Human body sensing: A pervasive approach by implanted RFID tags
2011
Starting from the physical evidence that passive RFID systems may be used as self-sensing devices, the feasibility of human monitoring by means of implanted tags is here investigated. The key parameters to master with the purpose to enhance the sensitivity of the implanted radiosensor have been theoretically analyzed and numerically applied to a specific medical problem, i.e. the continuous monitoring of liver cancer evolution. Preliminary experimental results with simplified phantoms corroborate the analysis.
Passive UHF RFID antennas for sensing applications: Principles, methods, and classifcations
2013
UHF passive radio-frequency identification technology is rapidly evolving from simple labeling of things to wireless pervasive sensing. A remarkable number of scientific papers demonstrate that objects in principle can have their physical properties be remotely tracked and monitored all along their life cycle. The key background is a new paradigm of antenna design that merges together the conventional communication issues with more-specific requirements about sensitivity to time-varying boundary conditions. This paper presents a unified review of the state of the art of the tag-as-sensor problem. Particular care is taken to formalize the measurement indicators and the communication and sens…
Pervasive body sensing: Implanted RFID tags for vascular monitoring
2010
Beside the common logistic usages of the Radio Frequency Identification (RFID) technology, one of the most innovative and promising applications is the possibility to process the backscattering signals to detect additional information about the target, such as its state and its evolution, without any specific embedded sensor or local power supply. The rationale of this idea lies in the clear dependence of the tag's input impedance and reflectivity on the physical and geometrical features of a real target. When the object where the tag is attached on undergoes some changes along with the time, the tag's electrical features also change and these variations can be remotely detected by the read…
"I RIFLESSI STRATEGICI ORGANIZZATIVI E CONTABILI DEI PRINCIPI CONTABILI INTERNAZIONALI NELLE IMPRESE BANCARIE"
2008
Questo lavoro fornisce una prima ricognizione degli effetti che l’adozione dei principi contabili internazionali da parte delle imprese bancarie ha comportato, da un punto di vista sia strettamente contabile sia organizzativo. In particolare, sono stati oggetto di analisi i principi che disciplinano il trattamento contabile e la disclosure delle voci di bilancio di natura finanziaria, e quindi i principi IAS 32, IAS 39 e IFRS 7. Nella prima parte del lavoro sono state esposte le principali novità introdotte da questi principi, dando particolare rilievo al criterio del fair value ed al diverso trattamento previsto per gli strumenti derivati rispetto alla precedente prassi contabile. Nella se…

La riflessione sulla discriminazione nei confronti delle comunità ROM dimostrano che tre sono i bisogni fondamentali: casa, istruzione e lavoro; gli stessi condivisi da un terzo della popolazione delle città del Sud. La ricerca suggerisce che non vi sarà fine della discriminazione se non si chiuderanno i "campi" e non si avvieranno politiche serie di inclusione sociale.

RFID passive gas sensor integrating carbon nanotubes
2011
Carbon nanotube (CNT) composites are sensitive to the presence of gases due to their high surface-to-volume ratio and hollow structure that are well suited for gas molecule absorption and storage. Such sensing capability is here integrated with UHF RF identification (RFID) technology to achieve passive and low-cost sensors, remotely readable. CNT film (buckypaper) is used as a localized variable resistive load integrated into a tag antenna, which becomes able to transduce the presence of hazardous gas in the environment, ammonia in this case, into a change of its electromagnetic features. The dynamic range and the hysteresis of the radio sensor are investigated by simulations, equivalent ci…
Il progetto “Oltre l’orizzonte: contro-narrazioni dai margini al centro”
2020
Il contributo descrive il progetto europeo OLTRE, acronimo di “Oltre l’orizzonte: Contro-narrazioni dai margini al centro”, è un progetto cofinanziato dalla Commissione europea, in particolare dal DG Affari Interni (Fondo per la Sicurezza Interna - Programma per l’Empowerment della Società Civile). OLTRE nasce con la finalità precipua di contribuire alla prevenzione dei fenomeni di radicalizzazione islamica sul territorio italiano, principalmente attraverso una campagna di comunicazione online. Per prevenire la radicalizzazione è necessario ridurre la vulnerabilità dei soggetti ritenuti “a rischio”, nel nostro caso specifico i giovani italiani con background migratorio di fede musulmana.
BALDONE OBSERVATORY IN THE CIRCLES OF TIME
2019
1957 – The first laboratory building, known as the White House, was built near Baldone on the Riekstu hill, in the territory of the next Observatory. 01.01.1958 – The Astronomy Sector was separated from the Institute of Physics and commenced independent activi- ty as the Laboratory of Astrophysics at the Latvian Acade- my of Sciences (LAS). In 1967, with the decision of the Presidium of the Latvian SSR LAS the Laboratory of As- trophysics was transformed into the Radioastrophysic Ob- servatory at LAS. Under the leadership of the first director, Janis Ikaunieks, an instrumental observation base develops – a 1.2m Schmidt telescope was installed in 1966 for opti- cal observations. The project …
Estimation of sea surface temperature from SEVIRI data: algorithm testing and comparison with AVHRR products
2006
Three surface temperature (ST) algorithms for Spinning Enhanced Visible and InfraRed Imager (SEVIRI) data are developed and tested. A general split window algorithm for ST estimation, a sea surface temperature (SST) algorithm and a nonlinear algorithm (NLSST) developed for SEVIRI data. The test was carried out by comparing SEVIRI data with two types of data: (a) in situ and (b) obtained with the NLSST algorithm applied to Advanced Very High Resolution Radiometer (AVHRR). The field campaign was carried out over sea using a thermal radiometer. The algorithms were applied to SEVIRI images in coincidence with the field campaign and the results show an rms error lower than 0.7 K. The comparison …
