The Physics of Sustainability: Material and Power Constraints for the Long Term
José Halloy, Petros Chatzimpiros, François Graner +1
Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energ…
Beyond 2050: From deployment to renewal of the global solar and wind energy system
Joseph Le Bihan, Thomas Lapi, José Halloy
The global energy transition depends on large-scale photovoltaic (PV) and wind power deployment. While 2050 targets suggest a transition endpoint, maintaining these systems beyond…
Modeling Technological Deployment and Renewal: Monotonic vs. Oscillating Industrial Dynamics
Joseph Le Bihan, Thomas Lapi, José Halloy
This study proposes a new model based on a classic S-curve that describes deployment and stabilization at maximum capacity. In addition, the model extends to the post-growth platea…
Cool Pavements
Martin Hendel
Cool pavements designate alternative pavements designed to reduce their contribution to urban heating. Urban heating generally refers to the sensible heat exchanged with the atmosp…
Cartographie du confort thermique au sein d'une cours d'{é}cole parisienne : couplage de mesures microclimatiques fixes et mobiles
Ghid Karam, Maïlys Chanial, Maxime Chaumont +2
Climate change will result in more frequent, more intense and longer-lasting heat waves by 2050. As part of its Climate Plan and its resilience strategy, the City of Paris is deplo…
The Oasis Project: UHI mitigation strategies applied to Parisian schoolyards
Ghid Karam, Martin Hendel, Bobée Cécilia +3
Paris is experimenting and implementing strategies to increase the capital's resilience and promote climate change adaptation. Major heatwaves have been hitting the French Capital…
Physical and geographic analysis of the urban cooling potential
Martin Hendel, Parison Sophie, Royon Laurent
The performance of a number of urban cooling techniques has been thoroughly studied by the scientific community. However, decision-makers lack the tools to spatialize their deploym…
Thermal and microclimatic behavior of OASIS schoolyard paving materials
Ghid Karam, Maïlys Chanial, Arnaud Grados +2
As part of its Resilience Strategy, the City of Paris' OASIS program aims to contribute ot its adaptation to heatwaves and climate change by transforming schoolyards into climate s…
Hearing the shape of an arena with spectral swarm robotics
Leo Cazenille, Nicolas Lobato-Dauzier, Alessia Loi +7
Swarm robotics relies on robots with minimal sensing and computation that achieve self-organization at the level of the collective to address a variety of tasks. Yet swarm robotics…
The thermoelectric conversion efficiency problem: Insights from the electron gas thermodynamics close to a phase transition
I. Khomchenko, A. Ryzhov, F. Maculewicz +10
The bottleneck in modern thermoelectric power generation and cooling is the low energy conversion efficiency of thermoelectric materials. The detrimental effects of lattice phonons…
An energy-based macroeconomic model validated by global historical series since 1820
Herve Bercegol, Henri Benisty
Global historical series spanning the last two centuries recently became available for primary energy consumption (PEC) and Gross Domestic Product (GDP). Based on a thorough analys…
Is the Past Determined?
Hervé Zwirn
In a recent paper, I argued against backward in time effects used by several authors to explain delayed choice experiments. I gave an explanation showing that there is no physical…
Acoustic streaming generated by sharp edges: the coupled influences of liquid viscosity and acoustic frequency
Chuanyu Zhang, Xiaofeng Guo, Laurent Royon +1
Acoustic streaming can be generated around sharp structures, even when the acoustic wavelength is much larger than the vessel size. This sharp-edge streaming can be relatively inte…
Thermodynamics of animal locomotion
E. Herbert, H. Ouerdane, Ph. Lecoeur +2
Muscles are biological actuators extensively studied in the frame of Hill's classic empirical model as isolated biomechanical entities, which hardly applies to a living organism su…
Unveiling of the mechanisms of acoustic streaming induced by sharp edges
Chuanyu Zhang, Xiaofeng Guo, Laurent Royon +1
Acoustic waves can generate steady streaming within a fluid owing to the generation of viscous boundary layers near walls, of typical thickness . In microchannels, the acoustic…
Vortex elongation in outer streaming flows
Seyed Amir Bahrani, Nicolas Périnet, Maxime Costalonga +2
We study the secondary time-averaged flow (streaming) generated by an oscillating cylinder immersed within a fluid, under high amplitude forcing so that inertial effects are signif…
A criterion for the pinning and depinning of an advancing contact line on a cold substrate
Rémy Herbaut, Julien Dervaux, Philippe Brunet +2
The influence of solidification on the spreading of liquids is addressed in the situation of an advancing liquid wedge on a cold substrate at , of infinite thermal condu…
Modelling zebrafish collective behaviours with multilayer perceptrons optimised by evolutionary algorithms
Leo Cazenille, Nicolas Bredeche, José Halloy
Collective movements are pervasive behaviours among social organisms and have led to the development of many models. However, modelling animal trajectories and social interactions…
Evolutionary optimisation of neural network models for fish collective behaviours in mixed groups of robots and zebrafish
Leo Cazenille, Nicolas Bredeche, José Halloy
Animal and robot social interactions are interesting both for ethological studies and robotics. On the one hand, the robots can be tools and models to analyse animal collective beh…
Non-linear impedance spectroscopy applied to thermoelectric measurements: beyond the ZT estimation
Etienne Thiébaut, François Pesty, Christophe Goupil +2
Thermoelectric measurement of the dimensionless zT parameter requires multiple physical quantities to be measured, therefore there is great interest to find an experimental setup c…
How to Blend a Robot within a Group of Zebrafish: Achieving Social Acceptance through Real-time Calibration of a Multi-level Behavioural Model
Leo Cazenille, Yohann Chemtob, Frank Bonnet +4
We have previously shown how to socially integrate a fish robot into a group of zebrafish thanks to biomimetic behavioural models. The models have to be calibrated on experimental…
