air conditioning is widely applied for the improvement of standard of living in human life. this present investigation focused on the prediction of indoor air quality characteristics of air conditioned car using fuzzy logic algorithm. the conditioned space was selected and the experiments were planned as per design of experiments to study the effect of human load, fresh air supply and air veloc...

A s government agencies and businesses become more dependent on commercial offthe-shelf (COTS) software products to automate tasks, the ability to determine product quality and suitability has become increasingly important. Unfortunately, the lack of a standard, well-defined software product evaluation approach has resulted in many organizations making large investments in poor product choices....

Introduction: The rapid urbanization coupled with industrial development in Indian cities has led to air pollution that causes adverse effects on the health of human beings. So, it is crucial to track the quality of air in industrial areas of a city to insulate the public from harmful air pollutants.  The present study examined and predicted air quality index levels in industrial areas located ...

Introduction: This study aimed to evaluate the most important public environmental issues and concerns, the public knowledge about these issues, as well as the quality of environmental issues in Rafsanjan, Iran. Materials and Methods: In this descriptive-analytical study, 384 people were randomly selected from Rafsanjan City and their public environmental issues and concerns were evaluated. Th...

indoor air quality is a general concept that specifies to air quality of buildings and is related to health and relaxation in there. this index contains removal of all contaminants for example microbial, gas types, particles, etc., and suggests remedial approaches toward refreshing the building air and air circulation in these constructions. in this article we study indoor air quality index (ia...

Air Quality Forecasting (AQF) is a new computational discipline that attempts to predict atmospheric pollution, especially high levels of ozone. The application is complex, incorporating weather models, emissions processing and chemical transport models at multiple levels of refinement; it poses substantial computational and storage requirements. Deployment in a grid is one way in which timely ...

The characteristics of the combustion temperature, flow velocity, CO distribution and NOx emissions of a 10 MW gas burner at different primary to secondary air ratios are numerically studied using computational fluid dynamics software Fluent. The results indicate that the primary to secondary air ratio in gas burner determines the combustion quality through influencing some parameters directly,...
