A Configuration of 3-phase Traction Inverter Employing {SiC} Devices
2022
In the scenario of a more and more sustainable society, an increasing electrification in different fields, such as mobility and industrial applications, is foreseen in the next decades. As far as power electronics is concerned, a challenging perspective is represented by achieving higher and higher switching frequencies while maintaining high voltage and low power losses. To do that, emerging semiconductor technologies are supposed to be increasingly employed, as well as innovative topologies of connections among switching devices. Among them, the cascode configuration can notably contribute to achieve high levels of dV/dt without losing efficiency. In this paper, a 3-phase Pulse Width Modu…
Transcodage des nombres chez l'enfant : approche développementale, inter-linguistique et différentielle
2010
Number transcoding in children is a domain rarely investigated. The PhD goal is to test the main predictions allowed by the transcoding model “ADAPT” of Barrouillet et al. (2004) in particular its ADAPTBASIC version concerning transcoding at the beginning of learning. Unlike the other transcoding models (e.g., McCloskey on 1992), ADAPT is a developmental, asemantic and procedural model. In this research the concerned transcoding allows to shift the verbal form of number to Arabic form. This thesis questions the acquisition of transcoding and its development with learning, as well as the impact of the inter-linguistic and individual differences. To reach these objectives, we adopted a develo…
Ultrasound assisted method to increase soluble chemical oxygen demand (SCOD) of sewage sludge for digestion
2004
The aim of this study was to clarify the possibilities to increase the amount of soluble chemical oxygen demand (SCOD) and methane production of sludge using ultrasound technologies with and without oxidising agents. The study was done using multivariate data analyses. The most important factors affected were discovered. Ultrasonically assisted disintegration increased clearly the amount of SCOD of sludge. Also more methane was produced from treated sludge in anaerobic batch assays compared to the sludge with no ultrasonic treatment. Multivariate data analysis showed that ultrasonic power, dry solid content of sludge (DS), sludge temperature and ultrasonic treatment time have the most signi…
Preliminary test on a cascode switch for high-frequency applications
2020
Nowadays, an increasing electrification level is being addressed towards different sectors, such as transportation and industrial electronics. To bear that, high speed electrical machines represent a mature technology in different application fields, e.g. avionics, automotive, compressors and spindles. In order to guarantee high speed while keeping high power quality without adopting bulky filtering circuits, DC-AC converters shall be controlled by means of high Pulse Width Modulation (PWM) frequencies. In addition to the emerging switching device technologies, such as those based on Silicon-Carbide (SiC) and Gallium-Nitride (GaN), alternative circuital topologies are crucial in order to co…
Un nouveau modèle de transcodage des nombres : aspects développementaux, neuropsychologiques et computationnels
2005
Ce texte est un rapport de fin de recherche issu de l'ACI cognitique.; L'objectif du projet était de produire et valider empiriquement un modèle développemental de transcodage des nombres de leur forme verbale (orale ou écrite) vers leur forme en chiffres. Le modèle, baptisé ADAPT (A Developmental Asemantic Procedural Transcoding model), est un système de production qui transforme un input verbal en chaîne de chiffres par la mise en œuvre de procédures. Celles-ci lisent le contenu de la mémoire de travail et le transforment en récupérant en mémoire à long terme des associations entre formes verbales et formes en chiffres. L'originalité du modèle est sa capacité à apprendre à partir de son f…
Aproximaciones en la preparación de contenido de vídeo para la transmisión de vídeo bajo demanda (VOD) con DASH
2023
El consumo de contenido multimedia a través de Internet, especialmente el vídeo, está experimentado un crecimiento constante, convirtiéndose en una actividad cotidiana entre individuos de todo el mundo. En este contexto, en los últimos años se han desarrollado numerosos estudios enfocados en la preparación, distribución y transmisión de contenido multimedia, especialmente en el ámbito del vídeo bajo demanda (VoD). Esta tesis propone diferentes contribuciones en el campo de la codificación de vídeo para VoD que será transmitido usando el estándar Dynamic Adaptive Streaming over HTTP (DASH). El objetivo es encontrar un equilibrio entre el uso eficiente de recursos computacionales y la garantí…
Ancora sulle stele e le edicole dipinte di Lilibeo: immagini, formule, funzioni
2020
Il contributo esamina le stele e i naiskoi funerari dipinti di Lilibeo (Sicilia), recentemente incrementati da due nuove acquisizioni. Sono presi in considerazione i (pochi) dati contestuali, oltre a tipologia, iconografia e formule epigrafiche, allo scopo di mettere in luce specificità, funzioni e messaggi di tali manufatti. Alcuni elementi “trasversali” di carattere antiquario e stilistico, oltre ai dati epigrafici, attestano una sostanziale contemporaneità delle stele più semplici con singolo personaggio stante, con melograno in mano, e dei più elaborati naiskoi con “Totenmahlmotiv”, nella tarda età repubblicana. Le chiare differenze di morfologia, iconografia, formule epigrafiche e luog…
Thinking Narratively. Between Novel-Essay and Narrative Essay
2022
What is the connection between philosophical enquiries and storytelling in contemporary narrative? Is it possible to outline some features of a so-called philosophical fiction in Western literature throughout the last two centuries? This book aims to provide a plural answer, hosting extensive essays by seven young researchers coming from different fields (Theory of literature, German, American, Russian and Italian contemporary literature, history and evolution of the essayistic form). A short The volume is addressed to all those with a strong interest in both evolution of philosophical speech and history of the novel and has a strong vocation to promote interdisciplinarity in literary studi…
