Effect of pool confinement on pressures around a block impacted by plunging aerated jets
Anton Schleiss, Rafael Xavier Meriade Duarte
The erosion caused by jets issued from hydraulic structures progressively develops a confined scour-hole on the riverbed. A realistic scour assessment must consider both the influence of the air entrained when the jet plunges into the pool and the flow pat ...
National Research Council Canada2016Splitting fields of conics and sums of squares of rational functions
Given a geometrically unirational variety over an infinite base field, we show that every finite separable extension of the base field that splits the variety is the residue field of a closed point. As an application, we obtain a characterization of functi ...
Springer-Verlag2013Recent numerical developments in scrape-off-layer global fluid simulations using the GBS code
Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto
Turbulence in the scrape-off-layer (SOL) of magnetic fusion devices is one of the most outstanding issues in magnetic fusion. This open fied lines region determines the boundary condition of the core plasma and controls the plasma refueling, heat losses an ...
2013High-speed CMOS magnetic angle sensor based on miniaturized circular vertical Hall devices
Radivoje Popovic, Mirjana Banjevic
We present a high-speed CMOS integrated magnetic angle sensor consisting of two 8-contact circular vertical Hall devices (CVHD). The biasing and sensing of the Hall voltage is rotated clockwise for the first device, and counter clockwise for the second one ...
2012New Results in the Theory of Linear and Integer Programming
The polynomial Hirsch conjecture states that the vertex-edge diameter of a d-dimensional polyhedron with n facets is bounded by a polynomial in d and n. For the special case where the polyhedron is defined as the set of points satisfying a system Ax ≤ b of ...
EPFL2012Technical note: Preliminary estimation of rockfall runout zones
Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrai ...
2011OmniSIFT: Scale Invariant Features in Omnidirectional Images
We propose a method to compute scale invariant features in omnidirectional images. We present a formulation based on Riemannian geometry for the definition of differential operators on non-Euclidian manifolds that correspond to the particular form of mirro ...
2010DNA Topology
This thesis explores different aspects of DNA topology through experimental and numerical techniques. Topology is a vast mathematical field, that deals with the spatial properties of objects undergoing continuous deformations, but here it is restricted to ...
EPFL2010Sound Speed Estimation Using Wave-based Ultrasound Tomography: Theory and GPU Implementation
Martin Vetterli, Olivier Roy, Ali Hormati, Ivana Jovanovic, Reza Parhizkar
We present preliminary results obtained using a time domain wave-based reconstruction algorithm for an ultrasound transmission tomography scanner with a circular geometry. While a comprehensive description of this type of algorithm has already been given e ...

Hans Peter Herzig, Toralf Scharf, Pierre-Yves Baroni
We present a straightforward low cost liquid phase deposition method to coat arbitrary-shaped dielectric substrates with uniform electron beam sensitive polymer films. Furthermore, we investigate the use of electron beam lithography to pattern the coated p ...
