Nova: Reunión de trabajo del proyecto europeo Oceans. RA/VR para alfabetización marina.

El próximo día 20 de junio se reúne en el Cesga el consorcio del proyecto europeo OCEANS ("Ocean Connections: Developing Ocean Literacy through Creative Digital Pedagogies"), coordinado por la Universidad de Exeter (UK), y que cuenta con 8 socios europeos (universidadades, acuarios y escuelas) de Gran Bretaña, Dinamarca y España. Por la parte española / gallega, participa el Acuario Finisterrae (Concello da Coruña), y el CPI O Cruce. El Cesga tiene el papel de socio tecnológico del proyecto.

Este proyecto educativo Erasmus+ tiene el objetivo de explorar las potencialidades de las pedagogías creativas y herramientas de Realidad Virtual y Aumentada en la educación en ciencias, en concreto para reforzar la alfabetización marina.

El Cesga lidera el paquete tecnológico que propondrá y dará soporte a la experimentación con materiales y herramientas de Realidad Virtual y Mixta, teniendo en cuenta el contexto y posibilidades de desarrollo en el marco del proyecto piloto. Durante el mismo, se diseñarán y llevarán a cabo diversas actividades escolares en el aula y los tres acuarios participantes, que se analizarán para analizar el uso y potencialidades de estas pedagogías creativas y herramientas tecnológicas.

Nova: HOW CAN TIO2 BE CONVERTED INTO A NOVEL VISIBLE LIGHT PHOTO-ACTIVE MATERIAL?

Fundamental and applied research comes together via international networking, using the facilities of the CESGA Super-Computer Center (Spain), the Brazilian Synchrotron Light Laboratory (LNLS), and the special synthesis technique of subnanometer-sized metal clusters by the company NANOGAP: de Lara-Castells et al. [1] address the question how a special surface treatment can change the optical properties of TiO2. This compound is a semiconductor material which is known to many as a bright white pigment used in numerous applications ranging from paint over sunscreens and even toothpaste. In skincare products, titanium dioxide is often used due to its ability to adsorb UV light, the high-energy part of the solar spectrum.

Now, these excellent adsorption properties triggered the following thoughts: Can this adsorption be somehow improved even further?. Can one take advantage of this semiconductor to somehow harvest more of the energy the sun provides, and is there a chance to directly steer this energy into chemical reactions?.

Nova: CESGA’s TRAFAIR project was awarded Forum Pa at Rome

The Trafair Project has been awarded at the Pa Forum in Rome today with the "Sustainable PA Award, 100 projects to achieve the objectives of the 2030 Agenda".

The project TRAFAIR - Understanding Traffic Flows to Improve Air Quality (https://www.cesga.es/en/investigacion/proyectos/Proyecto?id=736), co-funded by the European Community and in which CESGA participates, arose from the need of large cities to check air quality quickly and efficiently with a system that allows to take decisions that improve said quality benefiting citizens, businesses and administrations.

The objectives of this project are to provide estimates of air pollution in the city and to develop a prediction service based on the specific meteorology of the area and on the actual traffic flows that move through the city, in addition to publishing said data to the public.

These objectives are what have made TRAFAIR win the "Sustainable PA Award - 100 projects to achieve the objectives of the 2030 Agenda", initiative promoted by FPA in collaboration with ASVIS (Italian Alliance for Sustainable Development) in the event FORUM PA 2019 .

Nova: Big Data Platform upgraded to Hadoop 3

The Big Data platform has been upgraded to Hadoop 3, including also the new Spark 2.4.

The Big Data service allows not only processing in parallel large volumes of information, but also collecting and processing streaming data and using Jupyter Notebooks for exploration and visualization tasks.

The service is based in the last version of Cloudera's Hadoop distribution, CDH6, based on Hadoop 3 which offers a stable solution that included numerous components of the Hadoop ecosystem: YARN, HDFS, MapReduce, Spark, Flume, Hive, Impala, HBase, ...

The upgraded platform is accessible using SSH to **hadoop3.cesga.es**, while the old one based on Hadoop 2 will continue to be accessible through hadoop.cesga.es. To ease the transition, the old platform will remain active until June 30, when it will be shutdown.

In the new User Guide that has been prepared there is a section explaining how to migrate the data from HDFS: http://bigdata.cesga.es/user-guide/migrating_data.html

It is not neccessary to migrate the data in the HOME filesystem since the data in the old platform have been automatically migrated from GlusterFS to the new HOME.

For more information about the platform, including tutorials to quickly learn the different tools, we recommend you to access the following portal that isdevoted to the platform: https://bigdata.cesga.es

This portal included a web interface (WebUI) that allows to perform most common tasks using the browser. We also recommend you to read the new user guide that we have prepared: http://bigdata.cesga.es/user-guide

Nova: VII edición del Día Internacional de las niñas en las TIC

En el CESGA celebramos hoy la séptima edición del «Día Internacional das Rapazas nas TIC». Con nosotr@s estuvieron 4 jóvenes gallegas fantásticas que investigan, trabajan y emprenden con las TIC compartiendo su experiencia y respondiendo a todas las preguntas que formularon los cerca de 400 escolares de 8 centro de toda Galicia. En esta séptima edición lanzamos el concurso  #ApuntasTech?  que aspira a generar un catálogo de propuestas que ayuden a despertar entusiasmo por la tecnología y alienten las vocaciones tecnológicas tempranas. #ApuntasTech? recibió en esta primera edicción 31 propuestas.
