Although GPS can give approximate position of the mobile users, it is usually limited indoor due to the degradation of signals by the building structures. While various alternative WIFI localization techniques have been proposed for indoor uses, accurate results are hard to achieve due to the instability nature of wireless signal. In this paper, we discuss the performance of multi-trilateration and fingerprinting localization techniques in the context of mobile applications. The implementation of WIFI localization on mobile allows the users with WIFI-enable devices such as smartphone to locate their position and/or navigate themselves within the building. During our experiments, we noted that the selection criteria that involves selecting available access points to be used as a reference position considerably affect the accuracy of the positioning calculation. The tradeoff between multi-trilateration and fingerprinting in terms of correctness, computational complexity and system resource consumption have been discussed. Additionally, we proposed the suitable configuration for these localization algorithms as a means to achieve more accurate positioning results.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131636433","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 maintenance data from 237 power transformers in central region are used to analyze the risk factors' ranking and scores. The weights of the risk factors are assigned by experienced maintenance crews. The risk assessment factors and scores are categorized with equal weight into two parts: the history of the transformer; and the current condition of the transformer. The weighted scores from both parts are calculated to obtain the health index (HI) for the power transformer. The HI is then plotted on a square matrix called the “health-index matrix”, which interprets the risk condition for that transformer. The risk assessment method proposed in this paper is applied to three power transformers in different load areas in central region of PEA. The results show that the method successfully detects the risk condition of those transformers. Therefore the proposed method can create an efficient preventive maintenance plans for power transformers in central region of Provincial Electricity Authority.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134378007","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}

It can provide a reliable, scalable, energy efficient multipath routing mechanism for data transmission to Base Station (BS). This scheme is also classified as a routing technique supporting virtualization WSN (VSN) as it can share network resources between different VSNs for achieving resource efficiency. In this paper, we propose a new dynamic switch process for EMRP that use the current energy value of relay and backup node and evaluate the performance of new switch strategy in terms of total residual energy, load balance, network lifetime and rate delivery compared with the old scheme. Via simulation, we realize that the newEMRP protocol can achieve better rate delivery and load balance than EMRP. Furthermore, we analyze and evaluate an application case of virtualization in OMNET++ that utilizes our two routing algorithms in order to investigate the capability of collaboration and network resource sharing between different VSNs. Our simulation result shows that both schemes can achieve collaboration and efficient network resource sharing for the purpose of virtualization. More concretely, the newEMRP protocol can achieve better capability of network resource sharing than the old protocol.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124451224","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}

Fail to detect this defect might lead to fatal hard disk drive failure. In general, corrosion defect was found after the end of process. The fundamental methodology used to measure corrosion defect in head magnetic process of hard disk drive manufacturing is Electrochemical impedance spectroscopy (EIS). This method applies a low frequency voltage to a chemical cell in order to measure corrosion rate which is defined as a reaction of material in aqueous solution. The data obtained from EIS measurement method are complex and thus hard to analyze. Furthermore, EIS method is destructive materials measurement and the obtained results cannot well predict corrosion behavior of the system. However, head magnetic materials/slider is a stack of three materials in layers i.e. soft magnetic layer, diamond like carbon (DLC) layer, and photoresist layer respectively. These three stack layer of slider can be replaced by R-C equivalent circuit. Nyquist plot and Bode plot are used to observe the frequency response of the equivalent circuit. This observation can help in prediction of corrosion behavior before starting of mass fabrication or transferring to new materials. This work shows that the results obtained from an equivalent R-C circuit model of copper substrate coated with photoresist and the one obtained from EIS method are comparable. It should be noted that the parameters of R-C equivalent circuits are modified for corrosion behavior studying according to two different types of photoresists.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125413034","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}
