Measurement with Persons: A European Network

The European ‘Measuring the Impossible’ Network MINET promotes new research activities in measurement dependent on human perception and/or interpretation. This includes the perceived attributes of products and services, such as quality or desirability, and societal parameters such as security and well-being. Work has aimed at consensus about four ‘generic’ metrological issues: (1) Measurement Concepts & Terminology; (2) Measurement Techniques: (3) Measurement Uncertainty; and (4) Decision-making & Impact Assessment, and how these can be applied specificallyto the ‘Measurement of Persons’ in terms of ‘Man as a Measurement Instrument’ and ‘Measuring Man.’ Some of the main achievements of MINET include a research repository with glossary; training course; book; series of workshops;think tanks and study visits, which have brought together a unique constellation of researchers from physics, metrology,physiology, psychophysics, psychology and sociology. Metrology (quality-assured measurement) in this area is relativelyunderdeveloped, despite great potential for innovation, and extends beyond traditional physiological metrology in thatit also deals with measurement with all human senses as well as mental and behavioral processes. This is particularlyrelevant in applications where humans are an important component of critical systems, where for instance health andsafety are at stake

THE IMPORTANCE OF POSITIVE IONS IN OPTOGALVANIC DETECTION WITH THE THERMIONIC DIODE AND THE GLOW DISCHARGE LAMP

L'importance des ions positifs dans le fonctionnement de deux détecteurs optogalvaniques : diode thermoionique et lampe à décharge lumineuse continue, est discutée. Les effets du temps de réponse de ces détecteurs pour une détection synchrone sont discutés et expliqués grâce à des résultats expérimentaux obtenus sur les signaux optogalvaniques en fonction du temps et de la fréquence spectrale.The importance of positive ions in the functionning of two optogalvanic detectors, the thermionic diode and the d.c. glow discharge lamp is discussed. The relevance of the finite response time of the detectors to detection with lock-in amplifiers is exemplified with some experimental results on time- and spectrally-resolved optogalvanic signals

HIGH-RESOLUTION LASER SPECTROSCOPY OF LOW-LYING P-STATES IN SR-I AND BA-I

Hyperfine structure and isotope shifts of the second excited P states of Sr I and Ba I have been measured. In addition, the Sr I first resonance line has been studied. The present results are combined with existing data on both high-lying and lower-lying excited states, in a simple parametric study of the level isotope shifts in Sr I. © 1983 Springer-Verlag

Capturing the content of physics: Systems, observables, and experiments

Abstract. We present a content markup language for physics realized by extending the OMDoc format by an infrastructure for the principal concepts of physics: observables, physical systems, and experiments. The formalization of the description of physics observables follows the structural essence of the operational theory of physics measurements. The representational infrastructure for systems and experiments allow to capture the distinctive practice of physics: natural laws are supported by evidence from experiments which are described, disseminated and reproduced by others.
