VDA 5050 - Eine Analyse und Einordnung
No full textDurch das Industrial Internet of Things hat sich die Intralogistik stark verändert. Wo zuvor konventionelle Gabelstapler fuhren, fahren jetzt Fahrerlose Transportfahrzeuge. Diese Fahrerlosen Transportfahrzeuge werden von vielen verschiedenen Firmen hergestellt und haben eine komplexe Steuerung. Dies hat zur Folge, dass es kaum möglich ist, Fahrzeuge unterschiedlicher Firmen miteinander zu kombinieren. Es fehlt also an Interoperabilität zwischen den Systemen. Das Ziel der vorliegenden Arbeit ist es, die standardisierte Schnittstelle VDA 5050, die Abhilfe im Bereich der Interoperabilität schaffen möchte, zu analysieren und einzuordnen. Dabei soll die Frage beantwortet werden, welche spezifischen Merkmale die VDA 5050 auszeichnen und welche Gemeinsamkeiten und Unterschiede sie im Vergleich zu anderen bestehenden Kommunikationsstandards hat. Um dieses Ziel zu erreichen, wurde eine systematische Literaturrecherche durchgeführt. Dabei wurden die Standards MQTT, Robotics Middleware Framework, MassRobotics Interoperability Standard und OPC UA gefunden. Diese Standards wurden anschließend mithilfe einer Nutzwertanalyse miteinander verglichen. Dabei wurde deutlich, dass die VDA 5050 Gemeinsamkeiten und Unterschiede mit anderen Standards aufweist. Die Ergebnisse dieser Arbeit vertiefen das Verständnis für die VDA 5050 und zeigen auf, wie verschiedene Standards das Interoperabilitätsproblem lösen wollen

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
Photometry and imaging of the peculiar planetary nebula IRAS 21282+5050
Get PDFWe report visible, near-infrared, and mid-infrared photometry of the IRAS planetary nebula 21282+5050. Narrow-band photometry at 10 μm confirms the presence of the 11.3 μm PAH feature. IRAS 21282+5050 belongs to a small group of planetary nebulae with WC11 nuclei and PAH emission. The spectral energy distribution shows that majority of the flux is emitted in the infrared, and the object has one of the highest infrared excesses among all planetary nebulae. Optical imaging (after subtraction of the central star) reveals a nebula of size of ∼7″ × 5″ which is elongated along the N-S direction.published_or_final_versio
