First neutron imaging experiments at the CROCUS zero-power reactor

The steady decline of neutron imaging (NI) facilities, exacerbated by the closure of several research reactors such as Orphée (LLB, France) and BER (HZB, Germany), has increased the importance of leveraging existing reactors for NI applications. Zero-power research reactors offer a low-cost and flexible platform for student training, materials research and development, and proof-of-principle studies that can support larger neutron facilities. Previously, no dedicated NI beamline was available at the EPFL ze

Euclid Quick Data Release (Q1): IV. From images to multi-wavelength catalogues: The Euclid MERge processing function★

The Euclid satellite is an ESA mission that was launched in July 2023. Euclid is working in its regular observing mode with the target of observing an area of 14 000 deg2 with two instruments, the Visible Camera (VIS) and the Near IR Spectrometer and Photometer (NISP) down to IE = 24.5 mag (10 σ) in the Euclid Wide Survey. Ground-based imaging data in the ugriz bands complement the Euclid data to enable photo-z determination and VIS PSF modelling for weak lensing analysis. Euclid investigates the distance-r

First wall particle fluxes and Be erosion in high-performance JET-ITER baseline plasmas

In next step large fusion devices with a tungsten (W) first wall such as ITER, impurity control will be a challenge to avoid strong core radiation from highly ionized metals. Here we analyse the deuterium (D) fluxes impacting on the beryllium (Be) first wall limiters and the resulting surface erosion in high-performance neon (Ne) seeded ITER-baseline plasmas with up to 35 MW heating power in JET tokamak. Visible cameras are used to quantify the fluxes using the spectroscopic S/XB method at the regions of st

Euclid Quick Data Release (Q1): XXXVIII. Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars

The slitless spectroscopy mode of the Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid telescope has enabled efficient spectroscopy of objects within a large field of view. Nevertheless, the relatively low spectral resolution, overlapping spectra, and contamination pose challenges to source classification and redshift determination using the NISP spectra alone. In this work, we present a large and homogeneous sample of bright quasars identified from the Euclid Quick Data Release (Q1), co

Euclid Quick Data Release (Q1): XXXVI. Galaxy shapes and alignments in the cosmic web

Galaxy morphologies and shape orientations are expected to correlate with their large-scale environments, since they grow by accreting matter from the cosmic web and are subject to interactions with other galaxies. We extracted cosmic filaments in projection from the Euclid Quick Data Release 1 (covering 63.1 deg2) at 0.5 < z < 0.9 in tomographic slices of 170 comoving h −1 Mpc using photometric redshifts. Galaxy morphologies are accurately retrieved thanks to the excellent imaging resolution of the visible

Software of TTool: a supervised AI-assisted Visual Pose Detector for AR Wood-working

TTool is developed at the Laboratory for Timber Construction (director: Prof.Yves Weinand) with the support of the EPFL Center for Imaging and the SCITAS, at EPFL, Lausanne, Switzerland. The project is part of the Augmented Carpentry Research. It is an open-source AI-powered and supervised 6DoF detector for monocular camera. It is developed in C++ and for UNIX systems to allow accurate end-effectors detection during wood-working operations such as cutting, drilling, sawing and screwing with multiple tools.

LenslessPiCam: A Hardware and Software Platform for Lensless Computational Imaging with a Raspberry Pi

Martin Vetterli

Lensless imaging seeks to replace/remove the lens in a conventional imaging system. The earliest cameras were in fact lensless, relying on long exposure times to form images on the other end of a small aperture in a darkened room/container (camera obscura). The introduction of a lens allowed for more light throughput and therefore shorter exposure times, while retaining sharp focus. The incorporation of digital sensors readily enabled the use of computational imaging techniques to post-process and enhance r

Airborne and mobile LiDAR, which sensors for which application?

Jan Skaloud

The UAV mapping industry expanded tremendously during the last five years. Thanks to miniaturization, automation and advertising, this technology may give a wrong impression that mapping of certain quality is as simple as clicking few buttons on a PC. Moreover, with a large and continuously increasing offer of hardware and software, the identification of the right tools is not easy, especially when aiming at certain standard. In this respect, the mapping with LiDAR is more delicate than with a camera due to

Temporal Super-Resolution Microscopy Using a Hue-Encoded Shutter

Sylvain Calinon, Michael Stefan Daniel Liebling, Emmanuel Pignat, Christian Jaques

Limited time-resolution in microscopy is an obstacle to many biological studies. Despite recent advances in hardware, digital cameras have limited operation modes that constrain frame-rate, integration time, and color sensing patterns. In this paper, we pr ...

The effect of the upcoming TCV divertor upgrade on the distribution of neutrals and the onset of detachment is studied using 2D transport code simulations. The divertor upgrade is centered around the installation of a gas baffle to form a divertor chamber ...

Presentation attack detection in voice biometrics

Recent years have shown an increase in both the accuracy of biometric systems and their practical use. The application of biometrics is becoming widespread with fingerprint sensors in smartphones, automatic face recognition in social networks and video-based applications, and speaker recognition in phone banking and other phone-based services. The popularization of the biometric systems, however, exposed their major flaw --- high vulnerability to spoofing attacks. A fingerprint sensor can be easily tricked

Towards Automatic Train Operation for long distance services: State-of-the art and challenges

Daniel Emery

The Automatic Train Operation of a metro line is not so difficult to implement: almost no junction or crossing between lines, rolling stock homogeneity, double track operation, relatively low speed, very simple station track layout, mostly rubber-mounted, and specific site continuously fenced with no level crossing. Tunnels and platform screen doors complete the picture to prevent almost totally the presence of an obstacle or a person on the tracks. But how can Automatic Train Operation for a metro line be
