Parameter identification of constrained data by a new class of rational fractal function

چکیده
This paper sets a theoretical foundation for the applications of fractal interpolation functions (FIFs). We construct rational cubic spline FIFs (RCSFIFs) with quadratic denominator involving two shape parameters. The elements iterated function system (IFS) in each subinterval are identified befittingly so that graph resulting $\mathcal{C}^1$-RCSFIF lies within prescribed rectangle. These parameters include, particular, conditions on positivity $\mathcal{C}^1$-RCSFIF. problem visualization constrained data is also addressed when lying above straight line, proposed curve required to lie same side line. illustrate our scheme some numerical examples

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Determining fractal parameter and depth of magnetic sources for ardabil geothermal area using aeromagnetic data by de-fractal approach
The Ardabil geothermal area is located in the northwest of Iran, which hosts several hot springs. It is situated mostly around the Sabalan Mountain. The Sabalan geothermal area is now under investigation for the geothermal electric power generation. It is characterized by its high thermal gradient and high heat flow. In this study, our aim is to determine the fractal parameter and top and botto...

15 صفحه اولA New Class of Symmetry Reductions for Parameter Identification Problems
This paper introduces a new type of symmetry reductions called extended nonclassical symmetries that can be studied for parameter identification problems described by partial differential equations. Including the data function in the parameter space, we show that specific data and parameter classes that lead to a reduced dimension model can be found. More exactly, since the extended nonclassica...
