No full textThe ISO standards for the Geometrical Product Specification and Verification (GPS) define an internationally uniform description
language, that allows expressing unambiguously and completely all requirements for the geometry of a product with the corresponding
requirements for the inspection process in technical drawings, taking into account current possibilities of measurement and testing
technology. The practice shows that the university curricula of the mechanical engineering faculties often include only limited classes on
the GPS, mostly as part of curriculum of subjects like Metrology or Fundamentals of Machine Design. This does not allow students to
gain enough knowledge on the subject. Currently there is no coherent EU-wide provision for vocational training (VET) in this area.
Consortium, members of which are the authors of this paper, is preparing a proposal of an EU project aiming to develop appropriate

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Training in the aeronautic industry for geometrical quality control and large scale metrology
No full textAdvanced manufacturing of aircraft, and the large parts needed in this field, is based on multiple suppliers located in different countries and continents, intensively using automation, data exchange, advanced manufacturing technologies embedded in the digital era. Several national and international initiatives (e.g. Industrie 4.0) are oriented to support this effort and development. New opportunities for advanced manufacturing of aeronautic products are based on measuring technologies for Geometrical Quality Control and Large Scale Metrology. In the Aeronautic Industry they are an essential tool for the implementation of the initiatives in modern product engineering and process control. To operate, programme and manage the most advanced measuring systems, highly competent and skilled personnel is required. The authors will describe new developments in the framework of the international project "WINGS+", addressing the training needs of the Aeronautic industry, and suggest innovative training solutions with focus on the competent use of relevant measuring systems.</p
An integrated framework of reference for the qualification of personnel in coordinate metrology
Get PDFAdvanced measuring equipment, such as Coordinate Measuring Machines, Computed Tomography, Fringe-projection, Photogrammetry, Laser trackers and other systems are essential in manufacturing for both product/process engineering and quality control. Competent personnel are essential to use these systems effectively and efficiently, and their training is a key element of attention in industry. The paper illustrates a proposal for an integrated framework of reference for the qualification of personnel in Coordinate Metrology, having the aim of increasing confidence of employers in qualifications and the recognition of specific competences acquired in different companies and countries. A summary of learning outcomes for Computed Tomography is presented as example
