in this paper, we solve the quadratic $alpha$-functional equations $2f(x) + 2f(y) = f(x + y) + alpha^{-2}f(alpha(x-y)); (0.1)$ where $alpha$ is a fixed non-archimedean number with $alpha^{-2}neq 3$. using the fixed point method and the direct method, we prove the hyers-ulam stability of the quadratic $alpha$-functional equation (0.1) in non-archimedean banach spaces.
this paper is concerned with the economic valuation of the coral reef within kish island in persian gulf of iran. for calculating this value, all components of use and non-use values are estimated and then according to each of them, suitable method has applied. many different evaluation tools such as contingent valuation method, zonal travel cost method, replacement cost, avoided cost method, ...

in this study, catalyst of rutile titanium dioxide nanoparticles (rtio2-np) has been investigated for the removal and reduction of unburned hydrocarbons as benzopyran. to evaluate and calculate the thermodynamic properties of this aim, pollutants are closed to the nanoparticles and converted them into other products and the carbon dioxide molecules are simulated in the 12th steps. the geometric...
SUMMARY This review discribes some of the morphological tools which have allowed not only to discribe the chemical nature of neuronal pathways in the central nervous system but also to approach their physiology and their functions: Enzyme histochemistry; this technique shows the entity of an enzyme in nervous tissue. Immunocyto-histochemistry; based on antigenantibody reaction constitute the ...
compound (n,n-bis (salicylidene) 1,2-diaminophenylene) was prepared by condensation of ethanolsolution of 2-hydroxybanzaldehyde and 1,2-diaminophenylene. the compound was characterized by1h nmr, infrared spectroscopy (ft-ir) data and analytical data. the geometrical parameters andenergies have been obtained from density functional theory (dft) b3lyp method and hartree-fock (hf) method with 3-21...
this paper describes an approximating solution, based on lagrange interpolation and spline functions, to treat functional integral equations of fredholm type and volterra type. this method can be extended to functional dierential and integro-dierential equations. for showing eciency of the method we give some numerical examples.
The functional method is a new test theory using a new scoring method that assumes complexity in test structure, and thus takes into account every correlation between factors and items. The main specificity of the functional method is to model test scores by multiple regression instead of estimating them by using simplistic sums of points. In order to proceed, the functional method requires the...
Completely iterative monads of Elgot et al. are the monads such that every guarded iterative equation has a unique solution. Free completely iterative monads are known to exist on every iteratable endofunctor H, i. e., one with final coalgebras of all functors H( ) + X. We show that conversely, if H generates a free completely iterative monad, then it is iteratable.
A sequence of functions (curves) collected over time is called a functional time series. Functional time series analysis is one of the popular research areas in which statistics from such data are frequently observed. The main purpose of the functional time series is to predict and describe random mechanisms that resulted in generating the data. To do so, it is needed to decompose functional ti...
