La Valoració del dany corporal a l'assegurança de l'automòbil: aplicacions i perspectives de futur

Atès que els accidents de trànsit són una de les principals causes de mortalitat entre la població catalana i l'europea, la recerca en l'àmbit de la valoració del dany corporal és fonamental per a les companyies asseguradores d'automòbils. És per això que l'autor centra l'obra en els dos principals problemes que es generen en les companyies asseguradores: el càlcul de reserves i la negociació de les quanties.Given that traffic accidents are one of the main causes of mortality among the Catalan and European population, current research on physical injury is fundamental for insurance companies. This is why the author discusses the two main problems arising for insurance companies: calculating reserves and negotiating sums

Although computer supported collaborative learning has been widely adopted in many educational institutions over the last decade, there exist still drawbacks which limit their potential in collaborative learning activities. Among these limitations, we investigate information security requirements in on-line assessment, (e-assessment), which can be developed in collaborative learning contexts. Despite information security enhancements have been developed in recent years, to the best of our knowledge, integrated and holistic security models have not been completely carried out yet. Even when security advanced methodologies and technologies are deployed in Learning Management Systems, too many types of vulnerabilities still remain opened and unsolved. Therefore, new models such as trustworthiness approaches can overcome these lacks and support e-assessment requirements for e-Learning. To this end, a trustworthiness model is designed in order to conduct the guidelines of a holistic security model for on-line collaborative learning through effective trustworthiness approaches. In addition, since users' trustworthiness analysis involves large amounts of ill-structured data, a parallel processing paradigm is proposed to build relevant information modeling trustworthiness levels for e-Learning.Peer ReviewedPostprint (author's final draft

Universal Indexes for Highly Repetitive Document Collections

Indexing highly repetitive collections has become a relevant problem with the emergence of large repositories of versioned documents, among other applications. These collections may reach huge sizes, but are formed mostly of documents that are near-copies of others. Traditional techniques for indexing these collections fail to properly exploit their regularities in order to reduce space. We introduce new techniques for compressing inverted indexes that exploit this near-copy regularity. They are based on run-length, Lempel-Ziv, or grammar compression of the differential inverted lists, instead of the usual practice of gap-encoding them. We show that, in this highly repetitive setting, our compression methods significantly reduce the space obtained with classical techniques, at the price of moderate slowdowns. Moreover, our best methods are universal, that is, they do not need to know the versioning structure of the collection, nor that a clear versioning structure even exists. We also introduce compressed self-indexes in the comparison. These are designed for general strings (not only natural language texts) and represent the text collection plus the index structure (not an inverted index) in integrated form. We show that these techniques can compress much further, using a small fraction of the space required by our new inverted indexes. Yet, they are orders of magnitude slower.Comment: This research has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sk{\l}odowska-Curie Actions H2020-MSCA-RISE-2015 BIRDS GA No. 69094

RDF-TR: Exploiting structural redundancies to boost RDF compression

The number and volume of semantic data have grown impressively over the last decade, promoting compression as an essential tool for RDF preservation, sharing and management. In contrast to universal compressors, RDF compression techniques are able to detect and exploit specific forms of redundancy in RDF data. Thus, state-of-the-art RDF compressors excel at exploiting syntactic and semantic redundancies, i.e., repetitions in the serialization format and information that can be inferred implicitly. However, little attention has been paid to the existence of structural patterns within the RDF dataset; i.e. structural redundancy. In this paper, we analyze structural regularities in real-world datasets, and show three schema-based sources of redundancies that underpin the schema-relaxed nature of RDF. Then, we propose RDF-Tr (RDF Triples Reorganizer), a preprocessing technique that discovers and removes this kind of redundancy before the RDF dataset is effectively compressed. In particular, RDF-Tr groups subjects that are described by the same predicates, and locally re-codes the objects related to these predicates. Finally, we integrate RDF-Tr with two RDF compressors, HDT and k2-triples. Our experiments show that using RDF-Tr with these compressors improves by up to 2.3 times their original effectiveness, outperforming the most prominent state-of-the-art techniques

Interacciones entre fármacos de libre venta y de prescripción.

Tesis (Químico Farmacéutico)Los medicamentos son una de las herramientas terapéuticas más utilizadas en la práctica de la medicina, cuyo uso de manera apropiada permite la obtención de importantes beneficios sanitarios representados por la prevención, diagnóstico, curación, atenuación y tratamiento de las enfermedades y sus síntomas. No obstante, su utilización puede llevar a problemas importantes de morbilidad y de mortalidad. Las reacciones adversas son el resultado de una interacción entre el organismo el medicamento y una serie de factores extrínsecos adicionales. Influyen, por tanto, los factores propios, los ambientales, los ligados al propio enfermo (procesos farmacocinéticos, edad, estado patológico) y las asociaciones entre medicamentos. Estas últimas pueden dar lugar a i'11teracciones farmacológicas. Las cuales son necesarias conocer, para predecir las probables interacciones y así advertir a la población y a los profesionales del área de la salud, sobre los potenciales riesgos. Dado que no existen estudios en farmacia comunitaria sobre las interacciones farmacológicas potenciales. Se realizó un estudio observacional, transversal y descriptivo, mediante una encuesta aplicada a 731 clientes-pacientes que frecuentaban los locales de Farmacias Ahumada, de la Provincia de Santiago, con el objetivo de estudiar las posibles interacciones que pudiesen presentarse en la administración conjunta de fármacos de prescripción y de libre venta. De las encuestas realizadas se obtuvo que: el 76,34% de los clientes-pacientes se administra 3 o 4 medicamentos concomitantemente; el consumo promedio fue de 3,92 medicamentos; del total de fármacos el 59,97% corresponde a analgésicos, cardiovasculares y antiinfecciosos; las interacciones de severidad mayor corresponden a fármacos analgésicos + sistema nervioso central; las interacciones más frecuentes corresponden a fármacos analgésicos + cardiovasculares..
