PENDEKATAN PARAMETER FUNGSI SINUSOIDAL MENGGUNAKAN TRANSFORMASI FOURIER DALAM OPTIMASI ALGORITMA LEAST SQUART NONLINIER
No full textDalam penyelesaian algoritma least squart nonlinier, khususnya fungsi sinusoidal, penentuan kondisi inisial parameter sangat sensitif dalam menghasilkan model optimal, penyebabnya adalah banyaknya nilai minima yaitu antara hingga . Penelitian ini melakukan pendekatan kondisi inisial parameter ke nilai parameter optimal. Dasar pemikirannya adalah mencari frekuensi-frekuensi domain yang terdapat pada fungsi sinusoidal sesuai banyaknya suku yang dimilikinya. Transformasi Fourier digunakan untuk mencari frekuensi domain tersebut dan kemudian digunakan sebagai kondisi awal. Penelitian ini berhasil membuat algoritma menjadi lebih efesien dan menurunkan rasio error selama iterasi berjalan
Tinjauan Sifat Invarian Medan Skalar Bermassa Dan Medan Maxwell Kovarian Terhadap Transformasi Tera
No full textTelah dilakukan peninjauan ulang sifat invarian interaksi antara medan skalar bermassa dengan medan Maxwell kovarian terhadap transformasi tera jenis pertama dan kedua. Penelusuran teori tentang medan Klein-Gordon yang ditransformasikan ke dalam transformasi tera memberikan pilihan untuk menggunakan medan skalara kompleks yang invarian terhadap transformasi tera yang kemudian diinteraksikan dengan medan Maxwell kovarian. Dengan menggunakan persamaan Euler-Lagrange akan menghasilkan persamaan kekekalan rapat muatan dan rapat aru
MODEL NON LINEAR KEJADIAN CURAH HUJAN EKSTRIM DI KOTA PALU MENGGUNAKAN PROGRAM JAVA
No full textWeather and climate are the main factors for influence on various activities of life. The increasing of human activity has made the change in components biophisical environment, which are major contributors about climate change. The most important of the process of climate change is the emergence of the extreme, that one example is, extreme rainfall, that the rainfall have more than 50 mm intensity / day. To know characteristic of climate change occurring, needed a model who represented data rainfall in various meteorology station. Based on it, author make a modeling the extreme rainfall in Palu city using Java programming. The results of the extreme rainfall predictions 10 years using software models and Java programming, in Palu city with using fourier series function order 5 predicted the extreme rainfall will likely increase every year with the highest event are 2 times / years. The prediction was featuring the precisely value with the real data. So, we can conclude that the extreme rainfall model tends to be accurate and can be used to predict the extreme rainfall in Palu city and in other cities
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
