5. Research and development
StroNGER starts as an academic spin off and the Research and Development has an
important role. Stronger is active in collaborations as a SME partner in joint
research proposals.
A presentation that describes StroNGER and its expertise for Horizon 2020 calls is
downloadable at http://www.slideshare.net/StroNGER2012
The main topics are:
• Resilience assessment – Multihazard approach. StroNGER is developing methods
and quantitative indices for the assesment of the resilience of urban areas, also in
case of multiple actions as fire after an earthquake.
• Sustainability and Energy Harvesting. StroNGER is working on methodologies and
tools for harvesting energy from the vibrations of civil structures and
infrastructures.
