Variational reconstruction of scalar and vector images from non-uniform samples

Muthuvel Arigovindan

We address the problem of reconstructing scalar and vector functions from non-uniform data. The reconstruction problem is formulated as a minimization problem where the cost is a weighted sum of two terms. The first data term is the quadratic measure of go ...

Orbital shaker technology for the cultivation of mammalian cells in suspension

Florian Maria Wurm, David Hacker, Martin Jordan, Natalie Muller, Philippe Pierre Girard

For large-scale applications in biotechnology, cultivation of mammalian cells in suspension is an essential prerequisite. Typically, suspension cultures are grown in glass spinner flasks filled to less than 50% of the nominal volume. We propose a superior ...

Three Dimensional Frames of References Transformations using Recurrent Populations of Neurons

Aude Billard, Eric Sauser

This work investigates whether population vector coding, a distributed computational paradigm, could be a principle mechanism for performing sensorimotor and frames of reference transformations. This paper presents a multilayer neural network that can perf ...

Hierarchical Implicit Surface Joint Limits for Human Body Tracking

Pascal Fua, Raquel Urtasun, Lorna Herda

To increase the reliability of existing human motion tracking algorithms, we propose a method for imposing limits on the underlying hierarchical joint structures in a way that is true to life. Unlike most existing approaches, we explicitly represent depend ...

Cross correlations between 13C-1H dipolar interactions and 15N chemical shift anisotropy in nucleic acids

Geoffrey Bodenhausen

Two sets of cross-correlated relaxation rates involving chem. shift anisotropy and dipolar interactions have been measured in an RNA kissing complex. In one case, both the CSA and dipolar interaction tensors are located on the same nucleotide base and are ...

Intramolecular energy transfer in highly vibrationally excited methanol. III. Rotational and torsional analysis

Thomas Rizzo

We report here torsional analysis of rotationally resolved spectra of the 3 nu(1), 5 nu(1), and 6 nu(1) (OH stretch) bands of jet-cooled methanol. The upper states are reached by a double resonance excitation scheme involving the selection of single rotati ...

Method and Apparatus for Generating Halftone Images by Discrete One-to-one Dither Tile Rotation

Roger Hersch

The invention relates to a method and apparatus for automatic high-speed generation of digital angled halftone screens, specially suited for obtaining screens approximating the irrational angles which are generally required by high-quality colour reproduct ...

Intensity-Dependent Beat Frequency in a Fiberoptic Ring Laser Gyro

Luc Thévenaz

The Kerr effect causes a nonreciprocity between the two counterpropagating lightwaves in the fiber coil of a fiberoptic gyro, thus resulting in a spurious rotation signaI. For interferometric fiber gyros, a power difference as small as ten nanowatts gives ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
