Perancangan Dan Pembuatan Mesin Peniris Minyak Bagian Dinamis
No full textAlat ini menggunakan prinsip putaran, dengan mesin penggerak elektromotor. Mesin peniris minyak berfungsi untuk mengurangi kadar minyak pada bahan yang biasanya adalah gorengan. Mesin ini juga berfungsi mengurangi kadar air pada produk. Misalnya sayuran yang dicuci dan ingin cepat dikeringkan. maka dengan mesin spinner ini, kandungan air bisa cepat kering
Perancangan Dan Pembuatan Mesin Peniris Minyak (Bagian Dinamis)
No full textSetelah melihat permasalahan yang ada pada laboratorium mekanik Jurusan
Teknik Mesin Universitas Jember, dalam hal ini keterbatasan mesin poles yang
dapat di fungsikan untuk praktikum. Hanya ada satu mesin dengan 1 piringan
pemoles. Hal ini lah yang menjadi dasar pertimbangan kami untuk membuat
mesin poles dengan mengunakan dua piringan dan penambahan cekam spesimen
untuk alat bantu praktikum di laboratorium mekanik Universitas Jember.
Pembuatan rangka yang kuat sangat dibutuhkan untuk menahan beban
dinamis pada saat putaran rpm motor tinggi agar memberi kenyaman bagi
pengguna mesin poles uji mikro ini, juga dibuat rangka yang bias menahan
getaran motor agar alat ini tidak bergerak atau bergeser saat melakukan
pemolesan. Jadi dengan adanya mesin polishing ini, diharapkan mahasiswa
mampu memaksimalkan praktikum dengan sebaikbaiknya.
Cara kerja alat ini prinsipnya sama dengan alat elektronik, pertama-tama
disambungkan dengan sumber tegangan sebesaryang kemudian dengan
menggunakan transformator diturunkan tegangannya, sesuai dengan tegangan
yang dibutuhkan motor listrik. Selanjutnya motor AC berputar yang otomatis
menggerakkan dua piringan logam karena dihubungkan dengan menggunakan
puli dan belt. Kedua piringan logam ini dapat diatur kecepatan putarannya dengan
menggunakan rangkaian pengatur kecepatan motor listrik, terdapat 3 variasi
kecepatan yang dapat digunakan. Dengan menggunakan variasi kecepatan, dapat
dihasilkan sebuah proses pemolesan yang hasilnya dapat sesuai dengan
keinginan (Sawitri, 2011).
Alat poles uji mikro menggunakan double disk ini dapat menahan semua
beban dari komponen statis maupun komponen dinamis, dan untuk getaran alat ini
tidak mampu meredam getaran yang terjadi pada saat motor berjalan. Pada desain sambungan las pada rangka, pengelasan dari pengujian kedua terjadi retakan pada
rangka. Pada desain rangka, alat poles uji mikro ini sudah di desain dengan
penambahan disk poles dari yang sebelumnya yang menggunakan 1 disk poles,
penambahan 2 disk poles dapat mempercepat dalam pemolesan, dan juga
penambahan cekam spesimen yang berguna agar memberi kenyamanan dan
pengguna dapat lebih safety dalam penggunaannya
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
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
