One of the most important economic concepts is evaluation and bankruptcy prediction. Financial events, which an organization could be, exposed to serious risks and it goes bankruptcy. Therefore, prediction and assessment bankruptcy enable organizations that to be familiar the financial risks and resolve their financial deficiencies. So in this paper, we discuss one of the most important economi...

a classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. the model takes into consideration the effect of diffraction outside the capture limit on the rate constants. the theory is used to calculate momentum transfer rate constant for cl- with trans-dichloroethylene and para-difluorobenzene. theoretical results are compared to...

a novel computational fluid dynamics and molecular kinetic theory (cfd-mk) method was developed to simulate the impingement of a nanodroplet onto a solid surface. a numerical solution of the navier–stokes equation using a volume-of-fluid (vof) technique was used to model nanodroplet deformation. dynamic contact angle during droplet impact was obtained by molecular kinetic theory. this dynamic c...

abstractaccording to public choice theory, the features of the tax structure effect on voters' perceptions from the tax burden, so they pay more cost for public goods, lower than the estimate. in this study has been investigated the relationship between tax and public expenditures in the iranian economy during 1360-1390 based on public choice theory to examine the level of government spend...

A finite element model based on the layerwise theory is developed for the analysis of transverse cracking in cross-ply laminated beams. The numerical model is developed using the layerwise theory of Reddy, and the von Kármán type nonlinear strain field is adopted to accommodate the moderately large rotations of the beam. The finite element beam model is verified by comparing the present numeric...

it seems using the maxwell-stefan (m-s) diffusion model in combination with the vacancy solutiontheory (vst) and the single-component adsorption data provides a superior, qualitative, andquantitative prediction of diffusion in zeolites. in the m-s formulation, thermodynamic factor (г) isan essential parameter which must be estimated by an adsorption isotherm. researchers usually utilizethe simp...
