We discuss the implementation of an off-line air quality model (AQM). More precisely, how to design a code for an AQM that runs efficiently on a variety of computer platforms. We implemented our ideas in an AQM benchmark and we show the performance of this benchmark on the different architectural paradigms. A second subject of the paper is the I/O performance of the Cray T3E for an off-line mod...

Introduction and Purpose: Mashhad, one of the most populous cities in Iran, is facing air pollution due to motor vehicle emissions and industries. Therefore, this study aimed to evaluate the variations in Air Quality Index (AQI) during the spring of 2012-2014 and its spatial zoning with Arc GIS. Methods: In this descriptive study, the AQI values were calculated by the associ...

While technical characteristics, such as material used in the construction of display cases and their dimensions are important factors in terms of presentation quality as well as attracting the attention of the visitors, they can influence the inner air quality of the display case and preservation conditions of the exhibits too. This study intends to examine the effect of the technical characte...
