ECCAuth: A Secure Authentication Protocol for Demand Response Management in a Smart Grid System
No full textThe devices in smart grids (SG) transfer data to a utility center (UC) or to the remote control centers. Using these data, the energy balance is maintained between consumers and the grid. However, this flow of data may be tampered by the intruders, which may result in energy imbalance. Thus, a robust authentication protocol, which supports dynamic SG device validation and UC addition, both in the local and global domains, is an essential requirement. For this reason, ECCAuth: A novel elliptic curve cryptography-based authentication protocol is proposed in this paper for preserving demand response in SG. This protocol allows establishment of a secret session key between an SG device and a UC after mutual authentication. Using this key, they can securely communicate for exchanging the sensitive information. The formal security analysis, informal security analysis, and formal security verification show that ECCAuth can withstand several known attacks
Preface
No full textThe 2nd International Conference on Blockchain and Applications 2020
(BLOCKCHAIN’20), held in the Heritage city of L’Aquila (Italy), has been a
meeting point for both experienced and young researchers investigating in the areas
of blockchain and artificial intelligence (AI). The conference has acted as a forum at
which the attendees listened to lectures, and shared and discussed ideas, projects
and advances associated with these technologies and their application domains.
Within the scientific community, blockchain and AI are viewed as a promising
combination that will transform the production and manufacturing industry, media,
finance, insurance, e-government, etc. Nevertheless, there is no consensus with
schemes or best practices that would specify how blockchain and AI should be used
together. Combining blockchain mechanisms and artificial intelligence is still a
particularly challenging task, and the BLOCKCHAIN’20 conference has been a
milestone towards its achievement.
The BLOCKCHAIN’20 conference has been devoted to promoting the investigation of cutting-edge blockchain technology, exploring the latest blockchain- and
AI-related ideas, innovations, guidelines, theories, models, technologies, applications and tools for the industry. Critical issues and challenges have been identified
so that researchers and practitioners may address them in future research. The
technical programme has been carefully designed to offer a fresh and balanced
selection of advances and results in blockchain and AI, encouraging focus on novel
and interdisciplinary topics.
The technical programme has been diverse and of high quality, and it focused on
contributions to both well-established and evolving areas of research. More than 40
papers have been submitted to 20 from over 20 different countries (Canada, France,
Germany, India, Ireland, Italy, Jordan, Luxembourg, Malaysia, Malta, Morocco,
Netherlands, Oman, Portugal, Slovenia, Spain, Sweden, UAE and USA).
We would like to thank all the contributing authors, the members of the
Programme Committee, the sponsors (IBM, Indra, EurAI, AEPIA, AFIA, APPIA
and AIR Institute) and the Organizing Committee for their hard and highly valuable
work. We thank the funding supporting with the project “Intelligent and sustainable mobility supported by multi-agent systems and edge computing” (Id.
RTI2018-095390-B-C32); their work contributed to the success of the
BLOCKCHAIN’20 event, and finally, we thank the Local Organization members
and the Programme Committee members for their hard work, which was essential
for the success of BLOCKCHAIN’20
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
