It has been well established that Synthetic Aperture Radar (SAR) images over the ocean can provide wind information over small spatial scales. SAR image data can be used quantitatively as an imaging scatterometer if the SAR is calibrated and a suitable wind retrieval model is available [Vachon & Dobson 1996; Wackerman et al. 1996; Fetterer et al. 1998]. Canada’s Radarsat SAR (C-band HH polarisa...

one of the main aims of water resource planners and managers is to estimate and predict the parameters of groundwater quality so that they can make managerial decisions. in this regard, there have many models developed, proposing better management in order to maintain water quality. most of these models require input parameters that are either hardly available or time-consuming and expensive to...

The new high-resolution synthetic aperture radar (SAR) satellite systems offer new possibilities for urban remote sensing. COSMOSkyMed and TerraSAR-X operate in X-band and both can deliver data with a spatial resolution of up to one meter. High-resolution SAR data is particularly useful for post-disaster damage assessment and monitoring, because SAR systems operate (almost) weather independent....

Epidemiologic studies suggest an association between lead exposure and caries. Our objective was to establish whether children with a higher lead exposure as toddlers had more caries at school age than children with a lower lead exposure. We used a retrospective cohort design. A sample of children who attended second and fifth grades in the Rochester, New York, public schools during the 1995-19...

In this paper, we describe an extension of an automatic road extraction procedure developed for single SAR images towards multiaspect SAR images. Extracted information from multi-aspect SAR images is not only redundant and complementary, in some cases even contradictory. Hence, multi-aspect SAR images require a careful selection within the fusion step. In this work, a fusion step based on proba...

Chemical carcinogenicity has been the target of numerous attempts to create predictive models alternative to the animal ones, ranging from short-term biological assays (e.g. mutagenicity tests) to theoretical models. Among the theoretical models, the application of the science of structure-activity relationships (SAR) has earned special prominence. The qualitative approach to SAR has lead to th...
