Evaluation of Seasonal and Spatial Variations of Air Quality Index and Ambient Air Pollutants in Isfahan Using Geographic Information System
Introduction: Due to more than 1.7 million population, many vehicles and large industries around Isfahan, it has become one of the most polluted cities in Iran. The aim of this study was a spatial analysis of the concentrations of air pollutants and the air quality index (AQI). Materials and Methods: In this descriptive and evaluative study, the air quality data of 7 monitoring stations in 201...
متن کاملRefractive index sensing with an air-slot photonic crystal nanocavity.
We investigate an air-slot photonic crystal cavity for high-precision refractive index sensing. The high quality factor approximately 2.6x10(4) of the cavity, along with a strong overlap between the resonant mode and the hollow core region, allows us to achieve an experimental sensitivity of 510nm per refractive index unit (RUI) and a detection limit below 1x10(-5)RUI. The device has a remarkab...
متن کاملGroup Tracking in an Air Surveillance System
An operational Air Surveillance System shall generate a stable and reliable air picture. In dense target situations the quality of available sensor data is reduced. System models which take into account correlated flight paths of aircraft formations help to compensate the lack of information in dense situations. The paper presents algorithms to detect groups, to evaluate the relative behavior o...
متن کاملDesigning and Implementing an Asthma Management System Based on Air Pollution Data
Introduction: Asthma is an untreatable but manageable disease that has increased dramatically during the last fifty years due to contamination of the surrounding environment with triggers such as air pollution and has become one of the common chronic diseases throughout the world. Researchers consider allergies and environmental stimuli to be one of the essential components of asthma management...
متن کاملDesign and operation optimization of an air conditioning system through simulation: an hour-by-hour simulation study
In the present research, performance validation of a Heating, Ventilation, and Air Conditioning (HVAC) system operating in a library building was conducted. The operating HVAC system was studied in terms of the provided indoor air conditions and energy consumption level. The fieldwork measurements showed that the HVAC system is not capable of providing the desired indoor air conditions based on...
