Proof of a conjecture by Gazeau et al. using the Gould-Hopper polynomials

Olivier Lévêque

We provide here some probabilistic interpretations of the generalized binomial distributions proposed by Gazeau et al. ["Generating functions for generalized binomial distributions," J. Math. Phys. 53, 103304 (2012)]. In the second part, we prove the "stro ...

Status of the EU 170 GHz/2 MW/CW Coaxial Cavity Gyrotron for ITER: The Dummy Gun Experiment

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Ioannis Pagonakis

A mock-up gun has been manufactured as exact replica of the refurbishment first prototype EU 170 GHz/2MW/CW coaxial cavity gyrotron, but without emitter ring in order to validate the voltage standoff stability. The experimental results of the mock-up gun t ...

Labelling Game for Twitter Streams

Valérian Hanser

The main goal of this project is to build a mean and to populate a database with correct information regarding some decided pairings. This database will then be compared to the results of algorithms that process the same pairings, which provides a way to a ...

Performance evaluation of two state of the art DVC codecs

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

The performance of existing DVC codecs is still lacking relative to that of H.264 and work is being carried out in order to close this gap. The authors of this paper have been and still are involved in the development of two DVC codecs respectively, the pe ...

On the essential dimension of cyclic p-groups

Let p be a prime number, let K be a field of characteristic not p, containing the p-th roots of unity, and let r >= 1 be an integer. We compute the essential dimension of Z/p(r) Z over K (Theorem 4.1). In particular, i) We have edℚ(ℤ/8ℤ)=4, a result which ...

A new REM conjecture

Véronique Gayrard

We introduce here a new universality conjecture for levels of random Hamiltonians, in the same spirit, as the local REM conjecture made by S. Mertens and H. Bauke. We establish our conjecture for a wide class of Gaussian and non-Gaussian Hamiltonians, whic ...

Characterization of equilibrium measures for critical reversible Nearest Particle Systems

We show that for critical reversible attractive Nearest Particle Systems all equilibrium measures are convex combinations of the upper invariant equilibrium measure and the point mass at all zeros, provided the underlying renewal sequence possesses moments ...

Noise-enhanced computation in a model of a cortical column

Wulfram Gerstner, Julien Mayor

Varied sensory systems use noise in order to enhance detection of weak signals. It has been conjectured in the literature that this effect, known as stochastic resonance, may take place in central cognitive processes such as memory retrieval of arithmetica ...

NANOINGENEERING OF SIN MEMBRANES USING FIB

Jürgen Brugger, Christian Santschi, Marc Antonius Friedrich van den Boogaart, Nao Takano

Applications of thin SixNy membranes may be found in miscellaneous fields such as MEMS and NEMS as well as biotechnology. FIB is an excellent tool in order to realize nano-structures on membranes achieving the ultimate limits and rapid prototyping. ...

Sur quelques inclusions différentielles de premier et de deuxième ordre

Gisella Croce

The principal subject of this thesis is the study of some Dirichlet problems related to differential inclusions of first and second order. We have studied the two following problems : where E ⊂ R2×2 is a compact isotropic set and where We show some existen ...
