Hydro-mechanical behaviour of a sandy silt from a river embankment
2020
The paper presents the results of an experimental campaign aimed at characterizing the hydro-mechanical behaviour of a sandy silt from a river embankment. Due to continuous river level fluctuations and changing climatic and environmental conditions, flood embankment materials experience frequent variations in degree of saturation and suction values. Such variations strongly impact the earthwork performance both in terms of seepage and stability conditions. For these reasons, a detailed characterization of the material behaviour in unsaturated conditions was carried out. Experiments were designed in order to highlight the response of the involved soil in terms of changes in matric suction an…
Evaluating Safety Systems for Machine Tools with Computer Numerical Control using Analytic Hierarchy Process
2019
Computer numerical control (CNC) machine tools are complex production systems with fully automatic machine parts. Nowadays, high feed rates and machining speeds are used during the machining process. Human operators are still needed to set-up the machine, load/unload workpieces and parts, load the machining code, and supervise the machining process. The operators work in an environment where automated high-speed motions occur, and consequently, CNC machine tools have to be equipped with safety systems. The approach presented in this paper was to evaluate the main safety systems of CNC machine tools based upon the analytic hierarchy process (AHP). The analyzed systems were divided into six m…
Colegialidad docente: un estudio comparativo (España/México) de validación de constructo para el diseño de un instrumento de evaluación
2014
En Bakieva (2011) y Bakieva, Jornet y Carmona (2012) se aportan las bases teóricas y una primera validación de constructo realizada en España para el desarrollo de un instrumento de evaluación de colegialidad docente en Educación Primaria y Secundaria. Aquí presentamos un segundo análisis comparativo de los juicios de dos grupos de profesorado de España y México, que han valorado las dimensiones que componen la Colegialidad Docente. Finalmente, identificamos tres dimensiones de Colegialidad Docente: Satisfacción Laboral, como percepción de lo que “recibe” el sujeto en esa institución, Clima Institucional, como percepción exterior de lo que se vive en la institucional, y Compromiso Instituci…
A Educação para a Cidadania Mundial como aposta de construção de um novo paradigma educativo
2018
Resumo : O objetivo com este estudo e refletir sobre a Cidadania Mundial, por meio de uma investigacao sobre o tema, considerando a evidencia da sua permanencia como prioridade na agenda educativa mundial, tanto para os paises desenvolvidos, quanto para os em desenvolvimento. A Educacao para a Cidadania Mundial tem cobrado ao longo dos ultimos anos um claro protagonismo na reflexao e nas praticas educativas, tanto das organizacoes nao governamentais quanto dos docentes mais comprometidos com um pensar e uma pratica pedagogica alternativa nas suas aulas. Sua inclusao preeminente na agenda global como raiz de sua definicao prioritaria para o marco da Global Education First Initiative (GEFI), …
Emerging Constructions in the L2 Italian Spoken by Low Literate Migrants
2019
The emergence of autonomous interlanguage constructions is widely recognised in the literature on L2 Italian. These constructions involve the overgeneralisation of functional forms learners are in the process of acquiring, e.g., siamo in siamo mangiare &lsquo
Gestió universitària i estils discursius
2008
This article presents some of the results from a broader research study of management styles within the Catalan university world. Two management styles are defined (the collegial and the managerial) and a relationship is established between some of the characteristics of these styles, some discursive features and the gender of the managers. Specifically, an analysis is made of the linguistic markers pertaining to the deictic modality in the discourse that constructs the identity of the analysed individuals. The markers of the deictic modality also make it possible to identity certain characteristic traits of men and women. Methodologically speaking, it could be said that the analysis of the…
Construcciones suspendidas y gestión del turno conversacional en la evaluación de la afasia
2008
Les suspensions de constructions syntaxiques préalablement initiées sont des phénomènes très fréquents dans la conversation quotidienne. On les associe fréquemment à la négociation du changement de tour de parole. Cette dernière situation peut être décrite comme une transformation particulière à travers laquelle un déficit littéral dans l’expression est réévalué par les interlocuteurs en tant que moyen symbolique pour l’exercice de déterminées fonctions pragmatiques ou pour l’expression de certains signifiés. Nous explorons ici les différents contextes dans lesquels se manifestent ces fonctions et ces signifiés, tout en tenant en compte des interactions conversationnelles …
Encuentros restaurativos, tránsito de la guerra a la paz: ¿instrumento paliativo o reconstructivo?
2018
El terror, la violencia y la desolación causados por el terrorismo han encontrado una respuesta represiva por parte del Estado. Una respuesta que ha supuesto, por un lado, la quiebra de los valores democráticos de un sistema de derechos -se ha respondido a la violencia con violencia- y por otro, más y más derecho penal. Sin embargo, ni la una ni la otra han servido para acabar con el terrorismo ni para re-construir a las víctimas. La aparición de una mirada restaurativa, de la mediación y los encuentros restaurativos, testados en algunos proyectos, permite albergar esperanza en la justicia, una justicia integradora que busca la reconstrucción social y personal, un tránsito de la guerra a la…
High Performance 3D PET Reconstruction Using Spherical Basis Functions on a Polar Grid
2011
Statistical iterative methods are a widely used method of image reconstruction in emission tomography. Traditionally, the image space is modelled as a combination of cubic voxels as a matter of simplicity. After reconstruction, images are routinely filtered to reduce statistical noise at the cost of spatial resolution degradation. An alternative to produce lower noise during reconstruction is to model the image space with spherical basis functions. These basis functions overlap in space producing a significantly large number of non-zero elements in the system response matrix (SRM) to store, which additionally leads to long reconstruction times. These two problems are partly overcome by expl…
The factorization method for electrical impedance tomography data from a new planar device.
2006
We present numerical results for two reconstruction methods for a new planar electrical impedance tomography device. This prototype allows noninvasive medical imaging techniques if only one side of a patient is accessible for electric measurements. The two reconstruction methods have different properties: one is a linearization-type method that allows quantitative reconstructions; the other one, that is, the factorization method, is a qualitative one, and is designed to detect anomalies within the body.
