Surrogate based Global Sensitivity Analysis of ADM1-based Anaerobic Digestion Model 

Trucchia, A.; Frunzo, L. (2021)
In order to calibrate the model parameters, Sensitivity Analysis routines are mandatory to rank the parameters by their relevance and fix to nominal values the least influential factors. Despite the high number of works ...

Fire-spotting generated fires. Part I: The role of atmospheric stability 

Egorova, V.; Trucchia, A.; Pagnini, G.Autoridad BCAM (2019-02)
This is the first part of two papers concerning fire-spotting generated fires. In this part we deal with the impact of macroscale factors, such as the atmospheric stability, and in the second part we deal with mesoscale ...

On the merits of sparse surrogates for global sensitivity analysis of multi-scale nonlinear problems: Application to turbulence and fire-spotting model in wildland fire simulators 

Trucchia, A.; Egorova, V.; Pagnini, G.Autoridad BCAM; Rochoux, M.C. (2019-02)
Many nonlinear phenomena, whose numerical simulation is not straightforward, depend on a set of parameters in a way which is not easy to predict beforehand. Wildland fires in presence of strong winds fall into this category, ...

Restoring property of the Michelson-Sivashinsky equation 

Trucchia, A.; Pagnini, G.Autoridad BCAM (2019)
In this paper we propose a derivation of the Michelson-Sivashinsky (MS) equation that is based on front propagation only, in opposition to the classical derivation based also on the flow field. Hence, the characteristics ...

Front Propagation in Random Media 

Trucchia, A. (2019)
This PhD thesis deals with the problem of the propagation of fronts under random circumstances. A statistical model to represent the motion of fronts when are evolving in a media characterized by microscopical randomness ...

Surrogate-based uncertainty and sensitivity analysis for bacterial invasion in multi-species biofilm modeling 

Trucchia, A.; Mattei, M.R.; Luongo, V.; Frunzo, L.; Rochoux, M.C. (2019)
In this work, we present a probabilistic analysis of a detailed one-dimensional biofilm model that explicitly accounts for planktonic bacterial invasion in a multi-species biofilm. The objective is (1) to quantify and ...

RandomFront 2.3 A physical parametrisation of fire-spotting for operational fire spread models: Implementation in WRF-Sfire and response analysis with LSFire+ 

Trucchia, A.; Egorova, V.; Butenko, A.; Kaur, I.; Pagnini, G.Autoridad BCAM (2018-12)
Fire-spotting is often responsible for a dangerous flare up in the wildfire and causes secondary ignitions isolated from the primary fire zone leading to perilous situations. The main aim of the present research to provide ...

The role of the environment in front propagation 

Trucchia, A.; Pagnini, G.Autoridad BCAM (2018-07-09)
In this work we study the role of a complex environment in the propagation of a front with curvature-dependent speed. The motion of the front is split into a drifting part and a fluctuating part. The drifting part is ...

Quasi-probability Approach for Modelling Local Extinction and Counter-gradient in Turbulent Premixed Combustion 

Pagnini, G.Autoridad BCAM; Trucchia, A. (2018-05-23)
In opposition to standard probability distributions, quasi-probability distributions can have negative values which highlight nonclassical properties of the corresponding system. In quantum mechanics, such negative values ...

Concurent multi-scale physical parametrization of fire-spotting: A study on the role of macro- and meso-scale characteristics of the system 

Egorova, V.; Trucchia, A.; Pagnini, G.Autoridad BCAM (2018)
The strong impact of wildfires in terms of lives and homes lost and of damage to ecosystems, calls for an urgent improvement in the risk management. The aim of the present research is the improvement of these software ...
