ARM 9 Based Intelligent System for Biometric Figure Authentication

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/4195
V. Krishna Chaitanya Reddy , B. Sukumar , S. Javeed Hussain
Now a day’s some universities in India are enforcing afiliated colleges to implement biometric fingerprint attendance system to monitor student attendance. This sytem requiresbiometric fingerprint scanner need to be installed in affiliated   college where student studying and it is monitored by the university online. As finger print scanner is placed at affiliated college which is far away from the university, there is possibility of adding fake finger print into the scanner which can be used for proxy attendance of student who is not attending the college. In this paper, the proposed system is designed in such a way that, the acquired fingerprint of the student is initially stored in the database with complete student profile and photograph. And, when the student places his fingerprint it compares with stored database. If fingerprint matches it displays the student photo. The proposed intelligent system includes R305 fingerprint sensor and ARM 9 processor. We used RS232 for interfacing with system and visual studio 2008 software for designing the interface. This attendance system is verified practically with students and we obtained the desired results accurately. DOI: http://dx.doi.org/10.11591/telkomnika.v13i2.7042

Optimal Warranty Policy Considering Two-dimensional Imperfect Preventive Maintenance for Repairable Product

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/4196
Xin Yue Li , Yun Xian Jia
For some kinds of products, such as car, aircraft, government acquisition, the consumers have strict requirements to the reliability of these products. Then the manufacturer is inclined to provide the two-dimensional preventive maintenance policy to take the usage degree of the product into account. As a result, two-dimensional preventive maintenance policy in the warranty period has recently obtained increasing attention from manufacturers and consumers. In this paper, we focused on the optimization of based warranty cost and proposed a new expected cost model of the two-dimensional imperfect preventive maintenance policy from the perspective of the manufacture. The optimal two-dimensional preventive maintenance was obtained by minimizing based warranty cost. And asymmetric copula function was applied to modeling the failure function of the product. At last, numerical examples are given to illustrate the proposed models, of which the results prove the model effective and validate. DOI: http://dx.doi.org/10.11591/telkomnika.v13i2.7043

PK Patra , Padma Lochan Pradhan
The preventive control is one of the well advance controls for recent security for protection of data and services from the uncertainty. Because, increasing the importance of business, communication technologies and growing the external risk is a very common phenomenon now-a-days. The system security risks put forward to the management focus on IT infrastructure (OS). The top management has to decide whether to accept expected losses or to invest into technical security mechanisms in order to minimize the frequency of attacks, thefts as well as uncertainty. This work contributes to the development of an optimization model that aims to determine the optimal cost to be invested into security mechanisms deciding on the measure component of UFS attribute. Our model should be design in such way, the Read, Write & Execute automatically Protected, Detected and Corrected on RTOS. We have to optimize the system attacks and down time by implementing RWX ACM mechanism based on semi-group structure, mean while improving the throughput of the Business, Resources & Technology. DOI: http://dx.doi.org/10.11591/telkomnika.v13i2.7059

A Novel Method for Sensing Obscene Videos using Scene Change Detection

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/4207
Rashed Mustafa , Dingju Zhu
Video scene change detection has great importance of managing and analyzing large amount ofvideos. Traditionally this technique used for indexing, segmenting and categorizing different typesof videos. Very few works addressed to classify obscene using scene change detection method. Inthis research we proposed a simple approach for sensing objectionable videos by observing scenechanges into different video genres. Video scenes are grouped into set of key frames. Afteranalyzing duration of each scene and counting the number of key frames of designated scene, ithas been shown that obscene videos have infrequent scene changing nature. While in sports,dramas, music and action films have large number of scene changes. We used six types of videogenres and the decision has been made by setting a threshold based on extracted key. DOI:  http://dx.doi.org/10.11591/telkomnika.v13i2.6873

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/4208
V Thiyagarajan , N.P. Subramanium
The paper develops an approach based on wavelet technique for the evaluation and estimation of harmonic contents of power system waveform. The proposed algorithm decomposes the signal waveforms into the uniform frequency sub-bands corresponding to the odd harmonic components of the signal. The proposed implementation of algorithm determines the frequency bands of harmonics which retain both the time and frequency relationship of the original waveforms and uses a method to suppress those harmonics. The wavelet algorithm is selected to obtain compatible output bands with the harmonic groups defined in the standards for power-supply systems. A comparative analysis will be done with the input and the results obtained from the wavelet transform (WT) for different measuring conditions and Simulation results are given. DOI:  http://dx.doi.org/10.11591/telkomnika.v13i2.6983

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/4210
Made Sudarma
Balinese papyrus is one of the media to write the ideas from minstrels in ancient times. Currently, many ancient literatures which are written in the papyrus, that also very difficult to identify because the writings were beginning to rot or fade influenced by age. In this study takes the Balinese papyrus characters as its object. The improvement of the image quality in image processing of the characters here refers to the change for the quality of the image before its next development. There is the process of identifying the color space to spot the shape of the papyrus characters. The difference of the colors is so small so that it needs CIELab to process the identification out of its background and noise. DOI:  http://dx.doi.org/10.11591/telkomnika.v13i2.7086

Wenlian Zhan , Zhulin Shen
Reading is a complex cognitive process. Through eye tracking techniques the cognitive features can be observed in depth, and therefore a better grasp of the instant cognitive processing of language can be achieved. Compared to traditional methods, the greatest advantage of eye tracking is that is that the reader proceeds with reading coherently and fluently without interrupt and interference, which secures the results in higher ecological validity.  This paper is mainly about studies on eye movement features in ESL reading, and particularly illustrates eye movement patterns, the relationship between eye movement and perceptual processing, and eye movement control, aiming at providing some basic evidences for explaining the relationship between eye movement behavior and cognitive processing thus helping to solve some theoretical problems in reading. DOI:  http://dx.doi.org/10.11591/telkomnika.v13i2.6936
