The University of Denver conducted a five-day remote sensing study in the Chicago area in the fall of 1997. The remote sensor used in this study is capable of measuring the ratios of CO, HC, and NO to CO 2 in motor vehicle exhaust. From these ratios, we calculate the percent concentrations of CO, CO 2 , HC and NO in motor vehicle exhaust which would be observed by a tailpipe probe, corrected fo...
The Transportation Research Forum, founded in 1958, is an independent, nonprofit organization of transportation professionals who conduct, use, and benefit from research. Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...
word count: 230 TRB 2006 Annual Meeting CD-ROM Paper revised from original submittal. Barth/Collins/Scora/Davis/Norbeck 2 ABSTRACT In recent years, automobile manufacturers have been producing gasoline-powered vehicles that have very low tailpipe and evaporative emissions in order to meet very stringent certification standards set by the U.S. Environmental Protection Agency and the California A...
Currently, from the statistical analysis of accidents at home and abroad, the number of automobile defects and the resulting automobile accidents are very large. Obviously, the automobile defects have become one of the main factors affecting traffic safety, and risk assessment as an automobile key technical defect of risk management, the elimination of defects and reduce automobile accidents ar...
The University of Denver conducted a five-day remote sensing study in the LaBrea, California area in October of 2001. The remote sensor used in this study is capable of measuring the ratios of CO, HC, and NO to CO2 in motor vehicle exhaust. From these ratios, we calculate mass emissions per kg (or gallon) of fuel and the percent concentrations of CO, CO2, HC and NO in motor vehicle exhaust whic...
Technology forcing is a strategy where a regulator mandates a standard that cannot be met with existing technology to internalise external costs associated with the production and/or use of a product. We argue that the implementation process for these policies has a pronounced effect on how regulations affect the development and diffusion of new technologies. To examine this proposition, we loo...
This paper combines input–output analysis with non-negative matrix factorization analysis widely used in the image segmentation and attempts to find the target industrial groups (industrial clusters) in Japan that have intensive CO 2 emissions. We generalized the industrial cluster analysis proposed by Kagawa et al. (2012) to identify environmentally-important industrial clusters from the entir...
Approximately 3.2 to 3.5 million metric tonnes of DDGS are produced annually in North America (Markham, 2000; personal communication). Ethanol plants in Minnesota, South Dakota and North Dakota produce approximately 25% of this amount (850,000 to 900,000 tonnes) annually (Markham, 2000; personal communication). Most of the ethanol plants in the Minnesota-Dakota (MNDAK) region are small, farmer ...
