    Elektronik und Firm-/Software wird mit spezialisierten Anforderungen in vielen For-schungsprojekten benötigt. So haben viele Forschungszentren und auch Universitäten Entwicklungsgruppen, die sich diesen Aufgaben stellen. Auch gibt es In-dustriebetriebe, die spezialisierte Beiträge beisteuern. Mit der Idee, dass man indiesem Umfeld von einander profitieren und zusammenarbeiten kann, treffen sichjedes Jahr einmal Techniker/-innen, Ingenieure/-innen und Wissenschaftler/-innen,um sich mit Vorträgen, einer Ausstellung und Gesprächen auszutauschen. Organisiert wird die Tagung von den Helmholtz-Zentren, offen für andere Vortragende und Teilnehmer/innen. Dieses Jahr war das ZEA-2, Systemhaus für die Forschung, am Forschungszentrum FZJ in Jülich der Gastgeber.Es waren sechs Helmholtz-Zentren, DESY, FZJ, GSI, HZG, HZDR und KIT, vertreten. Daneben nutzten Universitätsvertreter/innen die Gelegenheit des Austausches. Die Industrie präsentierte auf High-End Anwendungen spezialisierte Geräte und waren für viele Fachgespräche offen. Die Thematiken der Tagung umfassten: - Schnelle Datenaufnahme, -verarbeitung und -übertragung, - ASIC's zu Datenübertragung und spezifischer Messsignalaufbereitung, - Kontrolle von Aktoren und Auslese langsamerer Sensoren- Fertigung von Elektronik und Geräten mit Elektronik, - Kooperation zu Entwicklungen mit der Industrie, - Wie testet man Elektronik und Firm-/Software? An einem halben Tag wurde ein Technikbetrieb zur Papierverarbeitung besichtigt. Auch da wurde gezeigt, dass die Steuerung von Maschinen anspruchsvoll ist und teils ähnliche Aspekte wie die Steuerung der Forschungsanlage aufweist. Das Tagungsprogramm ist auf dem Internet einzusehen: https://indico.desy.de/indico/event/22503/ oderhttps://indico.desy.de//event/SEI 2019. Die Homepage der Studiengruppe ist auf http://sei.desy.de/ zu finden. Ein Workshop über "Testen" diente dem Austausch, wie man sich zum einen der Vielfalt der spezialisierten Geräte effizient stellt und spezifische Eigenschaften im Testerfasst, und zum anderen doch von Wiederverwendbarkeit und Standards profitiert

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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

    Status and Commissioning of the Wire Scanner System for the European XFEL

    No full text
    The European-XFEL (E-XFEL) is an X-ray Free ElectronLaser facility located in Hamburg (Germany). The superconductingaccelerator for up to 17.5 GeV electrons will provide photons simultaneously to several user stations. Currently12 Wire Scanner stations are used to image transverse beamprofiles in the high energy sections. These scanners provide a slow scan mode which is currently used to measure beam emittance and beam halo distributions. When operating with long bunch trains (>100 bunches) also fast scans are planned to measure beam sizes in an almost nondestructivemanner. This paper describes the current installations and the latest developments of the system at European-XFEL.Furthermore, the commissioning status of the system andf irst results of beam halo studies will be shown

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
