Cococcioni, M.; Rossi, F.; Ruffaldi, E.; Saponara, S. Fast Approximations of Activation Functions in Deep Neural Networks when using Posit Arithmetic. Sensors 2020, 20, 1515

With the increasing real-time constraints being put by the automotive scenario on the use of Deep Neural Networks (DNNs), there is the need to review information representation. A very challenging path is to employ an encoding that allows a fast...

Zambella Grazia, et al. "Dynamic whole-body control of unstable wheeled humanoid robots." IEEE Robotics and Automation Letters 4.4 (2019): 3489-3496.

Control of two-wheeled humanoid robots poses several challenges due to the unstable dynamics of their mobile base and the coupling between the upper and lower body dynamics. The problem is often faced in the literature with methods based on the...

This article presents a system for soft human–robot handshaking, using a soft robot hand in conjunction with a lightweight and impedance-controlled robot arm. Using this system, we study how different factors influence the perceived naturalness, and...

L. Fiaschi, M. Cococcioni. Numerical Asymptotic Results in Game Theory Using Sergeyev’s Infinity Computing, International Journal of Unconventional Computing (IJUC), pp. 1-25(1) 2018.

ABSTRACT Prisoner's Dilemma (PD) is a widely studied game that plays an important role in Game Theory. This paper aims at extending PD Tournaments to the case of infinite, finite or infinitesimal payoffs using Sergeyev's Infinity Computing (IC). By...

Abstract: In this paper we consider a resource allocation problem for multi-user MIMO non orthogonal multiple access (MU-MIMO-NOMA) downlink transmissions. Under the NOMA paradigm, users are organized in clusters of strong/weak pair and our aim is to...

Decoration of Porous Silicon with Gold Nanoparticles via Layer-by-Layer Nanoassembly for Interferometric and Hybrid Photonic/Plasmonic (Bio)sensing

Abstract Gold nanoparticle layers (AuNPLs) enable the coupling of morphological, optical, and electrical properties of gold nanoparticles (AuNPs) with tailored and specific surface topography, making them exploitable in many bioapplications (e.g.,...
