Abstract: Quantitative methods for characterizing both variability and uncertainty are applied to case studies of nitrogen oxides

Abstract: This paper explores methods for analyzing onboard mass emissions data and developing modal models on the basis of case study examples for nine selected nonroad construction vehicles. Data for these vehicles were obtained ...

Abstract: A new performance model of the externally fired combined cycle (EFCC) is implemented in ASPEN (Advanced System for Process ENgineering), a chemical process simulator. The model accounts for interactions within and between ...

Abstract: Conventional evaluation approaches for complex technologies, such as gas turbine systems, typically use process simulators for modeling, which are usually complicated and time-consuming. In order to facilitate policy ...

Abstract: Technological innovation in emissions control of acid rain precursors has made possible increasingly stringent control requirements for coal‐fired power plants. A key challenge for potential process adopters is evaluation ...

Abstract: Real-world vehicle fuel use and emission rates are sensitive to road grade. There is a need for a practical method for measuring road grade in combination with on-board measurement of vehicle activity, energy use, and ...

Abstract: Commercial construction operations are heavy users of nonroad equipment and diesel engines. These engines are large contributors of carbon dioxide (

Abstract: Nonroad construction vehicles and equipment powered by diesel engines contribute to mobile source air pollution. The engines of this equipment emit significant amounts of carbon monoxide, hydrocarbons, nitrogen oxides, and ...
