No visible optical variability from a relativistic blast wave encountering a wind-termination shock

Gamma-ray burst afterglow flares and rebrightenings of the optical and X-ray light curve have been attributed to both late time inner engine activity and density changes in the medium surrounding the burster. To test the latter, we study the encounter between the relativistic blast wave from a gamma-ray burster and a stellar wind termination shock. The blast wave is simulated using a high perfo...

Reconstructing Visible Regions from Visible Segments

An algorithm is presented for reconstructing visible regions from visible edge segments in object space. This has applications in hidden surface algorithms operating on polyhedral scenes and in cartography. A special case of reconstruction can be formulated as a graph problem: "Determine the faces of a straight-edge planar graph given in terms of its edges." This is accomplished in O(n log n) t...

Endovascular coil visible in a visible vessel.

was being admitted for chemotherapy for stage IV ovarian cancer. After large−vol− ume resuscitation, upper gastrointestinal endoscopy was performed because of hematemesis. A large ulcer (2 ” 2 cm) in the posterior wall of the duodenal bulb with a large, actively bleeding visible ves− sel (estimated diameter 5 ± 6 mm) was seen. Despite repeated local epinephrine injections, heater probe coagulat...

Developments for a High-resolution Wind Product from the Hrv Visible Channel of the Meteosat Second Generation

The Satellite Application Facility -SAFfor Eumetsat in support to nowcasting (and very short-range forecasting) develops algorithms and software to provide cloud, precipitation, air mass and synoptic analysis products, from data of the future MSG satellite system. A wind product -HRWwas also included to add some dynamical information. It is centred in the exploitation of the HRV channel at 1km ...

The general methodology to derive the sea surface wind field from SAR is to apply an empirical Geophysical Model Function (GMF) to the calibrated SAR image using wind direction from external sources or wind streaks visible in SAR

 Abstract— A Geophysical Model Function (GMF), denoted XMOD2, is developed to retrieve sea surface wind field from Xband TerraSAR-X/TanDEM-X (TS-X/TD-X) data. In contrast to the previously developed XMOD1, XMOD2 consists of a nonlinear GMF, and thus, it depicts the difference between upwind and downwind of the sea surface backscatter in X-band SAR imagery. By exploiting 371 collocations with i...
