“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

Innaxis presents paper on new approach to safety at the USA and Europe ATM R&D Seminar

Safety is a critical aspect of air traffic management and it receives significant attention from the research community. This criticality leads to lower innovation in different safety aspects, ensuring that only well-known and established procedures and technologies are applied. In this context, new ways to innovate in safety assessment techniques could not only provoke a significant change in the safety levels but also enable technologies and procedures through easier and more straightforward safety analysis.

Innaxis is a firm believer in the potential of complex networks analysis and the power of Data Science techniques. We will present the paper Synchronization Likelihood in Aircraft Trajectories in the next USA/Europe Air Traffic Management R&D Seminar, held from June 10 to 13, 2013 in Chicago. We strongly believe these techniques will set the foundation for new ways of analysing safety levels in different contexts; from providing new techniques and correctly evaluating the safety levels of large airspace blocks to the actual development of predictive analytics that would assist in the implementation of new automation technologies.

Please attend Massimiliano Zanin’s presentation of his paper if you are attending the Seminar and do not hesitate to contact him if this area is of interest to you. Massimiliano is reachable on mz@innaxis.org.


The Federal Aviation Administration and the EUROCONTROL Organization will host the Tenth USA/Europe Seminar on ATM R&D June 10-13, 2013 in Chicago, IL, USA.

Innaxis publishes White Paper on Energy research

On September the 24th we submitted the final version of the ComplexEnergy White Paper to the European Commission. It has been already sent to the participants and interested individuals and is published on the ComplexEnergy website: www.complexenergy.eu.

ComplexEnergy is an initiative led by The Innaxis Foundation and Research Institute and Create-Net with the purpose of bridging the ICT, Energy, and Complex Systems research communities. ComplexEnergy aims to find out challenging and innovative research threads which improve the understanding and modelling of energy systems from a comprehensive perspective, conceiving them as Complex Systems.

The White Paper discusses why the Energy System can be understood as a Complex System and how Complexity Science can contribute in improving its understanding and predictability. The White Paper is the result of a coordinated effort between researchers of the three fields who have contributed interesting ideas and fruitful comments to the document.

Innaxis believes in promoting this innovative idea and looking at challenges from a different perspective. The White Paper is a significant accomplishment for the ComplexEnergy initiative and we hope to continue to move forward in this direction. To read the White Paper please click here, we hope the document will catalyze new ideas and further development on this frontier. All comments and questions are welcomed at: info@innaxis.org.

ComplexEnergy is supported by the Future and Emerging Technologies (FET) programme within the ICT theme of the Seventh Framework Programme.



ComplexEnergy White Paper Draft Now Available

The Innaxis Foundation & Research Institute along with CREATE-NET are pleased to publish a draft of the ComplexEnergy White Paper.

After many revisions and discussions, a first draft of the ComplexEnergy White Paper has become available. Members of the Expert Panel also contributed to the advancement of the White Paper and will continue to do so until the paper becomes finalised.

The White Paper is one of the deliverables for the ComplexEnergy initiative. The project, funded by the European Commission´s 7th Framework Programme, focusses on Complex Systems for an ICT-enabled Energy System. The activities of the project can be described as the following:

  • Bridge the gap between Complex Systems, ICT and Energy research communities.
  • Identify the potential of ICT-enabled energy modelling, control, and management solutions built on the results of Complex Systems Science.
  • Propose future FET initiatives at the junction of ICT, Energy and Complex Systems.
  • Magnification of the level of awareness, at European scale, of the potential impact of advanced ICT techniques implementing concepts and tools from Complex Systems research for the design and governance of the energy system.

The draft version of the White Paper can be found on the ComplexEnergy website here .  The draft is intended to stimulate discussion and comments from the public. Considering that the ComplexEnergy initiative is a crossover between the ICT, Energy, and Complex Systems disciplines, many professionals are sure to find the paper interesting.

Any type of feedback and comments are welcomed and can be sent to: innovation@innaxis.org .

Innaxis publishes two papers, initiates ComplexWorld.eu

External projects, internal projects, publishing papers, submitting proposals- This multi-tasking ability is part of the reason why Innaxis never finds a dull moment.  Even in the downtime that often occurs in European countries during the summer months, Innaxis has published two documents related to Complexity Science.

This multi-tasking achievement was deemed capable through the efforts of Massimiliano Zanin, Lucas Lacasa, and Miguel Cea. They have written ¨Dynamics in Scheduled Networks¨ which has been published in the interdisciplinary journal Chaos (http://chaos.aip.org). Chaos is a quarterly journal published by the American Institute of Physics devoted to increasing the understanding of nonlinear phenomena and describing the manifestations in a manner comprehensible to researchers from a broad spectrum of disciplines.

The paper will be published in the June 2009 edition and is already available online (Chaos-an Interdisciplinary Journal of Nonlinear Science website). The paper explains how time restrictions are usually neglected when studying real or virtual systems through complex network theories, and a static structure is normally defined to characterize which node is connected to another. This approach seems to be oversimplified as real networks are indeed dynamically modified by external mechanisms.  The paper presents a scheduled network formalism that takes into account such dynamical modifications by including generic time restrictions in the structure.  Below is a paragraph taken from the paper explaining how scheduled networks can be used in an air traffic management scenario.


The same team of people along with Samuel Cristobal has also published a contribution titled, ¨A Dynamical Model for the Air Transportation Network¨ which has been submitted and approved for  European Conference on Modelling and Simulation ’09. The publication will be discussed at the June 9-12 event in Madrid Spain under the category ¨Discrete Event Modelling and Simulation in Logistics, Transport and Supply Chains (LT) (http://www.scs-europe.net/conf/ecms2009/index.html).

In this contribution, Scheduled Networks are used as a framework for simulating the growth of virtual aeronautical networks. The basic assumption is that the cost for passengers should be minimized, which is approximated with the time needed to go from one airport to another one. Some results are presented, and the role and importance of hubs (that is, central airports where great part of the flights are concentrated) is discussed. Peer reviewing for both publications was done by F J Mancebo, founder of the Innaxis Foundation & Research Institute and longtime UPM (Universidad Politécnica de Madrid) mathematics professor in the Superior School of Aeronautics.

The papers recently published by the Innaxis group have further advanced the opportunities to expand the findings into different scenarios. Following the same direction, Innaxis will be launching ComplexWorld.eu, an initiative to foster and promote the study of system complexity in the field of air transport. More particularly, ComplexWord.eu will be a candidate network for the SESAR Long Term initiative (WP E). As Air Transport Networks are becoming more complex characterized by an increasing number of airspace users which inevitably brings indeterminacy and unpredictability to the behavior of the system that needs to be carefully studied, analyzed, modeled, simulated and understood. Although still in it´s preliminary phase, ComplexWorld.eu will promote a research plan on how to tackle these issues in the field of air traffic management, introducing the concept of complexity management in the context of the 4D Trajectory Management operational concept developed in SESAR.
