Research programme Metrology and Quality considers metrology, science of measurements, as a generic scientific discipline in order to improve quality of specific targeted scientific areas and implement the results with the respect to the three EU grand Challenges: Industry, Environment and Health. Measurements will assure a complete measurement result which is traceable to higher level standards. Traceability evaluation includes measurement uncertainty analysis, which is often not completely resolved and understood, especially in new emerging areas. All the hypothesises will be theoretically proved, experimentally confirmed and implemented in thermometry, electromagnetic measurements and sensory (perception based) measurements. In the area of thermometry (temperature, humidity, thermal flow) the programme group also acts as national measurement standards laboratory for thermodynamic temperature. In certain ranges the group has already achieved some best measurement capabilities in the world (published in the KCDB (Key Comparison Database) of the International Bureau of Standards BIPM (Bureau International des Poids et Mesures) at kcdb.bipm.org). The research in thermometry will additionally tackle very high and very low temperatures and humidity at lowest possible uncertainties for future industrial needs. Research in electric measurements (electricity, magnetism, acoustics) will examine the electromagnetic influences on the instrumentation, develop new algorithms for shortening the measurement time and decrease sensitivity of influential quantities on periodic signals, to enable novel digital instrumentation solutions. Acoustic measurements comprise of infra sound, audio sound and ultra sound, including acoustic approach to temperature measurements at the secondary level. Sensory measurements (sensory, perception-based measurements) are considerably different from traditional measurements due to the enhanced influence of human behaviour and nature in the measurement process, where humans are either acting as measurands or measuring devices. These facts are imposing new and yet unresolved measuring requirements, while still requiring traceability, comparability, repeatability and reliability of measuring results, in order to enable reliable decision making. The research programme as a whole deals with the development of new measurement methods and technologies and implementing solutions in all three targeted areas. The objective of the programme is to contribute to the basic measurement science by multidisciplinary and interdisciplinary approach and to transfer established measurement solutions beyond existing areas of interest. By rigorous analysis of uncertainty contributions and creation of complete measurement results, enhanced reliability of measuring results will improve decision making and quality in several areas, therefore contributing to greater European competitiveness and quality of life in Europe.
Significance for science
Metrology, the science of measurements, as an independent scientific discipline must develop in areas like: i) measurement theory) e.g. measurability of a phenomena, units and scales), ii) measuring methods and measurement instrumentation (e.g. novel types of reliable and accurate measurements, new measuring principles and novel measurement devices, traceable to existing reference devices) and iii) advanced analysis of measurement results, used for experimental verification of new findings and a foundation for further decision-making (e.g. measuring uncertainty budget, evaluation of a product or service, assurance of target uncertainty). Development of metrology is crucial for validation of new scientific findings in various research areas. At the same time accurate and traceable measurements represent the basis for development of technology. Gained new knowledge is the foundation of international system of units SI development (e.g. definitions, realizations, dissemination and maintenance of units). Development of metrology as an independent scientific discipline is therefore directly related to development of many other scientific disciplines, for measurement results regardless of the scientific discipline, are unreliable, if not accompanied with the measurement uncertainty. In the field of thermometry, importance for the development of science is in development of measuring methods and measuring instrumentation for temperature measurements of extremely high and extremely low temperatures and extremely high and extremely low humidity levels. In conjunction with recent redefinition of the unit of thermodynamic temperature kelvin, now based on Boltzmann constant, studies of dissemination of results to the industrial level, realisation of temperature fixed points, dynamics of thermal quantities and humidity measurements in gases and materials, are possible. In the field of electrical measurements new solutions of digital instrumentation will be available (e.g algorithms for shortening of measurement time, while ensuring the robustness of the signal parameters estimation and reducing the sensitivity to the disturbing quantities of periodic signals), and temperature measurements by means of acoustic thermometers. By inclusion of physiological and psychological parameters of human, the findings in sensory measurements represent foundations of measurements, currently without agreed scales and units, but already used by industry and service (e.g. measurements of motivation, sickness, annoyance). In the field of quality engineering the most important contribution is introduction of a scientific approach for confirmation of correctness of testing and applied test methods (e.g. in testing of safety of electrical appliances).
Significance for the country
using adequately prepared and uniformly understood standardised procedures, is needed. Planned research of the group in this field is focusing on gaining new knowledge in uniform comprehension and correct usage of the relevant documents. Due to insufficiency of classical energy sources, energy efficiency of buildings is gaining on importance in our society. The basic energy efficiency determination involves thermographic camera measurements. At the moment there is no consensus on calibration procedures and problems of traceability of these cameras. Therefore, it represents an important field of research of the group. In the field of improvement of basic measurements in medicine and consecutively quality of life measures, the group is focused on metrological characterisation of sensory (psychophysiological) instrumentation in terms of traceability of measuring devices and standardisation of measurement methods. Indirect importance of the programme Programme group leads and coordinates a graduate study programme of Quality Engineering in the scope of University of Ljubljana, Faculty of Electrical Engineering and lectures a number of graduate, postgraduate and doctoral courses from various fields of measuring techniques, measuring instrumentation, measuring systems, standardisation and quality assurance. As a form of the group’s knowledge transfer to industry, different study seminars and hands-on workshops in the field of metrology and quality are organised as a support for Slovenian industry and various public sectors. Members of the programme group are active in a number of standardisation technical committees and thus contribute to standards improving quality of life in modern society. Intensive cooperation with a number of international metrology laboratories reflects excellent connection of the programme with developments in the world. The group cooperates with foreign national metrology institutions and universities. Its members are active and relevant participants in important European and international metrology organisations (BIPM, IMEKO, EURAMET, OIML).
