The report of diseases related to and numbers of patients suffered from air pollution increase rapidly over time. Hence, the requirement of measuring the air quality index (AQI) precisely and...
The U.S. Environmental Protection Agency (EPA) created a tool called the Air Quality Index (AQI) to inform the public of the level of air pollution and the risks it can pose to our health. Air quality can change very quickly, and the AQI allows people to stay on top of current air ...
空气质量指数 (Air Quality Index): AQI是政府机构以及公共卫生组织使用的指数,通过研究和图表的形式来展现空气中的污染指数,同时也用于预测接下来几个月甚至几年的趋势。 气密性 (Airtightness): 气密性定义为控制或消除建筑体中空气的双向泄漏,气体泄漏通常发生在建筑外壳有裂痕和泄漏点的区域。(由风力和堆叠压力/...
the autoregressive integrated moving average (ARIMA) model, the gray model, and the multiple linear regression (MLR) model4,5proposed an algorithm to assess the pollution level of air quality parameters and create a new air quality index based on the fuzzy reasoning system ...
