Iran’s Economic Strategies to Participate Japan’s LNG Market by Using Game Theory
, M.Sc. Thesis Sharif University of Technology ; Maleki, Abbas (Supervisor)
Abstract
Iran has the second largest gas reserves in the world with huge gas reserves about 32 trillion cubic meters. The expansion of gas exports in recent decades has been accompanied by liquefied natural gas exports, with the LNG industry growing rapidly due to the inability to export gas via pipeline to distant markets. The expansion of the LNG industry around the world, there have been various markets for this product that the Southeast Asian market being the largest market for this product and Japan is the largest importer in this sector.Specific mechanisms of the Japanese market, which have separated it from the rest of the LNG importing countries, are the extension of long-term contracts for...

Abstract
The discontinuous Galerkin method is used to solve the non-linear spherical shallow water equations with Coriolis force. The numerical method is well-balanced and takes wetting/drying into account. The two fold goal of this work is a comparative study of dynamic and static tsunami generation by seabed displacement and the careful validation of these source models. The numerical results show that the impact of the choice of seabed displacement model can be significant and that using a static approach may result in inaccurate results. For the validation of the studies, we consider measurements from satellites and buoy networks for the 2011 Tohoku event and the 2004 Sumatra–Andaman tsunami. The...

Abstract
Abutments of concrete arch dams are usually crossed by several joints, which may create some rock wedges. Abutment stability analysis and controlling the probable wedge movements is one of the main concerns in the design procedure of arch dams that should be investigated. For decades, the quasi-static method, due to its simple approach, has been used by most of dam designers. In this study, the dynamic method is presented and the obtained time history of sliding safety factors is compared with the quasi-static results. For this purpose, all three components of Kobe (1979) and Imperial Valley (1940) earthquakes are applied to the wedge, simultaneously, and the magnitude and direction of wedge...
