The results of the finite element analysis indicated that the expansion ratio of the tube was mainly affected by the radius of the punch. However, the rupture was more affected by the punch angle than the radius of the punch. The existence of a specific punch angle, at which rupture did not occur, even if the radius of the punch was increased, was found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Expansion%20tube" title="Expansion tube">Expansion tube</a>, <a href="https://publications.waset.org/search?q=Ductile%20damage" title=" Ductile damage"> Ductile damage</a>, <a href="https://publications.waset.org/search?q=Shear%20failure" title=" Shear failure"> Shear failure</a>, <a href="https://publications.waset.org/search?q=Stress%20triaxiality." title="Stress triaxiality.">Stress triaxiality.</a> </p> <a href="https://publications.waset.org/14635/study-on-rupture-of-tube-type-crash-energy-absorber-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14635/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14635/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14635/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14635/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14635/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14635/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14635/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14635/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14635/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14635/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14635.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1725</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">146</span> Online Measurement of Fuel Stack Elongation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sung%20Ho%20Ahn">Sung Ho Ahn</a>, <a href="https://publications.waset.org/search?q=Jintae%20Hong"> Jintae Hong</a>, <a href="https://publications.waset.org/search?q=Chang%20Young%20Joung"> Chang Young Joung</a>, <a href="https://publications.waset.org/search?q=Tae%20Ho%20Yang"> Tae Ho Yang</a>, <a href="https://publications.waset.org/search?q=Sung%20Ho%20Heo"> Sung Ho Heo</a>, <a href="https://publications.waset.org/search?q=Seo%20Yun%20Jang"> Seo Yun Jang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The performances of nuclear fuels and materials are qualified at an irradiation system in research reactors operating under the commercial nuclear power plant conditions.

In results, the average time (and their standard deviations) of muscular strength reaction EMG signal and hand grip strength was found to be 209.6 ± 56.2 ms and 354.3 ± 54.6 ms, respectively.

In case of washing machine, the life cycle test method of motor is advanced for 3000 cycle test (1cycle = 2hours). However, 3000 cycle test incurs loss for the time and cost. Objectives of this study are to reduce the life cycle test time and the number of test samples, which could be realized by using acceleration factor for the test time and reduction factor for the number of sample.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Accelerated%20life%20cycle%20test" title="Accelerated life cycle test">Accelerated life cycle test</a>, <a href="https://publications.waset.org/search?q=motor%20reliability%20test" title=" motor reliability test"> motor reliability test</a>, <a href="https://publications.waset.org/search?q=motor%20for%20washing%20machine" title=" motor for washing machine"> motor for washing machine</a>, <a href="https://publications.waset.org/search?q=BLDC%20motor." title=" BLDC motor."> BLDC motor.</a> </p> <a href="https://publications.waset.org/10004505/a-study-on-the-accelerated-life-cycle-test-method-of-the-motor-for-home-appliances-by-using-acceleration-factor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10004505/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10004505/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10004505/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10004505/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10004505/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10004505/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10004505/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10004505/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10004505/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10004505/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10004505.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3593</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">141</span> Experimental Technique for Vibration Reduction of a Motor Pumpin Medical Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Young%20Kuen%20Cho">Young Kuen Cho</a>, <a href="https://publications.waset.org/search?q=Dae%20Won%20Lee"> Dae Won Lee</a>, <a href="https://publications.waset.org/search?q=Young-Jin%20Jung"> Young-Jin Jung</a>, <a href="https://publications.waset.org/search?q=Sung%20Kuk%20Kim"> Sung Kuk Kim</a>, <a href="https://publications.waset.org/search?q=Dong-Hyun%20Seo"> Dong-Hyun Seo</a>, <a href="https://publications.waset.org/search?q=Chang-Yong%20Ko">Chang-Yong Ko</a>, <a href="https://publications.waset.org/search?q=Han%20Sung%20Kim"> Han Sung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Many medical devices are driven by motor pumps. Some researchers reported that the vibration mainly affected medical devices using a motor pump. The purpose of this study was to examine the effect of stiffness and damping coefficient in a 3-dimensional (3D) model of a motor pump and spring. In the present paper, experimental and mathematical tests for the moments of inertia of the 3D model and the material properties were investigated by an INSTRON machine. The response surfaces could be generated by using 3D multi-body analysis and the design of experiment method. It showed that differences in contours of the response surface were clearly found for the particular area. Displacement of the center of the motor pump was decreased at K≈2000 N/M, C≈12.5 N-sec/M. However, the frequency was increased at K≈2000 N/M, C≈15 N-sec/M. In this study, this study suggested experimental technique for vibration reduction for a motor pump in medical device. The combined method suggested in this study will greatly contribute to design of medical devices concerning vibration and noise intervention.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Motor%20pump" title="Motor pump">Motor pump</a>, <a href="https://publications.waset.org/search?q=Spring" title=" Spring"> Spring</a>, <a href="https://publications.waset.org/search?q=Vibration%20reduction" title=" Vibration reduction"> Vibration reduction</a>, <a href="https://publications.waset.org/search?q=Medicaldevices" title=" Medicaldevices"> Medicaldevices</a>, <a href="https://publications.waset.org/search?q=Moment%20of%20Inertia" title=" Moment of Inertia"> Moment of Inertia</a> </p> <a href="https://publications.waset.org/4545/experimental-technique-for-vibration-reduction-of-a-motor-pumpin-medical-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/4545/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/4545/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/4545/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/4545/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/4545/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/4545/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/4545/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/4545/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/4545/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/4545/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/4545.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1901</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">140</span> Auto Tuning PID Controller based on Improved Genetic Algorithm for Reverse Osmosis Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jin-Sung%20Kim">Jin-Sung Kim</a>, <a href="https://publications.waset.org/search?q=Jin-Hwan%20Kim"> Jin-Hwan Kim</a>, <a href="https://publications.waset.org/search?q=Ji-Mo%20Park"> Ji-Mo Park</a>, <a href="https://publications.waset.org/search?q=Sung-Man%20Park"> Sung-Man Park</a>, <a href="https://publications.waset.org/search?q=Won-Yong%20Choe"> Won-Yong Choe</a>, <a href="https://publications.waset.org/search?q=Hoon%20Heo"> Hoon Heo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An optimal control of Reverse Osmosis (RO) plant is studied in this paper utilizing the auto tuning concept in conjunction with PID controller. A control scheme composing an auto tuning stochastic technique based on an improved Genetic Algorithm (GA) is proposed. For better evaluation of the process in GA, objective function defined newly in sense of root mean square error has been used. Also in order to achieve better performance of GA, more pureness and longer period of random number generation in operation are sought. The main improvement is made by replacing the uniform distribution random number generator in conventional GA technique to newly designed hybrid random generator composed of Cauchy distribution and linear congruential generator, which provides independent and different random numbers at each individual steps in Genetic operation. The performance of newly proposed GA tuned controller is compared with those of conventional ones via simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Genetic%20Algorithm" title="Genetic Algorithm">Genetic Algorithm</a>, <a href="https://publications.waset.org/search?q=Auto%20tuning" title=" Auto tuning"> Auto tuning</a>, <a href="https://publications.waset.org/search?q=Hybrid%20random%0Anumber%20generator" title=" Hybrid random number generator"> Hybrid random number generator</a>, <a href="https://publications.waset.org/search?q=Reverse%20Osmosis" title=" Reverse Osmosis"> Reverse Osmosis</a>, <a href="https://publications.waset.org/search?q=PID%20controller" title=" PID controller"> PID controller</a> </p> <a href="https://publications.waset.org/11010/auto-tuning-pid-controller-based-on-improved-genetic-algorithm-for-reverse-osmosis-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11010/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11010/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11010/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11010/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11010/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11010/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11010/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11010/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11010/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11010/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11010.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3127</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Integrated Simulation and Optimization for Carbon Capture and Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Taekyoon%20Park">Taekyoon Park</a>, <a href="https://publications.waset.org/search?q=Seok%20Goo%20Lee"> Seok Goo Lee</a>, <a href="https://publications.waset.org/search?q=Sung%20Ho%20Kim"> Sung Ho Kim</a>, <a href="https://publications.waset.org/search?q=Ung%20Lee"> Ung Lee</a>, <a href="https://publications.waset.org/search?q=Jong%20Min%20Lee"> Jong Min Lee</a>, <a href="https://publications.waset.org/search?q=Chonghun%20Han"> Chonghun Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>CO<sub>2 </sub>capture and storage/sequestration (CCS) is a key technology for addressing the global warming issue.

In selective mutation, individuals are first ranked and then additionally mutated one bit in a part of their strings which is selected corresponding to their ranks. This selective mutation helps genetic algorithms to fast approach the global optimum and to quickly escape local optima. This results in increasing the performances of genetic algorithms. We measured the effects of selective mutation with four function optimization problems.

Wi-Fi communication range is limited in collaborative control of UAV and UGV. Thus, to secure a stable communications, UAV and UGV have to be kept within a certain distance from each other. But existing method which uses UAV Vertical Camera to follow the motion of UGV is likely to lose a target with a sudden movement change. Eventually, UGV has disadvantages that it could only move at a low speed and not make any sudden change of direction in order to keep track of the target. Therefore, we suggest utilizing AR Drone UAV front camera to track fast-moving and Omnidirectional Mecanum Wheel UGV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Collaborative%20control" title="Collaborative control">Collaborative control</a>, <a href="https://publications.waset.org/search?q=UAV" title=" UAV"> UAV</a>, <a href="https://publications.waset.org/search?q=UGV" title=" UGV"> UGV</a>, <a href="https://publications.waset.org/search?q=Target%20Tracking." title=" Target Tracking."> Target Tracking.</a> </p> <a href="https://publications.waset.org/5871/collaborative-tracking-control-of-uav-ugv" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5871/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5871/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5871/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5871/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5871/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5871/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5871/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5871/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5871/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5871/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5871.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2944</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">131</span> Structure-vibration Analysis of a Power Transformer(154kV/60MVA/Single Phase)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Young-Dal%20Kim">Young-Dal Kim</a>, <a href="https://publications.waset.org/search?q=Jae-Myung%20Shim"> Jae-Myung Shim</a>, <a href="https://publications.waset.org/search?q=Woo-Yong%20Park"> Woo-Yong Park</a>, <a href="https://publications.waset.org/search?q=Sung-joong%20Kim"> Sung-joong Kim</a>, <a href="https://publications.waset.org/search?q=Dong%20Seok%20Hyun"> Dong Seok Hyun</a>, <a href="https://publications.waset.org/search?q=Dae-Dong%20Lee"> Dae-Dong Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most common cause of power transformer failures is mechanical defect brought about by excessive vibration, which is formed by the combination of multiples of a frequency of 120 Hz.

Genetic algorithms are one of the evolutionary algorithms inspired from nature and utilized in the field of clustering. In this paper, we propose two algorithms to solve the initialization problem, Genetic Algorithm Initializes KM (GAIK) and KM Initializes Genetic Algorithm (KIGA).

FMO can not only support error-resilience, but also control the size of video packets for different network types. However, it is well-known that the number of bits required for encoding the frame is increased by adopting FMO. In this paper, we propose a novel algorithm that can reduce the bitrate overhead caused by utilizing FMO. In the proposed algorithm, all MBs are grouped in SGs based on the similarity of the transform coefficients. Experimental results show that our algorithm can reduce the bitrate as compared with conventional FMO. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Data%20Partition" title="Data Partition">Data Partition</a>, <a href="https://publications.waset.org/search?q=Entropy%20Coding" title=" Entropy Coding"> Entropy Coding</a>, <a href="https://publications.waset.org/search?q=Greedy%20Algorithm" title=" Greedy Algorithm"> Greedy Algorithm</a>, <a href="https://publications.waset.org/search?q=H.264%2FAVC" title=" H.264/AVC"> H.264/AVC</a>, <a href="https://publications.waset.org/search?q=Slice%20Group." title=" Slice Group."> Slice Group.</a> </p> <a href="https://publications.waset.org/10193/bitrate-reduction-using-fmo-for-video-streaming-over-packet-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10193/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10193/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10193/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10193/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10193/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10193/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10193/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10193/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10193/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10193/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10193.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1306</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">120</span> Implementation of IEEE 802.15.4 Packet Analyzer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sung%20Jun%20Ban">Sung Jun Ban</a>, <a href="https://publications.waset.org/search?q=Hyeonwoo%20Cho"> Hyeonwoo Cho</a>, <a href="https://publications.waset.org/search?q=ChangWoo%20Lee"> ChangWoo Lee</a>, <a href="https://publications.waset.org/search?q=Sang%20Woo%20Kim"> Sang Woo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A packet analyzer is a tool for debugging sensor network systems and is convenient for developers. In this paper, we introduce a new packet analyzer based on an embedded system. The proposed packet analyzer is compatible with IEEE 802.15.4, which is suitable for the wireless communication standard for sensor networks, and is available for remote control by adopting a server-client scheme based on the Ethernet interface. To confirm the operations of the packet analyzer, we have developed two types of sensor nodes based on PIC4620 and ATmega128L microprocessors and tested the functions of the proposed packet analyzer by obtaining the packets from the sensor nodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Sensor%20network" title="Sensor network">Sensor network</a>, <a href="https://publications.waset.org/search?q=embedded%20system" title=" embedded system"> embedded system</a>, <a href="https://publications.waset.org/search?q=packet%20analyzer." title=" packet analyzer."> packet analyzer.</a> </p> <a href="https://publications.waset.org/15786/implementation-of-ieee-802154-packet-analyzer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/15786/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/15786/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/15786/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/15786/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/15786/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/15786/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/15786/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/15786/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/15786/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/15786/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/15786.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2204</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">119</span> Observer Design for Chaos Synchronization of Time-delayed Power Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jui-Sheng%20Lin">Jui-Sheng Lin</a>, <a href="https://publications.waset.org/search?q=Yi-Sung%20Yang"> Yi-Sung Yang</a>, <a href="https://publications.waset.org/search?q=Meei-Ling%20Hung"> Meei-Ling Hung</a>, <a href="https://publications.waset.org/search?q=Teh-Lu%20Liao"> Teh-Lu Liao</a>, <a href="https://publications.waset.org/search?q=Jun-Juh%20Yan"> Jun-Juh Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The global chaos synchronization for a class of time-delayed power systems is investigated via observer-based approach.
