A Smart Contract Based Recommender System
2019
Nowadays information available on the World Wide Web has reached unprecedented growth and it makes difficult for users to find the most relevant for them. In order to alleviate such issue, Recommender Systems (RSs) have been proposed to collect opinions and preferences about a set of items, process such preferences and build a personalized information access. While the most part of current RSs exploit centralized architecture to provide the service, in this manuscript we propose an alternative approach for building a general purpose RSs that provides to users with more transparent and decentralized rating strategy. Indeed, the proposed framework is built on top of a Distributed Ledger techn…
El fundamento liberal del derecho a la intimidad
2021
T: The right to privacy is configured as a ?retaining wall? against State interference into the private sphere of people?s life. Throughout this work we will try to expose the philosophical-liberal foundations that have led us to what is now conceived as the ?right to privacy?.
Consideraciones sobre la cláusula irph a la luz de sus antecedentes y de la doctrina consolidada del tribunal de justicia de la union europea
2021
By issuing its judgment of March 3, 2020, the Court of Justice of the European Union (CJEU) has terminated the last episode in the evolution of the IRPH index to which almost a tenth of mortgages have been referring. in Spain, compared to the rest that the Euribor takes as a reference, declaring in essence that consumers will be able to go to court to declare the abusiveness of the clause that the aforementioned index contains in the deeds of constitution of the mortgage. To understand the scope of the current situation, it is convenient to consider even briefly what the IRPH consists of and the consequences that its application has entailed for the affected consumer borrowers, taking into …
El consentimiento en el proceso penal : ¿un oxímoron?
2021
We are involved in a moment of deep changes in Criminal Procedure due, among other reasons, to the permanent expansion of Criminal Law. Legislative modifications have taken place one another over the world and they have led to a functional reformulation of the role played by the protagonists of Criminal Procedure. These changes have not finished yet and the future is still to come, but new elements are already emerging: the consent of the actors of the process and of the victims and the reinforcement of the principle of opportunity are undoubtedly some of them. Probation, diversion, compliance, criminal mediation are institutions that stand on the principle of consent for procedural purpose…
INTRODUZIONE AL D.LGS. 19 GENNAIO 2017, N. 3, DI ATTUAZIONE DELLA DIR. 2014/104/UE SUL RISARCIMENTO DEI DANNI PER VIOLAZIONE DELLA NORMATIVA ANTITRUST
2018
Con l’emanazione del d.lgs. 19 gennaio 2017, n. 3 e` stata data attuazione alla direttiva 2014/104/UE del Parlamento e del Consiglio del 26 novembre 2014, relativa a determinate norme che regolano le azioni per il risarcimento del danno ai sensi del diritto nazionale per violazioni delle disposizioni del diritto della concorrenza degli Stati membri e dell’Unione europea. Lo scritto, nell'introdurre una serie di commenti alla neo-introdotta normativa, esamina il percorso evolutivo che ha condotto all'emanazione della direttiva, le scelte con essa operate e le modalità di recepimento nell'ordinamento italiano. With the issuance of Legislative Decree January 19, 2017, no. 3 was implemented the…
Lubāna ledus loba veidotās reljefa formas Atzeles pacēlumā
2022
Grīnbauma, I. 2022. Lubāna ledus loba veidotās reljefa formas Atzeles pacēlumā. Maģistra darbs. Rīga, Latvijas Universitāte, Ģeogrāfijas un Zemes zinātņu fakultāte. Maģistra darbā tika analizētas glaciālās reljefa formas un to izkārtojums Austrumlatvijā, Atzeles pacēlumā, pielietojot 1 m izšķirtspējas digitālo reljefa modeli, kas iegūts no lāzerskenēšanas datiem. Pētījuma teritorija atrodas Fenoskandijas ledus vairoga dienvidaustrumu sektorā, kur uzvirzījās Lubāna ledus lobs. Pētījuma teritorijas glaciālā ģeomorfoloģija nodrošina lielisku iespēju pētīt zemledāja apstākļus un ledus loba plūsmu un iespējamos uzplūdus. Lubāna ledus loba atstātās “pēdas” robežojas no lielizmēra glaciālajiem lin…
Ce:YAG-PMMA nanocomposite for white LED
2012
Ce:YAG-PMMA composite was prepared by a melt compounding method. The characterization was performed using transmission electron microscopy, X-ray diffractometry, and photoluminescence spectroscopy. Results showed that Ce:YAG particles are well dispersed in the polymeric matrix. The luminescence properties of the nanocomposite do not show quenching or significant spectral shift indicating that the nanocomposite can be useful for advanced applications such as white LED construction.
Ce:YAG composites for white LED
2015
Composites and luminescent polymers have been recently found to be potential candidates for the development of white LED, lasers and luminescent concentrators for solar cells. Due to its luminescence properties YAG doped with lanthanides ions is a good candidate as light emitting filler. In a recent our work, the preparation of a polymeric nanocomposite containing Ce:YAG nanoparticles using in situ polymerization has been reported [1]. A good dispersion of Ce:YAG nanoparticles has been obtained maintaining them luminescence properties. In addition, an increase of thermal stability and stiffness of PMMA was observed [2]. Then, the preparation of Ce:YAG-PMMA composite has been performed by us…
Polymeric Ce:YAG nanocomposites: synthesis and characterization
2015
These last years, the development of hybrid polymer-inorganic nanocomposites has been attracted much attention. In particular, composites containing lanthanide-doped materials as filler are candidates for the development of light emitting diodes, lasers and solar cells. Polymers such as polymethylmethacrylate (PMMA), polycarbonate (PC) and polyurethane (PU) are adequate matrices because their good transmission over the visible spectral range, excellent mechanical properties of plasticity, lightness, easiness of fabrication and low cost of mass production. Yttrium aluminum garnet (YAG) doped with Ce(III) ions is one of the yellow phosphor used in the major commercial white LED combined with …
LE AREE INTERNE PER LO SVILUPPO DEL TERRITORIO E LA COMPLEMENTARITÀ DI PROGRAMMI E STRUMENTI FRA LE POLITICHE EUROPEE DI SVILUPPO RURALE E DI COESIONE
Le Aree Interne rappresentano un tema particolarmente importante per la programmazione e la spesa dei fondi comunitari nel periodo 2014-2020 perché costituiscono il più grande esempio di complementarità fra le Politiche europee di sviluppo rurale e di coesione. Per lo sviluppo di queste Aree è stata creata una Strategia Nazionale per le Aree Interne (SNAI) che mira alla valorizzazione ed al recupero di tutti quei territori (rurali, montuosi, svantaggiati) dal carattere marginale rispetto alla disponibilità e all’offerta di servizi essenziali. La peculiarità di tale Strategia è quella di promuovere lo sviluppo di aree che sono uniformemente distribuite in tutto il comprensorio nazionale a di…
