ublicly owned treatment works (POTWs) are beginning the process of identifying air emissions from their wastewater treatment and collection facilities. Many of these facilities will be required by local and state regulatory agencies to reduce emissions to meet air quality or health risks standards. Emissions include odors and toxic, reactive, volatile and criteria pollutants. A wide range of re...

Introduction: The national trend indicates that various provinces of Iran have experienced in attaining economic growth exclusive of parallel observing a boost in CO2 emissions. It is clear that the effects of CO2 emissions on health indicators such as death rate, infant mortality, and health expenditures have been ignored by policy makers over the last decade.   Methods: This study for ...

Almost three quarters of the hydrocarbon (HC) emissions emitted by an automobile in a typical drive-cycle are produced during the first three minutes of its operation called the coldstart period. In this paper, we propose a way to decrease cold start emissions. A Model-Based paradigm is used to aid the generation of an efficient controller. The controller is built around a mean value engine mod...

Understanding the relation between vehicle emissions and traffic control measures is an important step toward reducing the potential for global warming, smog, ozone depletion, and respiratory illness. Traffic analysts, through improved roadway design and traffic control, have the ability to reduce vehicle emissions. However, current vehicle emissions models do not allow traffic analysts to easi...

Reducing greenhouse gas emissions is now an urgent priority. Systems control theory, and in particular feedback control, can be helpful in designing policies that achieve sustainable levels of emissions of CO2 (and other greenhouse gases) while minimizing the impact on the economy, and at the same time explicitly addressing the high levels of uncertainty associated with predictions of future em...

Real driving emissions (RDE) testing is an important legislative tool to reduce the gap between type-approval and real-world of internal combustion engines. Since low fuel consumption nitrogen oxides (NOx) are conflicting objectives, setpoints a Diesel engine its exhaust-gas aftertreatment system have be optimised controlled accordingly. To this end, several authors developed so-called supervis...

The extensive and close economic linkages among different regions of China have effects not only on regional economic growth, but also on CO2 emissions and carbon leakage among regions. Taking Beijing as a study case, we constructed MRIO models for China’s 30 provinces and municipalities for 2002, 2007 and 2010, to measure the embodied CO2 emissions in the interregional trade of China on region...
