di PT. Citra Sari Makmur. Penelitian ini menggunakan metode penelitian
kuantitatif. Populasi dalam penelitian adalah perangkat dari WiMaX dalam kondisi
Non Line Of Sight. sampel nya merupakan 4 Lokasi yang merupakan WiMAX Non
Line Of Sigh yaitu Jl. Jababeka IX C Blok D No. 5Q Kawasan Industri Jababeka,
Jl. Manimjau I No.11 Passa Wood, Jl. Pinus 2 No.17 Lt.2 Lippo Cikarang dan Jl.
Ki Hajar Dewantara Cikarang Utara.
Hasil dari penelitian ini yaitu Terdapat pengaruh jangkauan terhadap nilai RSL
dan nilai SNR, Ditunjukkan dengan besarnya koefisien korelasi jangkauan
terhadap RSL yaitu sebesar 0,85 dan besarnya koefisien korelasi jangkauan
terhadap SNR yaitu sebesar 0,63. Terdapat juga nilai lain yang mempengaruhi
baik buruk nya nilai RSL dan nilai SNR, yaitu tinggi antena penerima dubuktikan
dengan hasil korelasi nilai RSL sebesar 0,42 dan nilai korelasi SNR sebesar 0,65.
This study aims to determine the effect of WiMAX device coverage of Non Line
Of Sight to RSL and SNR values. This research was conducted at PT. Citra Sari
Makmur. This research uses quantitative research method. The population in the
study was the device of WiMaX under Non Line Of Sight condition. His sample
is 4 Locations which is WiMAX Non Line Of Sight ie Jl. Jababeka IX C Blok D
No. 5Q Kawasan Industri Jababeka, Jl. Manimjau I No.11 Passa Wood, Jl. Pinus 2
No.17 Lt.2 Lippo Cikarang dan Jl. Ki Hajar Dewantara Cikarang Utara.
Result of this research that is influence of range to RSL value and SNR value,
Shown by the magnitude of the correlation coefficient of the RSL range of 0.85
and the magnitude of the correlation coefficient of the SNR range of 0.63. There
are also other values that affect both the bad RSL value and the SNR value, ie the
receiver antenna height is dubukti with RSL value correlation value of 0.42 and
the correlation value of SNR of 0.65
Penyiraman Tanaman Otomatis Berbasis IoT Menggunakan Node MCU ESP8266
Full text linkPenyiraman tanaman harus dilakukan dengan tepat waktu karena hal tersebut dapat mendukung pertumbuhan tanaman secara optimal. Maka dibutuhkan suatu penerapan sistem yang dapat mengatur penyiraman tanaman dalam kondisi yang tepat dan juga bisa meminimalisir kerja manusia. Dengan latar belakang ini maka peneliti akan membuat sebuah alat penyiram tanaman otomatis berbasis IoT. Tujuan pembuatan alat ini adalah untuk memudahkan pekerjaan manusia dalam hal penyiramaan tanaman agar manusia tidak tidak perlu lagi menyiram tanaman secara manual setiap harinya. Metode Research and Development (R&D) di terapkan dalam penelitian ini. Adapun tahapan dari metode RAD meliputi : Requirement Planning, Design Workshop, Fase Instruction, Implementation. Untuk mengetahui hasil dari penelitian yang telah dilakukan, maka peneliti melakukan pengujian terhadap seluruh kriteria pengujian. Berdasarkan hasil pengujian pada alat penyiraman tanaman otomatis berbasis IoT dapat disimpulkan bahwa alat tersebut dapat bekerja sesuai dengan perancangan yang telah dirancang. Kelembapan tanah sesuai dengan ketentuan kondisi yang sudah di tetapkan kemudian relay memberikan aksi kerja sesuai dengan kondisi kelembapan tanah sehingga pompa dapat bejalan sesuai dengan kondisi tanah serta LCD dan aplikasi blynk dapat menampilkan tingkat kelembapan tanah sesuai dari data yang didapat dari sensor
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
