Newsletter #18

Words From The Editor

Dear Colleague,

Shortly after the last newsletter, here is a new one with some interesting events announcements from our partners and updates on the scientific publications we cover.

A preview of the two new issues of the Combustion and Explosion is presented, together with a few thoughts on the recent release concerning the topic of OpenAccess for scientific papers.

The usual brief review and characterization of interesting papers published since last newsletter is present, as well as an example of some interesting patent applications in the field of ibeacons, specialized positioning devices that could in the future be used in civil aerotransports and space applications.

6th EASN International Conference on Innovation in European Aeronautics Research

We wish to introduce our readers to the 6th EASN International Conference on Innovation in European Aeronautics Research.

This conference, whose website is reachable at the address, will take place October 18 – 21 2016 at Porto, Portugal.

The 2016 EASN Conference will be a flagship event in dissemination of aeronautics research activities and its goal is to share high quality, current achievements and new upstream research ideas.

The EASN Association


The long-term goal of establishing EASN was to built up an open, unique European platform in order to structure, support and upgrade the research activities of the European Aeronautics Universities, as well as to facilitate them to respond to their key role within the European Aeronautical research Community in incubating new knowledge and breakthrough technologies. The European Aeronautics Science Network principles have obtained the support of the commission thanks to two funded Specific Support Actions.

On 06.05.2008, the EASN Association was officially established which is:

- An International association based in Brussels
- Self funded and self sustainable
- Coordinated and run by a board of directors which is elected by the General Assembly for a 3 year term

Eucass wishes a successful conference to our colleagues at EASN.

H2020, Open Science and the changing road ahead for scientific publishing in the EU

A very recent meeting held in Brussels (May 26-27 2016) by the European Competitiveness Council (COMPET) could become a pivotal point on the history of scientfic publishing in Europe. The provional version of the outcome  of the council is possibly not sufficient to grasp the profound implications that the decisions taken could bring if the right conditions are met and the directives implemented correctly.

Other press releases and statements try to put in a better perspective and illustrate more the disruptive nature of the changes discussed in the Council. See for example the title of a press release present in the website of The Netherlands rotating EU presidency: All European scientific articles to be freely accessible by 2020.

The basic idea is that scientific papers (and the underlying data) would foster better research and innovation if they were freely accessible under the concept of Open Science. This concept is not new. Since years the EU has been experimenting and testing the principles, for example sponsoring some FP7 projects publications via some post-grant funds.  The following schema, used many times in EU commissions pubblications, (i.e. from here), illustrates well the difference between knowledge witheld for patenting purposes, private publishing, and open access.

This schema illustrates as well some of the issues with the current definition of Open access to scientific data: Gold open access requires immediate access to the scientific paper at the time of the publication (i.e. on a traditional archival peer reviewd journal), while a Green open access would allow a transitional period ("embargo"), during which the access is restricted.

All the difficulties will come from a rational determination of the period of time during which the embargo could be effective: months or years, depending from the field of research could be excessive.

Beside a free, unrestricted access to the scientific paper, the data used for the research is as well part of the bigger picture: typical scenario, a paper researches some data, and draws some conclusions.

Whithout the underlying data, it is very difficult for others to replicate the study findings to determine if they are indeed sound, or if intellectual or calculatory mistakes have been conducted. Beside the immediate concerns about the correctness of the published analysis, the most interesting aspect is the possibility of analyzing old data via newer techniques and methodologies. 

But of the whole data generated or analyzed during a scientific study, how much and which to preserve, and how? The commission in the H2020 framework has introduced the concept of Data Management Plans that help with some guidelines the choices of the researchers. Up to the last council meeting, not all the project hads to publish all (or part) of their data, only those that participated to the Open Data Pilot (see the announcement of 2013 on the topic). It is clear that following these directives for researchers will be a novel experience, and it will be interesting to see how they are implemented.

Finally, the scientific papers and the underlying data, to be made freely accessible must be stored somewhere online (the so called trusted repositories), for example on the European Open Science Cloud.

In reality, as long a set of reccomandations and interoperability are respected, each institution could host its own data, so long as the access is guaranteed to third parties.

Currently it is too early to know how fast the recent decisions will impact science in the EU: will the quality of scientific publications suffer, without the help of established scientific editors? Will the embargo period be too long? Is this a disruptive change introduced by the EU?

Many of our readers are already confronted with H2020 projects, maybe even with Open Data Pilot Projects. Possibly, at the end of their projects, when all is said and done, it would be interesting to ask them their impressions and feelings on this topic.

Feel free to contact us at any time to discuss this topic!


Recently Published Patents of Interest

Topic: iBeacon

The following patents have been selected from the EPO database using the following criteria:  "WORD = ibeacon AND PUA12 >= 20160101". In this case, this means all patents whose A1/A2 documents have been published after the first January 2016, with somewhere in the text ibeacon. Since patents can be filed towards different organizations, sometimes the data available in the EPO database (the version available for free online) is not the most complete. In that case an external link is used.

What is an iBeacon and why we think it is worth of interest?

The answer is pretty simple: ubiquitous smartphone usage has given the masses access to  GPS/GLONASS, maybe soon Galileo and BeiDou, globan navigational systems.

The reliance on such tools is sometime so extreme that we start talking more and more as well of Death by GPS.  

Global positioning, together with crowdsourcing techniques, can severely alleviate congestion in some highly frequented roads: one needs only a smartphone, a signal from your selected constellation, and a special application to do smart driving. Obviously, for crowdsourcing to work, the more people are using a particular system, the better. There are some implication of the market dominance of a particular application over the others in absence of a free exchange of data with other applications, but this cannot be discussed here.

What cannot be achieved with a smartphone alone, is an indoor navigation/indoor positioning system. As a global navigational system requires a constellation of satellites with well known positions in time and signals, an indoor positioning system requires some devices, with a well known location in space, that need to talk to the smartphone.

The term iBeacon is a protocol developed by Apple, and that many use on LE Bluethoot devices. Indoor positioning systems are still on their infancy, but it is possible to imagine that in the future you could navigate inside a building, i.e. an airport and sit inside a plane knowing where your luggage is under your feet in the carbo bay.

Currently some home automation systems use an iBeacon (where here we use interchangeably the name of the protocol and the device) to determine whenever a person is at home or not, when the navigation system of the smartphone cannot be trusted.

An iBeacon device can indeed be used both as a moving object or as a reference point, depending from the needs.

There are some privacy and technological issues to overcome, but who could have imagined years ago what could you do with a GPS today? Therefore patents on this field could be of extreme interest to guess how to the technology will evolve tomorrow. See below a selected few. 

How to browse the EPO patent list

There are different tools online to browse/search patents, for example google and the wipo. Here we will be using the EPO Patent information services for experts, from this address. It is possible to browse patents based on many parameters, inventor name, applicant/proprietor (usually a company), application date, etc. etc.  In the future we will consider patents that have published their A1/A2 documents since the date of the last newsletter.

The definition of A1 and A2 are available here.

  • Basically when a European patent application is published together with the search report done by the agency, it is known as an A1 publication. When this application is published without the search report, it is an A2 document.
  • The search report is then published later as an A3 document.
  • When the patent is granted, it is published as a B document.
