A PRACTICAL ANALYTIC METHOD FOR CALCULATING pi(x)
In this paper we give a description of a practical analytic method for the computation of pi(x), the number of prime numbers
American Mathematical Society2017CMOS-Compatible PureGaB Ge-on-Si APD Pixel Arrays
Edoardo Charbon, Mahdi Aminian
Pure gallium and pure boron (PureGaB) Ge-on-Si photodiodes were fabricated in a CMOS compatible process and operated in linear and avalanche mode. Three different pixel geometries with very different area-to-perimeter ratios were investigated in linear arr ...
Ieee-Inst Electrical Electronics Engineers Inc2016Rigidity of equality cases in Steiner’s perimeter inequality
Characterization results for equality cases and for rigidity of equality cases in Steiner’s perimeter inequality are presented. (By rigidity, we mean the situation when all equality cases are vertical translations of the Steiner symmetral under considerati ...
2014Design of heliostat fields using a multi-objective evolutionary algorithm
The paper discusses the interest of the multi-objective optimization approaches for the design of complex energy systems and the basics of the original evolutionary algorithm used. The specific problems linked to the design of the concentrators of solar to ...
2006Propriétés magnétiques de nanostructures de cobalt adsorbées
This thesis reports results on magnetic properties of supported cobalt nanostructures. The nanostructures were grown on single crystal metal surface by Molecular Beam Epitaxy in an Ultra High Vacuum chamber. Our experimental setup is based on two in situ m ...
EPFL2004The remarkable difference between surface and step atoms in the magnetic anisotropy of two-dimensional nanostructures
Harald Brune, Stefano Rusponi, Philipp Buluschek, Nicolas Weiss, Laurent Claude
The original magnetic properties of nanometre-sized particles are due to the distinct contributions of volume, surface and step atoms. To disentangle these contributions is an ongoing challenge of materials science. Here we introduce a method enabling the ...
