ANALISIS METODE GAUSS-JORDAN DALAM PENENTUAN ARUS PADA RANGKAIAN LISTRIK
Get PDFPersamaan simultan sering dijumpai di bidang teknik termasuk pada bidang elektro khususnya pada rangkaian listrik. Salah satu metode untuk menentukan arus listrik dalam sebuah rangkaian listrik menggunakan metode Gauss-Jordan. Permasalahannya adalah berapa jumlah iterasi yang dibutuhkan oleh metode Gauss-Jordan dalam menyelesaikan sebuah persamaan simultan dari sebuah rangkain listrik. Tujuan penelitian ini selain menghitung nilai arus pada masing-masing loop sebuah rangkaian listrik, juga mengetahui banyaknya iterasi pada metode Gauss-Jordan dalam menyelesaikan sebuah persamaan simultan yang dihasilkan dari sebuah rangkaian listrik. Satu iterasi pada proses Gauss-Jordan yakni: normalisasi matriks kemudian dilanjutkan perkalian elemen matriks dengan persamaan ternomalisasi untuk menghasilkan matriks saat ini. Langkah selanjutnya adalah pengurangan element matriks dari sebelumnya dengan matriks saat ini untuk menghasilkan matriks selanjutnya. Acuan ini digunakan untuk menghitung jumlah iterasi dari metode Gauss-Jordan. Hasil proses metode Gauss Jordan menunjukan bahwa umlah iterasi Gauss-Jordan menyelesaikan persamaan simultan dengan model darai rangkain listrik sebanyak n iterasi. Dengan n adalah jumlah loop dari rangkaian listrik tersebut atau jumlah variabel dari persamaan simultan. Model persamaan simultan pada rangkaian listrik diperoleh dengan menerapkan Hukum Kirchof Tegangan dan Hukum Kircof Arus, diperoleh persamaan setiap loop pada rangkaian listri
Transformasi Pengelolaan Bank Sampah Melalui Pemanfaatan Teknologi Informasi: Peluang Ekonomi Baru
No full textKendala dalam mengelola sampah di masyarakat terus menjadi tantangan yang sulit diatasi. Terutama, masalah sampah plastik disebabkan oleh kurangnya pemahaman warga tentang tata kelola sampah. Salah satu solusi sederhana yang telah diterapkan adalah melalui pengembangan program bank sampah di Kecamatan Maulafa, Kota Kupang, Provinsi Nusa Tenggara Timur. Dalam pelaksanaan program ini, pendampingan mitra dilakukan mulai dari pembuatan situs web hingga promosi yang menarik di media sosial untuk Bank Sampah Mutiara Timor. Hasilnya menunjukkan kelancaran program dengan meningkatnya jumlah nasabah di Bank Sampah Mutiara, terutama melibatkan 120 generasi muda di Kota Kupang. Selain itu, pengabdian ini juga memperkaya sumber daya manusia di Bank Sampah dan mempermudah akses melalui situs web yang telah dibuat. Harapan ke depannya adalah agar kegiatan pengabdian ini dapat terus berlanjut, membantu mitra dalam menyebarkan sosialisasi, khususnya kepada ibu rumah tangga di Kota Kupang, untuk menabung sampah dan menghasilkan uang dari kegiatan tersebut
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
