this paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. with regard the increasing importance of lng carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...

This study aims at comparing the economic relations of Japan with Iran and with Saudi Arabia. The comparison of these two relations is important as Iran and Saudi Arabia are leading exporters and Japan is a large importer of crude oil in the world. After a brief overview of the history of these two relations, the criteria of trade complementarity, i.e. Trade Potential Naive Assessment, Cosine M...

Regulators and firms often use incentive schemes to attract skillful agents and to induce them to put forth effort in pursuit of the principals’ goals. Incentive schemes that reward skill and effort, however, may also punish agents for adverse outcomes beyond their control. As a result, such schemes may induce inefficient behavior, as agents try to avoid actions that might make it easier to dir...

The Ellenburger Group of the West Texas Permian Basin is part of a Lower Ordovician carbonate platform sequence that covers a large area of the United States. During the Early Ordovician, the Permian Basin area was located on the southwest edge of the Laurentia plate between 20° and 30° latitude. The equator crossed northern Canada, situating Texas in a tropical to subtropical latitude. The are...

Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher co...

in this paper, the performance of a natural gas hcci engine is studied through a thermodynamic model including detailed chemical kinetics. it is shown that as hydroxyl radical has important effects on natural gas combustion, it is possible to quantify soc with hydroxyl concentration variations. meanwhile the influence of using formaldehyde as an additive on the engine characteristics has been i...
