No full textU uvodu se opisuju elektroenergetski sustavi te se navode njegovi ključni dijelovi.
Navedene su neke od najpoznatijih vrsta elektrana i načini prijenosa električne energije do potrošača. U
nastavku rada opisani su sustavi za nadzori i kontrolu elektroenergetskih sustava. Neki od njih su
pametna brojila, AMI, AMR sustavi čija je najčešća svrha daljinsko mjerenje količine potrošnje na strani
potrošača. Opisani su kompliciraniji sustavi poput SCADA i EMS sustava koji se koriste unutar
elektroenergetskih sustava koji služe za napajanje velikih područja te DERMS sustavi koji se najčešće
koriste u sklopu manjih sustava čija se proizvodnja električne energije temelji na obnovljivim izvorima.
Opisana je njihova arhitektura i glavni dijelovi te razni protokoli koji se koriste u komunikaciji. Kao
zadnja cjelina, navodi se povijesni razvoj i napredak elektroenergetskih sustava i opreme koja se u njima
koristi. Pruža se pogled na razvoj SCADA sustava kroz povijest i spominje se umjetna inteligencija kao
budućnost u nadzoru elektroenergetskih sustava.The basics of power systems and its key parts are described in the introduction. Most common
types of power plants are presented, alongside their key advantages and disadvantages. Electrical grid
and electrical substations are also explained in the introduction. Second part of this thesis describes
monitoring systems like AMI and AMR, but it also focuses on more complex systems like SCADA and
EMS that are used not only for monitoring, but for control and supervisory of the power systems.
DERMS is another important system that is described in this part of thesis. DERMS plays a big role in
managing power systems whose production of electrical energy is based on renewable sources of
energy. This part doesn't only describe the features of every system, it also describes their key elements
and sensors that make them precise and accurate. Last part of the thesis puts the development of
technology throughout the years into perspective. It shows how different new, modern systems are
compared with the first systems that were used. A distinction is made between different generations of
SCADA systems. Artificial intelligence is referred to as the future of managing, monitoring and
supervisory of power systems

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
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
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
