Rates of increase in the number of parameters of a Fourier factor demand system that imply asymptotically normal elasticity estimates are characterized. The main technical problem in achieving this characterization is caused by the fact that the eigenvalues of the sample sum of squares and cross products matrix of the generalized least squares estimator are not bounded from below. This problem ...
The discrete fractional Fourier transform (DFRFT) is the generalization of discrete Fourier transform. Many types of DFRFT have been derived and are useful for signal processing applications. In this paper, we will introduce a new type of DFRFT, which are unitary, reversible, and flexible; in addition, the closed-form analytic expression can be obtained. It works in performance similar to the c...
We use the simulation model ofCbalfallt and Gallant (IUS5) to investigate the fit of a Fourier flexible form to a cost function when interest is t.o estimate elasticities of substitution. The data is subject to errors in variables and the estimation method is seemingly unrelated regressions. \IVe use two approximating Fourier functional forms * Hesearch supported by C:-IPq ** Banco do Brasil, C...
This paper investigates the performances of artificial neural networks approximation, the Translog and the Fourier flexible functional forms for the cost function, when different production technologies are used. Using simulated data bases, the author provides a comparison in terms of capability to reproduce input demands and in terms of the corresponding input elasticities of substitution esti...
The work is devoted to the issues of stationary heat transfer. article presents a solution for distribution temperature field in rectangular plate. At same time, law change thermal conductivity along one coordinates known. Heat exchange at two opposite ends plate occurs under boundary conditions third kind, there no other two. found by decomposition into functional series. As result, an analyti...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
In this study, amino functional groups were chemically bonded to the surface of newly synthesized KIT-6 mesoporous magnetite nanoparticles (MMNPs) by post-toluene reflux synthesis method. This method treats calcined mesoporous nanoparticles with the functional organosilanes. Physical and chemical structures of the synthesized mesoporous magnetite nanoparticle...
