Modelling mode dependent lane discipline in hybrid traffic
Nikolaos Geroliminis, Georgios Anagnostopoulos
Time to collision (TTC) is a key indicator of human locomotion, encompassing both pedestrian and vehicular traffic. Applications of the TTC concept span a wide spectrum from safety to traffic flow dynamics. However, there exists no generic formulation for ...
2023Development of Thin Film Lithium Niobate Shear Bulk Acoustic Wave Resonators
RF MEMS piezoelectric acoustic resonators are the essential building blocks for RF filters used in RF front-end modules for wireless mobile communication due to their compact size in the MHz-GHz frequency range, high Quality factors and large relative band ...
EPFL2022ON WAVEFRONT ABERRATIONS IN ASYMMETRIC AND MULTIPLE APERTURE OPTICAL SYSTEMS
The present work deals with monochromatic wavefront aberrations in optical systems without symmetries. The treatment begins with a class of systems characterized by misaligned spherical surfaces whose behavior is analyzed using the wavefront aberration exp ...
EPFL2021The Genesis of Molecular Volcano Plots
Matthew Wodrich, Michael Markus Busch, Boodsarin Sawatlon
For the past two decades, linear free energy scaling relationships and volcano plots have seen frequent use as computational tools that aid in understanding and predicting the catalytic behavior of heterogeneous and electrocatalysts. Based on Sabatier's pr ...
2021Graph Signal Processing: Foundations and Emerging Directions [From the Guest Editors]
Dimitri Nestor Alice Van De Ville, Negar Kiyavash
The articles in this special section focus on graph signal processing. Generically, the networks that sustain our societies can be understood as complex systems formed by multiple nodes, where global network behavior arises from local interactions between ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Context Mover's Distance & Barycenters: Optimal Transport of Contexts for Building Representations
Martin Jaggi, Aymeric Daphnis Kévin Dieuleveut, Sidak Pal Singh, Andreas Hug
We present a framework for building unsupervised representations of entities and their compositions, where each entity is viewed as a probability distribution rather than a vector embedding. In particular, this distribution is supported over the contexts w ...
ADDISON-WESLEY PUBL CO2020Leveraging wafer-level manufacturing process limitations to increase large scale fused silica microlens array uniformity
Toralf Scharf, Wilfried Noell, Raoul Kirner, Jeremy Béguelin
The wafer-level production of Fused Silica microlens arrays is limited by systematic process non-uniformities. The common molten resist-reflow process with subsequent dry-etching allows for manufacturing of microlens arrays on 200 mm wafers. A thorough pro ...
SPIE-INT SOC OPTICAL ENGINEERING2019Specification of aspherical surfaces used as refractive elements in micro-optical systems
Toralf Scharf, Wilfried Noell, Jeremy Béguelin
The optical performance of refractive plano-convex microlenses is mainly related to the quality of their (a)spherical surface. An efficient tolerancing of this surface is a key step towards the manufacturing of high quality microlenses. However, we demonst ...
SPIE-INT SOC OPTICAL ENGINEERING2019Regulation of organohalide respiration
Julien Maillard, Mathilde Stéphanie Willemin
Organohalide respiration (OHR) is an anaerobic metabolism by which bacteria conserve energy with the use of halogenated compounds as terminal electron acceptors. Genes involved in OHR are organized in reductive dehalogenase (rdh) gene clusters and can be f ...
Academic Press2019Carbon Nanotube Array Based Binary Gabor Zone Plate Lenses
Diffractive zone plates have a wide range of applications from focusing x-ray to extreme UV radiation. The Gabor zone plate, which suppresses the higher-order foci to a pair of conjugate foci, is an attractive alternative to the conventional Fresnel zone p ...
