Experimental investigation on the moment-rotation performance of pultruded FRP web-flange junctions

This paper aims to present an experimental investigation on the behavior of web-flange junctions (WFJs) rotational stiffness of pultruded fiber-reinforced polymer composites (FRP). Channels and I-sections were tested using a simple set-up, which was develo ...

Vehicle Having a High Clearing Capability

Thomas Estier

The invention relates to a vehicle which includes at least four wheels and a base. Said wheels are attached in pairs at the base via connections and form a bogie consisting of a pair of wheels. Said bogies are rotatably hinged onto the base such that the p ...

Digital Phase Reconstruction via Iterative Solutions of Transport-of-Intensity Equation

Michaël Unser, Emrah Bostan, Stamatios Lefkimmiatis, Emmanuel Augustin Julien Froustey

We develop a variational algorithm for reconstructing phase objects from a series of bright field micrographs. Our mathematical model is based on the transport-of-intensity equation (TIE), which links the phase of a complex field to the axial derivative of ...

Marker-free phase nanoscopy

Pierre Magistretti, Christian Depeursinge, Nicolas Pavillon, Pierre Marquet, Pascal Jourdain, Daniel Boss, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We introduce a microscopic method that determines quantitative optical properties beyond the optical diffraction limit and allows direct imaging of unstained living biological specimens. In established holographic microscopy, complex fields are measured us ...

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 ...

Complex index refraction tomography with sub ?/6-resolution

Christian Depeursinge, Nicolas Pavillon, Yann Jérôme Michel Pascal Cotte

The present invention discloses a method to improve the image resolution of a microscope. This improvement is based on the mathematical processing of the complex field computed from the measurements with a microscope of the wave emitted or scattered by the ...

Realistic 3D coherent transfer function inverse filtering of complex fields

Christian Depeursinge, Daniel Boss, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte, Cristian Arfire, Shanshan Kou

We present a novel technique for three-dimensional (3D) image processing of complex fields. It consists in inverting the coherent image formation by filtering the complex spectrum with a realistic 3D coherent transfer function (CTF) of a high-NA digital ho ...
