Gestionando datos heterogéneos provenientes de sensores para medir la calidad del aire de Bogotá
Get PDFEl avance tecnológico y científico actual, ha impulsado el desarrollo de sistemas que mejoren la calidad de vida de las personas, aportando bienestar a la comunidad mediante el suministro de información relevante y pertinente para la toma de decisiones. En el contexto tecnológico de Internet de las Cosas (IoT), estos sistemas suponen la medición y el monitoreo de diversas variables del entorno. (Karnouskos, 2012) La heterogeneidad propia de los datos capturados y los instrumentos de medición utilizados, dificulta la interoperabilidad entre los diversos componentes de IoT. Tales problemas han generado interés en el desarrollo de métodos y herramientas que soporten la heterogeneidad de los datos de sensores, de las mediciones y de los dispositivos de medición. Existen herramientas privadas que han resuelto algunos de estos problemas de interoperabilidad pero restringen a los desarrolladores de proyectos IoT a utilizar sensores de marcas específicas, limitando el uso generalizado en la comunidad. Adicionalmente, se requiere resolver el reto de integrar protocolos diversos en un mismo proyecto IoT. Con el propósito de subsanar esas dificultades, se plantea una arquitectura basada en redes de sensores y software inspirados en la cultura libre, que permita la comunicación mediante protocolos diversos en un escenario de aplicación donde se monitorea la calidad del aire para informar a los usuarios, y que mediante la generación de alertas favorezca la toma de decisiones en su vida cotidiana, teniendo en cuenta los datos provenientes de los sensores.Abstract: The current technological and scientific progress has promoted the development of systems that improve people's quality of life, providing well-being to the community by the supply of relevant information for decision-making. In the technological context of the Internet of Things (IoT), these systems involve the measurement and monitoring of various environmental variables. The inherent heterogeneity of the captured data and the measurement instruments used makes it difficult to interoperate between the various IoT components. Such problems have generated interest in the development of methods and tools that support the heterogeneity of sensor data, measurements and measurement devices. There are private tools that have solved some of these interoperability issues but restrict IoT project developers to use proprietary sensors, limiting widespread use in the community. In addition, it is necessary to solve the challenge of integrating diverse protocols in the same IoT project. In order to overcome these difficulties, an architecture based on networks of sensors and software inspired by the free culture is proposed, allowing communication through various protocols in an application scenario where air quality is monitored to inform users, and that through the generation of alerts favor the decision making in their daily lives, taking into account the data coming from sensors.Maestrí
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

O sonho do engenheiro rebelde
No full textThis tale tells the story of an engineer who, despite his vast knowledge and skills in multiple fields, feels lost when he realizes that his creations contribute to the destruction of nature and social inequality. An encounter with a jaguar in a river makes him reflect on the possibility of a different kind of engineering, one that does not seek to dominate nature but to dialogue with it and take care of it. The jaguar advises him to unlearn and learn from the communities that live in harmony with the earth. The engineer decides to change his focus from being a builder of infrastructure to a caretaker of life, seeking balance between technology and nature. The story concludes with morals about the importance of questioning who benefits from our creations, collaborating with nature, and building solutions from the community.Este cuento narra la historia de un ingeniero que, pese a su vasto conocimiento y habilidades en múltiples campos, se siente perdido al darse cuenta de que sus creaciones contribuyen a la destrucción de la naturaleza y a la desigualdad social.

Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
