in this paper, a new and ecient approach based on operational matrices with respect to the gener-alized laguerre polynomials for numerical approximation of the linear ordinary dierential equations(odes) with variable coecients is introduced. explicit formulae which express the generalized la-guerre expansion coecients for the moments of the derivatives of any dierentiable function in terms...
in this study we produced a new method for solving regular dierential equations with step size h and taylor series. this method analyzes a regular dierential equation with initial values and step size h. this types of equations include quadratic and cubic homogenous equations with constant coecients and cubic and second- level equations.
فرایند احتراق درجا در حقیقت همان فرایند تزریق گاز به مخزن است با این تفاوت که در فرایند احتراق درجا از گرما جهت بهبود بازیافت استفاده می شود. در این فرایند هوا از طریق یک چاه تزریقی به مخزن تزریق شده که با سوزاندن بخشی از نفت مخزن، موجب تولید حرارت می شود. در اثر نیروی رانش آب و نیز گازهای گرم تولید شده ناشی از سوختن مواد هیدروکربنی، نفت مخزن به سمت چاه های تولیدی حرکت می کند. با توجه به جهت ...
Laser induced fluorescence (LIF) excitation scans and dispersed fluorescence (DFL) spectra have been recorded for two four-carbon α,ω-diphenyl systems, diphenyldiacetylene (DPDA, φ-C≡C-C≡C-φ) and trans-diphenylvinylacetylene (DPVA, φ-CH≡CH-C≡C-φ) as isolated molecules cooled in a supersonic expansion. While these molecules have similar conjugation length, they exhibit strikingly different vibro...

Th eir storage capacity is comput ed as well as the attrac tion basin of each memorized pattern. We show how such systems can be used when the patterns to be memorized have a subset of relevant features; "s...
Reaction of (NBu3H)3[W(CN)8]·H2O and linear trinuclear complexes [Cu(II)2L2Ln(III)(NO3)3] (L = 2,6-di(acetoacetyl)pyridine, Ln = Eu (1), Gd (2), Tb (3) and Dy (4)) leads to the formation of four one-dimensional (1D) complexes. Single crystal X-ray analysis reveals that [W(CN)8](3-) bridges between the [Cu(II)2L2Ln(III)] sub-building units to construct the alternative chains. Magnetic investigat...
This study provides an analysis of the aid-private capital flows-growth nexus for Ghana. It is premised on the argument that Ghana’s new status as a middle income country plus the start of oil production is bound to result in a reduction in ODA inflows in the long term. However in the short to medium term ODA will remain an important component in the country’s fiscals as well as an important to...
In this paper we focus on the relationship between remittance inflows and financial inclusion in developing countries. We present single equation estimates on remittances and financial inclusion, and system estimates in which economic growth is explained by e.g., financial inclusion, and financial inclusion by, e.g., remittances inflows. These regressions clearly confirm our main hypothesis tha...
This working paper examines the validity of the claim that ‘scaling up’ ODA in developing countries will cause ‘Dutch Disease’ effects that slow growth and human development. The most common concerns are increased inflation and exchange-rate appreciation. Consistent with a recent IMF re-appraisal, the paper maintains that such problems can be mitigated if ODA is properly ‘spent’ and ‘absorbed’....
