Environmental conditions have a significant effect on the performance of flexible pavements. External factors such as precipitation, temperature, freeze-thaw cycles, and depth to water table play a key role in defining the extent of the impact the environment effects on pavement performance. All types of pavement distress are either caused or aggravated by the environmental factors. Up until now, pavement design in Iran is done according to the AASHTO 1993, which is based on methods that have evolved from the AASHTO Road Test that was conducted at one specific geographic location. The newly released Mechanistic Empirical Pavement Design Guide (MEPDG) by the addition of climatic input makes... 

This thesis analyzes the behavior of inflation in the Iranian economy by introducing a micro-founded model of monetary policy. The model predicts a direct relationship between inflation and oil export revenues in the oil dependent economy of Iran. This theory driven claim is verified empirically, and test results tend to confirm a meaningful relationship between inflation and Oil export data in Iran. Based on results attained from the micro-founded model, an augmented SVAR model is proposed for estimating underlying inflation in the Iranian economy. The proposed model is found to render better results than the conventional models used for estimating underlying inflation. Moreover it is... 

The growing requirements for renewable energy production lead to the development of a new series of systems, including wave and tidal energy conversion systems. Due to their sensitivity and the impact of the aggressive marine environment, the selection of the most adequate location for these systems is a major and very important task. Several factors, such as technological limitations, environmental conditions, administrative and logistic conditions, have to be taken into account in order to support the decision for best location. The aim of the present study is to provide an Atlas of IRAN Offshore Renewable Energy Resources (hereafter called ‘the Atlas’) to map out wave and tidal resources... 

An important characteristic of sea waves is their high energy density, which is the highest among renewable energy sources. Many different types of wave-energy converters of various categories have been proposed yet. In this thesis the performance of a novel wave energy converter (WEC) is studied.

Iranian Power industry has undergone fundamental changes since deregulation started in 2003. Currently, bulk trade of electricity in the industry is mainly conducted through a day ahead wholesale market, representing over 98 percent of the exchange of electricity within the grid. Although the current market regime is under operation for over 4 years, several political, cultural and operational obstacles have hindered effective evolution of the restructuring process. Low political support from privatization of the industry assets backed by lack of confidence and trust in market economies in general, and low economic incentive of the market players has slowed down formation of an effective...

This research aimed to investigate the relationship between household poverty and the gender of the head in the Iranian households. The self-reported gender of the head of household (FHH), underestimates the rate of poverty in female- head households (FHH). The self-reported gender of the head of household considers, conventionally, a family as male-head, even if the man of the family is incapable of making money. In much of these families the wife is the sole income holder even though she is not recognized as the head. In this study, a definition for household headship is introduced, which considers head of household the one who provides more than 50% of household income. Using household’s... 

In this research the risk of oil price for Iran and Opec basket is studied. Several methods in order to estimate Value at Risk (VaR) such as Standard Historical Simulation, Historical Simulation with Autoregressive Forecast, Historical Simulation with moving average forecast, and ARMA are examined. The experiment is performed based on daily oil prices, from January 2005 to December 2009. The data is divided into two smaller time periods. The first, from 2005 to 2008, was used to estimate the model coefficients. The second part of data, i.e., the data gathered in 2009, was used for forecasting purposes. The result of experiment show that Historical Simulation with Autoregressive Forecasts... 

In this thesis, with a review on policy simulation and economic reform analysis literature, we design a suitable method to analyze the effects of monetizing energy carriers subsidy on welfare criteria of Iranian households. The selected method is limited general equilibrium that needs demand estimates of goods, services and energy. In firs step,based on 13 years of data on “Iranian Households’ Expenditures and Income” surveys, data are provided as a pseudo-panel. Demand equations are estimated using “Seemingly Unrelated Regressions” for panel data, and elasticities are calculated. In the next step, we evaluated the equivalent variation and equivalent gain measures in each price scenarios.... 

One of the major aims of privatization is increasing the productivity by transferring ownership to private sector. We would like to estimate this effect in selected state –owned firms. Analysis the productivity effect of privatization of Iranian firms that were initially state-owned will show the requirement of needy policies in management field of privatization to ratify and run the privatization policy faster base on academic estimate. We analyze the productivity effect of privatization using time series and cross search data (panel data) for 21 selected initially state-owned firms that are privatized in different industry with several observations pre and post privatization. Our goal is...

On the contrary to common explanations of fertility transition in the Iraninan Economy there has been a growing human capital without decline of fertility for some decades followed by a rapid fall in fertility without a higher growth of human capital during the next decades. Accounting for these facts we propose a new link between subsidies financed by exogenous oil revenue and the evolution of fertility and human capital. While the educational subsidy accelerates the growth of human capital, the presence of financial subsidies keeps fertility from declining. Then, fertility declines with sizeable delay but sharply because (i) high fertility in first generations implies a growth rate of... 

The main purpose of my research is to present a predictive E-Commerce plan for Iran. For many people the term "electronic commerce" means shopping on the part of the Internet called the World Wide Web, but other technologies such as wireless transmissions on mobile telephone and personal digital assistant devices are also included. In our thesis the term Electronic Commerce or (E-Commerce) is used in its broadest sense, and includes all business activities conducted using electronic data transmission technologies. In Iran e-commerce has achieved an important role and is facing remarkable acceptance in trade operations, therefore my study focuses on the development of E-Commerce model in... 

This research uses the new approach of Son (2003) for the decomposition of poverty in Iran into three separate components of growth, inequality and population effects during 2001 to 2007 and meanwhile uses the integration of microeconomic and macroeconomic data together to increase the accuracy of the results. The main question of this research is to determine the orientation of development strategies for alleviation of poverty in Iran, which could be either growth-oriented or inequality-oriented ones. The resultes suggest that the former has always been pro-poor in Iran and has had the most dominant effect. Therefore, in order to decrease the poverty in Iran in the future, there should be... 

In this piece of work, a gravity model is suggested as Iranian non-fuel export model to OIC countries. The most important results out of this model are the acquired coefficients of two variables, namely “ECO membership” and “Economic and Trade Freedom of Importer”. At first, we expected that for importer, being a member of ECO would increase the amount of trade with iran. Surprisingly, this is not what we see in a model. In fact, as ECO has not achieved any tangible success in increasing trade between its members, eastern Asian Muslim countries has become an important trade partner for iranians. This result is compatible with other pieces of researches about ECO. “Economic and Trade Freedom... 

This project shows the flow of implementing a 5s Program into a factory. From it’s first step by studying current situation until the last step implementing and monitoring the results. Manufacturing companies have a growing, market-driven need to adopt World Class operating technologies, including lean manufacturing 5S principles. Understanding the program's importance and knowing how to get started are the most important steps. In Iranian economic environment it is always hard to convince any top management to invest on methodologies like TPM. The reason behind this is that there are very few examples of companies with successful implementation of these methodologies. Since management...

Energy industries in many countries have initiated the process of privatization. Restructuring of energy systems is usually started with dividing the vertically integrated national systems into regional companies. Due to the geographical dimension of energy systems and natural monopoly in many activities, the process of privatization has started with segmentation of the vertically integrated national systems into regional companies. Thus, regional independent companies are formed that include a collection of producers and consumers of energy in their geographic area. These regional companies are economic entities who are pursuing a policy of maximize profit. On the other hand, exchange of...
