Proton Exchange Membrane fuel cell (PEMFC) technology for use in fuel cell vehicles and other applications has been extensively developed in recent decades. Besides the fuel cell stack, air and fuel control, and thermal and water management are major challenges in the fuel cell vehicle...

The United States is experiencing dramatic growth in commercial vehicle truck travel on our nation's roadway system as well as critical shortages in truck parking. California ranks first in the nation's overall (private and public) commercial vehicle parking shortage. Recent estimates of the...

The University of California Information Center for the Environment (ICE) and the California Department of Transportation (Caltrans) are developing a GIS-based analytical framework to improve the effectiveness of biological mitigation throughout California. Goals include incorporating the best...

Increasingly, public transit authorities are harnessing advances in sensor, payment, and enforcement technologies to operate parking facilities more efficiently. In the short term, these innovations promise to enhance customer parking experiences, increase the effective supply of existing...

Recent studies on real-world automobile emissions measurements have not adequately addressed the question of whether driving style affects emission levels. In this study, we hypothesized that given the same experimental conditions and a random selection of drivers, the variability associated...

Short rotation woody crops (SRWC) such as hybrid poplar are potential feedstocks for cellulosic derived biofuels. The ability to accurately predict the growth and biomass yields of SRWC under various environmental conditions is important for predicting economic performance and...

In recent years interest has been growing in using fuel cell powered auxiliary power units (APUs) to reduce idling in line-haul trucks. Demonstrations of this technology have been constructed at universities and within industry, each with its own advantages and disadvantages. Invariably, in...

A brief review of some studies undertaken reveal that direct relationships between DCP penetration and R-value are not reliable for general use in California. Limited studies appear to have been carried out and any relationships developed are based on very small samples that have significant...
