Pengenalan Ucapan Kata Berkorelasi Tinggi
Full text linkPenelitian pengenalan ucapan oleh komputer dengan metode stokastik sudah mulai dipopulerkan sejak tahun 1970-an. Salah satu bentuk metode pendekatan stokastik adalah Hidden Markov Model. Penelitian ini menggunakan model tersebut untuk menganalisis dan mengenali delapan ucapan kata bahasa Indonesia yang memiliki korelasi tinggi antara kata yang satu dengan kata yang lainnya, yaitu: muka, muak, kamu, kaum, masuk, kamus, kusam dan sukma. Analisis LPC (Linear Predictive Coding) digunakan untuk mencari ciri-ciri penting setiap sinyal suara i kata-kata terucap. Selanjutnya HMM (Hidden Markov Model) digunakan untuk pelatihan dan pengenalan. Hasil penelitian menunjukkan bahwa rata-rata pengenalan seluruh kata cukup signifikan yaitu di atas 97%
ALAT PENGUKUR PEMAKAIAN ENERGI LISTRIK MENGGUNAKAN SENSOR OPTOCOUPLER DAN MIKROKONTROLER AT89S52
Full text linkkWh-meter as an each hour electrical energy consumption measurer is still using conventional tools which only recordsthe amount of electrical energy used in each hour. By using AT89S52 microcontroller and optocoupler sensor, the conventional kWhmeter was modified to be a measurer which is not only display s the amount of the used electrical energy but also shows the value of money in rupiahs that should be paid by the customer. The principle of how this system works is PLN as a power source of kWh-meter moves the disc of kWh-meter when it is in the underload condition. When the disc spin and pass the optocoupler sensor, the sensor will turn on. Each time the disc cuts the beam of light, the sensor will instruct the microcontroller, the main controller, to process the execution instruction. This execution instruction results in the reading ofboth a number of rounds per kWh and an amount of rupiahs display ed in LCD
RANCANG BANGUN SISTEM KEAMANAN KENDARAAN DILENGKAPI DENGAN TEKNOLOGI GPS DAN SMS GATEWAY
Full text linkVehicle theft is one of the most common cases in big cities. The absence of a security system on a vehicle is one of the causes of the case. Therefore, we need a security system on the vehicle in the form of an alarm and can also perform the tracking function.
This study aims to design a vehicle security system using GPS and SMS Gateway technology. This system uses the u-blox Neo6m GPS module, GSM SIM 800L v2 module and Arduino Uno microcontroller. The tracking system uses data from GPS coordinates sent to the user's smartphone number and displayed on the Google Maps application.
The accuracy of GPS coordinates in this system when compared to GPS on smartphones has a gap of between 1 - 26 meters. The response time when the user sends a command to track the vehicle to get a reply sms that is ± 37.6 seconds
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
