A quantitative assessment is presented of diffraction-limited stellar images with Strehl ratios of 0.250.30 obtained by selection of short-exposure CCD images of stars brighter than +6m at 810nm with the Nordic

AT&T participated in two tasks at TRECVID 2010: contentbased copy detection (CCD) and instance-based search (INS). The CCD system developed for TRECVID 2009 was enhanced for efficiency and scale and was augmented by audio features [1]. As a pilot task, participation in INS was meant to evaluate a number of algorithms traditionally used for search in a fully automated setting. In this paper, we ...

Nuisance algal blooms are widely reported from eutrophic and hypereutrophic systems, but are relatively rare in oligotrophic systems. Recently, the cyanobacterium Gloeotrichia echinulata has begun blooming in oligotrophic to mesotrophic lakes in the northeastern USA. We explored whether existing knowledge about G. echinulata, derived from eutrophic systems, would be useful in predicting the rec...

excellent decay length resolution of the CCD vertex detector. The B or B̄ production flavor is determined by exploiting the large forward-backward asymmetry of polarized Z → bb decays. This flavor tag is enhanced by incorporating additional information from the hemisphere opposite that of the reconstructed B decay. The B d − B̄ d mixing analysis uses the charge of high momentum kaons to identify ...

Zusammenfassung. Am Institut für Prozessrechentechnik, Automation und Robotik der Universität Karlsruhe (TH) wurde in den letzten beiden Jahren ein System zur Erzeugung projektorbasierter Erweiterter Realitäten entwickelt. Dieses besteht aus einem PC, zwei CCD-Kameras und einem handelsüblichen Videoprojektor, der sowohl zur Registrierung des Patienten (kodiertes Licht), als auch zur Projektion ...
