C-shells: Deployable Gridshells with Curved Beams
Mark Pauly, Francis Julian Panetta, Seiichi Eduardo Suzuki Erazo, Quentin Christian Becker, Yingying Ren, Davide Pellis
We introduce a computational pipeline for simulating and designing C-shells, a new class of planar-to-spatial deployable linkage structures. A C-shell is composed of curved flexible beams connected at rotational joints that can be assembled in a stress-fre ...
2023The imprint of galaxy mergers on satellite planes in a cosmological context
Flattened and kinematically correlated planes of dwarf satellite galaxies have been observed in the Local Volume. The slinging out of satellites during host galaxy mergers has been suggested as a formation mechanism for these peculiar structures. We statis ...
2023Probing the faint-end luminosity function of Lyman-alpha emitters at 3 < z < 7 behind 17 MUSE lensing clusters
Benjamin Yvan Alexandre Clement, Johan Richard
Context. This paper presents a study of the galaxy Lyman-alpha luminosity function (LF) using a large sample of 17 lensing clusters observed by the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT). The magnification resulting ...
Les Ulis Cedex A2023Method for flattening substrates or layers using 3d printing and etching
Niels Quack, Teodoro Graziosi, Nathanaël Restori
The present invention concerns a layer or substrate flattening method comprising the steps of: - providing a layer or substrate (1) to be flattened; - measuring a topography or surface profile of at least one area (3) of the layer or substrate to be flatte ...
2021Verification of selective laser melting heat source models with operando X-ray diffraction data
Helena Van Swygenhoven, Steven Van Petegem, Samy Hocine
The output obtained from operando X-ray diffraction experiments on Ti-6Al-4V is used to verify the accuracy of four FEM models in predicting the temperature evolution of the solidified domain, the cooling rates of the alpha and beta phases, and the influen ...
ELSEVIER2021Analysis and Transfer of Human Movement Manipulability in Industry-like Activities
Sylvain Calinon, Noémie Laure Gwendoline Jaquier
Humans exhibit outstanding learning, planning and adaptation capabilities while performing different types of industrial tasks. Given some knowledge about the task requirements, humans are able to plan their limbs motion in anticipation of the execution of ...
IEEE2020Shapes of rotating normal fluid He-3 versus superfluid He-4 droplets in molecular beams
Christoph Bostedt, Andre Al Haddad
Previous single-pulse extreme ultraviolet and x-ray coherent diffraction studies revealed that superfluid He-4 droplets obtained in a free jet expansion acquire sizable angular momentum, resulting in significant centrifugal distortion. Similar experiments ...
AMER PHYSICAL SOC2020Microstructural controls of anticrack nucleation in highly porous brittle solids
Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter
Porous brittle solids have the ability to collapse and fail even under compressive stresses. In fracture mechanics, this singular behavior, often referred to as anticrack, demands for appropriate continuum models to predict the catastrophic failure. To ide ...
NATURE PUBLISHING GROUP2020On the Volume of the John-Lowner Ellipsoid
We find an optimal upper bound on the volume of the John ellipsoid of a k-dimensional section of the n-dimensional cube, and an optimal lower bound on the volume of the Lowner ellipsoid of a projection of the n-dimensional cross-polytope onto a k-dimension ...
SPRINGER2020Early Urinary Biomarkers in Pediatric Autosomal Dominant Polycystic Kidney Disease (ADPKD): No Evidence in the Interest of Urinary Neutrophil Gelatinase-Associated Lipocalin (uNGAL)
Background: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is increasingly diagnosed during childhood by the presence of renal cysts in patients with a positive familial history. No curative treatment is available and early detection and diagnosis co ...
