in this paper, we use a third degree b-spline function to construct an approximate solution forthird order linear and nonlinear boundary value problems coupled with the least square method. severalexamples are given to illustrate the efficiency of the proposed technique.

this study tries to expand the understanding of the relationship between transformational leadership and organizational innovation at the organizational level. this research proposes a conceptual framework to explain the components of transformational leadership while focusing on the relationship between each component and organizational innovation. a sample of 219 managers from 63 companies in...

iron, cobalt and copper are metals, which appear together in many real samples, both natural and artificial. recently a classical univariate micellar colorimetric method has been developed for determination of these metal ions. the organized molecular assemblies such as micelles are used in spectroscopic measurements due to their possible effects on the systems of interest. the ability of micel...

Abstract Analysis of the dynamic response a complex nonlinear system is always difficult problem. By using Volterra functional series to describe system, its analysis can be similar Fourier/Laplace transform and linear transfer function method analyse system's response. In this paper, for systems based on developed. Firstly, recursive formula least square established solve kernel vector, corres...
