Indoor Nitrogen Oxides
Nitrogen monoxide (NO) and nitrogen dioxide (NO2) are gases produced by hightemperature combustion through reactions between nitrogen and oxygen. Both nitrogen in fuel and nitrogen in the air can participate in the reactions. Formation of NO can be followed by further oxidation into NO2 in the atmosphere. NO2 is the most toxic of the nitrogen oxides (grouped generically as NOx) and it is very i...
متن کاملPrediction of Indoor Nitrogen Oxides Concentration
Indoor air is mostly contaminated from the use of gas for heating and cooking appliances. It is well known that the oxide of nitrogen production in the combustion products is the process that not been exactly described so far on all variables which are connected with its production. The comprehensive analysis of indoor air nitrogen oxides pollution show that extent of indoor air level exposure ...
متن کاملContribution of indoor and outdoor nitrogen dioxide to indoor air quality of wayside shops.
Indoor nitrogen dioxide (NO₂) concentration is an important factor for personal exposure despite the wide distribution of its sources. Exposure to NO₂ may produce adverse health effects. The aims of this study were to characterize the indoor air quality of wayside shops using multiple NO₂ measurements, and to estimate the contribution of outdoor NO₂ sources such as vehicle emission to indoor ai...
متن کاملIndoor-Outdoor Image Classification
We show how high-level scene properties can be inferred from classiication of low-level image features, speciically for the indoor-outdoor scene retrieval problem. We systematically studied the features: (1) his-tograms in the Ohta color space (2) multiresolution, simultaneous autoregressive model parameters (3) coef-cients of a shift-invariant DCT. We demonstrate that performance is improved b...
