Vantage Practice
No full textIn baansporten is de laatste jaren een ontwikkeling gaande om tijdregistratie te digitaliseren door het gebruik van transponders en detectielussen in de baan. Daardoor zijn nieuwe mogelijkheden ontstaan om ook naast het wedstrijdmoment de sportprestaties in te zien. Gedurende dit project is gewerkt aan een applicatie die op een overzichtelijke manier inzicht geeft in trainingen van eigen prestaties, maar ook de prestaties van andere sporters. Daarnaast bevat de applicatie een sociale component, waarmee sporters gemotiveerd worden om te blijven of te gaan sporten.Computer ScienceElectrical Engineering, Mathematics and Computer Scienc
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
A non-centralized approach to Video on Demand on mobile devices
No full textAs mobile Internet traffic continues to consistently gain on desktop traffic in terms of volume, a desire for a mobile version of Tribler was expressed by the Client: Dr. Ir. Johan Pouwelse. This desire was formulated into a Bachelor project, which will be executed within a period of 11 weeks. The project is centered around answering the following research question: "How can we make video-on-demand available for mobile devices using a non-centralized approach?". The goal of the project is to make a prototype of a mobile application for Android that features Video on Demand through a Peer-to-Peer network. During the design- and implementation phase of the project, several methods are used, such as Scrum, acceptance testing and MoSCoW prioritization. Additionally, Git is used to keep track of the history of all documents and source code. During the implementation phase, Libtorrent was implemented together with VLC to create the prototype. This prototype can stream videos on Android in a non-centralized way, and therefore answering the main research question. The application meets the `must have' requirements as well as some of the should have requirements, which were elicited in the requirements.Parallel and Distributed SystemsElectrical Engineering, Mathematics and Computer Scienc
Performance Optimization of Multi-Tenant Software Systems
No full textMulti-tenant software systems are Software-as-a-Service systems in which customers (or tenants) share the same resources. The key characteristics of multi-tenancy are hardware resource sharing, a high degree of configurability and a shared application and database instance. We can deduct from these characteristics that they lead to challenges compared to traditional software schemes. To better understand these challenges, we have come up with a reengineering pattern for transforming an existing single-tenant application into a multi-tenant one. We have done a case study in which we transform a single-tenant research prototype into a multi-tenant version. This case study showed that in a layered application, this transformation could be done in less than 100 lines of code. With a better understanding of the challenges inflicted by multi-tenancy, we have focused on one of these challenges in this thesis, namely performance. Because tenants share resources in multi-tenant applications, it is necessary to optimize these applications on two levels: (1) at the hardware level and (2) at the software level. In this thesis, we present and evaluate methods to analyze and optimize the performance of multi-tenant software on those two levels.Software TechnologyElectrical Engineering, Mathematics and Computer Scienc

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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
