The first Italian Renewable Energy Community of Magliano Alpi
No full textThe first Italian renewable energy community, in which the municipality, citizens, and local utilities will produce and exchange energy from renewable sources, has been realized in the town of Magliano Alpi. The energy community was established according to the new regulation of Law 8/2020 and the Italian electricity regulator ARERA, which allows the creation of new renewable energy communities strongly integrated at the urban or small district level. The paper describes the main technical and economic characteristics of this energy community, illustrating the Italian legislation, the technologies used for the electricity measurement management of energy exchanges, and the economic benefits to the energy community participants provided by the current regulation
Dynamic Programming for Optimal Energy Management in Nanogrids
No full textThe technological advancement in the energy sector leads to innovative grid structures for increasing the connection of renewable energy sources. The Nanogrid, a local modest-sized building energy system with power generation, energy storage, and real-time operation system, ranging from a residential home to a small commercial or industrial building, is a typical example. This paper aims to analyse the benefits for prosumers derived by adopting an intelligent electric energy management system that enables the optimal coordinated operation of the available resources within their Nanogrid. The optimisation objective is to maximise profits for the smart Nanogrid owner. The proposed energy management system is based on a dynamic programming algorithm implemented in MatLab on which is modelled the control system of the Nanogrid. The simulation result confirms that the proposed approach can be used in e realistic real-world case study
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
Multi-Energy Smart City Urban District Planning with Robust Optimisation
No full textOver the years, different energy systems have often been planned and managed independently and not always efficient and optimised. A paradigm shift towards a holistic, multi-generation approach can achieve more significant benefits by integrating the energy infrastructure for electricity, natural gas and district heating networks and creating energy hubs in the urban districts of future smart cities. In such systems, different energy carriers interact collaboratively. The number of uncertainties in multi-energy hubs requires developing optimisation planning methodologies capable of keeping the risk below acceptable values. In this context, the paper proposes a robust linear programming optimisation algorithm to solve the energy hub planning problem under uncertainty. The optimisation algorithm allows the identification of the optimal energy carriers to meet energy demands and minimise energy costs keeping the risk of failure below the allowable level. Simulation results highlight the benefits of applying the proposed approach considering a multi-energy hub structure in an urban district of the city of Cagliari (Italy)
