Dynamics of gas phase Ne* + NH3 and Ne* + ND3 Penning ionisation at low temperatures

Andreas Osterwalder, Justinas Jankunas, Benjamin Bertsche

Two isotopic chemical reactions, Ne* + NH_3, and Ne* + ND_3, have been studied at low collision energies by means of a merged beams technique. Partial cross sections have been recorded for the two reactive channels, namely, Ne* + NH_3 → Ne + NH^+_3 + e −, ...

Approximate solution of the probability density function of bedload transport rate over multiple time scales.

Christophe Ancey, Joris Heyman, François Mettra, Hongbo Ma

Bedload transport rate in mountain rivers is highly fluctuating and has strong stochastic behavior even under steady flow conditions. Its stochastic description thus offers deeper insights into its dynamics than the deterministic one. As a random quantity, ...

Time scale analysis of bedload discharge over steep slopes: from intermittency to white noise.

Christophe Ancey, Joris Heyman, François Mettra, Hongbo Ma

Bedload transport remains largely unpredictable in steep slope rivers. Comparing experimental data obtained in a steep slope flume and a stochastic model, we show that bedload discharge statistics strongly depend on the measurement time and spatial scale. ...

Can satellite based pattern-oriented memory improve the interpolation of sparse historical rainfall records?

Anton Schleiss, Théodora Cohen Liechti

Ther is a standing challeng in obtaining long localized records of rainfall data in many large river basins of the developing world. Recent spaceborne instrumentation offers a constente source of rainfall information, but this information covers only a rel ...

Dynamics of Stochastically Blinking Systems. Part I: Finite Time Properties

Martin Hasler, Igor Belykh

We consider dynamical systems whose parameters are switched within a discrete set of values at equal time intervals. Similar to the blinking of the eye, switching is fast and occurs stochastically and independently for different time intervals. There are t ...

Seasonal simulation of drifting snow sublimation in Alpine terrain

Michael Lehning

We estimate seasonal drifting snow sublimation at a study site in the Swiss Alps with the numerical model Alpine3D using external wind fields from the Advanced Regional Prediction System on a high-resolution grid (10 m). Novel in the field of snow transpor ...

Patterns of interval correlations in neural oscillators with adaptation

Tilo Schwalger

Neural firing is often subject to negative feedback by adaptation currents. These currents can induce strong correlations among the time intervals between spikes. Here we study analytically the interval correlations of a broad class of noisy neural oscilla ...

Modelling hybrid demand (e-commerce " plus " traditional) evolution: A scenario planning approach

Rémy Glardon, Naoufel Cheikhrouhou, Luca Canetta

This work presents a "3 steps-2 aggregation levels" methodological approach for modelling the evolution of the hybrid demand order flow pattern over long time horizons. The hybrid demand is the result of the mutual interaction between the e-commerce and th ...

Multi-scale ﬂuctuations of bed load transport rate over steep slope.

Christophe Ancey, Joris Heyman, Hongbo Ma

The bedload transport rate is of large fluctuation across several time scales. Understanding bedload transport fluctuation would be helpful for modeling the transport process. In this talk, we first report a multi-scale phenomenon of fluctuation of bedload ...
