The surface of the biomass monitoring is blocked rotational grazing land prerequisite for high scores (GF - 1) satellite multispectral image and artificial index test, using ENVI software GF1 or GF6 data (radiation calibration atmospheric correction RPC orthographical correction), then calculate vegetation (NDVI), NDVI can detect growth status, coverage eliminate part radiation error manual col...

Abstract. Cities are particularly affected by climate change impacts. Due to global warming, the frequency and intensity of summer heat events increases for many cities around globe. Urban climatological studies have shown significant positive trends in number hot days tropical nights. Heat stress is an important health as well economic risk. Thus, urban planning needs adapt change. This requir...

the coastal region of chabahar gulf with 1113.7km2 area has been located in the southeast of iran. in this research, satellite images of etm+ (2004) were used in order to zoning of sedimentary environments in this gulf. methodology of this research was baesd on synthesis of supervised and unsupervised classifications in gis and envi softwares. based on studies and calculation of oif index, the ...

This article studies, from an ecosocial and intercultural point of view, the novels writer Nathacha Appanah located in tropical ecosystems, particularly vulnerable to unforeseeable meteorological events, seismic events others. The emphasis is put on envi-ronmental characteristics scenographies their consequences for plot’s characters. examines strategies used by author develop social environmen...

polychlorinated dibenzo-p-dioxins (PCDD), whereas 135 congeners belong to the group of polychlorinated dibenzofurans (PCDF). Figure 1 shows general structures of PCCD and PCDF. Dioxins are widespread contaminants with no specific usage and they are not produced. They mostly appear as unwanted byproducts of different industrial processes, combustion in waste incineration, and in the production o...

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on-board the NASA's Terra spacecraft provides along-track digital stereo image data at 15m resolution with a base-height ratio 0.6. Automated stereocorrelation procedure was implemented using the ENVI 4.1 software to derive DEMs with 15m×15m in 43 km long and 50 km wide area using the ASTER stereo images. The cloud areas...

This thesis investigates several issues in data and computation modeling for scientific problem solving envi-ronments (PSEs). A PSE is viewed as a software system that provides (i) a library of simulation components,(ii) experiment management, (ii) reasoning about simulations and data, and (iv) problem solving abstrac-tions. Three specific ideas, in functionalities (ii)-(iv), form t...
