Recent years, High-Speed railway has become a hot topic of railway development. Many countries in the world have built relatively complete high-speed railway networks.Each of them enjoys its own efficient traffic organization system and method, as well as a theory of station distribution layout. Based on the railway traffic conditions in China, the designer is adopting special procedure for bu...
abstractthe reform of energy subsidies has affected economic growth, as a result of household and firms’ behavior. however, despite the energy consumption and economic growth decrease in the short run, it is expected that economic growth will increase as a result of an adjustment in economic agents’ behavior over the mid- and long-terms. as is appropriate with these changes, energy consumption ...
Fuel pricing is one of the key issues in energy consumption management, which plays an important role in the proper use of energy resources. In this area, effective decision- and policy-making can, in addition to managing fuel consumption, also prevent drastic price changes in the energy market. Various factors such as fuel supply, demand, production, transportation and inventory costs, supply ...
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-...
this paper investigates the possibility of both linear and nonlinear effects of energy consumption on economic growth in iran, using data for the period of 1959–2007 based on threshold regression. some previous studies support the view that energy consumption may promote economic growth. however, the conclusion drawn from this study suggests that such relationship exists only where there is a l...
considering importance and the role of forecasting water consumption in water resources management and implementing appropriate short- and long-run policies in order to optimize water demand, therefore, this study aims to provide a model for predicting the water consumption via box and jenkins method. to this end, monthly data for the domestic and agricultural water consumptions of tehran provi...
Industries are one of the main sources of pollution in the world. Besides, the levels of energy resources consumption including water, electricity, and fossil fuel are very different among industries. On the other hand, Iranian government pays a large amount of energy subsidy to manufacturing units. Because of it, the government wants to know which of manufacturing industries are efficient, pro...

We consider the problem of an optimal consumption strategy on the infinite time horizon based on the hyperbolic absolute risk aversion utility when the interest rate is an Ornstein-Uhlenbeck process. Using the method of subsolution and supersolution we obtain the existence of solutions of the dynamic programming equation. We illustrate the paper with a numerical example of the optimal consumpti...
