-dependent and genetic relatedness that regulate the occurrence of inter-individual (genet) fusion forming plurigenotypic organisms in the brown alga Lessonia berteroana. Recruitment generally ...
Aggregator units allocation in low voltage distribution networks with penetration of photovoltaic systems
(Elsevier B.V., 2021-09-01)
The aggregator units are essential in implementing smart grids since they are responsible for connecting smart meters installed on the consumers and ensuring exchanging information with the utility control centers. This ...
