Constraints on violation of Lorentz invariance from atmospheric showers initiated by multi-TeV photons

Sergey Sibiryakov

Parameterizing hypothetical violation of Lorentz invariance at high energies using the framework of effective quantum field theory, we discuss its effect on the formation of atmospheric showers by very-high-energy gamma rays. In the scenario where Lorentz ...

Multi-code analysis of scrape-off layer filament dynamics in MAST

Paolo Ricci, Fabio Riva

Four numerical codes are employed to investigate the dynamics of scrape-off layer filaments in tokamak relevant conditions. Experimental measurements were taken in the MAST device using visual camera imaging, which allows the evaluation of the perpendicula ...

Front-crawl stroke descriptors variability assessment for skill characterisation

Kamiar Aminian, Grégoire Millet, Farzin Dadashi

The goal of this article is to character ise front-crawl swimming skill based on variability pattern of technique descriptors. Nine national level and nine recreational swimmers performed three 300 m trials in a 50 m outdoor pool, at 70%, 80% and 90% of th ...

Enhanced discriminability for nonbiological motion violating the two-thirds power law

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Laurène Véronique Vuillaume

The two-thirds power law describes the relationship between velocity and curvature in human motor movements. Interestingly, this motor law also affects visual motion perception, in which stimuli moving according to the two-thirds power law are perceived to ...

Velocity profiles of turbidity currents flowing over a flat bed

Anton Schleiss, Giovanni De Cesare, Sabine Chamoun

Turbidity currents are the main source of suspended sediment transport in reservoirs and thus one of the main causes of sedimentation. One of the techniques used to avoid reservoir sedimentation is through venting of turbidity currents. In the framework of ...

Critical heat flux: Performance of R1234yf, R1234ze and R134a in an aluminum multi-minichannel heat sink at high saturation temperatures

John Richard Thome

In this paper, new saturated critical heat flux (CHF) values at medium-to-high saturation temperatures are presented for an aluminum multi-minichannel test section. Among the possible working fluids, R134a and the low GWP refrigerants R1234yf and R1234ze h ...

Supremizer stabilization of POD-Galerkin approximation of parametrized steady incompressible Navier-Stokes equations

Alfio Quarteroni, Gianluigi Rozza, Andrea Manzoni

In this work we present a stable proper orthogonal decomposition (POD)-Galerkin approximation for parametrized steady incompressible Navier-Stokes equations with low Reynolds number. Supremizers solutions are added to the reduced velocity space in order to ...
