The morphological description of fractal agglomerates is generally reduced to only two parameters, namely the mass dimension and its prefactor. In most evolved approaches, a stretching exponent also introduced, while packing factor preferred any case, current analytical morphology accurate for sufficiently large agglomerates, which due limited spatial extension clusters that are actually quasi-...

Many research works on content-based image retrieval have made use of image features. On the other hand, many kinds of image features have also been developed in the research field of wmputer vision and image analysis. The fractal signature is an example, which is based on the assumption that an image consists of a single fractal. For complex natural objects like grass and trees, however, a mix...

Building applications from of-the-shelf pieces, like libraries and components, is a promising approach to the future of software development. As such pieces are a subject to reuse, they have to have their interfaces and semantics clearly defined. To combine components from various vendors, one need a way to reason about component compatibility. Our experience with distributed component-based ap...

54 Generally, a fractal most often referred to as “a rough shape that can be subdivided in parts, each of which is (at least approximately) a reduced-size copy of the whole.” The father of fractal geometry Benoît Mandelbrot formulated this term in 1975. A fractal has a complicated shape. Certain features characterize a graphical representation of the fractal by mathematical equation: it is self...

adsorption of p-nitrophenol by three different activated carbons (f100, s.e.i. and b.d.h.) was carried out at 301 k and at controlled ph conditions. two different adsorption models (langmuir model and freundlich model) were studied and compared. the adsorption capacity of the carbons depends on the point of zero charge (pzc) and surface area of the carbons. adsorption of the solute at higher ph...

We present the results of the first reduced model simulations of the nonlinear development of the two-plasmon decay instability in an inhomogeneous plasma, including properties of the 3/2 harmonic emission. A sharp increase in radiation and Langmuir turbulence fluctuation levels occurs above a threshold laser intensity that depends on initial fluctuation levels. We study the competition between...

This paper seeks to check the validity of a hypothesis known as the “apparent fractal conjecture” (Ribeiro 1999: gr-qc/9909093), which states that the observed fractal structure of large-scale distribution of galaxies arises when some observational quantities, selected by their relevance in fractal characterization, are calculated along the past light cone. Since general relativity states that ...

This paper puts forward the concept of fractal company is in the process of online shopping. According to the characteristics of the network shopping, the paper establishes the mathematical model of fractal clustering, and uses the fractal dimension to describe and depict Fractal Company. Online shopping is actually the management of the entire supply chain. Based on similar structure of fracta...

All the geophysical phenomena including river networks and flow time series are fractal events inherently and fractal patterns can be investigated through their behaviors. A non-linear system like a river basin can well be analyzed by a non-linear measure such as the fractal analysis. A bilateral study is held on the fractal properties of the river network and the river flow time series. A movi...

Several models based on the diffusion-limited aggregation (DLA) model were proposed and their scaling properties explored by computational and theoretical approaches. In this paper, we consider a new extension of the on-lattice DLA model in which the unitary random steps are replaced by random flights of fixed length. This procedure reduces the screening for particle penetration present in the ...
