No full textThe highway is one of the land transportation infrastructure that serves to connect one area to another for public activities such as economics and social activities. Safe, comfortable, and efficient roads are not avoided by the availability of a flat road and no significant road damage.This research to calculate the life cycle cost analysis of the road with the calculation of pavement thickness that has been done by Ramadhani (2017). The method used in this research is by study case method, by collecting data about Janti-Prambanan Road section KM 7 + 750-8 + 750 and analyzing life cycle cost by estimating road maintenance that will be done during the life of the plan.Based on the analysis that has been done, the cost of construction or initial cost that must be issued based on the thickness of pavement set by Ramadhani (2017) with the total thickness of paved layer 50 cm is Rp. 14,089,007,000. The cost of maintenance at Alternative1 is Rp. 2.565.778.485,91 and at Alternative2 is Rp. 2,555,861,411.86. The total cost of the road life cycle in Alternative 1 is Rp. 16.654.785.485,91 while at Alternative 2 of Rp. 16,644,868,411.86. Analysis of the lifecycle cost of the two alternatives found EUAC for Alternative 1 is Rp. 65,649.89, while for Alternative 2 is Rp. 65,610.80. So that can be said by advancing the rehabilitation at least save on maintenance costs.One infrastructure in the field of transportation is the highway. The highway is one of the land transportation infrastructure that serves to connect one area to another for public activities such as economics and social activities. Along with the increasing number of population in Indonesia, especially in D.I. Yogyakarta, therefore, requires safe, comfortable and efficient road conditions to support the economic needs of the community. Safe, comfortable and efficient roads are not avoided by the availability of a flat road and no significant road damage. This research proceeds from Ramadhani’s (2017) research to calculate the life cycle cost analysis of the road with the calculation of pavement thickness that has been done by Ramadhani (2017).

Full text linkJaringan syaraf tiruan merupakan bagian dari ilmu kecerdasan buatan, Jaringan syaraf tiruan memiliki proses kerja sama dengan cara kerja otak manusia. Proses pengenalan pola dengan cara melihat nilai input apakah sama hasilnya dengan nilai output sehingga pola tersebut bisa dikenali oleh sistem itu sendiri. Penelitian ini menggunakan metode Bidirectional Associative Memory (BAM) memiliki kemampuan sebagai associative memory atau content addressable memoryi yaitu memori yang dapat dipanggil menggunakan bagian dari informasi yang tersimpan di dalamnya. Metode Bidirectional Associative Memory (BAM) memiliki 2 lapisan dan terhubung penuh dari satu lapisan ke lapisan yang lainnya, sehingga dimungkinkan adanya hubungan timbal balik antara lapisan input dan lapisan output. Konsep algoritma bersifat bidirectional dimana bobot sinyal akan dikirim dari lapisan Input X ke lapisan output Y . Bobot akan dirobah menjadi nilai yang lebih halus dengan ketentuan hasil antara rang [1,0]. Fungsi yang digunakan dalam penelitian ini yaitu fungsi aktifasi sigmoid. Hasil pengenalan pola huruf dari penelitian ini menggunakan system Matrik ordo 5x5 dengan inputan 3 Karakter yaitu karakter huruf S, O dan huruf X. Target Huruf S [1,-1] menghasilkan pola [27 4] sesuai dengan target, Pola huruf O [1.1] menghasilkan pola [27 -3] tidak sesuai dengan target dan huruf X [-1,1] menghasilkan pola [-37 21] sesuai dengan target. Dengan demikian tidak semua pola bisa memperoleh target yang sudah ditentukan

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
