An approach to set up an appropriate and optimal national infrastructure for measurements related to quality of life in Slovenia is described. It is based on an analysis of the needs of the global society, of the national needs and priorities and on the national capabilities. The implementation of the conclusions into practice has started. As in general measurements in chemistry and microbiology were not yet systematically tackled, the approach given here might serve as a model to enable other countries to establish a suitable national metrology infrastructure, which would adequately support...

The paper presents a robust methodology and an integral strategy to develop optimal metrological infrastructures in unstable economic environments and imperfect markets, as those presented in developing economies. This methodology can be applied at two levels: I.- Within an organization, e.g. an industry or company, and II.- Within an economy, e.g. an economy, country or region. The methodology is the MESURA® Program which is applied by metrology consultants to particular organizations and the corresponding strategy is the creation of a laboratory network based on a franchise scheme, the...

Standards Organisation of Nigeria (SON) was established by Decree No. 56 of 1971, and with three amendments in 1976, 1984 and 1990, the body corporate, has the sole responsibility for National Policy on Metrology, Standards, Testing and Quality Control (MSTQ). SON is the custodian of all product, process and metrology Standards in Nigeria.

The development of metrology infrastructure in African Member States has been the mandate given to ARSO by the African Union (AU) previously the Organization of African Unity (OAU) in its Treaty. ARSO fulfils this role through coordination mechanism that harmonizes the sub-regional metrology programmes, arrangements of training of personnel with the support of cooperating partners and African Governments. ARSO ensures, through its programmes the maximum sharing of facilities among African Member States in order to enhance the measurement capabilities of countries in the African economies for...

The paper describes recent developments towards a global metrology system. The driving forces behind this development are globalization and the liberalization of trade. The World Trade Organization, WTO, with more than 140 member states sets the rules for international trade. Other international organizations must take into account these rules and especially, the Technical Barriers to Trade Agreement. The organs of the Metre Convention developed a system to ensure worldwide traceability and mutual recognition of measurements and calibrations. Details of the system and measures to establish...

A technique had been previously developed, based on magnetic field measurements using a SQUID sensor, to localise in three dimensions steel needles lost in the human body. In all six cases that were treated until now, the technique allowed easy surgical localisation of the needles with high accuracy, decreasing by a large factor the surgery time and also reducing the generally high odds of failure. The method is accurate, non-invasive and innocuous, with clear clinical importance. In this paper we present preliminary measurements performed with a fluxgate magnetometer instead of a SQUID.

A new ultrasound wireless positioning system is developed that gives the surgeon the exact location and orientation of the instruments in the patient. The measuring system employ ultrasound markers placed on the instruments, outside of the human body. Knowing the dimensions of the usually rigid instruments it is possible to calculate their position and orientation inside the patient from the markers’ positions. Using the cross-correlation method we obtained a resolution of 0.7 mm in determining the marker positions. To eliminate wiring to the tools a wireless radio wave (RF) system is used...

This paper deals in its first part especial requirements which must be fulfilled by gearboxes being used in applications demanding very high accuracy: uniformity of motion, exactly described hysteresis loop, limited vibrations and good efficiency. In the second part the basic conception of a realised experimental stand is described. The stand allows to perform all measurements, data acquisition and evaluation mentioned later. The control of all components of the measuring stand and the necessary data processing and final presentation of results is performed by a PC.

The techniques for digital image acquisition and digital image processing used to identify defects in transparent elements are described in the paper. The block diagram of the test set-up, algorithm of the software developed for identifying geometrical parameters of defects are presented here. The set-up, presented in the paper is proposed for glass quality production control at final and intermediate production line of double glassed windows. The other applications are foreseen. One of the very important feature is calibration of the image with the use of reference glasses, light correction...
