Abstract
In this research , the effect of Iran’s government’s expenditures on private sector’s investment during the period between 1971 to 2005 has been investigated . The results of the Cointegration vectors derived from the johansen method indicates that government investment expenditures have complimentary effects on the private investment expenditures while the government consumption expenditures have competing effects

Abstract
In this paper the principles of simultaneous measurement of three orthogonal force vectors Fx, Fy, Fz and three orthogonal torque vectors Mx, My, Mz to design a six axis force/torque sensor are considered. At first, a new index (η) for a qualitative comparison of six-axis force/torque sensors is proposed and then, cross-coupling error of several sensors presented in previous studies is evaluated and compared by using the new index. In the following, a systematic method for designing the six-axis force/torque sensor is described using numerical optimization procedure. This method is based on interactive interface between the SQP algorithm created in MATLAB and FEM analysis in ANSYS software. The geometry of sensor structure is selected to be a modified Maltese cross type. Principle cross-coupling error is chosen as the objective function to optimize four geometrical design variables of the sensor structure. Also, strain gauge sensitivity, maximum applied stress and geometric sizes of the sensor structure as constraints are formulated in problem. Results show that principle cross-coupling error of the optimal sensor design is less than 1.49% with a high moment to force specification (0.1 N.m/N).

Abstract
The main objective of this research is to investigate the impact of financial structure on the Iranian economic growth volatility by applying GARCH & ARDL methods using quarterly data over the 1991-2015 period. The results indicate that financial development and financial structure have negative and positive effects on the economic growth volatility in Iran, respectively. The results reveal that financial structure in Iran is facing with several challenges, so that regardless of negative impact of financial development on economic growth volatility, the financial structure leads to economic growth volatility. In addition, oil revenues, government final consumption expenditure and capital formation have significant and negative relationships with economic growth volatility in the period under study.

Abstract
Expansion, utilization and distribution of potential economic opportunities among people have important impacts on the prosperity of each country. Simon Kuznets was the first researcher who systematically examined the relationship between economic growth and income distribution based on the statistical data. According to Kuznets, income inequality will decrease by economic growth in the long term. Therefore, economists focused on economic growth in order to reduce income inequality. However, the Kuznets hypothesis was faced with a serious challenge by publication of Piketty's “Capital” in the twenty-first century. Since, according to Piketty, not only income inequality has not diminished, but also it has increased unprecedentedly in the advanced stages of economic growth and development. In this regard, the aim of this study is to investigate the Thomas Piketty's hypothesis based on the statistical evidence of Iran by using the ARDL econometric method during the period 1975-2015. The results confirm Thomas Piketty's hypothesis according to statistical evidence of Iran. In addition, the effect of non-oil GDP on income inequality is negative and significant, but the impact of oil revenues is positive and significant. War has also led to increased income inequality.
