Automatic visual inspection
No full textIn this thesis we introduce the subject of automatic visual inspection. While automation is not new in the process industries it is only just making its presence felt in the batch and discrete parts manufacturing industries. An integral process in discrete parts manufacturing is that of inspection which of necessity must be automated if complete automation is to be achieved. Here we are concerned with the replacement of the visual and interpretative processes of the human inspector by computer-based systems with image acquisition and image analysis capabilities. Research into automatic visual inspection requires the setting up of a laboratory in which the many varied aspects of the subject can be investigated. These include image acquisition, lighting, optics, mechanical handling, image processing and algorithm development. The digitisation and display of images is a vital prerequisite for such a laboratory as indeed is the provision of a comprehensive range of image processing functions. The thesis describes such a laboratory together with provisions for its hardware and software. It describes the research into two application areas of automatic visual inspection which have been investigated in the laboratory. The first of these is the shape analysis of essentially flat objects using a technique called the concavity tree description of shapes. This application focusses on those objects that can be inspected by inspecting their silhouettes so that binary (2 level) images are readily obtained. The second application is the inspection of glassware where considerable importance is attached to image acquisition. In this application the emphasis is on the rapid processing of the gray scale (multilevel) image to produce a binary image which can be analysed for the defects we are looking for.</p
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
Variations 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

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
