Pedestrian flows in bounded domains with obstacles
Benedetto Piccoli, Andrea Tosin
In this paper we systematically apply the mathematical structures by time-evolving measures developed in a previous work to the macroscopic modeling of pedestrian flows. We propose…
Solution of Maxwell's equations on a de Sitter background
Donato Bini, Giampiero Esposito, Roberto Valentino Montaquila
The Maxwell equations for the electromagnetic potential, supplemented by the Lorenz gauge condition, are decoupled and solved exactly in de Sitter space-time studied in static sphe…
Time-evolving measures and macroscopic modeling of pedestrian flow
Benedetto Piccoli, Andrea Tosin
This paper deals with the early results of a new model of pedestrian flow, conceived within a measure-theoretical framework. The modeling approach consists in a discrete-time Euler…
A note on stability conditions for planar switched systems
Moussa Balde, Ugo Boscain, Paolo Mason
This paper is concerned with the stability problem for the planar linear switched system , where the real matrices $A_1,A_2\in \R^{2\times 2}…
Chirplet approximation of band-limited, real signals made easy
J. M Greenberg, Laurent Gosse
In this paper we present algorithms for approximating real band-limited signals by multiple Gaussian Chirps. These algorithms do not rely on matching pursuit ideas. They are hierar…
Hydrodynamic correlations in the translocation of biopolymer through a nanopore: theory and multiscale simulations
Maria Fyta, Simone Melchionna, Sauro Succi +1
We investigate the process of biopolymer translocation through a narrow pore using a multiscale approach which explicitly accounts for the hydrodynamic interactions of the molecule…
The general relativistic Poynting-Robertson effect
Donato Bini, Robert T. Jantzen, Luigi Stella
The general relativistic version is developed for Robertson's discussion of the Poynting-Robertson effect that he based on special relativity and Newtonian gravity for point radiat…
Electrocardiogram of the Mixmaster Universe
Donato Bini, Christian Cherubini, Andrea Geralico +1
The Mixmaster dynamics is revisited in a new light as revealing a series of transitions in the complex scale invariant scalar invariant of the Weyl curvature tensor best represente…
Mesoscopic lattice Boltzmann modeling of flowing soft systems
Roberto Benzi, Sergio Chibbaro, Sauro Succi
A mesoscopic multi-component lattice Boltzmann model with short-range repulsion between different species and short/mid-ranged attractive/repulsive interactions between like-molecu…
Capillary filling with randomly coated walls
Fabiana Diotallevi, Andrea Puglisi, Antonio Lamura +1
The motion of an air-fluid interface through an irregularly coated capillary is studied by analysing the Lucas-Washburn equation with a random capillary force. The pinning probabil…
Capillary filling with pseudo-potential binary Lattice-Boltzmann model
S. Chibbaro
We present a systematic study of capillary filling for a binary fluid by using a mesoscopic lattice Boltzmann model for immiscible fluids describing a diffusive interface moving at…
Combustion dynamics in steady compressible flows
S. Berti, D. Vergni, A. Vulpiani
We study the evolution of a reactive field advected by a one-dimensional compressible velocity field and subject to an ignition-type nonlinearity. In the limit of small molecular d…
Evidence of thin-film precursors formation in hydrokinetic and atomistic simulations of nano-channel capillary filling
S. Chibbaro, L. Biferale, F. Diotallevi +6
We present hydrokinetic Lattice Boltzmann and Molecular Dynamics simulations of capillary filling of high-wetting fluids in nano-channels, which provide clear evidence of the forma…
Front pinning in capillary filling of chemically coated channels
F. Diotallevi, L. Biferale, S. Chibbaro +2
The dynamics of capillary filling in the presence of chemically coated heterogeneous boundaries is investigated, both theoretically and numerically. In particular, by mapping the e…
Gravitational waves about curved backgrounds: a consistency analysis in de Sitter spacetime
Donato Bini, Salvatore Capozziello, Giampiero Esposito
Gravitational waves are considered as metric perturbations about a curved background metric, rather than the flat Minkowski metric since several situations of physical interest can…
Gravitational induction
Donato Bini, Christian Cherubini, Carmen Chicone +1
We study the linear post-Newtonian approximation to general relativity known as gravitoelectromagnetism (GEM); in particular, we examine the similarities and differences between GE…
Quantized current blockade and hydrodynamic correlations in biopolymer translocation through nanopores: evidence from multiscale simulations
Massimo Bernaschi, Simone Melchionna, Sauro Succi +2
We present a detailed description of biopolymer translocation through a nanopore in the presence of a solvent, using an innovative multi-scale methodology which treats the biopolym…
Universal intermittent properties of particle trajectories in highly turbulent flows
ICTR, :, A. Arneodo +27
We present a collection of eight data sets, from state-of-the-art experiments and numerical simulations on turbulent velocity statistics along particle trajectories obtained in dif…
Lattice Boltzmann simulations of capillary filling: finite vapour density effects
F. Diotallevi, L. Biferale, S. Chibbaro +3
Numerical simulations of two-dimensional capillary filling using the pseudo-potential lattice Boltzmann model for multiphase fluids are presented, with special emphasis on the role…
Computational aspects and applications of a new transform for solving the complex exponentials approximation problem
Piero Barone
Many real life problems can be reduced to the solution of a complex exponentials approximation problem which is usually ill posed. Recently a new transform for solving this problem…
A new transform for solving the noisy complex exponentials approximation problem
Piero Barone
The problem of estimating a complex measure made up by a linear combination of Dirac distributions centered on points of the complex plane from a finite number of its complex momen…

Piero Barone
Pencils of Hankel matrices whose elements have a joint Gaussian distribution with nonzero mean and not identical covariance are considered. An approximation to the distribution of…
