Optimal tracking strategies in a turbulent flow

Autor: Chiara Calascibetta, Luca Biferale, Francesco Borra, Antonio Celani, Massimo Cencini

Publikováno v: Communications Physics, Vol 6, Iss 1, Pp 1-10 (2023)

Abstract Pursuing a drifting target in a turbulent flow is an extremely difficult task whenever the searcher has limited propulsion and maneuvering capabilities. Even in the case when the relative distance between pursuer and target stays below the t

The Role of Data in Model Building and Prediction: A Survey Through Examples

Autor: Marco Baldovin, Fabio Cecconi, Massimo Cencini, Andrea Puglisi, Angelo Vulpiani

Publikováno v: Entropy, Vol 20, Iss 10, p 807 (2018)

The goal of Science is to understand phenomena and systems in order to predict their development and gain control over them. In the scientific process of knowledge elaboration, a crucial role is played by models which, in the language of quantitative

What ecological factors shape species-area curves in neutral models?

Autor: Massimo Cencini, Simone Pigolotti, Miguel A Muñoz

Publikováno v: PLoS ONE, Vol 7, Iss 6, p e38232 (2012)

Understanding factors that shape biodiversity and species coexistence across scales is of utmost importance in ecology, both theoretically and for conservation policies. Species-area relationships (SARs), measuring how the number of observed species

Prolate microswimmer in surface gravity waves

Autor: Francesco Michele Ventrella, Filippo De Lillo, Guido Boffetta, Massimo Cencini, Jean-Luc Thiffeault, Nimish Pujara

Planktonic microorganisms immersed in a fluid interact with the ambient flow, altering their trajectories. In surface gravity waves, a common goal for microswimmers is vertical migration. By modeling phytoplankton as spheroidal bodies with a certain

Taming Lagrangian chaos with multi-objective reinforcement learning

Autor: Chiara Calascibetta, Luca Biferale, Francesco Borra, Antonio Celani, Massimo Cencini

Publikováno v: The European Physical Journal E. 46

We consider the problem of two active particles in 2D complex flows with the multi-objective goals of minimizing both the dispersion rate and the energy consumption of the pair. We approach the problem by means of Multi Objective Reinforcement Learni

Orientation of swimmers in turbulent flows

Autor: Filippo De Lillo, Matteo Borgnino, Guido Boffetta, Kristian Gustafsson, Bernhard Mehlig, Massimo Cencini

Many phytoplankters are able to swim, and are thus not passively transported by the flow. Although usually weak, ocean turbulence can affect the motion of one-celled organisms in nontrivial ways. It is known that an ellipsoidal body can be rotated by

Suspended particles can significantly alter the fluid properties and, in particular, can modify the transition from laminar to turbulent flow. We investigate the effect of heavy particle suspensions on the linear stability of the Kolmogorov flow by m
