Satellite Synthetic Aperture Radar (SAR) observations can provide a global view of ocean swell fields when using a specific ”wave mode” sampling. A methodology is presented to routinely derive integral properties of the longer wavelength (swell) portion of the wave spectrum from SAR Level 2 products, and both monitor and predict their evolution across ocean basins. SAR-derived estimates of swel...

The great potential of space-borne SAR images for semior fully-automatic mapping of topographic features has been shown by many approaches. While most of them focus on 2D mapping of topographic features, some preliminary research on the complex task of automatic delineation of 3D information in urban environments has been initiated in recent years. In this paper, we analyze the capabilities of ...

Introduction The aim of hydrography is basically to chart the underwater topography. A precise knowledge of the sea-bottom features has great relevance mainly in shallow waters, where navigational safety must be assured at any cost. Ideally, one should have available a complete series of maps of the sea-bottom topography. approximately 100 km x 100 km. Although the basic information provided by...

SAR plays a prominent role in TSCA screening of new chemicals and existing chemicals in commerce. SAR models for bioavailability, ecotoxicology and health toxicology endpoints are being used to identlify chemicals with the greatest potential for ecological or health hazard, to set testing priorities, and to provide scientific support for a testing recommendation. SAR models vary considerably in...

     It is widely known that the development of gullies causes the loss of a great amount of soil and can be considered as one of the principal causes of geo-environmental degradation. The study area of the present research is located in the eastern shores of Urmia Lake. This study sought to evaluate the rate of growth and effective factors on the area’s gully dynamic over a year. To achieve th...

Coastal zones are one of the world’s most densely populated areas and it is necessary to propose an accurate, cost effective, frequent, and synoptic method of monitoring these complex ecosystems. However, misclassification of sediments on exposed intertidal flats restricts the development of coastal zones surveillance. With the advent of SAR (Synthetic Aperture Radar) satellites, polarimetric S...

We describe in this article an annotation scheme for deep dependency syntax, built from the surface annotation scheme of the Sequoia corpus, abstracting away from it and expressing the grammatical relations between content words. When these grammatical relations take part into verbal diatheses, we consider the diatheses as resulting from redistributions from the canonical diathesis, which we re...

An algorithm for automatic identification of topic and focus of the sentence is presented, based on dependency syntax and using written input, which is much more ambiguous than spoken utterance. 1. The dichotomy of topic and focus, based, in the Praguean Functional Generative Description, on the scale of communicative dynamism (underlying word order), is relevant not only for a possible placeme...
