observing urban soilpollution usingmagnetic susceptibility

چکیده
pollution of urban soils dramatically reduces life and environmental quality. the most commonpollutants are heavymetals and organic contaminants like polycyclic aromatic hydrocarbons and polychlorinatedbiphenyl. main source of these pollutants is fossil fuels which are pervasive in urban and/or industrializedareas. identifying type and intensity of the pollution is essential to prepare an effective hazard mitigationplan. the study has been focused on the determining the distribution of pollutants in denizli city center. themagnetic susceptibility measurements and chemical analysis are performed at several locations. the lowfrequency magnetic values are differing significantly over the study area. they are concentrated at the northernand southeastern parts of the study area. the spatial distribution of the pli proved that the industrial areashowed very high anomalous. they mainly come from magnetic particle sources in the area. scattering patternsof fe, pb, cu, cr andni are compatiblewith the susceptibilitymaps and the topography.the highest concentrationof ni, cr, pb and cu oxides elements are observed near the major roads and close to the industrial enterprises inthe northern part of the city. high correlations are documented between low frequency magnetic susceptibilityand fe, si, pb and cr. the method can effectively be employed for monitoring the urban soil pollution.

متن کاملObserving Dynamic Urban Environment through Stereo-Vision Based Dynamic Occupancy Grid Mapping
Occupancy grid maps are popular tools of representing surrounding environments for mobile robots/ intelligent vehicles. When moving in dynamic real world, traditional occupancy grid mapping is required not only to be able to detect occupied areas, but also to be able to understand the dynamic circumstance. The paper addresses this issue by presenting a stereo-vision based framework to create dy...

متن کاملObserving Processes
This paper discusses the sorts of observations of processes that are appropriate to capture priority. The standard denotational semantics for CSP are based around observations of traces and refusals. Choosing to record a little more detail allows extensions of CSP which describe some very general processes including those that include priority. A minimal set of observations yields a language an...
