Air quality

This study used the straight-type air blade, which is more common than the elbow-type, to evaluate the effect of blade angle on air uniformity in small industrial drying equipment. CFD method is used to predict the air distribution in the chamber, which has a strong influence on the drying rate efficiency and the product quality.

The Air Quality Index (AQI) is a tool used to measure the impact of air pollution on health over time. We present a new way for using GP to evolve models for AQI forecasting in this work GP can evolve more accurate AQI forecasting models than other standard machine learning algorithms, according to experimental results using datasets obtained from various stations across multiple cities in India.

Air pollution is one of the leading risk factors for death but also a significant contributor to the global disease burden, affecting quality of life. According to a World Health Organisation (WHO) report, seven million people die from air pollution every year, and 9 out of 10 people worldwide breathe polluted air. Any person can be affected by exposure to polluted air, especially the elderly, children, pregnant women, and people with comorbidities.

Ebook "Solid state gas sensors – Industrial application" focuses on what the research community labels as solid state gas sensors, where a gas directly changes electrical properties of a solid, which serves as a primary signal for the transducer. Therefore electrochemical, mass/viscoelastic, optical and calorimetric effects are out of the scope of this topic and have not been included.

Asphalt concrete pavement often appears damaged such as rutting, fatigue crack, potholes, etc. at high air temperature, heavy rain in long time, or at locations with high traffic, large horizontal force, and poor-quality construction sites. This causes a deterioration in the service quality, leading to a lot of maintenance costs.
