Digitised Newspapers – A New Eldorado for Historians? Reflections on Tools, Methods and Epistemology
Maud Ehrmann, Frédéric Clavert
The application of digital technologies to historical newspapers has changed the research landscape historians were used to. An Eldorado? Despite undeniable advantages, the new digital affordance of historical newspapers also transforms research practices ...
De Gruyter2022pyFFS: A Python Library for Fast Fourier Series Computation and Interpolation with GPU Acceleration
Martin Vetterli, Paul Hurley, Eric Bezzam, Sepand Kashani, Matthieu Martin Jean-André Simeoni
Fourier transforms are an often necessary component in many computational tasks, and can be computed efficiently through the fast Fourier transform (FFT) algorithm. However, many applications involve an underlying continuous signal, and a more natural choi ...
2022Digitised Historical Newspapers: A Changing Research Landscape (Introduction)
Maud Ehrmann, Frédéric Clavert
The application of digital technologies to newspaper archives is transforming the way historians engage with these sources. The digital evolution not only affects how scholars access historical newspapers, but also, increasingly, how they search, explore a ...
De Gruyter Oldenbourg2022Function Integration, Reconstruction And Approximation Using Rank-1 Lattices
Fabio Nobile, Giovanni Migliorati
We consider rank-1 lattices for integration and reconstruction of functions with series expansion supported on a finite index set. We explore the connection between the periodic Fourier space and the non-periodic cosine space and Chebyshev space, via tent ...
2021On Block Prediction For Learning-Based Point Cloud Compression
Touradj Ebrahimi, Evangelos Alexiou
Point clouds are among popular visual representations for immersive media. However, the vast amount of information generated during their acquisition requires effective compression for practical applications. Although relevant activities from standardizati ...
IEEE2021Basic design considerations for a frequency step-tunable electron cyclotron wave system to suppress NTMs in DEMO
Minh Quang Tran, Emiliano Fable, Hartmut Zohm, Emanuele Poli, Konstantinos Avramidis, Giovanni Tardini
An Electron Cyclotron Wave (ECW) system will be used in the European DEMO for the stabilization of Neoclassical Tearing Modes (NTMs). In order to avoid movable mirrors in the harsh environment close to the plasma and to simplify the NTM launcher integratio ...
ELSEVIER SCIENCE SA2021Simultaneous decoding of cardiovascular and respiratory functional changes from pig intraneural vagus nerve signals
Silvestro Micera, Simone Romeni, Ivo Strauss
Objective. Bioelectronic medicine is opening new perspectives for the treatment of some major chronic diseases through the physical modulation of autonomic nervous system activity. Being the main peripheral route for electrical signals between central nerv ...
IOP PUBLISHING LTD2021Hardware-oriented pruning and quantization of Deep Learning models to detect life-threatening arrhythmias
Alexandre Schmid, Lizeth Gonzalez Carabarin
Wearable solutions based on Deep Learning (DL) for real-time ECG monitoring are a promising alternative to detect life-threatening arrhythmias. However, DL models suffer of a large memory footprint, which hampers their adoption in portable technologies. Th ...
IEEE2021Fast and multiscale formation of isogeometric matrices of microstructured geometric models
Pablo Antolin Sanchez, Thibaut Hirschler
The matrix formation associated to high-order discretizations is known to be numerically demanding. Based on the existing procedure of interpolation and lookup, we design a multiscale assembly procedure to reduce the exorbitant assembly time in the context ...
SPRINGER2021Subjective and Viewport-based Objective Quality Assessment of 360-degree Videos
Pascal Frossard, Roberto Gerson De Albuquerque Azevedo
Visual distortions in processed 360-degree visual content and consumed through head-mounted displays (HMDs) are perceived very differently when compared to traditional 2D content. To better understand how compression-related artifacts affect the overall pe ...
