The open-loop is composed of two half-wave stepped-impedance resonators (SIR) with high-impedance short-circuited ends, which is equivalent to an inductor for providing coupling between the resonating modes and hence bandwidth control. Moreover, with the aid of source-load coupling which is employed in the second circuit, extra transmission zeros can be created to close the passband edges, greatly improving the performance in transition bands. The measured results show good agreement with the simulation.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121209149","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}

However conventional RSS fingerprinting approach becomes inefficient when used for localization of heterogeneous mobile devices, where each mobile device may need an individual fingerprint database for localization purpose. In order to overcome this limitation, this paper presents a novel RSS correction approach for localization of heterogeneous devices. In this approach, during the calibration phase, the full fingerprint database is constructed only for one baseline device and the RSS difference between the new device and the baseline device is obtained based on a limited number of common reference points. During the online localization phase, such RSS difference will be used for RSS correction to localize the new device using the fingerprint database of the baseline device. Significant calibration effort is saved for the new device by avoiding setting up its full fingerprint database. Real testing results show that the proposed RSS correction strategy can improve the localization accuracy significantly from that without RSS correction.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126181097","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}

In this paper a clothing animation system is presented which incorporates a novel adaptive update method for over-stretching treatment. This method differs from the traditional treatment by adaptively updating those cloth vertices most likely caused by overstretching first. The key observation that makes this possible is that the vertices most likely to undergo over-stretching are usually those experiencing the greatest forces, and updating those vertices first can effectively solve the over-stretching issue. Simulation results show that the proposed method can cut the processing time by about a half and produce results that are visually appealing.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130533183","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}

As the Internet becomes more open to public, most people and organizations prefer to use online services. At the same time, the Internet security problem is becoming more severe. An effective and feasible protection measure for network security is necessary. Intrusion detection system (IDS) is a typical measure used to provide protection for information systems. In order to detect unknown attacks, anomaly detection technique is a commonly used method. Meanwhile, many scholars are studying more effective and easy-to-use anomaly detection methods. In this paper, a new intrusion detection approach inspired by the function of biological memory cell is proposed. The detectors in this approach (which called memory detector) are more effective than common detectors. The generation method of memory detector is detailed. In order to analyze and evaluate the performance of this approach, comparative experiments are implemented with training and testing data from “Knowledge Discovery and Data mining cup 1999” (KDD99) dataset. The results show that our approach provides better performance than ordinary anomaly detection approaches with higher true positive rate and lower false positive rate.","PeriodicalId":321908,"journal":{"name":"2012 International Conference on Computational Problem-Solving (ICCP)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129135360","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}

In this work, a simulation platform based on Rigorous Coupled Wave Analysis (RCWA) method is developed to simulate diffraction problems of various grating structures.

This enhanced implementation of rigorous coupled-wave analysis can be successfully applied to transmission and reflection planar dielectric and absorption holographic gratings, or some more complex grating structures. As a professional simulation platform specially designed for grating structures, it's capable to calculate the diffraction orders of arbitrarily shaped grating structures illuminated by different polarized wave.
