The Instrumented Indentation Test is based on simultaneous recording of force and indentation depth, obtained during test cycle. The force-depth curve, describing the indentation pattern, is typically formed by two parts having the “zero-point” in common, i.e. the first contact point between the indenter and the surface of test piece. The zero-point determination is a crucial aspect for Martens Hardness evaluation, so that relevant ISO standard suggests to estimate it by extrapolation of polynomial fitted functions. In this paper a new model, based on a segmented function, is proposed. This approach implies the use of maximum likelihood estimator for parameters determination. The corresponding uncertainty is provided through the covariance matrix of the regression model.

The paper describes the newly developed "NMi TraSys" - NMi Traceability System. This travelling carrier & multiplier of traceability has been realized to embody a significant part of the Dutch National traceability-chain for high-pressure gas-flow measurements. The number of contributions of uncertainty as well as their values, due to "copy-losses" and "installation-effects" during the traditional transfer of traceability from one facility to another, are decreased.
First results are presented about observed repeatability and reproducibility, uncertainties and consistency checks. The device will include in time, reference values of three different independently realized primary standards (viz. DDD - Dynamic Displacement Device, GOPP – Gas-Oil Piston-Prover and NMi TraSys itself). With internal harmonization processes at NMi VSL with "input" reference values from the three other primary standards, viz. DDD-conventional, DDD-extended pressure level and GOPP, the aim of 0,1% uncertainty at 4.000 m³ / h and p = 60 bar is within reach. This will improve the uncertainty as well as the stability of the Dutch National reference values considerably.
NMi TraSys will be used as a set of Travelling Reference Meters, creating an efficient availability of stable and validated Harmonized Reference Values for high-pressure gas-flow.

We had already expressed the importance of “Measurement Science” .on the education to rise up the scientific sense for the people live in the society carried on natural science, technique and information. It is the liberty to apply how “Science” to the Education, an answer is in this paper. And we had reported the contents by some papers. This paper suggests the usefulness of application of “Measurement Science” for the stage 1 and stage 2 education (Compulsory Education) and the stage 3 education (Semi-Compulsory Education), when classify National Education in 5 stages.

The aim of this paper is to present the participatory project "Sicilia Beni Culturali" on the izi.TRAVEL platform, launched in May 2016 and well known on social media as #iziTRAVELSicilia. Recognized as a facilitator of best practice digital promotion and valorization through storytelling and crowdsourcing culture, it has already involved thousands of people. With over 150 audio guides produced on the platform in just over a year, #iziTRAVELSicilia has become a real model of participation in co-creation of cultural values, by practicing the principles set out by the Faro Convention. In this paper we briefly present the project and the example of the Roman Villa of Durrueli and how this platform was and can be furtherused for the dissemination of existing 3D models and for new 3D models, such as those made by the USF - CVAST virtualization project in Sicily.

A temperature controlled 1 %Omega;–10 k%Omega; Standard resistors setup was developed at National Institute of Metrological Research, (INRIM). The aim of this realization was the involvement of the setup resistors in the traceability transfer process to high accuracy multifunction electrical instruments used in Secondary Electrical Calibration Laboratories or even their use as primary Standards in high level Laboratories or Institutes. The 1 %Omega;–10 k%Omega; Standards are formed respectively by two 10 %Omega; and 100 k%Omega; parallel connected resistors nets inserted in a temperature controlled aluminium box. Construction details, temperature and power coefficients, stability data and preliminary mid-term use uncertainty budgets of the two setup Standards are given. Their first short time (2 h) stability were on the order of few parts of 10–8. A test to calibrate a multifunction calibrator gave satisfactory results.
