On this situation, it is probably that the faults that occurred will involve the two different voltage levels at the same time in a same tower. This paper presents the study of the effect of cross-country fault on distance protection. This study has been performed on a simple model circuit in transmission line. The cross-country fault analysis is more complicated than basic fault because it has to be considered fault locations simultaneously in the analysis. PSCAD/EMTDC software is used to perform the modeling and analysis of the effect of cross-country fault on distance protection. From simulation result, it can be identified the effect of cross-country fault on distance protection and the result can be compared with the basic fault analysis.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124664933","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 presents one more step towards safety of driving through an application called Crash Prediction System (CPS). That analyzes driver's behaviour in real time and predicts that whether driver is suitable or not for driving. This system requires various profile of driver's detail for accurate prediction and gives result like Fit, Unfit and Partially Fit. For this application a concept of Data Stream minning is used with Principle Component Analysis (PCA) and Hidden Markov Model (HMM) techniques. Other interactive feature for this application is that, it used for mobile device. A large range of application is running on mobile device which are facing problem like a memory, computational capability, battery and many more. For eliminating all these issues there is a platform known as Android which we used for this application. Experiment result of CPS on Google Android platform is presented, proving the effectiveness of the proposed system.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123848722","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 main problem of visual object categorization is the semantic gap (categorization problem). Currently, several researches show that using a texture feature could improve the categorization problem especially when using orientation descriptors. Mainly, in this research the edge histogram descriptor has been selected to extract the texture feature. Obviously, the main demerit of using this kind of texture descriptor is it uses single orientation to extract the texture feature. Therefore, the Gabor filter has been proposed to improve the performance of this descriptor by constructing different feature maps based on different scale and orientation. To demonstrate the performance of the proposed method, the first 20 classes of the Caltech 101 dataset have been used. Moreover, we compared the performance recognition of the proposed method in two different domains, namely spatial and frequency domains. Finally, the result shows that the proposed method in the spatial domain outperforms the proposed method in the frequency domain. This is because of losing some of the basic raw data though using Fast Fourier Transform algorithm in converting the system to the frequency domain.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132914767","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 presents the comparison of Zernike Moment (ZM) and Discrete Cosine Transform (DCT) for image reconstruction in noise environment. Two types of images used are gray scale and binary. The original images are corrupted with three different noises that are Salt and Pepper, Gaussian and Random. Both original and corrupted images are reconstructed using Inverse Zernike Moment and Inverse Discrete Cosine Transform. The performance of each algorithm is measured by evaluating Peak Signal to Noise Ratio (PSNR) for the reconstructed gray scale of pixel size 64×64 and binary of pixel size 30×30 images. The comparison of PSNR values between the two techniques proves that Zernike Moment is less sensitive to noisy images compared to Discrete Cosine Transform.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125104026","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 range of studies to describe and analyse the situation qualitatively and quantitatively have been performed, however we have not been able to find any study containing a decision support tool focusing on this issue. This paper presents a simulation model, built using the System Dynamics methodology. The model focuses on enabling disabled people to move from welfare to work, incorporating attitudes of disabled people and employers. The model is designed to cover selected factors that are believed to enable and encourage disabled people to take up jobs. It is intended to be used by policy makers, disability organisations, and individual citizens, and support more targeted discussions among them. To build the underlying model we have conducted an extensive literature review, and two surveys on attitudes of disabled people and employers.

Along with the influence of APs to the performance of the model built, we analyze the set of acoustic features extracted for each phoneme to see how robust they are in the noise. All the experiments were conducted on TIMIT database. The results of the experiments show that there are APs, which have nice separating property and, therefore, improve the performance of a system if used with MFCCs, however, they are not robust to noise. On the other hand, there are APs, which do not have this property, but possess the intrinsic stability in noisy conditions and, as a result, add some robustness to a system.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114717682","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, it is not an easy task, because 1) packet flows generated by cache coherence events do not conform to the Poisson process, traditional queue theorem can't be applied to the performance analyzing for the NoCs that support cache coherence, 2) broadcast or multicast operations, which will duplicate the cache coherence packets, makes the analysis much more complicated. To address these challenges, in this paper, we use the stochastic network calculus to analyze the end-to-end delay bounds of different cache coherence policies. Specifically, we utilize Markov-modulated On-Off (MMOO) flow to model the arrival process of cache coherence events, and then deduce the general end-to-end delay bounds for different cache coherence policies. Furthermore, to deal with packet duplication issues in broadcast or multicast operations, we develop an analytical model based on scaling functions to study their impacts on end-to-end delay bounds.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116020460","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 difference among these three techniques are, CHT employs a segmentation technique to highlight the edges of interest and the circular shape of the iris is detected using the equation of circle, DIDO makes use of integro differential operator for locating the iris and pupil regions while CBD is developed based on the equation of circle by first selecting two points at the iris region: one at the center and the other one at the circumference of the iris. Once this selection has been made, the computation of the outer iris boundary takes place. The same procedure is repeated for the construction of inner iris boundary. The circular iris region can be un-wrapped into rectangular form for the purpose of pattern recognition analysis. The iris localization was conducted on iris images taken from healthy women free from Human Papilloma Virus (HPV). The results show that CBD is able to localize the iris region for all tested iris images while using DIDO and CHT, not all iris images can be localized precisely.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116448544","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}
