Sabine Süsstrunk, Roger Hersch, Mahmut Sami Arpa

We present a method for synthesizing high reliefs, a sculpting technique that attaches 3D objects onto a 2D surface within a limited depth range. The main challenges are the preservation of distinct scene parts by preserving depth discontinuities, the fine ...

Improving signal to noise of current mode circuits by a cross-coupled current mirror topology

Catherine Dehollain

A cross-coupled current mirror topology is presented. This topology increases the gain of a circuit that amplifies a pair of differential currents without increasing its power dissipation. An example circuit employing this current mirroring technique is pr ...

The second order pullback equation

Bernard Dacorogna, Olivier Kneuss, Gyula Csató

Let f, g be two closed k-forms over R-n. The pullback equation studies the existence of a diffeomorphism phi : R-n -> R-n such that phi*(g) = f. We prove two types of results. The first one sharpens some of the existing regularity results. The second one d ...

Integrable G-strands on semisimple Lie groups

Tudor Ratiu, François Gay-Balmaz

The present paper derives systems of partial differential equations that admit a quadratic zero curvature representation for an arbitrary real semisimple Lie algebra. It also determines the general form of Hamilton's principles and Hamiltonians for these s ...

Free form deformation techniques applied to 3D shape optimization problems

Alfio Quarteroni, Gianluigi Rozza, Anwar Koshakji

The purpose of this work is to analyse and study an efficient parametrization technique for a 3D shape optimization problem. After a brief review of the techniques and approaches already available in literature, we recall the Free Form Deformation parametr ...

An improved method for measuring muon energy using the truncated mean of dE/dx

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The measurement of muon energy is critical for many analyses in large Cherenkov detectors, particularly those that involve separating extraterrestrial neutrinos from the atmospheric neutrino background. Muon energy has traditionally been determined by meas ...

Application of Legendrian Foliations in Differential Flatness Problems

Philippe Müllhaupt, Basile Graf

Instances of control systems are presented for which dynamical feedback linearizability can be assessed from differential forms of highest relative degree after some “contact” transformation has been applied. This bypasses the need to find a polynomial dif ...

On the approximation of stability factors for general parametrized partial differential equations with a two-level affine decomposition

Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila

A new approach for computationally efficient estimation of stability factors for parametric partial differential equations is presented. The general parametric bilinear form of the problem is approximated by two affinely parametrized bilinear forms at diff ...
