Perencanaan Jembatan Beton Prategang Dengan Bentang 24 Meter Berdasarkan Standar Nasional Indonesia (SNI)
Full text linkBridge is used to connect divided road sections, which are seperated by obstacles such as deep valley, river, lake, irigation canals, railway, and also grade seperated roadway. The construction of a bridge must comply with several requirements namely stiffness, deflection, and load bearing requirement. This research is a structural analysis and design of prestressed concrete girder beam with 24m length and 6.5m width. Working loads are dead load (MS), additional dead load (MA), vehicle load (TD), braking load (TB), pedestrian load (TP), and wind load (EW). Internal forces are obtained using Finite Element Method in SAP2000 nonlinear. Design of the bridge structure follows the national standar SNI 1725:2016 and RSNI T-12-2004. Result of structural design and analysis of the prestressed concrete girder beam uses 4 prestressed beam (160cm height, 1.83m distance between beam), 20cm bridge slab, and diaphragm with the dimension of 20x165x125cm . The number of tendon used in the design is 3, and each tendon comprises of 12 strand. The amount of prestressed force caused by jacking is Pj=5351.30 kN with loss prestress 24.52%. Deflection caused on the prestressed beam is dmaks = 12.6 mm (<dijin =80 mm), and occuring stress is 8696 kPa (< allowed stress 18675 kPa)
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
Pengujian Peningkatan Kapasitas Lentur dengan Penambahan Dimensi pada Sisi Bawah dan Atas Balok Beton Bertulang
Full text linkPengujian ini bertujuan untuk mengetahui besar peningkatan kapasitas lentur pada balok beton bertulang yang diperkuat dengan menambah dimensi balok pada sisi bawah dan sisi atasnya. Kami menggunakan 3 buah benda uji balok beton bertulang dengan dimensi 150 mm x 200 mm bentang 3000 mm. Benda uji pertama adalah tanpa perkuatan, yang kedua adalah diperkuat dengan menambah dimensi pada sisi bawah, dan yang ketiga adalah diperkuat dengan menambah dimensi pada sisi atas. Dengan penambahan dimensi sebesar 150 mm x 100 mm bentang 3000 mm, dimensi benda uji perkuatan menjadi 150 mm x 300 mm bentang 3000 mm. Pemberian beban untuk benda uji tanpa perkuatan dilakukan dengan jack hidraulic pada tengah bentang dan dibebani hingga benda uji runtuh. Sementara, untuk benda uji dengan perkuatan pemberian beban dilakukan dengan dua tahap. Hasil pengujian menunjukkan bahwa untuk benda uji dengan penambahan dimensi pada sisi bawah balok beton bertulang, kapasitas lentur meningkat sebesar 211,84 %. Sedangkan, untuk benda uji dengan penambahan dimensi pada sisi atas kapasitas lentur meningkat sebesar 192,98 % terhadap benda uji tanpa perkuatan. Berdasarkan peningkatan lentur tersebut dapat disimpulkan bahwa penambahan dimensi pada sisi bawah balok maupun pada sisi bawah balok beton bertulang aman untuk dilakukan
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
