Discrete peaks in above threshold double ionization spectra authored by Manfred Lein, E. K. U. Gross, Volker Engel Abstract Above threshold double ionization ATDI peaks were observed in a variety of laser parameters. The peaks appear not only in the photoelectron total energy spectra, but also in the recoil ion momentum distributions. A numerical method to approximately extract the former from the latter was proposed.

Plate height model of ion mobility mass spectrometry Part 2 Peak to peak resolution and peak capacity verfasst von M rk Grabarics, Maike Lettow, Ansgar T. Kirk, Gert von Helden, Tim J. Causon, Kevin Pagel Abstract In a previous work, we explored zone broadening and the achievable plate numbers in linear drift tube ion mobility mass spectrometry through developing a plate height model 1 . On the basis of these finding...

Estimation of the instantaneous peak flow from maximum daily flow A comparison of three methods verfasst von J. Ding, U. Haberlandt, J. Dietrich Abstract Three different methods are compared to estimate the instantaneous peak flow IPF from the corresponding maximum daily flow MDF , as the daily data are more often available at gauges of interest and often with longer recording periods.

Dual Active Bridge Converter Simple Peak Current Limitation by Dual Phase Shift Control authored by Lukas Fräger, Niklas Badenhop, Sascha Langfermann, Michael Owzareck, Dennis Kampen, Jens Friebe Abstract Dual Active Bridge DAB converters offer highly efficient conversion of DC Currents and voltages especially in the range of the transformer turns ratio. At voltage ratios different from the transformer ratio, the peak current...

Viscosity, Boson Peak and Elastic Moduli in the Na 2 O SiO 2 System authored by Michele Cassetta, Gino Mariotto, Nicola Daldosso, Emanuele De Bona, Mattia Biesuz, Gian Domenico Sorarù, Renat Almeev, Marco Zanatta, Francesco Vetere Abstract The temperature and chemical dependence of the melt viscosity are ubiquitous in the model development of the volcanic dynamics, as well as in the glass production and design. We focussed on the yet ...

Temperature dependent broadening of coherent current peaks in InAs double quantum dots authored by Olfa Dani, Robert Hussein, Johannes C. Bayer, Sigmund Kohler, Rolf J. Haug Abstract Quantum systems as used for quantum computation or quantum sensing are nowadays often realized in solid state devices as e.g. complex Josephson circuits or coupled quantum dot systems.

Flood frequency analysis using mean daily flows vs. instantaneous peak flows verfasst von Anne Bartens, Bora Shehu, Uwe Haberlandt Abstract In many cases, flood frequency analysis FFA needs to be carried out on mean daily flows MDF instead of instantaneous peak flows IPF , which can lead to underestimation of design flows.
