“Summerizing” the science

In the last few months, we have been busy at presenting the results of our research work at different conferences. For those of you that could not attend, here you have a short review!

First, several people from Innaxis attended the ECTL / FAA ATM Seminar 2015, in Lisbon, Portugal.

Seddik Belkoura presented a computational framework that compares flight trajectories (planned and executed) to detect all delay-generating events, and that can be used as a tool to identify the causes of non ATFM delay across any en-route system with the appropriate data. This algorithm extracts the probability distribution of the magnitude of a delay caused by one event per flight. From this, it has been possible to show the independence between the amplitude of en-route delay generated by a single event and the global delay of a flight. Additionally, a temporal and spatial assessment of the resilience of the en-route system to delay generation have been provided, which might lead to the identification of spatial zones that generates more delay, hence more fuel consumption, and to new tactical trajectory planification based on each ANS efficiency regarding en-delay recovery.

Additionally, Massimiliano Zanin gave a talk synthesising the results obtained in the POEM project, which we finished one year ago, and that was selected as one of the SESAR “Oustanding Projects” in 2014. We also had new results not presented until now. The focus of the talk was on the potential benefits of using a complex network approach to model the process of delay propagation. By using simple theoretical models, like a percolation process, it is possible to simulate different strategies for limiting delay propagation: all of this without extremely costly simulations, but just using known analytical results of network theory!

Both papers, Seddik’s and MZ’ ones, can be downloaded from the website of the conference.

The week after the ATM Seminar, MZ traveled to New York city, presenting the latest developments of the SecureDataCloud project at the IEEE SERVICES ’15. Impressive conference, with hundreds of attendees, and keynote talks from people of the level of Tsengdar J. Lee (NASA), Eric Brewer (Google) and Guruduth Banavar (IBM Research). In this case, the presentation had a much more applied flavour: describing the development of the software libraries for performing the secure computation, as required by the project and by the specifications suggested by the advising stakeholders. The development of the full system will be described in a paper, now under consideration, that we trust will be published shortly – so, stay tuned!

This is just a short abstract of the topics covered. So, if you need to know more, please contact the authors – mz@innaxis.org and sb@innaxis.org
