Abstract The pore-structure characteristics of hybrid basalt–polypropylene fibre-reinforced concrete were investigated by using mercury intrusion porosimetry. applicability various fractal models in characterising the HBPRC pore structure was compared. results show that types and content fibres different influences on cumulative volume basalt-polypropylene concrete. Compared with pore-volume so...

The robust process in memorising the Quran is expected to cause neuroplasticity changes brain. To date, analysis of limited binary images because greyscale requires usage more processing techniques. This research work aims explore and characterise complexity textual memorisation brain structures using fractal between huffaz non-huffaz applying global box-counting, Fourier dimension (FFD), volum...

We have undertaken the task to calculate, by means of extensive numerical simulations and by different procedures, the cluster fractal dimension (d f ) of colloidal aggregates at different initial colloid concentrations. Our first approach consists in obtaining d f from the slope of the log-log plots of the radius of gyration versus size of all the clusters formed during the aggregation time. I...

In this paper, the optical properties of one dimensional fractal structures are investigated. We consider six typical fractal photonic structures: the symmetric dual cantor-like fractal structure, the asymmetric dual cantor-like fractal structure, the single cantor-like fractal structure, the symmetric dual golden-section fractal structure, the asymmetric dual golden-section fractal structure a...

Molecular dynamics simulation is applied to study the electroosmotic flow in rough nanochannels, with particular attention given to the fluid–solid interactions. In the simulation, the surface roughness is characterized by a fractal Cantor. The roles of roughness height and fractal dimension on nanoscale electroosmotic flow are examined and analyzed. The concentration distributions, zeta potent...

Diffusion towards a fractal adsorber is a well-researched problem with many applications. While the steady-state flux towards such adsorbers is known to be characterized by the fractal dimension (D{F}) of the surface, the more general problem of time-dependent adsorption kinetics of fractal surfaces remains poorly understood. In this Letter, we show that the time-dependent flux to fractal adsor...

Two-point correlation function of galaxy distribution shows that the structure in the present Universe is scale-free up to a certain scale (at least several tens Mpc), which suggests that a fractal structure may exist. If small primordial density fluctuations have a fractal structure, the present fractal-like nonlinear structure below the horizon scale could be naturally explained. We analyze a...
