Šajā kvalifikācijas darbā ir izstrādāta Mifare 1k bezkontakta karšu pārvaldīšanas lietojumprogramma datoriem ar Windows operētājsistēmu. Šī lietojumprogramma ir izveidota c# programmēšanas valodā un tā sastāv no vairākām daļām, kas veic katra savu funkciju. Pirmā daļa ir paredzēta darbinieku identificēšanai ar bezkontakta kartes palīdzību un to autorizēšanai sistēmā. Otrā daļa ir paredzēta alpīnisma torņa instruktoriem, lai tie varētu pārvaldīt alpīnisma torni un tā klientus. Klientiem tiks izsniegtas Mifare 1k bezkontakta aproces, ar kurām tos varēs identificēt un attiecīgi sākt un beigt viņu kāpienu alpīnisma tornī. Trešā daļa ir domāta administrācijas darbiniekiem, kuri pārvaldītu šīs be…

Exploiting multimodality for intelligent mobile access to pervasive services in cultural heritage sites
2010
In this chapter the role of multimodality in intelligent, mobile guides for cultural heritage environments is discussed. Multimodal access to information contents enables the creation of systems with a higher degree of accessibility and usability. A multimodal interaction may involve several human interaction modes, such as sight, touch and voice to navigate contents, or gestures to activate controls. We first start our discussion by presenting a timeline of cultural heritage system evolution, spanning from 2001 to 2008, which highlights design issues such as intelligence and context-awareness in providing information. Then, multimodal access to contents is discussed, along with problems an…
Polymer-doped UHF RFID tag for wireless-sensing of humidity
2012
Passive UHF RFID tags, beside item labelling, are also able to exploit capability of sensing the physical state of the tagged object as well as of the surrounding environment. Here a family of polymer-doped tags are proposed and fully characterized for the detection of ambient humidity. A sensitive chemical species based on PEDOT:PSS is used to dope a properly shaped slot carved into a folded-like patch tag. The communication and sensing capabilities of the radio-sensor are investigated by means of simulation and measurements showing how to control and balance above opposite requirements by dosing the quantity of sensitive material. The device could have interesting application in the asses…
Les enfants difficiles à table : conceptualisation et évolution
2022
L'objectif du présent article est de proposer un état des lieux des études récentes permettant d'offrir un cadre conceptuel et opérationnel au concept de comportement difficile à table, tout en mettant en lumière les conséquences psychologiques pour l'enfant, ainsi que les pratiques éducatives parentales associées. L'article ambitionne aussi de déterminer dans quelle mesure un enfant difficile est un mangeur à risque de développer ultérieurement des troubles du comportement alimentaire (anorexie mentale, ARFID), et quelles seraient les pistes à privilégier, en termes de guidance parentale, pour accompagner l'enfant.
Multi-agent control architecture for RFID cyberphysical robotic systems initial validation of tagged objects detection and identification using Playe…
2016
International audience; The objective of this paper is to describe and validate a multi-agent architecture proposed to control RFID Cyber-Physical Robotic Systems. This environment may contain human operators, robots (mobiles, manipulators, mobile manipulators, etc.), places (workrooms, walls, etc.) and other objects (tables, chairs, etc.). The proposed control architecture is composed of two types of agents dispatched on two levels. We find at the Organization level a Supervisory agent to allow operators to configure, manage and interact with the overall control system. At the Control level, we distinguish the Robots agents, to each robot (mobiles, manipulators or mobile manipulators) is a…
Pusaudžu izvairīgas/ierobežojošas pārtikas uzņemšanas traucējuma iezīmju, sensorā jutīguma un internalizētu uzvedības problēmu sakarības
2022
Darba mērķis ir izpētīt ARFID iezīmju, sensorā jutīguma un internalizēto uzvedības problēmu sakarības pusaudžiem. Pētījumā piedalījās 271 pusaudzis 14 – 18 gadu vecumā. Pētījumā tika izmantotas trīs aptaujas – Deviņu jautājumu ARFID aptauja, Īpaši jutīga bērna aptauja, Ahenbaha jaunieša uzvedības pašnovērtēšanas aptaujas internalizēto uzvedības problēmu skalas. Rezultāti parādīja, ka pastāv statistiski nozīmīgas pozitīvas saistības starp pusaudžu ARFID iezīmēm, sensoro jutīgumu un internalizētām uzvedības problēmām. Meitenēm tika novērotas izteiktākas ARFID iezīmes, sensorais jutīgums un internalizētas uzvedības problēmas nekā zēniem. Internalizētas uzvedības problēmu kopējie rādītāji progn…
LE NUOVE TECNOLOGIE A RADIOFREQUENZA Le applicazioni nel settore agro-alimentare
2015
L’identificazione automatica e la tracciabilità di oggetti sono tecnologie conosciute da tempo ed implementate utilizzando diverse soluzioni, quali il codice a barre, le strisce magnetiche e così via. Tutte queste tecnologie sono però accomunate da una caratteristica significativa: il loro funzionamento si basa sul contatto diretto, fisico o visivo, dell’oggetto con i dispositivi che devono garantirne l’identificazione.
RFID. La nuova frontiera della tracciabilità. Le applicazioni nel settore agro-alimentare
2015
RFId, acronimo di Radio Frequency Identification (Identificazione a Radio Frequenza), è un sistema per rilevare contenuti informativi riferiti a persone, animali ed oggetti, costituito da due parti: RFId tag (etichetta RFId) ed un lettore di RFId fisso o portatile. Quando senti parlare di RFId, e-tag (etichette elettroniche), smart label, smart dust, zigbee in realtà ci si riferisce a tanti nomi equivalenti per indicare una rivoluzione che si sta annunciando nel mondo industriale. Si tratta di microdispositivi che comunicano senza fili tra di loro, scambiandosi informazioni di identità, stato, temperatura
