Introduction: Many natural phenomena have many variables that make it difficult to find relationships between them using common mathematical methods. This problem, along with the impossibility of measuring all elements of nature, has led to a major evolution in the way of understanding and explaining phenomena. In this way, one can use the fractal geometry with the theory that many natural phen...
In terms of the present short-term load forecasting(STLF) methods, whether the linear or the nonlinear, neither could meet the STLF requirements better with the rapid developments of electrical power systems and electrical power markets, and so a novel STLF method was proposed based on fractal theory in this paper. Firstly, the paper investigated the fractal characteristics of power system load...
تجزیه و تحلیل شدت(i)، تجمع(ρ)، میانگین طول خطواره(µ) و تقاطع(n)، از پارامترهای کاربردی در محاسبات آماری گسلها و شکستگیها است که در واحد سطح بیان می شوند. در این تحقیق بارز سازی خطواره ها با به کار گیری تصویر اسپات5 انجام شد. شکستگیها در دو دسته سیستماتیک با روند های شمال غربی – جنوب شرقی که روند غالب منطقه هستند و شمال شرقی – جنوب غربی دسته بندی شدند. با توجه به وسعت منطقه و میزان توزیع شکستگیه...
We start this article by rebuilding higher operads of weak higher transformations, and correct those in cite{Cambat}. As in cite{Cambat} we propose an operadic approach for weak higher $n$-transformations, for each $ninmathbb{N}$, where such weak higher $n$-transformations are seen as algebras for specific contractible higher operads. The last chapter of this article asserts that, up to precise...
Abstract Purpose - The aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. Top-down hierarchies are typically characterized by command and control systems of the authority t...
Main aim of this study is to determine relationship between lead and silver mineralized zones using the Concentration-Volume (C-V) fractal modeling and logratio matrix based on subsurface data in Mehdiabad Zn-Pb-Ag deposit, central Iran. First, Pb and Ag raw data were analyzed by statistical processes and their histogram have similar shape. Next, Geostatistical modeling was carried out for the ...
Understanding critical properties of non-equilibrium processes [1] is still a challenging problem of contemporary statistical physics. Of particular interest (both theoretical and practical) are the dynamical growth phenomena. The model for the two-dimensional (2D) growth (Diffusion Limited Aggregation) was introduced almost thirty years ago by Witten and Sander [2]. Structures grown by DLA loo...
The presence of correlated randomness in EEG time series signal buried in random noise was analyzed with the Higuchi fractal algorithm. The signal recognition algorithm design was built on the fact that the theoretical fractal dimension value of 2 is an indicator for a white noise time series and correlated randomness would alter the fractal dimension value from 2. However, the limited number o...
