One of the most important issues that affect the forecasting results in these models is the length of intervals. There are some studies on this issue but in most of them, length of intervals are predefined or even in some studies the interval’s length are the same. In this study we propose a model ...

In this study, we model the long-term and dynamic relationships between spot oil and exchange rates and gas prices by applying the Markov switching vector self-regression model in three regional gas markets in USA, Europe and Asia. Price behavior is analyzed using Bayesian estimation to take into account the transition from an existing relationship and the delayed and recurring effects of pric...
Portfolio selection process is a subject focused by many researchers. Various criteria involved in this process have undergone alterations over time, necessitating the use of appropriate investment decision support tools. An optimization approach used in different sciences is using meta-heuristic algorithms. In the present study, using Water Cycle Algorithm (WCA), a model was introduced for sel...
Short-term and long-term relationship between exchange rate, oil price and spot gas price of three regional gas markets was investigated using and estimating the Vector Autoregressive model. There is a significant and long-term relationship between variables.Short-term interactions of variables with Granger causality test One-year interaction of variables with intervals of one to twelve months ...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
Through the history and since 1933, the Iranian rial has declined from 11.2 rials per dollar to almost 8600 rials per dollar today in the parallel or black market.
