Smart Grid projects in Europe:Lessons learned and current developments 2012 update
No full textSmart Grid projects play a key role in shedding some light on how to move forward in this challenging transition. To this end, in 2011, the JRC launched the first comprehensive inventory of Smart Gird projects in Europe to collect lessons learned and assess current developments on Smart Grids in Europe [JRC 2011].
The final catalogue was published in July 2011 and included 219 Smart Grid and smart metering projects from EU27 Member States (including 24 smart metering pilots and roll-outs). The overall investment amounted to € 5 billion.
The participation of project coordinators and the reception of the report by the Smart Grid community were extremely positive. For this reason, it has been decided to carry out the project inventory on a regular basis to constantly update the picture of Smart Grid developments in Europe and keep track of lessons learned, challenges and opportunities.
This study is the 2012 update of the inventory carried out in 2011.
A new on-line questionnaire was put on-line in March 2012 and projects were collected until September 2012. In parallel we have performed an extensive and scrupulous search of projects information through web research and cooperation links with European research organizations.
The resulting final database is the most updated and comprehensive inventory of Smart grid and smart metering projects in Europe for 2012: it includes 281 Smart Grid projects and around 90 smart metering pilots and roll-outs. Smart Grid and smart metering projects will be analysed separately.
The core of our analysis will focus on Smart Grid projects. Smart metering development will be analysed only at aggregated national and European level and information from individual smart metering projects will be used only to support the analysis with concrete field information .JRC.F.3 - Energy securit
Project H-22: Synthesis and HYDROGEN SORPTION characterisation of magnesium-rich compounds with transition metals
No full textOur research activities during 2007 were focused on the synthesis of new Mg-rich alloys, and on their characterization in relation to their crystal structure and macroscopic hydrogen sorption properties. The collaboration made use of the synthesis and crystallographic characterization facilities at the Uppsala University and of the hydrogen sorption instruments and microstructural analysis services at JRC. The preparation of the starting materials and their thorough crystallographic characterization were performed at the Uppsala University. The kinetic of desorption, cycling properties and microstructural analysis were performed in the Joint Research Centre.JRC.F.2 - Cleaner energ
Project H-22: Synthesis and Hydrogen Sorption Characterisation of Magnesium-Rich Compounds with Transition Metals
No full textThe main focus of our efforts in 2008, under this IEA HIA Task 22 project, was the investigation of new ternary compounds in the Y-Mg-Ga and Mg-Y-Ti systems. The research activity included synthesis of the compounds, and subsequently micro- and macro-scopic characterizations, making use of the material production and crystallographic characterisation facilities at the Uppsala University and of the hydrogen sorption instruments and microstructural analysis services at JRC.JRC.F.2 - Cleaner energ

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
