Research Projects

EMPOWER

Design and Evaluation of Technological Support Tools to Empower Stakeholders in Digital Education

Given technological developments in other domains and lessons from the pandemic, there is a strong push to invest in technologyaugmented education. However, much remains unknown; for example, what technological abilities are useful in education, how they can be deployed, what training needs arise, and what shape future policies governing this should take.

EMPOWER contributes to resolving these questions by developing novel technological support for the education of children with neurodevelopmental disorders (NDDs).

This use case is, in many ways challenging, and thus ideally suited to 1) make a positive impact on the educational needs of these children, and 2) highlight the potential and limitations of technology-augmented education in a way that can inform future developments generally. NDDs affect approximately 15% of children aged 3 to 17 years.

CERES

Software module to classify asteroids from astronomical images using machine learning.

Near Earth Objects (NEOs) and especially Near Earth Asteroids (NEAs) are potential threats based on their proximity to Earth. For this reason, we need to constantly survey the nearby space around Earth and to continuously monitor NEOs and NEAs to prevent future impacts with our planet. Great research efforts are being done to discover new NEOs and NEAs and their results are highly important both for astronomy education and public outreach.
In this context, the CERES software module is capable of classifying detections in astronomical images and is focused on detecting/identifying asteroids. To accomplish this, we are using machine learning techniques to build up an asteroid classification model. The objectives of the CERES project are focused on:

  • building up a dataset of asteroid images
  • training an asteroid detection classification model
  • developing a software module used to classify detections (of asteroids)

The obtained results highlighted the potential of machine learning techniques in the field of asteroid detection.

HORUS

Software Toolbox for Pedological Monitoring of Transylvanian Area based on Sentinel-2 Data

The main objective of the HORUS Toolbox project concerns with using of Earth Observation data, especially data provided by Sentinel-2, in a very practical and efficient manner, to carrying out pedology studies and producing pedology maps, in the particular context of Transylvanian area. Currently the main soil data sources in the area are represented by field studies, sample analysis and in-situ offline sensors, covering only a small region from the Transylvanian area that we are experimenting. Although oriented on Transylvanian area as the main area of interest, functionalities implemented in HORUS Toolbox will be easily adapted for pedological studies in other regions, mainly based on Copernicus products, but also enabling the integration of other data sources that might be available.

enviroGRIDS

Black Sea Catchment Observation and Assessment System supporting Sustainable Development

enviroGRIDS aims at developing a Black Sea Catchment Observation System that will store, analyze, visualize and disseminate information on past, present and future states of the region to assess and predict its sustainability and vulnerability. A gap analysis will identify specific areas where most efforts are needed. As climatic and hydrological changes are of concern, their impacts on several societal benefits areas of the Group on Earth Observation will be evaluated, namely on environment and health, energy, water, ecosystems, agriculture, biodiversity and environmental risks. EnviroGRIDS will rely on ultra-modern technology using the largest gridded computing infrastructure in the world. It will serve as a benchmark for the development of the European directive on Infrastructure for Spatial Information and for the Global Earth Observation System of Systems.
