No full textAgriculture is an important economic activity in our country, since it provides employment for thousands of people and contributes significantly to the national GDP. According to a report by Jiménez in 2020, agriculture contributed 9.1% of GDP in 2019. In addition, the agricultural sector generates around 11% of employment in the country, according to an article in the digital newspaper “El Guardian”. However, agriculture also faces challenges, especially during the dry season, when plantations can be lost if not adequately irrigated. Therefore, in this Project, an automated irrigation system is proposed to help farmers irrigate their crops more efficiently. This irrigation system will use sprinklers, temperatura, humidity sensors, and a PLC to automatically control irrigation. The Project aims to help farmers who need it most by improving irrigation efficiency. If implemented correctly, the automated irrigation system can help reduce crop losses during the dry season, increasing crop production and yield. This, in turn, can contribute to the national economy by creating more employment and increasing agricultural production. In short, this project aims to improve agriculture in the country and increase its contribution to economic development.La agricultura es una actividad económica importante en nuestro país, ya que proporciona empleo a miles de personas y contribuye significativamente al PIB nacional. Según un informe de Jiménez en 2020, la agricultura contribuyó con el 9,1% del PIB en 2019. Además, el sector agropecuario genera alrededor del 11% del empleo en el país, según un artículo del periódico digital “El Guardián”. Sin embargo, la agricultura también enfrenta desafíos, especialmente durante la época seca, cuando las plantaciones pueden perderse si no se riegan adecuadamente. Por lo tanto, en este proyecto se propone un sistema de riego automatizado que ayudará a los agricultores a regar sus cultivos de manera más eficiente. Este sistema de riego utilizará aspersores, sensores de temperatura y humedad, y un PLC para controlar el riego de forma automática. El objetivo del proyecto es proponer un sistema de riego automatizado con el fin de ayudar a los agricultores que más lo necesitan al mejorar la eficiencia del riego. Si se implementa correctamente, el sistema de riego automatizado puede ayudar a reducir las pérdidas de cultivos durante la temporada seca, aumentando la producción y el rendimiento de los cultivos. Esto, a su vez, puede contribuir a la economía nacional al generar más empleo y aumentar la producción agrícola. En resumen, este proyecto tiene como objetivo mejorar la agricultura en el país y aumentar su contribución al desarrollo económic
Educación STEM a través del modelado e implementación de impresión 3D dentro de las áreas biomédica e industrial
No full text3D modeling and printing is a widely used technology. It can be used in different areas of the industry such as to print electronic devices such as sensors and electronic boards, implementations within the biomedical area to manufacture prostheses and parts of the human body for surgical preparation, or even within industries such as aeronautics and automotive. All of these applications and their importance within our society require us to place greater emphasis on the areas of stem education that involve these technologies. That is why it is considered vitally important to teach this relevant technology to young and creative people, who are still not sure which way to go in their university life, a workshop on these technologies can give them that boost they need to be able to take a decision and be motivated to innovate by creating designs in 3D modeling software and then prototyping in both software and 3D printingEl modelado e impresión 3D es una tecnología ampliamente utilizada. Puede ser utilizado en diferentes áreas de la industria como para imprimir dispositivos electrónicos como sensores y placas electrónicas, implementaciones dentro del área biomédica para fabricar prótesis y partes del cuerpo humano para preparación quirúrgica, o incluso dentro de industrias por ejemplo aeronáutica y automotriz. Todas estas aplicaciones y su importancia dentro de nuestra sociedad nos hacen requerir un mayor énfasis en las áreas de educación de tallos que involucran estas tecnologías. Por ello es que se considera que es de vital importancia enseñar esta relevante tecnología a personas jóvenes y creativas, que aún no están seguras de que camino tomar en su vida universitaria, un taller sobre estas tecnologías puede darle ese impulso que les falta para poder tomar una decisión y motivarse a innovar mediante la creación de diseños en modelado 3D por software y luego prototipar tanto en software como en impresión 3

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
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
