8th Brazilian Congress on Metrology (Metrologia 2015)

Abstract

THE EIGHTH BRAZILIAN CONGRESS ON METROLOGY (METROLOGIA 2015)The United Nations celebrated 2015 as the International Year of Light. By a curious coincidence, many notable events in science and technology completed a multiple of 50 or 100 years in 2015. From the pioneering work of the wise Ibn Al-Haytham in 1015, through Fresnel, Maxwell, Einstein, the discovery of the cosmic microwave background, to the use of optical fibres in communications in 1965.Electromagnetic radiation is present in our daily lives in countless applications. It is remarkable that there is no way to think about these applications without thinking of measurements. From entangled photons to more prosaic public illumination of our daily life, we are intrinsically connected all the time with the luminous phenomena. Among other things, the light allows global communication on a large scale. It strengthens the internationalization of production processes, which brings considerable changes in relations, processes and economic structures, as well as it orients the social, political and cultural behaviour of any country. These conditions of this internationalization require interchangeability of parts of complex systems, translated into strict adherence to the standards and specifications that use increasingly accurate measurement techniques, as well as the growing demand from consumer markets for products and higher quality services. They also require innovation and improvements in domestic production to boost the competitiveness of industries in domestic and foreign markets. Thus, if the Science of Measurements is taken as a serious concern, countries are better prepared to evolve towards economic and social development.In this 8th edition of the Brazilian Congress on Metrology (METROLOGIA 2015), in addition to the thematic sessions in various areas of Metrology and Conformity Assessment, we hold several satellite events. They are already traditional events or highlight important current issues such as those relating to the International Year of Light. The events are meetings on Electricity (XI International Seminar on Electrical Metrology - SEMETRO), Ionizing Radiation (II Brazilian Congress on Ionizing Radiation - CBMRI) and the Meeting of the Brazilian Chemical Metrology Network (REMEQ).As in previous events, we hosted the Expo Metrology 2015 trade show and an exhibition of measuring equipment. During the conference, short courses in various areas of interest in Metrology and Conformity Assessment were given, organized by the Basic Industrial Technology National School - ENTIB, an initiative from the Brazilian Society of Metrology (SBM).The 8th Brazilian Congress on Metrology consisted of Keynote Speeches (6) and regular papers (292). Among the regular papers, the 100 most outstanding ones, comprising a high quality content on Metrology, were selected to be published in this issue of the Journal of Physics: Conference Series.With tremendous satisfaction and gratefulness, the organizers of METROLOGIA 2015 would like to present this volume of IOP Journal of Physics: Conference Series (JPCS) to the scientific community to promote further research in Metrology. We believe that
