Numerical validation of a population balance model describing cement paste rheology [PDF]
, 2020 Rheology control is essential during the period in which cement and concrete pastes are encountered in the fresh state, due to the fact that it directly affects workability, initial placement and the structural performance of the hardened material ...

Química Nova, 2011 The processing of national petroleums causes many operational problems due to the asphaltene aggregation phenomena. To evaluate the behavior of these phenomena, a study based on optical scan technique was carried out to understand the behavior of pure ...

Diffusion-Limited Aggregation on Curved Surfaces [PDF]
, 2010 We develop a general theory of transport-limited aggregation phenomena occurring on curved surfaces, based on stochastic iterated conformal maps and conformal projections to the complex plane. To illustrate the theory, we use stereographic projections to

Aggregation phenomena in lyotropic chromonic liquid crystals
Communications in Nonlinear Science and Numerical Simulation, 2023 We study the aggregation phenomenon in lyotropic chromonic liquid crystals as the molecular concentration changes and condensing agents are added into the system. Using properties of the critical points of the Oseen-Frank energy of a nematic liquid crystal, combined with the geometric constraints of the hexagonal columnar chromonic phases, we show that

Dispersion state phase diagram of citrate-coated metallic nanoparticles in saline solutions
Nature Communications, 2020 Citrate-stabilized metallic colloids are key materials towards chemosensing and catalysis applications. Here the authors introduce a new theoretical model to estimate how the stoichiometry of citrate molecules absorbed onto spherical metallic ...

Aggregation bias and its drivers in large‐scale flood loss estimation: A Massachusetts case study
Journal of Flood Risk Management, 2022 Large‐scale estimations of flood losses are often based on spatially aggregated inputs. This makes risk assessments vulnerable to aggregation bias, a well‐studied, sometimes substantial outcome in analyses that model fine‐grained spatial phenomena at ...

Scientific Reports, 2021 Formation of non-sessile, auto-aggregated cells of Staphylococcus aureus contributes to surface colonization and biofilm formation, hence play a major role in the early establishment of infection and in tolerance to antimicrobials.

Growing dynamics of Internet providers [PDF]
, 2001 In this paper we present a model for the growth and evolution of Internet providers. The model reproduces the data observed for the Internet connection as probed by tracing routes from different computers.

Direct simulation of aggregation phenomena [PDF]
Communications in Mathematical Sciences, 2004 We present here an algorithm to simulate the motion of rigid bodies subject to a non–overlapping constraint, and which tend to aggregate when they get close to each other. The motion is induced by external forces. Two types of forces are considered here: drift force induced by the action of a surrounding fluid whose motion is prescribed, and stochastic
