With the XIIth QIRT conference held in 2014 and the first QIRT-Asia conference this year, it seems opportune to give a brief history of QIRT activities. The context of the birth of the QIRT conference and the ideas which were behind are first recalled. Then, the successive conferences are evoked thanks to statistic figures.

... of a radiant heat flux, it is possible to transform the image into a map of true temperature of the recorded scene. This is an ambitious aim which is often reached at the cost of limitations in the experimental conditions. Actually, it is about to support the understanding of the infrared images thanks to modelling in such a way that more parameters may be identified. This is generally reached by the use of active thermography for which the experimenter is no longer a passive observer, but an operator who introduces stimulations into the observed system and analyses the time and/or space evolution of the thermographic signal (see Figure 1). The paradox is that in this latter case, it is often unnecessary to measure absolute temperatures, just to get a radiometric level proportional to the temperature. As seen in Figure 1, the required modeling necessarily includes heat transfer modeling, but also the implementation of other physical phenomena. Heat is the source of the applicative universality of infrared thermography: heat being the result of the degradation of all forms of energy, the thermographic measurement can be linked to any possible physical phenomenon interacting with the observed system and used as a powerful measurement technique adapted to this particular phenomenon. In this sense, L.Z. Kriksunov wrote that thermography is only limited by our imagination [6]. This multiplicity of the application fields of thermography explains the fact that thermographic communications and publications are spread in many various conferences and journals without connections, making the diffusion of the thermographic knowledge difficult from one field to the others. So, the existence of a unique transverse conference, allowing people from very varied fields to meet and exchange information was of prime importance. Such a conference was already active in the USA, Thermosense, but there was a need to establish something similar in Europe to facilitate the possibilities of Europeans to participate, in particular people from Eastern Europe which were at that time in a critical economic situation. This problem of geographical proximity was recently the same for people from Asia. The solution found for Europe 23 years ago – the establishment of QIRT Conference -, which was proven to be efficient, has been re- applied, leading to the creation of QIRT-Asia. Another idea which guided us was the interest to change the location of the conference every time, so that scientists studying thermography, from all over the world, can meet each other and possibly collaborate through transnational projects. This point will be illustrated in Section 2.4. These ideas received a warm welcome from Prof. Busse (Stuttgart University), specialist of photothermal techniques, and from Prof. Carlomagno (University of Naples), specialist in fluid dynamics and NDE. The idea of a QIRT conference was born and practically realised in 1992. The first conference was organized under the patronage of the Eurotherm Committee, the aim of which was to promote and foster the European cooperation in thermal sciences by gathering thermal scientists and engineers working in specialized areas. So, this first conference was labelled as the Eurotherm Seminar 27, showing the second concern of the organizer which was the establishment of a European thermographic conference able to compete with the best international conferences in the field, the SPIE Conference in particular. This conference was particularly well welcome by the community since about 160 researchers and industrials coming from 20 countries attended it, presenting 79 papers (see Figure 2 the opening session of QIRT 1992). Among them, 62 were gathered in the book of proceedings. At the end of the conference, it was decided to hold QIRT conference every even years and Prof. Carlomagno proposed to organize the following conference in Sorrento ...

Community detection has attracted many attentions recently. Considering the effect of current network structure on the result of the recent community detection methods is useful to yield a probable performance trade-off for future algorithm selection. In this paper, we first offer a new ranking method with 3 levels for small-world and scale-free ne...
It is common for community-based free software projects to be associated with an organizational scenario that resembles “a bazaar more than a cathedral,” and to differ from the traditional, or ‘bureaucratic’ way of organizing work. This paper analyzes the governance

Since the emergence of free software in the 1980s, the belief that software should be free has been quite widely held. During this period, the software developers took the leading role. As the 1990s began, there was a notable increase in the number of general users of open source software. Furthermore, developers and distro developers (who acted as...
