A model of the servomechanism used for high-powered actuators in mechanical systems consists of a position feedback loop around the cascade connection of a memoryless saturation function with an integrator with a large time constant. The saturation function in the servomechanism has a linear high gain characteristics for a small input and so the equivalent time constant of the actuator servomec...

In this study, yield-water and profit function was used to obtain water demand function in agriculture sector. The results showed that the ratio of actual to potential Evapotranspiration had positive, significant effecton the ratio of actual to potential yield for wheat and barley. Also, square ratio of actual to potential Evapotranspiration had negative, significant relationship. After estimat...

I n this study, the Regional Input- Output Structural Decomposition Analysis (I-O SDA) is used to investigate the effects of technological changes on employment in Sistan and Baluchestan Province of Iran during 2006-2011. This paper develops the SDA method to decompose the technological change from two viewpoints of supply and demand for intermediate inputs in each sector. These chan...

t his study investigates the factors affecting the demand for new residential buildings in urban areas of iran during 1976-2010. the demand function for new residential buildings in urban areas was estimated and then the existence of a long-run relationship among variables of this function was studied using the bounds testing of the autoregressive distributed lag co-integration procedure. the t...

Two-thirds of education production function studies relating learning to school and parental inputs also include parental income. This confounds demand and production functions, since in demand functions income determines the school inputs used in the production function. In a comprehensive review of the literature, we show that with this misspecification significantly positive school input coe...
