Pengembangan Alat Pembuat Peta Konsentrasi Gas, Suhu, dan Kelembaban pada Pesawat Tanpa Awak
Get PDFAlat pembuat peta konsentrasi gas, suhu dan kelembaban adalah sebuah alat yang dirancang untuk memetakan kondisi gas pada suatu wilayah. Alat ini bekerja dengan diletakkan pada pesawat tanpa awak dan diterbangkan pada ketinggian tertentu untuk mendapatkan data kondisi gas, suhu dan kelembaban. Saat ini pemantauan kondisi gas hanya berada pada daerah-daerah tertentu dan dalam jangkauan yang kecil. Sumber gas karbon monoksida dan metana sudah begitu banyak. Pembakaran sampah, kebakaran hutan, kendaraan bermotor hingga letusan gunung merapi mengeluarkan gas karbon monoksida dan metana dengan volume yang tinggi. Sumber-sumber gas alam yang baru muncul juga tidak dapat diprediksi persebarannya. Akhirnya alat pembuat peta konsentrasi gas, suhu dan kelembaban akan diterbangkan pada daerah yang mengandung konsentrasi gas beracun yang tinggi. Alat ini bekerja dengan menggunakan mikroprosesor ATmega 2560. Dilengkapi GPS untuk menentukan lokasi dengan kondisi gas tertentu. Sensor suhu dan kelembaban juga dimaksudkan untuk memantau kondisi udara pada wilayah tersebut. Data hasil pengukuran akan disimpan pada kartu memori yang terpasang pada alat tersebut menggunakan metode data logger dan akan diproses pada perangkat komputer secara offline. Peta konsentrasi gas, suhu dan kelembaban dibuat dengan metode K Nearest Regressor.
Alat yang dirancang sudah berhasil dibuat dengan ukuran 6.5 cm x 5 cm x 2 cm dan dipasang pada UAV. Pengujian yang telah dilakukan yakni pada Pakuwon City Kejawan Tambak. Peta yang dihasilkan berbentuk 3D maupun 2D dengan warna yang disesuaikan tingkat konsentrasi gas, suhu, dan kelembaban.

Gas concentration, temperature and humidity map maker are a device designed to map gas conditions in an area. This tool works by being placed on unmanned aircraft and flown at a certain height to obtain data on gas conditions, temperature and humidity. At present the monitoring of gas conditions is only in certain areas and in a small range. The source of carbon monoxide and methane is already so much. Garbage combustion, forest fires, motor vehicles to the eruption of volcano emit high volumes of carbon monoxide and methane. The new sources of natural gas are also unpredictable. Finally, the gas concentration, temperature and humidity map maker will be flown in areas containing high concentrations of toxic gases. This tool works by using an ATmega 2560 microprocessor. Equipped with GPS to determine the location with certain gas conditions. Temperature and humidity sensors are also intended to monitor air conditions in the area. The measurement data will be stored on the memory card installed on the device using the data logger method and will be processed on a computer device offline. Map of gas concentration, temperature and humidity is made by the K Nearest Regressor method.
The tool designed has been successfully made with a size of 6.5 cm x 5 cm x 2 cm and installed on a UAV. Tests that have been done are Pakuwon City Kejawan Tambak. The resulting map is in the form of 3D and 2D with colors that are adjusted for gas concentration, temperature, and humidity levels
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
