In this paper, amorphous alloy is used as magnetic shielding material of a 10.5 kV 5 kA hydropower generator bus. By comparison with magnetic field analysis of copper, the effect and advantages of amorphous alloy shielding material is discussed. The finite element analysis shows, as to lower frequency magnetic shielding, amorphous alloy can brings less residual magnetic field in outside air of conductors and bus coat. Furthermore, the relationship between thickness of shielding layer and shielding effect is researched, and the results suggest 5 mm should be optimal thickness of this hydroelectric enclosed tube bus.","PeriodicalId":425023,"journal":{"name":"2013 IEEE International Conference of IEEE Region 10 (TENCON 2013)","volume":"451 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122485999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Qiu, Yuanqing Zhao","doi":"10.1109/TENCON.2013.6718964","DOIUrl":"https://doi.org/10.1109/TENCON.2013.6718964","url":null,"abstract":"In this paper, a novel monopole antenna with a compact configuration is proposed, which can operate in the frequency range from 6.8GHz to 37.8GHz. The antenna consists of two main components. One is the two orthogonal half discs with a cavity inside each of them. The other is the circular metallic ground. Firstly, according to the traditonal theory [1], the dimension of each half disc can be determined preliminarily. Then, a cavity is set inside each disc. By using CST simulation software, the opitmal scales of the antenna, at last, can be obtained. From the simulated results, it can be seen that the bandwidth of the antenna is from 6.8GHz to 37.8GHz, meanwhile, the radiation patterns of the antenna stay almost contant over the entire bandwidth. More importantly, there is a dramatic decrease in the dimension of the proposed antenna, compared to the antennas reported in [2]. Hence, the strengths mentioned above contribute to a much wider range of potential application, especially the application in the radio spectrum detection, which demands the bandwidth of antennas to be as wide as possible.","PeriodicalId":425023,"journal":{"name":"2013 IEEE International Conference of IEEE Region 10 (TENCON 2013)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122610266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electron mobility in the VESIMOS-DP (~1440m2/V-s), was found to be increased by 4% in comparison to VESIMOS (~1386 m2/V-s) device. The mobilities in strained layer is depends on the transport direction, either parallel to the original SiGe growth interface or in the perpendicular direction. Carrier mobilities in strained SiGe layer is also based on the local distortion due to the strain effects which contribute to the alloy scattering on the carriers. With the vicinity of DP, the carrier scattering effect has reduced which merits the introduction of DP on the device. Due to the DP layer, improve stability of threshold voltage, VTH and subthreshold slope, S was found for VESIMOS-DP device of various size ranging from 20nm to 80nm justified the vicinity of the DP on improving the performance of the device.","PeriodicalId":425023,"journal":{"name":"2013 IEEE International Conference of IEEE Region 10 (TENCON 2013)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122691183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Internet is public as it were, if we do not control its limit of authority to assure security, it's possible that those attackers do illegal access of important information and destroy them. Not only personal privacy is invaded, but the mass property damage. Therefore, effective access control system has been more and more emphasized these days. To fight against these network attacks, it is necessary to establish an effective and safe access control system; here we proposed a scheme, a key management which called Lagrange interpolation mainly takes access control model as framework, and use Elliptic Curve Cryptography system to enhance security. The fact we choose Lagrange interpolation is the key we use is randomized, no relationship between each key, so is relatively hard. As Elliptic Curve Cryptography system, we want attackers to encounter Elliptic Curve Discrete Logarithm Problem. Once the prime number is big enough, attackers will have trouble deciphering the key. Access control is so comprehensive, such as electronic documents, online television system sand wireless networks and so on, from previous literature; mobile agent technology applied in access control and key management would waste space and do exist some flaws in security, also we still have a lot of works to do on medical application. Hence, we propose these schemes in mobile agent in order to reach improvement, and then analyze of security and try to simulate what attackers will do. We conclude four common attacks: External Collective Attack, Internal Attack, Collusion Attacks and Equation Breaking Attack. As results, attackers are hard to decipher the key because of no relationship between each key and will face Elliptic Curve Discrete Logarithm Problem. We confirm that the proposed schemes can be more efficiently and safety to protect mobile agent.","PeriodicalId":425023,"journal":{"name":"2013 IEEE International Conference of IEEE Region 10 (TENCON 2013)","volume":"917 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126982021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Muniraj","doi":"10.1109/TENCON.2013.6719002","DOIUrl":"https://doi.org/10.1109/TENCON.2013.6719002","url":null,"abstract":"Independent component analysis (ICA) is a technique that separates the independent source signals from their mixtures by minimizing the statistical dependence between components. This paper presents a low-power FPGA implementation of a novel 2-channel fast confluence adaptive independent component analysis (FCAICA) technique for mixture of sub-gaussian and super-gaussian signals. The proposed FCAICA consumes less power and provides the high convergence speed. The reduction in power is achieved by hardware optimization and high convergence (confluence) speed is achieved by a novel optimization scheme that adaptively changes the weight vector based on the kurtosis value. To increase the number precision and dynamic range of the signal, the floating-point (FP) arithmetic units are used. To validate the performance of the proposed ICA, simulation and synthesis are performed with sub and super-gaussian mixtures and experimental results are compared with Fast ICA and SFLO ICA (Shuffled frog Leap Optimization ICA). The proposed low power ICA processor separates the mixture of super and sub-Gaussian signals with maximum operating frequency of 2.91MHz.The FCA ICA, Fast ICA and SFLO ICA algorithms converge to optimal solution at 300ps, 200ps and 500ps, with power consumption of 246.94 mW, 270.76mW and 307.27 mW respectively.","PeriodicalId":425023,"journal":{"name":"2013 IEEE International Conference of IEEE Region 10 (TENCON 2013)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132637740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
