Surface quality control device for on-line applications
No full textThis paper details the development of a novel device for monitoring the quality of the metal surfaces sculptured by
modern machine tools. The developed system, that can be proposed as a machine tool accessory, integrates the three functions
of dimensional, roughness and waviness measurement. The measure is achieved, without contact, scanning the surface
with an optical measuring probe handled like an ordinary tool, which is loaded from the tool magazine and then
employed to perform the on-line measurement; a simple fibre connection to the control unit guarantees high immunity
to disturbances. The experimental validation proved the capability of the developed solution to meet the severe requirements
of the modern production systems showing the particular suitability of the inspection tool to the cases of Flexible

Electromechanical driving and braking module for a wheeled vehicle and a wheeled vehicle equipped with such an electromechanical module
No full textAn electromechanical module is provided allowing performance of both the driving and the braking function on a single wheel. The electromechanical module according to the present invention comprises in particular electromechanical driving means and electromechanical braking means controlled by a single control unit, so that electrical power may be supplied to each of said electromechanical driving and braking means. Moreover, according to a particular embodiment of the present invention, electrical power may be collected from said driving means and supplied to said braking mean
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Comparison of Combined Probabilistic Connectionist Models in a Forensic Application
No full textA growing interest toward automatic, computer-based tools has been spreading among forensic scientists and anthropologists wishing to extend the armamentarium of traditional statistical analysis and classification techniques. The combination of multiple paradigms is often required in order to fit the difficult, real-world scenarios involved in the area. The paper presents a comparison of combination techniques that exploit neural networks having a probabilistic interpretation within a Bayesian framework, either as models of class-posterior probabilities or as class-conditional density functions. Experiments are reported on a severe sex determination task relying on 1400 scout-view CT-scan images of human crania. It is shown that connectionist probability estimates yield higher accuracies than traditional statistical algorithms. Furthermore, the performance benefits from proper mixtures of neural models, and it turns up affected by the specific combination technique adopted. © 2012 Springer-Verlag

No full textVariations on the Author
Full text link“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
Full text linkWe 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
