Introduction to special issue on selected TC4 papers presented at XX IMEKO World Congress Founded in 1958, IMEKO is a non-governmental federation of 38 Member Organizations individually concerned with the advancement of measurement technology. Its fundamental objectives are: the promotion of international interchange of scientific and technical information in the field of measurement and instrumentation, and the enhancement of international co-operation among scientists and engineers from research and industry. The IMEKO organizes World Congresses any three years presenting papers about all the fields of measurement. The purpose of the Congresses is to bring together academia, researchers and engineers to share achievements, ideas and vision on metrology. The Congresses also provide meaningful forums for experts and professionals from all around the world to discuss topics that deal with recent advancement in the wide spectrum of metrologies. The researchers are grouped in 24 Technical Committees (TCs) with common interests in the same field. The TC n. 4 ‘‘Measurement of Electric Quantities’’, in particular, involves researchers from all over the world dealing with Electrical and Electronic Measurements. The TC-4 organizes a periodic symposium since 1990 where the most recent original proposals and research results in the field of electric and electronic measurement are presented and discussed by the scientific community. TC-4 symposia were organized in Varna – Bulgaria (1990), Wien – Austria (1992), Brussels – Belgium (1993), Prague – Czech Republic (1995), Budapest – Hungary (1996), Glasgow – Scotland (1997), Naples – Italy (1998), Lisbon – Portugal (2001), Zagreb – Croatia (2002), Athens – Greece (2004), Gdynia – Poland (2005), Florence – Italy (2008), Kosice – Slovak Republic (2010), Natal – Brasil (2011). Moreover, the papers presenting the state of the art of the research in the field of TC-4 are presented during the IMEKO World Congresses. The latest Congresses including TC-4 specialized sessions were held in Dubrovnik – Croatia (2003), Rio de Janeiro – Brasil (2006), Lisbon – Portugal (2009) and Busan – Republic of Korea (2012). The present special issue includes papers in the research field of TC-4 chosen during the XX IMEKO World Congress on September 9–14 2012, in Busan, Republic of Korea. The chosen papers have been submitted to the Measurement journal and 7 passed the review process in 0263-2241/$ - see front matter Ó 2013 Published by Elsevier Ltd. http://dx.doi.org/10.1016/j.measurement.2013.09.009
time to be published in this Special Issue, providing a small, though significant, survey of the most advanced scientific activity in this field. The papers included in the special issue represent a slicing of the state of the art of the research on several topics associated with the measurement methods for electric quantities. In particular the papers selected for the publication on Measurement journal deal with different application fields, from industrial nondestructive testing to ship power systems, to electrical trains, to primary laboratory measurements. The paper ‘‘A new concept of harmonic current detection for shunt active power filters control’’, by Janusz Mindykowski, Tomasz Tarasiuk and Xu Xiaoyan, deals with the design of shunt active power filters for solving the problem of power quality improvement in ship electrical power systems. In particular the authors propose a method for improving the precision in measuring the harmonic content for active power filter control. The paper ‘‘Time and frequency characterization of radiated disturbance in telecommunication bands due to pantograph arcing’’, by A. Mariscotti, A. Marrese and N. Pasquino, investigates on the time and frequency characteristics of radiated emissions from arcing between pantograph and overhead wire in electrical transportation systems. The authors, by means of an experimental study, observe that the radiated disturbance, in some circumstances can pose a threat to the quality of the radiofrequency telecommunication services. The paper ‘‘Analysis of the position-based quantum cryptography usage in the distributed measurement system’’, by Piotr Bilski and Wiesław Winiecki, presents the analysis of a secure transmission channel among nodes of a distributed measurement system. The channel security is discussed, using a position-based scheme, where each node is authenticated based on its geographical position. The paper ‘‘A comparison of least squares and maximum likelihood methods using sine fitting in ADC testing’’, by Ján Šaliga, Linus Michaeli, Ján Buša, Jozef Lipták, István Kollár and Tamás Virosztek, presents a simulation-based comparative study of two well known estimation methods to reconstruct the input signal of the ADC under test from

its output data: the least squares fit and the maximum likelihood estimation. Dealing with the nondestructive testing, the paper ‘‘GMR array uniform eddy current probe for defect detection in conductive specimens’’, by O. Postolache, Artur Lopes Ribeiro and Helena G. Ramos, presents an optimized uniform eddy current probe architecture including two planar excitations, with the aim of speeding-up the detection of flaws in conductive specimens. The impedance spectroscopy is currently used in fields that range from biomedical applications to corrosion analysis among others. The paper ‘‘Gene expression programming for automatic circuit model identification in impedance spectroscopy: performance evaluation’’, by Pedro M. Ramos and Fernando M. Janeiro, presents a performance assessment of gene expression programming for automatic identification of an equivalent circuit network for the measured impedance. The paper ‘‘High value resistance comparison using modified Wheatstone bridge based on current detection’’, by Ivan Lenicˇek, Damir Ilic´ and Luka Ferkovic´, presents a method for comparison of high value resistance standards by using a modified Wheatstone bridge and a picoammeter as current detector. The authors show how this method has

been adopted in a primary electromagnetic laboratory for maintaining traceability chain of reference standards ranging from 10 MX to 100 GX. The Editors of this issue and the authors are grateful to all the colleagues and institutions that have made these contributions possible. Particular thanks are due to the organizing committee of XX IMEKO World Congress. D.
