An Energy-Efficient Content-Centric Approach in Mesh Networking
No full textContent-centric is an emerging networking paradigm conceived for the future Internet. Data retrieval and distribution are based on content names instead of host addresses. In this paper we propose a content-centric architecture for energy- efficient multihop communications in a wireless mesh network and compare its performances against a legacy IP-based ap- proach
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
Enabling Social Digital Twins in the 6G Era with Information Centric Networking
Full text linkBy creating the virtual representation of the elements and services of physical systems, Digital Twins (DTs) are expected to provide crucial support to the ambitious Sixth-generation (6G) applications. Being data-driven entities that process a variety of data in real-Time, DTs can be hosted at the network edge, thus providing low latency services. However, the deployment of a networking architecture supporting the dynamic discovery of DTs and their instantiation at the edge is still an open challenge. To fill the gap, in this article we conceive a solution that leverages two revolutionary paradigms, namely the Social Internet of Things (SIoT) and Information Centric Networking (ICN). On the one hand, SIoT can provide trustworthy interactions between DTs to support effective service discovery and composition. On the other hand, ICN is a network model that includes data-centric primitives and in-network caching to facilitate service provisioning. By combining the two paradigms, we create a new framework where DT services are requested by name and discovered in a timely fashion by navigating a name-based SIoT network. Whenever possible, services already instantiated at the edge are reused to satisfy different clients. After demonstrating the benefits of the envisioned framework with a preliminary evaluation, we highlight research opportunities for this timely topic
Composing Digital Twins for Internet of Everything Applications: A User-Centric Perspective
No full textDriven by the advancements in Artificial Intelligence (AI) and cutting-edge communication technologies, the interest in Digital Twins (DTs) has grown in recent years. Today, DTs are investigated in a variety of Internet of Everything (IoE) use cases, thanks to their capability to optimize and predict the behaviour of their physical counterpart. Several application-driven vertical architectures have been proposed for DTs, but a general-purpose modeling approach is lacking. Although the research community is promoting holistic DT representations, practical software deployments of complex physical entities will be likely achieved through multiple interconnected DTs that together provide composite advanced services. In this paper, we present a user-centric architecture to deploy DTs in a flexible, dynamic, and reusable fashion, according to the requirements of the user applications. In our vision, complex DTs can be composed by integrating digital replicas (DRs) of physical objects with an AI-driven Service Layer. DRs are implemented as representation models collecting real-time data from the physical counterpart and therefore enabling vertical intra-twin communications. In parallel, a Service Layer allows to share knowledge and services among DTs through horizontal inter-twin communications, i.e., between DTs in the virtual space, which can be exploited to anticipate users’ needs. A toy example is presented to showcase the conceived architecture
