Left invertibility of discrete-time output-quantized systems: the linear case with finite inputs

Autor: Dubbini, Nevio, Piccoli, Benedetto, Bicchi, Antonio

This paper studies left invertibility of discrete-time linear output-quantized systems. Quantized outputs are generated according to a given partition of the state-space, while inputs are sequences on a finite alphabet. Left invertibility, i.e. injec

Causality as a unifying approach between activation and connectivity analysis of fMRI data

Autor: Dubbini, Nevio

This paper indicates causality as the tool that unifies the analysis of both activations and connectivity of brain areas, obtained with fMRI data. Causality analysis is commonly applied to study connectivity, so this work focuses on demonstrating tha

Distributed Consensus on Set-valued Information

Autor: Fagiolini, Adriano, Dubbini, Nevio, Bicchi, Antonio

This paper focuses on the convergence of infor- mation in distributed systems of agents communicating over a network. The information on which the convergence is sought is not represented by real numbers, rather by sets of real numbers, whose possibl

Left invertibility of I/O quantized linear systems in dimension 1: a number theoretic approach

Autor: Dubbini, Nevio, Monge, Maurizio, Bicchi, Antonio

This paper studies left invertibility of discrete-time linear I/O quantized linear systems of dimension 1. Quantized outputs are generated according to a given partition of the state-space, while inputs are sequences on a finite alphabet. Left invert

An equivalent of Kronecker's Theorem for powers of an Algebraic Number and Structure of Linear Recurrences of fixed length

Autor: Dubbini, Nevio, Monge, Maurizio

After defining a notion of $\epsilon$-density, we provide for any real algebraic number $\alpha$ an estimate of the smallest $\epsilon$ such that for each $m>1$ the set of vectors of the form $(t,t\alpha,...,t\alpha^{m-1})$ for $t\in\R$ is $\epsilon$
