the present research analyzes air quality in ahvaz, a city in the south of iran, paying special attention to sulfur dioxide (so2). in order to prepare the average data in the city, measurements have been carried out between 2009 and 2010 in two different locations. relations between sulfur dioxide and some meteorological parameters have been calculated statistically, using the daily average dat...

The problem faced in this paper concerns the recognition of simple and complex geometric primitives point clouds resulting from scans mechanical CAD objects. A large number points, presence noise, outliers, missing or redundant parts uneven distribution are main problems to be addressed meet need. In article we propose a solution, based on Hough transform, that can recognize is robust parts. Ad...

A four year long research programme divided into four phases has been designed for the first time to assess the combined Noise-Air quality and combined exposure to Noise-Air pollution at the curbside open-air microenvironment of Kolkata city, India. The results and the findings of the different phases of study had already been published. The objective of the review work is to fuse the findings ...

in the present study, air quality analyses for ozone (o3) were conducted in ahvaz, a city in the south of iran. the measurements were taken from 2009 through 2010 in two different locations to prepare average data in the city. relations between the air pollutant and some meteorological parameters were calculated statistically using the daily average data. the wind data (velocity, direction), re...

In order to explore the temporal and spatial variability of non-point source pollution in an agriculture watershed, water quality quantity characteristics five flood events at Shuangqiao station Siheshui watershed (south China) were monitored. Five pollutants, including BOD5, TSS, TP, TN, NH3-N, measured analyzed. The pollutant concentrations load-transport rates investigated. It is shown that ...
