Aerodynamics of trucks and other high sided vehicles is of significant interest in reducing road side accidents due to wind loading and in improving fuel economy. Recognizing the limitations of conventional wind tunnel testing, considerable efforts have been invested in the last decade to study vehicle aerodynamics computationally. In this paper, a three-dimensional near field flow analysis has...

Discriminators are described that quantify enhancements added to plutonium destruction and/or nuclear waste transmutation systems through use of an accelerator/fluid fuel combination. This combination produces a robust and flexible nuclear system capable of the destruction of all major long-lived actinides (including plutonium) and fission products. The discriminators discussed in this report a...

The US automobile industry has been the subject of a wide range of policy objectives, particularly within the past twenty five years. Some of these policies, for example fuel economy and emission standards, are roughly complementary, where improvements in one area can also lead to improvements in the other. However, some of these policies conflict with one another, for example, safety and fuel ...

This paper presents an overview of the economics literature on the effect of Corporate Average Fuel Economy (CAFE) standards on the new vehicle market. Since 1978, CAFE has imposed fuel economy standards for cars and light trucks sold in the U.S. market. This paper reviews the history of the standards, followed by a discussion of the major upcoming changes in implementation and stringency. It d...

The analysis of fuel economy data results in estimates of the technology utilization by manufacturer and vehicle line. The analysis employs a hierarchical Bayesian regression model with random components representing vehicle lines and manufacturers. The model includes predictor variables which describe vehicle features, such as type of transmission, and vehicle line specific measurements, such ...

Figure 1: MoS2 layered structure. As the world economy continues to expand the demand for petroleum based fuel increases and the price of these fuels rises. The rising price of fuel has another consequence: refiners tend to purchase cheaper fuels of poorer quality. These poor quality fuels contain increasing amounts of sulfur and other pollutants leading to a decline in air quality worldwide. A...
