A Study and Design of Flexible Planar Antenna with Different Substrates for Long-Range Applications
No full textIn the past few years, there has been a huge rise in the need for flexible antennas, especially in the field of body area networks (BANs) or telemetry. The article proposed the performance analysis of different substrates used to design flexible antennas. For this analysis, the antenna is designed using the basic microstrip patch formula with the commonly used substrate FR-4 with a dielectric constant of 4.4. Then, the patch antenna is designed using different flexible materials, and their performance is studied and compared. For one comparison table, the dimension is compared for each substrate using the microstrip patch formula, keeping the LoRa frequency of 868 MHz as a reference. And, for the next comparison, the dimension is kept constant while the substrate is varied, and the results are compared and represented in graphs. From this article, the researcher will get help in selecting the flexible substrate for wearable antenna and the application depending on the size and performance of the transceiver system.</p
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
A Review: Emerging Trends of Big Data in Higher Educational Institutions
No full textUniversities/higher educational institutions are finding ways to increase the student-faculty interactions beyond the traditional classroom, helping institutions to gather the information to enhance the student learning experiences with the help of learning analytics. These interactions are captured using the virtual learning environment through which institutions learn from the student interactions and behavioral patterns within those systems. This helps the institutions for better retention rate, prediction of the results and focus on weak students. Many institutions have placed an early detection system for management and faculty to engage with the students and figure out the problems faced by the students and provide a remedy to improvise for the faculty members. Most of the institutions rely mainly on one system such as the learning management system to capture the student interactions thus creating a gap. The Internet gives an edge to its users for practicing, learning, by doing, this leads to the emergence of video-based learning technologies that are practiced and used in several ways, such as flipped classrooms. Student faces a doubt often in their phase of learning, to clear their doubts they refer to multiple sources to get the information and knowledge. These videos provide complete skill sets, students due to lack of skill set they use these sources for their specific problems. This paper discusses literature and background studies on the big data used in institutions of higher education. It establishes a framework based on the latest trends in this area that can help stakeholders to predict their business needs
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
