Evolution of critical buckling conditions in imperfect bilayer shells through residual swelling

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla, Dong Yan, Anna Lee

We propose and investigate a minimal mechanism that makes use of differential swelling to modify the critical buckling conditions of elastic bilayer shells, as measured by the knockdown factor. Our shells contain an engineered defect at the north pole and ...

RENORMALIZATION AND BLOW-UP FOR WAVE MAPS FROM S-2 x R TO S-2

Sohrab Mirshams Shahshahani

We construct a one parameter family of finite time blow-ups to the co-rotational wave maps problem from S-2 x R to S-2, parameterized by nu is an element of (1/2, 1]. The longitudinal function u(t, alpha) which is the main object of study will be obtained ...

Measurement of the cosmic ray energy spectrum with IceTop-73

Matthias Wolf, Shirit Cohen, Sofia Vallecorsa, Mathieu Ribordy, Xiaoxia Bai

We report on the measurement of the all-particle cosmic ray energy spectrum with the IceTop air shower array in the energy range from 1.58 PeV to 1.26 EeV. The IceTop air shower array is the surface component of the IceCube Neutrino Observatory at the geog ...

Background studies for acoustic neutrino detection at the South Pole

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The detection of acoustic signals from ultra-high energy neutrino interactions is a promising method to measure the flux of cosmogenic neutrinos expected on Earth. The energy threshold for this process depends strongly on the absolute noise level in the ta ...

IceCube sensitivity for low-energy neutrinos from nearby supernovae

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

This paper describes the response of the IceCube neutrino telescope located at the geographic south pole to outbursts of MeV neutrinos from the core collapse of nearby massive stars. IceCube was completed in December 2010 forming a lattice of 5160 photomul ...

Search for relativistic magnetic monopoles with the AMANDA-II neutrino telescope

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present the search for Cherenkov signatures from relativistic magnetic monopoles in data taken with the AMANDA-II detector, a neutrino telescope deployed in the Antarctic ice cap at the Geographic South Pole. The non-observation of a monopole signal in ...

Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II

Shirit Cohen, Mathieu Ribordy, Levent Demirörs, Xiaoxia Bai

The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be u ...

La Suisse dans une économie globalisée de la connaissance

Dominique Foray, Stéphane Lhuillery

Rapport préparé pour l'étude intitulée "Où en est la Suisse dans l'économie du savoir? Pôle d'excellence et pôle de croissance", commandée par l'Office Fédéral de la Formation Professionnelle et de la Technologie (OFFT) et le Secrétariat d'Etat à l'Educati ...

Vieillissement et fiabilité des parcs de poteaux bois des réseaux de lignes aériennes

Yann Benoit

The reliability of new overhead electric and telecommunication lines depends principally on the quality of their support structures. These structures are generally made of wood, metal or concrete. The complexity of a natural substance such as wood requires ...
