This can be completed by checking the graphs when the network is fully functioning but subject to failure. There is no known algorithm that can measure the reliability in a polynomial time, and hence measuring the reliability by means of simulation is a preferable choice. The goal of this paper is to check the network reliability, by means of simulation using different methods, first generating a network using the random graphs, and second generating a network using regular graphs. Within this paper, I will focus on the all-terminal problem in which a path between every pair of nodes is checked using the Union and Find method.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133359225","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 input of a video stabilization system is a video sequence of relatively static scene, which is ragged due to a mechanical shaking of the camera. This type shaking is often amplified by a camera zoom. Because of this, the video stabilization algorithms are often useful in combination with the security monitoring systems, which often must deal with the zoomed scenes. The video stabilization means a correction of such video sequences, so the stabilized output appears as steady. Our algorithm is based on the fixed-point arithmetic. For this reason it is suitable for use on devices that are not optimized for fixed-point arithmetic, like the DSP architectures and other embedded systems.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133372967","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}

PCNAD is an improvement to PAYL system which is considered one of the complete systems for payload based anomaly detection. PAYL takes into consideration the entire payload for profile calculation and effectively for anomaly detection. Payload length is very high on port numbers like 21 and 80. Hence it is difficult to apply PAYL on high speed, high bandwidth networks. We use CPP (content based payload partitioning) technique which divides the payload into different partitions depending on content of payload. PCNAD does payload based anomaly detection using a few CPP partitions. We demonstrate usefulness of the PCNAD on the 1999 DARPA IDS data set. We observed 97.06% accuracy on port 80 using only 62.64% packet payload length with small false positive rate. This is a significant improvement over PAYL approach which uses 100% of the packet payload for anomaly detection.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"24 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114034715","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 approach, images of both model objects and partially occluded unknown objects are firstly pre-processed. Then the objects in images are represented by their different order moment invariants based on boundary partitioning of the silhouettes. Afterwards, the match between the model objects and partially occluded unknown objects are implemented. Finally, the unknown objects can be recognized based on the feature calculating and matching. The experiment results show that this algorithm is effective in the recognition of partially occluded objects and robust in invariance to the transformation, scaling and rotation of the objects in images.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122697258","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}

There are several binary PSO methods proposed in the literature. Firstly, binary PSO was presented by the father of the PSO method. Then several other methods have been proposed claiming better results. In this work, we analyzed these BPSO methods on maintenance scheduling problem for condition based maintenance system. Evaluation of these methods revealed that their difference mainly focuses on the calculation of velocity vector. Thus, we focus on/compare different velocity calculation methods in BPSO on maintenance scheduling problem in Condition Based Maintenance, which has been presented with Genetic Algorithm in our early work. The tradeoff between maintenance and failure is quantified in risk as the objective function to be minimized.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116060086","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, by the end of the recording period, such tapes may hold many useless scenes which need to be eliminated. In order to reduce the time in reviewing these worthless scenes while seeking for a specific object, an approximation technique must be considered. In this article, we propose a new technique for finding the minimum bounding rectangle of objects which appear in a specific bitmap image. The minimum bounding rectangle of an image object is the Rectangle containing the object such that the sides of the rectangle touch the object boundaries. The dimensions and locations of the minimum bounding rectangle of an object can be utilized as features to identify the corresponding object.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127516687","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}
