Leightweight Urban Computation Interchange (LUCI) System
In this paper we introduce LUCI, a Leightweight Urban Calculation Interchange system, designed to bring the advantages of calculation and content co-ordination system to small planning and design groups by the means of an open source middle-ware.The middle-ware focuses on problems typical to urban planning and therefore features a geo-data repository as well as a job runtime administration, to coordinate simulation models and its multiple views.The described system architecture is accompanied by two exemplary use cases, that have been used to test and further develop our concepts and implementations

The James Webb Space Telescope Mission
Twenty-six years ago a small committee report, building on earlier studies,
expounded a compelling and poetic vision for the future of astronomy, calling
for an infrared-optimized space telescope with an aperture of at least .
With the support of their governments in the US, Europe, and Canada, 20,000
people realized that vision as the James Webb Space Telescope. A
generation of astronomers will celebrate their accomplishments for the life of
the mission, potentially as long as 20 years, and beyond. This report and the
scientific discoveries that follow are extended thank-you notes to the 20,000
team members. The telescope is working perfectly, with much better image
quality than expected. In this and accompanying papers, we give a brief
history, describe the observatory, outline its objectives and current observing
program, and discuss the inventions and people who made it possible. We cite
detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space

Digitalisierte historische Bauzeitschriften auf dem Digitalen Repositorium (OPUS)
Die UniversitĂ€tsbibliothek der BTU Cottbus-Senftenberg digitalisiert seit 2005 historische Bauzeitschriften, um hĂ€ufig nachgefragte Titel digital verfĂŒgbar zu machen. Diese MaĂnahme dient nebenbei auch dem Bestandsschutz.
Um Ăberschneidungen zu vermeiden, wird zunĂ€chst ĂŒberprĂŒft, ob bereits durch andere Einrichtungen wie z.B. der Zentral- und Landesbibliothek Berlin, beziehungsweise Projekte (z.B. ANNO, ZDB) digitalisiert wird.
Der Workflow des Digitalisierungsprojekts verlĂ€uft folgendermaĂen: Nach dem Scannen werden die Dokumente mittels OCR (Optical Character Recognition) in maschinenlesbare PDF-Dateien umgewandelt. AnschlieĂend erfolgt der Upload in Opus und die Vergabe der Metadaten fĂŒr die inhaltliche und formale Beschreibung. Diese dienen der Suchâ und Auffindbarkeit der Bauzeitschriften auch auĂerhalb von OPUS.
Die Digitalisate werden auf dem Digitalen Repositorium der BTU Cottbus-Senftenberg archiviert und sind frei zugÀnglich. Die digitalisierten Zeitschriften werden in der Zeitschriftendatenbank und der Elektronischen Zeitschriftenbibliothek nachgewiesen.
Bei der Digitalisierung wurde darauf geachtet, dass die BestÀnde möglichst vollstÀndig abgebildet sind und es wurde ein Zeitschnitt bei 1920 gemacht.
Dieser Service wird von den Mitarbeitern der BTU, anderen Einrichtungen und externen Nutzern sehr gut angenommen
Revealing the local crystallinity of single silicon core-shell nanowires using tip-enhanced Raman spectroscopy
Tip-enhanced Raman spectroscopy is combined with polarization angle-resolved spectroscopy to investigate the nanometer-scale structural properties of coreâshell silicon nanowires (crystalline Si core and amorphous Si shell), which were synthesized by platinum-catalyzed vaporâliquidâsolid growth and silicon overcoating by thermal chemical vapor deposition. Local changes in the fraction of crystallinity in these silicon nanowires are characterized at an optical resolution of about 300 nm. Furthermore, we are able to resolve the variations in the intensity ratios of the Raman peaks of crystalline Si and amorphous Si by applying tip-enhanced Raman spectroscopy, at sample positions being 8 nm apart. The local crystallinity revealed using confocal Raman spectroscopy and tip-enhanced Raman spectroscopy agrees well with the high-resolution transmission electron microscopy images. Additionally, the polarizations of Raman scattering and the photoluminescence signal from the tipâsample nanogap are explored by combining polarization angle-resolved emission spectroscopy with tip-enhanced optical spectroscopy. Our work demonstrates the significant potential of resolving local structural properties of Si nanomaterials at the sub-10 nanometer scale using tip-enhanced Raman techniques
