ENERGY AND ARCHITECTURAL RETROFITTING IN THE URBAN CONTEXT OF ATHENS
No full textThe aim of this paper is to study, evaluate and demonstrate the technical feasibility
of nearly zero energy buildings the Athens’ urban context. To achieve this purpose, the energy
performance of selected typical residential buildings in the urban Athens area have been
investigated, in order to properly identify the buildings’ energy requirement in winter and
summer conditions and finally propose targeted retrofitting hypothesis towards nearly Zero
Energy Buildings (nZEBs). The study has been developed on the real case study of a social
housing compound of the '60s, with typical structures built by reinforced concrete and infill
walls. The setting is located in Peristeri suburbs, in the western Athens Metropolitan Area,
which, together with the central Athens, present the highest heat island (HI) intensity of the
whole city. Focusing on urban areas, the proposed research considers the buildings and the
related space as a whole
Climate Oriented Urban Design. Thermal comfort in urban spaces and energy saving potential in built environments
Get PDFThe volumetric configuration of the urban textures and the materials that constitute the external
surfaces, are the main factors that influence the microclimate of a city. Comprehend and being
able to transform in an adequate way the urban settings could contribute to the improvement of
the thermal comfort in outdoor and indoor built environments. By using as a principal indicator
thermal comfort the variation of the external temperatures in an unprecedented collaboration
between different scales and different environmental simulation systems, this paper analyses
the energy saving potential given by the use of green and passive techniques and shows the
synergies that may arise between outdoor and indoor spaces
New strategies towards nearly zero energy in existing buildings: the ABRACADABRA project.
Get PDFABRACADABRA is an European Project funded by the Horizon 2020 Program, based on the assumption that substantial
increase in the real estate value of the existing buildings can play a key role in the deep renovation. The project aims at
demonstrating to the key stakeholders and financial investors the attractiveness of a new renovation strategy based on volumetric
Abstract
Add-ons and Renewable energy sources (AdoRES) intended as one (or a set of) Assistant Building unit(s) – like aside or façade

District heating networks are commonly addressed in the literature as one of the most effective solutions for decreasing the Buildings) to achieve nearly zero energy. The creation of these AdoRES aims at reducing the initial investment allocated for the
greenhouse gas emissions from the building sector. These systems require high investments which are returned through the heat deep renovation of the existing building creating an up-grading synergy between old and new. The ABRA strategy can thus result

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
