Relation entre les densitées de chaîne et trame et sa influence sur l’aspect superficiel des tissus obtenus avec ligaments de relief
La estabilidad estructural de los tejidos depende del equilibrio entre la densidad, el título del hilo y el ligamento. De la combinación de estos tres elementos depende el grado de tupidez. Asimismo, para una misma tupidez, existen diferentes relaciones entre las densidades de urdimbre y trama, que variaran el aspecto del tejido.The structural stability of fabrics depends on the balance between density, yarn count and weave. From the combination of these three elements comes the tightness of the fabric, and for the same tightness, different combinations of warp and weft density are possible that may, therefore, change the appearance of the fabric.La stabilité structurelle des tissus dépend de l’équilibre entre la densité le titre du fil et l’armure. Pour une même épaisseur, peut y avoir différentes relations entre les comptes de chaîne et de trame, que peuvent varier l’aspect final du tissuPeer Reviewe
Facció de museus com a lleure seriós (serious leisure)
Peer-reviewedAmateur museums are independent museums made as leisure projects outside professional frameworks. This paper attempts to distinguish museum making as a leisure activity from professional museums and from collecting and to broadly identify some implications arising from their relations as questions of interest for future research. To do so, I rely on Stebbins theory of serious leisure (1992) and on some literature on institutionalism, collecting and museology, specially Martin¿s research on popular collecting and its relation to professional museums (1999).Els museus amateurs són museus independents que s¿han creat com a activitat de lleure, al marge de qualsevol entorn professional. Aquest article intenta distingir entre els museus creats com a activitat de lleure, els museus professionals i el col·leccionisme, i alhora identificar àmpliament algunes de les implicacions que sorgeixen de les seves relacions com a qüestions d¿interès per a futures investigacions. Per a fer-ho, m¿he basat en la teoria de Stebbins sobre el lleure seriós (1992) i en certes obres sobre institucionalisme, col·leccionisme i museologia, especialment la recerca de Martin (1999) entorn del col·leccionisme popular i la seva relació amb els museus professionals.Los museos amateurs son museos independientes creados como una actividad de ocio, al margen de cualquier entorno profesional.

Para ello, me he basado en la teoría de Stebbins sobre las actividades de ocio serio (1992) y en algunas obras sobre institucionalismo, coleccionismo y museología, especialmente la investigación de Martin (1999) sobre coleccionismo popular y su relación con los museos profesionales
From Iberians to Romans. The Latinization of Iberian onomastics through Latin epigraphic evidence
This article provides a comprehensive analysis of the survival of Iberian names in Latin inscriptions. The study of how Iberians left behind their traditional names in favour of Latin ones offers new insights into the complex process of the cultural and linguistic transformation of indigenous populations of Hispania
A methodology for continuous usability assessment in educational content portals
La Comisión Europea ha mostrado un gran interés en promover portales con contenido educativo en diversas áreas de conocimiento. Este tipo de proyectos están claramente destinados a que el usuario final pueda emplear el portal de forma útil para su educación. En este sentido, la metodología de trabajo que debería seguirse para este tipo de proyectos debería estar centrada en el usuario, esto es, debería desarrollarse conforme a los principios de lo que es conocido como "User Centered Design". Sin embargo, este no es el caso de los proyectos analizados, donde se han detectado varios problemas comunes relativos a como se realizan las pruebas y experimentos con usuarios. El propósito de este trabajo es desarrollar una metodología de evaluación continua de la usabilidad para portales de contenido educativo, mostrando que esta metodología es aplicable en el contexto de este tipo de proyectos europeos y los posibles beneficios que traería su implantación.The European Commission has shown a great interest in promoting educational content
portals in different areas of knowledge. These projects are clearly intended to allow end users
to use said portals in useful ways for education purposes. In this sense, the methodology that
should be followed for this type of projects should be centered on the user, that is, they should
be developed according to the principles of what is known as "User Centered Design".
However, this is not always the case of the analyzed projects, in which several common
problems related to the way in which they deal with tests and experiments with users have
been detected. The purpose of this work is to develop a methodology for the continuous
assessment of usability for educational content portals, showing that this methodology is
applicable in the context of this kind of European projects, as well as the potential benefits
that its implementation would bring.Grado en Sistemas de Informació
Indigenous naming practices in the Western Mediterranean: the case of Iberian
The Iberian language is directly attested by ca. 2,250 inscriptions spanning the period from the 5th century BC to the 1st century AD, distributed between Eastern Andalusia and Languedoc. Although it must be considered a non-deciphered language, a large number of personal names have been identified in Iberian texts. The document that enabled the understanding of the basic structure of Iberian names is a Latin inscription from Italy (the Ascoli Bronze) recording the grant of Roman citizenship to Iberians who had fought for Rome during the Social War (90-88 BC). The study of this document paved the way for the identification of Iberian names in texts written in local languages, on the one hand, and in Latin and Greek epigraphic and literary sources on the other. This paper provides a state-of-the-art overview of research on Iberian onomastics, by synthesising the main recent achievements along with the remaining lines of research; it also investigates our understanding of the grammatical and syntactic structure of Iberian names, and analyses the evolution of Iberian naming patterns under Roman domination, by taking into account both Iberian and Latin documents
A direct-sequence spread-spectrum super-regenerative receiver
Current applications of the super-regenerative receiver use narrowband modulations. In this paper a new architecture that allows incoherent detection of spread-spectrum signals is presented. A pseudorandom code generator has been added to the original circuit. It is clocked by the quench oscillator and takes advantage of the characteristic broad reception bandwidth. CDMA can be achieved via ASK and FSK modulated signals with high simplicity in the RF stage as well as low power consumption.Peer ReviewedPostprint (published version
