Presentation

We are happy to welcome you to the second edition of the UCA COMPLEX DAYS, held on Monday, 25 March 2019 at the Saint-Paul Hotel, NiceOrganized for a second time by the Academy of Complex Systems, this meeting aims at bringing together people who are working on Complex Systems. It fosters exchanges between researchers (students, post-docs and senior scientist) from different scientific areas and will be the best place to discuss and share our work within the academic community. 


During this day, 4 plenary scientific presentations, showing 4 different visions of complex systems across 4 different disciplines will be given by invited keynote speakers from the broad field of complex systems.  They will be intersected by poster session, in plenary: flash presentations of posters for no more than 5 minutes.

 

Three prizes will be awarded at the end of the day!

Two will be offered to doctoral students to reward the best flash talk and the best poster and the third prize will be offered to a post-doctoral candidate for the best flash talk. The Award: payment of travel expenses for the successful doctoral student and/or post-doctoral fellow to participate at an international conference (up to a maximum of €2000/person), with the obligation to mention the UCA funding support. Please note that an equivalence of 4 hours of transversal doctoral training or 1/3 ECTS will be provided to doctoral students (EDSFA/STIC) who have attended the Complex Days meeting.


To present your poster during this day, send us an abstract of the topic you are working on before Friday, 8 February 2019

The abstract can be on any topic within the scope of the Academy of Complex Systems and must be written in English and intelligible. The keyword for this day is transdisciplinarity, notably through accessible presentations, adapted for a broad, heterogeneous audience.

The Academy possesses a remarkably broad spectrum of scientific activities involving complex systems from mathematical to societal models, including complex environment physics, extreme phenomena, networks in the broad sense of the term, systems biology and chemical interactions. Creating and reinforcing links between teams from different domains ; combining existing skills in UCAJEDI in modeling and simulation of complex systems in order to place them effectively in the service of current significant societal issues and encouraging the identification of common methodological approaches and the emergence of shared study objects in transversal research topics are the main goals of the Academy of Complex Systems.
