Mobility-enabled networking scheme for rich media Internet of Things platforms
Full text linkThis thesis proposes and evaluates an Internet of Things (IoT) solution consisting of architectures and algorithms, which enable several heterogeneous devices to intercommunicate, providing support for their offered services. An IoT network needs to enable exchange of diverse data types including rich-media and sensor data and handle a large number of devices, offering services at high quality levels. These goals are achieved by innovative solutions, which improve the performance and quality of IoT services and allow exchange of rich-media content. The proposed architecture consists of IoT objects and their services, smart gateways, supporting IoT object network connectivity, and cloud platforms employed for resource management. The performance and quality of IoT services are improved through NETSMITS
(NETworking Scheme for sMart IoT gatewayS), which contains an algorithm that uses Quality of Service (QoS) and service relevance metrics in order to efficiently cluster inter-communicating IoT objects, attach them to the most suitable smart gateway and
improve the performance of their services. The IoT mobility challenges are addressed through REMOS-IoT (RElay and MObility Scheme for the Internet of Things), which introduces algorithms that use QoS and service relevance metrics, age of information, and objects location in order to provide the best connectivity for devices and achieve better overall performance and QoS. A higher layer in the architecture contains VRITESS (VR-IoT Environment Synchronisation Scheme), which allows virtualisation of the IoT devices to fulfil requirements of certain rich-media devices and platforms, such as virtual reality (VR) devices and social media, integrating them to the IoT network.
The contributions presented in this thesis include simulation models and testbeds for the mobility-enabled networking scheme for rich-media IoT, demonstrating performance improvements in comparison with other baseline solutions. A survey of IoT
architectures, applications, QoS, protocols and mobility solutions is also provided
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
REMOS-IoT - A Relay and Mobility Scheme for Improved IoT Communication Performance
Full text linkThe Internet of Things (IoT) can avail from device-to-device (D2D) communication techniques to increase object data exchange performance. IoT networks aim to offer a massive number of services at high quality levels, and many of the devices providing these services are mobile. Devices such as wearables, sensors, drones and smart vehicles need constant connectivity despite their moving patterns and therefore, an IoT architecture should consider both Quality of Service (QoS) and mobility. D2D allows devices to communicate directly to share content and functionality, such as access to the Internet. This paper proposes REMOS-IoT - A RElay and MObility Scheme for improved IoT communication performance in support of increased QoS for the data exchange services between mobile IoT devices. Simulation-based testing showed how performance of devices increased in several scenarios, demonstrating the efficiency of the proposed architecture and algorithms
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
