the input - output framework is applied in this study to analyse the change, in the use of labor input. on the basis of input-output tables sectors of the economy are specified according to the degree of their interdependences. backward and forward employment linkages can he calculated. the sectors then are classified according to their total (direct and indirect) employment linkages. through a...

abstract the aim of this study is of the effect of structural changes in higher education on changes of output in sistan and baluchestan province using structural decomposition analysis (sda). the input-output tables of this region for the period 2006-2011 have been employed as the database of the model. the structural changes were decomposed into two factors: changes in share of specific secto...

This study investigated the role of interactive output tasks in developing EFL learners’ vocabulary knowledge. The participants were 103 elementary female Iranian EFL learners who were randomly divided into three groups: input-only, input-output-no-interaction, and input-output-interaction. After all participants took a placement test and a vocabulary pretest, the input-only group was exposed t...

In this paper, we quantize electromagnetic field in, lossy, dispersive and anisotropic magnetodielectric media by using phenomenological approach. We obtain quantum input– output relations for anisotropic multilayer metamaterials. As an application of our approach, we investigate the dissipative and anisotropic effects of an anisotropic magnetodielectric slab on the quantum properties of incide...

An analytical model for two-pass optical amplifier with arbitrary beams overlap has been developed which generalized the classical theory of Frantz-Nodvik for single pass amplifier. The effect of counterpropagating beams on gain and output energy fluence included in the model. Moreover, the appropriate limiting relations for two special cases of weak input signal and saturation state of the amp...

This paper addresses the experimental identification of a servo actuator which is used in many industrial applications. Because the system consisted of electrical and mechanical components, the behavior of the system was nonlinear. In addition, the under load behavior of this servo was different. The load torque was considered as the input and a two input-one output model was presented for t...

In this study, a three–layer artificial neural network (ANN) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. A total of 455 data points were collected from 13 data sources to develop the ANN model. Superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of ...
