Dispatch-aware Optimal Planning of Active Distribution Networks including Energy Storage Systems

The thesis develops a planning framework for ADNs to achieve their dispatchability by means of ESS allocation while ensuring a reliable and secure operation of ADNs. Second, the framework is extended to include grid reinforcements and ESSs planning. Finall ...

Social NCE: Contrastive Learning of Socially-aware Motion Representations

Alexandre Massoud Alahi, Yuejiang Liu

Learning socially-aware motion representations is at the core of recent advances in multi-agent problems, such as human motion forecasting and robot navigation in crowds. Despite promising progress, existing representations learned with neural networks sti ...

Dispatch-aware planning of energy storage systems in active distribution network

Mario Paolone, Sidi-Rachid Cherkaoui, Ji Hyun Yi

This paper proposes a procedure for the optimal siting and sizing of energy storage systems (ESSs) within active distribution networks (ADNs) hosting a large amount of stochastic distributed renewable energy resources. The optimization objective is to mini ...

Effect of task conditions on human hand pose selection strategies in bimanual fine manipulation tasks

Many manipulations in human everyday activities rely on the collaboration of our two hands. Bimanual fine manipulation tasks are particularly demanding as precise coordination among fingers of both hands is required. Yet, despite the abundant degrees of fr ...

Resting brain dynamics at different timescales capture distinct aspects of human behavior

Dimitri Nestor Alice Van De Ville, Raphaël Pierre Liégeois

Linking human behavior to resting-state brain function is a central question in systems neuroscience. In particular, the functional timescales at which different types of behavioral factors are encoded remain largely unexplored. The behavioral counterparts ...

Towards an Adaptive Upper Limb Rehabilitation Game with Tangible Robots

Pierre Dillenbourg, Friedhelm Christoph Hummel, Pablo Maceira Elvira, Wafa Monia Benkaouar Johal, Maximilian Jonas Wessel, Ayberk Özgür, Louis Pierre Faucon, Arzu Güneysu Özgür, Andéol Geoffroy Cadic-Melchior

A key feature of a successful game is its ability to provide the player with an adequate level of challenge. However, the objective of difficulty adaptation in serious games is not only to maintain the player’s motivation by challenging, but also to ensure ...

Drosophila melanogaster cloak their eggs with pheromones, which prevents cannibalism

Yury Tsybin, Laure Menin, Konstantin Nagornov

Oviparous animals across many taxa have evolved diverse strategies that deter egg predation, providing valuable tests of how natural selection mitigates direct fitness loss. Communal egg laying in nonsocial species minimizes egg predation. However, in cann ...

Sexual conflict drives male manipulation of female postmating responses in Drosophila melanogaster

Laurent Keller, Brian Dennis Hollis

In many animals, females respond to mating with changes in physiology and behavior that are triggered by molecules transferred by males during mating. In Drosophila melanogaster, proteins in the seminal fluid are responsible for important female postmating ...

Common and unique strategies of male killing evolved in two distinct Drosophila symbionts

Bruno Lemaitre, Toshiyuki Harumoto

Male killing is a selfish reproductive manipulation caused by symbiotic bacteria, where male offspring of infected hosts are selectively killed. The underlying mechanisms and the process of their evolution are of great interest not only in terms of fundame ...

Evidence for biological roots in the transgenerational transmission of intimate partner violence

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Vandana Veenit, Basira Salehi, Guillaume Poirier, Cristina Marquez Vega, Xavier Fontana

Intimate partner violence is a ubiquitous and devastating phenomenon for which effective interventions and a clear etiological understanding are still lacking. A major risk factor for violence perpetration is childhood exposure to violence, prompting the p ...

Decentralized polling with respectable participants

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Kévin Clément Huguenin

We consider the polling problem in a social network: participants express support for a given option and expect an outcome reflecting the opinion of the majority. Individuals in a social network care about their reputation: they do not want their vote to b ...

On Non-cooperative Location Privacy: A Game-theoretic Analysis

Jean-Pierre Hubaux, Julien Freudiger, David C. Parkes

In mobile networks, authentication is a required primitive of the majority of security protocols. However, an adversary can track the location of mobile nodes by monitoring pseudonyms used for authentication. A frequently proposed solution to protect locat ...

An application of advanced spatio-temporal formalisms to behavioural ecology

Stefano Spaccapietra, Christine Parent

There is great potential for the development of many new applications using data on mobile objects and mobile regions. To promote these kinds of applications advanced data management techniques for the representation and analysis of mobility-related data a ...

Border Games in Cellular Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj, Diego Dufour

In each country today, cellular networks operate on carefully separated frequency bands. This separation is imposed by the regulators of the given country to avoid interference between these networks. But, the separation is only valid within the borders of ...

Spatial navigation in geometric mazes : a computational model of rodent behavior

Navigation is defined as the capability of planning and performing a path from the current position towards a desired location. Different types, or strategies, of navigation are used by animals depending on the task they are trying to solve. Visible goals ...

The Complex Facets of Reputation and Trust

Karl Aberer, Wojciech Galuba, Zoran Despotovic

Trust and reputation systems have proven to be essential to enforcing cooperative behavior in peer-to-peer networks. We briefly describe the current approaches to building reputation systems: social networks formation, probabilistic estimation and game the ...
