The use of simulation tools in teaching lighting system design
No full textThe recent technological advancements in the fields of Information Technology have given us exciting opportunities for knowledge gathering and knowledge sharing. This paper presents the use of simulation software DIALux in teaching Electrical Engineering subjects in general and Energy efficiency aspects in particular. A typical office room in AbuDhabi in the United Arab Emirates (U. A. E) is selected and the use of DIALux software for teaching lighting system design is explained. It is expected that the proposed teaching methodology of computer-based simulation of office lighting system design shall enhance motivation, increase deep-learning skills of Electrical Engineering graduates, promote independent learning skills and stimulate life-long learning.</p
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
Novel techniques for voltage stability assessment and improvement in power system / Ismail Musirin.
Full text linkThis thesis presents novel techniques for voltage stability assessment and improvement in power system. A novel line-based voltage stability index termed as Fast Voltage Stability index (FVSI) was developed and used to evaluate the voltage stability condition on a line. The value of FVSI was used in order to determine the most sensitive line and corresponding weak us in the system. The results obtained from the voltage stability analysis using FVSI were utilized to predict system violation, identify most sensitive line corresponds to a load bus and estimate the maximum load ability and operating margin in the system. A new Evolutionary programming (EP) based acceleration search algorithm was developed to accelerate the process in estimating maximum load ability in a power system. The maximum load ability estimated from the proposed acceleration search technique was found in a good agreement with those obtained from the conventional voltage stability analysis technique. The application of FVSI was extended for the evaluation of the overall system stability and determination of loaded buses in a radial distribution system. The effect of reactive power load variation on total losses in the system was also investigated. The proposed FVSI was consequently used as the line outage severity indicator in the implementation of contingency analysis and ranking. Few automatic contingency analysis and ranking algorithms due to line and generator outages were separately developed. These algorithms have profoundly reduced the computation burden experienced in the conventional technique. Finally, a novel Reactive Power Planning R.PP) algorithm using the state-of-the-art of EP for voltage stability improvement was developed. The FVSI was used as the objective function for the developed optimisation technique. A performance comparison in terms of loss minimization and voltage stability improvement was made when loss minimization was taken to be the objective function. It was found that the proposed algorithm with FVSI as the objective function has been able to produce a better result as compared to the techniques developed in the literature
