Shafranov shift correction to the Furth-Yoshikawa scaling of tokamak adiabatic compression

In 1970, Furth and Yoshikawa (1970 Phys. Fluids 13 2593-6) introduced the scalings of adiabatic plasma compression. Basically, if the shape of the external plasma boundary and the aspect ratio are preserved during the compression, then the density, kinetic ...

Spontaneous formation of ordered micro-wrinkles on a thermosensitive resist

Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio, Mohammadreza Rostami

Self-organizing patterns with micrometer-scale features are promising for applications in photonics and bioengineering. Their spontaneous formation reduces the number of required processing steps. Here, we report an approach to spontaneously form stochasti ...

Entre la rue et la roche. Réinterprétation d’une architecture locale: fragment de ville au pied de la muraille de Bellinzone

Loris Lotti

Au cœur de la ville de Bellinzone s’élève la colline de San Michele, un véritable piédestal rocheux sur lequel se dresse l’un des trois châteaux de la cité ainsi que son impressionnante muraille (Castelgrande et Murata Sforzesca). Au pied de la face nord d ...

V-band Doppler backscattering diagnostic in the TCV tokamak

Stefano Coda, Laurie Porte, Matthieu Toussaint, Pierre Lavanchy, Pedro Andres Molina Cabrera, Nicola Offeddu

A variable configuration V-band heterodyne Doppler back-scattering diagnostic has been recently made operational in the tokamak a configuration variable. This article describes the hardware setup options, flexible quasi-optical launcher antenna, data-analy ...

The Role of Anisotropy on the Volumetric Behaviour of Opalinus Clay upon Suction Change

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Alberto Minardi

An experimental investigation to analyse the anisotropic volumetric response of shaly and sandy facies of Opalinus Clay upon suction variations is presented. Obtained results demonstrate the different behaviour of the tested facies to a wetting-drying cycl ...

Dynamic crack propagation with a variational phase-field model: limiting speed, crack branching and velocity-toughening mechanisms

Jean-François Molinari, Jérémy Bleyer, Clément Pierre Mathieu Roux-Langlois

We address the simulation of dynamic crack propagation in brittle materials using a regularized phase-field description, which can also be interpreted as a damage-gradient model. Benefiting from a variational framework, the dynamic evolution of the mechani ...

Anisotropic volumetric behaviour of Opalinus Clay shale upon suction variation

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Alberto Minardi

Opalinus Clay shale is under consideration to serve as the host geomaterial for the underground storage of nuclear waste in Switzerland. Water retention behaviour and anisotropic behaviour represent two main features of this geomaterial; however, a compreh ...

Small subset sums

Gergely Ambrus

Let parallel to.parallel to be a norm in R-d whose unit ball is B. Assume that V subset of B is a finite set of cardinality n, with Sigma(v is an element of V) v = 0. We show that for every integer k with 0

Independence number of generalized Petersen graphs

Javad Ebrahimi Boroojeni

Determining the size of a maximum independent set of a graph G, denoted by alpha(G), is an NP-hard problem. Therefore many attempts are made to find upper and lower bounds, or exact values of alpha(G) for special classes of graphs. This paper is aimed towa ...

Different geometries for spin-transfer oscillators

Several geometries have recently been proposed for spin-transfer oscillators, with the purpose of optimizing the output power and the frequency dependence on the applied current, as well as minimizing the external magnetic field required to stabilize magne ...
