A Line Impedance Calculator Based on a G3 PLC Modem Platform
2022
Power line communication (PLC) is one of the most today used technologies for both automatic meter reading and many other smart grid applications. In this framework, a characterization of the electrical network in the PLC frequency range is needed in terms of impedance measurement and received signal level. This can allow choosing the most suitable and less noisy frequency ranges for PLC transmission. Usually, these characterization measurements are performed with dedicated instrumentation and in the absence of mains voltage. This article wants to propose an alternative solution, which allows these kinds of measurements to be performed using electronic boards currently used as on-field appl…
Uncertainty evaluation in load flow analysis: real MV distribution networks case studies
2018
This work investigates the measurement uncertainty impact on load flow analysis in medium voltage (MV) distribution networks. The considered algorithm is a simplified load flow algorithm (LFA), developed by authors, which is based on the load power measurements at each secondary substation and one voltage measurement at the slack bus (i.e. the voltage at the MV bus bars of the primary substation). In the viewpoint of a real implementation, to reduce monitoring system costs, the LFA makes use of low voltage (LV) load power measurements for all the substations except those of MV users, where MV transducers are usually already installed. The uncertainties on LFA input quantities (load powers a…

International audience; La preuve de la filiation maternelle, résumée par l’un des adages les plus connus en droit de la famille, Mater semper certa est, a pendant longtemps semblé être une évidence voulue par la nature, donc ne posant que peu de problème juridique, à l’inverse de la paternité. Pourtant, l’évidence a-t-elle toujours été aussi flagrante ? Pourquoi ressentir le besoin de forger un adage ? Quelle fut sa valeur et a-t-il toujours parfaitement reflété la réalité ? Force est de constater que si la maternité est certaine, la preuve de celle-ci se heurte à plusieurs difficultés tant matérielles que processuelles. Il s’agit donc ici de s’interroger sur la place accordée en droit à l…
Connectivity Analysis in EEG Data: A Tutorial Review of the State of the Art and Emerging Trends
2023
Understanding how different areas of the human brain communicate with each other is a crucial issue in neuroscience. The concepts of structural, functional and effective connectivity have been widely exploited to describe the human connectome, consisting of brain networks, their structural connections and functional interactions. Despite high-spatial-resolution imaging techniques such as functional magnetic resonance imaging (fMRI) being widely used to map this complex network of multiple interactions, electroencephalographic (EEG) recordings claim high temporal resolution and are thus perfectly suitable to describe either spatially distributed and temporally dynamic patterns of neural acti…
Menzione di Dio e presenza del cuore nella preghiera islamica e cristiano ortodossa
2020
Il presente studio esamina l'organo del cuore come sede della preghiera cristiana islamica e ortodossa. Nella tradizione islamica la preghiera chiamata dhikr, in quella cristiana ortodossa la preghiera del cuore o esicasta. L'articolo presenta anche strumenti cultuali come la masbaha e il kombuschini, vengono citati anche vari autori islamici e cristiani che hanno fornito riflessioni sull'argomento. The present study examines the organ of the heart as the seat of Islamic and Orthodox Christian prayer. In the Islamic tradition the prayer called dhikr, in the Orthodox Christian one the prayer of the heart or Hesychast. The article also presents cultic tools such as the masbaha and the kombusc…

Los premios literarios y el canon literario. El caso Protagonista Jove
2021
El objetivo del estudio que presentamos en este capítulo1 es actualizar una de las líneas del trabajo realizado por la doctora Blanca Ana Roig Rechou (2013): los premios literarios en la literatura infantil y juvenil. Ahora, apor tamos los datos del Premi de Literatura «Protagonista Jove» que convoca el Consell Català del Llibre Infantil i Juvenil (ClijCAT) desde el curso 1996- 1997, dirigido a lectores de 12 a 16 años. Concretamente, presentamos los datos resultantes del análisis cuantitativo de las 23 ediciones del premio que tuvieron lugar entre 1996 y 2019. PID2019-10587RB-I00
I Symposium of Elite Performance in Combat Sports
2017
This report presents a summary of the I Symposium of Elite Performance in Combat Sports held in Madrid, May 27, 2017. The symposium, organized by the Faculty of Sport Sciences-INEF of the Polytechnic University of Madrid, aimed to bring science closer to practice. A panel of highly successful athletes involved in karate, fencing, and taekwondo shared their experiences. The speakers presented crucial topics for an optimal preparation and high level performance such as strength training, sport psychology, brain maturation, sports nutrition, competition planning, sport injuries, and perceptual-decision making training.
Variazione della pressione sistolica e diastolica con la respirazione
2016
L’attività di ricerca in corso riguarda la possibilità di ricavare dati clinicamente significativi dai segnali ottici PPG (PhotoPletysmoGraphy). Il segnale PPG viene utilizzato per ricavare informazioni sul volume e sulla saturazione del sangue che interessa il distretto illuminato dalla luce IR (infrarosso) usata per l’analisi. Il volume di sangue contenuto nel segmento di arteria esaminato dipende dalla pressione e dal ciclo cardiaco, attraverso la rigidità dell’arteria.
