An Optimized Spline-Based Registration of a 3D CT to a Set of C-Arm Images

We have developed an algorithm for the rigid-body registration of a CT volume to a set of C-arm images. The algorithm uses a gradient-based iterative minimization of a least-squares measure of dissimilarity between the C-arm images and projections of the C ...

Cavitation Bubble Dynamics inside Liquid Drops in Microgravity

Mohamed Farhat, Nicolas Dorsaz, Claude Nicollier, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

We report a fundamental study of single cavitation bubbles inside quasi-spherical water drops produced in microgravity (42nd ESA parabolic flight campaign, 8th ESA student parabolic flight campaign). High-speed imaging revealed implications of isolated, fi ...

INTERACTION OF A CAVITATION BUBBLE WITH A SPHERICAL FREE SURFACE

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

The dynamic of a cavitation bubble inside a water drop is investigated in microgravity in order to analyze the interaction between the collapsing bubble and a quasispherical free surface. Tests are carried in the frame of the 42nd parabolic flight campaign ...

Removing Ocular Artifacts from EEG Signals Using Adaptive Filtering and ARMAX Modeling

Gelareh Mohammadi

EEG signal is one of the oldest measures of brain activity that has been used vastly for clinical diagnoses and biomedical researches. However, EEG signals are highly contaminated with various artifacts, both from the subject and from equipment interferenc ...

The Euclidean k-Distance Transformartion in Arbitrary Dimensions - a Separable Implementation

Olivier Cuisenaire

The signed k-distance transformation (k-DT) computes the k nearest prototypes from each location on a discrete regular grid within a given D dimensional volume. We propose a new k-DT algorithm that divides the problem into D 1-dimensional problems and comp ...

Contactless electrochemical actuator for precise sampling on microchip

Martinus Gijs, Lynda Metref, Daniel Berdat

The scope of this work has been the design of a mechanical actuator in polydimethylsiloxane (PDMS) / glass for precise liquid sampling, based on the electrochemical generation of O2. The device is composed of two chambers separated by a PDMS membrane. In t ...

Understanding the Simulation of Mobility Models with Palm Calculus

Jean-Yves Le Boudec

The simulation of mobility models such as the random waypoint often cause subtle problems, for example the decay of average speed as the simulation progresses, a difference between the long term distribution of nodes and the initial one, and sometimes the ...

Parallel unfolding and visualization of curved surfaces extracted from large three-dimensional volumes

Roger Hersch

Although many three-dimensional (3D) medical imaging visualization methods exist, 3D volume slicing remains the most commonly used technique for visualizing medical data from modalities such as CT, MRI, and PET. We propose to extend the possibilities of ob ...

Hot Tear formation and coalescence observations in organic alloys

Michel Rappaz, Jean-Marie Drezet, Piero Daniele Grasso

Hot tear formation has been observed during the solidification of a succinonitrile–acetone (SCN-acetone) alloy by pulling the columnar dendrites in the transverse direction with a stick. It is observed that the cracking of the mushy zone (hot tears) always ...
