Environmental Assessment of Plug-in Hybrid Electric Vehicles In the most comprehensive environmental assessment of electric transportation to date, the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC) are examining the greenhouse gas emissions and air quality impacts of plug-in hybrid electric vehicles (PHEV). The purpose of the program is to evaluate th...

The transportation of hydrogen is a weak link in the large-scale development energy industry. Injecting into natural gas pipeline network for an efficient way to achieve large-scale, long-distance, and low-cost hydrogen. Hydrogen can lead embrittlement pipelines cause safety incidents if are not mixed uniformly. Therefore, it necessary study blending process uniformity gas. In this study, three...

In retrospect, it is inevitable that the business world will take notice of experimental economics. Laboratory experiments have become an increasing important tool in economics to study behavior, test policies and provide information to design better mechanisms. On one hand, pioneers such as Vernon Smith and Charles Plott have provided the link between economics theory and actual economics beha...

We give a short introduction to mixed-integer nonlinear programming from a linear programming perspective. In this approach, all nonlinearities are approximated by linear inequalities and spatial branching, such that in the end only linear programs remain that can be solved efficiently. We present two transportation applications from rather different fields: Railway freight on one side, and nat...

Several respected experts recently declared victory in the deregulation of telecommunications, favorably comparing changes in the industry to the 1970s, when Gerald Ford and Jimmy Carter eliminated regulations on transportation and oil and gas industries. Compared to that wave of deregulation, however, declaring victory in telecommunications is premature. Regulatory reform in communications has...
