Acknowledgements I’d like to thank all of the people who have supported and help me to make this thesis possible. Firstly and foremost, I am deeply indebted to my supervisors, Prof. Dr.-Ing. Uwe Schwiegelshohn and Dr.-Ing. Ramin Yahyapour. During the last 3 and a half years, they have always encouraged and motivated me, given valuable advices to me. I owe my whole research progress to their efforts. I also want to thank Prof. Dr. habil. Sergei Gorlatch for his helpful support. Further, I would like to thank for the help of the all of the other colleagues in the information technology sector, institute for robotics research. They provided me a very pleasant working atmosphere. It is a cherishable memory to work with them in my life. Also I would like to thank for the finical support from the Graduate school of production engineering and logistics, university of Dortmund. The help from the colleges from graduate school is highly indebted
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
How to Design a Job Scheduling Algorithm
No full textAbstract. We discuss the components of a general approach to design algorithms for resource management in parallel processing systems. Starting from the observation that in this area the average influence of research publications on practical implementations is negligible, we address the three main categories constraints, objectives, and evaluation. For each category, we describe common approaches and restrictions and give some general rules that should be followed when presenting a new algorithm for resource management. As an example we present a resource management method for the IaaS model of Cloud Computing that extends the spot instance approach of Amazon. For this example, we first discuss technical, organizational, and usage constraints based on existing concepts and research results. Then we briefly describe resource management objectives from the viewpoint of a provider. After presenting our algorithmic concept, we show that an evaluation with theoretical means can also yield meaningful results in practice
