Toward a Dynamic Threshold for Quality-Score Distortion in Reference-Based Alignment

Marco Mattavelli, Claudio Paolo Alberti, Ana Angelica Hernandez Lopez

The intrinsic high entropy metadata, known as quality scores, are largely the cause of the substantial size of sequence data files. Yet, there is no consensus on a viable reduction of the resolution of the quality score scale, arguably because of collatera ...

Optimized Quantization in Distributed Graph Signal Filtering

Pascal Frossard, Isabela Cunha Maia Nobre

Distributed graph signal processing algorithms require the network nodes to communicate by exchanging messages in order to achieve a common objective. These messages have a finite precision in realistic networks, which may necessitate to implement message ...

Reconciling Being in-Control vs. Being Helped for the Execution of Complex Movements in VR

Ronan Boulic, Bruno Herbelin, Thibault Serge Mario Porssut

Performing motor tasks in virtual environments is best achieved with motion capture and animation of a 3D character that participants control in real time and perceive as being their avatar in the virtual environment. A strong Sense of Embodiment (SoE) for ...

Graph-based Transform Coding with Application to Image Compression

Pascal Frossard, Ntorina Thanou, Giulia Fracastoro

In this paper, we propose a new graph-based coding framework and illustrate its application to image compression. Our approach relies on the careful design of a graph that optimizes the overall rate-distortion performance through an effective graph-based t ...

Multi-slice passband bSSFP for human and rodent fMRI at ultra-high field

Rolf Gruetter, Ileana Ozana Jelescu, Rodrigo Araujo Fraga Da Silva, Olivier Benoit Thomas Reynaud

Balanced steady-state free precession (bSSFP) can be used as an alternative to gradient-echo (GE) EPI for BOLD functional MRI when image distortions and signal drop-outs are severe such as at ultra-high field. However, 3D-bSSFP acquisitions have distinct d ...

3D laser shock peening as a way to improve geometrical accuracy in selective laser melting

Roland Logé, Nikola Kalentics, Andreas Burn, Michael Cloots

One of the major drawbacks of selective laser melting (SLM) is the accumulation of tensile residual stresses (TRS) in the surface and subsurface zones of produced parts which can lead to cracking, delamination, geometrical distortions, and a decrease in fa ...

Using an amplitude analysis to measure the photon polarisation in B -> K pi pi gamma decays

Olivier Schneider, Frédéric Blanc, Violaine Bellée, Preema Rennee Pais

A method is proposed to measure the photon polarisation parameter.. in b. s. transitions using an amplitude analysis of B. Kpp. decays. Simplified models of the Kpp system are used to simulate B+. K+ p -p+. and B0. K+ p -p0. decays, validate the amplitude ...

Analysis and Comparison of Notch Filter and Capacitor Voltage Feedforward Active Damping Techniques for LCL Grid-Connected Converters

Francisco Daniel Freijedo Fernández, Enrique Rodriguez Diaz

The use of LCL filters is a well-accepted solution to attenuate the harmonics created by the pulsewidth modulation. However, inherently LCL filters have a resonance region where the unwanted harmonics are amplified, which can compromise stability. Several ...

Computational rule-based approach for corner correction of non-Manhattan geometries in mask aligner photolithography

Toralf Scharf, Wilfried Noell, Chen Yan, Raoul Kirner, Andreas Vetter

In proximity mask aligner photolithography, diffraction of light at the mask pattern is the predominant source for image shape distortions such as line end shortening and corner rounding. One established method to mitigate the impact of diffraction is opti ...
