Upgrading air filters in a number of Texan buildings not only improved indoor air quality, it also helped make maintenance easier – and secured a US property management company a clean air award in the bargain.doi:10.1016/S0015-1882(07)70026-5Anonymous...
Air Quality Index (AQI) represents the quality of air present around us. The presence of contaminants in the air leads to air pollution.
In the process of rapid urbanization, the problems of air quality and urbanization quality become the focus of the attention. The coordination formula was introduced to calculate the coordinated degree between air quality index and urbanization quality index based on the urbanization quality index from...

However, the water pollution regulations had no observable effect. Overall, these results contradict the conventional wisdom that environmental quality is a deterministic function of income and underscore the role of institutions and politics. 展开 年份: 2011 ...
(height, diameter, plume velocity, and plume temperature) applying the Holland formula33, using ambient temperature and wind speed from the air quality model’s atmospheric layer that corresponds to the emission source’s stack height and location, and ambient pressure that we calculate as a ...
However, an ANN is unable to present a clear formula for the forecasting model. SVRs are statistical models that are presented after ANNs and also employed to analyze pollution indexes (Ortiz-García et al., 2010, Yeganeh et al., 2012, Lu and Wang, 2008). The popular ANNs and SVRs ...
The SVM model parameters include: kernel function, penalty coefficient, regularization parameter and accuracy. There are five kernel functions: linear, poly, rbf, sigmoid and pre-computed. This paper choose linear kernel function, mathematical formula for (3); maximum number of iterations Number of ...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
