Since November 2006, DLR operates F-SAR a new airborne SAR sensor beside its experimental airborne SAR sensor E-SAR. F-SAR is a totally new development utilizing most modern hardware. It is presently operated in X-band and has been supplemented recently being fully polarimetric. F-SAR already accomplished several flights and acquired SAR data in different operation modes, amongst others in alon...

This work aims to establish a relationship between volume and biomass with interferometric and radiometric SAR (Synthetic Aperture Radar) response from planted Eucalyptus saligna forest stands, using multi-variable regression techniques. X and P band SAR images from the airborne OrbiSAR-1 sensor, were acquired at the study area in the southeast region of Brazil. The interferometric height (Hint...

The species /time relationship (STR) describes how the species richness of a community increases with the time span over which the community is observed. This pattern has numerous implications for both theory and conservation in much the same way as the species /area relationship (SAR). However, the STR has received much less attention and to date only a handful of papers have been published on...

Texture analysis has been used extensively in the computer–assisted interpretation of SAR sea ice imagery. Provision of maps which distinguish relevant ice types is significant for monitoring global warming and ship navigation. Due to the abundance of SAR imagery available, there exists a need to develop an automated approach for SAR sea ice interpretation. Grey level co-occurrence probability ...

Various applications, like for instance algorithm design, mission planning, geo-referencing, change detection , Automatic Target Recognition (ATR) or SAR data analysis, rely on simulated synthetic aperture radar (SAR) images. However, there are different SAR simulation techniques with different advantages and disadvantages. Depending on the needs of a certain application, a suitable SAR simulat...

The article aims to analyze the progress of evolution cinnamic acid derivatives through a bibliographic review, describing main synthetic routes in obtaining this class, as well remarkable biological applications and application structure-activity relationship (SAR) strategy for design pharmacologically active molecules. methodology used consists reading analyzing articles, whose approach is de...

We introduce the Statistical Asynchronous Regression (SAR) method: a technique for determining a relationship between two time varying quantities without simultaneous measurements of both quantities. We require that there is a time invariant, monotonic function Y = u(X) relating the two quantities, Y and X. In order to determine u(X), we only need to know the statistical distributions of X and ...

The species-area relationship (SAR), i.e. the increase in species number with area, has been repeatedly used to predict species extinction, at both local and global scales, with habitat reduction. He and Hubbell (Nature, 2011; 473, 368e371), however, argued that the function that relates species loss with decreasing habitat area cannot be simply obtained reversing the species-area accumulation ...

Adipose triglyceride lipase (ATGL) catalyzes the degradation of cellular triacylglycerol stores and strongly determines the concentration of circulating fatty acids (FAs). High serum FA levels are causally linked to the development of insulin resistance and impaired glucose tolerance, which eventually progresses to overt type 2 diabetes. ATGL-specific inhibitors could be used to lower circulati...

12 Wide swath synthetic aperture radar (SAR), exemplified by the multibeam ScanSAR modes of Radarsat, can potentially deliver global near–real-time coastal wind fields with nearly 2 orders of magnitude greater spatial resolution ( 300 m) than conventional (active or passive) scatterometers ( 25 km). But this superior resolution comes with caveats. An understanding of the small-scale ocean scatt...
