abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
For the calculation of static quantities, such as free energies, phase diagrams and screening masses, the euclidean lattice formulation of finitetemperature quantum fields offers a first-principle approach. For intrinsically real-time correlators, such as the spectral function, no first-principle nonperturbative formulation exists. In the last O(10) years the classical approximation at high tem...
In this article, the thermodynamic properties of Bi2212, as a function of oxygen pressure and temperature vaviations, have been studied. The results showed that variation of lattice parameters are directly' a function of temperature and conversely function of oxygen content. The experiments were set up at room temperature to 820 and different oxygen pressure from 5, 10, 50, 100 and 500 mb. It ...
In this paper, Wavelet Collocation Method has been used to solve nonlinear fin problem with temperature dependent thermal conductivity and heat transfer coefficient. Thermal conductivity of fin materials varies any type so that we consider thermal conductivity as the general function of temperature. Here we consider three particular cases, where we assume that thermal conductivity is constant,...
Analysis of brucellosis epidemics in ships of the Mediterranean fleet in the nineteenth century are most easily explained by aerosol transmission in grossly overcrowded, hot and humid confined spaces.
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
