An important aspect of image and print quality is the existence of artifacts, such as compression or print artifacts. A general perceptual masking model, that describes the perceptual severity of artifacts on general background, could have been used to extract specific artifact detectors. However, currently general models are not mature enough to provide print artifact detectors for commercial ...

A four year long research programme divided into four phases has been designed for the first time to assess the combined Noise-Air quality and combined exposure to Noise-Air pollution at the curbside open-air microenvironment of Kolkata city, India. The results and the findings of the different phases of study had already been published. The objective of the review work is to fuse the findings ...

We welcome the Subcommittee’s review of “Air Pollution Modelling in Hong Kong”. Hong Kong’s air quality is a topic of great public concern. The lack of progress in improving air quality has led many to question the effectiveness of our air quality management system. Most people understand that air quality modelling is important for our air quality management system because of its role in air qu...

Recent epidemiological evidence strongly suggests that ambient-particle-associated acidity is more closely correlated with total mortality and hospital admissions for respiratory disease than indices of total particulate mass. In addition, evidence is accumulating to support the hypothesis that the number of ultrafine (d < or = 200 nm) acid particles, rather than ambient mass, is an important d...
