Analysis of lock-exchange gravity currents over smooth and rough beds

Mário Jorge Rodrigues Pereira Da Franca, Claudia Adduce

Gravity currents produced by full-depth lock-release of saline water into a fresh water tank are studied focusing on the influence of the initial density of the saline mixture in the lock and the bed roughness on gravity current kinematics. Temporal evolut ...

Coordinating transport and urban planning: from ideologies to local realities

Vincent Kaufmann, Hanja-Niriana Maksim

In Europe, the idea that coordinating transportation and urban planning is a necessary condition for setting sustainable urban development into motion has spread throughout academic and professional circles. While this concern is not new, the objectives un ...

Modeling non-visual responses to light: unifying spectral sensitivity and temporal characteristics in a single model structure

Marilyne Andersen, María Lovísa Ámundadóttir, Steven W. Lockley

The discovery of a novel type of photoreceptor that mediates non-visual light responses in humans has sparked a growing interest in the role of lighting design on human health and wellbeing. Researchers have identified intensity, spectrum, duration/pattern ...

La détection de périodicités cachées

Jean-Marc Nicoletti

This thesis is a small part of the preparation of the launch of the Gaia mission, a satellite of the European Space Agency (ESA). One of the goals of the mission is to perform a classification among variable stars considering different attributes. Periodic ...

A statistical method for draft tube pressure pulsation analysis

Nicolas Ruchonnet

Draft tube pressure pulsation (DTPP) in Francis turbines is composed of various components originating from different physical phenomena. These components may be separated because they differ by their spatial relationships and by their propagation mechanis ...

Linking Speaking and Looking Behavior Patterns with Group Composition, Perception, and Performance

Daniel Gatica-Perez, Dinesh Babu Jayagopi, Dairazalia Sanchez Cortes

This paper addresses the task of mining typical behavioral patterns from small group face-to-face interactions and linking them to social-psychological group variables. Towards this goal, we define group speaking and looking cues by aggregating automatical ...

How to prove the Maxwell conjecture via spatial coupling — A proof of concept

Rüdiger Urbanke, Nicolas Macris, Andrei Giurgiu

Investigations on spatially coupled codes have lead to the conjecture that, in the infinite size limit, the average input-output conditional entropy for spatially coupled low-density parity-check ensembles, over binary memoryless symmetric channels, equals ...
