Abstract
Fog harvesting is an unconventional source of water that can be used in some regions with water scarcity to overcome water shortages. The most commonly used collectors are meshes which have intrinsic limitations, the most important of which are clogging and aerodynamic deviation of droplets around the wires. Here, three techniques are compared and combined to overcome these limitations, i.e., replacing the mesh with an array of vertical wires, addition of a hydrophobic layer to the wires, and forcing the ionized droplets to move toward the wires by applying an electric field. The combination of these techniques was found to result in higher fog harvesting efficiency compared to each...
Countries Short Term Interest Rates Response to u.s. Monetary Policy Shock, Their Explanatory Elements and Type II Price Puzzle
, M.Sc. Thesis Sharif University of Technology ; Barakchian, Mahdi (Supervisor)
Abstract
There have been numerous papers worked on the effect of U.S. monetary policy on other countries macroeconomic variables; considering U.S. important role in the world economy. However, few papers focus on foreign countries monetary policy reactions to U.S. monetary policy. The main purpose of this dissertation is to find out how foreign countries policy makers react to U.S. monetary policy. In order to answer this question, we consider the effect of exogenous monetary policy shock on other countries’ short term interest rates. The second part of the dissertation focuses on which elements can explain the differences in countries’ monetary policy reaction. At last, we consider the effect of...
