This paper aims to investigate the direction of causality between economic growth, energy consumption and trade openness in case of Iran for the period 1967–2012. We apply the newly developed combined cointegration test proposed by Bayer and Hanck (2013). Vector Error Correction Model (VECM) is applied to determine the direction of causality between these three variables. The result of Bayer-Ha...

This study aims to estimate the function of copper consumption using the Johansen approach in time series data, between 1991-2011 in Iran. The literature review of specialized consumption and demand functions shows factors influencing the consumption of copper including copper price variables, aluminum price as a substitute commodity, oil price as a complementary commodity, and industrializatio...

vt(mt;χt) = u(χt(mt)) + β Et[vt+1((mt −χt(mt))R+ yt+1)] (1) vt(mt;χt) = u(χt(mt)) + δβ Et[vt+1((mt −χt(mt))R+ yt+1)] (2) Notice that these functions are well defined for any consumption function χt(mt) that is feasible; they are not Bellman equations because they do not assume that the consumption function χt is optimal. For example, these functions would be well defined for χt(mt) = mt, or for...

Background: Healthy dietary habits are known as a key factor for improving brain functions and cognitive ability in children and adolescents. The goal of this study was to evaluate the association of healthy food consumption with mental health in Iranian children and adolescents.Materials and Methods: Data were obtained from the fourth national school-based surveillance survey entitled CASPIAN-...

Computer-aided design (CAD) tools are frequently employed to verify the design objectives before the fabrication of an integrated circuit. An important circuit parameter that requires accurate characterization is the power consumption due to the strict constraints on the acceptable power envelope of integrated systems. Circuit simulators typically provide built-in functions to measure the power...
