Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.

2020

As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…

Proportions. Science, Musique, Peinture et Architecture

2012

Le langage des proportions est un langage de comparaison. Outil scientifique, il met en relation grandeurs mathématiques ou physiques (deux cercles, deux mouvements, deux sons, etc.). Pour autant, son application ne se restreint pas au seul champ des mathématiques. Erigé en principe philosophique par le principe de comparaison qui le sous-tend, il déploie tout son potentiel analogique en devenant langage constructeur d'harmonie. La théorie des proportions s'ouvre ainsi sur un vaste champ de relations qui définissent canons et règles de beauté dans les diverses disciplines artistiques. S'intéresser aux proportions signifie donc s'intéresser à tous les domaines du savoir. Mais comment aborder…

La transición de Educación Primaria a Educación Secundaria Obligatoria: sentido y significado del uso de recursos y espacios digitales

2019

espanolEl cambio de la Educacion Primaria a la Educacion Secundaria Obligatoria supone el trasvase de informacion y la colaboracion entre centros para realizar acciones conjuntas que faciliten el proceso de transicion y aprovechen el potencial de aprendizaje que ofrece el cambio. Las Tecnologias de la Informacion y la Comunicacion tienen un papel destacado en este proceso de cambio, ya que suponen un medio que facilita la comunicacion e intervencion entre centros, entre familias y entre estudiantes. El proposito fundamental es analizar el grado en que estas son consideradas como beneficiosas en el proceso de gestion del transito de la Primaria a la Secundaria respecto a las tareas de trasva…

Can we automate expert-based journal rankings? Analysis of the Finnish publication indicator

2020

The publication indicator of the Finnish research funding system is based on a manual ranking of scholarly publication channels. These ranks, which represent the evaluated quality of the channels, are continuously kept up to date and thoroughly reevaluated every four years by groups of nominated scholars belonging to different disciplinary panels. This expert-based decision-making process is informed by available citation-based metrics and other relevant metadata characterizing the publication channels. The purpose of this paper is to introduce various approaches that can explain the basis and evolution of the quality of publication channels, i.e., ranks. This is important for the academic …

A Time-Non-Homogeneous Double-Ended Queue with Failures and Repairs and Its Continuous Approximation

2018

We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs. The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure. Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function. We analyze the transient and the asymptotic behavior of the queueing system. Moreover, we derive a heavy-traffic approximation that allows approximating the state of the systems by a time-non-homogeneous Wiener process subject to jumps to a spurious state (due to catastrophes) and random returns to the zero state (due to repairs). Special attention is devoted to the cas…

TimeSens - un logiciel Web pour l'acquisition et le traitement des données sensorielles

2010

TimeSens est un nouveau logiciel dédié à l'acquisition et au traitement des données d'analyse sensorielle. TimeSens bénéficie de l'expérience et de l'expertise de ChemoSens, la plate-forme d'analyse sensorielle du CSGA. TimeSenspropose la plupart des protocoles standards de l'analyse sensorielle (profil, tests hédoniques, DTS), ainsi que des protocoles originaux (MATI, PSP). Les résultats collectés peuvent être analysés à l'aide de méthodes statistiques traditionnelles ou innovantes.
