Additive decompositions of harmonic functions play an important role in function theory and for the solution of partial differential equations. One of the best known results is the decomposition of harmonic functions as a sum of a holomorphic and an anti-holomorphic function. This decomposition can be generalized also to the analysis of quaternion valued harmonic function, where the summands ar...

Despite the large number of studies that draw on Programme for International Student Assessment (PISA) microdata in their analyses of the determinants of educational outcomes, no more than a few consider the relevance of geographical location. In going some way to rectify this, our paper examines the differences in educational outcomes between students attending schools in rural areas and those...

The paper explores firstly the impact of technological change on trade growth at the country level, using trade statistics and statistics on patenting activity in the US, across 20 countries for 17 manufacturing sectors. Secondly, using structural decomposition analysis, the paper examines statistically, whether the degree to which countries get access to sectors with above average growth in te...

In this paper, the concepts of wavelet analysis and neural networks are applied to the classification of shuttle imaging radar experiment C (SIR-C) synthetic aperture radar (SAR) data from a location in northwest China. Initially, the paper presents the visual elements of tone, texture and structural features on SAR imagery as important bases for image classification and target recognition. The...

This paper applies a new Bayesian framework laid out in Faust and Gupta (2009) for evaluating the suitability of dynamic stochastic general equilibrium (DSGE) models for the task of monetary policy analysis. The paper characterizes practical monetary policy analysis as determining how intended policy should be revised in light of the structural interpretation of incoming news. The news is defin...

this paper concentrates on investigating the effect of monetary instruments on macroeconomic variables using structural model over the period 1981- 2006. the main results of simulation show that decrease in the interest rate, increases investment but it's effect on production (gdp) is negligible. this weak effect is probably due to some factors such as, the introduction of some new project...

this study examines technical efficiency in iran's banking system using unbalanced panel data for 17 state and private banks during the 1997-2009 period. therefore, technical efficiency of banks was measured through estimating a translog cost function in the form of a panel sfa error compound model. then, the effect of underlying factors including both individual and structural (ownership/...

Regional inequality is severe in China since regional development is uneven due to various initial conditions and government policies. We employ unit root tests allowing for structural breaks to alternative inequality measures from 1952 to 2000. Empirical results indicate that (1) the regional inequality is trend stationary with structural breaks rather than follow a random walk. Thus, ignoring...
