Multiwavelength observations of a VHE gamma-ray flare from PKS 1510-089 in 2015

Context. PKS 1510 089 is one of only a few flat spectrum radio quasars detected in the very-high-energy (VHE, > 100 GeV) gamma-ray band. Aims. We study the broadband spectral and temporal properties of the PKS 1510 089 emission during a high gamma-ray stat ...

A novel MILP approach for simultaneous optimization of water and energy: Application to a Canadian softwood Kraft pulping mill

François Maréchal, Maziar Kermani, Zoé Périn-Levasseur

An optimization methodology based on Mixed Integer Linear Programming (MILP) has been developed for simultaneous optimization of water and energy (SOWE) in industrial processes. The superstructure integrates non-water process thermal streams and optimizes ...

Imaging magnetic vortex configurations in ferromagnetic nanotubes

Anna Fontcuberta i Morral, Dirk Grundler, Gözde Tütüncüoglu

We image the remnant magnetization configurations of CoFeB and permalloy nanotubes (NTs) using x-ray magnetic circular dichroism photoemission electron microscopy. The images provide direct evidence for flux-closure configurations, including a global vorte ...

Katabatic Flow: A Closed-Form Solution with Spatially-Varying Eddy Diffusivities

Jiannong Fang, Peter Monkewitz, Marc Parlange, Marco Giovanni Giometto

The Nieuwstadt closed-form solution for the stationary Ekman layer is generalized for katabatic flows within the conceptual framework of the Prandtl model. The proposed solution is valid for spatially-varying eddy viscosity and diffusivity (O'Brien type) a ...

Synthesis of non-isothermal water networks including process hot and cold streams

François Maréchal, Maziar Kermani

The synthesis problems of non‒isothermal water networks have received considerable attention throughout academia and industry over the last two decades because of the importance of simultaneously minimising water and energy consumption [1]. Most papers hav ...

Wind Energy Potential in Switzerland: Discovering Localized Thermo-topographic Flows and Associated Wind Resource

Varun Sharma, Michael Lehning, Franziska Gerber

In 2011, the Swiss Federal council and Parliament decided on the phase out of Switzerland’s five nuclear energy plants (BFE n.d.) and launched the “Energy Strategy 2050” which envisages a significant expansion of electricity production from renewable sourc ...

StreamFlow 1.0: an extension to the spatially distributed snow model Alpine3D for hydrological modelling and deterministic stream temperature prediction

Michael Lehning, Wolf Hendrik Huwald, Francesco Comola, Mathias Thierry Pierre Bavay, Tristan Jonas Brauchli, Aurélien Gallice

Climate change is expected to strongly impact the hydrological and thermal regimes of Alpine rivers within the coming decades. In this context, the development of hydrological models accounting for the specific dynamics of Alpine catchments appears as one ...

Hydraulic performance of stepped spillway aerators and related downstream flow features

Stéphane Christian Olivier Terrier

To protect spillways against cavitation damage, adding a small air concentration to the flow close to the invert is efficient. Aerator performance on smooth chutes was therefore well studied in terms of air entrainment and downstream air concentration deve ...

Influence of the Coriolis force on the structure and evolution of wind turbine wakes

Fernando Porté Agel, Mahdi Abkar

In this study, large-eddy simulation combined with a turbine model is used to investigate the effect of vertical wind veer associated with the Coriolis force on the structure and evolution of wind turbine wakes. In order to isolate the Coriolis effect on t ...
