Recent results on Heavy-Ion induced reactions of interest for 0νββ decay

2019

An updated overview of recent results on Heavy-Ion induced reactions of interest for neutrinoless double beta decay is reported in the framework of the NUMEN project. The NUMEN idea is to study heavy-ion induced Double Charge Exchange (DCE) reactions with the aim to get information on the nuclear matrix elements for neutrinoless double beta (0νββ) decay. Moreover, to infer the neutrino average masses from the possible measurement of the half- life of 0νββ decay, the knowledge of the nuclear matrix elements is a crucial aspect. Uma visão geral atualizada dos resultados recentes sobre reações induzidas por íons pesados ​​de interesse para o decaimento beta duplo sem neutrinos é relatada na es…

Overview and accomplishments of the Borexino experiment

2015

International audience; The Borexino experiment is running at the Laboratori del Gran Sasso in Italy since 2007. Its technical distinctive feature is the unprecedented ultralow background of the inner scintillating core, which is the basis of the outstanding achievements accumulated by the experiment. In this talk, after recalling the main features of the detector, the impressive solar data gathered so far by the experiment will be summarized, with special emphasis to the most recent and prominent result concerning the detection of the fundamental pp solar neutrino flux, which is the direct probe of the engine mechanism powering our star. Such a milestone measurement puts Borexino in the un…

#IoRestosenzaCasa. La condizione delle persone senza dimora durante la pandemia

2020

To reach the identification of the serious marginality, in a moment of pandemic, is not a very simple operation considering the amplification of inequalities throughout the national territory, but also internationally. The Covid-19 pandemic has severely tested the resilience of States and social and health care systems. It is inevitable that the most affected by the lockdown, which marked the country from March to May 2020, were the homeless. When we talk about homeless people, issues, questions, difficulties arise immediately. The first limit is to have the count of the phenomenon in numerical terms. Data on the presence of homeless people in Italy date back to 2014 and estimate 50,724 hom…

A distributed data storage and retrieval scheme in unattended WSNs using Homomorphic Encryption and secret sharing

2009

Many data storage schemes have been proposed in the past for keeping dependable data storage, but they are not designed for Unattended Wireless Sensor Networks (UWSNs). When applying these schemes to UWSNs, most of them have limitations such as high storage requirement, transmission cost, and not resilient to a large number of node compromises. To address the problem of data storage, transmission cost, and resilience of node compromise in UWSNs, we propose a novel Homomorphic Encryption and Homomorphic Secret Sharing based scheme (HEHSS) to accomplish the goals of confidentiality, resilience to node compromises, reliability, and efficiency of storage and transmission. Our scheme exploits th…

Home as a Base for a Well-Lived Life: Comparing the Capabilities of Homeless Service Users in Housing First and the Staircase of Transition in Europe

2020

Nussbaum’s Central Capabilities refer to the elements of a well-lived life, and many adults who experience homelessness are deprived of these capabilities. The study aim was to investigate whether service users experience different homeless services as affording or constraining capabilities. We conducted semi-structured interviews with homeless service users (n = 77) in Housing First (HF) and staircase services (SS) in eight European countries. We used thematic analysis to identify three themes: autonomy and dependency, the relational impact of living arrangements, and community interaction and stigma. While SS participants were able to address their bodily integrity and health, their highe…

Structure and agency in capabilities-enhancing homeless services: Housing first, housing quality and consumer choice

2021

The capabilities approach, a framework for understanding and measuring inequality, stipulates that equality is best understood as the freedom to do and be within a particular context. Homelessness has been referred to as a situation of ‘capabilities deprivation’, and the extent to which homeless services restore or enhance capabilities is of increasing interest. As part of a large, eight-country study of homelessness in Europe, we examined the extent to which adults with histories of perceived the services they receive as capabilities-enhancing. We collected data at two time points: baseline (nt1 = 565) and follow-up (nt2 = 399). Measures included perceived capabilities, choice and housing …

Comparison of housing first and traditional homeless service users in eight european countries: Protocol for a mixed methods, Multi-site study

2020

Background Homeless services expend considerable resources to provide for service users’ most basic needs, such as food and shelter, but their track record for ending homelessness is disappointing. An alternative model, Housing First, reversed the order of services so that homeless individuals are offered immediate access to independent housing, with wraparound supports but no treatment or abstinence requirements. Although the evidence base for Housing First’s effectiveness in ending homelessness is robust, less is known about its effectiveness in promoting recovery. Objective The objective of this research is to compare rehabilitation- and recovery-related outcomes of homeless services us…

Designing Touchless Gestural Interfaces for Public Displays

Nell’ultimo decennio, molti autori hanno studiato la possibilità di utilizzare le interfacce a gesti come strumento innovativo per supportare l’interazione con i computer. Inoltre, le recenti innovazioni tecnologiche hanno permesso di installare display interattivi in ambienti privati e pubblici. Tuttavia, l’interattività di tali display è spesso basata sull’uso di touchscreen, mentre tecnologie come i dispositivi Kinect-like vengono adottate molto più raramente, soprattutto se si considera l’ambito dei display pubblici. Al giorno d’oggi, l’opportunità di studiare le interfacce touchless per i display pubblici è diventata concreta, e rappresenta il campo di studio di diversi ricercatori. L’…

Hybrid Observer for Indoor Localization with Random Time-of-Arrival Measurments

2018

In this work an indoor position estimation algorithm will be proposed. The position will be measured by means of a sensor network composed by fixed beacons placed on the indoor environment and a mobile beacon mounted on the object to be tracked. The mobile beacon communicates with all the fixed beacons by means of ultra wide-band signals, and the distance between them is computed by means of time of flight techniques. Moreover, inertial measurements will be used when the position measurements are not available. Two main problems will be considered in the proposed architecture: the fact that the beacons work with a lower update rate than the IMU, and that the mobile beacon can comunicate wit…

HLPV Identication in wireless ad hoc networks

2013

Hybrid systems are dynamical systems consisting of components with con- tinuous and discrete behavior and thus they have required a new hybrid systems and control theory that has been developed in the past years and is still an active research topic. Motivated by a practical example, the tra c ow in wireless ad hoc network model, we derive Hybrid LPV modeling and identi cation techniques. Finally we show simulation results of o line identi cation and possible future algorithms.
