Therefore, the investigation of PD characteristics and particle size and position on the spacer surface are the significant steps toward the reliability improvement of the GIS equipments. This paper presents the use of Back-Propagation Artificial Neural Network (BP-ANN) technique supplemented with Principal Component Analysis (PCA) as the PD pattern recognition tools for the estimation of the particle size (length) and position on the spacer surface in a simulated GIS. PD features acquisition was performed by collecting their fingerprints from the measurements carried out using IEC 60270 method. The role of PCA is to reduce the dimension of the collected PD fingerprint data. The obtained results show that PCA can significantly improve the BP-ANN performance in terms of execution time. Without PCA, 88% and 92% accuracies can be achieved when BP-ANN was implemented with 1 and 2 hidden layers, respectively. With the integration of PCA, execution times were greatly reduced while retaining fairly high accuracy, i.e. 88% and 88%. Thus the proposed method is a contribution in development of the tool for improving the reliability of GIS.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116897240","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}

Here, the scattering parameters, i.e. reflection coefficient (S11) and transmission coefficient (S21), are extracted from the electric fields obtained on different observation planes closed to the material. The principal used to analyze electromagnetics (EM) wave scattering based on FDTD method is a wave orthogonality and discontinuity which occurs inside the rectangular waveguide. To validate the result of FDTD method, another analysis is carried out by using a commercial software, namely HFSS®. From the result, it shows that the FDTD method has a good agreement qualitatively compared to the commercial software with some discrepancy on the S-parameter curve. The disparity of results occurs as the numerator of equation to calculate incident and reflection waves tends to be very small with the increase of frequencies which are being calculated. Moreover, the discrepancy is also evoked by the appearance of higher order modes and the irregularity of EM field inside the rectangular waveguide particularly when it is loaded with anisotropic dielectric material.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115819049","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}

One of the important requirement is its security. This communication has a high risk to be attacked by jamming which generated by the adversary. The other important requirement is network flexibility to handle its high mobility and information exchange in a big order. To fulfil those special requirement of tactical communication, OFDM system is equipped with channel coding and interleaving to handle information damage caused by jamming. The jamming strategy used in this research is single-tone and multitone jamming which strike while information signal pass the AWGN channel. In this research. evaluate the performance of OFDM system which is equipped with Convolutional Encoder and Interleaver with various schemes. By using a half-rate convolutional encoder, for both parameters BER and interleaving gain, helical-scan interleaver scheme shows the best performance among block and random interleaver. However due to its complexity in applying this scheme, block interleaver which is the second best is preferred.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"689 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133970537","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}
