ANALISA MULTI HOP ROUTING PADA WIRELESS SENSOR NETWORK DIGITAL
Full text linkPerkembangan teknologi wireless sensor network digital saat ini sedemikian pesat, jaringan sensor ini semakin luas aplikasinya di berbagai bidang kehidupan, seperti di bidang lingkungan, kesehatan, otomotif, rumah, militer, dan lain sebagainya.Terlebih dengan semakin banyaknya aplikasi berbasis cloud dan pemanfaatan konsep Internet of Things (IoT) sehingga sensor digital ini mampu mentransfer data tanpa perlu terhubung dengan manusia, tetapi menggunakan internet sebagai medianya. Titik-titik sensor digital yang berbasis wireless ini saling berkomunikasi satu sama lainnya sehingga membentuk jaringan.Setiap titik sensor menggunakan protokol untuk dapat saling berkomunikasi, protokol tersebut terdiri dari lapisan aplikasi, lapisan transport, lapisan jaringan, lapisan data link, lapisan fisik dan protokol lintas-lapisan.Komunikasi wireless ini hanya terjadi apabila terdapat link antara sensor dengan access point atau base station. dalam konsep multi hop wireless ini ditempatkan satu atau lebih access point diantara sepanjang jalur link yang berfungsi untuk menerima dam meneruskan paket data melalui link wireless. Jaringan multi hop ini memiliki beberapa manfaat diantaranya dapat memperluas jangkauan jaringan dan meningkatkan konektivitas. Dalam penelitian ini akan dilakukan analisa mengenai aspek-aspek multi hop routing pada wireless sensor network digital sehingga dapat dibangun suatu jaringan wireless multi hop yang andal, efektif dan berkecepatan tinggi. Kata kunci : multi hop, routing, wireless sensor network, sensor digital, IoT, access point, base statio
ANALISA IMPLEMENTASI VRRP (VIRTUAL ROUTER REDUNDANCY PROTOCOL) BERBASIS MIKROTIK PADA JARINGAN HOMEGRID
Full text linkVirtual Router Redundancy Protocol (VRRP) dikembangkan untuk menghilangkan kegagalan dalam suatu node tunggal sistem gateway, sehingga meyebabkan terputusnya link jaringan. VRRP mampu menyediakan akses link jalur routing secara redundan. Penelitian kali ini menerapkan teknologi VRRP ini pada jaringan rumahan atau gedung yang memanfaatkan jaringan instalasi listrik sebagai LAN (Local Area Network) yang biasa disebut dengan HomeGrid, dan mengujinya dengan melakukan pengukuran metric QoS. Nilai-nilai QoS yang didapat kemudian dibandingkan dengan standar QoS pada TIPHON sebagai pembuktian bahwa kondisi jaringan masih dalam keadaan batas normal. Sistem diuji dengan menggunakan 3 (tiga) skema untuk mendapatkan hasil yang maksimal. Kondisi jaringan dengan menggunakan system VRRP ini hanya membutuhkan waktu downtime sangat singkat, bila dilihat dari monitoring packet capture memakan waktu hanya 3 sampai 4 detik pada semua skema. Dengan demikian kemampuan teknologi system VRRP telah teruji dan mampu menyediakan link yang high availability.

ANALISA IMPLEMENTASI POWER LINE COMMUNICATION SEBAGAI BACKBONE WI-FI EXTENDER
Full text linkPada penelitian ini telah dilakukan analisis tentang implementasi power line communication sebagai backbone Wi-Fi extender, sebagai referensi maupun sebagai acuan dalam memanfaatkan jaringan instalasi listrik yang ada untuk digunakan sebagai jaringan data ataupun sebagai backbone untuk pendistribusian data dalam suatu rumah atau gedung yang disertai dengan analisa QoS nya.Dari langkah-langkah pengujian yang sudah dilakukan, penggunaan teknologi PLC/Homeplug ini sudah cukup mumpuni untuk digunakan sebagai infrastruktur LAN ataupun sebagai backbone jaringan. Pengujian dan pengukuran menggunakan Jperf/Iperf, dengan background bandwidth yang sudah ditentukan untuk ketiga jenis skenario implementasi, membuktikan nilai-nilai QoS yang didapat masih dalam nilai-nilai kualifikasi TIPHON. Pada saat jaringan dibebani dengan traffic data streaming video terjadi kenaikan jitter dan delay, tetapi nilai QoS yang didapat masih dalam area nilai kualifikasi TIPHON. Dari pengujian video streaming ini dapat disimpulkan bahwa tidak ada penurunan kualitas dari hasil video secara kasat mata, walaupun kondisi jaringan listrik dalam kondisi beban penuh (semua peralatan listrik dinyalakan). Kata kunci : power line communication, PLC, homeplug, backbone, QoS, jitter, delay, packet loss, bandwidth, throughput, TIPHO
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
