Modelos numéricos para la simulación y el análisis de señales atmosféricas

2015

Los rayos son la principal fuente de radiación de origen natural en la atmósfera terrestre, dado que cada segundo, del orden de un centenar de ellos descargan sobre la superficie de la Tierra, siendo el fenómeno más frecuente en unas regiones que en otras. Dichas descargas emiten la mayor parte de dicha radiación en las bandas ELF y VLF, bandas en la cuales las señales presentan una baja atenuación. La radiación emitida da lugar, en la banda ELF a las resonancias de Schumann y en la banda VLF a campos resonantes en la guía formada por la ionosfera y la superficie de la Tierra. Estas señales nos permiten inferir, por una parte, las propiedades de la ionosfera, y por otra la ubicación donde s…

Color constancy in dermatoscopy with smartphone

2017

The recent spread of cheap dermatoscopes for smartphones can empower patients to acquire images of skin lesions on their own and send them to dermatologists. Since images are acquired by different smartphone cameras under unique illumination conditions, the variability in colors is expected. Therefore, the mobile dermatoscopic systems should be calibrated in order to ensure the color constancy in skin images. In this study, we have tested a dermatoscope DermLite DL1 basic, attached to Samsung Galaxy S4 smartphone. Under the controlled conditions, jpeg images of standard color patches were acquired and a model between an unknown device-dependent RGB and a device independent Lab color space h…

Primavera del periodismo en Venezuela: cooperación y democracia. Aproximación desde la ética de la razón cordial

2020

El objetivo general de este texto es analizar cómo la noción de la cooperación puede entronizarse en el oficio del periodismo desde la perspectiva de la ética de la razón cordial. Se pondrán en relación dos ejemplos de periodismo colaborativo en Venezuela,que aun no teniendo como base teórica ética, se rigen por ellos. Con este artículo se aspira a generar espacios de reflexión para fortificar el êthos de la comunicación social, de las empresas informativas y del periodista, con el norte de la democracia yla justicia social. Los autores principales de esta investigación son: Patrici Calvo (2012, 2017, 2018), para hablar de la cooperación desde la ética de la razón cordial, corriente filosóf…

Fixed Points for Multivalued Convex Contractions on Nadler Sense Types in a Geodesic Metric Space

2019

In 1969, based on the concept of the Hausdorff metric, Nadler Jr. introduced the notion of multivalued contractions. He demonstrated that, in a complete metric space, a multivalued contraction possesses a fixed point. Later on, Nadler&rsquo

Le prix des paysages périurbains

2007

L'évaluation économique du prix des paysages périurbains utilise des analyses géographiques (occupation des sols, composition paysagère, distance à des biens paysagers, paysages vus : champ de vision, objets, formes). L'article fait le point sur la littérature en matière de méthode et de résultats et présente l'estimation du prix d'attributs paysagers dans la ceinture périurbaine de Dijon.

Large numbers of cold positronium atoms created in laser-selected Rydberg states using resonant charge exchange

2016

Lasers are used to control the production of highly excited positronium atoms (Ps*). The laser light excites Cs atoms to Rydberg states that have a large cross section for resonant charge-exchange collisions with cold trapped positrons. For each trial with 30 million trapped positrons, more than 700 000 of the created Ps* have trajectories near the axis of the apparatus, and are detected using Stark ionization. This number of Ps* is 500 times higher than realized in an earlier proof-of-principle demonstration (2004 Phys. Lett. B 597 257). A second charge exchange of these near-axis Ps* with trapped antiprotons could be used to produce cold antihydrogen, and this antihydrogen production is e…

Le valenze della Danza Movimento Terapia in presenza e a distanza. Corpo e relazioni durante la pandemia del COVID-19

2022

Elena Mignosi e Fernando Battista approfondiscono nella loro articolo le specificità della Danza Movimento Terapia (DMT) e i suoi numerosi ambiti applicativi (educativo, formativo clinico, terapeutico, sociale/inclusivo , riabilitativo). Conducono quindi una riflessione sulle modalità in presenza e da remoto, individuando quale efficacia possa avere partecipare ad un esperienza artisctico-creativa e corporea attraverso uno schermo. La pandemia da Covid 19 ha infatti reso necessario ripensare quelli che erano ritenuti i punti cardine del setting di DMT e di individuare nuove forme di interazione. Infine essi presentano brevemente i capitoli della rivista che costituiscono gli Atti del Conveg…
