We use this sort of system for processing of data streams that can come from different sources such as web sites, sensors, mobile phones or any set of devices that provide real-time high-speed data. Typically, these systems are concerned more with the throughput in data processing than on fault tolerance. However, depending on the type of application, we should consider fault tolerance as an important a feature. The work describes some of the main strategies for fault tolerance - replication components, upstream backup, checkpoint and recovery - and shows how each of the four systems uses these strategies. In the end, the paper discusses the advantages and disadvantages of the combination of the strategies for fault tolerance in these systems.","PeriodicalId":311436,"journal":{"name":"Journal of Emerging Technologies in Web Intelligence","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127125084","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}

WiMAX forum defines specification for QoS provisioning for manufacturing of WiMAX equipment by different vendors but the amount of bandwidth allocated to specific service in WIMAX is still an open issue. A number of algorithms have been presented to satisfy the diverse QoS requirements for traffic in WiMAX networks. The focus of all these algorithms is towards real time traffic. Non real time traffic like nrtPS and BE is quite often neglected. This paper is an attempt towards fair allocation of resources to non real time traffic simultaneously taking care of real time traffic also. The approach uses uncertainty principles of fuzzy logic to calculate new weights for different flows and makes allocation based on these new weights. Simulation results show that the proposed scheme was able to meet required performance levels for both kinds of traffic.","PeriodicalId":311436,"journal":{"name":"Journal of Emerging Technologies in Web Intelligence","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128186356","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 wireless sensor nodes are typically powered by non-rechargeable batteries which makes them constrained in terms of energy. As communication energy represents the largest part of the energy consumed in sensor nodes [1], so energy efficient routing is one of the main issues to prolong lifetime of wireless sensors networks. This paper proposes a hierarchical routing protocol called MGI-LEACH for homogeneous wireless sensor networks  based upon the framework of  LEACH such as the network is divided into multi groups to prevent the concentration of cluster head in a particular area of ​​the network, and the cluster head selection is based on high residual energy and a short distance from the base station (BS) in each communication round, which minimizes the communication energy of wireless sensor nodes, and hence, increases lifetime of the whole network. Simulations using MATLAB software show improved lifetime in different levels of Grouping compared to the classical algorithm LEACH.","PeriodicalId":311436,"journal":{"name":"Journal of Emerging Technologies in Web Intelligence","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121650461","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 method aims to track these people in complex situations such as players on a soccer field. Each person in the image is represented by several control points which are obtained using a color version of the Harris algorithm detector. Each control point is characterized by the local appearance which is a vector of local characteristics. Then we determine the rules that define the skin regions in three different color spaces such as RGB, HSV and YCbCr, and we apply these rules to our images to segment skin regions. Using a set of control points and skin regions allows us to track a person by matching control points based on the measure of ZNCC correlation «Zero mean Normalized Cross Correlation». The simulations and experimental results show the robustness of our algorithms in terms of stability and convergence. Performance is illustrated by some examples. Thus, our method fits well with the noise conditions.","PeriodicalId":311436,"journal":{"name":"Journal of Emerging Technologies in Web Intelligence","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114252127","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 key problems within medical image analysis techniques are segmentation and shape feature extraction that will be referred to in this paper. Segmentation of grayscale medical images can be difficult since the intensity values between healthy tissue and tumor may be very close. PET/CT provides more accurate measurements of tumor size than is possible with visual assessment alone. In this paper, segmentation method for the detection of liver tumor in PET/CT scans is proposed. The images are denoised using median filter and binary tree quantization clustering algorithm is used for segmentation. Finally ROI selection and shape feature extraction is performed on the selected cluster to quantify the size of the tumor and to check the accuracy of our method with original image and K-means Clustering method.","PeriodicalId":311436,"journal":{"name":"Journal of Emerging Technologies in Web Intelligence","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127368763","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}
