PROST : a framework for the development of programmable devices for IoT
Full text linkOrientadores: Edson Borin, Juliana Freitag BorinDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: Incontáveis tipos de dispositivos embarcados conectados à internet compõem a chamada Internet das Coisas, a qual promoverá a geração de um fluxo massivo de dados e o controle dos dispositivos, muitas vezes, de forma centralizada. Entretanto, as soluções existentes para este tipo de cenário estão sujeitas a falhas de conexão e requerem elementos externos para o monitoramento e controle dos dispositivos. A fim de mitigar essas limitações, este trabalho propõe uma plataforma para execução de código de usuário como serviço em dispositivos da Internet das Coisas. O principal objetivo da solução apresentada é permitir a execução de código como serviço em qualquer dispositivo conectado na internet e promover a interação transparente entre dispositivos. Algumas vantagens dessa abordagem são a capacidade de evitar a propagação de dados não essenciais na rede, a possibilidade de controlar dispositivos internamente e a compatibilidade com dispositivos computacionalmente restritos. O arcabouço PROWL(PROgrammable Smart Things) proposto combina: (I) um protocolo de comunicação referência para descoberta e descrição de dispositivos conectados em uma rede de computadores e (II) uma plataforma compacta que executa aplicações compiladas para uma arquitetura de fácil emulação. Finalmente, para validação da plataforma projetada, são apresentados estudos de caso em diferentes cenários, corroborando a eficácia da soluçãoAbstract: Innumerable types of embedded devices connected to the internet make up the so-called Internet of Things, which will promote the generation of a massive flow of data and the control of the devices, often centrally. However, the existing solutions for this type of scenario are subject to connection failures and require external elements for the monitoring and control of the devices. In order to mitigate these limitations, this work proposes a platform for executing user code as a service in devices of the Internet of Things. The main goal of the presented solution is to enable the execution of code as a service on any device connected to the Internet and to promote transparent interaction between devices. Some advantages of this approach are the ability to avoid spreading nonessential data on the network, the ability to control devices internally, and compatibility with computationally constrained devices. The proposed PROgrammable Smart Things framework combines: (I) a reference communication protocol for discovery and description of connected devices in a computer network and (ii) a compact platform that runs compiled applications for an easy-to-emulate architecture. Finally, to validate the projected platform, case studies are presented in different scenarios, corroborating the effectiveness of the solutionMestradoCiência da ComputaçãoMestre em Ciência da Computação132788/2015-2CNP
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
