A comparative study of energy consumption for lighting according to\ud prEN 15193-1
Full text linkThe purpose of the diploma work was to put to the test the prEN 15193-1 draft standard. The draft standard was thus examined in its original English version, with only the main requirements being translated into Slovene. In addition to the prEN 15193-1 draft standard, I have also studied the CPD 89/106/EEC and EPBD 2002/91/EC directives, on whose basis this particular draft standard was developed. Considering the requirements of the draft standard, I developed an Excel computer program, which calculates energy consumption for lighting in a given building. The program has the options of calculating monthly or annual consumption. The computer program was tested on three different types of buildings with the purpose of establishing the appropriateness of the prEN 15193-1 draft standard requirements. The analysis of these calculations has led to the conclusion that the prEN 15193-1 draft standard is not entirely accurate and can be used primarily to estimate lighting energy consumption. The prEN 15193-1 draft standard should therefore be adjusted and its anomalies resolved. Above all, the draft standard should consider the same level of all incoming data, this being the only means of achieving sufficiently accurate results
Evaluation of the energy efficiency of lighting insides of sports facilities based on the PN-EN 15193 norm

Report on the application of CEN standard EN 15193
No full textThe CENSE-project (2007-2010) was initiated by the European Commission to improve acceptance and use of the CEN-standards, which were developed to analyse the energy performance of buildings according to the EPBD. One of the project's major goals is to identify problems concerning the standards' content and their implementation via questionnaires and workshops and to formulate recommendations for improvement. Per cluster of standards on a specific subject technical recommendations have been prepared by the CENSE teams who focused on a specific subset of the CEN-EPBD standards. This report deals with the following standard: EN 15193: "Energy Performance of Buildings - Energy Requirements for Lighting"
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
Evaluation of the energy efficiency of lighting inside sports facilities on the basis of the PN-EN 15193 norm
No full textThe article presents the findings of energy efficiency examination of the lighting used inside the swimming pool hall of the existing water park facility based on the PN-EN 15193 norm. It describes the basic factors on which the analysis of the lighting energy efficiency is based and provides specific calculation
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
