This study investigates the relationship of SEPs with HFOs before and after applying cathodal tDCS (0, 15, 30, 45, 60 min) to human left somatosensory cortex for 15 min at 2 mA. The amplitudes of N20 and P30 evoked by right median nerve stimulation were slightly decreased after cathodal tDCS. Likewise, HFOs were affected by cathodal tDCS but there weren't steadily decrement during the entire HFO, the effects were oscillating depending on the peak of HFOs or the elapse time after tDCS. tDCS may leave the different influences between time- and location-dependent somatosensory processing.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116928673","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}

This paper relates to a diagnosis bearing in low speed rotating equipment of 100 rpm or less, and proposes a method using AE envelope waveform of a 100 k to 1 MHz frequency region. Abnormality diagnosis was enabled even from rotation of 1 rpm by improving the S/N ratio by the method of further amplifying after envelope processing in addition to amplification of AE waveform. Furthermore, a method to remove electric noises in an event counting method and an abnormality judgment method by an event counting method in low speed rotation are proposed. The proposed methods are applied to implement a diagnostic instrument and are actually utilized for the abnormality diagnosis and condition monitoring on sites, which shows the validity of the proposal.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117319094","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}

Both microstrip dipoles and printed dipoles are resonant antennas but printed dipoles are often used to replace microstrip dipoles since they offer somewhat better band width. However, the maximum band width reported to be obtained is not sufficient for many present day high-speed data applications like streaming video, real time navigation and control links, as also applications like medical imaging, broad band EMI measurements etc. A novel yet simple design of printed dipole antenna without flared arms and with shaped ground plane is presented here using which −10 dB return loss band width as high as 41% in L band and below is achieved, a feat hitherto unachieved. By flaring its arms, the same antenna provides −10dB band width as high as 51% in the same band of frequency. Antennas are designed to operate in L band and below so that these can be used in GSM and CDMA wireless applications. Measured results of both antennas show good agreement with the simulated results.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129417630","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}

A story director whilst preserves the authorial intent in the virtual world at the same time delivers good user experience. It is capable of adapting the virtual environment to coerce a participant's experience to conform to a set of provided properties. The framework will be used to develop 3D real time virtual learning environment to prevent aggressive behaviour of school children by inducing affective responses against bullying situations, and thus changing children's behaviour and cognition. As such, issues of narrative management are discussed and a generic narrative module is outlined.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127491019","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}

GNP uses the directed graph structure to represent its solutions, which can express the dynamic environment efficiently. The reusable nodes of GNP can construct compact structures, leading to a good performance in complex problems. In addition, a probabilistic model building GNP named GNP with Estimation of Distribution Algorithm (GNP-EDA) has been proposed to improve the evolution efficiency. GNP-EDA outperforms the conventional GNP by constructing a probabilistic model by estimating the probability distribution from the selected elite individuals of the previous generation. In this paper, a probabilistic model building GNP with multiple probability vectors (PMBGNPM) is proposed. In the proposed algorithm, multiple probability vectors are used in order to escape from premature convergence, and genetic operations like crossover and mutation are carried out to the probability vectors to maintain the diversities of the populations. The proposed algorithm is applied to the controller of autonomous robots and its performance is evaluated.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129992377","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}

Although the previous zero-block decision algorithm in [1] achieves significant computation improvement, computation performance is still limited for high bit-rate coding. To obtain better computation efficiency at high bit-rate, another work in [2] suggests another zero-block decision algorithm, using zero-blocks of both 8×8 and 4×4 DCT coefficients to describe video sequences in detail, including global and local stationary characteristics. The experimental results reveal significant computation improvement for high bit-rate coding, but computation performance at low-bit rate is slightly worse than the previous algorithm [1]. This study proposes an advanced decision algorithm which accounts for advantages of both algorithms to greatly improve computation. Improved computation reduction is very momentous for all bit-rates while still preserving high coding efficiency.","PeriodicalId":101683,"journal":{"name":"TENCON 2010 - 2010 IEEE Region 10 Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131082129","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}
