REAL-TIME FORECASTING METHOD OF URBAN AIR QUALITY BASED ON OBSERVATION SITES AND THIESSEN POLYGONS

This paper proposes a real-time urban air quality forecasting method based on monitoring sites and Thiessen polygon. Firstly, the concentration of pollutants affecting air quality is obtained through the real-time observations of the monitoring sites deployed in wireless sensor network, according to which the air quality index (AQI) can be calculated and air quality levels and categories can be graded. Then, Thiessen polygons are constructed based on the monitoring sites and the air quality

Analysis and Forecast of Urban Air Quality Based on BP Neural Network

I. INTRODUCTION Air quality prediction, as the name suggests, is based on the historical emission concentration values of various pollutant items in the air to predict the concentration values of various pollutants in the air pollution in the future and the air environment quality[1]. As China’s rapid economic development has led to serious atmospheric environmental pollution problems, the state and the public have paid more and more attention to the treatment and prevention of air pollution

AN AIR QUALITY MONITORING SYSTEM FOR URBAN AREAS BASED ON THE TECHNOLOGY OF WIRELESS SENSOR NETWORKS

Air pollution is one of environmental issues that cannot be ignored. The heavy transportation and urbanization result in the air pollutants concentrated in certain areas. Inhaling pollutants for a long time causes damages in human health. Traditional air quality monitoring methods, such as building air quality monitoring stations, are typically expensive. In addition, monitoring stations are generally less densely deployed and provide low resolution sensing data. This paper proposes an urban

CURRENT VENTILATION AND AIR QUALITY PROBLEMS AGAINST HISTORICAL SOLUTIONS

The paper describes the issue of ventilation and air quality in buildings with reference to regular tightening of heating standards. The purpose of the work is to show the risks related to excessive insulation of buildings, which is thought to have a negative influence on users’ well-being and health. The development of issues related to thermal comfort has often led to erroneous solutions. As a result, problems such as “Sick Building Syndrome” and “Building Related Illness” has developed in

THERMAL IMPROVEMENT IN RESIDENTIAL BUILDINGS IN VIEW OF THE INDOOR AIR QUALITY – CASE STUDY FOR POLISH DWELLING

outdoor parts (both walls and a roof), Window replacement, Central heating improvement. Window replacement, being one of the major aspects in thermal refurbishment, frequently results in the deterioration of indoor environment conditions. Modern windows with a low heat transfer coefficient are airtight and lead to insufficient air exchange in buildings [5] as well as the rise in relative humidity and CO2 concentration. The air quality in rooms depends on the air parameters, including air temperature

COOLING DEMAND IN MUSEUM PREMISES – NUMERICAL PREDICTION AND MEASUREMENT VALIDATION

The paper presents the results of identification and assessment of the energy demand for cooling purposes in the museum building. The analysis of cooling demand and assessment of indoor air quality were performed by the simulation analysis and validated by the measurement campaign of the indoor air quality in the building under consideration. For the purpose of thermal analysis the IDA ICE software was used. All simulations were carried out using meteorological data recorded by the local

A CASE STUDY ON PERCEPTIONS OF PUBLIC TRANSPORTATION IN THE EASTERN PROVINCE OF SAUDI ARABIA

The Eastern Province of the Kingdom of Saudi Arabia (KSA) is home to almost 5,000,000 people and is a major contributor to Saudi Arabia’s economic strength. The area has experienced population growth of about 3.5% per year and rapid urbanization over the past few decades. With this increase in population has come a significant escalation in automobile traffic, which, in turn, has contributed to poor air quality in the province. Two of the major cities in the area were listed on the World

The Monitoring and Wireless Transmission System of PM2.5 in the Scenic

This Scenic area has large traffic volume and complex environment and some scenic areas need to be protected. So developing an air quality monitoring system is very important. In this paper, the temperature sensor, the PM2.5 sensor and the wireless transmission module were combined by the MCU. It monitors the spot in PM2.5 concentration and the temperature information. When the PM2.5 concentration is higher than the threshold, the wireless transmission module sends the warning signal. So the

This second investigation enabled to estimate the yearly average NOx emissions by all construction works in Germany for 13500 Mg, therein 6300 Mg from earthworks, and 170 Mg from asphalt paving. While emissions connected with construction works are quite good recognized, the influence of construction works on local air quality are not so
