Engineering Casimir interactions with epsilon-near-zero materials

Miguel Camacho, Tao Gong, Benjamin Spreng +3

In this paper we theoretically demonstrate the tunability of the Casimir force both in sign and magnitude between parallel plates coated with dispersive materials. We show that thi…

ArchABM: an agent-based simulator of human interaction with the built environment. and viral load analysis for indoor air quality

Iñigo Martinez, Jan L. Bruse, Ane M. Florez-Tapia +2

Recent evidence suggests that SARS-CoV-2, which is the virus causing a global pandemic in 2020, is predominantly transmitted via airborne aerosols in indoor environments. This call…

Free Riding in Networks

Markus Kinateder, Luca Paolo Merlino

Players allocate their budget to links, a local public good and a private good. A player links to free ride on others' public good provision. We derive sufficient conditions for th…

Branching processes with resetting as a model for cell division

Arthur Genthon, Reinaldo García-García, David Lacoste

We study the Stochastic Thermodynamics of cell growth and division using a theoretical framework based on branching processes with resetting. Cell division may be split into two su…

Quantum outage probability for time-varying quantum channels

Josu Etxezarreta Martinez, Patricio Fuentes, Pedro Crespo +1

Recent experimental studies have shown that the relaxation time, , and the dephasing time, , of superconducting qubits fluctuate considerably over time. Time-varying quan…

Discharge of elongated grains from silo with rotating bottom

Kiwing To, Yi-Kai Mo, Tivadar Pongó +1

We study the flow of elongated grains (wooden pegs of length =20 mm with circular cross section of diameter =6 and 8 mm) from a silo with a rotating bottom and a circular o…

Simulation study on the fleet performance of shared autonomous bicycles

Naroa Coretti Sánchez, Iñigo Martinez, Luis Alonso Pastor +1

Rethinking cities is now more imperative than ever, as society faces global challenges such as population growth and climate change. The design of cities can not be abstracted from…

Labelling Drifts in a Fault Detection System for Wind Turbine Maintenance

Iñigo Martinez, Elisabeth Viles, Iñaki Cabrejas

A failure detection system is the first step towards predictive maintenance strategies. A popular data-driven method to detect incipient failures and anomalies is the training of n…

Forecasting VaR and ES using a joint quantile regression and implications in portfolio allocation

Luca Merlo, Lea Petrella, Valentina Raponi

In this paper we propose a multivariate quantile regression framework to forecast Value at Risk (VaR) and Expected Shortfall (ES) of multiple financial assets simultaneously, exten…

Segmentation of cell-level anomalies in electroluminescence images of photovoltaic modules

Urtzi Otamendi, Iñigo Martinez, Marco Quartulli +3

In the operation & maintenance (O&M) of photovoltaic (PV) plants, the early identification of failures has become crucial to maintain productivity and prolong components' life. Of…

Particle flow rate in silos under rotational shear

D. Hernández-Delfin, T. Pongó, K. To +2

Very recently, To et al.~have experimentally explored granular flow in a cylindrical silo, with a bottom wall that rotates horizontally with respect to the lateral wall \cite{Kiwin…

Flow in an hourglass: particle friction and stiffness matter

Tivadar Pongó, Viktória Stiga, János Török +5

Granular flow out of a silo is studied experimentally and numerically. The time evolution of the discharge rate as well as the normal force (apparent weight) at the bottom of the c…

Modeling particle-fluid interaction in a coupled CFD-DEM framework

Ilberto Fonceca, Diego Maza, Raúl Cruz Hidalgo

In this work, we present an alternative methodology to solve the particle-fluid interaction in the resolved CFDEM coupling framework. This numerical approach consists of coupling a…
