Levantamento dos impactos ambientais dos parques eólicos na região da Costa Branca Potiguar
Full text linkThe generation of wind energy has been highlighting a lot in the current scenario. Brazil is nowadays
in the world production, and the state of greater prominence in production and installation potential is
Rio Grande do Norte. A region that is currently being explored is a region of the Costa Blanca, Which is a clean and renewable energy, presents a series of environmental impacts, is dependent on the region's functionality, taking into account its flora and fauna, as well as social issues. This job moves your potential to the state of the state of the state of the species of the skylers against the state of the species. By conducting the survey, it is possible to list engineering solutions, to mitigate impacts around parks, and to improve the environment modified by developments in this sector.A geração de energia eólica vem se destacando bastante no cenário atual. O Brasil encontra-se
atualmente na quinta posição na produção mundial, e o estado de maior destaque em produção e
potencial de instalação é o Rio Grande do Norte. A região vem sendo explorada atualmente é a região da Costa Branca. Contudo, embora seja uma energia limpa e renovável, apresenta uma série de impactos ambientais, os quais dependem da característica da região de instalação, levando-se em consideração sua flora e fauna, além das questões sociais. Este trabalho busca identificar os principais tipos de impactos ambientais causados pelos parques eólicos na Região da Costa Branca Potiguar. Ao realizar o levantamento, é conveniente elencar possíveis soluções de engenharia, a fim de amenizar os impactos ambientais no entorno dos parques, e melhorar o ambiente modificado por empreendimentos deste setor.Trabalho não financiado por agência de fomento, ou autofinanciad
Estratégia para dimensionamento otimizado de sistema de armazenamento por baterias para usina solar Padre Furusawa
Full text linkRenewable energy sources have been widely used around the world as an alternative for generating clean and sustainable energy. Among them, solar photovoltaic energy stands out as one of the most promising. However, the intermittency of this energy source poses a significant challenge, which can be mitigated through the use of energy storage systems. The proposed study in this thesis aims to develop an optimization program to calculate the ideal depth of discharge for the batteries in the storage system, which will be implemented in the Padre Furusawa Solar Plant. Based on non-linear and non-integer optimization, the program seeks to maximize the Net Present Value (NPV) of the project, considering the battery's lifespan and its financial impact on the investment. The results obtained with the optimization system validate the effectiveness of the proposed method, identifying an optimal depth of discharge of 96.58%, resulting in an NPV of R527.018,56 e uma Taxa Interna de Retorno (TIR) de 13%. A estratégia adotada apresentou melhorias significativas no desempenho e na rentabilidade do sistema de armazenamento, confirmando a importância da otimização dos parâmetros de operação, para projetos de usinas solares fotovoltaicas. Com a implementação da profundidade de descarga otimizada, obteve-se um ganho de 4,67% no VPL, reforçando assim a viabilidade e o impacto positivo da abordagem proposta
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
