VIDEO STREAMING DENGAN VIDEOLAN PROJECT
Get PDFStreaming is process of continuing data sending by broadcasting trough internet which showed by streaming application at PC client. The sending data packaging is compressing to make sending process is easy. Streaming can be done by input media variation and client has a change to benefit just after server sending the distreaming data and running in VLC media player. VideoLAN Client (VLC) is a media to streaming which can be applied as transmitter and receiver. VLC can compress and decompress audio and video data from some input media. It shows data result of streaming which have picture and voice quality as well as the source
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Pengenalan Bentuk Benda Berdasarkan Sinyal Suara dengan Transducer Mikrofon dan Teknologi Kinect
Get PDFVoice processing or speech recognition is growing rapidly hence it can be used for various applications such as moving a system or motion control and multimedia-based learning media. Implementation of speech recognition and image detection in this study using microphone transducer and kinect technology. This study aims to produce a system that can identify and recognize an object with word commands, such as circles, triangles, rectangles and many. In sound processing, sound feature extraction is carried out with Mel-Frequency Cepstrum Coeffecient (MFCC). Word modeling was done using statistical modeling, namely the Hidden Markov Model (HMM). HMM is able to provide an efficient mechanism for statistically modeling diversity in words or words. Data were collected with offline and online microphone transducers. This study matches the pattern of words through training and testing process. The output of this system is a recognizable word based on the highest probability and displaying the object shape based on the recognized word, namely circle, triangle and quadrilateral. Test results with mirofon tranducers, for 85% trained sources, 81.5% untrained sources, and 84% untrained Kinect source testing hence that word recognition systems can be implemented with Kinect technology.

Implementasi pengenalan suara dan deteksi citra pada penelitian ini menggunakan transducer mikrofon dan teknologi kinect. Penelitian ini bertujuan untuk menghasilkan sistem yang dapat mengidentifikasi dan mengenali suatu objek dengan perintah kata, seperti lingkaran, segitiga, segiempat dan segibanyak. Dalam pengolahan suara dilakukan ekstraksi ciri suara dengan Mel-Frequency Cepstrum Coeffecient (MFCC). Pemodelan kata dilakukan dengan menggunakan pemodelan statistik yaitu Hidden Markov Model (HMM). HMM mampu memberikan mekanisme yang efisien untuk memodelkan secara statistik keragaman dalam ucapan atau kata. Pengambilan data sampel dengan transducer mikrofon secara offline dan online. Pada penelitian ini pencocokan pola kata melalui proses pelatihan dan pengujian kata. Keluaran sistem ini berupa kata yang dikenali berdasarkan probabilitas tertinggi dan menampilkan bentuk benda berdasarkan kata yang dikenali. Prosesnya setelah kata dikenali, sistem akan mentracking citra benda berdasarkan bentuk benda kemudian menampilkan bentuk benda yaitu lingkaran, segitiga, segiempat dan segibanyak. Hasil pengujian dengan tranducer mirofon, untuk sumber terlatih 85%, sumber tidak terlatih 81,5%, dan pengujian dengan Kinect sumber tidak terlatih 84% sehingga sistem pengenalan kata dapat diimplementasikan dengan teknologi Kinect.

Variations on the Author
Get PDF“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
Get PDFWe 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
Perancangan Dan Realisasi Antena Mikrostrip Monopole Segiempat Pada Frekuensi 546 Mhz Untuk Aplikasi Dvb-T
Get PDFAntena mikrostrip adalah suatu konduktor metal yang menempel diatas groundplane yang diantarannya terdapat bahan dielektrik. Antena mikrostrip terdiri atas 3 bagian utama yaitu patch, substrate dan groundplane. Antena mikrostrip yang dapat digunakan dalam konsep aplikasi DVB-T. Sistem DVB-T (Digital Video Broadcasting Terestrial), merupakan sistem penyiaran langsung dari pemancar bumi (terrestrial). Pada penelitian ini dibuat antena mikrostrip monopole untuk DVB-T dengan menggunakan PCB double layer dan software Zeland. Antena ini dirancang pada frekuensi 546 MHz. Bahan yang digunakan adalah PCB epoxy (FR4) double layer dengan ketebalan bahan 1.6 mm dan konstanta dielektrik sebesar 4.7 mm. Antena mikrostrip tersebut diuji untuk mendapatkan nilai frekuensi resonansi, bandwidth, VSWR, HPBW, Gain dan polaradiasi yang kemudian hasilnya dibandingkan dengan hasil simulasi menggunakan software Zeland Program Manager (IE3D). Pada hasil pengukuran antena diperoleh hasil untuk antena mikrostrip diantaranya nilai return loss = -25 dB pada frekuensi = 545 MHz, bandwidth = 140 MHz, dengan nilai VSWR = 1.48 dB, HPBW = 75o dan polaradiasi berbentuk Bidirectional
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
