16and air-quality modelling results17indicate that residential combustion, traffic, and anthropogenic dust are the most important contributors to PM pollution in India. However, there is still a lack of quantitative understanding of the spatial distribution of these emissions and their contributions...
(Equation 9)Where Pi is predicted values by the model, and Oi are observed values from on-site measurements in the barn, and n is the number of observations. The relative RMSE is calculated by dividing the RMSE by means of the observed values. For testing the statistical significance ...
Test-to-test variability has been observed by many current testing methods, including the Federal Test Procedure, the IM240 dynamometer test, the idle test common to many Inspection and Maintenance programs, and on-road remote sensing. The variability is attributable to the vehicle, not to the ...
The US Commodity Futures Trading Commission (CFTC) Chairman Gary G. Gensler notified on November 3 that detailed regulation of financial derivatives will essentially form a critical element of a better-functioning domestic emissions trading market.

very little field testing had been done on perc machines to estimate emissions.No field testing data for inventory development purposes was available from commercially operating hydrocarbon machines.Results of the testing indicate that primary/secondary control perc machines emit an average of 50% of ...
If this unique CCC process proves as effective and affordable as Jaeger and his ESL TEK team are confident it will, it promises to be a real game changer, especially in those states where emissions testing of used cars is required. Stay tuned....
The paper outlines the legislation related to the exhaust emissions from non-road vehicles. Example test results under actual operating conditions have been presented and on this basis, conclusions have been formulated as regards the applicable testing procedures. 被引量: 3 年份: 2015 ...
Results of a survey to determine typical fireplace use patterns across the nation are summarized and used to establish a baseline wood loading pattern for laboratory testing. The sensitivity of particulate matter and carbon monoxide emissions from fireplaces to a variety of fuel and operating ...
Alternatively, roadway 20 may comprise a test lane designated for vehicle emissions testing, wherein vehicle 10 may be tested under a variety of operating conditions. In one embodiment, the RES system may comprise one or more sources of electromagnetic radiation (ER) 50 which may be used in ...
