El uso de Internet en las bibliotecas del CSIC

En este artículo nos proponemos hacer una reflexión sobre el efecto que ha tenido Internet en el panorama bibliotecario del CSIC (Consejo Superior de Investigaciones Científicas). Para ello es necesario hacer referencia al importante proceso de informatización que se ha operado en los 10 últimos años en las bibliotecas del CSIC y que hoy nos permite poder hablar de una red de bibliotecas consolidada

Contributions of precision engineering to the revision of the SI

All measurements performed in science and industry are based on the International System of Units, the SI. It has been proposed to revise the SI following an approach which was implemented for the redefinition of the unit of length, the metre, namely to define the SI units by fixing the numerical values of so-called defining constants, including c, h, e, k and NA. We will discuss the reasoning behind the revision, which will likely be put into force in 2018. Precision engineering was crucial to achieve the required small measurement uncertainties and agreement of measurement results for the defining constants

Investigation on the International State of the Art of Micro Production Technology

The study “microPRO” dealing with the international state of the art of micro production technology was conducted by the above named Institutes. The objective of this study was to determine the worldwide state-of-the-art technology and research in micro production technology by means of scientific investigations and technical discussions with the technology leaders and, based on this, to identify the required research and development as well as the future potentials of these technologies in view of the market-overlapping economic utilization of miniaturized products

Benefit quantification of interoperability in coordinate metrology

One of the factors contributing to limited reproducibility of coordinate measurements is the use of different inspection software. Time-consuming efforts for translation of part programs are sometimes needed, and interoperability of inspection equipment has the potential to reduce these inefficiencies. The paper presents a methodology for an economic evaluation of interoperability benefits with respect to the verification of geometrical product specifications. It requires input data from testing and inspection activities, as well as information on training of personnel and licensing of software. The model is illustrated using an automotive case study and the related assessment of an investment in interoperability
