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 procyclical behavior of public investment expenditure in OECs is one of the main channels through which the blessing of the natural resource abundance turns into a curse. The focal issue about the public investment expenditures in OECs is the misallocation and the inefficiency of these expenditures which often appear in the form of white elephants- i.e. government investment projects with large scale and high social/political prestige for the politicians implementing theme, but with negative economic return- especially in the oil booms. Moreover, the imprical evidence shows that the efficiency of public investment management in OECs is positively and significantly correlated with the...
Experimental and numerical study of the gas-gas separation efficiency in a Ranque-Hilsch vortex tube, Article Separation and Purification Technology ; Vol. 138, issue , Dec , 2014 , p. 177-185 ; Farhadi, F ; Sharif University of Technology
A brass vortextube is used to carry out a series of experiments. The main objective of the present research is to investigate the separation performances of a vortex tube (VT) for a hydrocarbon mixture. Examination is also applied to study the effects of nozzle intakes number and cold fraction on the gas species separation at specific inlet pressure 236.37 kPa in a VT with two gas mixtures (LPG as a hydrocarbon mixture and LPG-N2). A two-dimensional computational fluid dynamic (CFD) model simulation of a VT is presented. CFD code after validation is also applied to investigate the role of cold fraction and nozzle intakes number on the gas species separation. The highly rotating flow field...
The influence of public R&D and knowledge spillovers on the development of renewable energy sources: The case of the Nordic countries, Article Technological Forecasting and Social Change ; Volume 146 , 2019 , Pages 450-463 ; 00401625 (ISSN) ; Saboohi, Y ; Arasti, M ; Sharif University of Technology

Energy innovation is a key requirement to limit global warming and tackle climate change in the years to come. A better understanding of the public R&D mechanism is likely to improve allocation of resources for energy innovation. Thus, the present paper evaluates the impacts of public R&D and knowledge spillovers on the development of renewable energy sources. To achieve this goal, knowledge flow has been modeled as a function of public R&D expenditures, cumulative knowledge stocks and knowledge spillovers. To show the application of the model, the Nordic countries as one of the pioneers in renewable technologies have been chosen. Results show the cumulative knowledge stock will increase to...
Energy-efficient fast configuration of flexible transponders and grooming switches in OFDM-based elastic optical networks, Article Journal of Optical Communications and Networking ; Volume 10, Issue 2 , 2018 , Pages 90-103 ; 19430620 (ISSN) ; Pakravan, M. R ; Sharif University of Technology

We investigate the problem of energy-efficient resource allocation constrained to quality of service and physical requirements in orthogonal frequency division multiplexing (OFDM)-based elastic optical networks and propose a fast two-stage algorithm to solve it. The first stage of the proposed algorithm deals with routing, traffic grooming, and traffic ordering and mainly aims at minimization of the number of deployed optical amplifiers and transponders. We provide an integer linear program for routing and traffic grooming and propose a heuristic procedure, which yields its near-optimum solution in a shorter runtime. In the second stage, we optimize transponder parameters to minimize total...
Past, present, and future of global health financing: a review of development assistance, government, out-of-pocket, and other private spending on health for 195 countries, 1995–2050, Article The Lancet ; Volume 393, Issue 10187 , 2019 , Pages 2233-2260 ; 01406736 (ISSN) ; Cowling, K ; Micah, A.

Background: Comprehensive and comparable estimates of health spending in each country are a key input for health policy and planning, and are necessary to support the achievement of national and international health goals. Previous studies have tracked past and projected future health spending until 2040 and shown that, with economic development, countries tend to spend more on health per capita, with a decreasing share of spending from development assistance and out-of-pocket sources. We aimed to characterise the past, present, and predicted future of global health spending, with an emphasis on equity in spending across countries. Methods: We estimated domestic health spending for 195...
Studying the effect of kinematical pattern on the mechanical performance of paraplegic gait with reciprocating orthosis, Article Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine ; Volume 226, Issue 8 , 2012 , Pages 600-611 ; 09544119 (ISSN) ; Farahmand, F ; Salarieh, H ; Sharif University of Technology
Paraplegic users of mechanical walking orthoses, e.g. advanced reciprocating gait orthosis (ARGO), often face high energy expenditure and extreme upper body loading during locomotion. We studied the effect of kinematical pattern on the mechanical performance of paraplegic locomotion, in search for an improved gait pattern that leads to lower muscular efforts. A three-dimensional, four segment, six-degrees-of-freedom skeletal model of the advanced reciprocating gait orthosis-assisted paraplegic locomotion was developed based on the data acquired from an experimental study on a single subject. The effect of muscles was represented by ideal joint torque generators. A response surface analysis...
