Ni nanopowders were sintered by a field-assisted sintering technique (FAST). The influence of heating rate from 90 to 1100 â—¦C/min on densification and final grain structure of sintered Ni was studied. A moderate heating rate was found to be beneficial for the densification of Ni...

Overestimated forecasts of the impact of new policy, which over-predict policy success, are a well-known problem. Studying the effects of forecasting methods on potential biases may help modelers, planners and policy makers better use the forecasting tools. This paper addresses overestimation of...

Rising demand for parking at suburban transit stations, such as the Bay Area Rapid Transit (BART) District in California, necessitates strategies to manage traveler demand. To better manage parking supply, researchers implemented a smart parking field test at the Rockridge BART station from 2004...

This report presents an evaluation of the first transit-based smart parking project in the U.S. at the San Francisco Bay Area Rapid Transit (BART) District station in Oakland, California. The report begins with a review of the smart parking literature; next the smart parking field test is...

The UC Davis IGERT grant for Transportation Technology and Policy (TTP) began October 1, 1998 and officially concluded September 30, 2005, although no students were funded in its seventh and final year. The TTP theme of the grant was shared by the degree-granting program of the same name (the...

This manuscript on lifecycle analysis (LCA) of biofuels for transportation has three major parts: * I. An analysis of greenhouse-gas emissions from biofuels, estimated using the Lifecycle Emissions Model (LEM). * II. A review of recent LCAs of biofuels. * III. A comprehensive conceptual...

Due to increases in congestion, transportation costs, and associated environmental impacts, a variety of new enhanced transit strategies are being investigated worldwide. The transit-oriented development (TOD) concept is a key area where several enhanced transit strategies can be implemented....

Carsharing provides users access to a shared vehicle fleet for short-term use throughout the day, reducing the need for private vehicles. The provision of on-street and public off-street parking dedicated to carsharing is an important policy area confronting public agencies. As of July 2009,...

The fuel cell powered vehicle is one of the most attractive candidates for the future due to its high efficiency and capability to use hydrogen as the fuel. However, its relatively poor dynamic response, high cost, and limited life time have impeded its widespread adoption. With the emergence of...
