Chromia (cr2o3) Nanoparticles Synthesized by Using Cro3 via the Facile Solvothermal Process and Their Optical Properties

Chromia (Cr2O3) nanoparticles have been successfully synthesized via the facile solvothermal process, by using CrO3 in butanol and propanol as solvents. The functional groups of the samples were tested by the Fourier Transform Infrared (FTIR) spectroscopy. The as-synthesized nanoparticle sizes are calculated and confirmed to be 34 and 40 nm, by using X-ray Diffraction (XRD) and Transmission Ele...

Das informatische Weltbild von Studierenden

Trotz zahlreicher Gegenmaßnahmen hat die Informatik nach wie vor mit hohen Abbruchquoten und einem steigenden Desinteresse zu kämpfen. Wir vermuten, dass Wahlmotive sich in einem biographischen Lern-Prozess entwickeln, verändern und in Bezug auf informatische Weltbilder stabilisieren. Beim Analysieren individueller Computernutzungserfahrungen haben wir die Computernutzung unter dem Aspekt des i...

Einsatz von Agenten für das Selbstmanagement von Automatisierungssystemen

Automatisierte Zeitreihenanalyse von Fernerkundungsdaten für das Monitoring von Oberflächengewässern

Since 2012, the state of California faces an extreme drought, which impacts water supply in many ways. Advanced remote sensing is an important technology to better assess water resources, monitor drought conditions and water supplies, plan for drought response and mitigation, and measure drought impacts. In the present case study latest time series analysis capabilities are used to examine surf...
