Design of Prototype Payment Application System With Near Field Communication (NFC) Technology based on Android
Full text linkoai:ojs2.comengapp.unsri.ac.id:article/1Since the late 1990s, people have enjoyed a comfortable lifestyle. Mobile devices supported by the development of wireless networks have spread throughout the world. People can get information, order tickets, download songs and perform commercial transactions, called mobile commerce. Mobile commerce applications become the most popular application for mobile device users who want to do business and financial transactions easily and securely, anytime and anywhere they are. Today the use of physical cash is experiencing a decline in popularity in the business world, because it is being replaced by non-physical payments are often called electronic money (e-money). An important technology behind mobile payments is called Near Field Communication (NFC). As an indication that the NFC has tremendous business potential, leading companies like Nokia, Microsoft, Visa Inc., and MasterCard Worldwide and NXP Semiconductors, is actively engaged on them. Payment processing integrated with NFC technology based mobile operating system that is a trend today is Android that support NFC technology is version 2.3.3 Gingerbread. The prototype application is designed to pay for 2 on the user side of the user as consumer and the merchant side as a trader or seller by using the handset that already have NFC technology is Google Samsung Nexus S. Pay an application prototype also implements the concept of security in e-commerce transactions by using the protocol-to-Tag Tag so that the user needs for security and comfort during the financial transaction are met.

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
Sensor Fusion and Fuzzy Logic for Stabilization System of Gimbal Camera on Hexacopter
Full text linkHexacopter has the ability to fly in the air can be used as an air monitoring system. To get the video or images that have good quality then it is used gimbal camera as a movement stabilizer and vibration damping. Stabilization System consists of two axes, x axis (roll) and y axis (pitch) and has a 2-axis camera gimbal controller which is have microcontroller ATMEGA 328 that serves to regulate the stability of the gimbal camera. The Input of this system is derived from accelerometer and gyroscope sensors that are within the sensor module MPU 6050, to determine the tilt position of hexacopter. The output of this sensor will be filtered first using complementary filters that serve to reduce noise of both sensors and complement advantages and disadvantages of each sensor. The output of this system is the movement of two brushless motors, brushless roll and pitch, that are controlled with Sugeno fuzzy logic method because it has a simple calculation so the response is faster and more suitable for real-time applications. From the case study with the data of the roll at by 35 º and pitch at by 17 º resulting PWM duty cycle value by -69.47% roll and pitch resulting PWM duty cycle value by -25.5 %, where (-) represents the direction of movement.
IMPLEMENTASI METODE KOMPUTER VISISON SEBAGAI PENGOLAHAN CITRA API PADA KEBAKARAN LAHAN
No full textAbstrak— Pemantauan kebakaran hutan dan semak dapat dilakukan menggunakan citra satelit ataupun kamera dengan metode pengolahan citra menggunakan pesawat tanpa awak (UAV).Pengolahan citra adalah kegiatan memperbaiki kualitas citra agar mudah diinterpretasi oleh manusia komputer. Pada penelitian ini akan menitik beratkan pada merancang dan mengimplementasikan metode komputer vision metrode thresholding, yang digunakan untuk pengolahan data citra kamera yang akan mendeteksi api pada kebakaran lahan. Hasil yang diperoleh adalah nilai HSV dari objek api masuk dalam range rata rata hue : 0 – 65, saturation : 14.5 – 51.4 dan value : 82.4 – 159. Nilai inilah yang akan digunakan sebagai color filtering untuk parameter mendeteksi objek api dan juga sebagai batasan nilai thersholding untuk segmentasi citra. Kata Kunci— Kebakaran lahan, komputer vision, thresholding, pesawat tampan awak
First Person View on Flying Robot For Real Time Monitoring
Full text linkRadio control nowadays not only control the car but can control the copter. First Person View is a way to change the viewpoint of the controller looks like in the copter. By using radio telemetry communication that sends video data from the camera on the copter and will be shown on a display on ground station. Radio telemetry communication will use wideband modulation techniques to transmit video at high speed until the video is shown to be a real time video. The transmitter has been designed which is able to transmit video data up to 1 kilometers. Good quality video data can be sent about 500 meters below. measurement of Peak Signal to Noise Ratio (PSNR) that distance and wall are greatly affect the quality of the video. Deficiencies in the delivery of video communication can be minimized by increasing the gain and transmission power of the radio frequency telemetry and matching between the video telemetry radio and radio control copter
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
