United States power in Persian Gulf has risen since the end of Second World War. Dividing U.S. presence in the Region into the Cold war and post-Cold war era, the principle policy in first period was narrowing the impact of Soviet Union in the Region and in latter, Access to Persian Gulf region’s oil and controlling the major threats which can disrupt the flow of oil to global energy market. Fo...

Due to the rapid development of the global economy, fossil oil is widely used, leading to its depletion and gradual deterioration of the global environment, including global warming, the greenhouse effect, fog, and haze. Therefore, many researchers have been interested in studying alternative fuels in an attempt to develop an eco-friendly fuel to replace traditional fuel and solve the above env...

We study the solution of non-convex, pessimistic bi-level problems. After providing several motivating examples, we relate the problem to existing research in optimisation. We analyse key properties of the optimisation problem, such as closedness of the feasible region and computational complexity. We then present and investigate a semiinfinite solution approach that solves ǫ-approximations of ...

Climate simulations performed with general circulation models (GCMs) are widely viewed as the principal scientific basis for developing policies to address potential future global change scenarios (e.g. global warming, ozone depletion, changes in land use, etc.). Hence, there is a compelling need to systematically improve the performance of GCMs in simulating the present climate, and thereby to...
