TL;DR: In this article, a seismic hazard reassessment of the site of an existing nuclear power plant in Slovenia was performed based on existing data only, and a multiple model approach was applied to overcome the lack of data and to handle uncertainties in the data.

TL;DR: In this article, three seismic source models were used to delineate seismic sources in the map of seismic energy release and a map of earthquake epicenter density, and the geometry of the third model was taken from the probabilistic seismic hazard analysis of a nuclear power plant in Slovenia.
Abstract: The preparation of the preliminary seismic hazard maps of the territory of Slovenia has been based on an expansion of the basic approach laid out by Cornell in 1968. Three seismic source models were prepared. Two of them are based mainly on the earthquake catalogue using the Poissonian probability model. A map of seismic energy release and a map of earthquake epicenter density are used to delineate seismic sources in these models. The geometry of the third model which is based on a rough estimate of seismotectonic setting is taken from the probabilistic seismic hazard analysis of a nuclear power plant in Slovenia. Published ground motion attenuation models based on strong motion records of recent strong earthquakes in Italy are used. Test maps for variable and uniform b-values are presented. The computer program, Seisrisk III, developed by the U.S. Geological Survey is used.

14 Oct 2010TL;DR: By analyzing the differential interferometric results generated with different baseline estimation methods, it can be concluded that the new method used by this article is correct and feasible.
Abstract: Interferometric baseline plays a very important role in InSAR data processing, and it will directly affect the accuracy of interferometric result. In this article, three classical baseline estimation methods were described. By comparing and combining three methods, a new baseline estimation method and its flow were listed. RADARSAT-2 satellite image data and grid digital elevation model ASTER GDEM (30m resolution) in Kailuan area are used as sample data. By analyzing the differential interferometric results generated with different baseline estimation methods, it can be concluded that the new method used by this article is correct and feasible.

21 Nov 2008TL;DR: In this paper, the average single scattering albedo was calculated from reflectance spectra on the basis of Hapke radiative transfer model, and the error of mineral abundances derived from reflective spectra was 20.05% and 5.03% respectively, which shows that mixture spectra of all kinds of mineral belongs to nonlinear mixing.
Abstract: Quantitatively retrieving mineral abundances from hyperspectral data is one of promising and challenging geological
application fields of hyperspectral data, and the most basic obstacles are mixture characteristic of mineral spectra and
deconvolution method of mixture spectra. A series of mineral mixture schemes were designed, and several kinds of
mineral were used for investigating the two obstacles. In the experiment, average single scattering albedo was calculated
from reflectance spectra on the basis of Hapke radiative transfer model. The error of mineral abundances derived from
reflectance spectra and single scattering albedo is 20.05% and 5.03% respectively, which shows that mixture spectra of
all kinds of mineral belongs to nonlinear mixing, and Hapke model is a good method of resolving this problem. Finally,
deconvolution of continuum-removed single scattering albedo spectra other than single scattering albedo spectra is
considered to be the possible method that could be applied to imaging spectrometer data (e.g. AVIRIS and Hyperion data)
to retrieve mineral abundances successfully, because intensity of spectra is influenced by terrain considerably rather than
shape of spectra feature is influenced by terrain slightly.
