Experimental study on the influence of abrupt slope changes on flow characteristics over stepped spillways

Application of stepped spillways increases the energy dissipation rate along the spillway and may reduce the dimensions of the terminal energy dissipation structure. This pronounced energy dissipation makes stepped chutes attractive under various condition ...

Measuring spatio-temporal parameters of uphill ski-mountaineering with ski-fixed inertial sensors

Kamiar Aminian, Benedikt Fasel

In this study an algorithm designed for the diagonal stride in classical cross-country skiing was adapted to compute spatio-temporal parameters for uphill ski mountaineering using a ski fixed inertial sensor. Cycle duration, thrust duration, cycle speed, c ...

Doping dependent plasmon dispersion in 2H-transition metal dichalcogenides

Helmuth Berger

We report the behavior of the charge carrier plasmon of 2H-transition metal dichalcogenides (TMDs) as a function of intercalation with alkali metals. Intercalation and concurrent doping of the TMD layers have a substantial impact on plasmon energy and disp ...

Monitoring and prediction in Early Warning Systems (EWS) for rapid mass movements

Alexis Berne, Alessio Ferrari, Dani Or, Marc Schleiss

Rapid mass movements (RMM) pose a substantial risk to people and infrastructure. Reliable and cost-efficient measures have to be taken to reduce this risk. One of these measures includes establishing and advancing the State of Practice in the application o ...

Quantifying snowfall and avalanche release synchronization: a case study

Paolo Perona, Benoît Crouzy, Betty Sovilla, Romain Forclaz

We quantify the synchronization between snowfall and natural avalanches in relation to terrain properties at the detachment zone. We analyze field statistics of 549 avalanche events in terms of slope, aspect, timing, coordinate, and release area, identifie ...

Heuristic strategies for the approximation of stability factors in quadratically nonlinear parametrized PDEs

Andrea Manzoni, Federico Negri

In this paper we present some heuristic strategies to compute rapid and reliable approximations to stability factors in nonlinear, inf-sup stable parametrized PDEs. The efficient evaluation of these quantities is crucial for the rapid construction of a pos ...

Air Entrainment in Skimming Flow on Stepped Spillways: the Effect of an Abrupt Slope Change

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Mohammad Javad Ostad Mirza

Numerous stepped spillways were built during the last decades. In particular, a stepped spillway may be integrated economically into the downstream face of a RCC gravity dam, or on valley flanks besides embankment or rockfill dams, where slope changes may ...

Geotypen : ein neues Konzept zur Optimierung geologischer Informationen für die Raumplanung

Aurèle Parriaux, Pascal Turberg

When we have to valorise the geological information for land planning or engineering applications, it is difficult to integrate the large complexity of the maps of the Swiss Geological Atlas at the scale of 1:25'000. The heterogeneity of the legends betwee ...

The Influence of the Slope Angle of the Ocean–Land Mixed Propagation Path on the Lightning Electromagnetic Fields

Keyhan Sheshyekani, Dongshuai Li

In this paper, lightning electromagnetic fields in the presence of an ocean-land mixed propagation path having different configurations are evaluated using a finite-element-based full-wave approach. The simulations are conducted considering lightning strik ...

The Biocompatibility and Anti-Biofouling Properties of Magnetic Core-Shell Fe@C NWs/AAO Nanocomposites

Mahmut Selman Sakar

Soft-magnetic core–multishell Fe@C NWs–AAO nanocomposites were synthesized using anodization, electrodeposition and low-pressure chemical vapour deposition (CVD) at 900 °C. High chemical and mechanical stability is achieved by the conversion from amorphous ...
