Monitoring and controlling air quality parameters form an important subject of atmospheric and environmental research today due to the health impacts caused by the different pollutants present in the urban areas. The support vector machine (SVM), as a supervised learning analysis method, is considered an effective statistical tool for the prediction and analysis of air quality. The work present...

The Software quality management system has been developed. allows you to determine the state of software at each hierarchical level system, taking into account cost ensuring required quality. also IT company manager set potential costs for transition indicators from one another. It was found out that is a multifaceted concept can be adequately expressed by some structure characteristics and att...

This paper addresses the transformation of traditional software quality control techniques to a proactive quality assurance program within embedded systems and other mission critical software: Software plays an increasingly important role in every product and organization. The number of mission critical applications, those with a high cost of failure (air traffic control systems and other life ...

Background: Today, air pollution is one of the major problems in large cities including Isfahan. Methods: The objective of this study was to investigate the variations of ozone (O3), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), sulphur dioxide (SO2), and particulate matter (PM10) concentrations in different months at three stations and also to explore ...

cement powder size classification efficiency significantly affects quality of final product and extent of energy consumption in clinker grinding circuits. static and dynamic or high efficiency air separators are being used widely in closed circuit with multi-compartment tube ball mills, high pressure grinding rolls (hpgr) and more recently vertical roller mills (vrm) units in cement plants to c...

the wide availability of data on air pollutant emissions, the knowledge already achieved on theset of chemical and photochemical reactions in the troposphere, the ability to access real time weatherconditions at the local scale that determine the transport and transformation of gases and aerosol, now make it possible to obtain credible and reliable predictions, retrospective analyses and/or fut...
