Detection of Rossby waves in multi-parameters in multi-mission satellite observations and HYCOM simulations in the Indian Ocean
No full textRossby waves are difficult to detect with in situ methods. However, as we show in this paper, they can be clearly identified in multi-parameters in multi-mission satellite observations of sea surface height (SSH), sea surface temperature (SST) and ocean color observations of chlorophyll-a (chl-a), as well as 1/12° global HYbrid Coordinate Ocean Model (HYCOM) simulations of SSH, SST and sea surface salinity (SSS) in the Indian Ocean. While the surface structure of Rossby waves can be elucidated from comparisons of the signal in different sea surface parameters, models are needed to gain direct information about how these waves affect the ocean at depth. The first three baroclinic modes of the Rossby waves are inferred from the Fast Fourier Transform (FFT), and two-dimensional Radon Transform (2D RT). At many latitudes the first and second baroclinic mode Rossby wave phase speeds from satellite observations and model parameters are identified. Wavelet transforms of these multi-parameters from satellite observations and model simulations help to discriminate between the annual and semi-annual signal of these Rossby waves. This comprehensive study reveals that the surface signature of Rossby waves in SSS anomalies is likely to be between 0.05 and 0.3 psu in the South Indian Ocean.<br/
Elektronischer Zahlungsverkehr. Probleme und Chancen sozialverträglicher Technikgestaltung bei der Automatisierung
No full textDie fortschreitende Automatisierung des Geldverkehrs wird zu Veränderungen der Vertriebs- und Betriebsorganisation sowie der Arbeitsplätze in Kreditinstituten führen, aber auch in der gewerblichen Wirtschaft und in Behörden sichtbar werden. Darüber hinaus werden neue Anforderungen an das Verhalten der Kunden und Konsumenten gestellt, insbesondere im Bereich der Selbstbedienung. Um Erkenntnisse über Verlauf und Richtung der Automatisierungsprozesse zu gewinnen und um die Voraussetzungen für eine Gestaltung dieser Prozesse verbessern zu können, wurden die technischen Entwicklungslinien sowie sozialen und ökonomischen Auswirkungen auf die Organisation, auf Arbeitsplätze und private Haushalte sowie die Möglichkeiten zur sozialverträglichen Technikgestaltung durch die Kreditinstitute als Anwender und für die betroffenen Beschäftigten erarbeitet

Synthesis and characterization of a semiflexible liquid crystalline polymer with a broad nematic region
No full textIn this paper, we report on the synthesis and detailed characterization of a new semiflexible nematic liquid crystalline polyester which could serve as a ‘model’ polyester for a variety of physical and physico-chemical investigations. The polymer is a nematic liquid over a wide temperature range-from the glass transition temperature at 95°C to the isotropic transition at 240°C. We expect this polyester to be particularly useful for studying the effect of flow on the orientation of liquid crystalline polymers, as well as the production and removal of disclinations
