Digital holographic microscopy for the cytomorphological imaging of cells under zero gravity

Christian Depeursinge, Muhammed Fatih Toy, Marcel Egli, Stéphane Richard

Digital holographic microscopy (DHM) has been gaining interest from cell biology community because of its label free nature and quantitative phase signal output. Besides, fast shutter time, image reconstruction by numerical propagation of the wave fields, ...

Explicit scheme for indoor propagation modeling based on the hybrid parabolic-integral equation method

Apostolos Sounas

An explicit scheme for wave propagation modeling of indoor environments is presented. The technique is based on the hybrid parabolic-integral equation method, which provides a correction to the parabolic equation method through a Green's function formulati ...

Differences between downscaling with spectral and grid nudging using WRF

Athanasios Nenes, Pengfei Liu

Dynamical downscaling has been extensively used to study regional climate forced by large-scale global climate models. During the downscaling process, however, the simulation of regional climate models (RCMs) tends to drift away from the driving fields. De ...

Cavitation influence on hydroacoustic resonance in pipe

François Avellan, Christophe Nicolet, Sébastien Alligné, Nicolas Ruchonnet

In pipe systems, pressure and flow fluctuations below cutoff frequency propagate as plane waves along pipes. Depending on the pipe length and propagation velocity, resonance leading to high amplitude pressure fluctuation may occur. At low pressure, cavitat ...

Cellular Dynamics and Three-Dimensional Refractive Index Distribution Studied with Quantitative Phase Imaging

Nicolas Pavillon

We present in this PhD thesis work various applications of digital holographic microscopy (DHM), an imaging technique based on coherent illumination which enables the recovery of the full complex wavefront, i.e. the amplitude and phase of a wave field whic ...

Photonic Nanojet engineering: Focal point shaping with scattering phenomena of dielectric microspheres

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We experimentally engineer Nanojets produced by dielectric spheres by varying the illumination and observe the effect with a high-resolution interference microscope (HRIM). Converging and diverging spherical wavefronts and Bessel- Gauss beams are considere ...

Pair correlations, short-range order, and dispersive excitations in the quasi-kagome quantum magnet volborthite

Henrik Moodysson Rønnow, Goran Nilsen

We present spatial and dynamic information on the s = 1/2 distorted kagome antiferromagnet volborthite, Cu3V2O7(OD)(2) center dot 2D(2)O, obtained by polarized and inelastic neutron scattering. The instantaneous structure factor, S(Q), is dominated by near ...

Forced and Self Oscillations of Hydraulic Systems Induced by Cavitation Vortex Rope of Francis Turbines

Sébastien Alligné

With economical energy market strategies based on instantaneous pricings of electricity as function of the demand or the predictions, operators harness more hydroelectric facilities to off-design operating points to cover the variations of the electricity ...

Experimental Investigations of Dam Break Flows down an Inclined Channel.

Christophe Ancey, Danilo Marra, Thomas Earl

Dam break floods on steep slopes occur in diverse settings and can encompass natural events such as mudflows and avalanches as well as the failure of manmade dams. Laboratory experiments were undertaken to investigate the dam break flows of pure water down ...
