Light Scattering Enhancement at the Absorption Edge in Dewetting Droplets of Cyanine Dyes

Frank Nüesch, Jakob Heier, Florent Alexandre Boudoire

Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...

Velocity profiles of turbidity currents flowing over a flat bed

Giovanni De Cesare, Anton Schleiss, 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 ...

Front-crawl stroke descriptors variability assessment for skill characterisation

Kamiar Aminian, Farzin Dadashi, Grégoire Millet

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, Laurène Véronique Vuillaume, Roy Salomon, Nathan Quentin Faivre

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 ...

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 ...

Transition of optical regime in miniaturized optical systems: light interactions beyond the refraction limit

Hans Peter Herzig, Myun Sik Kim, Toralf Scharf

We investigate the transition of optical regimes of miniaturized optical systems using two canonical examples, where the refraction of light limits the system performance. A ball-lens and a solid immersion lens (SIL) are considered, whose refractive respon ...

Distinct vestibular effects on early and late somatosensory cortical processing in humans

Olaf Blanke, Christian Pfeiffer, Michiel van Elk, Fosco Bernasconi

In non-human primates several brain areas contain neurons that respond to both vestibular and somatosensory stimulation. In humans, vestibular stimulation activates several somatosensory brain regions and improves tactile perception. However, less is known ...

A wind-tunnel investigation of wind-turbine wakes in yawed conditions

Fernando Porté Agel, Majid Bastankhah

Wind-tunnel experiments were performed to study the performance of a model wind turbine and its wake characteristics in a boundary layer under different operating conditions, including different yaw angles and tip speed ratios. High-resolution particle ima ...
