Abstract

Industrial automation is largely based on PLC-based control systems. They are used to monitor and control a plant or equipment in industries such as water and waste control, energy, oil and gas refining and transportation. Automation also increases product quality, productivity and decreases breakdown. Conventional equipments or systems are prone to errors due to involvement of humans for data collection and processing using complicated mathematical expressions. Computer integrated manufacturing, computer numerical control; robots, flexible manufacturing system, automated inspection and process control are directing the technology toward one goal, the fully automated factory of the future. Coming to Induction motors, in the conventional case due to long use of a particular induction motor in oil rig related plants more mechanical faults arise due to overheating and may lead to failure which affects production. In case of using two or more induction motors and automating the duty cycle shifting using PLC, the effectiveness of the system increases. Also in case of tripping of a particular motor, other idle motors backs up the operation thereby preventing the plant to go to standstill, hence increasing the overall plant efficiency.

Abstract

Broadband wireless networks are increasing in popularity owing to current advances in technology. For large area network deployment, IEEE 802.16 mesh networks can provide a wide coverage, high speed and high quality multimedia service. IEEE 802.16 mesh configuration eliminates the need to have direct links between subscriber stations (SSs) and the base station (BS); a node can choose the links and path of the highest quality to transmit data and avoid the congested areas. To provide better Quality of Service (QoS) over the 802.16 network, the network layer 3 (L3) and layer 2 (L2) QoS must be integrated. Hence, cross-layer mechanisms were designed and incorporated into our previously proposed IEEE 802.16 QoS frameworks. Taking into consideration resource utilization and QoS requirements, we devised various scheduling schemes to determine their effects on the IEEE 802.16 mesh network. Our performance evaluation demonstrates that the proposed framework with enhancement scheduling has higher throughput, lower delay and signal cost than comparable systems. In this paper, we provide an appraisal of our proposed scheme. DOI: http://dx.doi.org/10.11591/telkomnika.v11i12.3708

Abstract

For the “early convergence” or the “genetic drift” of the genetic algorithm, this paper proposes a new genetic algorithm based on P system. Based on the parallel mechanism of P system in membrane computing, we put forward the new P system based genetic algorithm (PBGA). So that we can improve the performance of GA.

Abstract

Bring Your Own Device (BYOD) is a new approach to optimize the use of Information Technology (IT) devices to carry out their work task. The study of BYOD is focused on work activities that perform by IT worker using IT device in public sector. Work activities can provide important insights into IT device portfolio development, end-user segmentation process and the role of IT workers in public sector. The propose of this study is to explore work process of bringing your own devices to support green computing. A conceptual framework of BYOD work process in public sector through integration of IT devices and end-user segmentation to support green computing was developed based on systematic literature review to highlight the implementation of BYOD. This framework considers that work activities based on IT worker, IT device portfolio and end-user segmentation are the main key for public sector to support green computing. This framework is an initial research for researchers and practitioners to further examine BYOD practices in public sector. In addition, to highlight an important gap, this paper explains how different work activities using different IT device influence the IT worker to select the suitable IT device for BYOD that support green computing.

Abstract

Recent days witnessed considerable developments in the field of wireless sensor networks (WSNs). The applications of these networks can be seen in the simple consumer electronic devices as well as in the advanced space technology. The communication protocols are of prior importance and interest; the low-energy adaptive clustering hierarchy (LEACH) protocol is used to enhance the performance of power consumption for the WSNs nodes. The efficiency of a wireless network can be affected by different factors, such as the size of the WSN and the initial energy of the sensor node. This can inspire the researchers to develop the optimum structure of the WSNs to get its desired functionality. In this paper, the performance of the low-energy adaptive clustering hierarchy (LEACH) protocol is investigated using MATLAB to study the effect of the initial energy of the sensor node and the WSN size on the number of the running nodes. It is found that increasing the initial energy of a sensor node increases the life time of the node and hence the number of the running nodes. It has been also approved that the WSN size has an inverse proportion with the number of running sensor nodes during the use of LEACH protocol.

Abstract

In order to increase the accurate rates of the iris recognition, this paper proposes iris recognition method based on the combination of second generation curvelet transform and the Support Vector Machine Category correction. The images collected from iris image acquisition system are identified. First, rotation correction of iris and spot removal are carried out for collecting iris images. Then, iris images are through rectangular conversion, filter to extract edge point element from which judge the iris image quality. Furthermore, LoG operator is adopted to extract high-frequency energy on both sides of the iris pupil local area, and special judgment is taken out for pupil blocking by eyelids, eyelashes on basis of the energy spectrum. Finally, the cuckoo search algorithm is designed to optimize iris classifier of SVM parameters, and with the second generation curvelet transform algorithm, to complete iris recognition Results show that iris recognition with the CASIA 1.0 database, which contains 756 images of 108 eyes, is an efficient method for iris recognition with high recognition accuracy of iris image. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4289

Abstract

Among the various parameters and constraints considered that are affected by optimal deployments, performance as per the mac layer has attained limited attention. This article is aimed at two things. Firstly, it aims to understand the packet delivery parameters for convergecast communication pattern ideal for Zigbee based wireless sensor networks. Secondly, it aims to suggest enhancements through proposing a quasi based deployment pattern, that may help boost the performance to acceptable levels. We simulate and observe the packet based statistics at the mac layers employing different protocols like AODV, DSR. This paper is also an effort to suggest the use of Quasi based deployment strategy comparable to the existing random and deterministic methods. The inferences obtained are for zigbee networks encorporating both peer to peer (using a tree based topology) and star (using a graph based topology) WSN architectures. A quasi based deployment pattern offers scope for improvement of the reliability metrics which is the sole accountability of the mac layer, irrespective to the protocol employed at the higher levels or the backbone structure for communication. DOI: http://dx.doi.org/10.11591/telkomnika.v15i1.8074

Abstract

  To analyze the influence of the equipment and support structure on the system seismic response, two-particle model for UHV electric equipment-support structure system was established. The seismic response of the system was calculated by mode-superposition response spectrum method. The case study on the typical 1000kV electric equipment-support structure system verified the availability of the two-particle model. Based on the structure characteristics of UHV equipment and support structure, the effect of support structure on the system seismic response was obtained by parametric analysis about stiffness and mass of support structure. It was showed that suitable support structure could reduce earthquake load of equipment and improve seismic resistance of system. Conclusions provide reference for the design of support structure. DOI: http://dx.doi.org/10.11591/telkomnika.v10i8.1648
