Abstract

In the premise of meeting the quality of network service, how to effectively cover the monitoring area and how to prolong the network lifetime has become one of the wireless sensor network researches. Therefore, this paper proposes heterogeneous nodes based on association covering algorithm. On one hand, this algorithm is handled through the Poisson model of structure joint probability density formula and it is also based on the node density formula to establish sensor node in the monitoring area in order to efficiently cover the focused target. On the other hand, it updates through the node's own state scheduling mechanism and converts neighbor nodes dynamically about matching scheduling, which can balance the monitoring area sensor node residual energy and node energy consumption. Therefore it can achieve the purpose of prolonging network lifetime .Finally, the simulation results show that the algorithm not only can use fewer nodes to effectively cover the monitoring area completely and improve the coverage of the network but also can optimize resource allocation and prolong the network lifetime. DOI: http://dx.doi.org/10.11591/telkomnika.v11i11.3492

Abstract

Efficient and safe traffic control strategy for emergency vehicle can reduce its travel time and avoid secondary accident. Based on the analysis of its requirement and object, we proposed a novel control strategy at intersection according to the status of emergency vehicle, which can be divided into three parts: “approaching”, “passing “and “recovering”, Furthermore potential safety risk caused by emergency vehicle was also taken into account when making control strategy.From the case study we conclude that with control strategy in this paper delay of emergency vehicle can be sharply decreased by 68.63% with only 19.86% loss of average delay of background traffic.  DOI : http://dx.doi.org/10.11591/telkomnika.v12i5.4928

Abstract

This paper presents an analysis of reflection phase of reflectarray antenna based on high loss organic substrate material. Paper substrate material derived from recycled materials was characterized for dielectric material properties. The material shows excellent dielectric material properties with permittivity of 1.63 and loss tangent of 0.048. Effect of substrate height variation over the reflection phase has been discussed. Full wave analysis of the simulated model depicts that the reduction in substrate height after a certain point results in reflection phase distortion of reflectarray element. Validation of the results has been done by simulation, fabrication and scattering parameters measurements of a rectangular patch element on proposed substrate material. The results show a broadband frequency response of 355 MHz and a phase range of 301º at a phase gradient of 0.14 º/MHz.

Abstract

Internet of Things (IoT) - empowered data framework arrangements are developing in different spaces, for example, remote social insurance, keen coordination’s, farming et cetera. In the mean time, Business Development Management Frameworks (BDMF) has turned out to be promising instruments for driving and overseeing gadgets inside IoT frameworks. Be that as it may, past works have not completely tended to how the IoT-based BDMF can proceed with their execution when the included IoT gadgets don't have a dependable Internet association. In this paper, we propose a framework outline for decentralized device to device (D2D) - based BD execution, where versatile hubs have the ability of both executing BDs additionally moving BD execution to different hubs amid runtime. We apply this plan to the field of shrewd coordination’s, keeping in mind the end goal to empower savvy products checking. The exhibited merchandise observing arrangement empowers responding to occasions when they happen, while likewise producing a hint of the checking execution history. A model concentrating on the movement usefulness of the stage has been actualized and tried to assess its execution with regards to the specified savvy coordination’s situation.

Abstract

Attending activities organized by the university or institution is one of the important criteria that must be fulfilled by students for multiple purposes. Whether it is by attending classes, or any other activities, the main concern is focused on the process of recording students’ attendance. The use of a paper-based manual system to record students’ attendance is still being widely used due to the lack of an e-management system. These approaches have a lot of disadvantages due to the nature of the paper which is a fragile material - also an expensive cost to procure and produce. This paper, relying on Radio Frequency Identification (RFID), designed and developed an electronic system known as Activity Attendance Monitoring System (AAMS) that utilizes readily available resource – student card, as the student identification when attending an activity. Results from the validation, execution and continuous test suggest that AAMS can be effectively implemented to monitor and record student’s attendance. The main contribution of the study is the design and development model that capable of monitoring students’ activity attendance in university activities context. Developers and researcher in the area can adopt the proposed design and development model in formulating a similar system in managing activity attendance.

Abstract

To choose best representation for image cluster, we analyzed the distinguish ability of three typical image representations, color histogram, Gabor texture and geometric moment by fitting image distance curve, and show different retrieval results of image retrieval for different image representations. To depict the distinguish ability of different image representations, we present a cluster discriminant index called Simplified Overall Cluster Quality, which constitutes cluster compaction and cluster separation, and the experiment results show that the image representation with best distinguish ability also possesses maximum discriminant index value. This index can be used to determine optimal representation for clustering or the order of feature used to cluster.DOI: http://dx.doi.org/10.11591/telkomnika.v12i8.5458

Abstract

Since the maintenance of HSR depends both on inner geometries and outer geometries information of track, it’s necessary that the survey technologies could measure the smoothness and coordinates of track in a high-density manner. But the existing technologies for track survey are either inaccurate or inefficient for HSR maintenance, the problem about track survey arises with the rapid development of high-speed rail (HSR) in China. To meet the demands on track smoothness survey of existing line, a method denoted as 3-D Constraints Method is introduced in this paper. The general principle of the method is obtaining center line locus with location information by means of survey trolley and CP-Ⅲ stakes. By measuring the distances between trolley and CP-Ⅲ stakes, the boundary condition could be determined. So, the problem of center line calculation is transformed into the problem of definite integral for FOG signals. Accordingly, an algorithm of coordinate calculation is given. With the constraints form CP-Ⅲ stakes, the coordinates of center line could be obtained in a defined accuracy. Finally, the simulation result shows that the method is effective. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2556

Abstract

The articulation of Arabic phonemes is essential for the Malay community since Arabic language is mandatory to perform worship. Hence, in this paper, an acoustical analysis of Arabic phonemes for vowels /u/ and /u:/ is discussed based on tokens pronounced by Malay speakers. The experimental results showed that the Malay speakers are inclined to utter these Arabic phonemes similar to the native speakers and it was also found from the analysis that the vowel /u/ and /u: was articulated as high-back vowels. Conversely, the vowel /u/ was located lower than /u:/ as in the vowel-space. Alternatively results also showed that /u/ and /u:/  is higher than the other vowels specifically /a/ and /a:/. In addition, the statistical analysis showed that the formant frequencies of both short and long dummah for formant frequency F1, F2 and F3 have more variation in terms of /u/ as compare to /u:/. In contrast formant frequency F4 and F5 are more diversity in terms of /u:/.

Abstract

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
