Air pollution, which is mainly caused by industrialization, intensive transportation, and the
heating of buildings, is one of the most important problems in large cities because it …

Emissions from power plants constitute a major part of air pollution and should be
adequately estimated. In this paper, we consider the problem of estimating nitrogen dioxide …

Traditional adaptive Kalman filtering algorithms based on innovation are often used to solve
the problem of reduced or even divergent filtering estimation accuracy under abnormal …

Prediction algorithms enable computers to learn from historical data in order to make
accurate decisions about an uncertain future to maximize expected benefit or avoid potential …

Using low-cost gas sensors for air quality monitoring promises cost effective and convenient
measurement systems. Nevertheless, the results obtained have a questionable quality due …

Significant portions of European cities' population are still exposed to levels of air pollution
deemed harmful by the World Health Organization. Given the high impact of air pollution …

The current compliance networks of automatic air-quality monitoring stations in large urban
environments are not sufficient to provide spatial and temporal measurement resolution for …

In recent years, low-cost air sensors designed to measure ambient particulate matters and
trace gases have been changing the world of air quality monitoring. Although low-cost …

In this paper, we present the results of the evaluation of three low-cost laser sensors and
comparison with the standard device Metone Aerocet 531s which is capable of counting …

Modern cities are densely populated spaces and number of people living in cities is
increasing rapidly by years. The air monitoring stations exist in most of the cities to monitor …
