Capacitive coupled RFID tag using a new dielectric droplet encapsulation approach
No full textRadio frequency identification (RFID) is a well-known and fast-growing technology
used to identify people, animals and products. RFID tags are used to replace bar
codes in a wide range of applications, to mention just a few, retail, transportation,
logistics and healthcare.
The two main driving aspects for most of research and development projects
concerning RFID tags are the reduction of assembly costs and the downsizing of
microchips. In that respect and considering an Industry 4.0 scenario, the study of a
new assembly approach for passive and high frequency RFID tags has been proposed
and studied in this thesis.
In this new approach, which is based on the inkjet printing technology, a specifically
designed radio frequency integrated circuit (RFIC) will be delivered, inside a
liquid dielectric droplet, onto the antenna and no longer placed and oriented precisely
as it happens nowadays with pick-and-place and flip chip machines. After a landing
phase, the liquid droplet (with the encapsulated chip) will self-aligns with respect
to the contact thanks to capillary forces driven by specifically designed wetting
conditions on the substrate of the antenna. Finally, with few additional steps, the
complete RFID tag is created.
This research project brings to light a considerable simplification and a very high
potential of parallelization, compatible with large volume manufacturing methods, in
comparison to nowadays existing technologies. This may substantially drive down
the fabrication costs. An in-depth analysis of electrical performances have been
carefully undertaken and compliance with the ISO/IEC 144443 standard has been
verified. Mathematical models have been developed showing fundamental limits for
the maximum tag reading range and power requirements of the RFID reader

No full textThe Classics of the First Lorenzo de' Medici. For a New Critical Reading of Corinth
No full textopenIl presente lavoro si propone di rileggere una delle prime opere di Lorenzo de’ Medici, "Corinto", attraverso temi letterari che lo caratterizzano, tenendo presente i modelli latini, greci e italiani ai quali l’autore attinge e confrontandone altri, pertinenti ai temi analizzati. Dopo una rapida introduzione sul contesto storico in cui il poemetto si inserisce, esso viene presentato per quanto concerne il contenuto e la storia redazionale, approfondita nell’Appendice, dove si presentano inoltre i testi di riferimento. Segue dunque la nuova lettura critica. La riflessione sul concetto di classico e su Lorenzo quale autore e personaggio del poemetto conclude l’analisi.The present work aims to re-read one of Lorenzo de’ Medici’s first works, "Corinto", through the literary themes which characterize it, keeping in mind the Latin, Greek and Italian models on which the author draws and comparing others, pertinent to the themes analyzed. After a quick introduction to the historical context in which the poem fits, it is presented in terms of content and editorial history, detailed in the Appendix, where the reference texts are also presented. Thus follows the new critical reading. The reflection on the concept of classic and on Lorenzo as author and character of the poem concludes the analysis

A Florentine family in crisis: the Strozzi in the fifteenth century.
No full textPhDIn 1434 the Strozzi lineage had held a leading position in
Florentine society and government for at least one hundred and fifty
years, and was one of the largest and wealthiest of the city's
patrician lineages. The records of the catasto of 1427 and of the
scrutiny of 1433 are used to give a profile of the dominant social,
economic and political position of the Strozzi before the advent of
Medicean dominance. Their record of electoral success, and the
political and cultural leadership of influential and respected men
such as Palla di Nofri and Matteo di Simone, with other factors, put
the Strozzi amongst the greatest enemies of the victorious Medicean
regime of late 1434. The effects of political opposition and exile
on the lineage are examined both directly, through records of office-holding,
and indirectly through such indicators as marriage alliances
and household wealth. The two most prominent lines of the Strozzi
were exiled after 1434. Palla di Nofri's life and preoccupations in
his Paduan exile are examined, together with the lives of his sons;
none of these Strozzi ever returned to Florence, pursued as they were
by the enmity of the Medicean regime. The very different careers of
Filippo di Matteo and his brother Lorenzo are also examined: how they
succeeded in founding a lucrative bank in Naples, and in returning to
Florence to 'rebuild' (rifare) the position of the Strozzi lineage
there. The final decades of the century saw the Strozzi in an
economically more secure position, due substantially to the efforts
of Filippo. Except for a very small number of its members admitted
into the regime, most of the lineage is here shown to have remained
excluded from significant political office until after the fall of
the Medici regime in 1494
