A review of RFID based solutions for indoor localization and location-based classification of tags
No full textWireless communication systems are very used for indoor localization of items. In particular, two main application field can be identified. The former relates to detection or localization of static items. The latter relates to real-time tracking of moving objects, whose movements can be reconstructed over identified timespans. Among the adopted technologies, Radio-Frequency IDentification (RFID), especially if based on cheap passive RFID tags, stands out for its affordability and reasonable efficiency. This aspect makes RFID suitable for both the above-mentioned applications, especially when a large number of objects need to be tagged. The reason lies in a suitable trade-off between low cost for implementing the position sensing system, and its precision and accuracy. However, RFID-based solutions suffer for limited reading range and lower accuracy. Solutions have been proposed by academia and industry. However, a structured analysis of developed solutions, useful for further implementations, is missing. The purpose of this paper is to highlight and review the recently proposed solutions for indoor localization making use of RFID passive tags. The paper focuses on both precise and qualitative location of objects. The form relates to (i) the correct position of tags, namely mapping their right position in a 2D or 3D environment. The latter relates to the classification of tags, namely the identification of the area where the tag is regardless its specific position
Family associationism and disabilities. Approaches and intervention strategies. A scoping review
No full textThis contribution intends to investigate the phenomenon of associationism of families of children with disabilities through a Scoping Review which has set itself, among its main objectives, that of identifying the approaches and support strategies adopted by the families of the associations. The results are in continuity with the first part of the study presented in a previous work by the author (****) which had the purpose of studying the roles, motivations and purposes of associations of families of children with disabilities, offering interesting suggestions and factors for reflection also for this article.The results described below urge special pedagogy to undertake research trajectories that turn the spotlight on the evolving pedagogical processes within families of children with disabilities, with particular attention to the associative dimension. The approaches of empowerment and resilience as well as coping and parent to parent support strategies attribute a strategic role to the family in its plurality of voices, identities, needs and desires which deserve to be adequately investigated
Children with Hearing Disabilities during the Pandemic. Challenges and Perspectives of Inclusion
No full textThe COVID-19 has dramatically increased the inequalities of the opportunitiesto education and health services of the children with disabilities. The datacollected from international agencies between 2020 and 2021 demonstrate thedanger of further rising the risk of exclusion of children with disabilitiesespecially in developing countries. The marginalization of people with sensorydisabilities during the Pandemic have further expanded compared to the pre-COVID situation. The article aims to investigate the barriers that children withhearing disabilities have encountered in accessing socio-educational andrehabilitation services and reflect on the importance of social support flexiblyfrom different local actors. In this perspective, the Center of Attention forCommunication, Hearing and Language of the Central American UniversityJosé Simeón Cañas of El Salvador provides educational and rehabilitationservice aimed to children with hearing disabilities transforming theirmethodologies and practices. Based on this analysis, perspectives of action andresearch will be envisaged to plan the future starting from the lessons learned
Influence of scour on dynamic impedances of bridge shallow foundations
No full textMany bridges in earthquake-prone countries cross waterways and have foundations in riverbeds, and thus are exposed to flood, which may cause scour and a change of the bridge dynamics. The present study illustrates a modeling strategy for investigating numerically the influence of scour on the dynamic behaviour of bridges with scoured shallow foundations. The proposed strategy is based on the evaluation of the impedance functions of a massless rigid foundation resting on an elastic half-space under increasing depths of scour. The derived impedance functions are used to evaluate the effects of scour on the dynamic behaviour of a Soil-Foundation-Structure system representative of a bridge pier. In particular, the changes in the fundamental vibration period due to scour are investigated. The results of the study can be used for developing vibration-based scour detection techniques and for investigating the seismic response of scoured bridges

No full textConverting a food oven into a thermal sanitizer for Personal Protective Equipment against COVID-19: Computational Fluid Dynamics simulation
No full textCOVID-19 brought several management problems, and among these surely the topic of Personal Protective Equipment (PPE) turned out to be crucial. Indeed, in the light of mandatory measurements adopted by governments both for private individuals and companies, their demand has rapidly increased, thus generating shortages, increased waste and unbalanced prices. In response to that, many industrial fields offered their tools and know-how for trying to partly face this issue, and in this paper part of a solution of this kind is presented. Specifically, it is meant the redesign of a food oven produced by an Italian company operating in the food sector (Nilma S.p.A.) for thermal sanitization against the virus in question. In this paper, the simulation of the temperature distribution inside the chamber is simulated, with subsequent experimental validation at 95°C
Out of the Storm. A Design Education Multi-Methodological Approach on the Topic of Migrations
No full textMigrants, asylum seekers and refugees are just some of the terms used to indicate people that leave their homes for many different, and often painful, reasons to go to foreign and some- times hostile countries. The long journey that migrants must un- dertake and their stay in reception facilities are just some of the problems that they have to face. These and many other delicate aspects of a migrant’s life have been the main topic of the product design lab at the University of San Marino. Migration appears to be just one of the more significant issues in the political, economic and cultural reflections within the current historical context, but it may be taken as an example of how a design lab can approach a social topic. The paper focuses in particular on the overview of a multimethodological approach – told through the project of the students– based on Design Thinking and Lateral Thinking. The mix of these two methodologies leads students to design and learn along the consolidated path of Design Thinking but with the un- known and unexpected intervention of Lateral Thinking. Thank to this approach, students can learn how to address social issues as they forge their civic consciousness

Factors affecting the growth of academic oriented spin-offs
No full textAcademic spin-offs are companies created by one or more members of a research laboratory with the purpose of commercializing the obtained results or the technologies produced within the university. During the last two decades, academic spin-offs have received increasing attention from both researchers and practitioners, however there are few studies in the literature regarding the factors that foster its growth (Ferretti et al., 2020). Based on these premises, this chapter aims to investigate more thoroughly the growth phase of an academic spin-off’s life-cycle, focusing in particular on the drivers that influence its growth. Moreover, a focus on the academic spin-off phenomenon in the food sector is provided. The methodology adopted is that of literature review, combining two different approaches: the bibliometric analysis and the keywords analysis
