Imagine a world where government regulation of gasoline, justified by scarcity of supply, allowed 20% of the gasoline in the U.S. to be used for farming; 20% for manufacturing; 20% for home use; 20% for government; and another 20% held in reserve for future potential government uses. In this world, prices would regulate the use of gasoline within each sector, but consumers would pay vastly diff...

This paper applies artificial neural networks to forecast gasoline consumption. The ANN is implemented using the cross entropy error function in the training stage. The cross entropy function is proven to accelerate the backpropagation algorithm and to provide good overall network performance with relatively short stagnation periods. To forecast gasoline consumption (GC), the ANN uses previous ...

Since 1999, gasoline prices in California, Illinois and Wisconsin have spiked occasionally well above gasoline prices in nearby states. In May and June 2000, for example, gasoline prices in Chicago rose twenty eight cents per gallon to $2.13, while prices nationally rose only nine to $1.73. Several qualitative studies identify unique gasoline formulations in California, Illinois and Wisconsin a...

Particulate matter of vehicle exhaust is known to contain carcinogenic compounds such as polycyclic aromatic hydrocarbons (PAH) and is suggested to increase lung cancer risk in humans. This study examines the differences in diesel and gasoline-derived PAH binding to DNA in a human bronchial epithelial cell line (BEAS-2B). Particulate matter (PM) of gasoline exhaust was collected from passenger ...

Introduction Gasoline is a complex solution of different hydrocarbons. Naturally occurring petroleum contains aromatic hydrocarbons, a class of unsaturated hydrocarbons that includes benzene, toluene, ethylenzene, and xylene (collectively known as BTEX). Since the EPA banned lead additions to gas in 1973, aromatic hydrocarbons were added to increase the octane concentration, thereby maximizing ...

The Environmental Protection Agency introduced Reformulated Gasoline (RFG) requirements as a measure to reduce emissions from gasoline-powered vehicles in certain geographic areas. The EPA developed models for predicting emissions as a function of gasoline properties and established statutory baseline emissions from a representative set of gasolines. RFG is a key driving force for investment in...
